The content is provided for information purposes only. The problem lies in the way findings are presented. If a group of researchers, for example, applies something (chemical, food, energy, etc.) that is to cause an effect on something else (nerve cells, populations, inanimate objects, etc.) and finds the amount of change caused by the main thing that is being studied is “significant” but the change in the control group is not, they cannot then, reasonably compare the two results and come up with something that they consider significant unless the differences between the two are actually statistically significant (based on additional research).Why such errors appear in so many research papers is open to debate. Whether it’s due to researchers wishing to overstate their findings, ignorance, or simple sloppiness, it’s clear that more scrutiny and peer review must be done by researchers before submitting their work. Of course, that’s only half the equation, why are journals who obviously take their reputations very seriously not properly vetting such papers before publishing them?In their study, the group reviewed 513 papers published in five different highly regarded journals over a two year period. They found half of the papers (where such an error was possible) had the error in them. In addition they also found that when looking at 120 articles published on Nature Neuroscience (with cell and molecular themes) that 25 had the error in them.Clearly there is a serious problem here; this research project highlights a problem that is likely present in other areas of science as well; namely the inaccuracies present in science journals, mainstream science magazines, the media and perhaps even in classroom lectures. Failing to check for and fix simple statistical inaccuracies in papers presenting results obtained in research, calls into question their very integrity.Hopefully research studies such as this one will cause alarm both in the research and publishing communities and bring about better controls on both.

In practice, this comparison is often based on an incorrect procedure involving two separate tests in which researchers conclude that effects differ when one effect is significant (P < 0.05) but the other is not (P > 0.05). We reviewed 513 behavioral, systems and cognitive neuroscience articles in five top-ranking journals (Science, Nature, Nature Neuroscience, Neuron and The Journal of Neuroscience) and found that 78 used the correct procedure and 79 used the incorrect procedure. An additional analysis suggests that incorrect analyses of interactions are even more common in cellular and molecular neuroscience. We discuss scenarios in which the erroneous procedure is particularly beguiling.via Guardiancenter_img Explore further US scientists significantly more likely to publish fake research ( — Sander Nieuwenhuis and his associates from the Netherlands have done a study on one particular type of statistical error that apparently crops up in an inordinately large number of papers published in neuroscience journals.

For faster battery charging try a quantum battery

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The physicists, Felix C. Binder, et al., have published a paper on the quantum battery, which they call “quantacell,” in a recent issue of the New Journal of Physics.”There has been much interest in the question if quantum physics can provide any advantage in thermodynamic processes (thermodynamics being the study of work and heat and their interconversion),” Binder, a physicist at the University of Oxford, told “Our paper demonstrates with an example that a significant advantage can indeed be achieved when a short process duration is desired—quantum correlations (‘quantum entanglement’) can lead to a significant speedup.”The scientists investigated a quantum battery made of qubits, which can take a variety of physical forms, such as ions, neutral atoms, photons, etc. Qubits can exist in either one of two states or a superposition of both states at once. In a quantum battery, the two states represent different energy levels. Charging a quantum battery means changing a qubit’s state from a lower energy level to a higher energy level, while using (discharging) the battery does the reverse. The scientists call these particular qubits “work qubits” (or simply “wits”) because they can store energy that can later be used to do work. Citation: For faster battery charging, try a quantum battery? (2015, August 3) retrieved 18 August 2019 from Besides decoherence, another roadblock to using quantum batteries for real-life applications is that the amount of energy that they can store is tiny compared to the energy needs of, for example, mobile phones or electric vehicles.”The energies of quantum systems tend to be many orders of magnitude smaller than even the smallest energies used by day-to-day appliances,” explained coauthor John Goold, a physicist at The Abdus Salam International Centre for Theoretical Physics in Trieste, Italy. “‘Size’ is here a question of energy scales. Our study is a theoretical proof-of-principle that quantum physics can provide a speedup in depositing energy into a system. These speedup effects would be relevant in two cases: 1) Mechanical devices become small enough that energy scales are comparable to current implementations of quantum systems. 2) Quantum systems are scaled up and robustly controllable at energy scales that are of practical importance.”To better understand the potential applications of quantum batteries, the researchers plan to further investigate the quantum effects of thermodynamic processes. The big question is, can a quantum battery produce work (directed energy) rather than simply heat (disordered energy)?”What we call ‘quantum batteries’ in the paper exists in labs: Any controllable quantum system with stable energy eigenstates can be understood as a battery,” Binder said. “The question is rather if the thermodynamic viewpoint will be helpful for quantum experiments with systems like ions, cold neutral atoms (for instance, on an optical lattice), condensed matter systems (for example, superconducting qubits and circuit quantum electrodynamics), or light.” © 2015 (—Physicists have shown that a quantum battery—basically, a quantum system such as a qubit that stores energy in its quantum states—can theoretically be charged at a faster rate than conventional batteries. This “quantum speedup” arises from quantum entanglement among multiple qubits, which essentially provides a shortcut between the qubits’ uncharged and charged states, allowing for faster charging. A Bloch Sphere showing the “cone of states” that achieve maximum average power, i.e., the fastest charging time. The quantum speedup is due to the shorter distance that has to be traveled between states when entangling is permitted. Credit: Binder, et al. CC-BY-4.0 (A) An array of qubits can be charged either (B) in parallel or (C) globally. The results show that, when global entangling operations are allowed on the array during charging, the charging rate increases as the number of qubits increases. Credit: Binder, et al. CC-BY-4.0 Flying qubits make for a highly resilient quantum memory So far, this description is similar to how a conventional battery works. However, the important difference is that, as quantum systems, qubits may be entangled, meaning the qubits are so strongly correlated that an entire qubit array can be described by the same quantum state. Here, the researchers have shown that one consequence of entangling the qubits during the charging process is that it means a shorter distance has to be traveled through state space—that is, between the low and high energy states—than would be required without entanglement. The scientists showed that, the more qubits, and hence the more entanglement, the faster the charging process. In the example protocol, the charging time is inversely proportional to the number of qubits. So hypothetically, if one work qubit took an hour to charge, six work qubits could be charged in 10 minutes. In reality, however, typical quantum systems cannot remain quantum for anywhere near this length of time due to decoherence—interactions with the surrounding environment that destroy the quantum effects.

Optical rogue waves reveal insight into real ones

first_img Explore further (—Rogue waves in the middle of the ocean often appear out of nowhere and vanish just as quickly. But in their short lifetimes, they can generate walls of water 15 to 30 meters (50 to 100 feet) high, crashing down with enough force to sink even the largest ships. Although rare, when rogue waves do occur they often take ships by surprise because their formation is not well-understood, and so they are difficult to detect in advance. Since tracking down a rogue wave in order to study it would be difficult and dangerous, researchers have come up with another way to study these waves: creating a small-scale optical version in the lab that forms by similar underlying mechanisms, except in light instead of water. In the past few years, scientists have realized optical rogue waves in optical fibers, photonic crystals, and other optical systems.Now a team of researchers, Christopher J. Gibson, Alison M. Yao, and Gian-Luca Oppo at the University of Strathclyde in Glasgow, Scotland, has proposed a new way to produce optical rogue waves in a two-dimensional space. Their work is published in a recent issue of Physical Review Letters.”By understanding the mechanism for generating rogue waves, we can devise methods to detect their precursors—in our case, multi-vortex collisions,” Oppo told “By knowing where there is a high probability of rogue waves occurring, ships can change course to avoid catastrophic events.”In the new proposed mechanism, optical rogue waves could form by a sequence of events that starts with a small instability in the regular wave pattern. This pattern instability first leads to a phase instability (the waves’ shapes begin to change), which then leads to an amplitude instability (the waves’ heights begin to change), which eventually creates swirling vortices. If there are enough vortices, then multi-vortex collisions can occur and produce a large, short-lived spike—the optical equivalent of a rogue wave.”We can realize vortex-mediated turbulence to channel large powers into a single, huge, narrow peak of light,” Gibson said.As the researchers demonstrated, these peaks of light can be up to 27 times higher than the average fluctuation. In oceanography, waves with peaks 8 times larger than the average wave are already considered very dangerous.The researchers also showed that the new formation mechanism should be observable in a wide variety of systems, including different types of lasers, semiconductors, liquid crystals, chemical reactions, and fluid dynamics.In the future, studying this formation mechanism in the lab could lead to a better understanding of oceanic rogue waves, and eventually help warn ships to stay away from these rare but deadly encounters. “We plan to extend the research and control of extraordinarily large fluctuations to several quantum optical systems and to better quantify precursors of these rare events in the presence of vortices,” Yao said.

Deuterated formaldehyde detected in protostar HH 212

first_img © 2018 HH 212 is a low-mass protostellar system located some 1,300 light years away in the Orion constellation. Previous studies of this protostar, conducted in 2016 and 2017, found that its “hot corino” (the warm inner region of the envelope surrounding the low-mass protostars) contains deuterated water (D2O) and singly deuterated methanol (CH2DOH).Recently, a team of scientists led by Dipen Sahu of the Physical Research Laboratory (PRL) in Ahmedabad, India, has analyzed archival data obtained by ALMA, which observed HH 212 in December 2012. The analysis allowed the researchers to identify an emission of another molecule from the protostar’s hot corino – deuterated formaldehyde.”In this paper, we use ALMA archival dataset 2011.0.00647.S and report emission of deuterated formaldehyde line from central hot-corino region,” the authors wrote in the paper. The study reveals that the emission of HDCO is assumed to be optically thin and is limited mainly to the inner 200 AU from the center of HH 212. The emission is concentrated in a circular region around the central protostar position and is elongated along the jet direction. However, Sahu’s team was not able to infer conclusively whether the elongation is real or due to the effect of the synthesized beam size.The researchers assume that the HDCO emission originates near the central hot region, given that the emission is almost symmetric around the systematic velocity between 1.6 and 2.0 km/s. The column density of HDCO was calculated to be 100 trillion cm−2. Furthermore, the scientists revealed that HDCO emission experiences a rotation, most likely associated with the disk wind or rotating environment. However, due to limited resolution of the observational data provided by ALMA, the authors of the paper cannot select the most plausible scenario at the moment.In order to determine the origin of HDCO emission, the researchers compared it with methanol (CH3OH) and C17O emission. For instance, they found that HDCO emission is more extended than methanol, and HDCO has a red-shifted peak which is absent in methanol emission.”We compare HDCO line with other molecular lines to understand the possible chemistry and physics of the source,” the paper reads.The authors concluded that the deuterium fractionation of formaldehyde is relatively higher than methanol in the central region of HH 212. They assume that the gas phase formation of deuterated formaldehyde is active in the central hot region of the protostar.”From the possible deuterium fractionation, we speculate that the gas phase formation of deuterated formaldehyde is active in the central hot region of the low-mass protostar system, HH 212,” the researchers wrote in concluding remarks. Using the Atacama Large Millimeter Array (ALMA) in Chile, a team of researchers has detected the emission of deuterated formaldehyde (HDCO) from the hot inner region of the protostar HH 212. The finding, reported January 20 in a paper published on the pre-print repository, could be helpful in our understanding of chemical processes in this protostar and in similar objects.

Credit: Codella et al. 2014. More information: Deuterated Formaldehyde in the low mass protostar HH212, arXiv:1801.06699 [astro-ph.GA], a nearby (400 pc) object in Orion, is a Class 0 protostellar system with a Keplerian disk and collimated bipolar SiO jets. Deuterated water, HDO and a deuterated complex molecule, methanol (CH2DOH) have been reported in the source. Here, we report the HDCO (deuterated formaldehyde) line observation from ALMA data to probe the inner region of HH212. We compare HDCO line with other molecular lines to understand the possible chemistry and physics of the source. The distribution of HDCO emission suggests it may be associated with the base of the outflow. The emission also shows a rotation but it is not associated with the Keplerian rotation of disk or the rotating infalling envelope, rather it is associated with the outflow as previously seen in C 34 S. From the possible deuterium fractionation, we speculate that the gas phase formation of deuterated formaldehyde is active in the central hot region of the low-mass protostar system, HH212.

Get setNH7

first_imgAccording to you how has music in India changed over the years?There are some truly inspiring artists coming up now. I love hearing the kind of attitude that young artists tend to have. Yet there is sometimes a lack of knowledge as per how the scene got this way in the first place and the people that made it happen. For the most part, I am excited at the state of indie music in India.Could you tell us more about Karsh Kale Collective? Well, the band kind of came together when I came to India to promote my album Cinema.  I had played with some of the musicians before and had to put a band together for a series of shows supporting the album’s release. Things worked out so well that the same band went on to do an episode of Coke Studio and the rest is history. For me, it is the dream band I have always been striving to put together. I get to explore rock, electronica, classical and film music and so much more, all at the same time with this band. I also see myself improving as a musician collaborating with such a great and creative group of artists.  The band consists of Warren Mendonsa, Ajay Prasanna, Jai Row Kavi, Jayant Luthra, Benny Dayal, Shilpa Rao and Karsh Kale. Also Read – ‘Playing Jojo was emotionally exhausting’At NH7 Weekender in Delhi, who all will you be performing with from NH7 All Stars? What are your expectations from the Delhi leg?Bacardi NH7 Weekender is an amazing festival, and a place where indie music comes together, and I love playing at the festival each year. The Karsh Kale Collective + NH7 All Stars, which is the finale set for the festival, is a celebration of all the music that’s played at the festival, and the music that we’ve grown up on.  Also Read – Leslie doing new comedy special with NetflixHas your sense of music changed with time? Any new favourites or preferences recently?I like different aspects of different artists and take inspiration from all angles. Today in India there is a wellspring of new and fresh takes on music, like Shaa’ir + Func, Dualist Inquiry, Nucleya, Advaita, and of course, the veteran rockers that have been keeping it alive for years, like Pentagram, Ankur Tewari, Midival Punditz, Blackstratblues, etc. Tell us about your most memorable performance or gig. So many to name. I’d have to say generally the Bacardi NH7 Weekender experience tends to take the cake as it seems to be a culmination of a lot of energy, and we are all surrounded by friends and fellow artists, so there is always an added excitement. We’re performing the finale concert along with some special guests for all four festivals this year, across Pune, Bangalore, Delhi and Kolkata.What next for Karsh Kale?I plan to do more in terms of writing and recording with the Collective, not to mention more concerts. I am also working on an album of my own vocal songs, which is a first for me. I’ll be collaborating with Salim Merchant, Gaurav Raina from the Midival Punditz, Nitin Sawhney and Warren Mendonsa on songs for this project.  I have wanted to do a vocal record for a long time, but now I feel my voice is ready. There are a few film projects on the cards as well, that are more interesting and left field.  NUCLEYAWhy the name Nucleya? How does it describe you?Nucleya was my e-mail password when I was in school. I was looking for a name, and this was what occurred to me.Tell us a little bit about your own musical journey.My parents are avid music listeners. We had music in the house all the time. My father likes Indian film music from the 50s and 60s, my mum is very fond of Ghazals, and brother prefers electronic music, so I was exposed to many different genres at once. When I was in school, my father bought me my first ever computer, and on that I started making electronic music. With a few like-minded friends, I formed my first band Bandish Projekt. Being part of a band, I was making one particular style of music for about 10 years. I wanted to explore and experiment. About five years ago, I started Nucleya, and with this moniker I started exploring and came across dubstep and instantly fell in love with it. I have major dubstep influences in my music and I chose this genre because it has strong bass throughout, and simple half time drums. What is your opinion about the future of EDM in India? When you started it was at a nascent stage, how has it changed according to you?The electronic music scene has changed drastically. Back in the day, there were no venues for electronic music and now we have festivals. But it’s not just that – all the best electronic musicians from around the world headline our festivals, play at clubs in India and support our artists too, so that’s awesome!What were your thoughts behind developing your new album Koocha Monster?My new EP, Koocha Monster, celebrates Indian street music in a slightly more bass heavy format. In Hindi, streets are called gali koocha, so the word koocha comes from there, and the word ‘monster’ comes from the sound of the bass. As far as the sound of the EP is concerned, the EP is a hybrid of many genres. I wanted to explore Indian street music and various sub genres of bass heavy music like Moombahton, trap, dubstep and reggae. I love sampling dialogues, news, so that’s there as well.What can we expect from your set at NH7 Weekender in Delhi?I plan to play a very special visual set this time, where the visuals are all mashed up and resynced to the beat live, which will be very interesting. I also plan to play some unreleased music.You have performed at several international and national festivals. What are the main differences you see amongst the audiences there and back home?Each venue is a different experience regardless of whether it’s in India or international. The response I get in Pune is so different as compared to the response I get in, say, Delhi. The same thing is applicable to all international gigs I have played so far. In some places the energy is very high, and in some places not so much. I have played some gigs where people preferred to just stand and listen to what I’m playing rather than dancing, which is amazing too.last_img read more

Guardians of fasting students threaten to join 7dayold stir

Govt ushers in sea change in agri aqua culture in state

first_imgKolkata: Bengal government has brought about significant improvement in sectors like agriculture and aqua culture in the state. For the first time, the concept of aqua retailing has also been introduced in the state.Subrata Mondal, chief general manager of the National Bank for Agriculture and Rural Development (NABARD) said one of the biggest problems the government has been facing is the fragmented land. The density of population in the state also affects the agricultural sector. Despite the challenges, the Bengal government has gone through significant improvement in the sector. Also Read – Rain batters Kolkata, cripples normal lifeNABARD extends financial assistance to the state government for its various rural projects. It has 31 regional offices and 2,000 consultancy centres for the better implementation of rural projects. It also provides funds for construction of rural roads and bridges in the state. NABARD plays a strong role in the rural and farming economy of the state. There are approximately more than 71 lakh families under the agriculture sector in the state. Bengal records the highest amount of paddy production and comes second highest in potato production. Emphasis is being laid on the development of sustainable aqua culture in order to prevent death Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedof fishes. “The population density and fragmented land are the major challenges for the state. Hence, we are advising banks for group mode finance for Bengal. It is the only state which has 100 percent financial support from NABARD in the cooperative sector. Agriculture can move forward by merging production and marketing together. To combat various issues related to climate change, four different funds have been generated in the country by NABARD out of which two projects are operational in Bengal,” Mondal said. What is most important here is that the average annual income of farmers in the state has gone up threefold in 2017-18 financial year than what it was seven years ago. According to Agriculture department sources, the average annual income of a farmer now stands at Rs 2,91,000 in 2017-18 financial year, while it stood at Rs 2,39,123 in 2016-17. During 2010-11, the average annual income of a farmer remained Rs 91,000. This has become possible due to various social schemes introduced by the Mamata Banerjee government to improve the socio-economic conditions of the farmers across the state. While the Centre aims at doubling the farmers’ income by 2022, the Bengal government has already increased the income level of farmers three times in the state. The present government has started distributing certified seeds to the farmers at 50 percent subsidised rates and also giving a platform to sell off their produce directly at various state government-managed outlets. No wonder that the food production in the state has gone up by a huge margin.last_img read more

KVIC generates employment in villages of Leh

first_imgFor the first time after Independence, Khadi seems to be exploring the remotest areas of the nation for providing the opportunities of employment to the villagers there.On September 18, Prime Minister Narendra Modi said at Varanasi that the nation is all set to make record production of honey like crops while distributing 500 bee-boxes there among 50 local farmers. The very next day of Prime Minister’s inspirational words, the Khadi and Village Industries Commission (KVIC) distributed 500 bee-boxes among tiger attack victims widows, SC/ST and other unemployed mass of sleepy Bali island under Sunderban of West Bengal and inaugurated ‘Tiger Victim Khadi Katai Kendra’ there, by providing 75 high-yield eight-spindle New Model Charkhas (NMCs). Khadi spinning training on NMCs to 75 women of the Bali Village has already been imparted and bee-keeping training to 50 candidates of this village has also been given through KVIC’s expert trainers. Also Read – Add new books to your shelfAfter four days, i.e. on September 22, the KVIC distributed 1750 bee-boxes among 175 tribal people in the remotest areas of Gujarat.On September 25, it was the turn of Kashmir’s Kraals (potters), who got a new lease of life as KVIC distributes one electric potter wheels, one set of pug mill, one set of blunger and one set of gas fired kiln to each group of 10 potters in altogether 160 beneficiaries in militancy-effected Pampore district of Jammu and Kashmir.

first_imgLondon: Scientists have decoded the physics behind a key chocolate-making process that gives the confectionary its distinctive smooth texture. The team from University of Edinburgh in the UK studied mixtures resembling liquid chocolate created using the conching process, which was developed by Swiss confectioner Rodolphe Lindt in 1879. Conching is a mixing process that evenly distributes cocoa butter within chocolate and may act as a “polisher” of the particles. Also Read – Add new books to your shelfIt promotes flavour development through frictional heat, release of volatiles and acids, and oxidation. The findings, published in Proceedings of the National Academy of Sciences, may hold the key to producing chocolate with lower fat content, and could help make chocolate manufacturing more energy efficient. The analysis, which involved measuring the density of mixtures and how they flow at various stages of the process, suggests conching may alter the physical properties of the microscopic sugar crystals and other granular ingredients of chocolate. Also Read – Over 2 hours screen time daily will make your kids impulsive”We hope our work can help reduce the amount of energy used in the conching process and lead to greener manufacturing of the world’s most popular confectionary product,” said Wilson Poon, a professor at the University of Edinburgh, who led the study. “By studying chocolate making, we have been able to gain new insights into the fundamental physics of how complex mixtures flow. This is a great example of how physics can build bridges between disciplines and sectors,” Poon said in a statement. Until now, the science behind the process was poorly understood, researchers said. The research shows that conching – which involves mixing ingredients for several hours – produces smooth molten chocolate by breaking down lumps of ingredients into finer grains and reducing friction between particles. Before the invention of conching, chocolate had a gritty texture. This is because the ingredients form rough, irregular clumps that do not flow smoothly when mixed with cocoa butter using other methods, the team said. Their insights could also help improve processes used in other sectors – such as ceramics manufacturing and cement production – that rely on the mixing of powders and liquids.last_img read more

Greg Cosell explains why Tom Savage is a huge upgrade over Brock

first_img Advertisement Cosell:New England’s defense is a week to week defense, which is part of Belichick’s genius. Their decision to play man or zone in a given week is opponent specific. From a personnel standpoint, they don’t have any impact players that opponents need to game plan around.They’ve become more multiple with their fronts, which compensates for their lack of a great pass rusher. They move people around and use different alignments to make up for a lack of impact players. They’ve become more versatile with their utilization and deployment of personnel.And the #Patriots are in the board with the SAFETY! 2 pts on FanDuel, and 2 pts vs. the #Ravens! #PatriotsDefense #BalvsNE #MNF— FanDuel (@FanDuel) December 13, 2016 Every week, Senior Producer of NFL Matchup and NFL Films, Greg Cosell, stops by the show to take the audience inside the Herd Film Room to break down the tape from the most talked about performances from the past week.Today, he’s breaking down the film from NFL Week 15.Roll the tape.The New England defense is highly rated, but doesn’t pass Colin’s eyeball test.  Does the film show they’re a top tier defense, or just middle of the pack?center_img Brock Osweiler was finally benched in Houston in favor of Tom Savage. Savage played well in his established a connection with DeAndre Hopkins. He looked a lot better than Osweiler has at any point this season, but that’s not saying much. What does the film say on Savage? Can he play? Or is he just better than below average Osweiler?Cosell:There’s always an overreaction when the back-up replaces the starter and plays well. Putting that aside, from a physical standpoint there’s no comparison between Savage and Osweiler. Savage has far better physical attributes, and he’s a naturally comfortable, polished and refined player in the pocket. He’s more of a prototype NFL quarterback.In the Jacksonville game, the wide receiver/corner matchup between DeAndre Hopkins and Jalen Ramsey was one of the better one’s of the year. Savage had no trouble turning it loose to Hopkins against Ramsey because he has the mindset of a prototypical quarterback. He throws to the one on one matchup. Troy Aikman once said if the receiver is one on one, you have to throw the ball. If the receivers don’t make plays, get better wide receivers.It’s likely that one of the reasons Osweiler was benched was because he played poorly with people around him. Savage is much more comfortable with people around him in a “noisy”, or “muddy” pocket, He didn’t break down his footwork or technique, and made some nice throws in a crowded pocket.Tom Savage is in.And Tom Savage is making plays. SWEET pass ? #JAXvsHOU— NFL (@NFL) December 18, 2016Tennessee is the most run-heavy team in the NFL. Is their reliance on the running game because the coaching staff believes that Mariota is best as a play action passer, or because they don’t think he would be as successful in a pass heavy offense? What does the film say about Mariota’s potential to be successful throwing more?Cosell:Tennessee’s run oriented offense is head coach is more a product of Mike Mularkey’s philosophy, not a product of catering to Mariota. It’s Cosell’s opinion that a  quarterback better develops when he works through a multi-dimensional offense. People laughed at their smash-mouth approach early in the year because they didn’t think a team could win like that in today’s NFL.They line up in 2 tight ends, 3 tight ends, they use a fullback. They want to play physical, power football and have the pass game work off the run game. It’s a throwback mindset, but it’s been effective. Within the offense, Mariota has improved almost every week. He’s an efficient player, and there’s a calmness and poise to his game. He’s very disciplined. He’s not a “high-level thrower”, but he’s improved his accuracy and ball placement since the season has progressed.TOUCHDOWN, @Titans! Marcus Mariota findet seinen Receiver in der Endzone!#INDvsTEN #touchdownnews— Pick 6 – News DE (@pick6deutsch) November 20, 2016Colin, and pretty much everyone else, missed on Dak Prescott. Dak has every quality Colin loves in a quarterback. His precision, accuracy, maturity, and reliability are all off the charts. He also limits mistakes. If he’s this good, how did everyone miss on Dak?Cosell:Dak has been far more accurate in the NFL than he was in college, which is incredibly rare. That’s one big reason people missed on him coming out in the draft. The Bucs were the perfect opponent for him to get back on track after several difficult weeks.The Giants defense gave him problems because they’re multiple, detailed, and nuanced with their fronts and their pressure schemes. Tampa had been playing well, but they run a Base 4-3, they don’t blitz, and predominantly play zone. This makes the reads more straightforward, but Dak made the throws. Prescott was able to mentally process quickly and threw the ball with great accuracy. It was a strong game for Dak.Dak Prescott keeps it and goes into the end zone untouched to put the #DallasCowboys up 17-3! #TBvsDAL #SNF— Chat Sports (@ChatSports) December 19, 2016Wide receiver Michael Floyd was released by the Cardinals and claimed by the Patriots after a DUI. Set aside the personal baggage, what does the film say about Floyd the player?Cosell:Floyd is a talented player. He’s a big target. Coming out in the draft, he was viewed as a prototypical X receiver, or the single receiver to the boundary that could win one on one matchups. He has size and speed, but has struggled to catch the ball. He’s had a down year from a production standpoint this season.Some receivers, like Chris Hogan, come into New England, pick up the system and play well. Others, like Chad Johnson, fail to pick up the system and wash out. There’s no telling which Floyd will be.Patriots WR Michael Floyd goes through the gauntlet during a ball-security drill in practice.— Mike Reiss (@MikeReiss) December 21, 2016last_img read more

Locating Steady Product Sources

first_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. 3 min read August 31, 2005 When you’d rather spend more time selling than searching forproducts, it’s time to consider more reliable sources ofmerchandise.No one can deny the thrill of posting a garage-sale find ordepartment-store clearance item on eBay and snagging 10 times whatyou paid for it or more. But you have to put up with thefeast-or-famine nature of sourcing your business this way. Now thatyou know how eBay works, you’re ready to take on the biggerdeals and larger volumes that will produce a steady stream ofproduct and establish you as a reliable seller among eBayshoppers.Wholesale distributors, liquidators, closeout distributors andjob-lot traders offer a virtually unlimited choice of product,though quality and quantity will vary. For access to thesesuppliers, you’ll need a state resale number, which allows youto buy wholesale anywhere in the country. Manufacturers andwholesalers may also set minimum orders, so you must first decidehow much merchandise you can afford to buy and store.Some wholesale distributors and manufacturers avoid internetbusinesses because they consider them unstable or unprofitable. Butaccording to Chris Malta, CEO of Worldwide BrandsInc., a product sourcing research publisher in Orlando,Florida, there is a subset of suppliers that tailor theirbusinesses to online sellers such as those on eBay. These”light bulk” wholesalers, as Worldwide Brands refers tothem, offer minimum orders of $500 or less.Locating a wholesale distributor who supplies what you want tosell isn’t always easy, but Sun W. Kim, 30, founder of TekGems Inc. (eBayUser ID: tekgems), found a novel way to do it. The San Franciscoelectronics entrepreneur did Google searches for the model numbersof products he wanted–searches that often led right todistributors’ websites. “Pretty soon, I knew who thedistributors were and whom to talk to,” Kim says.Now, it seems the manufacturers find him, using the sametechnique to check on their products. “I probably have asupplier or manufacturer interested in selling me something once aweek,” Kim says.Marsha Collier, an eBay PowerSeller and author of several booksabout eBay, recommends eBay itself as a product source. Usingsearch terms such as lot, case quantity, surplus or pallet, sellerscan find liquidated merchandise and closeouts from providers toobusy to sell the products individually. is also apopular source for finding these goods.Buying from liquidators offers a significant price benefit, butyou never know what you’ll get. “You’ll find goodbargains,” Malta says, “but you can also end up withitems taken from breakage piles.”Whom you buy from also depends on what you want to sell. Avoidproduct categories where oversupply has dropped prices too low toprovide a profit. Asad Haroon, general manager of, aWashington, DC-based search portal for the wholesale andsmall-business sectors, recommends buying merchandise related to ahot item. Instead of adding to the glut of cell phones, forexample, sell cell-phone plates or car adapters. “You may nothave as big a demand,” Haroon says, “but there won’tbe a lot of other people selling [them].”Whatever you sell, opt for items that will maintain yourinterest in the business. “If you hate the items you’reselling,” Collier says, “you’re really going to bebored.” Opinions expressed by Entrepreneur contributors are their own.

An Algae Serum Is Being Used to Treat Wounded Animals And Humans

first_img Register Now » 4 min read Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. Joe Landolina has always been a bit of a science nerd. Growing up he’d spend hours at his grandparents’ winery, finding plants in the vineyard and trying to see what he could extract from them. It was while he was tinkering with algae that the then 17-year-old discovered a liquid that would change into a solid quickly. “I always knew I wanted to go into medicine, so I thought of stopping a bullet wound [using that liquid].”Now 22, Landolina has started his own company called Suneris which makes Vetigel, a plant-based serum that, when applied to wounds, stops bleeding in seconds. It’s a product bigger than his initial aspirations. Joe Landolina of VetigelImage credit: Suneris”[Liquid bandage] doesn’t stop bleeding. It’ll seal the surface of a small cut but is not effective for traumatic bleeding.” Landolina says. “Vetigel makes a mechanical plug that holds the pressure in and also helps the body make its own clots.”Warning: the video below features heavy bleeding.Related: This MIT Grad Is Changing Medicine With a Needle-Covered PillWhile Landolina, along with his co-founder Isaac Miller and 25-person company, are still about a year away from being able to use its product on humans (if all goes well in the approval process), the entrepreneur has found an unexpected industry for Vetigel: animal health care. “Vets don’t have most of the tech that’s available to human patients,” Landolina says. He explains the standard of care for animals with traumatic bleeds is to use a gelatin sponge, but this method can take 10 minutes to staunch the bleeding, compared to seconds with Vetigel. This coupled with the fact that there are fewer federal regulations required to administer products to animals (as opposed to humans) has helped Suneris quickly break into the field.There are 3,500 veterinary clinics enrolled to use Vetigel once it’s distributed in the coming months. The company’s focus continues to be getting its product — retailing for $150 for five syringes — into the hands of surgeons, a high-use customer, as well as general practitioners (so they can begin do basic surgeries, rather than providing a referral to another doctor).Related: Bionic Eye Shows Promise for People With Age-Related Vision LossWith Vetigel’s current use and the possibility that it could one day be used on humans has caused a lot of interest among investors. The company has more than 60 investors, and they were easy to find. After Landolina hosted a Ted Talk (see below), Suneris had more interest than they could take on. “We had 1,200 accredited investors that asked to invest,” he says, adding that he and his team eventually asked potential backers to apply to be considered via a selection process. They whittled that batch of applications down to 40 (adding additional investors later on). Though Landolina wouldn’t give names, he says the backers are private individuals with high net worth, most of whom he had never met or had a connection to prior to investment. “We want someone who is not a VC, who’s passionate about the product, trusting of the team and has a network that’s beneficial,” he says. The funding Suneris has received is going toward research and development, along with focusing on the next step: getting FDA approval for human use. Everyone from military members to surgeons and emergency medical technicians could benefit from Vetigel’s abilities but that’s still a bit down the road. FDA approval for military and emergency use is expected within the next year or two and surgical use could be approved as soon as three years from now. To that end, the company is working on a new facility where they can work on researching, testing and manufacturing the version of Vetigel that would be used on people. Suneris hopes to find a suitable facility by early next year.For their launch event this summer, the backdrop was the Brooklyn Zoo. As vets and other guests filed in, a sea lion surfaced on a rock in his tank and barked. It was a happy sound, perhaps signaling approval.Related: Artificial Blood Transfusions Could Be a Reality By 2017 Opinions expressed by Entrepreneur contributors are their own.

Google Is No Longer Working on HighAltitude Drones

first_img This story originally appeared on PCMag January 12, 2017 Google has suspended research on its solar-powered drone, the company confirmed on Wednesday, less than three years after inheriting the project through its acquisition of Titan Aerospace.First reported by 9to5Google on Wednesday, the drone cancellation took place early in 2016, according to a representative from the X subsidiary of Google’s parent company, Alphabet. The representative told PCMag that X plans to refocus its efforts on development of a high-altitude balloon called Loon that can deliver internet access to remote areas, as well as the Project Wing drone delivery service.  “The team from Titan was brought into X in late 2015,” X Communications Manager Jacquelyn Miller wrote in an email to PCMag. “We ended our exploration of high altitude UAVs for internet access shortly after.”Miller explained that the decision to stop drone research was one of several reorganizations that occurred after Alphabet was established, but that X’s overall mission to expiriment with alternative ways of delivering Internet access hadn’t changed.”By comparison, at this stage the economics and technical feasibility of Project Loon present a much more promising way to connect rural and remote parts of the world,” she wrote. “Many people from the Titan team are now using their expertise as part of other high flying projects at X, including Loon and Project Wing.”The challenges of delivering Internet access via solar-powered drones have not deterred Facebook, which performed a test flight of its own Aquila drone last year. That flight ended in disaster, however, when the prototype crashed due to a structural failure.Facebook was also rumored to be interested in Titan Aerospace before Google acquired it in 2014. The company instead picked up UK-based Ascenta, which had also been working on solar-powered drones.

Yes Hackable Dolls and Insecure Fridges Really Are a Thing

first_imgNovember 15, 2018 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Opinions expressed by Entrepreneur contributors are their own. The premise of Bruce Schneier’s new book, Click Here to Kill Everybody, is that “the internet is powerful, but it is not safe. As ‘smart’ devices proliferate, the risks will get worse, unless we act now.” I couldn’t agree more.If you’ve seen Maximum Overdrive, Stephen King’s 1986 horror movie in which the world’s home appliances rise up and start attacking their owners, you’ll have a good idea of the kind of climate in which the Internet of Things (IoT) hacks are often talked about. Admittedly, the hacks detailed below are much more mundane, but if IoT security issues are not dealt with soon, King’s movie may not be so absurd after all.Related: The Dangers of the Internet of ThingsThere are serious security flaws that permeate the build process for IoT devices — security cameras to pacemakers, cars, home security devices and yes, potentially even your net-enabled fridge. However, as far as how those flaws can be exploited, it’s still relatively early to say. To date, the objective of IoT hacks appear to be either experimentation or the same as with any other kind of targeted hacking — to steal or otherwise manipulate data for financial gain or malicious intent. Here are some notable examples:In 2016, the IoT-driven Mirai virus perpetrated some of the largest DDoS attacks ever seen. A DDoS attack pointed at U.S.-based DNS provider Dyn, Mirai took down large parts of the internet, including Netflix and Amazon, and in a different attack, the country of Liberia, with an army of enslaved IP cameras, printers and baby monitors.Ransomware attacks on IoT devices underscore how critical the proper IoT security can be, especially when you consider that a smart device can be used as a jumping off point to hijack an entire network (and vice versa). U.K. hospitals were hit hard by last year’s WannaCry ransomware cyberattack, which cost the U.K.’s National Health Service almost £100m (despite its paltry $300 price tag for decrypting data) and led to the cancellation of 19,000 appointments. While the U.S. pretty much avoided the scope of the attack, there were some reports of U.S. hospitals being hit, including one hospital that had its radiology equipment hacked.For a peek into how clever criminals can be, we can look to the Mandalay Bay Casino hack, in which its high-roller database was stolen via a compromised, internet-connected fish tank thermometer. And security researchers have demonstrated how everything from Wi-fi-enabled Barbie Dolls to Samsung TVs can be hacked.The biggest issue with securing the IoT is that like the internet itself, the IoT ecosystem was not built with security in mind. All layers of the stack IoT — the hardware, software, etc., are vulnerable and inherently insecure across multiple fronts, and manufacturers are not yet incentivized through regulation or public pressure to change that.Related: Malware Hits Everyone, From Small Business to Big Government. What Are You Doing About It?Plus, implementing standards and best practices across a global, multi-pronged supply chain requires governments working in unison to create and enforce global standards. The global manufacturers who produce so many of the cheap, rushed-to-market IoT goods in countries prized for their cheap labor costs and low regulatory bar are not likely to start thinking about cybersecurity any time soon. At the consumer level, many are still clueless or uninterested about the weaknesses in their connected doorbells, and at worst, indifferent.The problems are massive, but Schneier spends almost half the book on how we can fix the problem. In short, he suggests a model consisting of technology and policy — a mix of well-crafted, enforceable government regulation and industry-wide adherence to strong security standards, such as those outlined by the National Institute of Standards and Technology (NIST).Schneier’s book is particularly timely in that is was published just as signs of change have begun to appear on the horizon. Six months ago, the European Union passed the General Data Protection Regulation (GDPR), which outlines very clear requirements for the use and handling of customer data. With a recent Facebook breach that impacted 3 million users, GDPR’s effectiveness will be soon be tested.In September 2018, California Governor Jerry Brown signed SB-327, the nation’s first IoT-specific law. The bill has been praised by some as a good first step and criticized by others as being too vague. Either way, it’s paving new ground. Plus, because it applies to devices built and sold in California, it will have ripple effects that extend beyond the state.Related: 12 Simple Things You Can Do to Be More Secure OnlineWe may not have to face down our own electric shavers as they try and cut our throats, but until security is baked into the manufacturing process for connected devices, we are leaving ourselves equally vulnerable. If I haven’t quelled your desire to use smart devices, here are some ways to do so as securely as possible: When evaluating products, ask salespeople questions about their security features. If they have nothing to say, or what they tell you is not easily understood, ask yourself — do you really need that cool new smart device?If you are using apps to control your IoT devices (think smart home alarms or thermostats), consider using a VPN for your phone that includes basic web protections. There are plenty of options, both free and for a small annual fee. Stay vigilant. any network-connected device can be hijacked, and phishing is still one of the most effective ways to deliver malware. Don’t assume your IoT devices are immune from email or web-based attacks accidentally unleashed on your smart devices from your laptop or desktop. 5 min read This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.

Firefox 48 Release Find out what is new

first_imgFirefox 48 Release: Find out what is new by Martin Brinkmann on August 01, 2016 in Firefox – Last Update: August 25, 2016 – 88 commentsFirefox 48 Stable will be released on August 2, 2016 according to the Firefox release schedule. Firefox 48 is a major release that makes add-on signing mandatory on Stable and Beta versions of the browser, and introduces multi-process functionality to the first batch of users (who don’t run any add-ons).Firefox 47.0.1 and earlier versions can be updated to Firefox 48. Additionally, updates for Firefox Beta, Developer, Nightly and Firefox ESR are released on August 2, 2016 as well.Firefox Beta is updated to 49.0, Firefox Developer to 50.0, Firefox Nightly to 51.0, and Firefox ESR to 45.3.Executive SummaryFirefox extension signing is enforced on Stable and Beta versions of Firefox. Users can no longer disable the requirement. Developer, Nightly, ESR and unbranded builds are provided that still ship with the functionality.About 1% of Firefox 48 users who don’t run add-ons will have the new multi-process architecture enabled for them.Support for Mac OSX 10.6, 10.7 and 10.8 ends. Firefox will continue to function on those platforms, but won’t receive new features or security updates anymore.Firefox 48 download and updateThe majority of Firefox users will receive 48 via the browser’s update mechanics. Firefox supports automatic updates but may also be configured for manual checks or no checks at all.Please note that the new version is released on August 2, 2016, and that it may not be available at the time of publication of this review.You may check for updates by tapping on the Alt-key on the keyboard, and selecting Help > About Firefox from the menu. This runs a manual check for updates, and displays the current version and channel.If Firefox is configured to download and install updates automatically, that is what is going to happen if the update is picked up. If not, you get options to download and install it manually instead.You may download all editions of Firefox using the links below instead.Firefox Stable downloadFirefox Beta downloadFirefox Developer downloadNightly downloadFirefox ESR downloadFirefox unbranded builds informationFirefox 48 ChangesAdd-on signing enforcementFirefox Stable and Beta users may no longer disable add-on signing in their versions of the browser. This blocks them from installing unsigned add-ons in Firefox. Unsigned add-ons are all add-ons that have not been submitted to Mozilla for signing.Firefox displays “This add-on could not be installed because it has not been verified” when you try to install an unsigned add-on in Stable or Beta versions of the browser.This means that it is no longer possible to install add-ons from third-party sources in Firefox, or old add-ons, if they have not been signed.There is no way around this other than switching to another Firefox channel that still offers a switch to turn the functionality off.Firefox Developer, Nightly, ESR and unbranded builds fall in that category.Multi-process Firefox roll outThe second major change is the roll out of multi-process Firefox. The feature separates content which, according to Mozilla, improves the browser’s stability, performance and security.About 1% of users who have not installed a single add-on in Firefox will get it in the beginning. Mozilla plans to increase the figure over time.Load about:support and check the “multiprocess windows” value to find out whether it is enabled in the browser.Check out our Firefox multi-process overview for additional details.Firefox Download Protection improvementsFirefox 48 ships with several changes designed to protect users better against unwanted or outright malicious downloads.First of all, Firefox 48’s Safe Browsing implementation supports the two new categories potentially unwanted software and uncommon downloads.The first warns Firefox users when they download executable files that may contain adware, the second when a file is not very popular.The change goes hand in hand with user interface changes. The download icon, displayed by default in the main Firefox toolbar, displays malicious downloads with a red exclamation mark, and potentially unwanted programs or uncommon applications with a yellow exclamation mark.That’s not all though. When you click on the download icon to display the last downloads, the default action for each download may either be open or remove.For potentially unwanted downloads and uncommon downloads, open is the default action indicated by a folder icon. For file downloads identified as malicious it is remove and indicated by an x-icon.Downloaded files are not opened or removed right away though. Firefox displays prompts that explain the risks of opening the file or allowing the download.The following three screenshots show the prompts for potentially unwanted, uncommon and malicious downloads in that order. Experienced users may override any of the prompts or warnings by right-clicking on files and selecting the “allow download” option. This is useful if a download is marked as problematic erroneously.Firefox users find more control over the download protection functionality under Security in the preferences.The new “block dangerous and deceptive content” preference is listed on about:preferences#security. You may turn the feature off completely there, or turn if off for dangerous downloads, or unwanted or uncommon downloads separately.Note: You may notice that the options to “block reported attack sites” and “block reported web forgeries” are no longer provided. While I have no confirmation yet, it appears that “block dangerous and deceptive content” fills that role now.Experienced users may control safe browsing on about:config or in a user.js file just like before:browser.safebrowsing.malware.enabled – Set this to false to block malware protection and unwanted downloads protection.Up to Firefox 49: browser.safebrowsing.enabled – This preference turns off phishing protection.From Firefox 50 on: browser.safebrowsing.phishing.enabled – Set this to false to turn off phishing protection.All Safe Browsing preferences are listed on the Mozilla Wiki.Other changesWindows: Tab (switch buttons) and Shift-F10 (pop-up menus) work now in customize mode.GNU/Linux: Better Canvas performance with Skia support.Media Parser developed using Rust and implemented in Firefox 48.Firefox 48 ships with a blocklist against plugin fingerprinting.The new “Get Add-ons” page launches in Firefox 48.Bookmark or open tab hits in Firefox’s address bar use “super smart icons” to let you know.Starting with Firefox 49, SSE2 CPU extensions are going to be required on Windows.Windows Remote Access Service modem Autodial is gone.Fixed WebRTC issues that Jabra & Logitech C920 webcam users experienced.WebExtensions support is considered stable. Yes, you may install (some) Google Chrome extensions in Firefox 48.Developer ChangesTemporary Add-on ReloadingAdd-on developers and users may load temporary add-ons in Firefox using the about:debugging page. This can be useful for add-on testing during development, or testing an add-on without installing it permanently in the browser.Any change made to a temporary loaded add-on required the browser to be restarted. This changes with Firefox 48, as it is now possible to reload extension that are temporarily loaded. (Bug 1246030)Firebug themeFirefox 48 ships with a new Developer theme. Besides dark and light variants, it is now also possible to load the Firebug theme which resembles the popular Firefox developer add-on.Firebug functionality is or will be integrated in Firefox natively, and the add-on itself won’t receive any more updates because of it.Other Developer changesDOM Inspector (Bug 1201475)Font Inspector enabled by default (Bug 128121)HTTP Log Inspection in Web Console (Bug 1211525)Improved CSS properties suggestions (Bug 1168246)Position of elements can be changed in content now (Bug 1139187)Check the resources section at the bottom of the article for links to full Developer change logs.Firefox for AndroidMaking Firefox the default browser is easier on Android 6 and upTo make Firefox the default on Android 6 Marshmallow and higher, do the following:Tap on Settings.Select Apps.Tap on the gear icon.Tap on Default Apps.Tap Browser app.Tap Firefox on the list.The previous process which is still valid for older Android versions required a lengthy process detailed here.Other Firefox 48 for Android changesAdd frequently visited sites to the home screen for faster access.Amazon product search suggestions now supported.Firefox 48 for Android users get control over web notifications.Firefox restores tabs by default.
