Finding ways to fix the climate before it is too late

Wed, 01/18/2017 - 13:26
Scientists and policymakers rely on complex computer simulations called Integrated Assessment Models to figure out how to address climate change. But these models need tinkering to make them more accurate.

Birds of a feather flock together to confuse potential predators

Wed, 01/18/2017 - 00:26
Scientists have created a computer game style experiment which sheds new light on the reasons why starlings flock in massive swirling groups over wintering grounds.

4G network infrastructure could mean fewer accidents by drivers

Tue, 01/17/2017 - 19:01
A pre-existing 4G network infrastructure could help drivers make safe decisions in or near accidents, according to new research.

Study applies game theory to genomic privacy

Tue, 01/17/2017 - 19:01
A new study presents an unorthodox approach to protect the privacy of genomic data, showing how optimal trade-offs between privacy risk and scientific utility can be struck as genomic data are released for research. The framework can be used to suppress just enough genomic data to persuade would-be snoops that their best privacy attacks will be unprofitable.

Why scientists should research emojis and emoticons :-P

Tue, 01/17/2017 - 19:01
More than 90 percent of online populations now incorporate emojis and emoticons into their texts and emails, and researchers are wondering what the use of (~_^), (>_<), or =D can reveal about human behavior. Emojis and emoticons can be used as tools for evaluating how we relate to each other in the digital age.

Crowdfunding expands innovation financing to underserved regions

Tue, 01/17/2017 - 18:57
Crowdfunding platforms, such as Kickstarter, have opened a funding spigot to startups in regions that have suffered from a venture capital drought, a new study shows.

Protein research: the computer as microscope

Mon, 01/16/2017 - 14:16
Using a combination of infrared spectroscopy and computer simulation, researchers have gained new insights into the workings of protein switches. With high temporal and spatial resolution, they verified that a magnesium atom contributes significantly to switching the so-called G-proteins on and off.

Computational modeling reveals anatomical distribution of drag on downhill skiers

Mon, 01/16/2017 - 14:14
Minimizing air resistance and friction with snow is key to elite performance in downhill skiing. Experiments in wind tunnels have revealed the total drag experienced by skiers, but have not provided precise data on which parts of the body cause the most air resistance when adopting the full-tuck position.

One in five young people lose sleep over social media

Mon, 01/16/2017 - 14:14
One in five young people regularly wake up in the night to send or check messages on social media, according to new research. This night-time activity is making teenagers three times more likely to feel constantly tired at school than their peers who do not log on at night, and could be affecting their happiness and wellbeing.

The importance of beating buffering

Sun, 01/15/2017 - 00:11
Streaming video over mobile networks could be greatly improved by smart prioritization of visually important data, report investigators.

Teens unlikely to be harmed by moderate digital screen use

Fri, 01/13/2017 - 13:59
Parents and pediatricians alike may worry about the effects of teens' screen time, but new findings from over 120,000 adolescents in the UK indicate that the relationship between screen time and well-being is weak at best, even at high levels of digital engagement.

Vader systems creates liquid metal 3-D printer for manufacturing

Thu, 01/12/2017 - 21:21
A father and son team have created a liquid metal 3-D printing machine that could represent a significant transformation in manufacturing. The machine is so novel it represents a quantum leap in the ability to print three-dimensional objects in metal. Other metal printers exist, but most use a process of laying down powered metal and melting it with a laser or electron beam.

Malaria elimination: Vaccines should be tested on larger groups of volunteers

Thu, 01/12/2017 - 19:12
To find an effective vaccine against malaria it is crucial to test candidate vaccines on larger groups of people than previously thought -- according to a new study. Researchers developed a mathematical model to determine the minimum number of people required for a good vaccine trial.

Classic video game system used to improve understanding of the brain

Thu, 01/12/2017 - 19:12
The complexity of neural networks makes them difficult to analyze, but humanmade computing systems should be simpler to understand. Researchers have now applied widely used neuroscience approaches to analyze the classic games console Atari 2600 -- which runs the video game 'Donkey Kong' -- and found that such approaches do not meaningfully describe how the console's microprocessor really works.

Wearable biosensors can flag illness, Lyme disease, risk for diabetes; low airplane oxygen

Thu, 01/12/2017 - 19:11
Can your smart watch detect when you are becoming sick? A new study indicates that this is possible. By following 60 people through their everyday lives, researchers found that smart watches and other personal biosensor devices can help flag when people have colds and even signal the onset of complex conditions like Lyme disease and diabetes.

Training computers to differentiate between people with the same name

Thu, 01/12/2017 - 16:07
How do you tell which Anna Hernandez authored a specific study or which Robert Jones is attempting to board an airplane flight? New researchers have developed a novel-machine learning method to provide better solutions to the perplexing problem of name disambiguation.

In teens, strong friendships may mitigate depression associated with excessive video gaming

Thu, 01/12/2017 - 16:00
Teenagers who play video games for more than four hours a day suffer from symptoms of depression, but frequent use of social media and instant messaging may mitigate symptoms of game addiction in these teens, new research suggests.

Instagram documents rising hookah use

Thu, 01/12/2017 - 13:56
Social media is giving researchers insight into the rising use of hookah, according to a study. Hookah, smoked through a water pipe and also known as shisha, has harmful health effects similar to cigarettes. But as cigarette use declined between 2005 and 2015 in the US, hookah use increased. New data from social media documents thousands of people using hookah in social settings and nightlife establishments using social media to promote hookah use.

Trust issues: Users more gullible when they customize their technology

Wed, 01/11/2017 - 20:18
Cheery robots may give people the creeps and serious robots may actually ease anxiety depending on how users perceive the robot's role in their lives, according to an international team of researchers.

New laser based on unusual physics phenomenon could improve telecommunications, computing

Wed, 01/11/2017 - 18:27
Researchers have demonstrated the world's first laser based on an unconventional wave physics phenomenon called bound states in the continuum. The technology could revolutionize the development of surface lasers, making them more compact and energy-efficient for communications and computing applications. The new BIC lasers could also be developed as high-power lasers for industrial and defense applications.
