Trees go high-tech: Process turns cellulose into energy storage devices

Posted: 07 Apr 2014 10:10 AM PDT

A fundamental chemical discovery should allow tress to soon play a major role in making high-tech energy storage devices. A method has been discovered to turn cellulose -- the most abundant organic polymer on Earth and a key component of trees –- into the building blocks for supercapacitors.

Personal touch signature makes mobile devices more secure

Posted: 07 Apr 2014 10:09 AM PDT

Researchers have developed a new security system that continuously monitors how a user taps and swipes a mobile device. If the movements don't match the owner's tendencies, the system recognizes the differences and can be programmed to lock the device.

'I can haz blood?' The surprising world of pet blood transfusions

Posted: 07 Apr 2014 09:25 AM PDT

Don Juan, Napoleon, Gucci, Azur, and Marissa are very friendly and will rush to welcome anyone who enters their room, and that's what makes them good blood donors. "I chose them for their hematological characteristics, but also for their good disposition. We didn't want cats that would be stressed when handled or that needed excessive sedation," said Dr. Marie-Claude Blais, Professor at the University of Montreal's Faculty of Veterinary Medicine. Where they are housed, the five cats (four males and one female) can climb to the top of their trapeze and out into the yard through a cat flap. They can lounge on a hammock all day long or play cat and mouse. What is more, the door to their room is never locked, so they can get their daily dose of hugs, a benefit not necessarily stipulated in their contract.

Social circuits that track how we like people, ideas

Posted: 07 Apr 2014 08:33 AM PDT

Whether at the office, dorm, PTA meeting, or any other social setting, we all know intuitively who the popular people are even if we can't always put our finger on why. That information is often critical to professional or social success. Yet until now, scientists have not understood how our brains recognize these popular people. In new work, researchers say that we track people's popularity largely through the brain region involved in anticipating rewards.

Rage-quitting: Feelings of failure, not violent content, foster aggression in video gamers

Posted: 07 Apr 2014 08:31 AM PDT

The disturbing imagery or violent storylines of videos games like World of Warcraft or Grand Theft Auto are often accused of fostering feelings of aggression in players. But a new study shows hostile behavior is linked to gamers' experiences of failure and frustration during play—not to a game's violent content.

Procrastination and impulsivity genetically linked: Exploring the genetics of 'I'll do it tomorrow'

Posted: 07 Apr 2014 07:17 AM PDT

Procrastination and impulsivity are genetically linked, suggesting that the two traits stem from similar evolutionary origins, according to new research. The research indicates that the traits are related to our ability to successfully pursue and juggle goals.

Twitter use linked to infidelity and divorce

Posted: 07 Apr 2014 07:17 AM PDT

Scientists found that active Twitter users are far more likely to experience Twitter–related conflict with their romantic partners. However, new research shows that Twitter use could actually be damaging to users' romantic relationships. Scientists found that active Twitter users are far more likely to experience Twitter-related conflict with their romantic partners.

Movies synchronize brains: Brain activity patterns show remarkable similarities across different people

Posted: 07 Apr 2014 06:06 AM PDT

When we watch a movie, our brains react to it immediately in a way similar to brains of other people. Researchers have succeeded in developing a method fast enough to observe immediate changes in the function of the brain even when watching a movie.

A bird? A plane? Or both? Bio-inspired unmanned aircraft capable of soaring like birds

Posted: 07 Apr 2014 06:03 AM PDT

Researchers are developing a bio-inspired unmanned aircraft capable of soaring like birds, boosting energy efficiency and endurance. The research team is aiming to be the first in the world to demonstrate an autonomous unmanned aircraft that can mimic birds by using updrafts around buildings to stay airborne.

Smoking visibility mapped for the first time

Posted: 06 Apr 2014 01:24 PM PDT

The visibility of smoking in city streets has for the first time anywhere been mapped by scientists. The methods developed through this research will help policymakers demonstrate the visibility of smoking in different areas, and provide scientific evidence for local authorities to advance smokefree outdoor policies.

Tracking the transition of early-universe quark soup to matter-as-we-know-it

Posted: 04 Apr 2014 10:58 AM PDT

By smashing together ordinary atomic nuclei at the Relativistic Heavy Ion Collider, scientists recreate the primordial soup of the early universe thousands of times per second. Using sophisticated detectors to track what happens as exotic particles emerge from the collision zone and "freeze out" into more familiar forms of matter, they are turning up interesting details about how the transition takes place.

Mountain climbing without the headaches

Posted: 04 Apr 2014 05:56 AM PDT

By monitoring blood flow in the brains of six climbers scaling Mount Kilimanjaro in Tanzania, German medical researchers have identified a possible way to prevent the headaches that are a common feature of altitude sickness.

Will this sentence be understood? What would be the best slogan?

Posted: 02 Apr 2014 06:52 AM PDT

An automated method that allows readers to understand the degree of difficulty of any individual sentence has been developed by researchers. This is the first technique of these characteristics, since the ones used so far only work for full documents.
