Energy-efficient computing: Damping gives a faster switch

Tue, 04/18/2017 - 15:53
Controlling memory with electric fields enables faster and more energy-efficient computing.

Communicating tsunami evacuations effectively

Tue, 04/18/2017 - 15:52
An effective communication approach incorporating computer simulations could help people find practical means to evacuate in the event of a tsunami.

Technology is great, but are we prepared for the consequences?

Tue, 04/18/2017 - 15:43
Dependence on technology is slowly eroding some of our core principles, according to an expert. It's impacting everything from fake news to texting while driving.

Understanding decisions: The power of combining psychology and economics

Tue, 04/18/2017 - 15:14
A new article shows how collaborations between psychologists and economists lead to better understanding of such decisions than either discipline can on its own.

Harnessing heat to power computers

Tue, 04/18/2017 - 13:45
Heat is commonly regarded as computing's mortal enemy. Two researchers, however, flipped the question of how to keep computers cool to how to use heat as an alternative energy source.

Pinning down fraudulent business listings on Google maps

Tue, 04/18/2017 - 13:45
A partnership between academic computer scientists and Google has allowed the search giant to reduce by 70 percent fraudulent business listings in Google Maps. The researchers worked together to analyze more than 100,000 fraudulent listings to determine how scammers had been able to avoid detection -- albeit for a limited amount of time -- and how they made money.

Motor neurons adjust to control tasks, new brain research reveals

Tue, 04/18/2017 - 13:43
Motor cortical neurons optimally adjust how they encode movements in a task-specific manner, new research reveals. The findings enhance our understanding of how the brain controls movement and have the potential to improve the performance and reliability of brain-machine interfaces, or neural prosthetics, that assist paralyzed patients and amputees.

Getting things done while you wait for WiFi

Mon, 04/17/2017 - 19:50
To help us make the most of idle moments, researchers have developed a series of apps called 'WaitSuite' that test you on vocabulary words during moments of waiting, like when you're waiting for an instant message or for your phone to connect to WiFi.

Creating time crystals

Mon, 04/17/2017 - 19:50
Researchers created a previously-only-theoretical time crystal using a small piece of diamond embedded with millions of atomic-scale impurities known as nitrogen-vacancy (NV) centers. They then used microwave pulses to 'kick' the system out of equilibrium, causing the NV center's spins to flip at precisely-timed intervals.

New battery coating could improve smart phones and electric vehicles

Mon, 04/17/2017 - 18:49
High performing lithium-ion batteries are a key component of laptops, smart phones, and electric vehicles. Currently, the anodes, or negative charged side of lithium ion batteries, are generally made with graphite or other carbon-based materials. Now a new discovery may help unravel a 40-year mystery and could greatly improve battery performance in electronic devices and electric vehicles

Researchers working toward indoor location detection

Mon, 04/17/2017 - 15:47
Computer scientists are mapping a new solution for interior navigational location detection by linking it to existing sensors in mobile devices.

Monitoring troubles of the heart

Mon, 04/17/2017 - 13:55
In the near future, researchers believe technology might be employed to help de-escalate any potential conflicts among couples. Researchers employed multi-modal ambulatory measures to develop a system in order to detect if conflict had occurred between a couple -- a sort of seismometer of the shakes, rattles and rolls in a relationship.

Think brain games make you smarter? Think again, researchers say

Mon, 04/17/2017 - 13:55
Brain games marketed by the billion-dollar brain-training industry don't improve cognition or help prevent age-related brain decline, new research finds.

Helping students learn by sketching

Mon, 04/17/2017 - 12:48
New software Sketch Worksheets analyzes and provides feedback on student sketches, helping them learn multiple subjects.

SAVI camera ditches long lens for distant images

Mon, 04/17/2017 - 12:48
A new camera platform has been introduced that uses laser 'speckle' patterns to capture high-resolution images from a distance without telescopic lenses.

Building a better model of human-automation interaction

Sat, 04/15/2017 - 22:21
People generally make decisions using two ways of thinking: They think consciously, deliberate for a while, and try to use logic to figure out what action to take – referred to as analytical cognition. Or people unconsciously recognize patterns in certain situations, get a "gut feeling," and take action based on that feeling; in other words, they use intuitive cognition.

Computers create recipe for two new magnetic materials

Sat, 04/15/2017 - 13:56
Material scientists have predicted and built two new magnetic materials, atom-by-atom, using high-throughput computational models. The success marks a new era for the large-scale design of new magnetic materials at unprecedented speed.

When it comes to your profile picture, let a stranger do the choosing

Fri, 04/14/2017 - 14:58
When trying to pick the most flattering pictures for online profiles, it may be best to let a stranger do the choosing, a study suggests.

25 is 'golden age' for the ability to make random choices

Thu, 04/13/2017 - 18:11
People's ability to make random choices or mimic a random process, such as coming up with hypothetical results for a series of coin flips, peaks around age 25, according to a study.

Biased bots: Human prejudices sneak into artificial intelligence systems

Thu, 04/13/2017 - 18:10
In debates over the future of artificial intelligence, many experts think of the new systems as coldly logical and objectively rational. But in a new study, researchers have demonstrated how machines can be reflections of us, their creators, in potentially problematic ways.
