15 percent of sixth-grade students commit cyber abuse

Thu, 10/13/2016 - 15:15
Fifteen percent of sixth-grade students reported they had perpetrated at least one form of abuse toward a dating partner through technology, according to a new study.

Strongest coupling between light and matter ever achieved

Wed, 10/12/2016 - 22:38
Researchers have recorded an interaction between light and matter 10 times larger than previously seen. The strength of the interaction between photons and a qubit was so large that it opens the door to a realm of physics and applications unattainable until now.

Ultra-thin ferroelectric material for next-generation electronics

Wed, 10/12/2016 - 17:40
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Soft robots that mimic human muscles

Wed, 10/12/2016 - 17:31
Robots are usually expected to be rigid, fast and efficient. But researchers have turned that notion on its head with their soft robots.

Just give me some privacy

Wed, 10/12/2016 - 17:22
Not everyone who strives to navigate the internet without being tracked is up to no good. This is the underlying premise of a qualitative study led by researchers who gathered the stories of people working on collaborative projects online -- like editing Wikipedia -- and are concerned about their privacy and taking steps to protect it.

In the fight against Alzheimer's, online gamers can now get in on the action

Wed, 10/12/2016 - 16:12
Researchers behind a new online game are inviting members of the public to look under a virtual microscope and contribute directly to Alzheimer's disease research.

Encrypting medical photos with chaos

Tue, 10/11/2016 - 16:57
Chaos and confusion could be used to encrypt color photos and protect them from prying eyes, according to computer scientists in Algeria. Writing in a new article, the team describes a new algorithm that generates pseudo-random sequences that change a plain image into a ciphered image in a single step leading to a file that cannot be cracked.

Major racial bias found in leading genomics databases

Tue, 10/11/2016 - 13:01
Researchers have confirmed for the first time that two of the top genomic databases, which are in wide use today by clinical geneticists, reflect a measurable bias toward genetic data based on European ancestry over that of African ancestry.

New 3D design for mobile microbatteries

Tue, 10/11/2016 - 12:59
In the race towards miniaturization, a research team has succeeded in improving the energy density of a rechargeable battery without increasing its size (limited to a few square millimeters in mobile sensors). This feat was achieved by developing a 3D structure made of microtubes, the first step towards producing a complete microbattery. The first experiments have demonstrated the excellent conductivity of the battery's solid electrolyte, report scientists.

Typing while driving could be more safe with simple text entry technique

Tue, 10/11/2016 - 12:59
A combination of a head-up display and the keypad familiar to us from mobiles in the 2000s significantly improved the performance of drivers who were texting while driving.

Dangerous drug interactions uncovered with data science

Mon, 10/10/2016 - 18:25
Safe when taken on their own, some prescription drugs become deadly when combined. Many of these interactions are well known, but others remain hidden to doctors, drug companies, and patients. Identifying these risky combinations has become a priority as the number of Americans on multiple medications rises. Now a new potentially dangerous drug interaction has been uncovered using data science.

Docs much bettter than internet or app-based symptoms checkers

Mon, 10/10/2016 - 16:01
Hundreds of millions of people rely on Internet or app-based symptom checkers to help make sense of symptoms or self-diagnose diseases. The first direct comparison shows human doctors outperform digital ones in diagnostic accuracy.

Brain-inspired device to power artificial systems

Fri, 10/07/2016 - 12:47
New research has demonstrated that a nanoscale device, called a memristor, could be used to power artificial systems that can mimic the human brain. Artificial neural networks (ANNs) exhibit learning abilities and can perform tasks which are difficult for conventional computing systems, such as pattern recognition, on-line learning and classification. Practical ANN implementations are currently hampered by the lack of efficient hardware synapses; a key component that every ANN requires in large numbers.

Smallest. Transistor. Ever.

Thu, 10/06/2016 - 18:05
Engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. Now, a team of researchers has succeeded in creating a transistor with a working 1-nanometer gate. For comparison, a strand of human hair is about 50,000 nanometers thick.

Small droplets feel the vibe

Thu, 10/06/2016 - 16:15
A team of researchers have used ultrasonic forces to accurately pattern thousands of microscopic water-based droplets. Each droplet can be designed to perform a biochemical experiment, which could pave the way for highly efficient lab-on-a-chip devices with future applications in drug discovery and clinical diagnostics.

Computer experts identify fourteen themes of creativity

Thu, 10/06/2016 - 14:34
The elusive and complex components of creativity have been identified by computer experts.

Online emancipation: Protecting users from algorithmic bias

Thu, 10/06/2016 - 14:14
To establish a system of auditability and build trust and transparency when it comes to internet use, researchers want to learn more about the concerns and perspectives of internet users with the aim of drawing up policy recommendations, ethical guidelines and a ‘fairness toolkit’.

'Virtual physiotherapist' helps paralyzed patients exercise using computer games

Wed, 10/05/2016 - 18:08
A simple device can improve the ability of patients with arm disability to play physiotherapy-like computer games, according to new research. 

3-D-printed robots with shock-absorbing skins

Wed, 10/05/2016 - 17:07
Anyone who's watched drone videos or an episode of "BattleBots" knows that robots can break -- and often it's because they don't have the proper padding to protect themselves.
