Researchers have developed a computational walking model that could help guide patients to their best possible recovery after a stroke.

DNA-evidence needs statistical back-up

Tue, 01/10/2017 - 17:10
How do forensic scientists deal with complex DNA-evidence found at crime scenes? A researcher has now developed new statistical models to analyze them.

Rise of personal technology in criminal proceedings poses risks to individuals' rights

Tue, 01/10/2017 - 14:46
Personal technology such as fitness trackers and smartphones have become common companions in our daily lives. But those same devices increasingly will be used in criminal proceedings to gather evidence of criminal activity by their owners, raising questions about individuals' rights that the legal system is not yet fully prepared to address, according to a new study.

What did Big Data find when it analysed 150 years of British history?

Tue, 01/10/2017 - 00:14
What could be learned about the world if you could read the news from over 100 local newspapers for a period of 150 years? This is what a team of Artificial Intelligence (AI) researchers have done, together with a social scientist and a historian, who had access to 150 years of British regional newspapers.

Newly proposed reference datasets improve weather satellite data quality

Tue, 01/10/2017 - 00:03
Researchers have proposed in-orbit reference datasets for calibrating weather satellites. A recent presentation demonstrated that using these references reduced errors in microwave and infrared weather satellites to fractions of a degree Celsius.

Computing science researchers are using automated geotagging models to put a place to online data and documents.

GaN-on-Silicon for scalable high electron mobility transistors

Mon, 01/09/2017 - 16:37
Scientists have advanced gallium nitride (GaN)-on-silicon transistor technology by optimizing the composition of the semiconductor layers that make up the device. The team created the high electron mobility transistor (HEMT) structure on a 200 mm silicon substrate with a process that will scale to larger industry-standard wafer sizes.

An ecological invasion mimics a drunken walk

Mon, 01/09/2017 - 15:49
A theory that uses the mathematics of a drunken walk describes ecological invasions better than waves, according to a new study.

How phishing scams thrive on overconfidence

Mon, 01/09/2017 - 14:26
A new study examines overconfidence in detecting phishing e-mails. According to the research, most people believe they're smarter than the criminals behind these schemes, which is why so many fall easily into a trap.

Thu, 01/05/2017 - 19:35
Researchers have created a stretchy transistor that can be elongated to twice its length with only minimal changes in its conductivity. The development is a valuable advancement for the field of wearable electronics.

Genomic data sharing is critical to improving genetic health care

Thu, 01/05/2017 - 18:38
A new position statement tackles the question of how to make sense of the massive amount of genetic information being generated for better patient care.

New apps designed to reduce depression, anxiety as easily as checking your phone

Thu, 01/05/2017 - 17:31
Now you can find help for depression and anxiety on your smartphone as quickly as finding a good sushi restaurant. A novel suite of 13 speedy mini-apps called IntelliCare significantly reduced depression and anxiety in study participants, who used the apps on their smartphones up to four times a day. The reductions of 50 percent in anxiety and depression are comparable to results expected in clinical practice using psychotherapy or with antidepressant medication.

Scientists learn how to ramp up microbes' ability to make memories

Thu, 01/05/2017 - 00:23
Researchers have identified a mutation that prompts bacterial cells to acquire genetic memories 100 times more frequently than they do naturally. This discovery provides a powerful research tool and could bring scientists one step closer to developing DNA-based data storage devices.

Implantable microrobots: Innovative manufacturing platform makes intricate biocompatible micromachines

Wed, 01/04/2017 - 19:57
Researchers have developed a way to manufacture microscale-sized machines from biomaterials that can safely be implanted in the body. Working with hydrogels, they have invented a new technique that stacks the soft material in layers to make devices that have three-dimensional, freely moving parts. The study demonstrates a fast manufacturing method they call “implantable microelectromechanical systems.”
