A new electrolyte allows rechargeable batteries to operate well without growing dendrites, tiny pin-like fibers that short-circuit rechargeable batteries.
Planning and managing vegetation in urban area is complex, yet it can be seamlessly done using computerized tree inventory and Geographic Information System (GIS).
Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the scientists who created them.
In a new study, 221 college students participated in an online chat room in which they watched a fellow student get “bullied” right before their eyes. Only 10 percent of the students who noticed the abuse directly intervened, either by confronting the bully online or helping the victim.
The evolution of Parkinson's is monitored in real time through a new portable system, with results sent to the doctor to improve the prescription of medication, developers report.
In the wake of high a profile death, it is increasingly common to see mass public outpourings of grief on RIP Facebook pages. This article explores media coverage of death and its relation to public expression of grief via social media.
A new theoretical approach clarifies interactions between motor proteins and yields the discovery that both weak and strong forces influence how they keep a cell's transport system robust. The study suggests that the collective behavior of motor proteins like kinesins keeps cellular transport systems robust by favoring slow and steady over maximum movement.
Researchers have developed a new, low-cost method to build DNA nanotubes block by block -- a breakthrough that could help pave the way for scaffolds made from DNA strands to be used in applications such as optical and electronic devices or smart drug-delivery systems.
There is a significant risk to your privacy whenever you visit a health-related web page, some researchers warn. An analysis of over 80,000 such web pages shows that nine out of ten visits result in personal health information being leaked to third parties, including online advertisers and data brokers.
Scientists have succeeded in using a 3-D printed guide to help nerves damaged in traumatic incidents repair themselves. The team used the device to repair nerve damage in animal models and say the method could help treat many types of traumatic injury.
Researchers have developed a 'fever alarm armband,' a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. The flexible organic components developed for this device are well-suited to wearable devices that continuously monitor vital signs including temperature and heart rate for applications in healthcare settings.
By 2030, one in five Americans will be age 65 or older. To understand the role neighborhoods play in seniors' ability to 'age in place' -- living safely and independently in one's home of choice rather than in a healthcare facility -- researchers created a web application that speeds up researchers' data collection.
Researchers have made an advance in manufacturing molybdenum disulphide, a 2-D material that could compete with graphene for replacing silicon in next-generation electronics. By growing flakes of the material around 'seeds' of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.
New diagnostic tests are needed to make vaccination against bovine tuberculosis (bovine TB) viable and the number of false positives from these tests must be below 15 out of every 10,000 cattle tested, according to research.
A statistical technique that sorts out when changes to words’ pronunciations most likely occurred in the evolution of a language offers a renewed opportunity to trace words and languages back to their earliest common ancestor or ancestors.
To help solve growing problems with wireless bandwidth crowding and support the next generation of mobile technology, researchers are developing measurement tools for channels that are new for mobile communications and that could offer more than 1,000 times the bandwidth of today's cell phone systems.
Smartphones and tablets may hold the key to getting more nurses to diagnose patients with chronic health issues like obesity, smoking, and depression -- three of the leading causes of preventable death and disability.
Toyohashi Tech's researcher has succeeded in directly predicting sound radiating from a recorder for the first time all over the world. The calculations for this study took two weeks using about 100 nodes of supercomputers. The findings contribute to proposal of a new design of musical instrument easy-to-play or totally new musical instruments.
Computer chips' clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel. But the ways in which a chip carves up computations can make a big difference to performance.
Using virtual reality to misrepresent how far the neck is turned can actually change pain experiences in individuals who suffer from chronic neck pain, according to research.
