New batteries with better performance and improved safety

Phones, laptops, electric cars - batteries are everywhere. And to meet the expectations of today's consumers, these batteries are increasingly light, more powerful and designed to last longer. Currently the most important technologyShow More Summary

When traveling on public transport, you may want to cover your ears

The noise levels commuters are exposed to while using public transport or while biking, could induce hearing loss if experienced repeatedly and over long periods of time, according to a study published in the open access Journal of Otolaryngology - Head & Neck Surgery. Show More Summary

The future of sutures and staples: A sealant inspired by slugs

Although sutures and staples have been used for decades to close wounds or surgical incisions, both have their drawbacks: suturing can be time-consuming and can lead to extended and costly procedures, while staples are limited to use during open procedures and can cause tissue damage upon insertion, which can lead to infection.

Glucocorticoids offer long-term benefits for patients with Duchenne muscular dystrophy

WASHINGTON--(Nov. 22, 2017)--Glucocorticoids, a class of steroid hormone medications often prescribed to patients with Duchenne muscular dystrophy (DMD), offer long-term benefits for this disease, including longer preservation of muscle strength and function and decreased risk of death.

Moderate coffee drinking 'more likely to benefit health than to harm it' say experts

Drinking coffee is "more likely to benefit health than to harm it" for a range of health outcomes, say researchers in The BMJ today. They bring together evidence from over 200 studies and find that drinking three to four cups of coffee a day is associated with a lower risk of death and getting heart disease compared with drinking no coffee.

GP online consultations: Not the panacea policy makers are hoping for

Online GP consultation systems may not be the silver bullet for reducing GP workload and patient waiting times that government policymakers are hoping for, NIHR-funded research from the University of Bristol has found. These systemsShow More Summary

Research points to diagnostic test for top cause of liver transplant in kids

CINCINNATI - Biliary atresia is the most common cause of liver transplants for children in the United States. Now researchers report in Science Translational Medicine finding a strong biomarker candidate that could be used for earlier diagnosis and lifesaving treatments, possibly avoiding more invasive procedures like liver transplant.

New approach to tracking how deadly 'superbugs' travel could slow their spread

ANN ARBOR, Mich. -- Killer bacteria - ones that have out-evolved our best antibiotics -- may not go away anytime soon. But a new approach to tracking their spread could eventually give us a fighting chance to keep their death toll down. Using...Show More Summary

Researchers find infectious prions in Creutzfeldt-Jakob disease patient skin

Creutzfeldt-Jakob disease (CJD)--the human equivalent of mad cow disease--is caused by rogue, misfolded protein aggregates termed prions, which are infectious and cause fatal damages in the patient's brain. CJD patients develop signature microscopic sponge-like holes in their brains. Show More Summary

Getting under the skin of prion disorders

Infectious prion proteins - the causative agents of the fatal neurodegenerative disorder Creutzfeldt-Jakob disease - can be detected in the skin of afflicted individuals, researchers now report. The findings raise the remote possibility that prion diseases may be transmitted through surgical procedures involving the skin. Show More Summary

Artificial lights increasing 'loss of night,' especially in some nations

Artificial Lights Increasing "Loss of Night," Especially in Some Nations: In a long-term, high-resolution global analysis of night light emissions, researchers report that the artificially lit surface of our planet is still growing - in both size and brightness - in most countries. In fewer countries has it stayed stable or declined, they say.

Bowhead whales come to Cumberland Sound in Nunavut to exfoliate

Aerial drone footage of bowhead whales in Canada's Arctic has revealed that the large mammals molt and use rocks to rub off dead skin. The footage provides one answer to the mystery of why whales return to Cumberland Sound, Nunavut,Show More Summary

Tiny robots step closer to treating hard-to-reach parts of the body

Tiny remotely operated robots could be designed to diagnose and treat illness in hard-to-reach areas of the human body, research suggests. In tests, a swarm of robots measuring a few millionths of a metre long - about the size of a blood...Show More Summary

NIH scientists and collaborators find prion protein in skin of CJD patients

National Institutes of Health (NIH) scientists and collaborators at Case Western Reserve University School of Medicine have detected abnormal prion protein in the skin of nearly two dozen people who died from Creutzfeldt-Jakob disease (CJD). The scientists also exposed a dozen healthy mice to skin extracts from two of the CJD patients, and all developed prion disease.

Hidden properties of solids

Berry curvature may not be the most well-known scientific concept, but to many physicists, its direct measurement is something akin to a holy grail. A powerful unifying principle in several branches of classical and quantum physics, Berry curvature is a strange and elusive quantum mechanical property of solids. Show More Summary

The brains of children with a better physical fitness possess a greater volume of gray matter

Researchers from the University of Granada (UGR) have proven, for the first time in history, that physical fitness in children may affect their brain structure, which in turn may have an influence on their academic performance. MoreShow More Summary

Preliminary stages of dementia reduce human face memorization ability

A Japanese research group has revealed that elderly people with mild cognitive impairment (MCI) have a particularly weakened ability to memorize human faces in the short term when compared to healthy elderly people. MCI patients also had a different gaze behavior when trying to memorize a face. This research may lead to the early detection of dementia.

Climate change models of bird impacts pass the test

A major study looking at changes in where UK birds have been found over the past 40 years has validated the latest climate change models being used to forecast impacts on birds and other animals. Led by the University of Adelaide, in...Show More Summary

A huge hydrogen generator at the Earth's core-mantle boundary

Splitting water into hydrogen and oxygen is a major theme in the development of clean, abundant energy source. A new study lead by an international research group revealed that when water meets the iron core of the Earth, the extremely...Show More Summary

Researchers discover specific tumor environment that triggers cells to metastasize

A team of bioengineers and bioinformaticians at the University of California San Diego have discovered how the environment surrounding a tumor can trigger metastatic behavior in cancer cells. Specifically, when tumor cells are confined in a dense environment, the researchers found that they turn on a specific set of genes and begin to form structures that resemble blood vessels.
