Researchers from the University of British Columbia and McMaster University have developed what could be the bone implant material of the future: an airy, foamlike substance from plant cellulose that can be injected into the body and provide scaffolding for the growth of new bone.
Researchers have taken another small step towards deep space exploration, by testing a new silver- and ruthenium-based antimicrobial coating aboard the International Space Station (ISS). Published in Frontiers in Microbiology, their study shows that the AGXX® dramatically reduced the number of bacteria on contamination-prone surfaces -- and could help protect future astronauts beyond the moon and Mars.
A study into the effectiveness of disinfecting birds' nests, carried out by the University of Kent, has led to a breakthrough in the understanding of biosecuity measures for the endangered echo parakeet in Mauritius. The research team found that annual disinfection of parakeet nest sites prior to the breeding season, intended to reduce the spread of infectious disease in endangered parrot species, didn't have the impact conservationists expected leading to recommendation for a different approach.
An EPFL study has showed that until now, scientists have been substantially underestimating how quickly gases are exchanged between mountain streams and the atmosphere. Based on research in the Swiss cantons of Vaud and Valais, an EPFL laboratory has shed new light on the role of mountain streams to emit greenhouse gases.
Inspired by jellyfish, NUS researchers have created an electronic skin that is transparent, stretchable, touch-sensitive, and repairs itself in both wet and dry conditions. The novel material has wide-ranging uses, from water-resistant touch screens to soft robots aimed at mimicking biological tissues.
Researchers at Rice University and the University of Texas Health Science Center at Houston develop a technique to grow custom-fit bone implants to repair jawbone injuries from a patient's own rib.
An interface system that uses augmented reality technology could help individuals with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a 'robot's eye view' of surroundings to help users interact with the world through the machine.
University of Cincinnati professor Jason Heikenfeld and his students have been creating new sensors on a wearable patch the size of a Band-Aid that stimulates sweat even when a patient is cool and resting. The sensor measures specific analytes over time that doctors can use to determine how the patient is responding to a drug treatment.
A new system for synthesizing quantum dots across the entire spectrum of visible light drastically reduces manufacturing costs, can be tuned on demand to any color and allows for real-time process monitoring to ensure quality control.
Ovarian cancer is often diagnosed too late for effective treatment. Israeli researchers are announcing a liquid biopsy-based diagnostic protocol for ovarian cancer, with higher sensitivity than previous approaches, that may help women in high-risk populations.
