A research team at Lund University in Sweden has conducted a study to
test the effectiveness of tomosynthesis breast screening against more
conventional mammograms. The results are promising, showing the new
technique to be better at detecting tumors, as well as being a more
comfortable experience for the patient.
In what it calls a "world first," Transport for London (TfL) will trial cyclist detection systems at traffic lights in the city with a view to improving cycle-flow. The technology aims to detect the number of cyclists travelling along a route. It then adjusts traffic signal timings to give cyclists more time on green lights.
At present, diagnosing malaria can be a difficult process involving powerful microscopes and careful scanning of blood samples for tiny parasites in a technique discovered in 1880. But a more accessible method may be in the works. A team of Australian scientists has discovered that certain chemicals are present and can be detected in the breath of sufferers, raising the possibility of a cheap breath test to diagnose the deadly disease.
A team of ESO astronomers working from the La Silla Observatory, Chile, has detected the first direct reflection of light from an exoplanet orbiting a Sun-like star. The exoplanet, 51 Pegasi b, is what is known as a hot Jupiter, a prevalent form of gas giant that sits much closer to its parent star than our own Jovian neighbor.
New software based on an algorithm developed in an open competition hosted by NASA improves the detection rate of potentially hazardous near-Earth asteroids. The software comes in the form of a free-to-download application, capable of being run from most laptops or desktops, transforming any amateur astronomer into a seasoned asteroid hunter.
As any classic murder mystery or spy thriller will tell you, cyanide is a poison that acts quickly. Once exposed to it, a person can die within 30 minutes. Unfortunately for people who think they might
have encountered it, the standard test for determining exposure takes 24 hours. Now, however, a scientist at South Dakota State University has developed a sensor that detects cyanide within a blood sample in just 70 seconds.
Point-of-care medical diagnostics technologies offer a fast and cheap way to help patients as they require no experienced personnel or expensive laboratory tests. Several innovations such as a DNA test chip
and a biosensor that can detect viruses
give us an idea of the possibilities in this field. Now a research team at the University of Rhode Island in the US has developed a paper-based platform that's claimed can perform complex diagnostics.
BAE Systems is in the process of developing and testing a next-generation radar system for the Eurofighter Typhoon. The Captor E-Scan, fitted in the nose-cone of the fighter, boasts a number of improvements over other Active Electronically Scanned Arrays (AESAs), including a wider field of regard and the provision of advanced electronic warfare protection.
Along with flame-retardant clothing
, flexible supercapitors
and a stronger alternative to carbon fiber
, carbon nanotubes may soon have yet another application. Led by Prof. Ling Zang, a team of researchers at the University of Utah has integrated the tiny tubes of carbon atoms into a prototype explosives sensor. It can also detect illegal drugs and toxic chemicals such as nerve gas, reportedly doing so better than currently-used technologies.
Vitamin B12 is vital to keep a nervous system healthy. Since it is found mainly in meat and dairy, it is common for people to associate B12 deficiency with vegans, who are aware of this issue (in Germany there's even a B12-enriched toothpaste
) and often take measures to supplement. In fact, it is the general population of developing countries who are more likely to lack B12, and it is primarily for them that a team of Canadian researchers has developed a simple, cheap B12 test kit.
