A biosensor detects adulteration of horse in beef meat within one hour (12/09/2017)
The
adulterating of beef with horse meat can now be detected with an electrochemical
biosensor developed by the Complutense University of Madrid, which is able to
recognize a DNA fragment that exists among 4500 mitochondrial genomes of
horses, and which is absent in other mammals.
Supercharging silicon batteries (09/09/2017)
Scientists
have designed a novel silicon-based anode to provide lithium batteries with
increased power and better stability.
Newly-discovered semiconductor dynamics may help improve energy efficiency (09/09/2017)
Researchers
examining the flow of electricity through semiconductors have uncovered another
reason these materials seem to lose their ability to carry a charge as they
become more densely 'doped.'
New tool for characterizing quantum simulators (08/09/2017)
Physicists
are developing quantum simulators, to help solve problems that are beyond the
reach of conventional computers. However, they first need new tools to ensure
that the simulators work properly. Researchers have now implemented a new
technique in the laboratory that can be used to efficiently characterize the
complex states of quantum simulators. The technique could become a new standard
tool for characterizing quantum simulators.
Robot learns to follow orders like Alexa (07/09/2017)
Computer scientists have developed an Alexa-like system that allows robots to understand a wide range of commands that require contextual knowledge about objects and their environments. They've dubbed the system 'ComText,' for 'commands in context.'
Accretion-powered pulsar reveals unique timing glitch (07/09/2017)
The discovery of the largest timing irregularity yet observed in a pulsar is the first confirmation that pulsars in binary systems exhibit the strange phenomenon known as a 'glitch.'
Tiny ultrasound-triggered sacs designed to relieve pain (07/09/2017)
Opioids may be an effective
means of post-operative pain relief, but they're also potentially addictive.
With this drawback in mind, scientists at Boston Children's Hospital have
developed a new pain management system that incorporates ultrasound and
liposomes (microscopic man-made sacs) full of a nerve-blocking agent.
Asthma medicine halves risk of Parkinson's (06/09/2017)
Using data gathered from 100 million Norwegian prescriptions, researchers have found that asthma medicine can halve a patient's risk of developing Parkinson´s disease.
Researchers devise a new way of producing hydrogen fuel (05/09/2017)
A U.S.-based team of researchers including MIPT scientists has assembled a nanoscale biological structure capable of producing hydrogen from water using light. They inserted a photosensitive protein into nanodiscs—circular fragments of cell membrane composed of a lipid bilayer—and enhanced the resulting structure with particles of titanium dioxide, a photocatalyst. The research findings were published in the journal ACS Nano.
'Learning database' speeds queries from hours to seconds (05/09/2017)
A
tool that makes large databases work smarter, not harder, could unlock the
potential of big data to drive medical research, inform business decisions and
speed up a slew of other applications that today are mired in a worldwide data
glut.
