Artificial synapse for neural networks

22/02/2017

For all the improvements in computer technology over the years, we still struggle to recreate the low-energy, elegant processing of the human brain. Now, researchers at Stanford University and Sandia National Laboratories have made an advance that could help computers mimic one piece of the brain's efficient design - an artificial version of the space over which neurons communicate, a synapse.

Switched-on DNA to spark nano-electronic applications

22/02/2017

Much like flipping your light switch at home - only on a scale 1,000 times smaller than a human hair - an ASU-led team has now developed the first controllable DNA switch to regulate the flow of electricity within a single, atomic-sized molecule.

Hard shell - healthy kernel

10/02/2017

Roasted and salted, ground as a baking ingredient or fresh from the shell - for all those who enjoy eating nuts, there is good news from nutritionists at Friedrich Schiller University Jena (Germany). Their latest research shows that nuts can inhibit the growth of cancer cells.

Faster way of detecting bacteria

08/02/2017

Brett Etchebarne, an assistant professor of emergency medicine in the College of Osteopathic Medicine at Michigan State University, has created a molecular diagnostic system that can identify dangerous bacteria such as E. coli, staph infections, and even some superbugs.

With mini-vessels, mini-brains expand research potential

03/02/2017

Scientists have recently made a wondrous variety of mini-brains - 3-D cultures of neural cells that model basic properties of living brains - but a new finding could add to the field's growing excitement in an entirely new "vein": Brown University's mini-brains now grow blood vessels, too.

Millions of people with metabolic syndrome may need more vitamin E

20/01/2017

New research has shown that people with metabolic syndrome need significantly more vitamin E - which could be a serious public health concern, in light of the millions of people who have this condition that's often related to obesity.

New type of monitoring: life of bacteria in microdroplets

12/01/2017

In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, since each of the hundreds and thousands of droplets moving through the microchannels can act as separate incubators.

Protein associated with Parkinson's travels from brain to gut

06/01/2017

Researchers of the German Center for Neurodegenerative Diseases (DZNE) have found that "alpha-synuclein", a protein involved in a series of neurological disorders including Parkinson's disease, is capable of travelling from brain to stomach and that it does so following a specific pathway. Donato Di Monte and co-workers report on this in the journal "Acta Neuropathologica".

Study shows blood products unaffected by drone trips

22/12/2016

In what is believed to be the first proof-of-concept study of its kind, Johns Hopkins researchers have determined that large bags of blood products, such as those transfused into patients every day, can maintain temperature and cellular integrity while transported by drones.

First steps to neutralizing Zika

28/11/2016

As Zika spreads throughout the world, the call for rapid development of therapeutics to treat Zika rings loud and clear. Taking a step further in identifying a possible therapeutic candidate, a team of researchers have discovered the mechanism by which C10, a human antibody previously identified to react with the Dengue virus, prevents Zika infection at a cellular level.
