Nanostructure boosts stability of organic thin-film transistors



Posted: 12 Jan 2018 12:12 PM PST


A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric and protects the organic semiconductor - which had previously been vulnerable to damage from the ambient environment.


Surprising discovery could lead to better batteries



Posted: 12 Jan 2018 12:12 PM PST


Scientists have observed the concentration of lithium inside individual nanoparticles reverse at a certain point, instead of constantly increasing. This discovery is a major step toward improving the battery life of consumer electronics.


Past exposures shape immune response in pediatric acute respiratory infections



Posted: 12 Jan 2018 12:12 PM PST


By analyzing immune cells of children who came to the emergency department with flu symptoms, researchers found that the suite of genes these early-response cells expressed was shaped by factors such as age and previous exposures to viruses. Better understanding how early infections influence long-term immune response has implications for the diagnosis and treatment of young patients who suffer from acute respiratory tract infections.


New antifungal provides hope in fight against superbugs



Posted: 12 Jan 2018 10:29 AM PST


Microscopic yeast have been wreaking havoc in hospitals around the world -- creeping into catheters, ventilator tubes, and IV lines -- and causing deadly invasive infection. One culprit species, Candida auris, is resistant to many antifungals, meaning once a person is infected, there are limited treatment options. But researchers have now confirmed a new drug compound kills drug-resistant C. auris, both in the laboratory and in a mouse model that mimics human infection.


Scarring molecule in fat tissue links obesity with distressed fat



Posted: 12 Jan 2018 10:29 AM PST

The combination of two proteins exerts a regenerating effect in Parkinson's disease



Posted: 12 Jan 2018 10:29 AM PST


Current therapies for Parkinson's disease are mainly of a replacement type and pose problems in the long term, so the challenge is to establish an early diagnosis and develop neuroprotective and neurorestorative therapies that will allow the symptoms of the disease to be slowed down or even reversed. Researcher have now documented the regenerative, neuroprotective effect of two neurotrophic factors when they are applied in a combined way.


Expert unlocks mechanics of how snakes move in a straight line

Can Muesli help against arthritis?



Posted: 12 Jan 2018 10:27 AM PST


It is well known that healthy eating increases our general sense of wellbeing. Researchers have now discovered that a fiber-rich diet can have a positive influence on chronic inflammatory joint diseases, leading to stronger bones.


Genetic analysis can improve depression therapy



Posted: 12 Jan 2018 07:51 AM PST


The failure of SSRI antidepressants can be a result of genetic variations in patients. Variations within the gene that encodes the CYP2C19 enzyme results in extreme differences in the levels of escitalopram achieved in patients, according to a new study. Prescribing the dose of escitalopram based on a patient's specific genetic constitution would greatly improve therapeutic outcomes.


Thinking outside the box on climate mitigation



Posted: 12 Jan 2018 07:51 AM PST


A new article lays the groundwork for alternative climate mitigation scenarios that place less reliance on unproven negative emissions technologies in the future.


Species identification in the water bottle



Posted: 12 Jan 2018 07:51 AM PST


Environmental DNA analysis makes it possible to detect water organisms without having to capture them first. For the first time, researchers systematically investigated the effect of various environmental factors on environmental DNA analyses. By doing so, the researchers have made an important step towards the standardized application of this method for the monitoring of water bodies.

Black hole spin cranks-up radio volume



Posted: 12 Jan 2018 06:59 AM PST


Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.

Posted: 12 Jan 2018 06:12 AM PST


New research has demonstrated that an enzyme she had previously identified as playing a role in peripheral neuropathy induced by cancer chemotherapy also plays a role in peripheral neuropathy caused by diabetes. The significance of the identification of a common molecular mechanism is that the drug candidates she identified to treat chemotherapy-induced peripheral neuropathy could potentially be used to treat peripheral neuropathy caused by diabetes as well.
