Polymer semiconductors, which can be processed on large-area and mechanically flexible substrates with low cost, are considered as one of the main components for future plastic electronics. However, they, especially n-type semiconducting polymers, currently lag behind inorganic counterparts in the charge carrier mobility - which characterizes how quickly charge carriers (electron) can move inside a semiconductor - and the chemical stability in ambient air.

University of Adelaide researchers have found that men who consume diets high in fat are more likely to feel sleepy during the day, to report sleep problems at night, and are also more likely to suffer from sleep apnea.

Cancer cells communicate with their environment through cell molecules that pass on signals to the inside of the cell. The signals help cancer cells multiply and migrate, spreading the disease. One strategy to fight cancer is with drugs that block the cell molecules that pass on the signals that lead to cancer growth. But cancer cells can quickly adapt to this tactic by ramping up the production of the blocked molecules. Baylor College of Medicine researchers are fighting cancer with a different approach. Instead of blocking messenger molecules, they accelerate their destruction.

Amsterdam, The Netherlands, 20 April 2016 - A new study being presented today at the 4th Workplace and Indoor Aerosols conference in Barcelona shows, for the first time, that exhaled e-cigarette particles are liquid droplets that evaporate within seconds. 

Ornithology journal The Condor: Ornithological Applications is publishing a Special Section of open access articles highlighting the impact that energy development is having on North America's bird populations.

PORTLAND, Ore., April 20, 2016 -- Depressed teenagers who received cognitive behavioral therapy in their primary care clinic recovered faster, and were also more likely to recover, than teens who did not receive the primary care-based counseling, according to a Kaiser Permanente study published today in the journal Pediatrics.

Researchers have discovered a link between the BRCA1 gene mutation and lower levels of a hormone that is an indicator of the number of eggs left in a woman's ovaries, according to research published today (Wednesday) in Human Reproduction [1], one of the world's leading reproductive medicine journals.

An intervention to reduce workplace sitting time has shown potential health benefits, in results published today in the International Journal of Epidemiology [1].

• Almost half of all drinking occasions are moderate, relaxed and take place in the home
• Pre-drinking is now a common feature of nights out for both younger and older adults
• Half of get-togethers with friends or family involve increased or higher risk drinking

New research into the UK's alcohol consumption has revealed a surprising picture of Britain's drinking culture.

New research on male Barbary macaques indicates that these primates have a flexible metabolic physiology, which help them survive by changing the speed of chemical reactions within their bodies, and consequently levels of energy, depending on temperature and availability of food.

The study also suggests that the metabolic rate of male macaques spikes dramatically during mating season, potentially providing a higher "aerobic capacity" at a point when males mate with multiple females a day, as well as fight other males for mating opportunities - on occasion to the death.

• GPS tool has pinpointed origin of Yiddish speakers
• Yiddish is thought to have been invented by Iranian and Ashkenazic Jews as they traded on the Silk Road
• Findings provide opposing theory to the view that Yiddish is an old German dialect

The origin of Yiddish, the millennium old language of Ashkenazic Jews, is something which linguists have questioned for decades.

Unless exposed to positive research experience and role models during their medical education and training, women are unlikely to consider careers in academic medicine seriously. That's one conclusion of an Oxford University study published in The Lancet. It asked why, when entry to medical schools is evenly split between men and women, those working in University medical departments are predominantly men.

The difficulty in subduing the pandemic strain of drug-resistant E. coli, called H30, may go beyond patient vulnerability or antibiotic resistance. This form of the disease-pathogen may have an intrinsic ability to cause persistent, harmful, even deadly infections.

RIVERSIDE, Calif. -- A survey of early-career scientists and environmental-science professionals found that only 11 percent felt their academic training alone provided the needed exposure to natural history, which can be defined as the observation of organisms in their natural environment.

TORONTO, APRIL 19, 2016 -- Breast cancer patients undergoing treatment with trastuzumab-containing regimens should be monitored for heart damage regardless of age. This is among the findings of a new study from the Peter Munk Cardiac Centre, the Institute for Clinical Evaluative Sciences (ICES) and the Ted Rogers Centre for Heart Research, University Health Network (UHN). The study was published yesterday in the Journal of Clinical Oncology.
