Emotion-recognition among people with disorders such as Parkinson's disease or schizophrenia may be affected by changes in the levels dopamine in the brain, say researchers.

Modern anesthesia is one of the most important medical achievements. Whereas before, patients had to suffer hellish agonies during every operation, today anesthesia enables completely painless procedures. One feels nothing and can remember nothing afterwards. It is already known from electroencephalography (EEG) studies on patients that during anesthesia the brain is put into a deep sleep-like...

Scientists found that incorporating sugar units into polymers makes them more degradable when exposed to UV light.

Slashing emissions of carbon dioxide by itself isn't enough to prevent catastrophic global warming, a new study shows. But if we simultaneously also reduce emissions of methane and other often overlooked climate pollutants, we could cut the rate of global warming in half by 2050 and give the world a fighting chance.

New research illustrates neuromorphic technology is up to sixteen times more energy-efficient for large deep learning networks than other AI systems.

Researchers have developed an algorithmic planner that helps delegate tasks to humans and robots. The planner, 'Act, Delegate or Learn' (ADL), considers a list of tasks and decides how best to assign them. The researchers asked three questions: When should a robot act to complete a task? When should a task be delegated to a human? And when should a robot learn a new task?

Watching too much TV is associated with increased risk of coronary heart disease regardless of an individual's genetic makeup, say scientists. The researchers show that -- assuming a causal link -- 11% of cases of coronary heart disease could be prevented if people watched less than an hour of TV each day.

A research team reveals the reason behind hot and wet winters in northwest Russia from 2019/20 winter. Anthropogenic influence found to be the reason for widespread warming according to the CMIP6 data.

Researchers have boosted pioneering technology to show whether potential treatments are worth progressing into human trials, in a game-changing move that could dramatically reduce the high failure rates in drug discovery and development.

Mustelids are the most ecologically and taxonomically diverse family within the order Carnivora. From the tayra in the neotropics to the wolverine in the subarctic, they inhabit a variety of ecological niches and developed corresponding species-specific traits related to their diet, reproductive strategy and morphology. An international team of scientists conducted a comparative analysis of whole...

The desire for a son could mean Nepali mothers stop breastfeeding infant daughters sooner, says new research. Girls in Nepal are breastfed for fewer months than boys on average, with girls with older sisters but no brothers being the most disadvantaged, says the study. And this shorter breastfeeding time is linked to a greater risk of death for Nepali infants in the study.

Cystic fibrosis is a rare genetic disease which can cause very serious symptoms. In particular, patients suffer from chronic bacterial infections that can lead to respiratory failure. It is caused by mutations in the CFTR gene, which regulates water movement across the cell membrane. Consequently, mucus quality is altered, it is no longer capable of capturing undesirable bacteria and expelling...

We humans do better on land than under water -- also when it comes to our hearing. But now a new study shows that we actually have better underwater hearing than previously thought -- at certain frequencies we hear just as well as the seal.

A new study has discovered that 'crown-like structures' surrounding breast tumors in overweight and obese patients could hinder their response to therapy. The findings of this study could potentially be used to improve personalized treatment for patients with HER2+ overexpressed breast cancer.

Are women who have twins more fertile? While previous studies concluded they are, a detailed analysis of more than 100,000 births from pre-industrial Europe by an international team of scientists shows they are not.

Astronomers have found a previously overlooked treasure trove of massive black holes in dwarf galaxies. The newly discovered black holes offer a glimpse into the life story of the supermassive black hole at the center of our own Milky Way galaxy.

A study has found that while COVID-19 vaccination is effective in most cancer patients, the level of protection against COVID-19 infection, hospitalization and death offered by the vaccine is less than in the general population and vaccine effectiveness wanes more quickly.

Engineers now report selective breakdown of a particularly stubborn class of PFAS called fluorinated carboxylic acids (FCAs) by common microorganisms. Under anaerobic conditions, a carbon-carbon double bond is crucial for the shattering the ultra-strong carbon-fluorine bond by microbial communities. The resulting products could be relayed to other microorganisms for defluorination under in aerobic...

Researchers developed a low-cost gel film made of abundant materials that can pull drinkable water from the air in even the driest climates.

A computer-guided approach to design can propose more solutions and balance out human inexperience and design fixation.

Researchers have developed several new varieties of wheat that tolerate soils with higher salt concentrations. After having mutated a wheat variety from Bangladesh, they now have a wheat with seeds that weigh three times more and that germinate almost twice as often as the original variety.

Researchers have developed a trajectory-planning system for autonomous vehicles that enables them to travel from a starting point to a target location safely, even when there are many different uncertainties in the environment, such as unknown variations in the shapes, sizes, and locations of obstacles.

Life-threatening arrhythmias are more common on days with highly polluted air, according to new research.

A taste adaptation intervention lowers salt intake and increases enjoyment of a sodium restricted diet in patients with hypertension, according to a small study.
