Older workers whose reasoning abilities no longer allow them to meet the demands of their jobs may be more likely to develop chronic health conditions and retire early, which may not be ideal for the employee or employer...

While solar and wind power are rapidly becoming cost-competitive with fossil fuels in areas with lots of sun and wind, they still can't provide the 24/7 power we've become used to. At present, that's not big a problem be...

The study is the first to put antibiotic biosynthesis and resistance into an evolutionary context. The findings will help to guide the future discovery of new antibiotics and antibiotic alternatives which are medicines t...

Both general and abdominal obesity were strongly associated with mortality among Mexican adults. Each 5 kg/m2 increase in BMI above 25 kg/m2 was associated with a 30 percent increase in mortality. These findings refute p...

A multi-institutional team reveals a previously unknown gut-brain connection that helps explain how those extra servings lead to weight gain.

In a finding that could shed light on tissue formation, wound healing and cancer spread, a new study shows that human cells follow the same rules as non-living particles to form fractal-like branching structures.

A large cohort study has revealed a common osteoporosis drug significantly decreases premature mortality risk, likely related to a reduction in bone loss.

Hookah waterpipe use has grown in popularity in recent years -- 1 in 5 college students in the U.S. and Europe have tried it -- but the practice could be more dangerous than other forms of smoking, according to a first-o...

Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures. But a research tea...

Scientists have found a way to make single-celled bacteria behave like stem cells, differentiating into genetically unique individuals as they divide.

The gut-infecting bacterium Clostridium difficile is evolving into two separate species, with one group highly adapted to spread in hospitals, according to new research.

Engineers have developed the thinnest optical device in the world -- a waveguide that is three layers of atoms thin. The work is a proof of concept for scaling down optical devices to sizes that are orders of magnitude s...

A robotic brace that supports the neck during its natural motion is the first device shown to dramatically assist ALS patients in holding their heads and actively supporting them during range of motion. The brace should ...

Brain-selective estrogen treatment improves the symptoms of Parkinson's disease in male mice, according to new research. These findings may help explain the sex differences in Parkinson's disease and could lead to estrog...

Physical manifestations of negative memories in the hippocampus could underlie cognitive symptoms of depression, according to new research.

Mosquitoes can harbor thousands of malaria-causing parasites in their bodies, yet while slurping blood from a victim, they transmit just a tiny fraction of them. In an effort to define precisely the location of the paras...

Through their complex array of natural compounds and phytochemicals, walnuts provide a multitude of health benefits. A new study says protection against ulcerative colitis may be on that list.

The discovery of the previously unknown mutation could lead to routine testing of individuals with a strong family history of pancreatic cancer to determine if they carry the mutation, occurring in the gene known as RABL...

Not a good mix: A researcher has found that adults who combine prescription opioids for severe pain and cannabis report elevated anxiety and depression symptoms, with no increased pain reduction.

A new study shows how the Alzheimer's disease allows toxins to pass through the blood-brain barrier, further harming neurons.

Resistance to two critical antibiotic types, one a 'drug of last resort' when all others fail against some 'superbugs,' are widely distributed in Southeast Asia, raising the risk of untreatable infections, say a team of ...
