Scientists have discovered that a receptor on the surface of brain cells plays a key role in regulating how both animals and people respond to stress. The research suggests that the receptor may represent an important bi...

DNA changes throughout a person's life can significantly increase their susceptibility to heart conditions and other age-related diseases, research suggests.

People in 16 communities received usual care and those in 14 communities had an intervention that included the initiation and monitoring of treatments and controlling risk factors by non-physician health workers using co...

Excess phosphorus from fertilized cropland frequently finds its way into nearby rivers and lakes, resulting in a boom of aquatic plant growth, plunging oxygen levels in the water, fish die-offs and other harmful effects....

Charles II, the last of the Spanish Hapsburgs. Generations of inbreeding left him infertile, in addition to numerous additional health problems. (Credit: Wikimedia Commons) Inbreeding, or mating between two closely-relat...

A new study links changes in the gene for the protein focal adhesion kinase, or FAK, to ovarian cancer's ability to survive chemotherapy.

Scientists have found evidence suggesting that resistance to the 'hunger hormone' ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer's disease (AD). The findings, based ...

With warming temperatures, average snowfall frequency is estimated to decline across the Pacific Northwest by 2100 -- and at a faster rate if greenhouse emissions are not reduced, according to a new study.

(Credit: l i g h t p o e t/Shutterstock) Prominent scientists can be guiding beacons for an entire field. Their work can define research for years to come, and sets a precedent for successive generations. The life of an ...

States that require prescribers to register with and use prescription drug monitoring programs in most clinical circumstances saw notably fewer opioid prescriptions and reduced opioid-related hospital use by Medicaid pat...

A three-year study has shown that there is no benefit in taking high doses of vitamin D. More research is required to determine if high doses may actually compromise bone health.

The study reported 'no significant difference in the effectiveness' of medical masks vs. N95 respirators for prevention of influenza or other viral respiratory illness.

The realities of subsistence living in a region of Senegal hard hit by schistosomiasis make reinfection likely, despite mass drug administration. Researchers find that engaging communities in the design of disease contro...

Using advanced imaging techniques, researchers have mapped a previously uncharted region of the human genome that gives rise to a variety of disease, setting the stage to potentially test for the conditions in the future...

The anti-cancer drug 5-fluorouracil (5FU) acts as a radiosensitizer: it is rapidly taken up into the DNA of cancer cells, making the cells more sensitive to radiotherapy.

In a meta-analysis of 58 studies, a study compared four types of skin cancer treatments and found that while all four had similar recurrence rates a year after treatment, a form of radiation called brachytherapy and a ty...

People who suffered a financial, housing-related, or job-related hardship as a result of the Great Recession were more likely to show increases in symptoms of depression, anxiety, and problematic drug use, research shows...

Implantable defibrillators can save lives, but also harbor risks. A major study has found that a special ECG method can help to identify the patients most likely to benefit from these devices.

Could following a certain type of diet affect the gut microbiome -- the good and bad bacteria that live in the gastrointestinal tract -- in ways that decrease the risk of Alzheimer's disease? According to researchers, th...

Increased p53, the well-known tumor-suppressor protein, can predict whether malaria-infected children will develop fever or other symptoms, suggests a new study. The authors say the findings could lead to new strategies ...

Researchers uncover why some organisms can eat anything -- 'generalists -- and others have strict diets -- 'specialists'. Using different Drosophila species the team found that diversity in diet stems from the flexible r...

Researchers have designed a machine learning algorithm that predicts the outcome of chemical reactions with much higher accuracy than trained chemists and suggests ways to make complex molecules, removing a significant h...
