Boosting a single molecule in the brain can change 'dispositional anxiety,' the tendency to perceive many situations as threatening, in nonhuman primates, researchers have found. The molecule, neurotrophin-3, stimulates ...

For children and teens with migraine, the pain and symptoms that accompany migraine attacks can be debilitating, resulting in missed school days, absence from social or sporting events, and affected home activities. Now ...

A study has found that combining acyclovir -- a commonly prescribed topical herpes medication -- with particles of activated carbon improves efficacy of the drug.

Bacteria, like people, have complicated relationships. A group of researchers was able to engineer the genomes of 4 species of gut bacteria to make them rely on each other for essential nutrients rather than competing fo...

Medicinal chemists are exploring a small molecule drug known as DYR219. The promising therapy, while still in the experimental stages, may succeed where other treatments have failed, and could be effective against a rang...

Scientists have identified a pair of genes that influence risk for both late-onset and early-onset Alzheimer's disease.

Metastasis, in which cancer cells break free from the primary tumor and form tumors at other sites, worsens the prognosis for many cancer patients. The lymph nodes -- glands of the immune system located throughout the bo...

Researchers have developed a new approach to understand intricate changes that control how proteins function in our cells in health and disease. The new proteomics technique called 'ubiquitin clipping' allows researchers...

Staphylococcus aureus bacteria are a major cause of serious infections that often persist despite antibiotic treatment, but scientists have now discovered a way to make these bacteria much more susceptible to some common...

Gluten-free diets have been trendy for several years now, with adherents claiming that avoiding grains that contain the substance helps with weight loss or improves general health. However, for people with celiac disease...

A team of researchers has designed a study to see whether older adults who are physically active before having surgery had less delirium after surgery. The research team had previously found that people who enjoy activit...

A phase 1 clinical trial testing a new drug in pancreatic cancer had promising initial results, report researchers. The trial looked at AZD1775, an inhibitor designed to block an enzyme called Wee1, which plays a role in...

Facing the threat of domestic violence, being a survivor of sexual assault, struggling with depression or thoughts of suicide are four topics that are difficult to broach with anyone. Including those who can help you. A ...

A team has shown how, in osteoarthritis patients, the viscous lubricant that ordinarily allows our joints to move smoothly triggers a pain response from nerve cells similar that caused by chilli peppers.

Researchers have refined the famous CRISPR-Cas method. Now, for the very first time, it is possible to modify dozens, if not hundreds, of genes in a cell simultaneously.

Patients with metastatic colorectal cancer who engaged in moderate exercise while undergoing chemotherapy tended to have delayed progression of their disease and fewer severe side effects from treatment, according to a n...

Medical scientists have developed an advanced method for perfectly detecting low-level somatic mutation in patients with intractable epilepsy. Their study showed that deep sequencing replicates of major focal epilepsy ge...

A new study has found that genes have a greater influence than previously thought not only on the number of moles you have but also where they are on your body.

An extensive study has confirmed that the risk of developing celiac disease is connected to the amount of gluten children consume. The new study is observational and therefore does not prove causation; however, it is the...

A comprehensive dementia care program staffed by nurse practitioners working within a health system improves the mental and emotional health of patients and their caregivers.
