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 ...

Giving children an additional dose of rotavirus vaccine when they are nine months old would provide only a modest improvement in the vaccine's effectiveness in low-income countries, according to a new study.

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.

The field of topology or the study of how surfaces behave in different dimensions has profoundly influenced the current understanding of matter. The prime example is the topological insulator, which conducts electricity ...

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...

Scientists have analyzed the genetic repertoire of bacteria in the human mouth and gut. The effort marks the first chapter in efforts to compile a compendium of all genes in the human microbiome. Mapping the microbial ge...

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 breakthrough in understanding how the quasi-particles known as magnetic monopoles behave could lead to the development of new technologies to replace electric charges.

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.
