Study helps explain why motivation to learn declines with age

Neuroscientists have identified a brain circuit critical for learning to make decisions that require evaluating the cost or reward of an action. They showed this circuit is negatively affected by aging and in Huntington's disease.

How exercise stalls cancer growth through the immune system

People with cancer who exercise generally have a better prognosis than inactive patients. Now, researchers have found a likely explanation of why exercise helps slow down cancer growth in mice: Physical activity changes the metabolism of the immune system's cytotoxic T cells and thereby improves their ability to attack cancer cells

Gut hormone blocks brain cell formation and is linked to Parkinson's dementia

A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson's Disease.

Mouthwashes, oral rinses may inactivate human coronaviruses, study finds

Certain oral antiseptics and mouthwashes may have the ability to inactivate human coronaviruses, according to a new study. The results indicate that some of these products might be useful for reducing the viral load, or amount of virus, in the mouth after infection and may help to reduce the spread of SARS-CoV-2, the coronavirus that causes COVID-19

Scientists develop new precision medicine approach for pancreatic cancer

News report Scientists from the University of Glasgow are developing new ways to predict who will respond to drugs targeting damaged DNA in pancreatic cancer. Publishing their findings in Gastroenterology , the team used cells grown in the lab (cell lines) and mini replicas of patients’ tumours (organoids) to identify molecular markers that can predict which tumours will respond...
