How Brain Tumors Make “Traitors” of Some Immune Cells

A new study has exposed how the tumor microenvironment of brain cancers alters the biology of immune cells to promote malignant growth.

New Insights Into Stress Granule Formation

Researchers at Weill Cornell Medicine have illuminated one of the important ways that cells respond to stress. The findings could also be relevant to Alzheimer’s, ALS and other diseases in which this mechanism may be abnormally active.

Gene Variant That Increases Parkinson’s Disease Risk Found in People of African Ancestry

A variant – found almost exclusively in people of African ancestry – of the gene that encodes β-glucocerebrosidase increases the risk of developing Parkinson’s disease, reports a new study.

Clear Picture Demonstrating How the Human Brain Organises Language

A new study has provided the first clear picture of where language processes are located in the brain. The findings may be useful in clinical trials involving language recovery after brain injury.

Stopping Cancer Tumors “Hijacking” the Genetic Program Used by Developing Nerves

Cancer tumors "hijack" the genetic program used by developing nerves. In the long term, the results may open up new ways of treating cancer by limiting the tumour’s interaction with the nerves.

Climbing More Than Five Flights of Stairs a Day Reduces Heart Disease Risk

Forget walking 10,000 steps a day. Taking at least 50 steps up the stairs each day could significantly slash your risk of heart disease, according to a new study.

Saturated Fat May Disrupt Memory Creation in the Aging Brain

New research hints at a few ways fatty foods affect cells in the brain, a finding that could help explain the link between a high-fat diet and impaired memory – especially as we age.

Are Our Brain Cells More Vulnerable to Parkinson's at Night?

Disturbances in sleep patterns and the internal biological clock are frequently associated with Parkinson’s disease. However, the link between biological rhythm and neuronal degeneration remains unclear.

Patients Still Prefer Daily Oral PrEP Even With the Development of New Options

When PrEP (pre-exposure prophylaxis), a drug that prevents HIV infection, was first approved by the FDA in 2012, it was a medical breakthrough. A new study explores patient preference for the standard method and new options.

How an Audience Changes a Songbird’s Brain

As a zebra finch becomes single-minded about impressing a possible mate, dopamine-releasing brain cells reflect his intentions, helping to explain what our brains are doing as our priorities change.
