A surprising new source of attention in the brain

Scientists find a new brain area in control of our attention skills, raising new questions in what has long been considered a settled scientific field.

New clues about why a universal flu vaccine is so elusive

To scientists' surprise, the immune system develops its response to each virus variant mostly from scratch, instead of building on what it has already learned.

Researchers discover a new mechanism in childhood kidney cancer

A problem in reader proteins that identify which gene is up for expression may cause normal cells to turn malignant during development.

Scientists develop new method that predicts vulnerability to stress

Researchers have identified a set of biological factors in mice that seem to determine one's ability to bounce back from a traumatic event, and provide preliminary evidence that a naturally-occurring substance may help boost resiliency in the face of stressful situations.

Neurodegenerative diseases may be caused by molecular transportation failures inside neurons

Protein clumps are routinely found in the brains of patients with neurodegenerative diseases. Now researchers find a link between this buildup and the intracellular movement of proteasomes, molecular machines tasked with degrading protein waste inside cells.

Study sheds new light on how epigenetic events might spur disease

Research that began with the analysis of two developmental syndromes ultimately helped scientists understand how diverse epigenetic mechanisms can combine to drive tissue overgrowth in cancer.

The pathway to Parkinson’s takes a surprising twist

A new study finds that neurons affected in Parkinson’s disease can shut down without fully dying, allowing them to also switch off neighboring cells. The findings might give scientists a better understanding of how the condition wreaks havoc in the brain, as well as ideas for new treatments.

Lymphatic system found to play key role in hair regeneration

To grow new hair, stem cells throughout the skin must work in sync. Researchers have discovered the molecular communication tool, part of the lymphatic system, that the cells use to synchronize their activities.  

Study pinpoints rare genetic change that may boost risk of HPV-related illness

The human papilloma virus is usually kept in check by the immune system, but scientists identified a genetic variant that makes some infected children prone to developing warts in the throat.

Research on cell division provides new clues to how a common cancer treatment works

In studying cell division, scientists happened upon a new way of understanding how a chemotherapy compound works. The findings could make it possible to predict which patients are most likely to benefit from the drug.
