The surprising role of RNA in immune interactions

In a groundbreaking exploration of cell surface biology, Ryan Flynn has uncovered a surprising role for RNA outside the confines of the cell. Flynn's research, which focuses on the biology of cell surface RNA, led to the discovery that certain RNAs are chemically linked to glycans - complex carbohydrate polymers found on the cell surface.

The critical role of PGK1 in Parkinson's disease

An enzyme called PGK1 has an unexpectedly critical role in the production of chemical energy in brain cells, according to a preclinical study led by researchers at Weill Cornell Medicine. The investigators found that boosting its activity may help the brain resist the energy deficits that can lead to Parkinson's disease.

Hair follicles use unique sensor system to clean up dead cells

Billions of our cells die every day to make way for the growth of new ones. Most of these goners are cleaned up by phagocytes - mobile immune cells that migrate where needed to engulf problematic substances.

Scientists discover brain's 'future map'

Researchers from the RIKEN Center for Brain Science (CBS) in Japan have discovered a region of the brain that encodes where an animal is planning to be in the near future. Linked to internal maps of spatial locations and past movements, activity in the newly discovered grid cells accurately predicts future locations as an animal travels around its environment. Published in Science on August 15th, 2024, the study helps explain how planned spatial navigation is possible.

Exploring the mechanics of cell migration and growth

The National Institute of General Medical Sciences, a branch of the National Institutes of Health (NIH), has awarded Yubing Sun, associate professor of mechanical and industrial engineering at the University of Massachusetts Amherst, a $1.9 million Maximizing Investigators' Research Award to support the exploration of the fundamental principles behind the process that close gaps caused by injury or growth between cells. This research has the potential to push forward advances in our understanding of wound healing, cellular regeneration therapies and embryonic development.
