Researchers discover how proteins regulate 'treadmilling' in cells

Researchers at the Centre for Genomic Regulation (CRG) have discovered how proteins work in tandem to regulate 'treadmilling', a mechanism used by the network of microtubules inside cells to ensure proper cell division.

Midnolin protein plays key role in breaking down short-lived nuclear proteins

Short-lived proteins control gene expression in cells to carry out a number of vital tasks, from helping the brain form connections to helping the body mount an immune defense.

Lung cells can be trained to counteract inflammation

Inflammation is a standard part of our bodies' immune system response. But sometimes this response becomes hyperactivated in our lungs, causing inflammation to continue unchecked, which can be fatal. Many deaths from COVID-19 have been due to excessive inflammation, which results in acute lung injury.

Skin signals neurons to grow the appropriate endings

Nerve cells that sense touch grow the appropriate endings for hairy or hairless skin based on cues from the skin itself, rather than through predetermined programming, according to research led by Harvard Medical School scientists and published Aug. 21 in Developmental Cell.

Music can trigger cells to release insulin within minutes

Diabetes is a condition in which the body produces too little or no insulin. Diabetics thus depend on an external supply of this hormone via injection or pump.

Time-restricted feeding may correct the circadian disruptions in Alzheimer's disease

One of the hallmarks of Alzheimer's disease is disruption to the body's circadian rhythm, the internal biological clock that regulates many of our physiological processes.

Global team of experts outlines roadmap for human skin cell atlas

As a single organ, our skin is able to perform a broad repertoire of vital functions. Dermatology experts call for a reference guide to single-cell composition of normal human skin, which is still lacking.

Astronauts' bone marrow fat can help replenish red blood cells and bone after space travel

A study of 14 astronauts suggests that while space travel depletes red blood cells and bone, the body can eventually replenish them back on Earth with the help of fat stored in the bone marrow.
