Scientists Uncover New Mechanism for Degrading Short-Lived 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. These proteins are made in the nucleus and are quickly destroyed once they've done their job.

Innovative Method Accelerates Discovery of New Drugs by Harnessing the Power of Ribosomes

A research team led by University of California, Irvine scientists has developed an innovative method for quickly and efficiently creating vast collections of chemical compounds used in drug discovery by harnessing the power of ribosomes, the molecules found in all cells that synthesize proteins and peptides.

Sensory Neurons Develop Customized Nerve Endings Based on Cues From the Skin, Finds Study

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.

Scientists Develop New Method to Control Insulin Release with Music

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. Researchers led by Martin Fussenegger from the Department of Biosystems Science and Engineering at ETH Zurich in Basel want to make the lives of these people easier and are looking for solutions to produce and administer insulin directly in the body.

Study Finds Diverse Set of Immune Cells Linked to Flu Protection

St. Jude Children's Research Hospital scientists, in collaboration with the Institute of Environmental Science and Research (ESR) Limited, found that immune cells present in people months before influenza (flu) infection could more accurately predict if an individual would develop symptoms than current methods which primarily rely on antibody levels.
