'Bad' cholesterol not as bad as people think, shows Texas A&M study

A Texas A&M University study challenges the common perception of LDL cholesterol as 'bad' cholesterol. Research suggests that a certain amount of LDL is necessary for muscle growth and serves as a warning sign for potential health problems. The study's findings may have implications for conditions like sarcopenia, which affects million...

Study gives clues to how obesity spreads socially

A study by Arizona State University researchers found that shared ideas about acceptable weight or body size play a minor role in spreading obesity among friends. The team discovered that interventions targeting behaviors, such as changing eating habits, are more effective than those focused on body mass indexes or body sizes.

Wistar researchers: Direct proof of how T cells stay in 'standby' mode

Researchers at The Wistar Institute have found that the protein Foxp1 actively maintains T cells in a 'quiescent state,' allowing them to work without antigenic triggers. Removing Foxp1 enables T cells to proliferate and become activated, which could lead to new treatments for diseases like cancer.
