Study reveals how smell receptors work

Olfactory receptors respond to a variety of odors by binding to large numbers of different molecules, rather than specific chemical features. The team discovered that the amino acids lining the pocket don't form strong chemical bonds with odorants, but instead recognize their general chemical nature.

Researchers link neurodegenerative disease protein to defective cholesterol metabolism

A recent study discovered that brain cells cannot maintain the myelin sheath in the absence of the TDP-43 protein. Restoring cholesterol levels has been proposed as a potential therapeutic strategy for neurodegenerative diseases associated with TDP-43. The research found that oligodendrocytes, responsible for producing myelin, have def...

Study links economic mobility to racial mortality gaps

A recent study by the American Cancer Society found a strong association between economic mobility and racial disparities in mortality in the US. The study suggests that structural racism has persisted with similar magnitude across generations, leading to increased death rates among Black individuals compared to their White counterparts.
