Three brain rejuvenation methods may exert their effects through the same molecule, at least partly, which could lead to therapies for cognitive decline.
- Health & Medicine
Mexican virologist Susana López Charretón uncovered rotaviruses’ secrets
Knowledge of the complex dance between virus and host cell has led to the development of life-saving vaccines.
- Health & Medicine
What we still don’t know about Wegovy’s effect on strokes and heart attacks
A clinical trial suggests that semaglutide, a drug used to treat obesity and diabetes, may protect cardiovascular health in a broad group of people.
- Health & Medicine
What to know about the new RSV vaccine for pregnant people
Data on the FDA-approved Pfizer vaccine are promising. Questions about safety and how it might be used in conjunction with another new RSV shot remain.
- Psychology
An apology to Indigenous communities sparks a mental health rethink
The leading U.S. psychological association pledged to embrace Indigenous approaches to healing, which requires rethinking how to address mental health.
- Genetics
The Y chromosome’s genetic puzzle is finally complete
New analyses of the human Y chromosome reveal millions of new bases and different locations for the same gene in different people.
- Archaeology
Pre-Inca people stomped salutes to their thunder god on a special dance floor
Excavation of a drumlike platform in the Andes turned up a structure seemingly designed to absorb shocks and emit resonant sounds when stomped upon.
- Health & Medicine
Health risks can persist at least 2 years after COVID-19, new data suggest
