Researchers found that TIMP2 supports microglial function and reduces age-related cellular changes associated with inflammation in mice. As the brain grows older, its immune cells can become less effective at clearing debris and controlling potentially harmful responses. Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for TIMP2, a protein [...]

A large study of older adults in China suggests that depression can lead to a decline in memory and thinking skills by causing people to withdraw from their social circles, highlighting a potential pathway to protect aging brains.

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.

When you recognize a familiar face, your brain must connect that face with a name,...

Understanding how molecular changes shape brain function and disease requires more than measuring genes in bulk tissue.

Findings from a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons suggest that the trickle of neurons created in the adult hippocampus could be instrumental in preventing depression. Most of the brain’s 100 billion neurons are created before birth. Published in the journal Nature Medicine, the study shows for the […]

Nature Communications, Published online: 22 August 2026; doi:10.1038/s41467-026-76998-z Sex hormones and cancer-cell sex influence tumor growth, but other sex-dependent drivers of oncogenesis remain unclear. Here, the authors reveal that the sex of central neurons alters the peripheral tumor-supportive niche to promote tumor growth.
