📈 Stock Market Today: The Dollar Strengthens as Investors Watch Rates, Restructuring and Energy Growth

The U.S. dollar has reached an 18-month high, supported by stronger U.S. conditions, elevated Treasury yields and growing uncertainty in Europe.

Meanwhile, investors are tracking major company-specific developments:

🔹 HubSpot plans to eliminate about 660 jobs, or 7% of its workforce.
🔹 Matthews International received a Zacks upgrade to Hold, although broader analyst sentiment remains cautious.
🔹 MPLX continues to show strong gathering-volume growth, but investors are weighing valuation and energy-market risks.
🔹 Federal Reserve rate expectations remain an important influence on yields, currencies and equities.

Could helping other people be linked to a younger-appearing brain? 🧠

A new study in Translational Psychiatry examined 194 adults and found that people who reported providing more social support tended to have lower BrainAGE values—meaning their MRI-estimated brain age was younger relative to their chronological age.

The researchers found the association remained significant after accounting for multiple health, demographic and lifestyle factors. Emotional support showed a particularly notable association in an exploratory analysis.

But there is an important caveat: the study does not prove that helping others slows or reverses brain aging. The research was observational, so the direction and causes of the relationship remain uncertain.

The findings offer an intriguing new avenue for understanding how social relationships and prosocial behavior may relate to healthy brain aging.

🧬 What if your gut bacteria carry clues about where ancient humans traveled?

A new study in Nature has found 1,231 microbial species shared by the Tsimane of Bolivia and the Hadza of Tanzania, two populations separated by thousands of years and thousands of kilometers.

Genetic analysis suggests that some of these microorganisms may have accompanied human populations during ancient migrations.

Even more strikingly, 848 of the shared species were rare or absent in industrialized populations, raising new questions about how modern lifestyles have changed the human microbiome.

Researchers estimate that the microbial populations experienced a median isolation time of about 17,090 years — while emphasizing that the estimate carries uncertainty because microbial genomes can exchange genetic material and contain complex ancestry patterns.

The biggest question now is whether the disappearance of some ancient microbial lineages has consequences for human health. The current study does not provide that answer.
