In mice, restoring a thymus hormone calmed inflamed immune cells and improved cancer treatment in old age.

A hormone from the thymus gland called thymulin drops as people and mice get older. This drop lets certain immune cells become more inflamed. Inflamed immune cells help tumors grow and resist treatment. In mice, giving back thymulin calmed these cells, boosted tumor fighting cells, and made cancer immune therapy work better in older animals.

What it could change A thymus hormone that drops with age was shown to calm inflamed immune cells in old mice.

This describes a lab finding in aged mice, not a treatment tested in people.

Mice and lab cells only, no human trial yet.

In monkeys, opening the brain's shield on one side made the opposite side work harder for oxygen.

Doctors want to use focused sound waves to briefly open the brain's protective shield. This lets drugs pass through into the brain. In monkeys, opening this shield on one side of the brain left the treated spot unchanged. But the matching spot on the other, untouched side had to work much harder to get oxygen. This shows the treatment can affect brain areas far from where it was aimed.

What it could change Opening the brain's shield on one side stressed the matching spot on the other side.

Shown only in monkeys using brain oxygen scans, not tested in human patients.

Monkey study only, small sample, effects on humans still unknown.

In a model, healthier diets by 2050 would cut global farm value by 1.6 trillion dollars.

A model looked at what would happen if the world shifted to healthier diets, cut food waste in half, and farmed more efficiently by 2050. Global farmland would shrink by 6%. Farm production would fall 17% below current plans, and total farm value would drop by 1.6 trillion dollars. Meat farming would shrink a lot, while fruits, vegetables, nuts, and beans would grow instead.

The number 1.6 trillion dollars

The projected drop in global farm production value by 2050 if diets became healthier and food waste was cut.

Model based projection only, not an observed real world change yet.

A DNA study found 11 gene locations linked to borderline personality disorder.

A large study of DNA looked at over 12,000 people with borderline personality disorder and more than a million people without it. Scientists found 11 spots in DNA linked to the disorder. They also found 9 genes that may raise risk. The genetic risk overlaps with depression, PTSD, ADHD, and physical illnesses like diabetes and lung disease.

The number 11 gene locations

The number of DNA spots linked to borderline personality disorder in this genetic study.

One ancestry group studied, genetic score explains only 4.6% of risk.

Body size, diet, and brain size predict extinction risk in large tropical mammals across scales.

Some traits reliably predict which large tropical forest mammals are at risk of dying out, no matter if you study the whole world or just one region. This held true for body size, how long each generation lives, diet, brain size, and whether the animal climbs trees. But when studies also looked at different time spans, the risk predictions changed. This means big global studies can help guide local conservation, but only if scientists account for how much history each study covers.

The number 210 species

The number of tropical forest mammal species analyzed across 64 forests and three biogeographical regions.

Historical and regional data only, no live population testing.
