Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The increase appears to come from growing muscle and lean tissue as children prepare for later growth. Researchers say this normal process has been mistakenly treated as an obesity warning sign for 42 years.

While toilet seats can carry bacteria, viruses, and even parasite traces, studies show they’re often cleaner than high-touch surfaces like door handles and flush levers. The biggest hidden threat comes from “toilet plumes”—tiny germ-filled droplets launched into the air when flushing without a lid—and from poor hand hygiene.

Men are more likely to develop harmful abdominal fat and signs of liver stress, while women show higher inflammation and cholesterol levels. These differences could help explain why health risks vary between sexes. Scientists say this could lead to more tailored treatments for obesity.

This approach uncovered hidden interactions in viruses like HIV and Ebola that traditional methods missed. By recreating the virus’s membrane environment, researchers can better understand how immune defenses work. The technique could speed up the development of more effective vaccines.

New research reveals that everyday plant compounds—like menthol from mint, cineole from eucalyptus, and capsaicin from chili peppers—can team up inside immune cells to dramatically boost their anti-inflammatory power. While individual compounds showed modest effects, certain combinations amplified results hundreds of times over by activating different cellular pathways at once.

Researchers found that certain lung cells can trigger an exaggerated immune response, creating clusters of inflammatory cells that end up damaging lung tissue instead of protecting it. In experiments, activating this aging-related signal in young mice caused their lungs to behave like older ones, leading to severe illness.

In people already at high risk, it cut major cardiac events by 46% and deaths by an impressive 66% within a year. Scientists think preventing shingles may also stop clot-related complications that can lead to heart attacks and strokes. The effect is so strong, it rivals the benefits of quitting smoking.

Key mutations—like those linked to breast cancer—appear in both species, and some human cancer drugs may also work in cats. Because pets share our environments, these similarities could reveal shared causes of cancer. The research could lead to new treatments that benefit both animals and humans.

After a severe flu-triggered infection destroyed his lungs and caused multiple organ failure, doctors removed both lungs entirely to stop the spread of infection. In their place, they used a specially engineered “artificial lung” system to oxygenate his blood and keep his body functioning while he stabilized.

Scientists are now testing a new platform called DoriVac, which uses folded DNA nanostructures to better control how the immune system responds. In early studies, it produced strong antibody and T cell responses in both mice and human models. Researchers say it could lead to more stable, easier-to-manufacture vaccines for diseases like COVID-19, HIV, and Ebola.

Researchers engineered a more powerful CD40 agonist antibody and changed how it’s delivered—injecting it directly into tumors instead of into the bloodstream. In a small clinical trial of 12 patients with metastatic cancers, six saw their tumors shrink and two experienced complete remission.
