Cancer-fighting t cells burn out. Scientists may have found a fix

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn through their energy while producing cancer-killing proteins. In animal and laboratory studies, blocking MEK helped the cells conserve energy, survive longer, and remain active even in the harsh environment around tumors.

Scientists discover a human brain gene that can jump through DNA

Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a transposon, but unlike most genes that arose this way, it never lost its mobility. Researchers even found BC200 embedded inside a human poxvirus, suggesting it may have jumped from infected skin cells into the virus.

A new kind of magnetism could unlock faster, more efficient computers

Scientists have discovered evidence of altermagnetism in a thin, highly tunable material that could help electronics use electron spin instead of relying only on electrical charge. The unusual magnetic state may enable faster, more energy-efficient devices without the unwanted magnetic interference caused by conventional magnets.

This mysterious hole on the Moon may open into a giant cave

NASA has selected the GIMLI project to investigate whether the Marius Hill Pit opens into a vast underground cave or lava tube. Using radar, seismic sensors, gravity measurements, and cameras, researchers will search beneath the lunar surface and estimate the size of any hidden void. Such caves could preserve clues to the Moon’s volcanic history and potentially provide protected shelters for future astronauts.

Vagus Nerve Stimulation Could Help New Skills Stick

Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect was linked to rhythmic changes in brain blood vessels, hinting that body-to-brain signals may help prepare the brain for lasting change.

The “glue” holding your cells together has a surprising second job

Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers found that cells can dramatically reshape their lower surfaces to engulf cellular debris while keeping their upper surfaces stable, allowing protective barriers to remain sealed.

Easing constipation: A 20-minute walk can get your gut moving almost immediately

Researchers found that just 20 minutes of comfortable walking can rapidly stimulate the gut. Within one to two minutes after exercise, bowel sounds became stronger, more frequent, and lasted longer, suggesting increased intestinal movement. The boost was brief, fading within a few minutes, but it may help explain why walking can provide relief from constipation.
