Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without destroying beneficial species.
A study comparing 100 primate species, including humans, suggests that everyday aggression and lethal violence did not evolve as part of the same simple behavioral spectrum. Species that frequently fight or show mild aggression are not necessarily more likely to kill rivals, while extreme acts such ...
Predatory wasps are hijacking shelters built by tropical trees for their ant defenders, potentially disrupting an ancient partnership that protects the plants from hungry insects. The takeover is far more common in disturbed landscapes such as oil palm plantations and could have lasting consequences...
Ancient pottery from Tampa Bay appears to have been made by migrant craftspeople who brought specialized Mississippian pottery-making knowledge hundreds of miles south. Remarkably, they even incorporated crushed fragments of older homeland pottery into new vessels, preserving a physical link to thei...
Researchers have captured key steps in a chemical reaction that helps nature transfer energy with remarkable efficiency. Ultrafast X-rays revealed how changes involving electrons and protons are closely linked to the rearrangement of surrounding water molecules. Because similar reactions drive photo...
Couples who exercise together report better communication, healthier conflict resolution, and lower marital stress than those who work out alone. Even something as simple as taking a walk together may create valuable opportunities to talk, listen, and feel more connected.
Physicists at CERN’s Large Hadron Collider have captured the clearest evidence yet that quark-gluon plasma, the scorching-hot matter that filled the newborn universe, behaves like a true liquid. By tracking individual quarks as they blasted through the plasma, researchers saw them leave behind rippl...
Scientists have found a surprising way to regrow damaged knee cartilage by blocking a protein that becomes more abundant with age. In old mice, the treatment restored naturally lost cartilage and also helped prevent osteoarthritis after ACL-like knee injuries, while human cartilage taken from knee r...
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 whi...
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 mo...
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 pre...
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 coul...
