Scientists discovered a small protein region that determines whether plants reject or welcome nitrogen-fixing bacteria. By tweaking only two amino acids, they converted a defensive receptor into one that supports symbiosis. Early success in barley .. ...

Researchers uncovered rare azurite traces on a Final Paleolithic artifact, overturning assumptions that early Europeans used only red and black pigments. The find suggests ancient people possessed deeper knowledge of minerals and colors than believed ...

Ancient pterosaurs may have taken to the skies far earlier and more explosively than birds, evolving flight at their very origin despite having relatively small brains. Using advanced CT imaging, scientists reconstructed the brain cavities of ...

Scientists have confirmed that Nanotyrannus was a mature species, not a young T. rex. A microscopic look at its hyoid bone provided the key evidence, matching growth signals seen in known T. rex specimens. This discovery suggests a richer, more ...

Researchers revealed that the microbial metabolite TMA can directly block the immune protein IRAK4, reducing inflammation and improving insulin sensitivity. The molecule counteracts damage caused by high-fat diets and even protects mice from sepsis. ...

Scientists found that kale's prized nutrients are hard for the body to absorb unless they're eaten with oil. Cooking doesn't improve absorption, but adding oil-based dressings--or even more advanced nanoemulsion sauces--does. These combinations ...

High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact within these droplet-like structures. The findings connect molecular architecture to the broader behaviors of these droplets . ...

A newly analyzed set of climate data points to a major volcanic eruption that may have played a key role in the Black Death's arrival. Cooling and crop failures across Europe pushed Italian states to bring in grain from the Black Sea. Those shipments ...

A century-old North Atlantic cold patch is now linked to a long-term slowdown in the AMOC, the climate-regulating conveyor belt of ocean water. Only weakened-AMOC models match observed temperature and salinity patterns, overturning recent model ...

A new radiocarbon study has clarified the timing of the colossal Thera eruption, placing it before Egypt's New Kingdom. Researchers analyzed artifacts tied to Pharaoh Ahmose, gaining rare access to museum materials. Their results favor a younger ...
