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 ...

Researchers successfully implanted a genetically modified pig liver into a human, proving that such an organ can function for an extended period. The graft supported essential liver processes before complications required its removal. Although the .. ...

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features emerged in ancient anoxic oceans long before oxygen ...

Researchers have uncovered a new species of wolf snake on Great Nicobar Island and named it Lycodon irwini in tribute to Steve Irwin. The glossy black, non-venomous snake grows up to a meter and appears confined to a small area. Scientists warn its . ...

An immense Bronze Age settlement has emerged from the Kazakh Steppe, revealing a surprisingly urban and industrial society where archaeologists once expected nomadic camps. At Semiyarka, researchers uncovered massive residential compounds, a possible ...
