Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own preserved youthful microbiome showed less inflammation, reduced DNA damage, and no signs of liver cancer. Researchers also found that the treatment suppressed a cancer-linked gene called MDM2, making older mice biologically resemble younger ones.

A colossal underwater volcano in the South Pacific may have revealed a surprising new weapon against climate change. After the 2022 eruption of Hunga Tonga–Hunga Ha’apai, scientists detected enormous amounts of formaldehyde in the atmosphere — a telltale sign that methane, one of the planet’s most powerful greenhouse gases, was being destroyed. Researchers now believe volcanic ash mixed with salty seawater and sunlight created reactive chlorine particles that effectively “cleaned up” some of the methane released by the eruption itself.

Scientists have uncovered strong evidence that a major Atlantic Ocean current system tied to global climate is weakening. The slowdown has been detected across a vast region of the North Atlantic over nearly two decades. Since this ocean circulation helps regulate weather and temperatures, changes could affect storms, rainfall, sea levels, and even winter conditions in parts of Europe and North America.

Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up melting from below. Even regions of East Antarctica once considered relatively stable may be far more vulnerable than scientists realized. Researchers warn that current climate models may be missing this dangerous process entirely, meaning future sea level rise could be underestimated.

Scientists may have found a smarter, safer way to wipe out termites hiding inside homes. A chemical called bistrifluron prevents drywood termites from forming new exoskeletons during molting, killing entire colonies from within. In tests, it eliminated about 95% of termites while avoiding the toxic side effects of traditional fumigation. Researchers say the method could provide longer-lasting protection as termites spread into new areas.
