Researchers have developed a new oral drug that boosts metabolic activity in muscle rather than altering appetite like GLP-1 drugs. Early trials suggest it improves blood sugar control and fat metabolism while preserving muscle mass, with fewer side effects. Because it acts through a different mechanism, it could be paired with GLP-1 treatments for even stronger results.

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 trends. This slowdown affects weather systems, jet streams, and marine life throughout the Northern Hemisphere. The discovery sharpens climate forecasts and highlights a major shift already underway.

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 chronology for early 18th Dynasty Egypt. The revised timeline reshapes regional historical connections.

Researchers have found scientific support for the viral claim that rosemary can improve wound healing. Carnosic acid, a natural antioxidant in rosemary, promoted scar-free healing in mice by activating a nerve sensor tied to regenerative repair. Rosemary proved more potent and gentler than other herbs or compounds that target the same pathway. The work hints at a low-cost future option for reducing scarring in humans.

Knotted structures once imagined by Lord Kelvin may actually have shaped the universe’s earliest moments, according to new research showing how two powerful symmetries could have created stable “cosmic knots” after the Big Bang. These exotic objects may have briefly dominated the young cosmos, unraveled through quantum tunneling, and produced heavy right-handed neutrinos whose decays tipped the balance toward matter over antimatter.
