• Scientists identify neurons in mice that, once activated, can change body's metabolic rate, induce hibernation-like state January 21, 2025
  A new study has identified a group of neurons that, when activated, can induce a hypometabolic state, akin to hibernation. The discovery could have far-reaching implications for conditions like obesity, cardiometabolic diseases, and even for space travel. The research team found that these neurons regulate key aspects of the brain-heart-gut axis.
• Reimagining chain mail January 21, 2025
  Experiments have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM (for polycatenated architected materials) could have uses in areas ranging from helmets and other protective gear to biomedical devices and robotics.
• Extreme climate pushed thousands of lakes in West Greenland 'across a tipping point,' study finds January 21, 2025
  Following two months of record heat and precipitation in fall 2022, an estimated 7,500 lakes in West Greenland turned brown, began emitting carbon and decreased in water quality in less than a year. The spike in temperatures caused the precipitation to fall as rain instead of snow. The heat also caused permafrost to thaw, releasing […]
• Astronomers thought they understood fast radio bursts: A recent one calls that into question January 21, 2025
  Fast radio bursts are mysterious and brief flashes of radio emissions that were thought to be produced by magnetars, highly magnetized rotating neutron stars. Yet magnetars appear primarily in young star clusters. A repeating burst discovered last year has been pinpointed to the distant outskirts of an old but massive elliptical galaxy where, theoretically, such […]
• 'Unprecedented' level of control allows person without use of limbs to operate virtual quadcopter January 21, 2025
  A brain-computer interface, surgically placed in a research participant with tetraplegia, paralysis in all four limbs, provided an unprecedented level of control over a virtual quadcopter -- just by thinking about moving his unresponsive fingers.
