Stopping Ozempic may raise heart attack and stroke risk
A large study suggests the cardiovascular benefits of GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound can disappear surprisingly quickly when treatment stops. After two years off the medications, patients had a 22% higher risk of heart atta…
Black holes of every size follow the same surprising rule
Scientists have found evidence that black holes of vastly different sizes may launch powerful jets according to the same universal rule. Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands…
A new process turns plastic waste into gasoline and diesel fuel
Scientists at Oak Ridge National Laboratory have developed a surprisingly simple way to turn polyethylene, the common plastic used in shopping bags and cutting boards, into gasoline and diesel-like fuels. The process uses inexpensive aluminum-based mol…
Scientists create a needle-thin brain implant that can do three jobs at once
A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give scientists a more precise, less invasive way to study the brai…
NASA just powered up Roman’s massive 300-megapixel camera
NASA’s Roman Space Telescope has successfully activated its 300-megapixel infrared camera, which will capture enormous stretches of the cosmos with Hubble-like sharpness. Its planet-hunting coronagraph is also working as expected, putting Roman another…
Amazon study reveals the best strategies for protecting biodiversity and carbon
A large Amazon study suggests the most powerful conservation move may be protecting the forests that are already standing. Preventing damage from wildfires and logging delivered the greatest biodiversity benefits and nearly matched deforestation preven…
Chronic stress may be quietly reshaping your heart
Chronic inflammation tied to stress, lifestyle, mental health, and socioeconomic conditions may silently change the heart for years before any symptoms appear. People with the highest inflammation levels faced a 43% greater risk of heart attack and str…
Stanford scientists discover the human brain may actually be two separate organs
Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also allowed researchers to grow human hindbrain neuron…
What kills Schrödinger’s cat? Gravity may not be the answer
Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to one of its toughest experimental tests yet. Deep beneath Italy’s Gran Sasso mountain, researchers searched for an extremely faint…
