Astronauts lose decades of bone mass in space that many don’t regain even after a year back on Earth, researchers said Thursday, warning that it could be a “big concern” for future missions to Mars. Previous research has shown that astronauts lose between 1 and 2 percent of their bone density for each month spent … Read more
An artist’s reconstruction of Ailurarctos of Shuitangba. The grasping function of its false thumb (shown in the individual on the right) has reached the level of modern pandas, while the radial sesamoid may have protruded slightly more than its modern counterpart during walking (seen in the individual on the left ).

The massive eruption of the submarine volcano Tonga in the Pacific earlier this year generated an explosion so powerful it sent massive pressure waves through the atmosphere and around the globe. These waves were the fastest ever seen in our atmosphere, reaching speeds of 720 miles (1,158 kilometers) per hour, according to a new study. … Read more
A team of MIT researchers is studying a radical method to counter the effects of climate change, a press release reveals. They propose using a fleet of “space bubbles” to reflect sunlight away from Earth. As we all know, such crazy ideas wouldn’t even be on the table if humans had drastically reduced their use … Read more

Credit: NOAA and National Environmental Satellite, Data, and Information Service (NESDIS) The eruption of the Hunga Tonga-Hunga Ha’apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed. … Read more
The beloved dog that snores on your couch or sticks its nose under your arm at dinnertime comes from a much wilder origin. At some point dogs diverged from gray wolves under the guidance of domestication, becoming the various fuzzbutts that fill our homes and hearts with such joy today. However, when and how this … Read more
A new spacecraft selfie shows the machine in glorious 4K resolution above Australia’s Great Barrier Reef. NanoAvionics, a satellite company based in the United States and the United Kingdom, has released a high definition video (opens in a new tab) from space Wednesday June 28 showing their MP42 microsatellite (opens in a new tab) flying … Read more
From July 3, 2022, CERN celebrates the tenth anniversary of the discovery of the Higgs boson, with collisions at “unprecedented energy levels” predicted for the 5th – note: good CERN scientists don’t expect not to “open a portal”, as some have suggested. TikTokers of particular persuasion took the opportunity to warn their listeners about “timeline … Read more
The new research has found that human bones, like the wrist the bone shown here, suffers from an accelerated loss of density as a result of long-long-term assignments space. Image: L. Gabel et al., 2022 Long term exposure to microgravity results in loss of bone density, and new research reveals just how often this happens … Read more
Radio images obtained from the reanalysis, showing the center of the elliptical galaxy M87. The upper left panel shows a close-up around the black hole, depicting the “core” (the round red spot in the lower center) and the “nodes” (elongated spots in the center right and lower right). The widefield image shows the jet extending … Read more
