In the process, Colossal may have handed a useful tool to developmental biology. On Tuesday, biotech startup Colossal announced its newest development on the road to its announced goal: reversing the extinction of species, in this case, avian species. The development itself is essentially an artificial eggshell, one that…
“How in the hell do I get more science into space? That is my goal.” There are more opportunities to access space than ever, thanks to a bevy of commercial rockets, some with reusable boosters, led by SpaceX’s workhorse Falcon 9. So why is NASA launching fewer telescopes and…
Both tools generate hypotheses; one goes on to analyze some of the data. On Tuesday, Nature released two papers describing AI systems intended to help scientists develop and test hypotheses. One, Google’s Co-Scientist, is designed as what they term “scientist in the loop,” meaning researchers are regularly applying their…
For some ancient Aboriginal Australian communities, dingoes were part of the family. A thousand years ago, the ancestors of today’s Barkindji people carefully buried a dingo (or garli, in the Barkindji language) in a mound of shells. Archaeologists recently studied the burial in what’s now New South Wales, Australia.…
New X-rays and CT scans showed small case with locking mechanism containing metal instruments. Archaeologists used a combination of advanced CT scans and 3D digital reconstruction to identify one of the Pompeii victims who died in 79 CE during the eruption of Mount Vesuvius as most likely having been…
Researchers are testing CAR T cell therapy as a way to reset the immune system. At age 49, Jan Janisch-Hanzlik’s multiple sclerosis was destroying her freedom to live the life she wanted. She gave up her active nursing job for a desk role. Frequent falls made her afraid to…
Each year, some of the power solar could have produced is blocked by aerosols. Coal is by far the most polluting fuel that we use. It produces the most carbon emissions per unit of energy, and impurities in the coal produce a lot of sulfur dioxide aerosols, as well…
Instead of running silent and deep, most satellites easily stand out against the blackness of space. The world’s leading space powers desperately want to know what the others are up to high above the equator. For more than a decade, the US military has operated a fleet of “inspector”…
One of the site’s moderators described the new policy on social media. AI-generated slop has shown up everywhere, including in the peer-reviewed literature. Fake citations, unedited prompt responses, and nonsensical diagrams have all slipped past editors and peer reviewers, and it’s not always clear if there are any consequences…
Limestone might not be the only source for Portland cement. Cement production alone currently accounts for about 8 percent of global CO2 emissions, so considerable effort is going into lowering that number. Efficiency can be increased, and energy sources can be swapped for cleaner ones, but a stubborn reality…
