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…
The vacuum giveth, the vacuum taketh, but the vacuum doesn’t let you taketh. This week, a company called Casimir Inc. emerged from “stealth mode” to announce that it had raised significant funding from venture capitalists willing to roll the dice on free energy. That’s right: a startup has gotten…
SpaceX’s upgraded Starship is set to launch on its first test flight as soon as Tuesday, May 19. Welcome to Edition 8.41 of the Rocket Report! The stories of the world’s two most powerful rockets are now intertwined. Hardware for NASA’s third Space Launch System rocket is coming together…
Study suggests “the bias is real but socially constructed, rather than grounded in how women actually sound.” Vocal fry, aka “creaky voice,” is a distinctive drop in pitch, usually at the end of sentences, associated with the speech patterns of young women in particular. Britney Spears is the go-to…
Ocean heat plus human-caused global warming is a grim recipe for deadly climate extremes. Scientists said this week that a developing El Niño is likely to amplify heatwaves, droughts and floods this year, but warned that the long-term warming caused by burning fossil fuels remains the main driver of…
Distinct form of tooth protein in Homo erectus shows up in Denisovans—and us. Humanity’s ancestry has grown far clearer thanks to our ability to obtain ancient DNA. We now know that, as humans left Africa, they interbred with the groups they met there, Neanderthals and Denisovans. Evidence from the…
