Five people with lupus went into complete remission after immunotherapy
Ed Cara | Gizmodo
“In their new research, published Thursday in Nature Medicine, Schett and his team infused five patients with treatment-resistant SLE with engineered anti-CD19 T cells. And so far, all have had a remarkable recovery. Their symptoms all improved, with none showing signs of lupus-related internal damage up to 17 months later and minimal side effects from therapy.

AI that can design new proteins could unlock new remedies and materials
Melissa Heikkila | MIT Technology Review
“Traditionally, researchers design proteins by modifying those that occur in nature, but ProteinMPNN will open up a whole new universe of possible proteins that researchers can design from scratch. “In nature, proteins basically solve all of life’s problems, from harvesting solar energy to making molecules. In biology, everything happens from proteins,” says David Baker, one of the scientists behind the paper and director of the Institute for Protein Design at the University of Washington.archive page

Construction technology that inflates the structure could give 3D printing a run for its money
Ben Coxworth | New Atlas
“We’ve heard that 3D-printed concrete buildings can be built quickly and easily, but could there be an even faster and easier method? According to American inventor Alex Bell, there definitely are – and it involves inflating buildings and then pumping concrete into them. …’For our 100 square feet [9.3 sq m] and 200 square feet [18.6 sq m] prototypes, inflation took 7-10 minutes with air,” he said. “Then the concrete pump filled them in 1.5 hours. Including labor, our prototypes cost only $20 per square foot. It’s significantly cheaper than anything else.

2 Minutes to Midlife: The Unspecified Fantastic Future of Epigenetic Clocks
Robin Donovan | NEO.VIE
“When Horvath first described epigenetic clocks, scientists began to speculate that altering them could reverse aging. After all, if certain DNA methylation patterns at certain sites in the cells of certain tissues in your body are hallmarks of aging, could shifting them somehow reverse aging? The short answer: it is possible.”

Roblox avatars are about to get more expressive
Tanya Basu | MIT Technology Review
“Roblox users will soon be able to give their avatars facial expressions that mimic those of the player, the platform announced today. … And soon, according to Roblox, users will be able to speak directly with other avatars as in other In short, the changes could blend our real-world human experience with that of the metaverse and make avatars more like ourselves, for better or worse.


How long is the journey to the edge of the universe?
Randall Munroe | The New York Times
“The limit of the observable the universe is about 270,000,000,000,000,000,000,000 miles away. If you drive at a constant speed of 105 km/h, it will take you 480,000,000,000,000,000, or 4.8 × 10¹⁷, to get there, or 35 million times the current age of the universe. …Be sure to pack extra snacks.

“The [robot] The jumper had reached a record height of about 32.9 meters, as Keeley and his collaborators, led by Elliot Hawkes, a mechanical engineering researcher at the University of California, Santa Barbara, reported in April in Nature. Not only had it jumped more than three times higher than other experimental robots built for the task, but it had jumped more than 14 times higher than any other creature in the animal kingdom. In all likelihood, their robot jumped higher than anything that had ever been done on Earth.

Saturn’s rings finally explained after more than 400 years
Ethan Siegel | think big
“Observed since the invention of the telescope in 1609, Saturn’s rings were a completely unique feature in our solar system. While the other giant planets have since been discovered to have rings, they are faint and unimpressive by comparison. to those of Saturn. Despite all that we have learned about our solar system, the origin of Saturn’s rings has remained an unsolved enigma. Perhaps, that is, until now.
