The race to build data centers in space is gaining momentum as AI drives unprecedented demand for computing power。 Orbital facilities could tap into abundant solar energy and avoid many of the environmental challenges faced on Earth。 Yet space remains a harsh and expensive place to operate, with major hurdles including cooling, maintenance, radiati
Quick framing, since the post is long: I did robotic manipulation research at OpenAI from 2017–2020, and the tabletop setup back then cost roughly 10x this one and took a team to run。 This project is me testing whether a single person can now do meaningful work on the same class of problems: starting with physical and software setup。A few decisions
Researchers used genome editing to block the production of red pigments in lettuce, causing other beneficial plant compounds to build up instead。 The lettuce continued to grow normally, pointing toward a new way to create crops with customized nutritional profiles
As tech giants rush to build infrastructure, some residents who live near data centers say a constant low-frequency vibration is ruining their health and homes
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
Hey HN - we’re Oskar, Szymon, and Piotr, and we’re building TesterArmy (https://tester。 TesterArmy is an agentic testing platform that runs end-to-end checks before deployment and in production。 Instead of wasting hours on manual testing or maintaining static scripts, we let you specify your tests in natural language and handle everything in betwee
Scientists have found that staple-shaped particles can tangle together to create a material that is both strong and flexible。 Unlike conventional materials, these particles can be locked into a sturdy structure or rapidly unraveled using vibrations。 The unusual behavior could open the door to recyclable buildings, reconfigurable structures, and eve
Researchers propose that tiny mineral nanoparticles may have been the hidden engines that transformed Earth’s early chemistry into the first building blocks of life。 By acting as natural catalysts and energy processors, these “nanozymes” could help explain how lifeless matter gradually became living systems
Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off。 Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring
