๐งซ Bacteria swim using a tiny electric motor that spins several hundred times per second
Researchers have now mapped every part of the flagellar motor that bacteria use to swim, after more than 50 years of research. The motor spins several hundred revolutions per second and is powered by protons streaming into the cell at more than 2,000 per second.
๐ฆพ Startups that learned to use AI correctly generated 1.9 times higher revenue
Startups that learned how other companies had reorganized their operations around AI found 44 percent more use cases for the technology. The startups that received this information had 1.9 times higher revenue and were 18 percent more likely to acquire paying customers.
๐ง You don't just inherit general intelligence โ ability in math and language is also more than half determined by genes
There has long been strong evidence that general intelligence is heritable. Now a large meta-analysis shows the same applies to abilities like math and language. The findings open up the possibility of using genetic profiles to tailor education to each child's cognitive strengths and weaknesses.
๐ AI scientist produces increasingly better papers โ and an AI system can review them as well as humans
The quality of scientific papers written by the AI system The AI Scientist increases predictably as the underlying AI models improve. An automated reviewer built by the same research group matches human reviewers' accuracy when evaluating scientific papers.
๐งฎ AI helps mathematicians solve problems that have been unsolved for decades
Since October, AI tools have helped move about 100 of Paul Erdลs' mathematical problems into the "solved" category. Large language models function as powerful research assistants that can find and combine existing mathematical results in new ways.
๐คจ Researchers question high-profile studies on microplastics in the human body
Seven studies reporting microplastics in the brain, testes, and other organs have been challenged by other researchers in scientific journals. Analytical techniques for measuring microplastics in tissue can produce false positive results because body fat can be confused with common plastics.
๐ฆพ AI scientist performs six months of work in one day
Kosmos can read 1,500 scientific papers and run 42,000 lines of analysis code in a single run. The AI system has already made seven discoveries in neuroscience, materials science, and statistical genetics.
๐ฆพ AI helps 1200 researchers develop new materials in global hackathon
More than 100 teams developed AI tools that can predict crystal structures, track medicines, and design new chemicals in just two days.
๐ฆ Scientists observe 'Hofstadter's butterfly' for the first time
Scientists have measured the energy levels of electrons in a new quantum material and discovered that they follow a fractal pattern, known as "Hofstadter's butterfly." It has been theoretically predicted since 1976 but has now been directly observed for the first time in a real material.
