A giant asteroid will skim Earth in 2029—and it’s not us who should worry - Futura, le média qui explore le monde

October 13, 20263 min read Add Us On GoogleAdd SciAmScientists wonder: Is my AI stealing my ideas? Researchers are using AI as a sounding board throughout their work. But concerns are growing that companies may present users’ ideas as those of their modelsBy Peter Hall edited by Joseph HowlettScientists are becoming increasingly concerned about the privacy of their manuscripts in the wake of high-profile accusations that AI companies harvested uploaded documents. Who is Danny/ShutterstockRecently, controversy and accusations have followed artificial intelligence companies flexing their models’ research capabilities. When OpenAI claimed an internal model had solved one of math’s seven million-dollar problems, a mathematician at New York University insinuated that the company had stolen his progress, which he had shared with one of its chatbots. Weeks later the New York Times reported a similar story unfolding between Anthropic and a biologist at the University of Copenhagen regarding a group of enzymes. Despite this, scientists from all disciplines are opting to use these companies’ large language models.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.

Lawrence Livermore National Laboratory researcher Isaiah Santistevan led the development of three-dimensional simulations exploring how a nuclear device could deflect or disrupt an asteroid threatening Earth.

SpaceX's Dragon spacecraft docked with the International Space Station on October 15 and delivered more than 6,300 pounds of food, essential supplies and scientific equipment to the crew of Expedition 75. The cargo included equipment for manufacturing artificial retinas in microgravity, brain organoids, three-dimensional models of heart tissue and materials for studying a new type of glass. As ScienceDaily reports, Dragon docked with the space-facing port of the Harmony module at 10:27 a.m. Eastern Time. This is SpaceX's 35th commercial ISS resupply mission under a NASA contract. Research for medicineThe equipment for manufacturing artificial retinas is intended to help study the possibility of creating such structures in microgravity. Scientists hope these technologies may be useful for restoring vision on Earth in the future.3D models of heart tissue that reproduce important properties of the human heart were also sent to the station. They are planned to be used to improve methods for testing large numbers of potential medicines during future space missions. More current news is available on the UA. News Telegram channel Telegram.
