AI Advances Chemical Synthesis, While Researchers Grapple with Language Barriers and Unexpected Polar Bear Behavior
Recent developments across various scientific fields highlight the increasing role of artificial intelligence, challenges in scientific communication, and surprising findings in climate research. An AI system named MOSAIC has demonstrated expertise in chemical synthesis, while the preprint server arXiv is implementing a new language policy, and scientists are observing unexpected behavior in Norway's polar bear population.
Researchers have created an artificial intelligence (AI) system, MOSAIC, that simplifies and accelerates the process of chemical synthesis, according to a study published in Nature on January 19. The system recommended conditions that researchers were able to use to generate 35 compounds with the potential to lead to the discovery of blockbuster drugs and wonder materials. Chemical synthesis, the process of creating complex chemical compounds from simpler precursors, is often an arduous task for chemists, requiring them to sift through millions of known chemical reactions.
Meanwhile, arXiv, a prominent preprint server, announced that, starting February 11, all submissions must be written in English or accompanied by a full English translation. Previously, only an abstract in English was required. According to arXiv staff, the English rule will make moderation easier and maintain a broad readership. The decision raises questions about the role of AI translation tools in assisting researchers who do not speak English natively. Every month, more than 20,000 scientific manuscripts are posted on arXiv by authors from around the world.
In climate news, scientists are reporting unexpected findings regarding polar bears in Norway. Polar bears, often considered a symbol of the threat posed by climate change, are facing challenges as warming temperatures reduce the ice they rely on to hunt seals. Benji Jones, an environmental correspondent at Vox, reported on the surprising results from new Arctic research regarding the polar bear population.
In other news, American alpine skiing superstar Mikaela Shiffrin suffered a stab wound through her abdominal muscles in November 2024 during a World Cup race in Vermont. She struck a gate and somersaulted onto her back before crashing into protective netting. The injury occurred just seconds away from her milestone 100th World Cup victory. Shiffrin required surgery and rehab, but eventually made it back on the slopes.
Finally, research into autism spectrum disorder (ASD) has led to the creation of a large patient collection of human induced pluripotent stem (hiPS) cells, consisting of 70 hiPS cell lines representing 8 ASD-associated mutations, idiopathic ASD, and 20 lines from non-affected control individuals. These hiPS cell lines are being used to generate human cortical organoids to identify shared and distinct mechanisms of ASD-linked mutations, according to Nature.
