NYU Study Links GLP-1 Drugs to Male Hair Loss Risk

A new NYU Langone Health study has identified a genetic connection that may help explain why some men experience hair loss while using GLP-1 medications such as Ozempic, Wegovy and Zepbound. Researchers found that men already genetically predisposed to androgenetic alopecia, commonly known as male-pattern hair loss, could face an additional 7 percent risk associated with GLP-1 activity. The findings go beyond previous theories that hair shedding among people taking the medications is primarily caused by rapid weight loss. Researchers say additional studies are needed to understand the biological mechanism and determine whether a similar genetic relationship exists in women.

NYC Schools Pause Generative AI for Younger Students

New York City is putting new limits on how artificial intelligence and other technology are used in public school classrooms, with a one-year moratorium on student-facing generative AI for students from 2-K through eighth grade. The policy, which will affect nearly 600,000 students, also establishes screen-time guidelines while taking a more controlled approach to AI for older students. High school students will receive AI literacy instruction, and a limited number will participate in supervised pilot programs designed to test educational uses of the technology. A new Technology in Schools Coalition will evaluate the policy and pilots during the 2026-27 school year and make recommendations about the future role of AI in NYC schools.

Mount Sinai Launches Genomic AI Research Center

Mount Sinai’s Icahn School of Medicine has established a new research center that will explore how genetics and the microorganisms living in the human gut may work together to influence disease development and patient outcomes. Using advanced sequencing technologies and artificial intelligence, researchers plan to analyze complex biological data in search of patterns that could help explain why diseases progress differently among patients and why individuals can respond differently to the same treatments. Initial research will concentrate on Alzheimer’s disease, Parkinson’s disease and gastrointestinal cancers, with the broader goal of supporting more personalized approaches to disease risk, diagnosis and treatment.

Columbia-Led XENONnT Detects Solar Neutrinos

A research team led by Columbia University physicist Elena Aprile has reached a major milestone with the XENONnT experiment, detecting solar neutrinos at energies lower than previously achieved through direct observation. Researchers measured neutrinos produced by the fusion reactions that power the Sun by identifying their interactions with electrons inside XENONnT's ultra-pure liquid xenon detector. The experiment, built primarily to search for dark matter, recorded the signal at the level of statistical significance used by particle physicists to establish a discovery. The findings demonstrate how technology developed for dark matter research can also advance the study of neutrinos and other extremely rare particle interactions.

Voices of NYC: AI Starts With Teacher Learning

As schools rapidly adopt artificial intelligence tools, the conversation often centers on how students will use them. In this Voices of NYC commentary, Brooklyn College professor Dr. Sonia Murrow argues that the greater challenge is ensuring teachers receive the ongoing support needed to adapt their instruction. Drawing on interviews with New York City educators, she contends that while AI technology is advancing quickly, professional learning has not kept pace. Rather than relying on occasional workshops, she makes the case for sustained collaboration that helps teachers thoughtfully integrate AI while preserving critical thinking and meaningful learning in the classroom.
