What mechanisms underlie frequent and repetitive hair pulling and skin picking?

Comments written quickly after an article was published were more likely to contain hate and threats than those posted later. This is shown by a time analysis conducted by researchers at the University of Gothenburg of 38 million reader comments on The Guardian’s website.

As global insured losses continue to climb and climate-driven extremes reshape financial risk, the Natural Hazards and Catastrophes track within the Master of Professional Science (MPS) program at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science is preparing graduates for fast-growing careers in insurance, reinsurance, and risk analytics.

Amid intensifying global competition for technological leadership in secondary batteries, a major international platform for global collaboration and industry engagement has successfully concluded. The Korea Research Institute of Chemical Technology (KRICT, President Lee Young-kuk) announced that it successfully hosted the “2026 International Forum on Next-Generation Secondary Batteries” from February 5 to 6 at the Seoul Science and Technology Convention Center, with the participation of approximately 300 stakeholders from industry, academia, research institutes, and government.

A new method for cleaning household water supplies in rural communities in Nepal is being developed by an international team of scientists.

The solution removes harmful bacteria from the water by inserting non-toxic metal catalysts into containers which sit outside residents’ homes and feed their points of supply.

Billy Hudson, PhD, director of the Vanderbilt Center for Matrix Biology and the Elliott V. Newman Professor of Medicine, is receiving the Ellis Island Medal of Honor in 2026, following a unanimous decision by Ellis Island Honors Society (EIHS) Chairman Nasser J. Kazeminy and the EIHS Board of Directors.

During a January 2026 expedition aboard the Spanish polar research vessel Hespérides, MBARI researchers and an international team of collaborators from GEOMAR Helmholtz Centre for Ocean Research Kiel, Stockholm University, The University Centre in Svalbard, the University of Barcelona, the University of Haifa, and the University of Milano-Bicocca studied how a warming climate may be affecting seafloor processes in Antarctica. Funded by the Polar Research Infrastructure Network (POLARIN), this expedition conducted the first controlled-source electromagnetic surveys in Antarctica to understand how a rapidly warming polar environment impacts groundwater systems under the seafloor.

Cannabis affects us differently than alcohol. How do we know when it’s safe to drive? A recent study explores how cannabis use influences real-world driver behavior.

An unassuming metal barn erected recently at the southern edge of the University of California, Davis campus houses some advanced video technology for a uniquely UC Davis project. Leveraging UC Davis’ historic strengths in veterinary medicine and engineering, the Center for Animal Flight and Innovation is the only facility of its kind in the United States and one of very few in the world capable of capturing images of birds in flight in exquisite detail. It will use state-of-the-art technology to get new insights into how birds — specifically, hawks and other raptors — maneuver in the air.
