Scientists thought they knew how this 70-year-old leukemia drug worked

A 70-year-old leukemia drug is still revealing new secrets. Researchers found that removing a protein called NUDT5 protected cells from the drug, even though simply blocking the protein had little effect. The unexpected result points to a hidden cellular role that could help explain why people respond differently to certain leukemia treatments.

Aging muscles may be losing strength for a reason scientists missed

A newly identified breakdown in communication between nerves and muscles could help explain why people lose strength as they age. Researchers were able to improve muscle strength in an animal model by targeting a key protein, raising hopes that some age-related weakness could eventually be treated.

Researchers build microscopic DNA 'sails' to pull molecules apart

Across every cell in the body, molecules are constantly pulling, gripping and releasing under mechanical strain. That force often decides whether a drug sticks to its target, whether a cell holds its shape or whether a disease takes hold.

Scientists find two tiny new snails with shells that close like doors

Scientists discovered two tiny new snail species in Montenegro, showing that even Europe still holds animals unknown to science. One lives in the threatened Komarnica Canyon, where a proposed hydropower reservoir could destroy habitat before its full biodiversity is understood.

Climate change: Laws and policies must change to prevent future statelessness

Australia and other nations should amend laws and practices to address the needs of millions of people expected to move because of climate-related hazards, according to a new report by the Peter McMullin Centre on Statelessness and the United Nations High Commissioner for Refugees (UNHCR).

Q&A: Why should colleges promote student physical activity?

Every fall in the United States, millions of young people move to college campuses, away from home for the first time. During this transition, they typically develop new social networks and routines as they learn to live on their own. One of the most important routines college students can intentionally develop is regular physical activity, according to Melissa Bopp, a professor of kinesiology at Penn State.

These massive stars could explain Webb’s strangest galaxies

Hubble observations of massive stars in metal-poor dwarf galaxies are revealing clues to why the early universe looks so unusual. Researchers found that stellar winds weaken sharply at extremely low metallicities, potentially allowing massive stars to retain more material and evolve in unexpected ways. The team also found large differences in iron abundance, a key ingredient in stellar winds and supernovae.
