SpaceX's Starship rockets are grounded pending investigation after test flight

A new study of British wrens has provided new insights into the inner workings of "island syndromes," according to research led by the University of Birmingham. The paper, published in the Evolutionary Journal of the Linnean Society, reveals that different subspecies of island wrens are evolving independently, with the team finding particularly strong evidence of "island gigantism" in two of the studied populations.

Happy, a Bronx Zoo elephant who gave researchers new insight into the animal's behavior and became the crux of a closely watched animal rights case, has been euthanized at age 55, the zoo said Wednesday.

An irreversible shift in the chemical makeup of the Arctic Ocean driven by climate change is disrupting the region's food chain, a study suggests. Widespread loss of Arctic sea ice has led to a sharp fall in levels of a key nutrient, affecting populations of plankton, fish, seabirds and marine mammals, say researchers. Their analysis reveals that exposure to sunlight of vast shallow regions of the ocean previously covered by ice fuels a process that breaks down the nutrient—nitrate—and removes i

Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers have used two techniques—high-speed temperature mapping and artificial heating—to observe how heat dissipates from living cells and similar-sized artificial, fluid-filled sacs (liposomes). While heat dispersed quickly from the artificial liposomes as expected, cells cooled significantly more slowly due to other biomolecules within the ce
