An analysis of 2,884 exploding stars found evidence that dark energy, which drives the universe's accelerating expansion, may have changed over time. The result puts pressure on the standard cosmological model, which treats dark energy as constant.

Global timekeeping has relied on occasional leap seconds for more than five decades to keep atomic clocks aligned with the Earth's irregular rotation. International officials have now moved toward ending that system, with leap seconds expected to be phased out by 2035.

Across five European countries and 37 bird species, birds consistently fled sooner when approached by women than by men. Researchers have not identified the cues driving the difference.

Researchers captured virus-like particles assembling step by step through trial and error, identifying a molecular transition that makes the process faster and more reliable. The findings could inform antiviral strategies and vaccine design.

Researchers developed a laser-based microscope that sharply improves the visibility of cellular structures, including proteins that are difficult to capture with conventional electron microscopy. The technology could help map how molecular machines operate inside cells.

Researchers observed honey bees chasing wild pollinators away from flowers and monopolizing food sources. They warn that warmer conditions and growing honeybee populations could intensify the competition.
