Moderate calorie restriction lowered the immune protein C3, which appears to contribute to chronic inflammation during aging. Blocking C3 reduced age-related inflammation in mice, suggesting a possible way to reproduce some effects of calorie restriction without severe dieting.

NASA’s Roman Space Telescope has been enclosed in its Falcon Heavy launch fairing and is nearing launch. The mission could discover thousands of exoplanets while studying dark matter, dark energy and the universe’s accelerating expansion.

Simulations suggest that a roughly 320-meter asteroid hit Deimos at an angle, creating its large southern depression and spreading dust around the moon without destroying it. Observations from ESA’s Hera spacecraft support the impact scenario and indicate that Deimos is unusually porous and fragile.

A curated list of other prominent stories from this day.

DNA from a nearly 190-year-old museum specimen confirmed a distinct Himalayan pangolin species in Nepal and northern India. The finding could help conservationists identify the origins of illegally traded scales.

A Manhattan-sized ice island broke away from Greenland’s Petermann Glacier after years of widening fractures weakened its floating ice tongue. Scientists expect two additional large sections could detach, removing about 22 percent of the remaining tongue.

Scientists still do not fully understand why alcohol produces hangover symptoms. That uncertainty has not stopped companies from marketing remedies that claim to be backed by science.

Researchers found that indigo light, a wavelength largely absent from indoor LED lighting, completely prevented experimentally induced myopia in tree shrews. The result suggests that indoor lighting designed to better resemble sunlight might help protect developing eyes, though the effect has not yet been demonstrated in children.

In mice, early-life stress altered how DNA was packaged in brain cells, leaving stress-related genes more ready to activate later in life. Blocking that change prevented the adult animals from developing heightened anxiety and stress sensitivity.
