NASA has successfully tested a system that allows satellites to navigate without GPS by using other spacecraft and debris as landmarks in orbit. In just three days, FALCON also improved the known orbits of more than 200 space objects completely autonom…

Moderate calorie restriction lowered an immune protein called C3 that appears to help drive chronic inflammation as the body ages. Blocking the same protein reduced age related inflammation in mice, raising the possibility that future treatments could …

DNA from a nearly 190-year-old museum specimen has helped scientists confirm a distinct Himalayan pangolin species hiding in plain sight in Nepal and northern India. The discovery could give conservationists a powerful new way to trace illegally traded…

A Manhattan-sized ice island has broken away from Greenland’s Petermann Glacier after years of growing fractures weakened its floating ice tongue. Scientists expect two more huge sections could soon detach, potentially removing about 22 percent of the …

Britain’s postwar sugar rationing created a rare natural experiment that let researchers examine how early sugar exposure might affect health decades later. People who experienced more rationing during their first 1,000 days had lower rates of several …

A compound found in turmeric may help protect blood vessels from some of the damage caused by Type 1 diabetes. In rats, curcumin reduced inflammation, improved cellular signaling, and restored vascular health to levels resembling those of nondiabetic a…

NASA’s Roman Space Telescope is now enclosed inside its Falcon Heavy fairing and nearly ready for launch. Its mission could uncover thousands of exoplanets while helping scientists investigate dark matter, dark energy, and the accelerating expansion of…

A single asteroid impact may explain two of Deimos’s most puzzling features: its huge southern depression and unusually smooth, dusty surface. Simulations suggest a roughly 320-meter asteroid struck the Martian moon at an angle, throwing debris around …

A wavelength of light largely missing from indoor LEDs may play an important role in protecting developing eyes from nearsightedness. Researchers found that indigo light completely prevented myopia in tree shrews, whose eyes share important similaritie…

Early-life stress may physically alter how DNA is packaged in the brain, leaving stress-related genes primed to activate more easily years later. In mice, researchers were able to block this effect, preventing the heightened anxiety and stress sensitiv…

A low-carb diet may raise LDL cholesterol much more sharply in people who are genetically predisposed to high cholesterol, particularly when they consume lots of saturated fat. The findings could help explain why people following seemingly similar diet…

Three forgotten Assyrian kings may have been hiding in plain sight for more than 2,700 years. By piecing together clues from tablets, inscriptions, and an ancient statue, researchers argue that these rulers were omitted from the famous Assyrian King List.
