Two NOAA satellites saw a solar eclipse on Sept. 7 as the moon blocked out the sun mere hours before a lunar eclipse was seen on Earth.

In a recent study by Dany Coutinho-Nogueira and his colleagues, the remains of three non-adults from Cabeço da Amoreira were analyzed. The work is published in the journal Childhood in the Past.

Space changes you. It strengthens some muscles, weakens others, shifts fluids within your body, and realigns your sense of balance. NASA’s Human Research Program works to understand—and sometimes even counter—those changes so astronauts can thrive on future deep space missions.  …

Conducting a flyby mission to an interstellar object visiting our solar system is “feasible and affordable,” a new study finds. But orbiting such an interloper is a different story.

This butterfly can hatch planets.

Scientists have discovered that even short-term exposure to polluted air can speed up Alzheimer’s, worsening toxic protein buildup in the brain and accelerating memory loss. The research connects fine particulate matter (PM2.5) from sources like smoke and traffic directly to…

UC Berkeley researchers mapped the brain circuits that control growth hormone during sleep, uncovering a feedback system where sleep fuels hormone release, and the hormone regulates wakefulness. The discovery helps explain links between poor sleep, obesity, diabetes, and cognitive decline,…

Scientists discovered seven molecules in the blood linked to excessive daytime sleepiness, a condition that affects one in three Americans and raises the risk of heart disease, obesity, and diabetes. The study highlights the role of both diet and hormones,…
