Spending time in space might sound thrilling, but it takes a serious toll on the human body. Weightlessness affects everything from muscles to blood flow. Hence, before astronauts head to the Moon or Mars, scientists must find ways to reduce the physical effects of long-term space travel....

In the summer of 2014, millions of people worldwide dumped buckets of ice water over their heads and challenged others to do the same. But this was not just for fun — they were taking on the Ice Bucket Challenge. The campaign, which went viral on social media, aimed to raise awareness and funds for ALS research, also known as Lou Gehrig’s disease. It raised an impressive $115 million for the ALS Association in just a few months....

On April 23, 2025, the Philadelphia Zoo introduced four female hatchlings of the critically endangered Western Santa Cruz Galápagos tortoises to the public. The new arrivals were named Dorothy, Rose, Blanche, and Sophia — after characters from the iconic television series The Golden Girls. They are the first of their kind to be born at the zoo in its 150-year history. Prior to this, there were only 44 Western Santa Cruz tortoises in US zoos, including three at Philadelphia....

Just when it seemed every color under the sun had been named, researchers at the University of California, Berkeley, have identified a new one. Called “olo,” this shade lies outside the normal range of human vision. It can only be seen under specific conditions using a laser. The five people who have seen "olo" describe it as a "blue-green of unprecedented saturation."...

Sharks have always been considered silent swimmers. Unlike most fish, these top ocean predators lack sound-producing organs. But recent research suggests this might not be true for all sharks. At least one species produces noise, challenging our understanding of these stealthy hunters....

One of the biggest challenges for long-term stays on the Moon is creating safe shelters for astronauts. Researchers have long believed that lunar caves might be the answer. These natural shelters could protect astronauts from the extreme temperature swings and constant exposure to space radiation. They might even have water ice. However, finding such caves had proved elusive....

When a 5.2 magnitude earthquake struck Southern California on April 14, 2025, a camera at the San Diego Zoo Safari Park captured a powerful display of animal instinct. As the ground shook, three African elephants quickly formed a protective circle around the two young calves. Their reaction offers a rare glimpse into the mammals' natural defense strategy....

Earth Day 2025 marks the 55th anniversary of the global environmental effort that began on April 22, 1970. The first Earth Day united 20 million Americans — about 10% of the US population at the time — to demand environmental protections....

A glowing green comet is captivating skywatchers across the Northern Hemisphere. Comet C/2025 F2 (SWAN) was first spotted by amateur astronomer Michael Mattiazzo on March 29, 2025. He discovered it while looking through images from the Solar Wind Anisotropies camera aboard NASA's Solar Heliospheric Observatory. Since then, the comet has been seen multiple times with the help of telescopes....
