Four private astronauts are orbiting Earth's poles in SpaceX's Fram2 mission. One of them, Chun Wang, shared a video showing how Antarctica looks from space. "Hello, Antarctica...Unlike previously anticipated, from 460 km above, it's only pure white, no human activity is visible," he added. The video was captured when the crew opened the Dragon's Cupola, a domed, all-glass observation window.

NASA confirmed that asteroid 2024 YR4, which could unleash enough force to obliterate a city, is no longer on track to hit Earth but may strike Moon in 2032. Detected in December 2024, its Earth impact risk dropped from 3% to near zero. The James Webb Telescope will study it again in May 2025 before it moves into deep space.

Researchers have developed a novel metamaterial that enables precise detection of trace molecules. By tuning its structure to achieve over 98% absorption of infrared light at specific molecular fingerprints, this technology dramatically enhances the sensitivity of sensors. This breakthrough is set to revolutionise environmental monitoring and rapid medical diagnostics for pollutants.

Indian Air Force's Shubhanshu Shukla, who will become the first Indian astronaut to fly to International Space Station (ISS) aboard SpaceX Dragon as part of Axiom Mission 4, is expected to depart in May. Shukla, with over 2,000 flying hours, will serve as mission pilot aboard the SpaceX Dragon and it'll take off from NASA's Kennedy Space Center in Florida.

SpaceX and US Air Force's project to test hypersonic rocket cargo deliveries from a remote atoll in the Pacific Ocean could harm seabirds. According to University of Texas wildlife biologist Ryan Rash, the rocket's sound could scare birds away from their nest and make them "anxious and unsure" of returning. "This could result in a loss of generation," added Rash.

A new study published in Journal of the American Heart Association found that people who exercise only on weekends still receive similar health benefits as those who spread workouts throughout the week. These health benefits include reduced risk of death from cardiovascular disease, cancer, and all causes, compared to those who don't meet recommended 150 minutes of weekly physical activity.

Even 2 days of exercise a week can lower risk of death from all causes: Study

Researchers at Indian Institute of Science (IISc) have developed a new method to repair space bricks using bacteria. The researchers found that using a soil bacterium called Sporosarcina pasteurii with guar gum and lunar soil simulant, they were able to repair cracked bricks. The bacterium created calcium carbonate, which filled up the cracks, and adhesives, which bound soil particles together.

Earthquake victims can survive for a week or more if their injuries aren't too severe and weather conditions are not too extreme, according to experts. Most rescues occur within the 24 hours after a disaster, with chances of survival decreasing with each day after that. Most victims get severely injured or buried by falling stones or other debris.

How long can trapped victims survive after an earthquake?

Four rocky planets much smaller than Earth have been discovered. They orbit Barnard's Star, the next closest to ours after the three-star Alpha Centauri system. Barnard's Star is the nearest single star. These planets orbit their star much too closely to be habitable. The closest planet's 'year' lasts a little more than two days.

In the artificial intelligence industry, many women leaders have risen to prominence. From Timnit Gebru's advocacy for diversity and ethics in AI to Meghana Jagadeesh's innovative vision, they have played pivotal roles in shaping the future of AI. More remarkable women in AI, like Mira Murati, Allie Miller, and Rana el Kaliouby, have left an indelible mark on the industry.
