A new study highlights a novel idea to clean up this orbital mess using bidirectional plasma thrusters improved …

An asteroid that entered over France and exploded at quite a low altitude has uncovered a new impact risk that Earth’s planetary defences might not be ready to fight. Asteroid 2023 CX1 burst into a fireball after disintegrating in the sky at an altitude of around 28 kilometres. According to a research that looked into the asteroid explosion, the asteroid …

Here’s what you’ll learn when you read this story: The discovery of salt giants in the Dead Sea—formed from a perfect mixture of conditions in the terminal lake—presents a prime opportunity to study how these geological formations coalesce. Researchers behind a new study analyzed these salt giants and compared them to similar formations in the Mediterranean, which faced its own …

We’ve known for quite some time that molten rock gouged enormous tunnels into the surface of the Earth, the Moon, and Mars. In fact, scientists have proposed that the vast lava tubes under the surface of the Moon and Mars could one day serve as homes for space colonists that provide shelter from space radiation and micrometeorite strikes. Now, as …

Vascular dementia—damage from the brain’s smallest vessels—may be more varied, and more entangled with Alzheimer’s, than assumed. Credit: Shutterstock A new model of vascular dementia reveals hidden disease processes and raises urgent questions about the role of microplastics in brain health. Vascular dementia, a form of cognitive decline caused by disease in the brain’s small blood vessels, is common but …

NEW YORK (AP) — Scientists have discovered a new dinosaur from Argentina with powerful claws, feasting on an ancient crocodile bone. The new find was possibly 23 feet (7 meters) long and hailed from a mysterious group of dinosaurs called megaraptorans. They prowled across what’s now South America, Australia and parts of Asia, splitting off into different species over millions …

In 2022, NASA intentionally rammed a spacecraft into a small asteroid at 14,000 mph, knocking it off course. The goal was to demonstrate a proof of concept for keeping humanity safe from a space rock heading toward the Earth. Now a group of scientists, including ones from NASA, is exploring options for a different near-Earth space rock, dubbed 2024 YR4, …

A team of researchers from Stanford University and the Arc Institute in Palo Alto, California say they’ve created viruses with AI-designed DNA that can target and kill specific bacteria. And these aren’t just simulated possibilities — they’re real and already slaying germs in the lab. The work, published in a new study awaiting peer-review, is a compelling testament to the …

In the heart of Yellowstone National Park, scientists have just drawn the clearest underground map to date of one of the most watched supervolcanoes on Earth — and it’s revealing some surprises. A recent Nature study, led by USGS researchers in collaboration with Oregon State University and the University of Wisconsin-Madison, used electromagnetic imaging to scan Yellowstone’s subsurface like never …
