Could humans build a tall tower or giant rope to space?
The movie Ad Astra shows a space antenna, a spindly structure reaching up into the stars. We look at what it would take to build something that big.

High-speed camera reveals the secrets of a legless larva’s leap
Research reveals how a blob of an insect can leap more efficiently than it crawls. Its body acts like a spring.

Chemists have created a ring-shaped form of carbon
A ring-shaped carbon molecule takes its place among buckyballs, carbon nanotubes and other odd forms of the element.

Americans consume some 70,000 microplastic particles a year
The average American consumes more than 70,000 microplastic particles a year. Scientists hope this estimate will spur others to look at health risks.

Sound ways — literally — to move and filter things
New technologies use sound waves to move and levitate objects. It’s not magic — it’s acoustophoresis.

If dark matter particles could kill us, they would have already
Dark matter is a mysterious substance. The fact that no one has been killed by it suggests it is relatively small and light.

Tiny new magnets are not only squishy but also liquid
Researchers have just created liquid droplets that behave like tiny bar magnets. The movement of these external magnets might help control robots and more.

Scientists Say: Big Bang
The Big Bang is the current theory about how our universe came to be. It began with a vast explosion of matter — a very Big Bang.
