What has the magnetic properties of a solid magnet, but the mechanical properties of a liquid? If you answered 'nothing,' you're wrong - because engineers have just created just such a substance, by using a modified 3D printer.

When toddlers are given two options by their parents, their final pick may have less to do with choice and more to do with imitation.

The Silurians are a species of lizard-like creature that appeared in the cult science fiction TV show Dr. Who. They achieved industrial expertise about 450 million years ago, long before humans evolved on Earth. The Silurians are fictional, of course. But…

Which came first - peptides or enzymes?

We all know sharks have had a bit of an undeserved bad rap (thanks Jaws!). But if you're one of those people who find sharks scary, this newly identified species of pocket shark might just change your mind.

Unless you suffer from a neurological disorder, such as schizophrenia - or like to dabble in psychedelics - chances are you don't spend much time worrying about seeing things that aren't there.

LightSail 2 has successfully deployed its solar sails. Shortly after 12:00 pm PST (19:00 UTC) The Planetary Society tweeted that the sails were deployed, and that the spacecraft was sailing with sunlight.

When it comes to our physical world, scientific research indicates that size really does matter.

Starhopper has completed its first untethered flight ever, simultaneously a small step for the awkward prototype and a giant leap for SpaceX’s Starship/Super Heavy program as the next-gen launch vehicle is carried into a new phase: flight testing. Despite…

Just 7,800 light-years from Earth, two dead stars have been discovered orbiting each other at record-breaking speeds. So close is their orbit, that astronomers expect to detect gravitational waves from this pair in a matter of years, when we turn o

Research on robotic prostheses is coming along in leaps and bounds, but one hurdle is proving quite tricky to overcome: a sense of touch. Among other things, this sense helps us control our grip strength - which is vitally important when it comes t

If this headline looks familiar to you, that's because we wrote an almost identical one in 2016. Except back then, we were freaking out because we'd used a year's worth of Earth's resources by August 8. Now, three years later, we've accomplish

The Planetary Society has been busy recently. On June 25, its LightSail 2 launched into orbit; just last week on July 24, the craft opened its sails successfully, a key stage of its mission to demonstrate solar sailing in practice.

Back in 1976, the late Carl Sagan sat down on the Tonight Show with Johnny Carson to talk about a new form of space propulsion called solar sailing. Four decades later, and The Planetary Society has officially demonstrated this "tremendously exciti

If a person's liver starts failing, the only medical option we currently have is to replace this vital organ, either partially or fully. But now, the discovery of a new type of liver cell has scientists hoping for a less invasive and risky&nbs

Researchers have developed artificial cells that can respond to external chemical forces, just like real ones do. This exciting step could get us closer to using synthetic biological structures in real-world situations, such as targeted drug delive

Black holes can get pretty big, but there's a special class that is the biggest of the big, absolute yawning monster black holes. And astronomers seem to have identified an absolute specimen, clocking in at 40 billion times the mass of the Sun.
