Scientists Want To 3D Print Bones in Your Body

For the first time ever, scientists have figured out a way to 3D print bones using living cells. A team at UNSW Sydney has developed a new technique that's taken us one step closer to directly 3D printing bones into a human body.

Here's How The Brain Reboots Itself After The Deep Sleep of Anesthesia

You may well have spent hours wondering what your laptop could possibly be taking so much time over as it boots up, and now scientists have asked the same question of the human brain: How exactly does it start up again after being anesthetized, in a coma, or in a deep sleep?

Space Debris Has Hit And Damaged The International Space Station

A piece of space debris too small to be tracked has hit and damaged part of the International Space Station - namely, the Canadarm2 robotic arm.

The instrument is still operational, but the object punctured the thermal blanket and damaged the boom beneath. It's a sobering reminder that the low-Earth orbit's space junk problem is a ticking time bomb...

Ingenuity survived in-flight anomaly on Mars | Flight 6 highlights

NASA's Ingenuity helicopter experienced an anomaly during its sixth flight on Mars on May 22, 2021 but landed safely. It "began adjusting its velocity and tilting back and forth in an oscillating pattern," after the first 150-meter leg of the flight, according to NASA.

Colossal Flare Could Be First Evidence Energy Can Be Extracted From Black Holes

The popular conception goes that nothing can escape from a black hole. Once something passes the event horizon - the so-called point of no return - it stays there, forever, bound by a gravitational field not even light can escape.

But a rotating black hole generates vast amounts of energy, which, theoretically, can be extracted from the ergosphere, a region that sits just on the outside of the event horizon. This has been shown both theoretically and experimentally - and now a team of astrophysicists has found what they believe is observational evidence for it...

This 2D Material Is Way Tougher Than Graphene, And Scientists Are Excited

A two-dimensional material with similar physical properties to graphene has now turned out to blow graphene out of the water in terms of toughness.

The material is called hexagonal boron nitride (h-BN), and it's so resistant to cracking that scientists are gobsmacked. The finding flies in the face of the fundamental denoscription of fracture mechanics that scientists have been using to predict and define toughness since the 1920s...

We're Going Back to Venus! NASA Announces Two New Missions by 2030

NASA announced two new missions to Venus on Wednesday that will launch at the end of the decade and are aimed at learning how Earth's nearest planetary neighbor became a hellscape while our own thrived.

"These two sister missions both aim to understand how Venus became an inferno-like world, capable of melting lead at the surface," said Bill Nelson, the agency's newly-confirmed administrator...

In Surprise Discovery, Astronomers Find Huge Star Cluster in Our Cosmic Backyard

A huge cluster of stars has been found lurking in the Milky Way, just a relatively short cosmic distance from our own Solar System.

Now around 75 million years old, the open cluster Valparaíso 1 is estimated to have contained around 10,000 solar masses' worth of stars when it first blazed into existence...

Astronomers May Have Just Detected a New Magnetar!

A new discovery could soon be raising the total number of confirmed magnetars to 25.
On 3 June, a brief X-ray burst close to the galactic plane caught the attention of the Swift Burst Alert Telescope (BAT). Follow-up observation and analysis seem to confirm that it was emitted by a previously unknown magnetar, now named Swift J1555.2-5402...

NASA’s InSight Mars Lander Gets a Power Boost

The spacecraft successfully cleared some dust off its solar panels, helping to raise its energy and delay when it will need to switch off its science instruments.

The team behind NASA’s InSight Mars lander has come up with an innovative way to boost the spacecraft’s energy at a time when its power levels have been falling. The lander’s robotic arm trickled sand near one solar panel, helping the wind to carry off some of the panel’s dust. The result was a gain of about 30 watt-hours of energy per sol, or Martian day...
