What Are You Doing With Your Life? The Tail End

Wrapping your mind around your life is pretty hard, because you are up to your neck in it. It's like trying to understand the ocean while learning how to swim. On most days you are busy just keeping your head above water. So it is not easy to figure out what to do with your life and how to spend your time.

It’s easy to get lost. So let us take a step back and take a look at your life from the outside.

Only Have Your First Vaccine Dose So Far? Here's The Data on How Protected You Are

More than 147 million Americans and more than 34 million Britons have received their first dose of a two-shot COVID-19 vaccine.

The data for how well the vaccines work after one dose isn't always clear cut – it depends on what you're measuring, and when you're measuring it.

This is how much protection one shot of each vaccine gives you, based on the best data we have so far...

Entropy: The Heat Death of The Universe

As the arrow of time pushes us forward, each day the universe inches closer to maximum entropy. And when that does happen, the lights just might turn back on, and for all we know, we might just end up back at square one.

The Formation Story of Our Galaxy Just Got Less Violent, But More Interesting

Ever since the Gaia satellite began mapping the Milky Way in three dimensions with the highest precision yet, we've been learning a lot about our home galaxy's violent past.

The scrappy cannibal has collided with, and subsumed, multiple other galaxies over its 13.6-billion year lifespan. The largest of these, the Gaia-Enceladus dwarf galaxy (AKA the Gaia Sausage), took place around 10 billion years ago, and was thought to be responsible for a curious feature of the Milky Way's structure called the thick disk...

Radical Discovery Suggests The Maximum Human Lifespan Is 150 Years of Age

We dream of a time when modern medicine will allow humans to live far beyond the lifespans we know today. But is there an upper limit of what's biologically possible?

Yes, according to a new study, which suggests the maximum human lifespan probably tops out at about 150 years of age.

The research taps into the idea of biological aging or senescence – how quickly our bodies deteriorate, which may or may not match our chronological age (how many birthdays we've celebrated)...

New Dark Matter Map Shows The Bridges Between The Milky Way And Nearby Galaxies

A new map of dark matter made using artificial intelligence reveals hidden filaments of the invisible stuff bridging galaxies.

The map focuses on the local universe — the neighborhood surrounding the Milky Way. Despite being close by, the local universe is difficult to map because it's chock full of complex structures made of visible matter, said Donghui Jeong...

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...
