Dogs Can Detect Over 90% of COVID-19 Cases, Even Asymptomatic Ones
Dogs can be trained to detect more than 90 percent of COVID-19 infections even when patients are asymptomatic, according to new research available in preprint, which authors hope could help replace the need to quarantine new arrivals.
Using their remarkable sense of smell - which can pick up the equivalent of half a teaspoon of sugar in an Olympic-sized swimming pool - dogs have already shown that they can sniff out maladies such as cancer, malaria and epilepsy.

How Exactly Do Planetary Flybys Work?
Gravity assists, sometimes called flybys, are a big part of space exploration. These precision maneuvers involve harnessing a planet’s gravity to accelerate and direct a spacecraft to some far-flung destination so the spacecraft can go further without a big and heavy propulsion system. It’s a key element in both human and robotic space explotration...

Gene Therapy Partially Restores Vision in Blind Patient in First Case of Its Kind
A blind man who lost his sight to a neurodegenerative eye disease decades ago has had his vision partially restored, thanks to a first-of-its-kind experimental gene therapy.
For those people and their families, recent advancements in optogenetics could be a source of new hope for restored vision – although it's worth emphasizing this approach is still very much in the experimental stage, with practical treatments likely to be years away....

Scientists Discover a New Type of Biochemical That Could Be in All Life on Earth
The wonderful mess of molecules that make up living things is so complex, biologists have overlooked an entire class of them – until now. This missed bit of biochemistry is neither rare nor hard to find; it's just no one had thought to look for it before.
"This is a stunning discovery of an entirely new class of biomolecules," said Carolyn Bertozzi. "It's really a bombshell because the discovery suggests that there are biomolecular pathways in the cell that are completely unknown to us."

The Long-Forgotten History of the British Moon Spacesuit
Decades before NASA's Apollo program, the British Interplanetary Society wanted to go to the moon: in a spacesuit that looked like a suit of armour.

In the Blink of an Eye: Space in an Instant
When we look up at night, the universe seems pretty quiet. But that perspective is an illusion; in reality, there are millions of world-shattering events happening every instant across the cosmos. This short film explores just how much is going on every moment in our ridiculously enormous universe.
In the fraction of a second it takes to blink your eyes, thousands of stars will be born, hundreds will explode and die, millions of planets will form, and our universe will expand by half a million kilometers in diameter.
And these numbers only account for the observable universe -- not for what could be happening beyond, where some scientists believe there could be an infinite expanse of space.
Think next time you blink.

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)...

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.
