What's up in
Science
Physics, climate, planetary science, and the research that shapes how we understand the universe and our place in it.
Glass frogs can turn much of their body see-through while they sleep by pulling almost all of their red blood cells out of circulation and storing them in their liver, then releasing them again when they wake and need to move.
Veterinary researchers found that between 64% and 92% of cats over the age of 10 have arthritis — and because cats are built to conceal pain, most owners have no idea
The human body gives off a faint glow of visible light, produced by ordinary chemical reactions inside living cells. It is real light, but it is far too weak to see: roughly a thousand times below the sensitivity of the naked eye, so to us the body appears completely dark.
Octopuses have three hearts and blue blood that carries oxygen using a copper-based protein rather than iron, and because the heart that supplies the body stops beating whenever they swim, many bottom-dwelling octopuses tend to crawl along the seafloor instead of swimming for long stretches.
In 1977, a radio telescope in Ohio called Big Ear picked up a 72-second signal so strong and so cleanly from the direction of Sagittarius that the astronomer on duty circled it in red ink and wrote 'Wow!' in the margin, and nearly fifty years later nobody has ever heard it again.
The sun accounts for about 99.86% of all the mass in the solar system, which means every planet, moon, asteroid and comet combined is little more than a rounding error.
Naked mole-rats age so slowly, resist cancer so well and survive oxygen loss so strangely that researchers now study them as one of nature’s best clues to human ageing.
Antarctica is the largest desert on the planet, because a desert is defined by how little water falls from the sky rather than by heat, and almost nothing falls on the frozen continent.
The strange truth about today's most powerful AI is that even the people who build it cannot fully explain why it works, which means much of modern technology now rests on tools we can use far better than we can understand.
Some Australian Aboriginal stories may remember coastlines that vanished beneath the sea over 10,000 years ago. Researchers think they could be among humanity’s oldest surviving true stories.
