👑 Wir heben einen Schatz für die #Forschung: Bisher wird das menschliche Gewebe, das bei OPs und medizinischen Engriffen anfällt, meist wissenschaftlich ungenutzt entsorgt. Mit dem Aufbau einer Primary Tissue Pipeline wird die #CharitéBerlin Forschenden den Zugang zu dem besonders wertvollen lebenden Gewebe nun erleichtern. Das soll die Qualität der Forschung verbessern – und geht so nur an einer Universitätsmedizin ✌️.

People have been observing galaxy NGC 6505 for 140 years, but only now noticed an "Einstein ring" at its center. There, gravity has bent and magnified another, more distant galaxy into a delicate ring of light.

The universe is full of beautiful, hidden surprises.

Rice causes ~12% of methane emissions or 1.5% of global greenhouse gas emissions.

Researchers in China and Sweden cross-bred a variety which could reduce CH4 by 70% while doubling yields!

But it won't grow everywhere, and the scientists have just started registering it.

Rice paddies, like cows, spew methane. A new variety makes them a lot less gassy.

Rice plants are a big source of methane, a potent greenhouse gas. Scientists just developed a strain that cuts those emissions by 70 percent.

A reminder that humans are capable of great acts of wonder when we work together & embrace knowledge.

An international team of astronomers has discovered swarms of cold comets circling 74 nearby stars -- and got clear pictures of these "exocomet belts."

Even fish get lonely? A solitary sunfish at an aquarium in Japan lost its appetite after the facility closed for renovations. So staff put life-size photos of humans outside the tank. The fish seemed to improve!

Sunfish that got sick after aquarium closed has recovered — thanks to human cutouts

A solitary sunfish at an aquarium in Japan lost its appetite, began banging into the side of the fish tank and appeared unwell days after the facility closed last month for renovations.

William Herschel discovers Titania and Oberon, two moons of Uranus.

Orbiting at a much greater distance from Uranus are the ten known irregular moons. The planet's magnetosphere is highly asymmetric and has many charged particles, which may be the cause of the darkening of its rings and moons.

How to catch the Geminids, one of the strongest meteor showers of the year.

@AssociatedPress reports: "The shower often produces meteors with a distinctly more yellow glow, likely due to the unusual origin material, said Sally Brummel, planetarium manager at the University of Minnesota’s Bell Museum."

How to catch the Geminids, one of the strongest meteor showers of the year

The Geminids are among the few major meteor showers to come from asteroids, and this year they will peak on Friday. The shower often produces meteors with a distinctly more yellow glow than other meteor showers that originate from comet debris.

Taking a break from awful things:

Scientists taught rats to drive cars. The rats quickly learned to rev the engine and take longer routes just for fun.

Bonus: Watch the researcher do a little happy leap when the rat gets into the car.

Carl Sagan would've turned 90 today. Reading 'The Demon-Haunted World' as a teenager profoundly shaped the way I think today. Almost 30 years later the book remains (sadly) relevant...

We knew it was going to happen, but the Voyager space probes are getting creaky in their old age.

NASA just had to reactivate Voyager 1's S-band transmitter for the first time in 43 years after a communication breakdown.

#PPOD: This photograph, taken by astronaut Matthew Dominick while peering out a Dragon Endeavor window, shows red and green aurorae streaming by Dragon Freedom which was docked to the front of the International Space Station. The Sun is still at solar maximum, with numerous flares and coronal mass ejections causing gorgeous aurorae even at lower latitudes. The different colors indicate different altitudes above the Earth's surface. Credit: Matthew Dominick/NASA

#PPOD: This stunning photograph captures the most violent moment during an eruption of the Calbuco volcano in Chile. Volcanic lightning occurs in the plumes of eruptions when volcanic ash particles collide, generating static electricity. Additionally, water vapor in the plume condenses and freezes as it rises, adding ice to the mix. And voila! The eventual electrical discharge causes lightning.

Happening now over your head: NASA’s Advanced Composite Solar Sail System has spread its wings.

The satellite, launched in April, just unfurled an 80-square-meter sail that will use sunlight to adjust its orbit. For now we just have an illustration; onboard photos are coming on Sept 4.

I really love this description of a retracted study: not only does it explain what was retracted (turns out men don't generally divorce their sick wives), but also it covers what the error was (a coding problem treated people who left the study as divorced) how it all went down (someone tried to replicate, asked for data and didn't get the same analysis. Contacted the authors and they were horrified and immediately worked to retract).

It's a really nice story of why replication matters and how to be good at science. This is how I was taught science should work, but I rarely come across such good retrospectives.

“To our horror”: Widely reported study suggesting divorce is more likely when wives fall ill gets axed

A widely reported finding that the risk of divorce increases when wives fall ill — but not when men do — is invalid, thanks to a short string of mistaken coding that negates the origina…

Here's an old pic I took back in 2019, showing the UT4 telescope at ESO's Paranal Observatory shooting its four mighty lasers. These lasers excite sodium atoms high up in the atmosphere, creating fake "stars" that we monitor in real time to measure and correct atmospheric turbulence, thus yielding very sharp images.

The two faint smudges flanking UT4 are he Andromeda (left) and Triangulum (right) galaxies.
