It’s infuriating to me that I need to evaluate media to determine whether it’s AI generated now. The great “time saver” technology wastes incalculable time and energy for people who want to retain their grasp on reality

With all the nonsense around genAI over the past few years, it's easy to forget that machine learning can be a useful tool, such as in this research where it was used (alongside more traditional chemical analysis) to detect signs of ancient life. carnegiescience.edu/chemical-evi...
Chemical evidence of ancient life detected in 3.3-billion-year-old rocks
New study shows life’s signature still exists in rocks long after the original biomolecules are gone.

Wir denken linear: "2 Grad ist ja kaum mehr als 1,5 Grad."

Die Natur reagiert exponentiell.

​Bei den Korallenriffen ist dieses "halbe Grad" der Unterschied zwischen Dezimierung und Auslöschung.

​Das halbe Grad hat entschieden, dass unsere Kinder keine Riffe sehen, sondern nur noch Bilder davon.

Every year around Thanksgiving, I see tons of grad students post heartbreaking messages on social media about how their loved ones don’t understand or support their decision to study what seems like something pointless or silly.

Perhaps my American Scientist essay can help!

“Why Are We Funding This?”
Long-standing myths about “silly science” have contributed to the reckless slashing of government-supported research.

Seit ein paar Tagen ist es in Kraft: Ein neues Gesetz in England, das genom-editierte Pflanzen (dort: Präzisionszüchtung) ohne Fremdgene aus den #Gentechnik -Regeln herausnimmt. Freilandversuche, Anbau und Vermarktung nur noch anmeldepflichtig. Dazu Eintrag in ein öffentliches Register. #NGT
In England und vielen anderen Ländern: Kaum noch Auflagen für Pflanzen aus Präzisionszüchtung

There is a sense of awe and wonder in the writings of Darwin, Humboldt and other naturalists. A visible acknowledgment of the importance of fascination as a driver of scientific inquiry.
Today we usually shy away from the dramatic in our writing but maybe that makes science less accessible to humans
“It is interesting to contemplate a tangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other..."
#OTD in 1859 'On the Origin of Species' was published. We have a few different editions in the library @thembauk.bsky.social but we are privileged to be custodians of an early edition gifted to (a mystery) someone by Charles #Darwin himself

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.

Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.
Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

Der Tigerschnegel (Limax maximus) ist hinsichtlich der Größe (bis 13 cm) und der Tigerfärbung eine beeindruckende Erscheinung. Zur Unterscheidung von dem ähnlichen Limax cinereoniger reicht ein Blick auf die einfarbig helle Sohle.

How does messenger RNA (mRNA) get out of the nucleus to become a protein? Eukaryotic mRNA is packaged, exported, and then translated in the cytoplasm. But how do these steps work? And what are open questions? Check out our new review for our take: www.annualreviews.org/content/jour... (1/3)
