Ich glaube ich fahre zum nächsten Oktoberfest, einfach nur um neben Markus Söder zu stehen, wenn er einem Grünen zuschaut, wie er das Fest eröffnet.

Despite his teacher’s opinion that he couldn’t learn simple biology, John Gurdon went on to receive a #NobelPrize, for his classic frog experiment, which showed that the DNA of mature frog cells has all the information needed to develop all cells in its body.

In vitro reconstitution is powerful: we rebuild Plasmodium microtubule architectures from purified components & recapitulate what cells actually do🤩
Thanks to the team that made this possible🙌 in particular Carolyn Moores @BirkbeckScience

One of the most important discoveries in molecular biology, I'd say, happened in 1974 when scientists took a gene from a frog (Xenopus laevis) and transferred it into a bacterium (E. coli). The bacterial cells read, processed, and expressed the gene.
If a bacterium can read a frog gene, so the logic went, then the entire living world is, in principle, "programmable." Genes can be swapped between kingdoms of life, thus enabling:
- The production of human insulin in bacteria.
- Manufacturing of vaccines in yeast and chicken eggs
- Engineered crops carrying biopesticide genes from algae etc.
Check out A Brief History of Xenopus to learn about other key experiments in which frogs played a role. 🔻

In the 1930s, South African scientists discovered that injecting African Clawed Frogs (called Xenopus laevis) with urine from a pregnant woman would cause them to quickly lay hundreds of eggs.
These frogs thus served as the first mass-scale pregnancy test.
Xenopus frogs later became the first animals cloned from an adult cell (three decades before Dolly the Sheep). This is A Brief History of Xenopus, an essay adapted from our forthcoming book about the origins and future of the research laboratory.

Statement from the Nobel Foundation
One of the core missions of the Nobel Foundation is to safeguard the dignity of the Nobel Prizes and their administration. The Foundation upholds Alfred Nobel’s will and its stipulations. It states that the prizes shall be awarded to those who "have conferred the greatest benefit to humankind," and it specifies who has the right to award each respective prize. A prize can therefore not, even symbolically, be passed on or further distributed.
For additional information, please refer to the Norwegian Nobel Committee: nobelpeaceprize.org/press/pr…

David Bowie picked Annie Lennox to perform Under Pressure with him at the '92 Freddie Mercury Tribute Concert. This rehearsal is AMAZING. Bowie’s expression alone is PRICELESS. What other famous artist can you spot?
