This unassuming little lumpkin is the world’s oldest surviving tool, excavated from the archaeological site of Lomekwi 3 in Kenya. It was made some 3.3 million years ago by a human ancestor, probably someone like afarensis or Kenyanthropus (images 2-3).

This year's #NobelPrize in Chemistry will be awarded tomorrow 🏅 Here's a reminder of the research that has won in previous years, including molecular sponges, the prediction of protein structures, and clicking together new medicine molecules: www.compoundchem.com/category/nob... #ChemSky 🧪
Infographic titled "2022 Nobel Prize in Chemistry" celebrating Carolyn R. Bertozzi, Morten Meldal, and K. Barry Sharpless for click and bioorthogonal chemistry. Sharpless coined "click chemistry" in 2001 for quick, selective reactions without unwanted byproducts. Sharpless and Meldal independently developed the first reaction using a copper catalyst to combine azides and alkynes. Bertozzi developed copper-free click chemistry in 2003 for live cell applications like tracking glycans. Applications include drug synthesis and targeting cancer.Infographic titled "The 2023 Nobel Prize in Chemistry" honoring Moungi G. Bawendi, Louis E. Brus, and Alexei I. Ekimov for discovering and synthesizing quantum dots. Quantum dots are semiconductor nanoparticles whose light absorption and emission change with particle size due to quantum effects. In 1981, Ekimov created size-dependent color in tinted glass; in 1983, Brus discovered size-dependent absorption/emission in liquid solutions; in 1993, Bawendi developed a precise synthesis method. Applications include QLED TVs, LED lamps, flexible electronics, and solar cells.Infographic titled "The 2024 Nobel Prize in Chemistry" honoring David Baker for computational protein design, and Demis Hassabis and John M. Jumper for protein structure prediction. Proteins fold into 3D structures determining their function. In 2020, Hassabis and Jumper introduced AlphaFold2, an AI model that evaluates amino acid interactions to predict 3D folded structures, now used on nearly 200 million proteins. David Baker created Rosetta software to work in reverse, designing amino acid sequences for custom protein structures, succeeding in 2003. Applications include protein-based drugs, vaccines, and catalysts.Infographic titled "The 2025 Nobel Prize in Chemistry" honoring Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for the development of metal-organic frameworks (MOFs). MOFs are porous molecular sponges composed of metal ions connected by organic linkers, allowing small gas molecules to move in and out of their cavities. In 1989, Robson combined copper ions with four-armed molecules. In 1997, Kitagawa created stable and flexible gas-storing MOFs using cobalt ions. In 1999, Yaghi built MOF-5 with zinc clusters, achieving massive internal surface area. Applications include gas storage, harvesting water from air, targeted drug delivery, and toxic chemical detection.

How rare are neutrino interactions? A neutrino (of the type emitted by the Sun) could go through a light year of lead with only a small chance of interacting. They pass through the Earth, and each of us, constantly, without anyone noticing. 100 trillion neutrinos go through you every second.

I attended a seminar by freshly minted Nobel Laureate Francis Halzen many years ago and something he said stuck with me, but it takes some explaining, so this will be a (short) thread. The talk was about neutrino telescopes, and he started by explaining how rarely neutrinos interact with anything.

11. I will not be taking questions.The story of a woman whose data was stolen by two ambitious men who then did not credit her seems to be too powerful to be overcome by mere facts. This is, of course, all Watson's fault because of how he presented events. We are all hoist by his petard.

8. The discovery was not the sole work of Watson and Crick, nor was it seen as such at the time. All three groups published back to back in Nature under a common title, and the reprints were bound together. The first public presentation of the double helix took place in June. Look at the authors:

(this was not clear until after the double helix; experimental proof was initially slight and limited to microbes for over two decades). 5. It still needs saying: Franklin did NOT discover the double helix; no historian says she did. She did not twig that there was complementary base pairing
