Traditional Chinese Medicine Has Not Been Vindicated by Science

People love to show that skeptics were wrong about something, especially when national pride hangs in the balance. The South China Morning Post published the following headline on November 3rd: “Scientists find traditional Chinese medicine is based on a complex network of proteins – 3,000 years before modern science.” The article points out that respectable editorials in the scientific literature had repeatedly referred to traditional Chinese medicine (TCM) as “largely just pseudoscience” and “

We’ve had a Denisovan skull since the 1930s—only nobody knew

news.ycombinator.com Unknown 2025-08-31 04:42:58

A 146,000-year-old skull from Harbin, China, belongs to a Denisovan, according to a recent study of proteins preserved inside the ancient bone. The paleoanthropologists who studied the Harbin skull in 2021 declared it a new (to us) species, Homo longi. But the Harbin skull still contains enough of its original proteins to tell a different story: A few of them matched specific proteins from Denisovan bones and teeth, as encoded in Denisovan DNA. So Homo longi was a Denisovan all along, and thank

Toxic Proteins for Drug Discovery

news.ycombinator.com Asimov Press 2025-09-06 19:04:22

Noah Whiteman, professor of evolutionary biology at UC Berkeley, writes about how toxins are repurposed into medicines for Issue 06. Whiteman’s recent book is called “Most Delicious Poison.” Ella Watkins-Dulaney for Asimov Press. When you hear the word "poison," perhaps you picture a Victorian-era cobalt bottle labeled "NOT TO BE TAKEN" or the iconic pictogram of a leering skull and crossbones. What probably does not come to mind, however, are the dried white beans in your kitchen pantry, the

This company is trying to make a biodegradable alternative to spandex

“True circularity has to start with raw materials,” says Peña. “We talk about circularity across many industries, but for textiles, we must address what we’re using at the source.” Engineered from recombinant DNA, SELPs are copycat proteins inspired by silk and elastin that can be customized for qualities like tensile strength, dye affinity, and elasticity. Silk’s amino acid sequences—like glycine-alanine and glycine-serine—give fibers strength, while elastin’s molecular structure adds stretchi
