Decorrelation Stretch, a NASA Imaging Trick, Uncovers Hidden Angkor Wat Paintings

A NASA-developed image-processing method called decorrelation stretch, originally created to pull extra detail from satellite and Mars rover photos, has been repurposed to reveal ancient artwork invisible to the naked eye. Using this technique, a Singaporean archaeologist uncovered roughly 200 faded paintings at Angkor Wat between 2010 and 2012, including scenes of horseback riders and musicians. The method reached archaeology through Jon Harman, a medical imaging professional and rock-art hobbyist who adapted NASA's published algorithm into the widely used Dstretch software.

Ancient proteins confirm Denisovan teeth found in Yunnan's Bianfu Cave

Researchers analyzed proteins from two fossilized teeth—a fourth premolar and a second molar—recovered from Bianfu Cave in southwestern China's Yunnan Province, dated to roughly 140,000 years ago. The proteomic evidence confirms these remains belong to Denisovans, adding to the small but growing collection of physical evidence for this elusive archaic human population. The cave, one of the oldest Palaeolithic sites in western Yunnan, also yielded thousands of stone tools and animal fossils alongside four hominin teeth.

Ancient protein analysis identifies new Denisovan fossils in Southwest China

Researchers used ancient protein analysis to identify additional Denisovan skeletal remains from a site in Southwest China, expanding the known geographic and fossil record of this archaic human population. The study, published in Nature, builds on prior genetic and proteomic work that has traced Denisovans from Siberia's Denisova Cave to the Tibetan Plateau, Laos, Taiwan, and now southwestern China.

Mexico City cohort study links genetic ancestry variation within families to health traits

Researchers analyzed genome-wide data from over 140,000 participants in the Mexico City Prospective Study, combining it with reference panels from the 1000 Genomes Project and Human Genome Diversity Project to estimate individual ancestry proportions across Indigenous American, European, African and East Asian populations. Using an ADMIXTURE model with four ancestral groups, they examined how differences in ancestry proportions among siblings within the same family relate to complex traits, isolating genetic ancestry effects from shared environmental and socioeconomic factors.

Razer BlackShark V3 Pro gaming headset discounted to $164.99 at Woot

Woot is selling the Razer BlackShark V3 Pro headset for $164.99, nearly $100 off its usual price.

Essay on non-fiction writing advises starting from the 'trunk' before branches

A personal essay recounts a university mishap where a professor accused a student of being carried by a group partner on an Ancient History project, despite the student having written the bulk of the work himself. The writer uses this anecdote to introduce a broader lesson on non-fiction writing: establish the central idea, or 'trunk,' before adding supporting details, or 'branches.'
