Genetic study separates false lingzhi from medicinal reishi species

Researchers led by the Royal Botanic Gardens, Kew have distinguished the European fungus Ganoderma lucidum from the East Asian medicinal species Ganoderma lingzhi. Using genetic material from a historic Kew specimen and comparisons with public DNA records, they found the species diverged at least 16 million years ago. The team proposes “false lingzhi” as a common name for G. lucidum and says past genetic and pharmacological attribution needs reassessment.

U.S. trial finds silver diamine fluoride arrested decay in over half of treated baby teeth

A U.S. Phase III trial of 830 children younger than 6 found that 38% silver diamine fluoride arrested decay in more than half of affected baby teeth when applied every six months. Painted onto cavities with a small sponge, the liquid avoids drilling, injections, and sedation but does not restore lost tooth material. The findings may support a future FDA application for cavity arrest, a use that remains off-label in the United States.

Cambridge team reports $10 optical sensor for compact chemical and health measurements

Researchers at the University of Cambridge and the affiliated start-up GlitterinTech have reported a miniaturized optical spectrometer designed to deliver rapid, precise measurements at an estimated $10 cost. In reported tests, it classified several foods, plastics and medicines with 100% success and measured solution concentrations at about 0.01% accuracy. Early demonstrations also measured biomarkers including glucose, but the extended glucose test involved one participant and is not evidence of clinical readiness.

Milan researchers turn soybean byproduct into a 3D-printable material for skin-repair research

Researchers in Milan made a 3D-printable blend from okara, a soybean-processing residue, and the biodegradable polymer poly(ε-caprolactone). In laboratory tests, peptides extracted from okara showed antioxidant and anti-inflammatory activity and promoted migration of human dermal fibroblasts. The printed material retained those properties and released peptides over time, supporting further preclinical investigation for wound-care applications.

Japan launches mission to return samples from Mars moon Phobos

Japan has launched an uncrewed, five-year mission to collect samples from Phobos, one of Mars’s two moons, and return them to Earth by 2031. Al Jazeera reports that, if it succeeds, it would be the first mission to return samples from a moon of Mars. No samples have yet been returned and no scientific findings are reported.

Anthropic plans to place 5% of its shares in public-benefit fund

Anthropic says it will commit 5% of its shares to a Public Benefit Fund intended to support donations for the public good. The company says the fund could back nonprofit organisations and work addressing AI’s effects on jobs, while its shares would not be used for lobbying or political donations. Anthropic says its board may allocate a further 2% of shares to the fund.

Animal study links gut repair to reversal of severe fatty liver disease

Researchers report that the experimental tripeptide DT-109 reversed metabolic dysfunction-associated steatohepatitis (MASH) in mouse and nonhuman-primate models. The compound reduced Clostridium perfringens, lowered intestinal ammonia, reinforced the gut barrier and was associated with less liver inflammation and MASH severity. The findings have not yet established safety or effectiveness in people.

Small viruses point to two-way evolution between viral shells and cellular compartments

University of Miami researchers report identifying previously unknown viruses with HK97-fold protein shells that share features with both viruses and encapsulins, cellular protein compartments. Their analysis supports repeated evolutionary transitions between the two, rather than a one-way origin of encapsulins from viruses. The work was published in Nature Communications.

Vienna team turns aromatic plastic waste into air-water adsorbents

University of Vienna materials chemists report converting aromatic plastic waste into porous, sulfonated polymer networks that draw moisture from air and release it under mild heating. Feedstocks included polystyrene packaging, polycarbonate CDs, acrylonitrile butadiene styrene LEGO bricks, and a selected mixed-plastic feedstock. In one polystyrene example, the material adsorbed nearly 60% of its own weight in humid air and 20% in dry, desert-like conditions.

AI-expanded model maps overlooked reactions in CO2 hydrogenation

Researchers at the Indian Institute of Science combined quantum-mechanics simulations, machine learning and automated reaction discovery to expand a copper-catalyst CO2-hydrogenation network from 152 to 9,389 reactions. The larger model aligned with experimental product observations, estimated about 40 times more CO2 conversion than the limited model, and identified a possible direct molecular-hydrogen transfer route.

New global estimates map a largely unrecorded burden of snake envenoming

An analysis of evidence from 79 countries and a geostatistical model estimates that at least 2.1 million people experience snake envenoming each year, with the total potentially reaching 7 million. Modeled annual deaths range from 274,000 to 513,000, and sub-Saharan Africa accounts for an estimated 45% of envenomings and deaths. The country-level risk maps are intended to help target antivenom, trained health workers and transport support.

Injectable, wire-free nerve-stimulation device shows early preclinical results

Researchers at NYU Abu Dhabi and Cleveland Clinic Abu Dhabi developed a seed-sized device that can be injected near a peripheral nerve and powered wirelessly outside the body. Laboratory and preclinical tests showed it could provide programmable stimulation and activate nerves in vivo. The study does not establish that the device relieves chronic pain or improves movement disorders in people.
