Phys.org / One-pot method synthesizes blue light-responsive aryne precursors from carboxylic acids
Arynes are highly reactive organic intermediates featuring a triple bond within an aromatic ring. Their strong reactivity enables them to form bonds with a wide range of functional groups, making them valuable tools for the ...
Phys.org / Iron core-shell catalyst boosts hydrogen economy of direct syngas to olefin conversion
Scientists have developed a new iron-based catalyst that improves the typically low hydrogen atom economy (HAE) in the direct synthesis of olefins—small hydrocarbon molecules. It converts the water produced as a by-product ...
Phys.org / Stone Age Pacific fishing practices revealed through chemical fingerprints hidden in collagen
A new collagen fingerprinting tool can help scientists identify species from archaeological bone fragments. Pacific islanders of the late Stone Age, also known as the Neolithic period, were master fishers. Archaeological ...
Phys.org / Improved iron catalysts achieve near-zero CO₂ emissions in liquid fuel synthesis from syngas
Scientists cut down over 99% of the CO2 production during the conversion of crude oil products into fuels.
Medical Xpress / Clinical trial presents promising DNA-encoded therapy for long-lasting protection against COVID-19
A new way to deliver protective antibodies against COVID-19 was tested in a Phase I clinical trial. Instead of injecting pre-made antibodies into patients, this approach encouraged the body to produce its own antibodies to ...
Medical Xpress / Rapid tooth loss linked to higher risk of death in older people
In older adults, tooth loss may be linked to serious health risks. A team of Chinese researchers analyzed data from 8,073 older participants and found that people who lost their teeth more quickly had a higher risk of dying, ...
Phys.org / New molecular strategy achieves complete synthesis of anti-MRSA natural product
Spiroaspertrione A is a complex polycyclic compound naturally produced by the fungus Aspergillus sp. TJ23. First isolated in 2017, it quickly drew scientific attention for its promising ability to combat drug-resistant bacteria ...
Medical Xpress / Gene deficiency that causes obesity also protects from heart disease, finds new study
Deficiency of the gene melanocortin 4 receptor (MC4R) is linked with obesity among adults. A recent study has found that the same deficiency also leads to surprising outcomes such as reduced risk of heart disease, lower cholesterol, ...
Medical Xpress / Social media usage linked to lower cognitive performance in preteens
Increasing social media usage among children has been linked to a decline in cognitive performance. A JAMA study involving 6,554 adolescents aged 9–13 found that those who spent more time on social media scored lower in oral ...
Phys.org / Compact laser-plasma accelerator can generate muons on demand for imaging
Muon beams can now be created in a device that is the length of a ruler.
Phys.org / Hippos survived the Ice Age in Europe, new DNA evidence reveals
Hippos from Central Europe were assumed to have gone extinct around 115,000 years ago when the temperate conditions of the region transitioned into an icy one with the end of the last interglacial period and the beginning ...
Phys.org / New study rules out binary hardening as cause of Dimorphos's orbital period drop
A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the opposite effect, given the ...
Phys.org / AI tool visually maps science funding and its real-world impacts
The impact of scientific research extends far beyond the laboratory. Breakthroughs like insulin and innovations like the internet have transformed our everyday lives. They also influence policymaking and the overall economy. ...
Tech Xplore / Thin solar-powered films purify water by killing bacteria even in low sunlight
Around 4.4 billion people worldwide still lack reliable access to safe drinking water. Newly designed, thin floating films that harness sunlight to eliminate over 99.99% of bacteria could help change that, turning contaminated ...
Phys.org / AI-generated nanomaterial images fool even experts, study shows
Black-and-white images of pom-pom–like clusters, semi-translucent fields of tiny dark gray stars on a pale background, and countless other abstract patterns are a familiar sight in scientific papers describing the shapes ...
