ThermoCas9 Cuts Tumor DNA While Sparing Healthy Cells
Scientists have engineered a CRISPR enzyme, ThermoCas9, that reads DNA methylation patterns to selectively cleave tumor DNA while leaving healthy DNA untouched, marking a novel approach to precision c
UQ creates light-activated oxytocin switch
University of Queensland researchers have developed a molecular 'light switch' for oxytocin and vasopressin that releases the neuropeptides on demand at specific brain locations, enabling precise stud
Surrey, King's trace cancer drug uptake in living cells
Researchers from the University of Surrey and King's College London have developed a method to detect trace metals inside individual living cells, letting scientists track where cancer drugs accumulat
Agulhas Current Eddies Drive Coastal Climate Extremes
A new study in Nature Climate Change shows intensifying ocean eddies in the Agulhas Current are warming surface waters up to four times the global average while simultaneously cooling deeper waters th
QUT Team Turns AI Proteins Into Molecular Sensors
An international team led by QUT researchers has shown that AI-designed proteins can function as molecular switches that activate when they detect a specific target, challenging a long-held assumption
Fred Hutch Antibody Fully Blocks EBV in Mice
Fred Hutch scientists engineered human-like antibodies in transgenic mice that fully blocked Epstein-Barr virus from infecting immune cells in lab models, opening a potential path to preventing post-t
Allopurinol Cuts Heart Attack, Stroke Risk in Gout
A University of Nottingham study of nearly 110,000 gout patients found that lowering serum urate to below 360 µmol/L with allopurinol reduces five‑year heart attack, stroke, and cardiovascular death r
Neanderthal Origins: Three Ancestor Candidates, No Answers
Despite rich fossil finds and genetic sequencing, Neanderthals' evolutionary origins remain unsolved, with three candidate ancestors — Homo erectus, Homo antecessor, and Homo heidelbergensis — each fa
Micro-CT Scans Don't Damage Ancient DNA, Bonn Study Finds
University of Bonn researchers found that micro-CT scanning does not statistically damage ancient DNA in petrous bone samples, paving the way for a non-destructive workflow that digitally preserves ir
Rice Simulations Secured Orion Parachutes
A Rice University computational analysis of fluid‑structure interaction was pivotal in stabilizing Orion’s three‑parachute system, enabling the safe Pacific splashdown of the Artemis II crew on April
Drone flies match honey bees pollinating berries
Researchers at the University of New England demonstrated that the drone fly (Eristalis tenax) can pollinate blackberry and raspberry crops as effectively as managed honey bees, even outperforming the
RESF1 gene linked to Addison's disease in dogs
Researchers have identified a gene variant, RESF1, strongly associated with Addison's disease in Nova Scotia duck tolling retrievers, and the gene's similarity across species points to it as a candida
Chandra Finds Young Sun-Like Stars Dim 15x Faster Than Predicted
A NASA Chandra X-ray Observatory study of eight star clusters finds young sun-like stars dim their X-ray output roughly 15 times faster than predicted, potentially preserving the atmospheres of orbiti
Large‑egg‑laying Japanese quails live 20% shorter
A University of Exeter study shows that Japanese quails bred to lay larger eggs age faster and die about 20% earlier, confirming a key evolutionary trade‑off between reproductive investment and lifesp
Akbari's formula converts albedo to CO₂ offsets
Professor Hashem Akbari unveiled a streamlined, weather‑data‑driven formula that translates surface albedo changes into CO₂‑equivalent offsets, enabling regional climate accounting for cool roofs and
Alena Tensor Models Dark Matter No Invisible Particles
A new mathematical framework called Alena Tensor, detailed in a Physica Scripta paper, unifies curved and flat spacetime, classical and quantum descriptions, and can mimic dark‑matter‑like gravitation
SwRI AI Generates Sunspots to Find Rare Solar Matches
Southwest Research Institute scientists have built a three-part AI system that generates virtual sunspot-like magnetic patches and uses them as search queries against decades of real solar observation
Physicist: Mozi Predated Newton's First Law by a Millennium
A physicist watching Project Hail Mary in IMAX was struck by the film's accurate physics and connected the experience to a realization that Mozi's followers wrote down something like Newton's first la
Scattered insects boost poultry welfare, study shows
Researchers have found that scattering live insects in broiler chicken houses stimulates natural foraging and activity, reducing health issues tied to intensive breeding. The low‑cost enrichment, demo
Blocking Ant2 Protein Supercharges T Cells Against Cancer
Researchers at Hebrew University found that blocking the Ant2 protein rewires T cell energy production, dramatically boosting their ability to find and destroy cancer cells in mice.
