Welsh Rivers Contaminated by Pet Flea Pesticides
A joint Cardiff University and Natural Resources Wales study found that veterinary pesticides from pet flea treatments and sheep dips are widespread in Welsh rivers, with many samples exceeding safe l
Paternal Nicotine Exposure Alters Mouse Metabolism
A mouse study shows that nicotine exposure in fathers can cause metabolic alterations in their offspring, including lower insulin and glucose levels and liver dysfunction, implying a heightened risk o
Melatonin in kids: review flags evidence gaps, poisonings
A major review warns that melatonin use among children has surged far ahead of the scientific evidence supporting its safety and effectiveness, especially in typically developing kids.
Rice price surge linked to child stunting and obesity
A University of Bonn study finds that the late‑1990s rice price inflation during Indonesia’s Asian financial crisis caused lasting growth deficits in children and heightened obesity risk in adulthood,
TDP43 Controls DNA Mismatch Repair, Ties ALS & Cancer
Researchers discovered that TDP43, a protein known for ALS and dementia, also regulates DNA mismatch repair, linking neurodegeneration to cancer and pointing to potential treatment strategies that mod
Durham finds stable proteins that boost LAMP speed
Durham University led a team that uncovered DNA‑binding proteins from Icelandic volcanic lakes and North Atlantic vents, whose thermal and chemical stability boosted speed and sensitivity of LAMP test
Study Finds Lithium Dendrites Are Strong, Brittle
A new Science study directly measured the nanomechanical properties of lithium dendrites inside operating batteries, revealing they are surprisingly strong and brittle, a discovery that clarifies how
Crocodiles Show 5‑6 Cycles Yearly, Doubt Dinosaur Ages
Scientists discovered that juvenile crocodiles can produce five to six bone growth cycles annually, meaning skeletochronology may overestimate ages and casting doubt on dinosaur age reconstructions ba
Peroxiredoxins Form Mixed Oligomers, Not Just Rings
Researchers have overturned a decades-old assumption that peroxiredoxins — among the cell's most abundant antioxidant enzymes — assemble exclusively into identical 10-subunit rings, showing the enzyme
Cambridge team turns plastic into vinegar with sunlight
Researchers at Cambridge have devised a sunlight‑driven, iron‑based catalyst that converts common plastic waste directly into acetic acid at room temperature and atmospheric pressure, offering a mild,
Yaku'amide B Degrades CD9 and Inhibits ATP Synthase in Cancer Cells
Researchers reveal that deep‑sea natural product yaku'amide B kills cancer cells by simultaneously degrading the stem‑cell marker CD9 and blocking mitochondrial ATP synthase, explaining its potent ant
Eaton fire emitted CO at 20× LA’s daily human emissions
A USC study finds the 2025 Eaton wildfire emitted carbon monoxide at over 20 times Los Angeles County's daily human‑caused emissions, releasing 153 million kg of carbon and driving PM2.5 levels above
Next-gen iDWS boosts cerebral blood flow signal 20x
A new interferometric diffusing wave spectroscopy (iDWS) technique amplifies the optical signal for cerebral blood‑flow monitoring by 20‑fold, delivering deeper, faster, non‑invasive readings. The bre
JWST Detects CO2 Ice in Butterfly Nebula, Volatile Ice
Astronomers using JWST have identified carbon‑dioxide ice in the dusty torus of the Butterfly Nebula, marking the first detection of a volatile ice species in a planetary nebula.
Michigan study: eye cell death reversible via mitophagy
A University of Michigan study shows that dying photoreceptor cells can reverse apoptosis when stress is removed, with functional mitochondria and mitophagy enabling recovery, offering new therapeutic
NMR Reveals Antibody Structure Without Isotope Labeling
Researchers developed an NMR-based method that detects site-specific structural signatures in therapeutic antibodies without requiring isotope labeling, enabling residue-level analysis of the IgG1 Fc
Neurology of boring sounds; one huge croc; Travels
Researchers pinpointed the orbitofrontal cortex as the brain’s "noise‑canceller," a breakthrough that could soon tame sensory overload and boost brain‑computer interfaces; at the same time, decoding m
Waveguide Boosts Real‑Time Protein Folding Observation
A new fluorescence microscopy technique using a nanophotonic waveguide lets researchers watch protein folding unfold in microseconds, revealing that larger proteins fold through coordinated, simultane
Hair Grows by Being Pulled, Not Pushed: Study
Human hair grows by being pulled upward by moving cells inside the follicle, not pushed out from the root as biology textbooks have long claimed, according to new 3D imaging research that could reshap
China's quantum dot yields 98.3% entangled photon pairs
Researchers at the Beijing Academy of Quantum Information Sciences have engineered quantum dots to emit entangled photon pairs on demand with a 98.3% pair‑generation efficiency, a breakthrough that co
