Sparkling Water Gives Small Metabolic Boost, Study Finds
A BMJ Nutrition Prevention & Health analysis finds that drinking sparkling water may modestly boost glucose uptake and metabolism, but the effect is too small to serve as a weight‑loss solution.
Brazilian Team Supercharges CAR-NK Cells Against Tumors
Researchers in Brazil engineered CAR-NK cells with 2B4 and DAP12 costimulatory components, significantly boosting their ability to destroy tumor cells. Combining these activation signals with temporar
Preconception X-ray alters offspring mtDNA in mice
Hokkaido University researchers report that X-ray exposure in mice before conception reduced mitochondrial DNA copy numbers in the brains and livers of their offspring, with the effect depending on wh
Agrovoltaic tomato system halves water, trades 20% yield
Two Spanish universities showed that growing tomatoes under solar panels with reduced irrigation is more land-efficient than farming and energy production on separate plots, cutting water use by about
Methylsiloxanes Found in Air at 1000x PFAS Levels
A new study reveals that large molecular methylsiloxanes, a previously overlooked class of synthetic pollutants, are widespread in the atmosphere at unexpectedly high levels, raising concerns about hu
JWST Little Red Dots Back Heavy-Seed Black Holes
Astronomers using JWST data on mysterious Little Red Dots find that the 'heavy seed' model of black hole formation—direct collapse of primordial gas clouds—better explains these early-universe superma
Brodeur Study Finds 85% Social Papers Reproducible
A new Nature study led by Abel Brodeur finds that 85% of recent social‑science papers are computationally reproducible, suggesting that open‑science practices have strengthened research reliability si
Mass‑spectrometry reads 2 M Antarctic dust grains
A new mass‑spectrometry technique lets scientists examine over two million individual dust particles from Antarctic ice, uncovering a shared source of dust during the last Ice Age and detailing shifts
Bar-Ilan Runs 23 Quantum Channels on One Light Beam
Bar-Ilan University researchers demonstrated that a single beam of light can carry 23 simultaneous secure quantum channels, using ultrafast detection to break the measurement bottleneck that has limit
Laser pulses show rugby‑ball shape of neptunium fermium
Researchers at the University of Gothenburg have developed a laser‑pulse technique that can probe the decay of radioactive nuclei in seconds. Their thesis shows that the heavy elements neptunium and f
Xa48 gene discovery enables disease-resistant rice breeding
Scientists in China have cloned a new broad-spectrum bacterial blight resistance gene, Xa48, revealing how it balances immunity and yield in rice and enabling more resilient crop breeding.
Salford to Shanghai: Cities Take Back Housing
A new University of Manchester study published in Urban Studies finds that governments in six cities—from Salford to Shanghai—are abandoning light-touch housing policy in favor of active, experimental
Negritos Preserved Smell Genes for Rainforest Foraging
A Cell Reports study of Malaysia's Orang Asli people found that hunter-gatherer Negritos preserved more functional olfactory receptor genes than other populations, suggesting human smell evolved along
AIMS Launches Coral Reef Intervention Risk Database
AIMS unveiled a database helping scientists and reef managers evaluate ecological risks of coral reef interventions, from coral gardening to assisted evolution, with findings showing risks vary sharpl
Single Cohesin Motors Form 60-70% of DNA Loops
Researchers from Skoltech and the University of Potsdam used polymer physics to show that single cohesin motors — not teams of them — extrude the DNA loops that compact 60-70% of cellular DNA, with lo
Waikīkī Floods Will Turn Tidal and Sewage-Contaminated
University of Hawai'i at Mānoa researchers published a study finding that Waikīkī's flood hazards are shifting from rainfall-driven events to tidal-driven flooding contaminated with sewage, pathogens,
UCLA clears zombie immune cells, reverses liver damage
UCLA researchers found 'zombie' senescent immune cells accumulate to 60-80% of liver macrophages in older mice, and removing them reversed fatty liver damage even on a high-fat diet.
Feedstock Leak Could Delay Ozone Recovery by 7 Years
A new MIT‑led study shows that higher-than‑expected leakage of ozone‑depleting chemicals used as industrial feedstocks could postpone the stratospheric ozone layer’s recovery by about seven years, hig
Researchers map 232 elephant genomes, find isolation
A continent‑wide genomic survey of 232 African elephants shows historic continental connectivity but now widespread genetic isolation, especially in remote north‑eastern populations, prompting urgent
EU Cut Emissions 86% by 2040 Scale Renewables Seven‑Fold
A new PIK study shows the EU can meet its 2050 net‑zero goal by 2040 with an 86% emissions cut, massive renewable expansion, and rapid CO₂ removal, while slashing fossil‑fuel imports.
