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.
Metformin Cuts Insulin Use 12% in Type 1 Diabetes Trial
A Garvan Institute clinical trial found that metformin, a century-old Type 2 diabetes drug, reduced insulin requirements by about 12% in Type 1 diabetes patients—despite failing to improve the insulin
Study: 2 Common IBS Drug Classes Linked to Higher Death Risk
A 20-year study of over 650,000 IBS patients found that long-term use of antidepressants and opioid-based antidiarrheals like loperamide was associated with significantly higher mortality risk, though
Bacteria Repurpose Anti-Virus Defenses to Spread Resistance
John Innes Centre researchers discovered that bacteria repurpose an anti-phage immune system called LypABC to control the release of gene transfer agents—virus-like particles that spread DNA, includin
UCD Discovers Cell Courier for Gene Therapy
Researchers at University College Dublin have discovered a natural 'courier system' in cells that can deliver functional biomolecules between cells, opening new pathways for RNA and gene therapies by
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

Anti-Amyloid Alzheimer's Drugs Show 'Trivial' Effect: Review
A Cochrane review of 17 clinical trials covering more than 20,000 people concluded that anti-amyloid Alzheimer's drugs produce a 'trivial' effect on cognition and dementia severity over 18 months, und
Voronoi Method Exposes Flaws in Crowd Flow Measurement
A study published in the Journal of Statistical Mechanics: Theory and Experiment finds that traditional crowd flow measurement methods—borrowed from fluid dynamics—produce inconsistent and sometimes m
Leipzig team finds hidden π–π switch in BAI2 receptor
Leipzig University researchers identified a hidden π–π amino acid switch that controls self-cleavage in adhesion GPCRs, explaining why the BAI2 receptor takes roughly 100 days to activate and opening
RMIT color test spots deadly staph strains fast
RMIT University researchers have created a rapid color-changing test that distinguishes dangerous golden staph strains from less harmful ones, using gold nanoparticles and DNA binders to generate colo
780,000-Year-Old Charcoal Reveals Early Humans Used Lake Driftwood
A new study analyzing 266 ancient charcoal fragments from the 780,000-year-old Acheulian site of Gesher Benot Ya'aqov in northern Israel reveals that early humans relied primarily on naturally accumul
Guano Mercury Reveals 8,000 Years of Seabird History
Researchers have used mercury preserved in 8,000-year-old seabird guano deposited in peat to reconstruct population dynamics on a sub-Antarctic island, finding that colony sizes closely tracked Southe
Hawaii Songbirds Steal Nest Materials From Each Other
Hawaiian songbirds are stealing nest-building materials from one another at high rates, and UC Riverside researchers tracking more than 200 nests found the behavior adds measurable pressure to native
Largest universe map ever: 47M galaxies cataloged
The Dark Energy Spectroscopic Instrument (DESI) has completed its main five-year survey, cataloging 47 million galaxies and quasars — nearly 10 times more objects than all previous cosmic maps combine
University of Toronto Study Links Mental Sharpness to 40‑Minute Productivity Gains
A University of Toronto Scarborough study shows that daily fluctuations in mental sharpness can add up to 40 minutes of productive work, but sustained overwork eventually erodes this advantage signifi
Artemis II breaks distance record on Moon far side flyby
NASA's Artemis II crew broke the 56-year-old human spaceflight distance record held by Apollo 13 during a dramatic lunar far side flyby, becoming the first humans to directly view parts of the Moon's
