Researchers have extracted living yeast from the gut of Ötzi the Iceman, a 5,300-year-old frozen mummy discovered in the Alps, and successfully used it to bake sourdough bread. The find offers a rare window into prehistoric fermentation and the microbiome of ancient humans. It also raises the remarkable possibility that strains of yeast in use today share a direct lineage with those consumed in the Copper Age.
Read article →Researchers have developed two precision control systems—PRINCE and Little Prince—that allow CRISPR gene editing to be activated on demand using small-molecule drug compounds, while remaining largely inactive otherwise. The breakthrough addresses one of therapeutic CRISPR's most persistent challenges: preventing off-target edits that occur when the system runs unchecked in living tissue. The ability to dial gene editing activity up or down with a drug could significantly improve the safety profile of CRISPR-based treatments moving toward clinical use.
Read article →Greenland's melting ice sheet is contributing to the slowdown of the Atlantic Meridional Overturning Circulation, the vast ocean current system that regulates climate across the Northern Hemisphere. A updated model incorporating Greenland meltwater finds the AMOC is under greater stress than previously understood, but stops short of predicting a catastrophic collapse. The findings offer measured reassurance while reinforcing the urgency of limiting ice loss before conditions shift further.
Read article →Coastal flooding events that were once rare occurrences are now 12 times more likely, driven by human-caused climate change pushing sea levels higher. The findings, published Wednesday, underscore the accelerating risk facing coastal communities worldwide. Experts say the research should reshape how governments and planners approach flood preparedness and infrastructure investment.
Read article →Antibiotic resistance is on track to become one of the deadliest crises of the century, with projections pointing to over 8 million annual deaths by 2050. Researchers are now turning to generative AI combined with physics-based modeling to accelerate the discovery of new antibiotic compounds. The approach could dramatically cut the time and cost of drug development at a moment when the pipeline for new antibiotics has run dangerously dry.
