An analysis of more than two decades of U.S. health data found that blood bicarbonate levels rose about 7% since 1999, while calcium and phosphorus levels declined. The pattern tracks the increase in atmospheric carbon dioxide.

A large new analysis challenges the long-standing idea that a distinctive genetic system drove the evolution of complex societies in ants, bees, and wasps. It concludes that genetics alone cannot explain their social behavior and points instead to other traits shared by these insects.

Europe's scorched landscapes seen from space after summer heatwaves
Summary
Satellite imagery shows how drought and extreme heat have altered western Europe's rivers, farmland and mountain landscapes. The evidence captures the physical effects of a summer of severe heatwaves across the region.
The damage extends beyond high temperatures: depleted rivers, stressed crops and changed mountain conditions put

Scientists detect a surprising shift in human blood as atmospheric CO2 rises
Summary
An analysis of more than two decades of U.S. health data found that blood bicarbonate levels rose about 7% since 1999, while calcium and phosphorus levels declined. The pattern tracks the increase in atmospheric carbon dioxide.
The key shift is evidence that rising environmental CO2 may be associated with measurable changes

A 60-year-old theory about ants, bees and wasps may be wrong
Summary
A large new analysis challenges the long-standing idea that a distinctive genetic system drove the evolution of complex societies in ants, bees, and wasps. It concludes that genetics alone cannot explain their social behavior and points instead to other traits shared by these insects.
The central shift is from a single genetic explanation to a broader account of social

Researchers found that gut microbes deprived of dietary fiber can consume proteins in the mucus lining that protects the intestine. Fiber suppressed this behavior, while indigestible plant proteins encouraged microbes to produce more beneficial compounds.

Researchers reexamined fossils collected in Osaka more than 30 years ago and identified four previously overlooked bones from a giant Cretaceous mosasaur. The set includes the first confirmed mosasaur premaxilla found in Japan, while unusual skull features may indicate an unknown species.

When gut microbes run low on fiber, they may start eating you
Summary
Researchers found that gut microbes deprived of dietary fiber can consume proteins in the mucus lining that protects the intestine. Fiber suppressed this behavior, while indigestible plant proteins encouraged microbes to produce more beneficial compounds.
The decisive finding is that low fiber can push microbes to weaken the gut's protective

Summary
Researchers reexamined fossils collected in Osaka more than 30 years ago and identified four previously overlooked bones from a giant Cretaceous mosasaur. The set includes the first confirmed mosasaur premaxilla found in Japan, while unusual skull features may indicate an unknown species.
