Climate change slows Earth’s spin: Day lengthening unprecedented in million years

Climate change is lengthening our days because rising sea levels slow Earth’s rotation. Researchers from the University of Vienna and ETH Zurich now show that the current increase in day length – 1.33 milliseconds per century – is unprecedented in the past 3.6 million years. The team reconstructed ancient day-length fluctuations using the fossil remains of single-celled marine organisms known as benthic foraminifera.

Why averages fail for bacteria in the open ocean

Why averages fail for bacteria in the open ocean

How can bacteria that forage on organic particles survive in vast ocean regions where such particles are extremely sparse? A new study by researchers from ETH Zurich and Queen Mary University of London shows that variability at the level of individual bacteria plays a central role. Using a probabilistic population model linking mathematics and microbiology, the team demonstrates that rare, high-impact encounters sustain bacterial populations even when average conditions suggest decline.
