The permanent rise of oxygen in the Earth’s atmosphere, which fundamentally changed the subsequent nature of Earth’s habitability, occurred much later than thought, according to new research. And the study, from an international team led by the University of Leeds and including researchers from the University of California-Riverside, Harvard University, […]

The new species was discovered in the dunes on Lista in Farsund municipality. Credit: Arnstein Staverløkk, NINA, CC BY3.0 A brand new species of parasitic cuckoo wasp was discovered based on its clever use of pheromones. Cuckoo wasps – also called emerald wasps – are some of the most beautiful […]

An artist’s impression of a “string” passing near a black hole. As the string approaches the black hole, it is gradually stretched. Then, as it moves past the black hole, it begins to vibrate. The image to the left, which was captured by the Event Horizon Telescope, represents the shadow […]

Atlantic cod was once one of the most important fish species in the world. The big, long-lived predator helped feed Europe and North America for centuries. But decades of overfishing in the mid–20th century caused populations to crash, wiping out 30,000 jobs in Canada alone and financially devastating many coastal […]

A typical endurance horse (Arabian breed) presented for a gait test before the start of the race to check locomotor soundness. During an endurance competition (100-160 km), horses must undergo veterinary inspection at the end of each 20 to 40 km loop to check their recovery and capacity to continue […]

Nacre, or mother-of-pearl, found in red abalone and other mollusks, is extremely fracture-resistant. That’s one reason researchers are interested in the natural material, and why UW–Madison scientists wanted to find a method to measure its thickness without harming the nacre.
