What happens to high mountain ecosystems when you take away air pollution? Not much, not very quickly. A new CU research study finds that degraded alpine ecosystems showed limited recovery years after long-term inputs of human-caused nitrogen air...

Compared with the rest of the animal kingdom, mammals have the biggest brains and produce some of the smallest litters of offspring. A newly described fossil of an extinct mammal relative -- and her 38 babies -- is...

An avalanche is an extremely complex event, with countless parameters and physical variables coming into play from the time the avalanche is triggered until it ends. Johan Gaume, a researcher in the Laboratory of Cryospheric Sciences (CRYOS) and...

New, higher-quality assemblies of great ape genomes have now been generated without the guidance of the human reference genome. The effort to reduce "humanizing" discovery bias in great ape genomes provides a clearer view of the genetic differences...

Of the known alien (non-native) species found in Antarctica, a non-biting species of midge currently presents one of the highest risks to terrestrial ecosystems, researchers have found. Eretmoptera murphyi is a flightless midge, which is thought to have been...

Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes. Instead, gas expelled from the center...

Chimpanzees have a more elaborate and diversified material culture than any other nonhuman primate. Their behavior varies across tropical Africa in a way that does not always correspond to ecology: for instance, only West African chimpanzees, but no...

A study from the Faculty of Biology and the Biodiversity Research Institute of the University of Barcelona (IRBio-UB) analysed how water macroinvertebrate species, such as beetles, mosquitos and dragonflies, evolved and diversified since their beginnings. With the analysis...

Worker ants, despite their diligence, seldom encounter opportunities for social mobility. In many species, individuals adhere to strict caste roles: queens lay eggs and workers take care of almost everything else, including offspring. In a new study, published in...

Sea levels in coastal areas can be affected by a number of factors: tides, winds, waves, and even barometric pressure all play a role in the ebb and flow of the ocean. For the first time, however, a...
