Fish and sharks living in the open ocean are impacted more by human pressure than their seabed-dwelling counterparts, according to a new study from The University of Western Australia.

Mitochondria are organelles that are known for providing the energy currency that fuels chemical reactions within cells, but they are also involved in other important processes vital for cell health including the innate immune response to pathogens like v

Proteins not only carry out the functions that are critical for the survival of cells, but also influence the development and progression of diseases. To understand their role in health and disease, researchers study the three-dimensional atomic structure

Brown bears foraging for food in the Shiretoko Peninsula of Hokkaido, Japan, have been disrupting tree growth in artificial conifer forests, according to a new study published in Ecology. Researchers compared soil and tree samples from human-forested plot

Antibiotic resistance is a significant and growing medical problem worldwide. Researchers at the Marine Biological Laboratory (MBL) and collaborators have found a novel genetic arrangement that may help a common bacterium in the human gut, Bacteroides fra

Asian elephants loudly mourn and bury their dead calves, according to a study by Indian scientists that details animal behavior reminiscent of human funeral rites.

An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark—and within just two minutes.

Put the word "evolution" into Google images and the results are largely variations on one theme: Ralph Zallinger's illustration, March of Progress. Running left to right, we see a chimp-like knuckle walker gradually becoming taller and standing

Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. Th

Drug development is currently an extremely long, expensive and inefficient process. Findings generated in a lab are often very hard to replicate once translated into animal models or in humans.

Researchers have shown that inedible species of butterfly that mimic each others' color patterns have also evolved similar flight behaviors to warn predators and avoid being eaten.

Thermal adaptation is the ability of organisms to adjust their life history traits as the temperature changes. In the case of mosquitoes, these traits can determine their risk of transmitting mosquito-borne diseases and how this risk might change in the f
