Sea otters are the smallest marine mammal. As cold-water dwellers, staying warm is a top priority, but their dense fur only goes so far. We have long known that high metabolism generates the heat they need to survive, but we didn't know how they were producing the heat -- until now.

Researchers recently discovered that sea otters' muscles use enough energy through leak respiration, energy not used to perform tasks, that it accounts for their high metabolic rate. The finding explains how sea otters survive in cold water.

Evidence suggests that what happens in one generation--diet, toxin exposure, trauma, fear--can have lasting effects on future generations. Scientists believe these effects result from epigenetic changes that occur in response to the environment and turn genes on or off without altering the genome or DNA sequence.

Players of the popular game Red Dead Redemption 2 learn how to identify real American wildlife, new research shows.

The game, set in the American West in 1899, features simulations of about 200 real species of animals.

The new study, by the University of Exeter and Truro and Penwith College, challenged gamers to identify photographs of real animals.

On average, RDR2 players were able to identify 10 of 15 American animals in a multiple-choice quiz - three more than people who had not played the game.

Eyewitnesses can identify perpetrators more accurately when they are able to manipulate 3D images of suspects, according to a new study.

A team of researchers in the University of Birmingham's School of Psychology developed and tested new interactive lineup software which enables witnesses to rotate and view lineup faces from different angles.

When the eyewitnesses were able to rotate the image to match the alignment of the face in their memory, they were more likely to accurately pick out the criminal from the lineup.

A new study by Thomas Le Barbanchon and Julien Sauvagnat, two Associate Professors at Bocconi University, published in the Journal of the European Economic Association, finds that electoral districts with a larger gender pay gaps show favoritism toward male political candidates in Parliamentary elections, with fewer female candidates on the ballot.

Researchers at the University of Freiburg and the University of Stuttgart have developed a new process for producing movable, self-adjusting materials systems with standard 3D-printers. These systems can undergo complex shape changes, contracting and expanding under the influence of moisture in a pre-programmed manner. The scientists modeled their development based on the movement mechanisms of the climbing plant known as the air potato (Dioscorea bulbifera).

A research team at Washington University School of Medicine in St. Louis has identified potential new treatment targets for Alzheimer's disease, as well as existing drugs that have therapeutic potential against these targets.

A new study presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) and published in The Lancet Microbe, shows that antibodies generated by CoronaVac, an inactivated COVID-19 vaccine, work less well against the P.1 Brazil (Gamma) variant.

A new UBC Sauder School of Business study shows that depending on how employees understand their boss' motivation, employees can feel anger or guilt, and consequently, react differently to abusive supervision.

Former Apple CEO Steve Jobs was a famously harsh corporate leader, one who pushed his employees to extremes to achieve the company's lofty aims.

More than a third of coal miners and former coal miners suffering from black lung disease struggle with depression, and more than one in 10 has recently considered suicide, a new study finds.

Evidence from an ancient eggshell has revealed important new information about the extreme climate change faced by human early ancestors.

The research shows parts of the interior of South Africa that today are dry and sparsely populated, were once wetland and grassland 250,000 to 350,000 years ago, at a key time in human evolution.

Eight pieces of salmon-based maki, nigiri or sashimi or maki unagi (eel) is the safest combination of sushi for adult and adolescent populations. That is one of the findings of TecnATox (Centre for Environmental, Food and Toxicological Technology), a joint research group from the URV and the Pere Virgili Health Research Institute (IISPV), which has analysed the presence of arsenic and various heavy metals in sushi. The consumption of sushi has increased significantly since the start of the 21st century, as has the number of restaurants offering it throughout the region.

The rationale for the research is in the fact that despite the high number of recognized Indigenous groups who are struggling to maintain their languages, cultures, and identities in Russia, there is little research done on the matters of cultural and linguistic revitalization. This study sought to address this gap by exploring the views of two Indigenous groups, Karelian and Mari, on the development of their Indigenous languages and educational strategies to protect and revive their languages.
