Scientists have developed six lines of humanized mice that can serve as valuable models for studying human cases of COVID-19.

Humans slow their own speech when talking to their dogs, and this slower tempo matches their pets' receptive abilities, allowing the dogs to better understand their commands, according to a new study.

A new survey of climate experts reveals that a majority believes the Earth to be headed for a rise in global temperatures far higher than the 2015 Paris Agreement targets of 1.5 to well-below 2 degrees Celsius. It also shows that two-thirds of respondents believe we may succeed in achieving...

Inspired by the dynamic color-changing properties of squid skin, researchers have developed a method to manufacture a heat-adjusting material that is breathable and washable and can be integrated into flexible fabric. The composite material operates in the infrared spectrum and consists of a polymer covered with copper islands. Stretching the...

A new study provides compelling evidence that Canada lynx populations in Interior Alaska experience a 'traveling population wave' affecting their reproduction, movement and survival. This discovery could help wildlife managers make better-informed decisions when managing one of the boreal forest's keystone predators.

A Federal Emergency Management Agency (FEMA) program provides important flood insurance relief, researchers say. But due to its design, it's used more in communities with greater means to protect themselves, while lower-resourced areas benefit less.

A gene that limits cellular damage could be the key to surviving prolonged cold exposure.

Palladium, a rare metallic element, can rapidly generate water from hydrogen and oxygen. Researchers witnessed this process at the nanoscale for the first time with an electron microscope. By viewing the process with extreme precision, researchers discovered how to optimize it to generate water at a faster rate. Process could...

A new study shows that bitter tasting protein fragments (peptides) are produced in the stomach during the digestion of the natural sweetener thaumatin. In a cellular test system, the peptides are able to stimulate the acid secretion of human stomach cells and influence inflammatory reactions.
