The first-ever study of body condition in these whales had some concerning findings, including one individual that lost over 200 kilograms in just 10 weeks.

If were to reach another star, chemical propulsion will not get us there in any reasonable time frame. Were going to need a different propulsion technology, and one of the most promising seems to be a solar sail. These giant reflective surfaces form the basis of many interstellar missions. Combined with giant lasers pushing them, they can be accelerated to speeds unreachable by any other current technologies. However, according to a new paper available on arXiv from Chao Shen and Jiaze Li of the Harbin Institute of Technology, once those missions start reaching a significant percentage of the speed of light theyre going to run into a drag force from the light itself.

Updated SETI protocols continue to prohibit any response to a detected extraterrestrial signal, until international consultations take place.

You've seen "The Day After Tomorrow, right?

Blue holes may be a lighter hue than black holes, but they're similarly mysterious.

The board that accredits medical schools is poised to take away requirements that doctors learn about factors, such as income, neighborhood, and culture, that can affect medical treatment approaches. These requirements are necessary to ensure the highest quality of care.

Researchers have made a new biomaterial that has a similar tensile strength as a fruit roll-up and could help reduce waste produced from indoor decor.

The Romans were the first to wear clog-style footwear to the baths to protect their feet from the hot floor and to better navigate slippery surfaces.

Inflation is awkward, possibly not even a proper theory, and it has reigned over cosmology for forty years anyway. Here is what it claims, the flatness, horizon, and monopole problems it solves, the structure-formation prediction it nailed, and the deep problems it still cannot escape.

An international team led by astronomers at the University of Sydney hasuncoveredthe clearest evidence yet for the origin ofan unusual class ofcosmicsignals. In doing so, theyhave identifieda rare stellar system that is providing scientists with a natural laboratory to study extreme physics.

AI could soon use more water than we need to drink, UN report finds.

By taking general relativity into higher dimensions, a trio of physicists has proven that a mathematical pattern of ripples in space-time geometry could give rise to naked singularities and microscopic black holes.
