You are looking for krill in the Santa Barbara Channel. While this area is full of fish, kelp forests, seaweed beds, and other underwater life, it…

Fluids thicken at the speed of light: new theory extends Einstein’s theory of relativity to real fluids
Credit: CC0 Public Domain Special relativity has many surprising and counterintuitive effects, the most famous of which are length reduction and time dilation. If an object moves with a velocity relative to an observer that is a non-negligible fraction of the speed of light, the length of the object in the direction of movement will appear to the observer to…

Not too big, not too small: Why it’s the ideal size for modern people to speed up.
The speed and size pattern of running animals (blue) shows that intermediate-sized species (such as cheetahs) are usually the fastest. Resizing the computer-generated human model (right) from a mouse to a horse (orange dots) shows the same pattern, revealing the underlying biomechanical reasons. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52924-z The fastest animal on land is the cheetah, which can reach…

New data science tools dramatically speed up environmental molecular analysis
Source: Nature Protocols (2024). DOI: 10.1038/s41596-024-01046-3 A research team led by scientists at the University of California, Riverside has developed a computational workflow for analyzing large data sets in the field of metabolomics, the study of small molecules found in cells, biofluids, tissues and entire ecosystems. Recently, the team applied this new computational tool to analyze contaminants in ocean waters…

Physicists reveal that tailwinds have little effect on cycling speed
Author Martin Beer in an aerodynamic tuck, a cycling position that reduces drag. Credit: Martin Beer In the cycling world, “To Everest” means cycling up and down the same mountain, reaching a total altitude of Everest’s 8,848 metres. After a new “Everesting” bicycle record was set a few years ago, social media erupted with debate about the strong tailwind (5.5…
