This physicist’s work adds a new twist to the tale of Dyson spheres.

And Earth-bound astronomers should be able to tell if someone is out there doing it, a physicist says.

A new University of Colorado Boulder study, published in the journal Experimental Physiology, helps explain why.

It found that people who sleep fewer than 7 hours per night have lower blood levels of three physiological regulators, or microRNAs, which influence gene expression and play a key role in maintaining vascular health.

The findings could potentially lead to new, non-invasive tests for sleep deprived patients concerned about their health, the authors said.

Scientists have used an X-ray laser to create the loudest possible underwater sound on Earth.

(Reuters) — The U.S. Postal Service on Tuesday started a two-week test transporting mail across three Southwestern states using self-driving trucks, a step forward in the effort to commercialize autonomous vehicle technology for hauling freight.

SpotMini autonomously navigates a specified route through an office and lab facility. Before the test, the robot is manually driven through the space so it can build a map of the space using visual data from cameras mounted on the front, back and sides of the robot. During the autonomous run, SpotMini uses data from the cameras to localize itself in the map and to detect and avoid obstacles. Once the operator presses ‘GO’ at the beginning of the video, the robot is on its own. Total walk time for this route is just over 6 minutes. (The QR codes visible in the video are used to measure performance, not for navigation.)

The picture of a “bullet train” speeding past Mount Fuji is an iconic image of modern Japan.

In recent years, however, Japan has lost the “world’s fastest train” title to China — if only by a few miles per hour. But now, Japan plans to reclaim that crown, with a new bullet train that will whisk between cities with journey times that rival passenger jets.

The Alfa-X train, unveiled by rail company JR East, will carry passengers at up to 224 miles per hour, outpacing the fastest Japanese bullet trains in commercial service today by almost 25 miles per hour.
