In Billings, Montana, some healthcare professionals are using 3D printers to make reusable plastic face masks. The masks are then fitted with pieces of surgical masks which can be swapped out as needed.

The surgical masks are cut into smaller squares that can be clipped into the plastic mask to serve as a filter, Dusty Richardson, a neurosurgeon at the Billings Clinic told CNN.
“The filter can be used for a day and you can change it out the next day, but I do wash my mask out frequently,” Richardson said.

The plastic can be cleaned with soap and water, bleach and other disinfecting products. Richardson estimates healthcare workers can get 6 to 10 uses out of a single surgical mask...

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation Project, will help improve our understanding of the star formation process.

We know that stars such as the Sun are born from interstellar gas clouds. These interstellar gas clouds are difficult to observe in visible light, but emit strong radio wavelength, which can be observed by the Nobeyama 45-m Radio Telescope in Japan...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.

In the last two decades, thousands of planets have been found orbiting stars other than our Sun. Some of these planets orbit two stars, just like Luke Skywalker’s home Tatooine...

From a simple blood draw, microbial DNA may reveal who has cancer and which type, even at early stages. When Gregory Poore was a freshman in college, his otherwise healthy grandmother was shocked to learn that she had late-stage pancreatic cancer. The condition was diagnosed in late December. She died in January.

“She had virtually no warning signs or symptoms,” Poore said. “No one could say why her cancer wasn’t detected earlier or why it was resistant to the treatment they tried...
