The $7.5 million investment for a new networked systems center of excellence comes as the Defense Department looks to advance its future joint war-fighting concept.
When Steamboat Geyser, the world’s tallest, started erupting again in 2018 in Yellowstone National Park after decades of relative silence, it raised a few tantalizing scientific questions. Why is it so tall? Why is it erupting again now? And what can we learn about it before it goes quiet again?
The University of Utah has been studying the geology and seismology of Yellowstone and its unique features for decades, so U scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearby spring. The findings are published in the Journal of Geophysical Research-Solid Earth.
“We scientists don’t really know what controls a geyser from erupting regularly, like Old Faithful, versus irregularly, like Steamboat,” says Fan-Chi Lin, an associate professor with the Department of Geology and Geophysics. “The subsurface plumbing structure likely controls the eruption characteristics for a geyser. This is the first time we were able to image a geyser’s plumbing structure down to more than 325 feet (100 m) deep.”
An ambitious project designed by a University of Arizona team aims to preserve humankind – and animal-kind, plant-kind and fungi-kind – in the event of a global crisis.
On March 122021 NASA’s Perseverance Rover continues to find safe place to deploy Mars Helicopter Ingenuity and collect Mars Samples. Rover’s latest pics from Mars show Helicopter’s shield attached to bottom of the rover. Perseverance will gather samples from Martian rocks and soil using its drill. The rover will then store the sample cores in tubes on the Martian surface. This entire process is called “sample caching”. Mars 2021 is the first mission to demonstrate sample collection on Mars. It could potentially pave the way for future missions that could collect the samples and return them to Earth for intensive laboratory analysis.
For the first flight, the helicopter will take off a few feet from the ground, hover in the air for about 20 to 30 seconds, and land. That will be a major milestone: the very first powered flight in the extremely thin atmosphere of Mars. After that, the team will attempt additional experimental flights of incrementally farther distance and greater altitude. After the helicopter completes its technology demonstration, Perseverance will continue its scientific mission.

Three species of shark that inhabit the twilit depths of the ocean just turned out to have been bioluminescent this whole time.
The kitefin shark, the blackbelly lanternshark, and the southern lanternshark have all been discovered to have softly glowing blue patterns on their skin, a first for sharks found in New Zealand waters.
Of those three, the kitefin shark, which grows up to 180 centimetres (5 feet 11 inches) long, is now the largest known bioluminescent shark in the world.
Facebook has announced a new AI project called Learn From Video, which will use public Facebook videos to train its machine learning models. The company is vague about future applications, but it says such models could be used to improve captions, search functions, and much more.
