What happens to marine life when oxygen is scarce
In September of 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually Senate confirms Kendall to be Air Force Secretary
Frank Kendall won confirmation from the Senate July 26 to be the 26th Secretary of the Air Force, placing an official with decades-long service in defense issues in the top civilian job at a time when the department is navigating new global challenges and wide-reaching modernization efforts.
The vote reflected both Kendall's well-known record in previous active duty and policy jobs and his Tesla quarterly profits top $1 bn for 1st time
US electric carmaker Tesla reported its first-ever quarterly profit above $1 billion Monday as it reiterated its 2021 production targets despite supply chain upheaval.
Record deliveries of electric cars during the period allowed Elon Musk's company to garner earnings of $1.1 billion in the quarter, up from $104 million in the year-ago period as revenues nearly doubled to $12.0 billion. 'Metaverse': the next internet revolution?
Imagine a world where you could sit on the same couch as a friend who lives thousands of miles away, or conjure up a virtual version of your workplace while at the beach.
Welcome to the metaverse: a vision of the future that sounds fantastical, but which tech titans like Facebook founder Mark Zuckerberg are betting on as the next great leap in the evolution of the internet.
The metavers Spacecom Leader Discusses the Value of Partnerships in Defending Space
Army Gen. James H. Dickinson said today that the role of the Space Force is to organize, man, train and equip space forces, while Spacecom employs those forces in operations.
Both Spacecom and the Space Force were created because of the threat from adversaries in the space domain and the need to protect and defend space assets from those adversaries, he said.
Dickinson noted that the Astronomers detect light from behind a black hole for the first time
Gas, dust and light that get sucked into a black hole are lost forever - so it shouldn't be possible to see light from behind a black hole.
But that's just what astronomers spotted while observing a supermassive black hole at the center of a galaxy 800 million light-years away.

ESA's Jupiter Icy moons Explorer, Juice, has successfully completed rigorous thermal tests simulating the extreme coldness of space and the warmth of the Sun at ESA’s test centre ESTEC, in The Netherlands.
The spacecraft underwent a month of round-the-clock testing and monitoring in the Large Space Simulator, which recreates the vacuum of space and is able to simulate both hot and cold space environments. The spacecraft was subjected to temperatures ranging from 250 degrees to minus 180 degrees Celsius, showing that it can survive its journey in space.
Juice will launch in 2022 to our Solar System’s largest planet.
First test of Europe's new space brain
ESA has successfully operated a spacecraft with Europe's next-generation mission control system for the first time. The powerful software, named the "European Ground System—Common Core' (EGS-CC), will be the 'brain' of all European spaceflight operations in the years to come, and promises new possibilities for how future missions will fly.
Rocket tanks of carbon-fiber–reinforced plastic are proven possible
Future rockets could fly with tanks made of lightweight carbon fiber reinforced plastic thanks to ground-breaking research carried out within ESA's Future Launchers Preparatory Program.
Building on earlier studies, MT Aerospace in Germany has demonstrated a novel design of a small scale tank made of a unique carbon-fiber reinforced plastic (CFRP) that is not only leak-proof with liquid hydrogen, but also compatible with liquid oxygen, without the use of a metal liner.
