The Army is looking at its Plasma Acoustic Shield System as a checkpoint defender, for now. But the original idea – and the long-term goal of the project – is to have it be the first baby step towards a portable, lethal laser weapon.

The effort, by the U.S. Army’s Advanced Energy Armaments Systems Division and Stellar Photonics, has a lot in common with another military laser project: the Pulsed Energy Projectile being developed by Mission Systems for the Marines. But there are three key differences. The current PEP is a big (450 lb) chemical laser with a limited number of shots, whereas PASS is a small solid-state laser that just needs electricity. The PEP creates plasma by vaporising the outer layer surface it hits (such as your shirt), whereas PASS can create plasma in mid-air by focusing to a point. And PEP fires a single pulse, whereas PASS uses a double pulse which Stellar claim is far more efficient at creating a shockwave.

You can get some idea from the Small Business Initiative Proposal the company submitted in ‘04 for a “Man-portable Integrated Laser Assault Rifle”:

:ooooo.

China’s military and paramilitary forces have been employing lasers with increasing frequency since at least 2018.

Protein mapping finds 69 potential treatments for COVID-19.

Many are FDA-approved drugs that could be repurposed.

NASA, one of SpaceX’s biggest customers, also prohibits its employees from using Zoom, said Stephanie Schierholz, a spokeswoman for the U.S. space agency.

The Federal Bureau of Investigation’s Boston office on Monday issued a warning about Zoom, telling users not to make meetings on the site public or share links widely after it received two reports of unidentified individuals invading school sessions, a phenomenon known as “zoombombing.”

Investigative news site The Intercept on Tuesday reported that Zoom video is not end-to-end encrypted between meeting participants, and that the company could view sessions.

Retired astronaut Chris Hadfield is spending lockdown searching for a better test for COVID-19, rewiring his stove, and talking to Euronews about what isolation means — and how to deal with it.

Dozens of other teams around the world have potential vaccines in development.

But the Pittsburgh research is the first study on a Covid-19 vaccine candidate to be published after critique from fellow scientists at outside institutions.

Can we build a better world with the lessons learned around this pandemic?

There is discussion that globalism will give way to community resilience and local digital manufacture, storage and transportation to provide abundant resources for normal and unanticipated needs.

Cells will ramp up gene expression in response to physical forces alone, a new study finds. Gene activation, the first step of protein production, starts less than one millisecond after a cell is stretched—hundreds of times faster than chemical signals can travel, the researchers report.

The scientists tested forces that are biologically relevant—equivalent to those exerted on human cells by breathing, exercising or vocalizing. They report their findings in the journal Science Advances.

“We found that force can activate genes without intermediates, without enzymes or signaling molecules in the cytoplasm,” said University of Illinois mechanical science and engineering professor Ning Wang, who led the research. “We also discovered why some genes can be activated by force and some cannot.”
