Manhattan Emptied Out During the Pandemic. But Big Tech Is Moving In.

Facebook has just leased enough new office space in Manhattan to nearly triple its current local work force, including at one of the city’s most iconic buildings, the 107-year-old former main post office complex near Pennsylvania Station.

Apple, which set up its first office in New York a decade ago, is expanding to another building in Manhattan. And Google and Amazon are stitching together corporate campuses in the city more quickly than anywhere else in the world. Amazon paid roughly $1 billion in March for the iconic Lord & Taylor building on Fifth Avenue.

Despite a pandemic that has ravaged New York, hollowed out many of its office buildings and raised fundamental questions about its future, the four companies collectively known as Big Tech are all significantly expanding their footprint in the city, giving it a badly needed vote of confidence.

With fears that the virus could spike again in

Importance of moving activities outdoors and ensuring proper ventilation indoors stressed, as experts urge science community to clarify definitions — ScienceDaily

Scientists affiliated with leading research institutions across the U.S. state in a letter published Monday in the journal Science that researchers across disciplines must converge to deliver clear public health guidance about how SARS-CoV-2 is spread in the air.

The researchers write in the open letter that the scientific community must clarify the terminology used related to aerosols and droplets, and employ a more modern size threshold, rather than the existing one based on 1930s-era work. Authors include experts from the University of California San Diego, University of Maryland, Virginia Tech, and others.

Public health officials should make a clear distinction between droplets ejected by coughing or sneezing — which have inspired the social distancing mantra of six feet of separation between people — and aerosols that can carry the virus for much greater distances. Viruses in aerosols smaller than 100 microns can remain airborne in a confined space for

Fortem Technologies Adds New Capabilities to Autonomously Capture a Wider Array of Drone Threats, Including Faster Moving Fixed Wing Drones

Pleasant Grove, UT, Sept. 16, 2020 (GLOBE NEWSWIRE) — Fortem Technologies Inc., a leader in airspace security and defense for detecting and defeating dangerous drones, announced today advancements to its SkyDome® System software that allow the Fortem DroneHunter® to autonomously shift into one of three various modes to best defeat a threatening drone. DroneHunter, the world’s premier AI-driven interceptor drone, autonomously determines whether to chase, attack or defend against the threatening drone depending on the drone’s size, speed and trajectory. These advancements allow DroneHunter to pursue and safely capture an even wider range of drone threats including faster fixed wing drones.

When in defense mode, the DroneHunter maneuvers in front of the target drone, anticipating its approach. Once in range, DroneHunter fires the NetGun precisely as the target attempts to pass. The defensive mode position also facilitates a radically faster detect-to-capture-time, as the time previously required to get behind the
