As expected, various samples of fruits, nuts, and other foods revealed very faint traces of cesium-137 when measured with a gamma detector, but even Kaste wasn’t prepared for what happened when he ran the same test with a jar of honey from a North Carolina farmer’s market.


Traces of radioactive fallout from nuclear tests in the 1950s and 1960s can still be found in American honey, new research reveals.

The radioactive isotope identified, cesium-137, falls below levels considered to be harmful – but the amounts measured nonetheless emphasize the lingering persistence of environmental contaminants in the nuclear age, even a half-century after international bomb tests ended.

“There was a period in which we tested hundreds of nuclear weapons in the atmosphere,” lead researcher Jim Kaste, an environmental geochemist at William & Mary university in Williamsburg, Virginia, explained last year in comments about the research.

Woah.


In a new video released by jetpack maker Gravity Industries, a jetsuit-wearing special ops soldier from the Netherlands Maritime Special Operations Force can be seen boarding a ship — by flying there from a nearby pursuit vessel.

It’s a spectacular demonstration of Gravity Industries’ flying technology. Rather than having to pursue and approach the ship in the tailing vessel, the jetpack-enhanced soldier simply takes to the skies and effortlessly lands on the deck of the ship — in a fraction of the time boarding would have taken otherwise.

Gravity has quickly emerged as one of the biggest players in the jetpack field over the last few years, offering its jetsuit technologies to first responders and military forces around the world. It has even allowed journalists to give the suit a test drive, albeit with safety tethers.

The Art Of Human Care For Covid-19 — Dr. Hassan A. Tetteh MD, Health Mission Chief, U.S. Department of Defense (DoD), Joint Artificial Intelligence Center, The Pentagon.


Dr. Hassan A. Tetteh, MD, is the Health Mission Chief, at the Department of Defense (DoD) Joint Artificial Intelligence Center, serving to advance the objectives of the DoD AI Strategy, and improve war fighter healthcare and readiness with artificial intelligence implementations.

Dr. Tetteh is also an Associate Professor of Surgery at the Uniformed Services University of the Health Sciences, adjunct faculty at Howard University College of Medicine, a Thoracic Staff Surgeon for MedStar Health and Walter Reed National Military Medical Center, and leads a Specialized Thoracic Adapted Recovery (STAR) Team, in Washington, DC, where his research in thoracic transplantation aims to expand heart and lung recovery and save lives.

In the past, Dr. Tetteh has served as Chief Medical Informatics Officer, United States Navy, and Division Lead for Futures and Innovation at Navy Medicine’s Headquarters, a Command Surgeon for the National Defense University, and as a Robert Wood Johnson Health Policy Fellow, assigned to the U.S. Congress, Congressional Budget Office, (CBO).

Dr. Tetteh served as Ship’s Surgeon and Director of Surgical Services for the USS Carl Vinson, deployed as a trauma surgeon to Afghanistan’s Helmand and Nimroz provinces, and has supported special joint forces missions to South America, the Middle East, the South Pacific, Australia, and Africa. He earned both the Surface Warfare Medical Department Officer and Fleet Marine Force Qualified Officer designations, and his military honors include two Meritorious Service Medals and the Joint Service Commendation Medal.

Beyond Cislunar

Indeed, AFRL last Thursday held a classified stakeholder meeting to discuss research and development needed to underpin future military operations beyond the traditional near-Earth orbits used today, according to DoD officials. Neither AFRL nor Space Command would provide any details whatsoever about the meeting — not even a list of participants.

Sean Kirkpatrick, who represents the DNI at Space Command’s Joint Task Force-Space Defense (JTF-SD), said last Tuesday the “summit” was focused not just on R&D needed to counter potential adversary activities in cislunar space, but also “all around the sphere of the Earth, not necessarily in the direction of the Moon.”

The Space Development Agency is considering buying its next 150 satellites from three different vendors.


WASHINGTON — The Pentagon’s Space Development Agency is considering buying its next 150 satellites from three different vendors, but that could change after the agency evaluates companies’ bids, SDA director Derek Tournear said April 14.

Speaking at the Washington Space Business Roundtable, Tournear said a request for proposals will be issued in August for the agency’s Transport Layer Tranche 1 — a network of hundreds of communications satellites in low Earth orbit projected to start launching in late 2024.

The request will be for 150 satellites but SDA has not yet decided how that order will be divvied up. “There is probably three awards for those 150 satellites, but we’re not wed to three,” Tournear said. “Three is not a magic number. I’m really interested in industry feedback when they see our acquisition strategy.”

As well as Kronshtadt, many other Russian enterprises in the military-industrial complex are developing drones for deployment on the front lines. For example, aircraft manufacturer Sukhoi has teamed up with defense company Mikoyan to build the Okhotnik-B, which will have a top speed of 1000 km/h. Another aerospace company, called OKB Sokol, has developed a UAV named Altius, due to be delivered to the Russian Army this year.


A Russian company is building the country’s first-ever specialized factory solely for manufacturing unmanned aerial vehicles (UAVs). It plans to mass-produce military drones, like those deployed by the Russian Army in Syria.

The 45000-square-meter plant, under construction in the town of Dubna near Moscow, will cost at least four billion rubles ($52 million) and will create jobs for more than 1500 people. If all goes to plan, it will be built in record time, with the launch of production scheduled for November 2021.

The company, called ‘Kronshtadt Group,’ is the developer and manufacturer of the Inokhodets UAV, also known as the Orion. This medium-altitude drone, which is capable of flying for a whole day, can carry a payload of up to 200kg, and has already seen action in the Middle East.
