O.,o circa 2014.

Researchers in China are reporting that they’ve taken a big step towards creating a supersonic submarine. This technology, which could just as easily be applied to weaponized torpedoes as military or civilian submarines, could theoretically get from Shanghai to San Francisco — about 6,000 miles — in just 100 minutes. If all this doesn’t sound crazy enough, get this: This new advance by the Chinese is based on supercavitation, which was originally developed by the Soviets in the ’60s, during the Cold War.

As you may already know, it’s a lot harder for an object to move quickly through water than air. This is mostly due to increased drag. Without getting into the complexities of fluid dynamics, water is simply much thicker and more viscous than air — and as a result it requires a lot more energy for an object to push through it. You can experience the increased drag of water yourself next time you’re in a swimming pool: Raise your hand above your head, and then let it fall towards the water. (Or alternatively, if there are people sunbathing nearby, do a belly flop.)

Anyway, much like a small-engined car is ultimately limited by its ability to cut through wind resistance (drag), a submarine or torpedo needs insane amounts of power to achieve high velocity through water. This is why, even in 2014, most submarines and torpedoes can’t go much faster than 40 knots (~46 mph). Higher speeds are possible, but it requires so much power that it’s not really feasible (torpedoes only have so much fuel).

The super-charged face scanning tech is costing the military at least $4.3 million.

The United States Army is currently building a super-charged facial recognition system — tech that could be ready for action as soon as next year.

The system, as described in a new One Zero story, analyzes infrared images of a person’s face to see if they’re a match for anyone on a government watchlist, such as a known terrorist. Not only will the finished system reportedly work in the dark, through car windshields, and even in less-than-clear weather conditions — but it’ll also be able to ID individuals from up to 500 meters away.

Army Agreements

One Zero tracked down two military contracts for the development of the tech.

DARPA, the Defense Advanced Research Projects Agency that’s responsible for developing emerging technologies for the U.S. military, is building a new high-tech spacecraft — and it’s armed. In an age of Space Force and burgeoning threats like hunter-killer satellites, this might not sound too surprising. But you’re misunderstanding. DARPA’s new spacecraft, currently “in the thick of it” when it comes to development, is armed. As in, it has arms. Like the ones you use for grabbing things.

Armed robots aren’t new. Mechanical robot arms are increasingly widespread here on Earth. Robot arms have been used to carry out complex surgery and flip burgers. Attached to undersea exploration vehicles, they’ve been used to probe submerged wrecks. They’ve been used to open doors, defuse bombs, and decommission nuclear power plants. They’re pretty darn versatile. But space is another matter entirely.

If it wins FDA approval next year, the two-part sensor could help spot new infections weeks before symptoms begin to show.

Why are pandemics so hard to stop? Often it’s because the disease moves faster than people can be tested for it. The Defense Department is helping to fund a new study to determine whether an under-the-skin biosensor can help trackers keep up — by detecting flu-like infections even before their symptoms begin to show. Its maker, Profusa, says the sensor is on track to try for FDA approval by early next year.

The sensor has two parts. One is a 3mm string of hydrogel, a material whose network of polymer chains is used in some contact lenses and other implants. Inserted under the skin with a syringe, the string includes a specially engineered molecule that sends a fluorescent signal outside of the body when the body begins to fight an infection. The other part is an electronic component attached to the skin. It sends light through the skin, detects the fluorescent signal and generates another signal that the wearer can send to a doctor, website, etc. It’s like a blood lab on the skin that can pick up the body’s response to illness before the presence of other symptoms, like coughing.

A quantum sensor could give Soldiers a way to detect communication signals over the entire radio frequency spectrum, from 0 to 100 GHz, said researchers from the Army.

Such wide spectral coverage by a single antenna is impossible with a traditional receiver system, and would require multiple systems of individual antennas, amplifiers and other components.

In 2018, Army scientists were the first in the world to create a quantum receiver that uses highly excited, super-sensitive atoms—known as Rydberg atoms—to detect communications signals, said David Meyer, a scientist at the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. The researchers calculated the receiver’s channel capacity, or rate of data transmission, based on , and then achieved that performance experimentally in their lab—improving on other groups’ results by orders of magnitude, Meyer said.

Analysis: there have been reports of recent incursions of Russian bombers like the Tupolev TU–95 in airspace controlled by Ireland

There have been a number of recent incursions into Irish controlled airspace by the Russian air force. Most recently Tupolev TU–95, the so called “Bear” strategic bomber aircraft, triggered UK Royal Air Force fighter jets to scramble in order to confront the Russian aircraft. Reliable sources indicate that there is an agreement between the UK and Ireland permitting the Royal Air Force to enter Irish airspace if deemed necessary, though the specific nature of this arrangement is not clear.

Like much of Russia’s current military equipment, the Tupolev bombers are quite old, having come into service in the early 1950s. Although it is the only propeller powered bomber still in operational use today, it is far from obsolete and, like the United States B-52 bomber, it is planned to be in service for some time to come.

A new approach would use RNA or DNA to help the body develop antibodies to the rapidly spreading illness.

A U.S. military research program that seeks a new way to boost a body’s immunity to viruses could change how governments and militaries prepare for pandemics — and might even arrive soon enough to help with the COVID −19 outbreak.

DARPAs Pandemic Prevention Platform isn’t looking to create a vaccine, which can take years to produce and weeks to take effect in the body. Rather, the goal is to identify the specific monoclonal antibodies that the body naturally produces when it encounters a virus, and then trick the body into producing the one that guards against a specific illness. That could serve as a temporary, months-long shield that can protect the individual from the pathogen until a vaccine can be brought online.
