The potential threat of biological warfare with a specific agent is proportional to the susceptibility of the population to that agent. Preventing disease after exposure to a biological agent is partially a function of the immunity of the exposed individual. The only available countermeasure that can provide immediate immunity against a biological agent is passive antibody. Unlike vaccines, which require time to induce protective immunity and depend on the host’s ability to mount an immune response, passive antibody can theoretically confer protection regardless of the immune status of the host. Passive antibody therapy has substantial advantages over antimicrobial agents and other measures for postexposure prophylaxis, including low toxicity and high specific activity. Specific antibodies are active against the major agents of bioterrorism, including anthrax, smallpox, botulinum toxin, tularemia, and plague. This article proposes a biological defense initiative based on developing, producing, and stockpiling specific antibody reagents that can be used to protect the population against biological warfare threats.

Defense strategies against biological weapons include such measures as enhanced epidemiologic surveillance, vaccination, and use of antimicrobial agents, with the important caveat that the final line of defense is the immune system of the exposed individual. The potential threat of biological warfare and bioterrorism is inversely proportional to the number of immune persons in the targeted population. Thus, biological agents are potential weapons only against populations with a substantial proportion of susceptible persons. For example, smallpox virus would not be considered a useful biological weapon against a population universally immunized with vaccinia.

Vaccination can reduce the susceptibility of a population against specific threats provided that a safe vaccine exists that can induce a protective response. Unfortunately, inducing a protective response by vaccination may take longer than the time between exposure and onset of disease. Moreover, many vaccines require multiple doses to achieve a protective immune response, which would limit their usefulness in an emergency vaccination program to provide rapid prophylaxis after an attack. In fact, not all vaccine recipients mount a protective response, even after receiving the recommended immunization schedule. Persons with impaired immunity are often unable to generate effective response to vaccination, and certain vaccines may be contraindicated for them.

Circa 2019


The development of new so-called metamaterials could lead to dramatic advances in military technology, particularly the ability to hide from sensors—even the human eye. Metamaterials, engineered composites designed to manipulate the electromagnetic spectrum, could lead to “invisible” tanks and armored vehicles, submarines undetectable by sonar, and weapons with improved seekers and guidance systems.

The big caveat though is that metamaterials are currently pretty difficult to manufacture and are still years away from full-scale production.

A new article in the October issue of the U.S. Naval Institute Proceedings outlines potential military applications for metamaterials. Metamaterials of plastic and metal and engineered in lattice-like patterns up to a billionths of a meter in scale. The result is a surface or material that can manipulate an object’s magnetic or electrical field in ways traditional building materials cannot. This allows them to alter how energy waves across the electromagnetic spectrum (visual light, radar, radio, acoustic waves, etc.) interact with them with some pretty stunning implications.

I believe people are dying because the response to this is surreal. You can spend over $1.5 Trillion on an F-35 that has been grounded more times than grass, yet this is happening 😳. Cheap test kits were offered by startups, nanotech protective gear was offered by an Israeli startup. Yet for some reason bailing out Mar a Lago makes more sense.

The shortage of safety gear at one Manhattan hospital is so dire that desperate nurses have resorted to wearing trash bags — and some blame the situation for the coronavirus death of a beloved colleague.

The Defense Department will provide 5 million medical-grade air-filtering masks — 1 million of them available immediately — as well as 2,000 ventilators as it steps up its role in the U.S. response to the coronavirus pandemic, Secretary of Defense Mark Esper said.

The Pentagon can also make the Navy’s two hospital ships available on the East and West coasts, Esper told reporters Tuesday. But he emphasized that the ships and other military resources would best be able to treat some trauma cases to make room for coronavirus patients at civilian hospitals that are properly equipped to handle infections.

“They don’t have necessarily the space, the segregated spaces, you need to deal with infectious diseases,” Esper said at the Pentagon. “So one of the ways by which you could use either field hospitals, the hospital ships or things in between, is to take the pressure off of civilian hospitals when it comes to trauma cases, is to open up civilian hospital rooms for infectious diseases.”

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

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.
