Korea Is Testing Its New Jet Fighter

Posted by in category: military

You know, when you have North Korea at your side, it is better to always stay on the alert. And when your country’s coastline is washed by the Sea of Japan and the East China Sea, double attention is required. You guessed it right, we’re talking about the Republic of South Korea and its Air Force (ROKAF).
Today there are two American air bases on the territory of South Korea — Osan and Kusan, which are covered by the Patriot air defense system.
The total number of ROKAF and US Air Force fighters at all South Korean air bases is about 500 combat aircraft. Most of them are the 4th generation fighters that are about to become obsolete.
But if the airspace of your country is violated by China and Russia 10–15 times a year, you can’t rely solely on your allies. The only condition for relative peace is modern fighters.

Z-Pinch fusion-based nuclear propulsion

Posted by in categories: military, nuclear energy, space

Circa 2013

Fusion-based nuclear propulsion has the potential to enable fast interplanetary transportation. Due to the great distances between the planets of our solar system and the harmful radiation environment of interplanetary space, high specific impulse (Isp) propulsion in vehicles with high payload mass fractions must be developed to provide practical and safe vehicles for human space flight missions.

The Z-Pinch dense plasma focus method is a Magneto-Inertial Fusion (MIF) approach that may potentially lead to a small, low cost fusion reactor/engine assembly [1]. Recent advancements in experimental and theoretical understanding of this concept suggest favorable scaling of fusion power output yield [2]. The magnetic field resulting from the large current compresses the plasma to fusion conditions, and this process can be pulsed over short timescales (10−6 s). This type of plasma formation is widely used in the field of Nuclear Weapons Effects testing in the defense industry, as well as in fusion energy research. A Z-Pinch propulsion concept was designed for a vehicle based on a previous fusion vehicle study called “Human Outer Planet Exploration” (HOPE), which used Magnetized Target Fusion (MTF) [3] propulsion.

Eliminating dangerous bacteria with nanoparticles

Posted by in categories: biotech/medical, cyborgs, military, nanotechnology

Multi-resistant pathogens are a serious and increasing problem in today’s medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers at Empa and ETH Zurich are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale (“Inorganic nanohybrids combat antibiotic-resistant bacteria hiding within human macrophages”).

In the arms race “mankind against bacteria”, bacteria are currently ahead of us. Our former miracle weapons, antibiotics, are failing more and more frequently when germs use tricky maneuvers to protect themselves from the effects of these drugs. Some species even retreat into the inside of human cells, where they remain “invisible” to the immune system. These particularly dreaded pathogens include multi-resistant staphylococci (MRSA), which can cause life-threatening diseases such as sepsis or pneumonia.

Martin Rees and Frederick Lamb on humanity’s fate

Posted by in categories: alien life, cybercrime/malcode, evolution, military

Rees explained how his astronomy background meshes with his concern for humanity’s fate:

People often ask does being an astronomer have any effect on one’s attitude toward these things. I think it does in a way, because it makes us aware of the long-range future. We’re aware that it’s taken about 4 billion years for life to evolve from simple beginnings to our biosphere of which we are a part, but we also know that the sun is less than halfway through its life and the universe may go on forever. So we are not the culmination of evolution. Post-humans are going to have far longer to evolve. We can’t conceive what they’d be like, but if life is a rarity in the universe, then, of course, the stakes are very high if we snuff things out this century.

Bottom line: From nuclear weapons to biowarfare to cyberattacks, humanity has much to overcome. Martin Rees and Frederick Lamb discuss the obstacles we face as we look forward to humanity’s future on Earth.

The AI arms race has us on the road to Armageddon

Posted by in categories: military, robotics/AI

There is no putting the genie back in the bottle. The AI arms race is well underway and leading militaries worldwide do not want to be in second place or worse. Where this will lead is subject to conjecture. Clearly, however, the wars of the future will be fought and determined by AI more than traditional “military might.” The ethical use of AI in these applications remains an open-ended issue. It was within the mandate of the NSCAI report to recommend restrictions on how the technology should be used, but this was unfortunately deferred to a later date.

The AI arms race is speeding ahead in militaries around the world.

DARPA Develops Drone to Counteract Smaller Ones, Future War of Drones?

Posted by in categories: drones, military

There’s been a lot of talk lately about drones as a huge military asset. But, since everybody seems to be doing the same thing, the question becomes: how do we counteract them? The U.S. military is also focusing on drones as a threat and what are the best ways to tackle this threat. Aerial Dragnet has the answers.

Lockheed Martin wins $27 million contract modification for integration of DARPA’s Blackjack satellites

Posted by in categories: military, satellites

DARPA announced it has increased Lockheed Martin’s contract for satellite integration work for the Blackjack program by $27.3 million.

WASHINGTON — The Defense Advanced Research Projects Agency increased Lockheed Martin’s contract for satellite integration work for the Blackjack program by $27.3 million, the agency announced April 22.

DARPA a year ago selected Lockheed Martin as the satellite integrator for Blackjack, a project to demonstrate a network of small satellites in low Earth orbit for military communications, missile warning and navigation.

American Honey Still Contains Radioactive Fallout From Nuclear Tests Decades Ago

Posted by in categories: food, military, nuclear weapons

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.

Special Ops Soldier With Jetpack Boards Ship in Amazing Video

Posted by in category: military


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.
