Computer performance is measured in FLOPS, or floating-point operations per second. The first supercomputer, which was developed in 1964, could run 3,000,000 FLOPS, i.e., 3 megaFLOPS. Exa means 18 zeros, meaning 1,000,000,000,000,000,000 FLOPS. An exascale computer can perform that many operations — something that is almost impossible to imagine.

Now, there is a huge advantage to commanding that kind of computing power in today’s world. Here is what the same McKinsey report says: “Exascale computing could allow scientists to solve problems that have until now been impossible. With exascale, exponential increases in memory, storage, and compute power may drive breakthroughs in several industries: energy production, storage, transmission, materials science, heavy industry, chemical design, AI and machine learning, cancer research and treatment, earthquake risk assessment, and many more.”

Put simply, China now may have the computing power at its disposal to match, or even overtake, technology leaders like the United States in several areas that could be key to becoming the dominant economic and military power in the world. China could also pair its advances in artificial intelligence with this mind-boggling computering power and achieve technological and military dominance quite quickly.

The US has embarked on a program to develop electronic-warfare drone swarms, the latest in its multiple projects to master what could potentially be war-winning AI and drone technology, though with significant operational and strategic implications and risks.

This month, Breaking Defense reported that the US Navy is seeking industry and government agencies to participate in a July 2024 exercise called Silent Swarm 2024, which aims to demonstrate early-stage unmanned systems’ capabilities to fight on the electromagnetic battlefield.

Breaking Defense notes that the event, hosted by Naval Surface Warfare Center Crane, will showcase “swarming, small, attritable” unmanned systems capable of distributed electromagnetic attack, deception, and digital payload delivery, with the tech must be within readiness levels (TRL) two to five, with higher numbers indicating more advanced systems.

Traumatic brain injury (TBI) is a leading cause of long-term disability and premature death, especially among military personnel and those playing contact sports. Substantial research has examined acute and chronic neurological consequences of TBI; however, non-neurological conditions associated with TBI are understudied.

A new review paper by investigators from Mass General Brigham presents key findings on long-term associations between TBI and cardiovascular disease, highlighting that nervous system dysfunction, neuroinflammation, changes in the brain-gut connection, and post-injury comorbidities may elevate risk of both cardiovascular and cognitive dysfunction in TBI survivors compared to the general population.

The review, published in The Lancet Neurology, emphasizes the need for future cardiovascular research, surveillance and intervention in TBI survivors.

Space Warfare concepts from science fiction often involve war between planets, and we will discuss the science of that, and war inside a fully colonized solar system or Dyson Swarm.

NASA is edging closer to the conclusion of its ambitious seven-year mission, aiming to prevent a catastrophic collision of a massive asteroid named Bennu with Earth. Recent findings have indicated that there’s a 1 in 2,700 chance of Bennu slamming into Earth on September 24, 2182.

Roughly the size of the iconic Empire State Building, Bennu spans about a third of a mile wide. The potential aftermath of its predicted collision with Earth could equate to the explosive energy of 22 atomic bombs.

The asteroid makes its presence felt by passing Earth approximately every six years. However, scientists anticipate that its most perilous close encounter could be a mere 159 years away.

The Pentagon’s Defense Advanced Research Projects Agency (DARPA) has chosen Boeing to develop a prototype and conduct flight testing of its upcoming Glide Breaker hypersonic interceptor. An interceptor is a weapon designed to destroy other missiles mid-flight before they reach their targets. Glide Breaker is a planned huge leap forward in missile interceptors, as it’s designed to target the highly maneuverable class of weapons known as hypersonic glide vehicles, which are able to execute abrupt “zig-zag” maneuvers as they glide unpowered through Earth’s atmosphere at speeds of Mach 5 and higher. (Mach 1 is the speed of sound — about 767 mph, or 1,234 kph, at sea level.) This combination of speed and maneuverability makes such weapons much harder to defend against than traditional missiles.
