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.

The US military and its contractors would be exempt.

Robots that are autonomous or semi-autonomous and carry weapons or offensive capabilities are often called armed robots. These robots can be employed in a variety of settings, including the military, law enforcement, industry, and security.

Today, many armed robots are controlled remotely by human operators who can keep a safe distance between themselves and the devices. This is particularly prevalent with military drones, as the operators control the aircraft and its weaponry from a distance, making the machines even more dangerous to civilians.
