Congestion in LEO is on its way up, and in response, the US military is looking to move down.
The Defense Advanced Research Projects Agency (DARPA) has tapped RF-powered in-space propulsion pioneer Phase Four to develop and build a thruster that utilizes the thin air in VLEO as propellant.
While an estimated 5 million Americans live with a disability that is related to traumatic brain injury (TBI), there are few treatment options for TBIs, which can affect people in a number of occupations like professional sports or some military positions, as well as anyone who suffers head trauma. But scientists have now found that a protein called TDP-43 may promote nerve damage immediately following an injury. When another protein was blocked in a mouse model and in human cell lines, this TDP-43-mediated damaged was prevented and some cell death was halted. These findings, which were reported in Cell Stem Cell, could help scientists develop treatment options for TBIs.
“There’s really nothing out there that can prevent the injury or trauma to the brain that cause nerve cell damage,” said corresponding study author Justin Ichida of the University of Southern California. “In more acute stages, patients can have difficulty concentrating and have extreme sensitivity to light and noise. Long term, there is a strong correlation between traumatic brain injury and neurodegenerative diseases, which can ultimately be fatal.”
The development of electromagnetic catapults on China’s Fujian aircraft carrier began in 2001, which drew experience from the Shanghai Maglev Train project at the time. Land-based testing of the electromagnetic catapult for this Type 3 aircraft carrier can be traced back to 16 years ago. China has kept quiet about it, but satellite images from Western companies unveiled the truth.

The Food and Drug Administration has approved a blood test to detect concussion that produces results in minutes rather than hours — a breakthrough that could help expedite treatment for service members with traumatic brain injuries, according to the U.S. Army and Abbott Laboratories, the…

“This can help get the most severely injured service members to neurosurgeons faster and ultimately save lives,” Lt. Col. Bradley Dengler, neurosurgical consultant to the U.S. Army Office of the Surgeon General, said in a release.
In science fiction, holograms are used for anything from basic communications to advanced military weaponry. In the real world, 3D holographic displays have yet to break through to everyday products and devices. That’s because creating holograms that look real and have significant fidelity requires laser emitters or other advanced pieces of optical equipment. This situation has stymied commercial development, as these components are complex and expensive.
More recently, research scientists were able to create realistic 3D holographic images without lasers by using a white chip-on-board light-emitting diode. Unfortunately, that method required two spatial light modulators to control the wave fronts of the emitted light, adding a prohibitive amount of complexity and cost.
Now, those same scientists say they have created a simpler, more cost-effective way to create realistic-looking 3D holographic displays using only one spatial light modulator and new software algorithms. The result is a simpler and cheaper method for creating holograms that an everyday technology like a smartphone screen can emit.
As computer vision (CV) systems become increasingly power and memory intensive, they become unsuitable for high-speed and resource deficit edge applications — such as hypersonic missile tracking and autonomous navigation — because of size, weight, and power constraints.
At the University of Pittsburgh, engineers are ushering in the next generation of computer vision systems by using neuromorphic engineering to reinvent visual processing systems with a biological inspiration — human vision.
Rajkumar Kubendran, assistant professor in Pitt’s Swanson School of Engineering and senior member at the Institute of Electrical and Electronics Engineers (IEEE), received a Faculty Early Career Development (CAREER) award from the National Science Foundation (NSF) for his research on energy-efficient and data-efficient neuromorphic systems. Neuromorphic engineering is a promising frontier that will introduce the next generation of CV systems by reducing the number of operations through event-based computation in a biology-inspired framework.
A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace’s aircraft does go supersonic on a later date, it will be powered by a Rotating Detonation Rocket Engine (RDRE).
Supersonic drones may sound like something bleeding edge, but they’re surprisingly old hat as a basic concept. As far back as the early 1950s, the US Air Force was fielding remote-controlled supersonic jets for targets to test air defenses, as platforms for reconnaissance in dangerous areas, or as weapons armed with conventional or nuclear warheads.

A team of researchers from China, who are originally engaged in hypersonic missile development, have developed a mechanical sensor that can boost the safety on the country’s high-speed rail network.
As per an article in the South China Morning Post, the scientists have proposed using a high-sensitivity technology to paint a complete picture of every turn of the train’s wheels.
