China Tested A Fractional Orbital Bombardment System That Uses A Hypersonic Glide Vehicle: Report

That layer would be absolutely essential in trying to defend against a FOBS, that is if a defense at all is actually feasible or even strategically sound. We are not talking about a rogue state here with a few advanced ballistic missiles. China would be able to deploy dozens or even hundreds of these at once. At a certain point, kinetic defenses against such a capability become a losing proposition and a very costly one at that.
Still, this was an early test aboard a full-on rocket used for traditional space access missions. It will take China some time to perfect such a system and package it in a quickly deployable militarized configuration. Major thermal and ablative issues also must be overcome, among others, but it’s not like China hasn’t been working diligently in the hypersonic boost-glide vehicle realm for many years.
Regardless, if this report ends up being fully accurate, one thing is likely: New calls for hugely expensive missile defense capabilities will be ringing loud and often on Capitol Hill, as well as demands to do whatever possible to bring China to the bargaining table in hopes of obtaining some type of strategic arms limitation treaty.

Spectroradiometer “Ray Guns” Let Scientists Use Light Instead of DNA To Tell Plants Apart
Posted by Quinn Sena in category: biotech/medical
The central principle of superconductivity is that electrons form pairs. But can they also condense into foursomes? Recent findings have suggested they can, and a physicist at KTH Royal Institute of Technology today published the first experimental evidence of this quadrupling effect and the mechanism by which this state of matter occurs.

Gene editing can turn storage fat cells into energy-burning fat cells
Posted by Quinn Sena in categories: bioengineering, biotech/medical, genetics, health
A team of researchers at UT Southwestern Medical Center’s Touchstone Diabetes Center have successfully used CRISPR gene editing to turn fat cells normally used for storage into energy-burning cells.
“It’s like flipping a switch. We removed the ‘brake’ on the energy burning pathway in fat cells by engineering a mutation that disrupts the interaction between a single pair of proteins,” said study leader Rana Gupta, Ph.D., Associate Professor of Internal Medicine. “Our research demonstrates that releasing this brake in fat cells can potentially help make existing diabetes medications much more effective.”
The research at UT Southwestern, ranked as one of the nation’s top 25 hospitals for diabetes and endocrinology care, is published in Genes and Development and supported by the National Institutes of Health.

Gamma rays from lightning found to create antimatter in the air
Posted by Quinn Sena in category: climatology
Circa 2017
Lightning is one of Earth’s most energetic events, but there’s much more to it than just a flashing fork and the rumble of thunder. Lightning strikes have been known to generate gamma rays, and now a team of Japanese researchers has found that those bursts can create photonuclear reactions in the atmosphere, resulting in the production – and annihilation – of antimatter.
Bursts of gamma rays from lightning were first detected in 1,992 thanks to NASA’s Compton Gamma-ray Observatory. Since then, these Terrestrial Gamma-ray Flashes (TGF) have been studied intently, and the new research out of Kyoto University has found an unexpected cause of some of the signals.

Deep North, which uses AI to track people from camera footage, raises $16.7M
Posted by Gemechu Taye in categories: biotech/medical, information science, robotics/AI, security
Deep North, a Foster City, California-based startup applying computer vision to security camera footage, today announced that it raised $16.7 million in a Series A-1 round. Led by Celesta Capital and Yobi Partners, with participation from Conviction Investment Partners, Deep North plans to use the funds to make hires and expand its services “at scale,” according to CEO Rohan Sanil.
Deep North, previously known as Vmaxx, claims its platform can help brick-and-mortar retailers “embrace digital” and protect against COVID-19 by retrofitting security systems to track purchases and ensure compliance with masking rules. But the company’s system, which relies on algorithms with potential flaws, raises concerns about both privacy and bias.

Nvidia releases robot toolbox to deepen support of AI-powered robotics in ROS
Posted by Gemechu Taye in category: robotics/AI
Nvidia announced today that Isaac, its developer toolbox for supporting AI-powered robotics, will deepen support of the Robot Operating System (ROS). The announcement is being made this morning at ROS World 2,021 a conference for developers, engineers, and hobbyists who work on ROS, a popular open-source framework that helps developers build and reuse code used for robotics applications.
Nvidia, which is trying to assert its lead as a supplier of processors for AI applications, announced a host of “performance perception” technologies that would be part of what it will now call Isaac ROS. This includes computer vision and AI/ML functionality in ROS-based applications to support things like autonomous robots.

Dinosaurs may have lived in social herds as early as 193 million years ago
Posted by Gemechu Taye in category: futurism
Fossils indicate a communal nesting ground and adults who foraged and took care of the young as a herd, scientists say.
To borrow a line from the movie “Jurassic Park:” Dinosaurs do move in herds. And a new study shows that the prehistoric creatures lived in herds much earlier than previously thought.
