Bizarre, Metallic Star Spotted Hurtling Out of the Milky Way at 2 Million Miles an Hour

Posted by in category: cosmology

About 2,000 light-years away from Earth, there is a star catapulting toward the edge of the Milky Way. This particular star, known as LP 40–365, is one of a unique breed of fast-moving stars—remnant pieces of massive white dwarf stars—that have survived in chunks after a gigantic stellar explosion.

“This star is moving so fast that it’s almost certainly leaving the galaxy…[it’s] moving almost two million miles an hour,” says JJ Hermes, Boston University College of Arts & Sciences assistant professor of astronomy. But why is this flying object speeding out of the Milky Way? Because it’s a piece of shrapnel from a past explosion—a cosmic event known as a supernova—that’s still being propelled forward.

Scientists discover a “mind-blowing” link between gut health and age reversal

Researchers demonstrate in a mouse model that when older mice have the gut microbiota of younger mice, they display behavioral qualities of younger mice too.

‘Holy grail discovery’ in solid-state physics could usher in new technologies

Posted by in categories: computing, physics, transportation

This axion insulating state was realized, Bansil says, by combining certain metals and observing their magnetoelectric response. In this case, researchers used a solid state chip composed of manganese bismuth telluride, which were adhered together in two-dimensional layers, to measure the resulting electric and magnetic properties.

Researchers note that such a finding has implications for a range of technologies, including sensors, switches, computers, and memory storage devices, among many others. The “storage, transportation, and manipulation of magnetic data could become much faster, more robust, and energy-efficient” if scientists can integrate these new topological materials into future devices, the researchers write.

“It’s like discovering a new element,” Bansil says. “And we know there’s going to be all sorts of interesting applications for this.”

Bionic arms and blue-eyed bots: How Russia aims to nurture a tech hub in its Far East

Posted by in categories: cyborgs, robotics/AI, transhumanism

VLADIVOSTOK, Russia — To see Russia’s ambitions for its own version of Silicon Valley, head about 5,600 miles east of Moscow, snake through Vladivostok’s hills and then cross a bridge from the mainland to Russky Island. It’s here — a beachhead on the Pacific Rim — that the Kremlin hopes to create a hub for robotics and artificial intelligence innovation with the goal of boosting Russia’s ability to compete with the United States and Asia.


On Russia’s Pacific shores, the Kremlin is trying to build a beachhead among the Asian tech powers.

Artificial Intelligence may diagnose dementia in a day

With a single photo, SpaceX sent a not-so-subtle message to FAA regulators

Posted by in categories: engineering, finance, government, space travel

And ArsTechnica seems to be totally missing the point as “delaying” Starship for SOUND AND PRACTICAL SAFETY AND ENVIRONMENTAL QUESTIONS is not ‘delaying’ progress and one needs to simply ask why SpaceX “engineers” can’t up their game enough to actually answer or address those legitimate questions? The answer is rather simple, they probably CAN but the person “in charge” has no with to, incentive to, or will to do so because he sees anyone that questions him as ‘unreasonable opposition’ rather than legitimate concern. Starship could crash and burn on the orbital flight and it would not make a difference at all to the ‘world’ in general. We can and have recovered from worse numerous times while advancing technology and transportation. The FACT that Musk, (and his many rapid fans) somehow “assume” that he and only he can ‘advance’ space access are very much proof that this is not about engineering, ability or purpose but strictly about ego.


To the FAA, Musk seemed to be saying, federal regulators must do their part to ensure the future arrives on schedule. Just as the 20th-century skyscrapers marked the beginning of a new era and eventually launched America into a prosperous future of finance, communication, marketing, and more, the 21st century now beckons.

The skyscraper age will soon give way to the space age.

How artificial intelligence could find dementia with a single brain scan

“If we intervene early, the treatments can kick in early and slow down the progression of the disease and at the same time avoid more damage,” Prof Zoe Kourtzi of Cambridge University said.

A 3D printed mechanical bioreactor for investigating mechanobiology and soft tissue mechanics

Posted by in category: biotech/medical

Circa 2018


Mechanical loading is an important cue for directing stem cell fate and engineered tissue formation in vitro. Stem cells cultured on 2-dimensional (D) substrates and in 3D scaffolds have been shown to differentiate toward bone, tendon, cartilage, ligament, and skeletal muscle lineages depending on their exposure to mechanical stimuli. To apply this mechanical stimulus in vitro, mechanical bioreactors are needed. However, current bioreactor systems are challenged by their high cost, limited ability for customization, and lack of force measurement capabilities. We demonstrate the use of 3-dimensional printing (3DP) technology to design and fabricate a low-cost custom bioreactor system that can be used to apply controlled mechanical stimuli to cells in culture and measure the mechanical properties of small soft tissues. The results of our in vitro studies and mechanical evaluations show that 3DP technology is feasible as a platform for developing a low-cost, customizable, and multifunctional mechanical bioreactor system.

• 3DP technology was used to print a multifunctional bioreactor system/tensile load frame for a fraction of the cost of commercial systems.
