When Diamonds Are Dirt Cheap, Will They Still Dazzle?

Posted by in category: life extension

Circa 2014


As a seventh grader, I was lucky to land the job of ball boy for the Brooklyn Dodgers during their annual late-March exhibition games in Miami. The experience left me with fond memories — of Roy Campanella smoking a cigar as he stroked line drives in the batting cage, of a young Sandy Koufax throwing harder than seemed humanly possible and of an aging Jackie Robinson struggling to remain in the lineup.

Oddly, however, my most vivid memory is of the Dodgers’ longtime batboy as he sat in the locker room producing autographed baseballs. He’d twist his hand at odd angles as he scrawled replicas of the signatures of Duke Snider, Pee Wee Reese and other Dodger legends. To my untrained eye, the balls he inscribed were indistinguishable from those signed by the players themselves.

Death-Bringing ‘Brain Tsunamis’ Have Been Observed in Humans

Posted by in categories: biotech/medical, neuroscience

Back in 2018, researchers were able to study the moment brain death becomes irreversible in the human body for the first time, observing the phenomenon in several Do Not Resuscitate patients as they died in hospital.

For years, scientists have researched what happens to your brain when you die, but despite everything we’ve found out, progress has been stymied by an inability to easily monitor human death – since physicians are conventionally obliged to prevent death if they can, not monitor it as it takes hold.

What this means is most of our understanding of the processes involved in brain death come from animal experiments, strengthened with what we can glean from the accounts of resuscitated patients disclosing their near-death experiences.

On the Edge: New Magnetic Phenomenon Discovered With Industrial Potential

Posted by in categories: nanotechnology, particle physics

Working with the tiniest magnets, Hebrew University discovers a new magnetic phenomenon with industrial potential.

For physicists, exploring the realm of the very, very small is a wonderland. Totally new and unexpected phenomena are discovered in the nanoscale, where materials as thin as 100 atoms are explored. Here, nature ceases to behave in a way that is predictable by the macroscopic law of physics, unlike what goes on in the world around us or out in the cosmos.

Dr. Yonathan Anahory at Hebrew University of Jerusalem (HU)’s Racah Institute of Physics led the team of researchers, which included HU doctoral student Avia Noah. He spoke of his astonishment when looking at images of the magnetism generated by nano-magnets, “it was the first time we saw a magnet behaving this way,” as he described the images that revealed the phenomenon of “edge magnetism.”

Teslas are susceptible to hacking due to bluetooth locks, cybersecurity firm says

Posted by in categories: cybercrime/malcode, mobile phones, transportation

Teslas are among the most susceptible vehicles to be hacked due to their Bluetooth locks, cybersecurity firm NCC Group said. The cars can be remotely unlocked and controlled by hackers that can exploit a vulnerability in the Bluetooth system’s security, the group said.

NCC Group researcher Sultan Qasim Khan was shown in a video opening, then driving a Tesla using a small relay device attached to a laptop. The device bridged a large gap between the Tesla and the Tesla owner’s phone, Reuters said.

“This proves that any product relying on a trusted BLE connection is vulnerable to attacks even from the other side of the world,” NCC said in a statement. BLE means Bluetooth Low Energy, and is a technology utilized in vehicles and Bluetooth locks that will automatically unlock or unlatch when an authorized device is nearby. While it is a convenience feature, it is not immune to attacks, which was the point of NCC’s experiment.

SpaceX launches Starlink 4–15 mission, expands booster fleet

Posted by in categories: internet, robotics/AI, satellites

The reason the Falcon Heavy hasn’t flown in about 3 years is that the Falcon 9 ended up having about twice the capacity that was planned for and so the Falcon 9 took away many missions from the Falcon Heavy. (There will finally be some more Falcon Heavy missions later this year…)

Anyway, SpaceX has again increased the capacity of the Falcon 9. They have changed certain timings during flight like igniting the MVac engine a few seconds earlier than on other missions and are separating the fairing closer to stage separation to shed dead weight earlier in the flight.
