AI learns physics to optimize particle accelerator performance
Posted by Dan Kummer in categories: biotech/medical, finance, information science, robotics/AI
Machine learning, a form of artificial intelligence, vastly speeds up computational tasks and enables new technology in areas as broad as speech and image recognition, self-driving cars, stock market trading and medical diagnosis.
Before going to work on a given task, machine learning algorithms typically need to be trained on pre-existing data so they can learn to make fast and accurate predictions about future scenarios on their own. But what if the job is a completely new one, with no data available for training?
Now, researchers at the Department of Energy’s SLAC National Accelerator Laboratory have demonstrated that they can use machine learning to optimize the performance of particle accelerators by teaching the algorithms the basic physics principles behind accelerator operations—no prior data needed.

3D printed nanomaterial could replace kevlar and steel for bulletproof armor
Posted by Dan Kummer in categories: 3D printing, nanotechnology
The Institute for Soldier Nanotechnologies (ISN), made up of the MIT, Caltech, ETH Zurich and the US Army Research Lab, has used 3D printing technology at the nanoscale to form a material that is reportedly more effective at stopping a projectile than Kevlar or steel.
Thinner than a single human hair, the material is made from tiny carbon struts that form interconnected tetrakaidecahedrons – structures with 14 faces – that are fabricated via two-photon lithography.
According to the team, the nano-architected material could potentially replace kevlar for a wide array of bulletproof protective gear used by the armed forces.

The U.S. is considering a radical rethinking of the dollar for today’s digital world
Posted by Shane Hinshaw in categories: cryptocurrencies, finance
Fed Chair Jerome Powell and his colleagues are moving ahead cautiously and methodically.
The Federal Reserve Bank of Boston is also expected to release the results of its research into the technological challenges associated with implementing a CBDC in the U.S.
It would take five-to-ten years to introduce a digital currency in the U.S., several experts say, but they argue policymakers can’t sit idly by.

North Korea Claims Successfully Testing a New Hypersonic Gliding Warhead
Posted by Gemechu Taye in categories: energy, existential risks, military
These missiles are too fast to detect. Hypersonic weapons technology is at the heart of a new arms race. Currently, the US, China, and Russia are all competing to develop the most effective long-range hypersonic missiles. A recent report revealed that North Korea has also successfully tested a hypersonic missile on January 5, 2022, the country’s second reported test of a hypersonic missile.
North Korea has also referred to verifying the “fuel ampoule system” during this deployment which means that the liquid fuel used by the missile was sealed at production. This allows for rapid deployment even after the missile has been stored for long periods of time, while also reducing its vulnerability to pre-emptive strikes.
We have now seen what North Korea can do in quite imaginative ways.
