Gao Jifan said he sees solar dropping to a third or less of current costs by the middle of the century.
Ron FriedmanThink outside the box. Most people don’t need a car for the sake of having a car.
Most people need a comfortable, quick and cheap way of going from A to B. So, Robotaxi could be the ideal solution for most people most of the time.… See more.
Jerry AndersonProbably not, because new batteries that contain other elements, I think they are saying Sulfur-Lithium batteries are more efficient last longer, and don’t require recharging as often… There are bound to be other breakthroughs.

At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology. For the phenomenon to occur for a given substance, it must first go through a stage called nucleation, during which the molecules organize themselves and create the optimal conditions for the formation of crystals. While it has been difficult to observe pre-nucleation dynamics, this key process has now been revealed by the work of a research team from the University of Geneva (UNIGE). The scientists have succeeded in visualizing this process spectroscopically in real time and on a micrometric scale, paving the way to the design of safer and more stable active substances. These results can be found in the Proceedings of the National Academy of Sciences (PNAS).

This week, the two Dutch researchers took home $90,000 and a new Pwn2Own championship trophy by targeting the software that helps run the world’s critical infrastructure.
They say it was their easiest challenge yet.

Walter LynsdaleI’m all for people making billions through technical advancement (teslas, space X rockets, the dojo chip are all pretty cool), but he comes out with a fair amount of double speak:

NASA has picked SpaceX, Amazon and four other American companies to develop the next generation of near-Earth space communication services meant to support its future missions. The agency started looking for partners under the Communication Services Project (CSP) in mid-2021, explaining that the use of commercially provided SATCOM will reduce costs and allow it to focus its efforts on deep space exploration and science missions.
“Adopting commercial SATCOM capabilities will empower missions to leverage private sector investment that far exceeds what government can do,” NASA wrote in the official project page. By using technology developed by commercial companies, the agency will have continued access to any innovation they incorporate into the system. At the moment, NASA relies on its Tracking and Data Relay Satellite (TDRS) system for near-Earth space communications. Many of its satellites were launched in the 80’s and 90’s, though, and it’s set to be decommissioned in the coming years.
The funded agreements under NASA’s Communication Services Project has a combined value of $278.5 million, with SpaceX getting the highest cut. NASA expects the companies to match and exceed its contribution during the five-year development period. SpaceX, which proposed a “commercial optical low-Earth orbiting relay network for high-rate SATCOM services,” has been awarded $69.95 million. Amazon’s Project Kuiper is getting the second-highest cut and has been awarded $67 million, while Viasat Incorporated has been awarded $53.3 million. The other three awardees are Telesat US Services ($30.65 million), SES Government Solutions ($28.96 million) and Inmarsat Government Inc. ($28.6 million).
Researchers in Beijing have set a new quantum secure direct communication (QSDC) world record of 102.2 km (64 miles), smashing the previous mark of 18 km (11 miles), The Eurasian Times reported. Transmission speeds were extremely slow at 0.54 bits per second, but still good enough for text message and phone call encryption over a distance of 30 km (19 miles), wrote research lead Long Guilu in Nature. The work could eventually lead to hack-proof communication, as any eavesdropping attempt on a quantum line can be instantly detected.
QSDC uses the principal of entanglement to secure networks. Quantum physics dictates that entangled particles are linked, so that if you change the property of one by measuring it, the other will instantly change, too — effectively making hacking impossible. In theory, the particles stay linked even if they’re light-years apart, so such systems should work over great distances.
The same research team set the previous fiber record, and devised a “novel design of physical system with a new protocol” to achieve the longer distance. They simplified it by eliminating the “complicated active compensation subsystem” used in the previous model. “This enables an ultra-low quantum bit error rate (QBER) and the long-term stability against environmental noises.”
For centuries, mathematicians have tried to prove that Euler’s fluid equations can produce nonsensical answers. A new approach to machine learning has researchers betting that “blowup” is near.
