Today’s infrared lasers are only powerful enough to disable aerial targets, but scientists now have the keys to building high-powered laser weaponry that can ‘melt’ distant targets.

I used GPT-3 and a Synthesia avatar. All answers are by GPT-3 (except the brief joke at the end).
Scientists have discovered a new class of materials, carbon nitrides, which could rival diamonds in hardness. This discovery, the result of international collaboration and decades of research, opens up possibilities for various industrial applications due to their durability and other properties like photoluminescence and high energy density. Funded by international grants and published in Advanced Materials, this breakthrough marks a significant advancement in material science.
Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says.
Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials – known as carbon nitrides – were tougher than cubic boron nitride, the second hardest material after diamond.
Shirriff’s blog goes into a deep dive with a look inside the HP PHI chip, its construction, and die. He even examines its logic gates, first-in-first-out buffers (FIFOs), and address decoder. Please check out the blog for all these finer details and more.
In conclusion, the computer historian echoes our initial thoughts that this silicon-on-sapphire IC is “interesting as an example of a ‘technology of the future’ that didn’t quite pan out.”
Shirriff also contrasts late 70s era processors built on silicon-on-sapphire vs regular silicon in terms of energy consumption and clock speeds. Would you be surprised to hear that silicon-on-sapphire ICs were far superior using these metrics? Things might have panned out differently if these transparent ICs had been mass-produced at better yields and lower manufacturing costs. A frightening statistic highlighted by Shirriff is that HP’s silicon-on-sapphire yields were a mere 9%.
The world works at different levels — fundamental physics, physics, chemistry, biology, psychology, sociology — with each level having its own rules and regularities. Here’s the deep question: Ultimately, can what happens at a higher level be explained entirely in terms of what happens at a lower level? If the answer is ‘No’, if complete explanatory reduction fails, then what else could be going on?\

New findings published in Molecular Cell provide details about the hidden organization of the cytoplasm—the soup of liquid, organelles, proteins, and other molecules inside a cell. The research shows it makes a big difference where in that cellular broth, messenger RNA (mRNA) gets translated into proteins.
“You know the old real estate saying, ‘location, location, location.’ It turns out it applies to how proteins get made inside of cells, too,” says Dr. Mayr, a molecular and cell biologist at the Sloan Kettering Institute, a hub for basic and translational research within MSK. “If it’s translated over here, you get twice as much protein as if it’s translated over there.”
This first-of-its-kind study highlights the degree to which the cytoplasm is “beautifully organized” rather than being just a big jumble of stuff, she says.
A new study found that while exercise is important to living a long life, following other healthy lifestyle habits may have an even greater impact.
This week at Starbase Booster 10 joins Ship 28 at the launch site to begin its testing on the orbital launch mount, Ship 28 performs a static fire test, and SpaceX shows off its holiday spirit, while over at Cape Canaveral, Starlink launch and recovery operations continue as several tanks and a prefabricated tower section are shipped out to Brownsville.\
