Placing both AI and quantum technologies in a single office makes sense, says Steven Girvin, a quantum engineer at Yale University, as AI has emerged as a powerful tool for developing quantum computers. The office’s effectiveness will depend on coordinating myriad strains of research, he says. β€œIt’s nice to have one box on the org chart that sees the big picture of all the quantum investments,” he says. β€œBut whoever does that work has to spend all their time then making connections to all the other types of science that quantum needs.”

Machine learning is a useful tool for plenty of scientific areas. The reason 'AI' is getting grouped with quantum computing specificallyβ€”at companies like Google and now at DOEβ€”is because of branding and wishcasting.

Man unexpectedly cured of HIV after stem cell transplant A handful of people with HIV have been cured after receiving HIV-resistant stem cells – but a man who received non-resistant stem cells is also now HIV-free

A man has become the seventh person to be free of HIV after receiving a stem cell transplant to treat blood cancer. Crucially, he received stem cells that were not resistant to the virus, prompting scientists to rethink what's necessary for an HIV cure.

Closing Central Madrid To Cars Resulted In 9.5% Boost To Retail Spending, Finds Bank Analysis City of Madrid significantly boosted the takings of its shops and restaurants last Christmas by banning cars from the CBD, finds an analysis by Spain's second largest bank.

Keep this in mind when people claim cars mean business β€” closing Central #Madrid to cars over holidays resulted in a 9.5% boost in retail spending on its main shopping street: STUDY.

There was also a 71% drop in air pollution.

Why quasicrystals shouldn’t exist but are turning up in strange places Matter with β€œforbidden” symmetries was once thought to be confined to lab experiments, but is now being found in some of the world’s most extreme environments

Just edited this fantastic feature by @elisecutts.bsky.social: quasicrystals are turning up in meteorites, lightning strikes and even the aftermath of the Trinity test βš›οΈ

Beshear: Let me be clear. The president has both the funding and the authority to fund snap during a shutdown. In fact, every other president in every other shutdown has done so. People going hungry in this instance is a choice that this president has made.

I was at a drone metal show when the NYC election was called and briefly felt like I'd left my body. Mamdani is my age, another immigrant, someone who actually likes New York, a person that feels familiar and attuned to the greatness + promise of our city. Folks turning out for him is so hopeful!

The biggest difference by far watching the various campaigns as a New Yorker and all of the messaging we were targeted with I think is an important takeaway for the whole country:

Cuomo’s entire message was threats and fear and cynicism.

Mamdani’s entire message was lightness and joy and hope.
