Synchronized laser pulses (red and blue) generate a burst of real and virtual charge carriers in graphene that are absorbed by gold metal to produce a net current. “We clarified the role of virtual and real charge carriers in laser-induced currents, and that opened the way to the creation of ultrafast logic gates,” says Ignacio Franco, associate professor of chemistry and physics at the University of Rochester.

We no longer have a supply problem with vaccines. The only question left is, are you limited by demand or by logistics. In less vaccinated countries, there isn't much demand. In Nigeria, Covid would be, like, the 15th-largest cause of death—you've got HIV, TB, malaria, diarrhea. So when you say to them, “Hey, number 15,” they're like, “Well, what about number one, number two, number three, number four—show me some dead bodies!”I love these articles that say, “Hey, if these countries don't vaccinate themselves, they're…

The WHO estimates that the Covid-19 pandemic has killed almost 15 million people worldwide — not just from the virus, but as an indirect result of the crisis, such as being unable to get other kinds of medical care because hospital systems were overburdened. But it didn’t have to be so catastrophic. Experts say its impacts were exacerbated by a number of factors: The world was ill-prepared for a pandemic, many countries were slow to develop and provide access to Covid-19 tests, and economic inequality made everything…

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser pulses, the new logic gates are a million times faster than those in existing computers, demonstrating the viability of “lightwave electronics.”Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or…

Bill Gates said that he isn’t sure of Elon Musk’s motives in buying Twitter Inc. TWTR 0.39% and that social media must play a role in curbing the spread of misinformation.“He actually could make it worse,” Mr. Gates said of Mr. Musk’s potential impact on the platform, speaking Wednesday at The Wall Street Journal’s CEO Council Summit. But, he said, “That’s not his track record.” “How does he feel about…
