'Squeezed' light might produce breakthroughs in nano-sized electronics

It's one thing to produce nanoscale devices, but it's another to study and improve on them — they're so small they can't reflect enough light to get a good look. A breakthrough might make that possible, however. UC Riverside researchers have built technology that squeezes tungsten lamp light into a 6-nanometer spot at the end of a silver nanowire. That lets scientists produce color imaging at an "unprecedented" level, rather than having to settle for molecular vibrations. The developers modified an existing "superfocusing" tool (already used to measure vibrations) to detect signals across the entire visible spectrum. Light travels in a flashlight-like conical path. When the nanowire's tip passes over an object, the system records that item's influence on the beam shape and color (including through a spectrometer). With two pieces of specrtra for every 6nm pixel, the team can create color photos of carbon nanotubes that would otherwise appear...

The Morning After: Meta gives up on fact checking for Facebook and Instagram

Meta CEO Mark Zuckerberg announced yesterday that the company is swinging away from its efforts to corral its content. Meta is suspending its fact-checking program to move to an X-style Community Notes model on Facebook, Instagram and Threads. We go into detail on the changes Meta promised, but is the company attempting to court the new Trump presidency? Well, alongside donating to Donald Trump’s inauguration fund, replacing policy chief Nick Clegg with a former George W. Bush aide and even adding Trump’s buddy (and UFC CEO) Dana White to its board… yeah. Probably. Meta blocked Trump from using his accounts on its platforms for years after he stoked the flames of the attempted coup of January 6, 2021. At the time, Zuckerberg said, “His decision to use his platform to condone rather than condemn the actions of his supporters at the Capitol building has rightly disturbed people in the US and around the world.” But who cares about that when you could get some sweet favor with the...
