Scientists Are Now One Step Closer to a Nuclear Clock

From Popular Mechanics

Scientists have a new precise measurement they say could help them finally make a nuclear clock, rather than a simply atomic one.

☢️ You love nuclear. So do we. Let’s nerd out over nuclear together.

Physicists from Gutenberg Universitaet Mainz (JGU) and other German scientists used an extremely tiny instrument—a magnetic microcalorimeter named maXs30—to measure movement within the nucleus of the isotope thorium-229. The scientists super-cooled the detector to minus 273 degrees Celsius to measure the “miniscule temperature rise that occurs when a gamma-ray is absorbed,” according to the JGU press release.

Thorium-229 is special among isotopes because of the extremely low energy of its lowest excited state, meaning it’s the best candidate for a measurable standard that can be used to make a practical clock. This isn’t something you’ll put on your nightstand, or even something that will likely be used inside your local university’s advanced

  • Foxconn, Apple’s main iPhone assembler, has ramped up iPhone production at its factory in Zhengzhou, China ahead of the expected iPhone 12 launch next month.
  • The factory is working 24 hours per day, offering worker bonuses, and canceling holidays to focus on iPhone production, according to a report from the South China Morning Post.
  • Zhengzhou is often referred to “iPhone City” by locals because of the factory’s massive presence in the city.
  • Apple typically unveils its new iPhones in September, but the company is instead expected to reveal its latest lineup in October after facing delays because of the coronavirus pandemic.
