Researchers at the University of Manchester in the UK have shown that by controlling the magnetic properties of individual molecules, it could be possible to create hard drives that can store 30+ terabits of data per square centimeter, New Scientist reports.

  • Because the molecules are unstable, they have to be frozen to -213° Celsius. With those temperature requirements, this won't work for amping up your cell phone storage.
  • Hard drives on desktops are divvied up into small magnetized areas that encode data in the direction of molecules' magnetic fields. Until now, this approach has limited how small a hard drive can be because single molecules can't remember their magnetic direction. The researchers were able to do get a molecule to do that at -213°C.
  • What's next: They want to make it work at -196°Celsius so it can be used in data centers cooled with liquid nitrogen. Another possibility? Space-based data centers operating at a cool -270°C.

Hurricane Zeta is "battering southeastern Louisiana and southern Mississippi with life-threatening storm surge, high winds, and heavy rain," per the National Hurricane Center.

What's happening: The hurricane was producing maximum sustained winds of nearly 110 mph and stronger gusts after making landfall on the southeastern coast of Louisiana as a Category 2 storm earlier Wednesday. By nightfall, Zeta had sustained winds of 80 mph with a wind gust of 104 mph.

The Supreme Court on Wednesday rejected a request by the Trump campaign and other Republicans to shorten North Carolina's deadline for mail-in ballots from nine to three days.

The big picture: This is the latest of a series of decisions over mail-in ballot deadlines in various states.
