The future of data storage might be frozen

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.

Biden: George Floyd's last words are "a wake-up call for our nation"

Joe Biden will call George Floyd’s dying words “a wake-up call for our nation,” and criticize President Trump’s decision to unleash tear gas on peaceful protesters outside the White House, in a civil rights speech from Philadelphia on Tuesday.

Why it matters: Biden in the address will seek to draw a sharp contrast between himself and Trump, whose first remarks addressing nationwide unrest Monday highlighted law and order, extreme demonstrations of militarized “strength” and other blustery threats.

The alarm over climate financial risk gets louder because of coronavirus

The COVID-19 pandemic underscores why market regulators, companies and investors should do a better job planning for climate risks to the financial system, a pair of reports finds.

Driving the news: The International Monetary Fund said projected increases in the frequency and severity of natural disasters are a potential threat that investors probably aren't weighing enough.

Facebook's first major public worker walkout

Disgruntled Facebook employees, upset for days over the company's decision not to take down what they saw as calls for violence from President Trump, made their grievances public on Monday, with reportedly hundreds of workers staging a virtual walkout.

Why it matters: Facebook staffers have pushed back against controversial management choices in the past, but they've never before made public their dissent en masse. The protest suggests that the company — already battered by privacy scandals and political tensions — could be beginning to lose at least some of its workforce's trust.
