“It just really shocked me, because I came into this project thinking that these phones are really protecting user data well,” says Johns Hopkins cryptographer Matthew Green, who oversaw the research.

Dale was a US Air Force fighter pilot sitting in an F-117 Nighthawk stealth fighter—the black angular ones that look like a UFO—a jet that was considered by most people at the time to be pretty much invulnerable.

Such digital extortion attempts have been around for decades, but the Vastaamo situation was particularly egregious, because the stolen data, which went back roughly two years, included psychotherapy notes and other sensitive information about patients' mental health treatment.

There will be more news to come about the SolarWinds supply chain attack and possible other elements of the extensive campaign, but in the meantime officials, security practitioners, and researchers are all puzzling over questions of where to draw the line on global espionage and how to deter destructive and otherwise unacceptable hacking.

David Silver: The big step forward with MuZero is we don't tell it the dynamics of the environment; it has to figure that out for itself in a way that still lets it plan ahead and figure out what's going to be the most effective strategy.

In this case, that rocket will push on the top mass in whatever direction (and magnitude) it needs to keep the thing still so it can act like a pendulum.

If you aren't familiar with these numerical calculations (another name for computational physics), the basic idea is to take a problem and break it into many smaller and simpler problems.

The Air Force and Space Force had their own “move 37” moment last month during the first AI-enabled shoot-down of a cruise missile at blistering machine speeds.

In some way, the atoms on the surface of the wood block are interacting with the surface atoms on the table.That is to say, the frictional force pushes in a direction to try to prevent sliding.

It's still powerful though, with an Intel i7 chip, an Nvidia GeForce GTX 1660 graphics card, 18-gigabytes of RAM, a 256-gigabyte SSD, and a 15.6-inch Full HD 144-Hz display.

But public health requires the public’s consent: The technologies that will help us get past Covid-19 are only as valuable as the number of people who use them.

Mitchell says law enforcement agencies routinely use tools that trawl social media for posts on particular topics, and that they have been used, for example, against people protesting the killing of George Floyd by Minnesota police.“If you live in the United States and you’re exercising your rights to free speech and assembly to march and demonstrate, you might not realize that the entire time there’s a lot of data being vacuumed up and used against you,” Mitchell said.

It’s one of the largest global dark web takedowns to date: 179 arrests spread across six countries; 500 kilograms of drugs seized; $6.5 million in cash and cryptocurrency confiscated.

Like so many of the revelations about content that violates platform policies, the TPA posts were revealed not through the platforms’ own moderators, but through the intrepid reporting of journalists.

Photograph: GoogleAt the moment, Nearby Share is available for select Google Pixel and Samsung Galaxy phones, but Google says that because the feature is a part of Google Play Services, you do not need to wait for an over-the-air update from your manufacturer or carrier to get it.

Dyson’s 2013 calculation convinced many people that gravitational wave detectors were, at best, impractical probes for learning about quantum gravity.“There’s a kind of default consensus that it’s a waste of time to think about quantum effects and gravitational radiation,” said Frank Wilczek, a Nobel Prize-winning physicist at MIT who was a coauthor with Parikh on the new paper.

Despite recent successes with remote work, employers are reopening offices to some of their employees to encourage social bonding, reinforce culture, and increase business collaboration.If an office is the “glue”, and processes and systems don’t adapt for a remote workforce, remote team members will not feel included and will face constant communication barriers.

My office life resembled that of any full-time employee: I snacked on charcuterie boards and fresh ahi poke bowls, rejiggered my calendar to accommodate conflicting meetings, and cheered for employees on their work anniversaries (a peculiar Silicon Valley ritual that celebrates equity accruing).Unlike full-time employees, contract workers aren’t entitled to Airbnb’s premium health care, generous 401(k), unlimited paid vacation time, transportation coverage, and stock options.

DDOSecrets founder Emma Best tells WIRED that the hacked files came from Anonymous—or at least a source self-representing as part of that group, given that under Anonymous' loose, leaderless structure anyone can declare themselves a member."It's the largest published hack of American law enforcement agencies," Emma Best, cofounder of DDOSecrets, wrote in a series of text messages.

Crucially, to enable end-to-end encryption, free users will need to submit and verify an identifying piece of data, like a phone number.

"Free users for sure we don’t want to give that," Zoom CEO Eric Yuan said in a company earnings call on Tuesday referring to end-to-end encryption, "because we also want to work together with FBI, with local law enforcement in case some people use Zoom for a bad purpose.".

“The federal government doesn’t really keep track of a lot of this equipment that goes to local law enforcement agencies,” says Anna Gunderson, a political scientist at Louisiana State University who coauthored a 2019 study that examined the effects of the 1033 program on crime rates.

Faced with a task like calculating how three wispy quarks produce the hulking proton, QCD simply fails to produce a meaningful answer.“It’s tantalizing and frustrating,” said Mark Lancaster, a particle physicist based at the University of Manchester in the United Kingdom.

Our new program, Agility Prime, leverages unique Air Force assets—test ranges, safety certifications, and military missions capable of logging steady flight hours—to build confidence in the technology, attract investors, and hopefully expedite domestic commercialization.Flying cars aren’t the only commercial technology the military can help accelerate.

Now usually, a squirrel will jump off a bird feeder that starts to spin—but not the one in this viral video.But what is the force-paired object pushing on the squirrel?When you drop that apple, the gravitational force increases its speed as it falls, thus increasing its momentum.

has developed a platform that consists of off-the-shelf robot arms equipped with cameras, a special gripper, and plenty of computer power for figuring out how to grasp objects tossed into warehouse bins.

I mean, it’s a cool invention—the idea of the HoverGlide pack is to reduce the awkward bouncing and jolting you get with ordinary backpacks.After all, once you leave the ground, there is a gravitational force on both you and the pack.

The company has put a $50 million infusion towards building out features that make it not just secure, but accessible to normals .A Clever New App Makes Suing Robocallers a CinchThe good people at DoNotPay have previously automated the arduous processes of fighting parking tickets and canceling subscriptions.

That’s the premise behind this video of the supposed “first wireless bungee jump.” Let me be real clear: It’s a fake.As the cord stretches, it exerts an upward force on the jumper in the same direction that the ground would push.

“Once you go to space, you can throw your object, and it will be in free fall for a long time,” says physicist Aurélien Hees of the Paris Observatory, a member of the team.
