Polestar, the Volvo offshoot EV company, has made a smartphone. It's called, predictably, the Polestar Phone, and it's only available in China. There have been a lot of car-brand smartphones out there (it's often Lamborghini), but usually, these are licensing deals that the car company ignores. Polestar seems to be proud of this phone, though, making it a bit more involved than the usual car-brand licensing deal. Just look at the new navigation drawer on the polestar.cn site, which has four main items: "Polestar 2", "Polestar 3", "Polestar 4" and now "Polestar Phone."

Why would a niche EV brand make a phone? Maybe all that work on the Android Automotive OS made Polestar's engineers really enthusiastic about Android device development. The website, through machine translation, promises the phone was "jointly designed by the Polestar global design team and the Xingji Meizu team in Gothenburg, Sweden, and is decorated with Swedish gold details that symbolize high performance." "Decorated" is probably the best way you could describe Polestar's contributions to this phone since it seems to be a bog standard Meizu 21 Pro with some Polestar branding. It does look beautiful, with a no-nonsense minimal rectangular design and all-screen front, but the same can be said for the Meizu phone this is based on.

So, how exactly is the Polestar Phone related to a Polestar car? Well, both run Android and have all-electric power systems. The phone has a slightly smaller battery than the EV, at only 5,050 mAh (that's something like 18 Wh) compared to the 100 kWh battery of something like a Polestar 4. The car also has the phone beat on-screen size, with the phone packing a pocketable 120 Hz 6.79-inch, 3192×1368 OLED, and the Polestars all sporting big tablet screens.

Gamma rays are a broad category of high-energy photons, including everything with more energy than an X-ray. While they are often created by processes like radioactive decay, few astronomical events produce them in sufficient quantities that they can be detected when the radiation originates in another galaxy.

That said, the list is larger than one, which means detecting gamma rays doesn't mean we know what event produced them. At lower energies, they can be produced in the areas around black holes and by neutron stars. Supernovae can also produce a sudden burst of gamma rays, as can the merger of compact objects like neutron stars.

And then there are magnetars. These are neutron stars that, at least temporarily, have extreme magnetic fields—over 10¹² times stronger than the Sun's magnetic field. Magnetars can experience flares and even giant flares where they send out copious amounts of energy, including gamma rays. These can be difficult to distinguish from gamma-ray bursts generated by the merger of compact objects, so the only confirmed magnetar giant bursts have happened in our own galaxy or its satellites. Until now, apparently.

Hackers backed by a powerful nation-state have been exploiting two zero-day vulnerabilities in Cisco firewalls in a five-month-long campaign that breaks into government networks around the world, researchers reported Wednesday.

The attacks against Cisco’s Adaptive Security Appliances firewalls are the latest in a rash of network compromises that target firewalls, VPNs, and network-perimeter devices, which are designed to provide a moated gate of sorts that keeps remote hackers out. Over the past 18 months, threat actors—mainly backed by the Chinese government—have turned this security paradigm on its head in attacks that exploit previously unknown vulnerabilities in security appliances from the likes of Ivanti, Atlassian, Citrix, and Progress. These devices are ideal targets because they sit at the edge of a network, provide a direct pipeline to its most sensitive resources, and interact with virtually all incoming communications.

Cisco ASA likely one of several targets

On Wednesday, it was Cisco’s turn to warn that its ASA products have received such treatment. Since November, a previously unknown actor tracked as UAT4356 by Cisco and STORM-1849 by Microsoft has been exploiting two zero-days in attacks that go on to install two pieces of never-before-seen malware, researchers with Cisco’s Talos security team said. Notable traits in the attacks include:

On Friday, a federal judicial panel convened in Washington, DC, to discuss the challenges of policing AI-generated evidence in court trials, according to a Reuters report. The US Judicial Conference's Advisory Committee on Evidence Rules, an eight-member panel responsible for drafting evidence-related amendments to the Federal Rules of Evidence, heard from computer scientists and academics about the potential risks of AI being used to manipulate images and videos or create deepfakes that could disrupt a trial.

The meeting took place amid broader efforts by federal and state courts nationwide to address the rise of generative AI models (such as those that power OpenAI's ChatGPT or Stability AI's Stable Diffusion), which can be trained on large datasets with the aim of producing realistic text, images, audio, or videos.

In the published 358-page agenda for the meeting, the committee offers up this definition of a deepfake and the problems AI-generated media may pose in legal trials:

The US Chamber of Commerce and other business groups sued the Federal Trade Commission and FTC Chair Lina Khan today in an attempt to block a newly issued ban on noncompete clauses.

The lawsuit was filed in US District Court for the Eastern District of Texas. The US Chamber of Commerce was joined in the suit by Business Roundtable, the Texas Association of Business, and the Longview Chamber of Commerce. The suit seeks a court order that would vacate the rule in its entirety.

The lawsuit claimed that noncompete clauses "benefit employers and workers alike—the employer protects its workforce investments and sensitive information, and the worker benefits from increased training, access to more information, and an opportunity to bargain for higher pay."

"Early Access" was once a novel, quirky thing, giving a select set of Steam PC games a way to involve enthusiastic fans in pre-alpha-level play-testing and feedback. Now loads of games launch in various forms of Early Access, in a wide variety of readiness. It's been a boon for games like Baldur's Gate 3, which came a long way across years of Early Access.

Early Access, and the "Advanced Access" provided for complete games by major publishers for "Deluxe Editions" and the like, has also been a boon to freeloaders. Craven types could play a game for hours and hours, then demand a refund within the standard two hours of play, 14 days after the purchase window of the game's "official" release. Steam-maker Valve has noticed and, as of Tuesday night, updated its refund policy.

"Playtime acquired during the Advanced Access period will now count towards the Steam refund period," reads the update. In other words: Playtime is playtime now, so if you've played more than two hours of a game in any state, you don't get a refund. That closes at least one way that people could, with time-crunched effort, play and enjoy games for free in either Early or Advanced access.
