In 1952, a University of Chicago chemist named Stanley Miller and his adviser, Harold Urey, conducted a famous experiment. Their results, published the following year, provided the first evidence that the complex organic molecules necessary for the emergence of life (abiogenesis) could be formed using simpler inorganic precursors, essentially founding the field of prebiotic chemistry. Now a team of Spanish and Italian scientists has recreated that seminal experiment and discovered a contributing factor that Miller and Urey missed. According to a recent paper published in the journal Scientific Reports, minerals in the borosilicate glass used to make the tubes and flasks for the experiment speed up the rate at which organic molecules form.

In 1924 and 1929, respectively, Alexander Oparin and J.B.S. Haldane had hypothesized that the conditions on our primitive Earth would have favored the kind of chemical reactions that could synthesize complex organic molecules from simple inorganic precursors—sometimes known as the "primordial soup" hypothesis. Amino acids formed first, becoming the building blocks that, when combined, made more complex polymers.

Miller set up an apparatus to test that hypothesis by simulating what scientists at the time believed Earth's original atmosphere might have been. He sealed methane, ammonia, and hydrogen inside a sterile 5-liter borosilicate glass flask, connected to a second 500-ml flask half-filled with water. Then Miller heated the water, producing vapor, which in turn passed into the larger flask filled with chemicals, creating a mini-primordial atmosphere. There were also continuous electric sparks firing between two electrodes to simulate lighting. Then the "atmosphere" was cooled down, causing the vapor to condense back into water. The water trickled down into a trap at the bottom of the apparatus.

US Copyright Office Expands Jailbreaking Exemption to Roku and Apple TV

The US Copyright Office has published a list of new exemptions to the DMCA’s anti-circumvention rules. Several new freedoms were granted this round, including broader right to repair permissions. The right to jailbreak also expanded to include streaming TV devices such as Roku and Apple TV boxes, despite Hollywood fears that this will boost piracy.

From: TF, for the latest news on copyright battles, piracy and more.

Section 1201 of the DMCA prohibits the circumvention of copyright controls without permission.

This legal restriction prevents the general public from bypassing DRM protection on a wide variety of content and devices.

There are some important exceptions to this rule, however. This includes phone jailbreaking, which was declared legal in 2010. These provisions are renewed every three years after the Copyright Office hears various arguments from stakeholders and the general public.

Jailbeaking Video Streaming Devces

This triannual review also allows interested parties to come up with new proposals. In the most recent rulemaking process, for example, the Electronic Frontier Foundation (EFF) suggested an expansion of the current jailbreaking exemptions to include video streaming devices.

In previous years the Office already allowed the public to jailbreak smartphones, tablets, wearables, and smart TVs. According to the EFF, general video streaming devices such as Roku and Apple TV boxes should fit in the same category.

Jailbreaking these devices will enable the public to “exercise full control” over their hardware, EFF argued. That allows people to unlock valuable new features, such as adding a web browser and compatibility with other tools such as privacy-enhancing VPNs.

Copyright Holders Fear Widespread Piracy

This proposal received broad support from digital rights activists. However, major copyright industry groups including the RIAA, ESA, and Hollywood’s MPA, fiercely opposed the plan. They urged the Copyright Office not to grant the exemption as it would open the door to widespread piracy.

The groups fear that jailbreaking will result in widespread copyright infringement, as it allows the public to install piracy tools on these video devices as well.

“Access controls on these devices are designed to prevent unauthorized access to copyrighted works,” the copyright holders wrote. “Once circumvented, even for the ostensible purpose of first installing a lawful application, nothing prevents a user from later installing infringing applications or applications that enable infringement on these devices.”

Jailbreaking Exemption Approved

After reviewing the input from both sides, the Copyright Office recommended approving the new DMCA anti-circumvention exemption. According to the Office, the current limitations hinder fair use modifications of these devices.

“Proponents have satisfied their burden of showing that technological measures applied to video streaming devices and routers or other networking devices are having, or are likely to have, an adverse effect on noninfringing uses. The Register accordingly recommends adoption of exemptions authorizing the jailbreaking of both types of devices, with appropriate limitations.”

Copyright holder fears that the exemption will open the door to piracy apps is ungrounded. Similar comments were made in 2015 when the Smart-TV exemption was discussed, and the Copyright Office sees no reason to change its position.

“While opponents argue that the proposed exemption could lead to unauthorized access to copyrighted works and to unapproved apps, as in 2015, “[n]o actual evidence was submitted to illustrate the claim that jailbreaking . . . will make it easier to gain unauthorized access to copyrighted content’,” the Office notes.

Limitations Apply

The final exemption class does come with some limitations. People are only allowed to use jailbroken devices with “lawfully obtained software.” In addition, jailbreaking should not be carried out to “gain unauthorized access to other copyrighted works.”

This advice was adopted and the Librarian of Congress has now published the full list of new rights that go into effect today. The full streaming device section reads as follows:

Computer programs that enable smart televisions to execute lawfully obtained software applications, where circumvention is accomplished for the sole purpose of enabling interoperability of such applications with computer programs on the smart television, and is not accomplished for the purpose of gaining unauthorized access to other copyrighted works. For purposes of this paragraph (b)(10), “smart televisions” includes both internet-enabled televisions, as well as devices that are physically separate from a television and whose primary purpose is to run software applications that stream authorized video from the internet for display on a screen.

The Copyright Office specifically states that the new exemptions apply to Roku and Apple TV but hardware from other manufacturers with similar restrictions should fall into the same category. Jailbreaking was already quite common for these devices and now people are allowed to do this legally.

The final rule also includes other new exemptions, including broader rights to repair video game consoles. However, the proposal to allow museums and libraries to allow the public to access abandoned video games off-premises was rejected.

Facebook who? Zuckerberg announces rebranding as Meta

New name comes with company’s “new north star—to help bring the metaverse to life.”

As part of an Oculus Connect keynote presentation today, Facebook CEO Mark Zuckerberg rolled out the name "Meta" as a new corporate identity reflecting the company's "new north star—to help bring the metaverse to life."

The name, which Zuckerberg noted comes from the Greek word for "beyond," is "a new company brand to encompass everything that we do." That means the company will be "looking at and reporting on our business as two different segments, one for a family of apps and one for work on future platforms," he said.

The name Facebook, Zuckerberg said, "just doesn't encompass everything we do" anymore. While social media apps will "always" be a focus for Meta, it has been limiting to have a "brand that is so tightly linked to one product that it can't possibly represent everything we're doing today, let alone in the future," he said.

Climate change is shifting polar bears’ Arctic menu, research shows

Polar bears are eating different prey as climate change alters the Arctic.

The Arctic is warming three times faster than the rest of the world. Because of that warming, some organisms are adapting by shifting their natural stomping grounds, and the region is seeing some species move in as they follow the warmth north and stick around there for longer.

As such, the menu for polar bears is changing, according to a recently published paper. The research also suggests that studying fat tissue from polar bears—which can shed light on what prey they’ve been consuming—can be a useful tool in monitoring how species distribution in the Arctic is changing as temperatures increase and ice melts.

“The Arctic is changing. It is changing at a very rapid pace, especially in comparison to really any other region of the world. Temperatures are warming faster,” Melissa Galicia, a PhD candidate in York University’s department of biology and one of the authors of the paper, told Ars. “The ice is declining. Sea ice is becoming more fragmented. The water temperatures are warming. You’re getting an ecosystem that is changing rapidly, and all of the species within that ecosystem also need to adapt.”

Intel’s 12th-gen Alder Lake CPUs will try to make up for Rocket Lake’s stumbles

New desktop CPUs include DDR5 RAM support, PCI Express 5.0, and more cores.

Intel's 11th-generation desktop processors, codenamed Rocket Lake, didn't impress us much. They were Intel's sixth processor architecture based on some version of Intel's 14nm manufacturing process and the first not to use an iteration of the venerable Skylake core from 2015.

They did improve performance, usually, by backporting features from newer and faster processor architectures. But when you add features without improving the manufacturing process, you get exactly what Rocket Lake delivered: a processor that is a bit faster but also a lot hotter, with much higher power usage than either the 10th-generation Intel CPUs that preceded them or the AMD Ryzen 5000-series CPUs they compete against.

Now, Intel is attempting a course correction in the form of its 12th-generation Core CPUs, codenamed Alder Lake. The first six processors in the lineup are available for preorder now and will be available starting November 4th.

Like pixels to my ears: Asus headset uses mini LEDs to animate earcups

Because a gaming headset sits on your head (where you can't see it), its looks aren't all that important. But that hasn't stopped headset makers from blinging out their products. Besides, if you're on camera livestreaming or talking to your teammates, you might be looking to spice things up with pink cat ears or RGB-infused earcups. The Asus ROG Delta S Animate offers a new, pixel-powered twist to gamers who want to put on a show.

Asus has put its AniMe Matrix custom lighting design system on both of the Delta S Animate's earcups. Mini LEDs fill the space and light up to depict preset or customized effects selected via Asus' free Armoury Crate software. An Asus spokesperson told Ars Technica that the ROG Delta S Animate has over 100 mini LEDs per earcup. Until this week, the AniMe Matrix was only available on select Asus Zephyrus gaming laptops. Asus' decision to continue offering the feature in new PCs—and now in a new category—shows the company is seeing some interest in the concept.

Want ghosts flying across the earcup pixel by pixel before turning into a pumpkin? Why not?

You can hide the MacBook Pro notch with a virtual bezel (on a per-app basis)

Apple’s new MacBook Pro 14 and 16 are some of the most powerful laptops available, thanks to the new M1 Pro and M1 Max processors. But they also have a controversial design – while Apple shrunk the display bezels for its latest MacBook Pro laptops, the company also introduced a camera notch.

Not only does this introduce an obstruction to the top of the display, but it can also cause some applications not to function properly. So Apple has revealed a solution: you can effectively disable the notch by introducing a virtual bezel.

@Jatodaro

A new Apple Support document explains how to configures apps (on a per-app basis) to “appear below the camera area” on the latest MacBook Pro laptops:

  • Close the app.
  • Click the Finder icon in the Dock.
  • Click Applications in the Finder sidebar.
  • Select the app you want to configure.
  • Choose File > Get Info or press Command-I.
  • In the App Info window, check the box that says “scale to fit below built-in camera.”

Now when you run that application, a set of virtual black bars will appear at the top of the display to the left and right of the camera notch, allowing the top of the app to stop below the camera instead of surrounding the notch.

This means menus and other items won’t be covered by the notch.

Why do we need this workaround? Because Apple doesn’t seem to have another way to deal with apps with a lot of menus, some of which would otherwise be hidden behind the notch.

Under normal conditions, if you slide a mouse cursor across the top of the screen, it will continue sliding invisibly when it hits the notch until it comes out on the other side. That’s a good thing if you don’t want the cursor behaving in unexpected ways when you move it across the screen. But it can be a problem for applications that have interactive elements that would normally show up exactly where that notch is.

Quinn Nelson of Snazzy Labs recently demonstrated the issue with some applications featuring invisible menu items, while other apps seem to circumvent this by not allowing you to click in the notch at all… but with the side effect that there’s not enough room for all status notifications, so some of them just disappear.

So the good news is that it looks like Apple does offer a workaround, which seems to work as promised, according to a brief demo posted by Joseph Angelo Todaro:

But the bad news is that not only does this setting add black bars to the top of the screen, but it also adds them to the left and right sides, further reducing your effective screen real estate.

So we’re left to wonder, not for the first time, why Apple didn’t just include a slightly thicker top bezel or follow the lead of companies like Asus and Lenovo that have been using reverse notch-style displays on some notebooks for the past few years, combining slim top bezels with small bump-outs above the display to make room for a camera section.

For now, it looks like it will be up to app developers to ensure their apps are compatible with Apple’s new displays, notch and all. The company notes that after an app developer updates their software to work with the new screens, the “scale to fit below built-in camera” option will no longer appear in the App Info for that specific app.

Mario Party Superstars is the “Greatest Hits album” the series deserves

Review: Excellent mini-game selection and polish make for enjoyable, chaotic romp.

"Yeah, Waliuigi time!"

Enlarge / "Yeah, Waliuigi time!"

Since the Mario Party series launched in 1998 on the N64, it has played host to over 1,000 mini-games spread across 15 titles (depending on how you count). The question behind Mario Party Superstars on the Switch is whether you can find 100 of those mini-games that are actually good.

The answer is a resounding yes. By focusing on the best and most enduring mini-game design from over two decades, Superstars is probably the most consistently enjoyable game in the series' long run. But if you're not already on board with Mario Party's slow pace and heavy reliance on luck, there's nothing here that will change your mind.

Better to be lucky than to be good

Mario Party Superstars is a game dripping with nostalgia, from the music and sound effects to the menu screen drawn straight from the first game. The structure of the main game is completely unchanged as well. Four human or computer-controlled players take turns rolling a 10-sided die to move around a board, trying to pass spots where they can buy the stars needed to win the game. After everyone has rolled, all four players face off in a mini-game where they can earn coins that can be used to buy stars or items that can help them or hinder others.

Nintendo has made some strong choices for the five available classic boards, which come from the N64 editions of the game. The options offer a full range of complexity, from the basic "walk in a circle" of Yoshi's Tropical Island to the constantly branching paths of Woody Woods to the complicated day-night cycle of Horror Land. Series fans will get a kick out of seeing these classic boards fully upgraded for the HD era, too—Peach's birthday cake, in particular, is a mouth-watering visual splendor compared to the unappetizing low-res polygons of the N64 original.

Australia also wants Google to unbundle search from Android

The ACCC takes issue with Google being the default search engine on everything.

The Australian Competition and Consumer Commission (ACCC) is the latest government regulatory body to take issue with how Google does business. As Reuters reports, the ACCC wants Google to show a "choice screen" to Android users, allowing them to pick a default search engine other than Google Search. The commission also wants to limit Google's ability to pay Apple and other vendors or platforms to be their default search engine.

ACCC Chair Rod Sims explained the commission's reasoning in a statement:

We are concerned that Google's dominance and its ability to use its financial resources to fund arrangements to be the default search engine on many devices and other means through which consumers access search, such as browsers, is harming competition and consumers. Google pays billions of dollars each year for these placements, which illustrates how being the default search engine is extremely valuable to Google's business model.

Market research firm Kantar says Android has a 60 percent share of the smartphone market, while on iOS and macOS, Google pays Apple an estimated $15 billion per year to be the default search on Safari. Google also pays Mozilla $400 million per year to remain the default on Firefox. Google has a 94 percent share of the Australian search engine market.
