Opera’s crypto browser is now available on iOS

Opera launched its dedicated “Crypto Browser” into beta back in January, promising to make Web3 as accessible as any Web2 website. The company released the browser for Windows, Mac and Android users back then, but the version for iOS devices still wasn’t ready for rollout. Now, Opera has announced that the Crypto Browser for iPhones and iPads is out and available for download from its website.

The browser comes with a built-in non-custodial crypto wallet that supports the Ethereum, Bitcoin and other blockchain ecosystems. It will allow users to buy crypto coins with fiat currency and to trade any supported token without needing to install extensions. In addition, the browser will give users access to Web3-based NFTs and decentralized apps, including 7,000 services based on the Polygon ecosystem. 

One of the browser’s other features is a Crypto Corner start page, where users can get live information and updates on cryptocurrency, such as the latest prices and events, airdrops and relevant podcasts. Opera says it designed the browser for both veteran crypto users, as well as newbies who still need help navigating cryptocurrencies and Web3. 

Jorgen Arnesen, EVP Mobile at Opera, said in a statement:

“The interest in Web3 is continuing to grow. The Opera Crypto Browser Project was built to simplify the Web3 user experience that has often been bewildering for mainstream users. Opera believes Web3 has to be easy to use in order to reach its full potential and a mass adoption.”

Opera didn’t say whether the iOS browser supports the more energy-efficient Etherium Layer 2 standard. It did launch Layer 2 support for the Android version back in February, however, which the company claims makes it the first mobile browser to have the feature. 

DC Attorney General asks court to reconsider Amazon antitrust lawsuit

DC Attorney General Karl Racine has filed a motion (PDF) asking the court to reconsider its decision to dismiss the antitrust lawsuit he filed against Amazon in 2021. In the original lawsuit, Racine accused the e-commerce giant of “illegally abusing and maintaining its monopoly power by controlling prices across the online retail market.” Third-party sellers that use Amazon’s Marketplace have to abide by the company’s agreement, which includes a fair pricing policy. If they sell their goods for lower prices elsewhere, Amazon could remove their items’ buy box, suspend their shipment option and even terminate their selling privileges for “serious or repeated cases.”

The company stopped telling sellers back in 2019 in the midst of antitrust scrutiny that they couldn’t sell their products for cheaper prices elsewhere. However, the company later added back a clause under its fair pricing policy that’s nearly identical. Racine argued that since sellers price their goods with Amazon’s cut in mind, the policy artificially raises prices even on sellers’ own websites and on competing e-commerce platforms. 

Amazon told us when Racine first filed the lawsuit that the Attorney General had it “exactly backwards.” The spokesperson said: “Amazon takes pride in the fact that we offer low prices across the broadest selection, and like any store we reserve the right not to highlight offers to customers that are not priced competitively. The relief the AG seeks would force Amazon to feature higher prices to customers, oddly going against core objectives of antitrust law.” The Superior Court of the District of Columbia sided with Amazon and threw out Racine’s complaint back in March. 

Now, the DC AG wants another chance at proving that Amazon violated antitrust laws. His office’s amended complaint includes additional details about how the company’s policy violates DC code, mostly focusing on how it “causes prices to District residents to be higher than they otherwise would be” and how it inhibits sellers from competing with Amazon’s own products. 

Racine said in a statement about the motion he filed:

“We’re asking the court to reconsider its decision to dismiss our Amazon case because the antitrust laws and facts are on our side and we are determined to continue standing up for DC consumers. Amazon illegally uses its market power to prevent sellers from lowering their prices on other platforms — including their own. This results in higher prices for DC consumers.”

Apple has reportedly started testing nine Mac models with M2 chips

Apple may soon release a new set of Mac computers powered by the next generation of its homegrown chip. According to Bloomberg’s Mark Gurman, the tech giant has started the widespread testing of at least nine Mac models with four different M2 chips, which suggests that Apple is gearing up to launch them. While it’s not supposed to be public knowledge, Apple has been testing the machines using third-party apps from the App Store, and those applications’ developer logs give us an idea of what to expect from the company’s upcoming batch of computers.

One of the devices reportedly being tested is a MacBook Air with an M2 chip) that has eight CPU cores and 10 cores for graphics, up from eight in the current model. Previous reports suggest that the next MacBook Air will feature a major redesign, which may include a thinner frame, more ports and MagSafe charging. Apple is also apparently testing a couple of Mac minis powered by an M2 and an M2 Pro chip, as well as an entry-level M2 MacBook Pro with the same specifications as the aforementioned MacBook Air. 

Apple just released its 14- and 16-inch MacBook Pros in October, but Gurman says the company has started testing new 14-inch and 16-inch laptops with 64GB of memory powered by M2 Pro and M2 Max chips. The M2 Max apparently has 12 CPU cores and 38 graphics cores, up from 10 and 32 in the current models. Finally, there’s the new Mac Pro that will reportedly be powered by the M1 Ultra’s successor. The M1 Ultra, which was just recently launched, is Apple’s most robust chip yet and currently powers the Mac Studio. Gurman warns that there are no guarantees that the company will release all the models it’s currently testing. That said, he believes the new MacBook Air and Mac mini, as well as the new entry-level MacBook Pro will be released sometime this year. 

MIT engineers built a robot for emergency stroke surgeries

Remote robotic-assisted surgery is far from new, with various educational and research institutions developing machines doctors can control from other locations over the years. There hasn’t been a lot of movement on that front when it comes to endovascular treatments for stroke patients, which is why a team of MIT engineers has been developing a telerobotic system surgeons can use over the past few years. The team, which has published its paper in Science Robotics, has now presented a robotic arm that doctors can control remotely using a modified joystick to treat stroke patients.

That arm has a magnet attached to its wrist, and surgeons can adjust its orientation to guide a magnetic wire through the patient’s arteries and vessels in order to remove blood clots in their brain. Similar to in-person procedures, surgeons will have to rely on live imaging to get to the blood clot, except the machine will allow them to treat patients not physically in the room with them. 

There’s a critical window of time after a stroke’s onset during which endovascular treatment should be administered to save a patient’s life or to preserve their brain function. Problem is, the procedure is quite complex and takes years to master. It involves guiding a thin wire through vessels and arteries without damaging any of them, after all. Neurosurgeons trained in the procedure are usually found in major hospitals, and patients in remote locations that have to be transported to these larger centers might miss that critical time window. With this machine, surgeons can be anywhere and still perform the procedure. Another upside? It minimizes the doctos’ exposure to radiation from X-ray imaging.

During their tests, the MIT engineers only had to train a group of neurosurgeons for an hour to use the machine. By the end of that hour, the surgeons were able to successfully use the machine to remove the fake blood clots in a transparent model with life-size vessels replicating the complex arteries of the brain.

MIT professor and team member Xuanhe Zhao said:

“We imagine, instead of transporting a patient from a rural area to a large city, they could go to a local hospital where nurses could set up this system. A neurosurgeon at a major medical center could watch live imaging of the patient and use the robot to operate in that golden hour. That’s our future dream.”

Wikipedia editors vote to block cryptocurrency donations

Wikipedia editors have voted in favor of dropping cryptocurrency from the Wikimedia Foundation’s donation options. As Ars Technica reports, an editor for the online encyclopedia called GorillaWarfare wrote a proposal for the foundation to stop accepting cryptocurrencies, as they are “extremely risky investments.” They also pointed out that cryptocurrencies may not align with the foundation’s commitment to environmental sustainability. 

One of the biggest controversies surrounding cryptocurrencies is that mining, spending and trading them use massive amounts of energy. That’s the reason why Mozilla caught flak after it announced that it would start accepting crypto donations, prompting the organization to put its plans on hold. According to a Bitcoin Energy Consumption Index, those processes use up 204.50 terawatt-hours of electricity per year, which is comparable to what’s consumed by some countries, such as Thailand. Wikimedia accepts Bitcoin, Bitcoin Cash and Ether.

GorillaWarfare’s proposal welcomed comments over three months starting in January. In all, 232 users voted in favor of the proposal, while 94 voted against. Those who argued in favor of cryptocurrency donations explained that they provide safer ways to donate and that fiat currencies have environmental issues of their own. 

Even though the community voted in favor of blocking crypto donations, it’s still just a request that the Wikimedia Foundation may or may not grant. A spokesperson from the foundation told Ars:

“We are aware of the community’s request that the Foundation consider ending our acceptance of donations in cryptocurrency. Our Fundraising team is reviewing the request and related discussions and we will provide additional information once they complete that process.”
