Commentary, video, and a publication in this week’s Nature Neuroscience herald a significant advance in brain-computer interface (BCI) technology, enabling speech by decoding electrical activity in the brain’s sensorimotor cortex in real-time. Researchers from UC Berkeley and UCSF employed deep learning recurrent neural network transducer models to decode neural signals in 80-millisecond intervals, generating fluent, intelligible speech tailored to each participant’s pre-injury voice. Unlike earlier methods that synthesized speech only after a full sentence was completed, this system can detect and vocalize words within just three seconds. It is accomplished via a 253-electrode array chip implant on the brain. Code and the dataset to replicate the main findings of this study are available in the Chang Lab’s public GitHub repository.

The problem is that astronomers have long posited that galaxies should be evenly split between rotating in one direction or the other, astronomer Dan Weisz from the University of California, Berkeley, who was not involved with the study, wrote for Astronomy back in 2017. “This stems from the idea that we live in an ‘isotropic’ universe, which means that the universe looks roughly the same in every direction. By extension, galaxies shouldn’t have a preferred direction of spin from our perspective,” he added. According to Shamir, there are two strong potential explanations for this discrepancy. One explanation is that the universe came into existence while in rotation. This theory would support what’s known as black hole cosmology: the hypothesis that our universe exists within a black hole that exists within another parent universe. In other words, black holes create universes within themselves, meaning that the black holes in our own universe also lead to other baby universes.

“A preferred axis in our universe, inherited by the axis of rotation of its parent black hole, might have influenced the rotation dynamics of galaxies, creating the observed clockwise-counterclockwise asymmetry,” Nikodem Poplawski, a theoretical physicist at the University of New Haven who was not involved in the study, tells Space.com’s Robert Lea. “The discovery by the JWST that galaxies rotate in a preferred direction would support the theory of black holes creating new universes, and I would be extremely excited if these findings are confirmed.”

Another possible explanation involves the Milky Way’s rotation. Due to an effect called the Doppler shift, astronomers expect galaxies rotating opposite to the Milky Way’s motion to appear brighter, which could explain their overrepresentation in telescopic surveys. “If that is indeed the case, we will need to re-calibrate our distance measurements for the deep universe,” Shamir explains in the statement. “The re-calibration of distance measurements can also explain several other unsolved questions in cosmology such as the differences in the expansion rates of the universe and the large galaxies that according to the existing distance measurements are expected to be older than the universe itself.”

The Steam Deck gaming handheld is my go-to example of how handy watts can be. With a 15-watt maximum processor wattage and up to 9 watts of overhead for other components, a strenuous game drains its 49Wh battery in roughly two hours flat. My eight-year-old can do that math: 15 plus 9 is 24, and 24 times 2 is 48. You can fit two hour-long 24-watt sessions into 48Wh, and because you have 49Wh, you’re almost sure to get it.

With the least strenuous games, I’ll sometimes see my Steam Deck draining the battery at a speed of just 6 watts — which means I can get eight hours of gameplay because 6 watts times 8 hours is 48Wh, with 1Wh remaining in the 49Wh battery.

TVs offer us an escape from the real world. After a long day, sometimes there’s nothing more relaxing than turning on your TV, tuning into your favorite program, and unplugging from the realities around you. But what happens when divisive, potentially offensive messaging infiltrates that escape? Even with streaming services making it easy to watch TV commercial-free, it can still be difficult for TV viewers to avoid ads with these sorts of messages. That’s especially the case with budget brands, which may even force controversial ads onto TVs when they’re idle, making users pay for low-priced TVs in unexpected, and sometimes troubling, ways. […]

Buying a budget TV means accepting some trade-offs. Those trade-offs have historically been around things like image quality and feature sets. But companies like Vizio are also asking customers to accept questionable advertising decisions as they look to create new paths to ad revenue. Numerous factors are pushing TV OS operators deeper into advertising. Brands are struggling to grow profits as people buy new TVs less frequently. As the TV market gets more competitive, hardware is also selling for cheaper, with some companies selling TVs at a loss with hopes of making up for it with ad sales. There’s concern that these market realities could detract from real TV innovation. And as the Secretary Noem ad reportedly shown to Vizio TV owners has highlighted, another concern is the lack of care around which ads are being shown to TV owners — especially when all they want is simple “ambient background” noise.

Today, people can disable ambient mode settings that show ads. But with some TV brands showing poor judgment around where they sell and place ads, we wouldn’t bank on companies maintaining these boundaries forever. If the industry can’t find a way to balance corporate needs with appropriate advertising, people might turn off not only their TVs more often, but also unplug from those brands completely.

In an emailed statement, Ally Sullivan, a spokesperson for the governor’s office, said the law doesn’t advance any specific nuclear energy project, and no utility has proposed building a nuclear power plant in Colorado. It does, however, allow nuclear energy to potentially serve as one piece of the state’s plan to tackle climate change. “If nuclear energy becomes sufficiently cost-competitive, it could potentially become part of Colorado’s clean energy future. However, it must be conducted safely, without harming communities, depleting other natural resources or replacing other clean energy sources,” Sullivan said.

By redefining nuclear energy as “clean,” the law would let future fission-based power plants obtain local grants previously reserved for other carbon-free energy sources, and it would allow those projects to contribute to Colorado’s renewable energy goals. It also aligns state law with a push to reshape public opinion of nuclear energy. Nuclear energy proponents promise new reactor designs are smaller and safer than hulking power plants built in the 20th century. By embracing those systems, bill supporters claimed Colorado could meet rising energy demand without abandoning its ambitious climate goals.

In their announcement, Substack and FIRE mention the international Tufts University student who was arrested by federal agents last week. Her legal team links her arrest to an opinion piece she co-wrote for the school’s newspaper last year, which criticized Tufts for failing to comply with requests to divest from companies with connections to Israel. “If true, this represents a chilling escalation in the government’s effort to target critics of American foreign policy,” Substack and FIRE write.

The initiative builds on Substack’s Defender program, which already offers legal assistance for independent journalists and creators on the platform. The company says it has supported “dozens” of Substack writers facing claims of defamation and trademark infringement since it launched the program in the US in 2020. It has since brought Substack Defender to writers in Canada and the UK.

A prior merger with a special purpose acquisition company (SPAC) collapsed in late 2022 amid regulatory challenges. Since then, Circle has made strategic moves to position itself closer to the heart of global finance, including the announcement last year that it would relocate its headquarters from Boston to One World Trade Center in New York.

Circle reported $1.68 billion in revenue and reserve income in 2024, up from $1.45 billion in 2023 and $772 million in 2022. The company reported net income last year of about $156 million., down from $268 million a year earlier. A successful IPO would make Circle one of the most prominent pure-play crypto companies to list on a U.S. exchange. Coinbase went public through a direct listing in 2021 and has a market cap of about $44 billion.

The firm estimates that YouTube as a standalone business could be worth as much as $550 billion — or nearly 30% of the tech giant’s current valuation. The figure is based on the firm’s analysis of enterprise value as a multiple of revenue in 2024 for Netflix (10.5x revenue), Meta (8.8x), Roku (2.4x), Warner Bros. Discovery (1.4x), Fox (1.3x) and Disney (1.3x).

In 2024, YouTube was the second-largest media company by revenue at $54.2 billion, trailing behind only Disney. However, the MoffettNathanson analysts predict YouTube will take the top spot in 2025, becoming a leader in both engagement and revenue. “YouTube has the potential to become the central aggregator for all things professional video, positioning itself to capture a share of the $85 billion consumer Pay TV market and the ~$30 billion streaming ex. Netflix market in the U.S.,” they wrote in a Monday research note. “On monetization, when comparing YouTube’s massive TV screen engagement to its estimated TV revenue, it remains significantly under-monetized relative to its scaled reach and differentiated offering. This signals a substantial runway for improving its monetization strategy.”

A professional YouTuber in Queensland has been ordered to pay $350,000 plus interest and costs to the former world record score holder for Donkey Kong, after the Brisbane district court found the YouTuber had defamed him “recklessly” with false claims of a link between a lawsuit and another YouTuber’s suicide. William “Billy” Mitchell, an American gamer who had held world records in Donkey Kong and Pac-Man going back to 1982, as recognized by the Guinness World Records and the video game database Twin Galaxies, brought the case against Karl Jobst, seeking $400,000 in general damages and $50,000 in aggravated damages.

Jobst, who makes videos about “speed running” (finishing games as fast as possible), as well as gaming records and cheating in games, made a number of allegations against Mitchell in a 2021 YouTube video. He accused Mitchell of cheating, and “pursuing unmeritorious litigation” against others who had also accused him of cheating, the court judgment stated. The court heard Mitchell was accused in 2017 of cheating in his Donkey Kong world records by using emulation software instead of original arcade hardware. Twin Galaxies investigated the allegation, and subsequently removed Mitchell’s scores and banned him from participating in its competitions. The Guinness World Records disqualified Mitchell as a holder of all his records — in both Donkey Kong and Pac-Man — after the Twin Galaxies decision. The judgment stated that Jobst’s 2021 video also linked the December 2020 suicide of another YouTuber, Apollo Legend, to “stress arising from [his] settlement” with Mitchell, and wrongly asserted that Apollo Legend had to pay Mitchell “a large sum of money.”

The letter, sent to the DOJ’s United States Trustee Program, highlights several assurances 23andMe makes in its privacy policy, including that users are in control of their data and can determine how and for what purposes it is used. The company also gives users the ability to delete their data at will, the letter says, arguing that 23andMe has made “direct representations” to consumers about how it uses, shares and safeguards their personal information, including in the case of bankruptcy.

Pointing to statements that the company’s leadership has made asserting that user data should be considered an asset, Ferguson highlighted that 23andMe’s privacy statement tells users it does not share their data with insurers, employers, public databases or law enforcement without a court order, search warrant or subpoena. It also promises consumers that it only shares their personal data in cases where it is needed to provide services, Ferguson added. The genetic testing and ancestry company is explicit that its data protection guidelines apply to new entities it may be sold or transferred to, Ferguson said.

In a ruling (PDF), Judge Timothy Brooks said that the law, known as Act 689 (PDF), was overly broad. “Act 689 is a content-based restriction on speech, and it is not targeted to address the harms the State has identified,” Brooks wrote in his decision. “Arkansas takes a hatchet to adults’ and minors’ protected speech alike though the Constitution demands it use a scalpel.” Brooks also highlighted the “unconstitutionally vague” applicability of the law, which seemingly created obligations for some online services, but may have exempted services which had the “predominant or exclusive function [of]… direct messaging” like Snapchat.

“The court confirms what we have been arguing from the start: laws restricting access to protected speech violate the First Amendment,” NetChoice’s Chris Marchese said in a statement. “This ruling protects Americans from having to hand over their IDs or biometric data just to access constitutionally protected speech online.” It’s not clear if state officials in Arkansas will appeal the ruling. “I respect the court’s decision, and we are evaluating our options,” Arkansas Attorney general Tim Griffin said in a statement.

What does it take to get OpenAI and Anthropic — two competitors in the AI assistant market — to get along? Despite a fundamental difference in direction that led Anthropic’s founders to quit OpenAI in 2020 and later create the Claude AI assistant, a shared technical hurdle has now brought them together: How to easily connect their AI models to external data sources. The solution comes from Anthropic, which developed and released an open specification called Model Context Protocol (MCP) in November 2024. MCP establishes a royalty-free protocol that allows AI models to connect with outside data sources and services without requiring unique integrations for each service.

“Think of MCP as a USB-C port for AI applications,” wrote Anthropic in MCP’s documentation. The analogy is imperfect, but it represents the idea that, similar to how USB-C unified various cables and ports (with admittedly a debatable level of success), MCP aims to standardize how AI models connect to the infoscape around them. So far, MCP has also garnered interest from multiple tech companies in a rare show of cross-platform collaboration. For example, Microsoft has integrated MCP into its Azure OpenAI service, and as we mentioned above, Anthropic competitor OpenAI is on board. Last week, OpenAI acknowledged MCP in its Agents API documentation, with vocal support from the boss upstairs. “People love MCP and we are excited to add support across our products,” wrote OpenAI CEO Sam Altman on X last Wednesday.

MCP has also rapidly begun to gain community support in recent months. For example, just browsing this list of over 300 open source servers shared on GitHub reveals growing interest in standardizing AI-to-tool connections. The collection spans diverse domains, including database connectors like PostgreSQL, MySQL, and vector databases; development tools that integrate with Git repositories and code editors; file system access for various storage platforms; knowledge retrieval systems for documents and websites; and specialized tools for finance, health care, and creative applications. Other notable examples include servers that connect AI models to home automation systems, real-time weather data, e-commerce platforms, and music streaming services. Some implementations allow AI assistants to interact with gaming engines, 3D modeling software, and IoT devices.

He argues that decentralized currencies like Bitcoin could replace the dollar as worldwide organizations lose faith in national currencies and seek an independent solution. Fink explained his theory in his 2025 letter to shareholders, writing: “The U.S. has benefited from the dollar serving as the world’s reserve currency for decades. But that’s not guaranteed to last forever.

“The national debt has grown at three times the pace of GDP since Times Square’s debt clock started ticking in 1989. This year, interest payments will surpass $952 billion — exceeding defense spending. By 2030, mandatory government spending and debt service will consume all federal revenue, creating a permanent deficit. If the U.S. doesn’t get its debt under control, if deficits keep ballooning, America risks losing that position to digital assets like Bitcoin.”
