Colossal Biosciences says it has grown chickens inside 3D-printed artificial eggshells. "The company says the egg technology could help conserve at-risk bird species," reports MIT Technology. "It could also play a role in a project to re-create the extinct giant moa, a flightless 12-foot-tall bird that once lived in New Zealand and laid four-liter eggs, larger than those of any living bird." From the report: The biotech company today claimed it has developed a "fully artificial egg" as part of its effort to resurrect extinct avian species, including birds like the dodo and the giant moa. But "artificial eggshell" would probably be a better description for the invention. It's an oval-shaped printed lattice, coated inside with a special silicone-based membrane that lets in oxygen, just as a real eggshell does. To generate birds, Colossal took recently laid chicken eggs and carefully poured their contents into the artificial shells, where they continued growing. A window on top lets researchers peek inside. "To see them all moving around in their artificial eggs was absolutely mind blowing," says Andrew Pask, the company's chief biology officer. "You really feel you can grow life outside of the womb." [...] The work on the artificial eggshell was carried out in Dallas by Colossal's exogenous development team, or Exo Dev. That group is also trying to develop artificial wombs for mammals, starting with marsupials. "We're looking at every single facet of what's happening during a mammalian pregnancy to unpack exactly how we then go about recapitulating that," says Pask. For that team, an artificial eggshell is a relatively quick and easy technical win. That's because chickens are already an example of ex utero development. After an egg is laid, a small embryo sitting on top of the yolk starts growing, drawing nutrients from the yolk, the white, and even the shell, which provides calcium. (Colossal says it has to add ground-up calcium to the artificial eggs.) In order to create a moa, Colossal will have to genetically alter another type of bird, changing potentially thousands of DNA letters. But so far, chickens are the only bird species that can be genetically engineered. And that's via a tricky process of editing stem cells that produce egg and sperm. Scientists have to add or delete DNA letters from these cells and then inject them back into an egg. The resulting bird will carry the genetic changes in its gonads -- and then be able to pass them on. Pask says Colossal's idea is that it could modify avian stem cells enough to produce moa-like sperm or eggs. But then you might have the odd situation of a chicken laying an egg with a moa embryo inside it. "You would have chickens making moa egg and moa sperm. But it's still a chicken egg," he says.

Intuit is reportedly cutting about 3,000 jobs, or 17% of its workforce, as it restructures around AI and simplifies its corporate organization. TechCrunch reports: The layoffs come during a bad year for the tech workforce. The tech industry has already cut more than 100,000 jobs this year, per Statista, and is on track to outpace both 2024 and 2025 if the layoff trend continues. Companies such as Amazon, Block, Cisco, Cloudflare, Meta, Microsoft, and Oracle have let go of thousands of employees each, all of them citing a need to refocus expenditures around AI projects as a reason to cut jobs and restructure their organizations. [...] Intuit, however, hasn't been perceived as a beneficiary of the AI boom, with its shares consistently underperforming in the broader S&P 500 over the past 12 months. The company has been caught up in the broader current of worries that traditional software-as-a-service firms will not be able to keep up or compete, as new and upcoming AI products and services threaten to change how software is developed and how it is used. In its fiscal second quarter ended January, Intuit reported revenue of $4.65 billion, a 17% increase, and net profit of $693 million, a 48% improvement compared to a year earlier. The company expects revenue to increase by about 10% in the third quarter, for which it will report results later today.

An anonymous reader quotes a report from Ars Technica: Google on Wednesday published exploit code for an unfixed vulnerability in its Chromium browser codebase that threatens millions of people using Chrome, Microsoft Edge, and virtually all other Chromium-based browsers. The proof-of-concept code exploits the Browser Fetch programming interface, a standard that allows long videos and other large files to be downloaded in the background. An attacker can use the exploit to create a connection for monitoring some aspects of a user's browser usage and as a proxy for viewing sites and launching denial-of-service attacks. Depending on the browser, the connections either reopen or remain open even after it or the device running it has rebooted. The unfixed vulnerability can be exploited by any website a user visits. In effect, a compromise amounts to a limited backdoor that makes a device part of a limited botnet. The capabilities are limited to the same things a browser can do, such as visit malicious sites, provide anonymous proxy browsing by others, enable proxied DDoS attacks, and monitor user activity. Nonetheless, the exploit could allow an attacker to wrangle thousands, possibly millions, of devices into a network. Once a separate vulnerability becomes available, the attacker could use it to then compromise all those devices. "The dangerous part here is that you can just have a lot of different browsers together that you can in the future run something on that you figure out," said Lyra Rebane, the independent researcher who discovered the vulnerability and privately reported it to Google in late 2022 in an interview. He said using the exploit code Google prematurely published would be "pretty easy," although scaling it to wrangle large numbers of devices into a single network would require more work. In the thread of Rebane's disclosure to Google, two developers said in separate responses that it was a "serious vulnerability." Its severity was rated S1, the second-highest classification. Since its reporting 29 months ago, the vulnerability remained unknown except to Chromium developers. Then on Wednesday morning, it was published to the Chromium bug tracker. Rebane initially assumed the vulnerability was finally fixed. Shortly thereafter, he learned that, in fact, it remained unpatched. While Google removed the post, it remains available on archival sites, along with the exploit code. Google representatives didn't immediately respond to an email asking how and why it published the vulnerability and if or when a fix would become available. The exploit works by abusing Chromium's Browser Fetch API to open a service worker that remains persistently active. A malicious website can trigger it through JavaScript, creating a connection that can be used "for monitoring some aspects of a user's browser usage and as a proxy for viewing sites and launching denial-of-service attacks," reports Ars. Depending on the browser, those connections "either reopen or remain open even after it or the device running it has rebooted," effectively turning the device into part of a "limited botnet."
