AI Daily Briefing — 2026-05-21

In a Dallas laboratory, baby chicks have been observed attempting to hatch from transparent, 3D-printed plastic cups rather than traditional eggshells. Biotech firm Colossal Biosciences announced this week that it has developed what it calls a 'fully artificial egg' as part of its ambitious project to resurrect extinct bird species such as the dodo and the giant moa. While the company touts this as a major breakthrough, some researchers caution that the achievement may be overstated, though they acknowledge it could pave the way for future artificial womb technology.

Separately, Elon Musk has lost his high-profile lawsuit against OpenAI, which accused cofounders Sam Altman and Greg Brockman of deceiving him about the company's nonprofit mission. In an exclusive roundtable discussion, MIT Technology Review AI reporter and attorney Michelle Kim analyzed the courtroom proceedings and their implications for the broader AI race, noting that the verdict could reshape how AI companies define their charitable and commercial goals.

In other developments, cryobiologist Greg Fahy continues to study the cryopreserved brain of his late friend L. Stephen Coles, stored at minus 146 degrees Celsius in Arizona. Coles hoped for eventual reanimation, a goal Fahy still believes possible. While many experts remain skeptical, Fahy's work is advancing cryopreservation techniques that could improve organ transplantation.

Meanwhile, AI researchers are moving beyond large language models to develop 'world models' that understand physical environments. Companies like Google DeepMind and World Labs are leading this shift, which MIT Technology Review AI explores in an upcoming roundtable discussion on May 21.

Colossal Biosciences has announced a breakthrough in avian reproduction: chicks growing inside transparent, 3D-printed plastic cups rather than natural eggs. The biotech firm, based in Dallas, describes the invention as a “fully artificial egg” designed to support embryonic development outside a biological shell. The device features an oval-shaped printed lattice coated with a silicone membrane that allows oxygen exchange, mimicking a real eggshell’s function. Researchers transferred the contents of recently laid chicken eggs into these artificial shells, where the embryos continued to grow, with a window on top enabling observation.

Company officials say the technology could aid conservation efforts for at-risk bird species and support their broader mission to resurrect extinct birds like the dodo and the giant moa. The moa, a 12-foot-tall flightless bird from New Zealand, laid eggs larger than any living bird’s, and Colossal has already prototyped a massive version of its artificial egg, nicknamed the “salad spinner.” However, recreating the moa remains distant, requiring extensive genetic editing of an existing bird’s genome using DNA from ancient bones.

Critics argue Colossal is overstating its achievement. Japanese researcher Katsuya Obara, who hatched chicks under transparent plastic film in 2024, called the “first-ever shell-less incubation system” claim an overstatement, noting similar work dates back to 1998 with quail. Colossal’s potential advance lies in its specialized membrane, which provides better oxygen access without supplementation. The company has faced skepticism before, including over its widely disputed claim of recreating the extinct dire wolf.

As Google kicks off its annual I/O developer conference in Mountain View, California, the tech giant finds itself trailing behind rivals in the foundation model race. A year ago, Google was riding high on the success of Gemini 2.5 Pro, but now its coding tools lag significantly behind Anthropic's Claude Code and OpenAI's Codex. The gap has become so pronounced that some DeepMind engineers have reportedly been allowed to use Claude for their work to avoid falling further behind. Observers will be watching closely for any major coding releases, possibly an update to the Antigravity platform, though expectations remain tempered given the company's recent struggles.

Beyond coding, Google's strengths in AI for science remain a bright spot. The company is the only frontier AI lab to have earned a Nobel Prize, and it has continued releasing innovative tools like the AI co-scientist and AlphaEvolve. Any new scientific announcements at I/O will be noteworthy. Additionally, Google's moves in health AI will be scrutinized, especially with the public release of its AI-powered Health Coach. While OpenAI has dominated the health AI conversation since ChatGPT Health launched in January, Google's cautious approach may reflect either a strategic gap or prudent restraint in a high-stakes field.

The conference also unfolds against a backdrop of industry drama, with tensions between tech leaders like Elon Musk and Sam Altman simmering just 30 miles north in Oakland. For Google, the challenge is clear: reclaim its position as a frontrunner in AI while leveraging its unique strengths in science and health.

Time is running out for early-stage founders seeking a major platform. Applications for the Startup Battlefield 200 close on May 27, giving startups just one week to secure a spot at TechCrunch Disrupt 2026, scheduled for October 13-15. Selected companies gain access to venture capitalists, global media attention, TechCrunch coverage, and $100,000 in equity-free funding. Founders are urged to submit their applications promptly, as last-minute entries risk being overlooked amid the final surge.

Startup Battlefield 200 has a proven history of launching category-defining companies. Past participants include Dropbox, Cloudflare, and Discord, which began as unpolished pitches before becoming industry giants. The program is not about perfection—pre-revenue and pre-launch startups are welcome. What matters is a transformative idea. Founders or those who know promising startups should nominate them now to allow time for a complete application before the deadline.

Selected startups will showcase live on the Disrupt Stage before over 10,000 attendees, including top investors and media. Benefits include a fully funded exhibition booth, free team passes, pitch training, founder masterclasses with leading VCs, and a featured profile in the event app. Participants also gain press list access and opportunities for TechCrunch editorial coverage, podcasts, and speaking engagements. Every company pitches, either on the main stage or the Pitch Showcase Stage, ensuring direct exposure to key industry players.

The track record speaks for itself: over 1,700 companies have competed in Startup Battlefield 200, collectively raising more than $32 billion and achieving over 250 exits, including acquisitions by major firms. This is a chance to join that legacy. Apply or nominate a startup before May 27 to take the first step toward defining the next wave of innovation.

Gavriel Cohen, the creator of the security-focused AI tool NanoClaw, turned down a $20 million acquisition offer and instead raised a $12 million seed round led by Valley Capital Partners. The round, which was oversubscribed, also saw participation from Docker, Vercel, Monday.com, Slow Ventures, and angel investors including Hugging Face CEO Clem Delangue. The funding comes just weeks after NanoClaw went viral, attracting endorsements from AI researcher Andrej Karpathy and Singapore’s foreign minister.

Cohen, who built NanoClaw alongside his brother Lazer, said the project exploded in popularity after Karpathy praised it on X and the Singaporean minister called it his “second brain” in a viral Facebook post. Within six weeks of writing the first line of code, Cohen received a $20 million buyout offer that included jobs for the brothers. They declined, believing the open-source project could grow exponentially more valuable as its community expanded.

NanoClaw was originally created as a secure alternative to OpenClaw for the Cohens’ previous AI marketing startup. Unlike traditional agents that run directly on a computer, NanoClaw operates in a sandboxed container, a security practice that has since become more common. After shuttering their earlier venture, the brothers focused entirely on NanoClaw, which now has thousands of users and has begun onboarding enterprise customers based on community feedback.

Docker and Vercel have already partnered with NanoCo, and the company is exploring integrations with hardware like Hugging Face’s Reachy Mini robot. Cohen noted that the project’s rapid growth has been fueled by a dedicated open-source community that contributes code and demonstrates new use cases. Despite the early acquisition offers, the brothers remain committed to building NanoClaw independently, with plans to expand its enterprise footprint.
