OpenClaw security fears lead Meta, other AI firms to restrict its use

OpenClaw security fears lead Meta, other AI firms to restrict its use

Last month, Jason Grad issued a late-night warning to the 20 employees at his tech startup. “You've likely seen Clawdbot trending on X/LinkedIn. While cool, it is currently unvetted and high-risk for our environment," he wrote in a Slack message with a red siren emoji. “Please keep Clawdbot off all company hardware and away from work-linked accounts.”

Grad isn’t the only tech executive who has raised concerns to staff about the experimental agentic AI tool, which was briefly known as MoltBot and is now named OpenClaw. A Meta executive says he recently told his team to keep OpenClaw off their regular work laptops or risk losing their jobs. The executive told reporters he believes the software is unpredictable and could lead to a privacy breach if used in otherwise secure environments. He spoke on the condition of anonymity to speak frankly.

Peter Steinberger, OpenClaw’s solo founder, launched it as a free, open source tool last November. But its popularity surged last month as other coders contributed features and began sharing their experiences using it on social media. Last week, Steinberger joined ChatGPT developer OpenAI, which says it will keep OpenClaw open source and support it through a foundation.

Lawsuit: EPA revoking greenhouse gas finding risks “thousands of avoidable deaths”

Lawsuit: EPA revoking greenhouse gas finding risks “thousands of avoidable deaths”

In a lawsuit filed Wednesday, the Environmental Protection Agency was accused of abandoning its mission to protect public health after repealing an "endangerment finding" that has served as the basis for federal climate change regulations for 17 years.

The lawsuit came from more than a dozen environmental and health groups, including the American Public Health Association, the American Lung Association, the Center for Biological Diversity (CBD), the Clean Air Council, the Environmental Defense Fund (EDF), the Natural Resources Defense Council (NRDC), the Sierra Club, and the Union of Concerned Scientists.

The groups have asked the US Court of Appeals for the District of Columbia Circuit to review the EPA decision, which also eliminated requirements controlling greenhouse gas emissions in new cars and trucks. Urging a return to the status quo, the groups argued that the Trump administration is anti-science and illegally moving to benefit the fossil fuel industry, despite a mountain of evidence demonstrating the deadly consequences of unchecked pollution and climate change-induced floods, droughts, wildfires, and hurricanes.

Record scratch—Google's Lyria 3 AI music model is coming to Gemini today

Record scratch—Google's Lyria 3 AI music model is coming to Gemini today

The American poet Henry Wadsworth Longfellow called music "the universal language of mankind." Is that still true when the so-called music is being generated by a probabilistic robot instead of a human? We're about to find out. Google has announced its latest Lyria 3 AI model is being deployed in the Gemini app, vastly expanding access to AI music generation.

Google DeepMind has been tinkering with Lyria for a while now, offering limited access in developer-oriented products like Vertex AI. Lyria 3 is more capable than previous versions, and it's also quicker to use. Just select the new "Create music" option in the Gemini app or web UI to get started. You can describe what you want and even upload an image to help the robot get the right vibe. And in a few seconds, you get music (or something like it).

In case there was any uncertainty about whether Lyria tracks still counted as a human artistic endeavor, worry not! Unlike past versions of the model, you don't even have to provide lyrics in your prompt. You can be vague with your request, and the model will create suitable lyrics for the 30-second song. Although with that limit, "jingle" might be more accurate.

Google's Pixel 10a arrives on March 5 for $499 with specs and design of yesteryear

Google's Pixel 10a arrives on March 5 for $499 with specs and design of yesteryear

It's that time of year—a new budget Pixel phone is about to hit virtual shelves. The Pixel 10a will be available on March 5, and pre-orders go live today. The 9a will still be on sale for a while, but the 10a will be headlining Google's store. However, you might not notice unless you keep up with the Pixel numbering scheme. This year's A-series Pixel is virtually identical to last year's, both inside and out.

Last year's Pixel 9a was a notable departure from the older design language, but Google made few changes for 2026. We liked that the Pixel 9a emphasized battery capacity and moved to a flat camera bump, and this time, it's really flat. Google says the camera now sits totally flush with the back panel. This is probably the only change you'll be able to identify visually.

Specs at a glance: Google Pixel 9a vs. Pixel 10a
Phone Pixel 9a Pixel 10a
SoC Google Tensor G4 Google Tensor G4
Memory 8GB 8GB
Storage 128GB, 256GB 128GB, 256GB

Measurements 154.7×73.3×8.9 mm; 185 g 153.9×73×9 mm; 183 g

Google also says the new Pixel will have a slightly upgraded screen. The resolution, size, and refresh rate are unchanged, but peak brightness has been bumped from 2,700 nits to 3,000 nits (the same as the base model Pixel 10). Plus, the cover glass has finally moved beyond Gorilla Glass 3 to Gorilla Glass 7i, which supposedly has improved scratch and drop protection.

X-rays reveal kingfisher feather structure in unprecedented detail

X-rays reveal kingfisher feather structure in unprecedented detail

In Qing dynasty China, artisans augmented decorative pieces by incorporating iridescent kingfisher feathers—a technique known as tian-tsui. Scientists at Northwestern University's Center for Scientific Studies in the Arts have used high-energy X-ray imaging to achieve unprecedented nanoscale resolution of the unique structure of those feathers, presenting their findings at the annual meeting of the American Association for the Advancement of Science.

As previously reported, nature is the ultimate nanofabricator. The bright iridescent colors in butterfly wings, soap bubbles, opals, or beetle shells don’t come from any pigment molecules but from how they are structured—naturally occurring photonic crystals. In nature, scales of chitin (a polysaccharide common to insects), for example, are arranged like roof tiles. Essentially, they form a diffraction grating, except photonic crystals only produce specific colors, or wavelengths, of light, while a diffraction grating will produce the entire spectrum, much like a prism. In the case of kingfisher feathers, the color is due to the microscopic ridges that cover the parallel rows of keratin strands that grow along the central shaft.

Also known as photonic band-gap materials, photonic crystals are “tunable,” which means they are precisely ordered to block certain wavelengths of light while letting others through. Alter the structure by changing the size of the tiles, and the crystals become sensitive to a different wavelength. They are used in optical communications as waveguides and switches, as well as in filters, lasers, mirrors, and various anti-reflection stealth devices.

Inside the DHS forum where ICE agents trash talk one another

Inside the DHS forum where ICE agents trash talk one another

Every day, people log into an online forum for current and former Homeland Security Investigations (HSI) officers to share their thoughts on the news of the day and complain about their colleagues in Immigration and Customs Enforcement (ICE).

“ERO is too busy dressing up as Black Ops Commandos with Tactical body armor, drop down thigh rigs, balaclavas, multiple M4 magazines, and Punisher patches, to do an Admin arrest of a non criminal, non-violent EWI that weighs 90 pounds and is 5 foot 2, inside a secure Federal building where everyone has been screened for weapons,” wrote one user in July 2025. (ERO stands for Enforcement and Removal Operations; along with HSI, it’s one of the two major divisions of ICE, and is responsible for detaining and deporting immigrants.)

The forum describes itself as a space for current and prospective HSI agents, “designed for the seasoned HSI Special Agent as well as applicants for entry level Special Agent positions.” HSI is the division within ICE whose agents are normally responsible for investigating crimes like drug smuggling, terrorism, and human trafficking.

Password managers' promise that they can't see your vaults isn't always true

Password managers' promise that they can't see your vaults isn't always true

Over the past 15 years, password managers have grown from a niche security tool used by the technology savvy into an indispensable security tool for the masses, with an estimated 94 million US adults—or roughly 36 percent of them—having adopted them. They store not only passwords for pension, financial, and email accounts, but also cryptocurrency credentials, payment card numbers, and other sensitive data.

All eight of the top password managers have adopted the term “zero knowledge” to describe the complex encryption system they use to protect the data vaults that users store on their servers. The definitions vary slightly from vendor to vendor, but they generally boil down to one bold assurance: that there is no way for malicious insiders or hackers who manage to compromise the cloud infrastructure to steal vaults or data stored in them. These promises make sense, given previous breaches of LastPass and the reasonable expectation that state-level hackers have both the motive and capability to obtain password vaults belonging to high-value targets.

A bold assurance debunked

Typical of these claims are those made by Bitwarden, Dashlane, and LastPass, which together are used by roughly 60 million people. Bitwarden, for example, says that “not even the team at Bitwarden can read your data (even if we wanted to).” Dashlane, meanwhile, says that without a user’s master password, “malicious actors can’t steal the information, even if Dashlane’s servers are compromised.” LastPass says that no one can access the “data stored in your LastPass vault, except you (not even LastPass).”
