Taking a closer look at immune ‘memory’ could spur progress in the fight against lethal illnesses

The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other threats. Vaccines enhance this security system by teaching our immune cells to target specific pathogens. According to the World Health Organization, vaccine-induced immunity saves about six lives every minute. But how long does this protective immune “memory” last?

According to Shane Crotty, Ph.D., Professor and Chief Scientific Officer at La Jolla Institute for Immunology (LJI), we still have much to learn about immune memory.

“There are actually not many studies of human immune memory due to vaccines,” says Crotty. “Scientists traditionally don’t track immune memory past one year after vaccination—or even six months after vaccination—and that’s a bit of a problem.”

Over 100 Chrome Web Store extensions steal user accounts, data

More than 100 malicious extensions in the official Chrome Web Store are attempting to steal Google OAuth2 Bearer tokens, deploy backdoors, and carry out ad fraud.

Researchers at application security company Socket discovered that the malicious extensions are part of a coordinated campaign that uses the same command-and-control (C2) infrastructure.

The threat actor published the extensions under five distinct publisher identities in multiple categories: Telegram sidebar clients, slot machine and Keno games, YouTube and TikTok enhancers, a text translation tool, and utilities.

Elon Musk’s xAI sues over Colorado’s AI antidiscrimination law, claiming it’s a threat to Grok’s free speech

Senate Bill 205, passed in 2024, is one of the nation’s first attempts to regulate ‘high-risk’ AI systems and protect consumers from ‘algorithmic discrimination’ — or disparate treatment or impacts on protected classes under Colorado law.

In the complaint, which was filed in federal court in Denver, Musk’s lawyers contend that the law is ‘unconstitutionally vague’ and ‘invites arbitrary enforcement’ because it fails to define some key terms. They also contend that Colorado’s law would cause Musk’s AI chatbot, Grok, to ‘abandon its disinterested pursuit of truth and instead promote the State’s ideological views on various matters, racial justice in particular,’ which they say violates the First Amendment.

‘Unless the implementation and enforcement of SB24-205 is enjoined, it will violate xAI’s constitutional rights and cause irreparable constitutional harm, impose enormous burdens on xAI and the AI industry, and substitute Colorado’s political preferences for the national economic and security imperative of American AI dominance,’ the complaint reads in part…

…State Rep. Briana Titone, D-Arvada, one of Senate Bill 205’s lead sponsors, told The Sun that Musk’s lawsuit seems like a ‘fishing expedition’ that misinterprets the core of the law.

‘This is where the disconnect is. SB 205 is about consequential decisions, not about freedom of speech,’ Titone said. ‘It’s completely detached from it. And they’re trying to use this argument for a law that has nothing to do with what he’s saying. We’re not restricting speech. Our bill does not say that Grok still can’t be a dick.’


The lawsuit was filed at a time when the Trump administration looks to preempt state regulation of AI models through executive fiat.

Move Reveals Its New Markerless Motion Capture System Genesis

Move, a company focused on motion capture and 3D animation, unveiled Genesis, its new high-quality markerless motion capture system, delivering data quality “comparable to optical systems alongside the reliability, security, and integration required by professional VFX, AAA gaming, and creative studios.”

This is a “foundational strategic shift” from the consumer-focused Move Pro to a dedicated enterprise ecosystem. Genesis has already replaced Move Pro on the company’s site, replacing action cameras with Z-Cam integration.

After Anthropic’s Mythos AI uncovers thousands of zero-day bugs, top US officials huddle with bank CEOs

The heads of America’s biggest banks met this week with Federal Reserve Chairman Jerome Powell and Treasury Secretary Scott Bessent to weigh the security implications of a new artificial intelligence system developed by Anthropic, according to reports Friday.

The gathering was convened on the sidelines of an event in Washington, with officials calling the extra session to address Anthropic’s newly unveiled Claude Mythos model, Bloomberg and the Financial Times reported.

The US Treasury Department did not immediately respond to a request for comment. The Federal Reserve had no comment.

Microsoft: Canadian employees targeted in payroll pirate attacks

A financially motivated threat actor tracked as Storm-2755 is stealing Canadian employees’ salary payments after hijacking their accounts in payroll pirate attacks.

The attackers used malicious Microsoft 365 sign-in pages to steal victims’ authentication tokens and session cookies by redirecting them to domains (e.g., bluegraintours[.]com) hosting malicious web pages (pushed to the top of search engine results through malvertising or SEO poisoning) that masqueraded as Microsoft 365 sign-in forms.

This allowed Storm-2755 to bypass multifactor authentication (MFA) in adversary‑in‑the‑middle (AiTM) attacks by replaying stolen session tokens rather than re-authenticating.
