AI on the couch: Anthropic gives Claude 20 hours of psychiatry

AI on the couch: Anthropic gives Claude 20 hours of psychiatry

The AI company Anthropic released a 244-page "system card" (PDF) this week describing its newest model, Claude Mythos. The model is "our most capable frontier model to date," the company says, and supposedly is so good that Anthropic has decided "not to make it generally available." (The company claims that Mythos is too good at finding unknown cybersecurity bugs, and so the model is only being released to select companies like Microsoft and Apple for now.)

Whatever the truth of this claim, the system card is a fascinating document. Anthropic is well-known as one of the more "AI might be conscious!" companies in the industry, and its new system card claims that as models become more powerful, "It becomes increasingly likely that they have some form of experience, interests, or welfare that matters intrinsically in the way that human experience and interests do."

The company isn't sure about this, it makes clear, but it says that "our concern is growing over time."

Clinical trial shows gene editing works for β-Thalassaemia, too

Clinical trial shows gene editing works for β-Thalassaemia, too

Almost as soon as researchers started exploring the capabilities of the CRISPR/Cas9 system, they recognized its potential use in targeted gene editing. But the intervening decades have seen slow progress as people worked to determine how to do so in a way that would be safe for use in humans. It was only a little over two years ago, decades after CRISPR's discovery, that the FDA approved the first CRISPR-based therapy, for sickle-cell anemia.

Now, following up on that success, a large Chinese collaboration has followed up with a description of an improved gene editing system that produces more focused changes and fewer mistakes. And they've used it to produce a therapy that addresses a disease that's closely related to sickle-cell anemia: β-Thalassaemia.

Gene editing and its limits

The CRISPR/Cas-9 system provides bacteria with a form of immunity. It uses specially structured RNAs (called guide RNAs) that can base-pair with a targeted sequence. The Cas-9 protein then recognizes this structure and cuts the DNA nearby. This is quite effective when the guide RNA can base-pair with a DNA virus, as the resulting cut will inactivate the virus.

“Negative” views of Broadcom driving thousands of VMware migrations, rival says

“Negative” views of Broadcom driving thousands of VMware migrations, rival says

Amid customer dissatisfaction around Broadcom's VMware takeover, rivals have been trying to lure customers from the leading virtualization firm. One of VMware's biggest competitors, Nutanix, claims to have swiped tens of thousands of VMware customers.

Speaking at a press briefing at Nutanix’s .NEXT conference in Chicago this week, Nutanix CEO Rajiv Ramaswami said that “about 30,000 customers” have migrated from VMware to the rival platform, pointing to customer disapproval over Broadcom’s VMware strategy, SDxCentral, a London-based IT publication, reported today.

“I think there's no doubt that the customer sentiment continues to be negative about Broadcom,” Ramaswami said, per SDxCentral.

Ugandan chimps split into two factions, then killed rivals

Ugandan chimps split into two factions, then killed rivals

In the 1970s, the late Jane Goodall observed a community of chimpanzees in Gombe, Tanzania, breaking into two factions; the males in one group ended up killing all the males in the rival group over the next four years, along with one female chimp. But the case was considered an anomaly, although there is genetic evidence suggesting this kind of split is a rare event occurring every 500 years or so. Now researchers have observed the largest known community of Ngogo chimpanzees in Uganda also permanently splitting into two rival groups with a similar outbreak of violence, according to a new paper published in the journal Science.

"What's especially striking is that the chimpanzees are killing former group members," said co-author Aaron Sandel, an anthropologist at the University of Texas, Austin. "The new group identities are overriding cooperative relationships that had existed for years. I would caution against anyone calling this a civil war. But the polarization and collective violence that we have observed with these chimpanzees may give us insight into our own species."

The authors analyzed 24 years' worth of data from social networks, 10 years of GPS tracking, and 30 years of demographic data on the Ngogo chimps in Uganda's Kibale National Park. They identified three distinct phases to the split. First there was an abrupt shift as chimp relationships became polarized into two distinct clusters: Western and Central. The chimps then spent the next two years increasingly avoiding those in their rival cluster; there were very few interactions across clusters, and Western male chimps started patrolling their territory, showing increased aggression toward Central males. By 2018, the fissure had become permanent.

The gravity of their experience hasn't quite set in for the Artemis II astronauts

The gravity of their experience hasn't quite set in for the Artemis II astronauts

On the home stretch of their nine-day mission, the four astronauts flying aboard NASA's Orion spacecraft are just beginning to reflect on their experience of flying beyond the Moon.

Their memories of Monday's encounter with the Moon are still fresh as they return to Earth, heading for reentry and splashdown in the Pacific Ocean on Friday evening.

"I'm actually getting chills right now just thinking about it. My palms are sweating," said Reid Wiseman, commander of the Artemis II mission. "But it is amazing to watch your home planet disappear behind the Moon. You can see the atmosphere. You could actually see the terrain on the Moon projected across the Earth as the Earth was eclipsing behind the Moon. It was just an unbelievable sight, and then it was gone. It was out of sight."

Police corporal created AI porn from driver's license pics

Police corporal created AI porn from driver's license pics

A corporal in the Pennsylvania state police yesterday pleaded guilty to a mind-boggling set of crimes that include going through his co-workers' underwear, possessing a stolen gun, having child sexual abuse material on his hard drives, and using AI tools to create over 3,000 pornographic "deepfakes."

One of the deepfakes involved a district court judge, while many of the others were created based on photos downloaded illicitly from state databases, including driver's license photos.

Some of the imagery was even created at police barracks, using state-owned devices.

LinkedIn scanning users' browser extensions sparks controversy and two lawsuits

LinkedIn scanning users' browser extensions sparks controversy and two lawsuits

LinkedIn is facing two lawsuits over its practice of scanning users' browsers to determine which extensions they're running. Two class action complaints were filed by different law firms on behalf of different plaintiffs Monday in US District Court for the Northern District of California.

Each complaint has one named plaintiff and seeks to represent a proposed class including all LinkedIn users in the US. The complaints seem to rely heavily on the recent "BrowserGate" report by a German entity called Fairlinked, which describes itself as a trade association and advocacy group for commercial LinkedIn users.

Fairlinked appears to be run by the same people behind Teamfluence, an Estonian software company that sued LinkedIn in Munich in January. LinkedIn says Teamfluence distributed a browser extension that scraped LinkedIn user data in violation of the user agreement and that its LinkedIn accounts were suspended.
