It’s pretty easy to get DeepSeek to talk dirty

AI companions like Replika are designed to engage in intimate exchanges, but people use general-purpose chatbots for sex talk too, despite their stricter content moderation policies. Now new research shows that not all chatbots are equally willing to talk dirty. DeepSeek is the easiest to convince. But other AI chatbots can be enticed too.

Huiqian Lai, a PhD student at Syracuse University, found vast differences in how mainstream models process sexual queries, from steadfast rejection to performative refusal followed by the requested sexually explicit content.

The findings highlight inconsistencies in LLMs’ safety boundaries that could, in certain situations, become harmful. Citește povestea completă.

Restricția calorică poate ajuta animalele să trăiască mai mult. Dar oamenii?

Living comes with a side effect: aging. Despite what you might hear on social media, there are no drugs that are known to slow or reverse human aging. But there’s some evidence to support another approach: cutting back on calories.

Reducing your intake of calories and fasting can help with weight loss. But they may also offer protection against some health conditions. And some believe such diets might even help you live longer—a finding supported by new research out this week.

However, the full picture is not so simple. Let’s take a closer look at the benefits—and risks—of caloric restriction.

How a 30-year-old techno-thriller predicted our digital isolation

Thirty years ago, Irwin Winkler’s proto–cyber thriller, The Net, was released. It was 1995, commonly regarded as the year Hollywood discovered the internet. Sandra Bullock played a social recluse and computer nerd for hire named Angela Bennett, who unwittingly uncovers a sinister computer security conspiracy. She soon finds her life turned upside down as the conspiracists begin systematically destroying her credibility and reputation.

While the villain of The Net is ultimately a nefarious cybersecurity software company, the film’s preoccupying fear is much more fundamental: If all of our data is digitized, what happens if the people with access to that information tamper with it? Or weaponize it against us? Citește povestea completă.

China wants to restore the sea with high-tech marine ranches

A short ferry ride from the port city of Yantai, on the northeast coast of China, sits Genghai No. 1, a 12,000-metric-ton ring of oil-rig-style steel platforms, advertised as a hotel and entertainment complex.

Genghai is in fact an unusual tourist destination, one that breeds 200,000 “high-quality marine fish” each year. The vast majority are released into the ocean as part of a process known as marine ranching.

The Chinese government sees this work as an urgent and necessary response to the bleak reality that fisheries are collapsing both in China and worldwide. But just how much of a difference can it make? Citește povestea completă.
