schwit1 shares a report from the New York Times: Pete Kayll, a musclebound veteran of Britain’s Royal Marines, had an unusual instruction for the Bitcoin investors gathered in Switzerland in late October. “Just bite your way out,” he told them. It was the final day of a weekend-long cryptocurrency convention on the shore of Lake Lugano, near the Italian border. A small group of investors had lined up in a conference room to have their hands bound with plastic zipties. Now they were learning how to get them off. “Your teeth will get through anything,” Mr. Kayll advised. “But it will bloody well hurt.”

Most people don’t go to an international crypto conference expecting to learn how to gnaw through plastic. But after hours of panels devoted to topics like Bitcoin-collateralized loans, these investors were looking for something more practical. They wanted to know what to do if they were grabbed on the street and thrown into the back of a van. Already paranoid about scams, hacks and market turmoil, wealthy crypto investors have lately become terrified about a much graver threat: torture and kidnapping. These threats are known as “wrench attacks,” which is a reference to a popular XKCD cartoon where a thief skips the hacking and just uses a wrench to force out the password.

According to the NYT, the best way to stay protected is staying low-profile, minimizing visible signs of wealth, using basic physical security tools, and preparing for self-defense. The report specifically recommends avoiding flashy displays of wealth like luxury watches and cars, watching for honey-traps, using hotel door stoppers, practicing escape techniques such as breaking zip-ties, hiring discreet bodyguards, and relying on panic-button apps like Glok to summon help quickly.

UC Berkeley researchers working with Project CETI discovered that sperm whales produce vowel-like sounds embedded in their click codas, suggesting a far more complex communication system than previously understood. “It was striking just how structured the system was. I’ve never seen anything like that before with other animals,” Begus, a UC Berkeley linguistics professor and the linguistics lead at Project CETI, told SFGATE. “We’re showing the world that there’s more than meets the eye in sperm whales and that, if one cares to look closely, they’re not as alien. We’re much more similar to each other than we used to think.” SFGATE reports: With the help of a machine-learning model to identify patterns, Begus and his team combed through recordings collected from social units of sperm whales off the coast of the island of Dominica between 2005 and 2018. When they sped up the audio, removing the silences between clicks, they heard new patterns. They found acoustic properties that share similarities with two vowels — a and i — and several vowel combinations.

“Before, people were looking just at the timing and the number of clicks exchanged between sperm whales, but now we have to look at the frequencies, too. A whole new set of patterns have appeared,” Begus said. “Now, it’s one of the most complex non-human communication systems we have observed.” […] Begus said the research only shows how much more we have to learn about whales’ style of communicating. He is particularly interested in exploring how the system may differ for whales between regions and how whale babies learn to communicate in this way. Most importantly, he wants to understand the meaning behind the sounds, as a “window into whale thoughts and lives.” The research was published in the journal Open Mind.

An anonymous reader quotes a report from the New York Times: For the first time, scientists are tracking the migration of monarch butterflies across much of North America, actively monitoring individual insects on journeys from as far away as Ontario all the way to their overwintering colonies in central Mexico. This long-sought achievement could provide crucial insights into the poorly understood life cycles of hundreds of species of butterflies, bees and other flying insects at a time when many are in steep decline.

The breakthrough is the result of a tiny solar-powered radio tag that weighs just 60 milligrams and sells for $200. Researchers have tagged more than 400 monarchs this year and are now following their journeys on a cellphone app created by the New Jersey-based company that makes the tags, Cellular Tracking Technologies. Most monarchs weigh 500 to 600 milligrams, so each tag-bearing migrator making the transcontinental journey is, by weight, equivalent to a half-raisin carrying three uncooked grains of rice.

Researchers are tracking more than 400 tagged monarch butterflies as they fly toward winter colonies in central Mexico. The maps [in the article] follow six butterflies. […] Tracking the world’s most famous insect migration may also have a big social impact, with monarch lovers able to follow the progress of individual butterflies on the free app, called Project Monarch Science. Many of the butterflies are flying over cities and suburbs where pollinator gardens are increasingly popular. Some tracks could even lead to the discovery of new winter hideaways. “There’s nothing that’s not amazing about this,” said Cheryl Schultz, a butterfly scientist at Washington State University and the senior author of a recent study documenting a 22 percent drop in butterfly abundance in North America over a recent 20-year period. “Now we will have answers that could help us turn the tide for these bugs.”

alternative_right shares a report from ScienceAlert: A new study from researchers in Australia reveals that the people who never forget faces look “smarter, not harder.” In other words, they naturally focus on a person’s most distinguishing facial features. “Their skill isn’t something you can learn like a trick,” explains lead author James Dunn, a psychology researcher at the University of New South Wales (UNSW) Sydney. “It’s an automatic, dynamic way of picking up what makes each face unique.”

To see what super-recognizers see, Dunn and his colleagues used eye-tracking technology to reconstruct how people surveyed new faces. They did this with 37 super-recognizers and 68 people with ordinary facial recognition skills, noting where and for how long participants looked at pictures of faces displayed on a computer screen. The researchers then fed the data into machine learning algorithms trained to recognize faces. The algorithms, a type known as deep neural networks, were tasked with deciding if two faces belonged to the same person. “These findings suggest that the perceptual foundations of individual differences in face recognition ability may originate at the earliest stages of visual processing — at the level of retinal encoding,” Dunn and colleagues write in their paper.

The findings have been published in the journal Proceedings of the Royal Society B: Biological Sciences.

Chinese automakers are rapidly expanding across South America, boosted by the new Chinese-built Port of Chancay, aggressive pricing, local partnerships, and growing regional demand. Reuters reports: China has been ramping up sales since the opening last year of the Port of Chancay, north of Lima. The Chinese-built megaport has halved trans-Pacific shipping times just as Chinese manufacturers face rising barriers to entry in the United States and greater trade restrictions in Europe.

BYD, which makes EVs, plug-in hybrids and combustion engine cars, plans to open a fourth dealership in Lima by the end of this year, while Chery and Geely have more than a dozen in total in Peru. Chinese carmakers face a profit-destroying price war at home and a growing surplus of new cars rolling out of Chinese factory lines. Much of this excess is being shipped overseas to the Middle East, Central Asia and Latin America, according to global automotive analyst Felipe Munoz at JATO Dynamics.

The Chinese have “carved out space,” across both electric and petrol-powered cars, said Martin Bresciani, president of Chile’s automotive business chamber, CAVEM. “The Chinese have already demonstrated that they match global standards in quality.” Chinese brands reached 29.6% of all new passenger car sales in Chile in the first quarter of this year. […] Part of China’s success has been partnering with trusted local importers to offer more affordable models tailored to regional tastes, according to seven dealerships Reuters spoke to in Peru, Chile, Uruguay and Argentina.

Because ‘Black Mirror’ was actually just a regular mirror all along, AI app 2wai (pronounced 2-way) creates digital avatars that you can interact with, promising to connect the currently living with the currently dead for a monthly fee. Because that’s something we’ve been needing. Allegedly all that’s needed is a 3-minute video of the source human to create an AI clone. But what can it do if I only have a 10-second video, some doodles, and me throwing my voice? Since this video’s release, the app has been met with some hostility, presumably, at last from what I’ve been able to gather, because it deserves to be.

Even after disabling remote control and officially ending support for early Nest Learning Thermostats, Google is still receiving detailed sensor and activity data from these devices, including temperature changes, motion, and ambient light. The Verge reports: After digging into the backend, security researcher Cody Kociemba found that the first- and second-generation Nest Learning Thermostats are still sending Google information about manual temperature changes, whether a person is present in the room, if sunlight is hitting the device, and more. Kociemba made the discovery while participating in a bounty program created by FULU, a right-to-repair advocacy organization cofounded by electronics repair technician and YouTuber Louis Rossmann.

FULU challenged developers to come up with a solution to restore smart functionality to Nest devices no longer supported by Google, and that’s exactly what Kociemba did with his open-source No Longer Evil project. But after cloning Google’s API to create this custom software, he started receiving a trove of logs from customer devices, which he turned off. “On these devices, while they [Google] turned off access to remotely control them, they did leave in the ability for the devices to upload logs. And the logs are pretty extensive,” Kociemba tells The Verge. […] “I was under the impression that the Google connection would be severed along with the remote functionality, however that connection is not severed, and instead is a one-way street,” Kociemba says.

An anonymous reader quotes a report from Security Affairs: On October 24, 2025, Azure DDoS Protection detected and mitigated a massive multi-vector attack peaking at 15.72 Tbps and 3.64 billion pps, the largest cloud DDoS ever recorded, aimed at a single Australian endpoint. Azure’s global protection network filtered the traffic, keeping services online. The attack came from the Aisuru botnet, a Turbo Mirai-class IoT botnet using compromised home routers and cameras.

The attack used massive UDP floods from more than 500,000 IPs hitting a single public address, with little spoofing and random source ports that made traceback easier. It highlights how attackers are scaling with the internet: faster home fiber and increasingly powerful IoT devices keep pushing DDoS attack sizes higher. “On October 24, 2025, Azure DDOS Protection automatically detected and mitigated a multi-vector DDoS attack measuring 15.72 Tbps and nearly 3.64 billion packets per second (pps). This was the largest DDoS attack ever observed in the cloud and it targeted a single endpoint in Australia,” reads a report published by Microsoft. “The attack originated from Aisuru botnet.”

“Attackers are scaling with the internet itself. As fiber-to-the-home speeds rise and IoT devices get more powerful, the baseline for attack size keeps climbing,” concludes the post. “As we approach the upcoming holiday season, it is essential to confirm that all internet-facing applications and workloads are adequately protected against DDOS attacks.”
