Ah, cats. We love our furry feline overlords despite the occasional hairball and their propensity to scratch the furniture to sharpen their claws. The latter is perfectly natural kitty behavior, but overly aggressive scratching is usually perceived as a behavioral problem. Veterinarians frown on taking extreme measures like declawing or even euthanizing such "problematic" cats. But there are alternative science-backed strategies for reducing or redirecting the scratching the behavior, according to the authors of a new paper published in the journal Frontiers in Veterinary Science.

This latest study builds on the group's prior research investigating the effects of synthetic feline facial pheromones on undesirable scratching in cats, according to co-author Yasemin Salgirli Demirbas, a veterinary researcher at Ankara University in Turkey. "From the beginning, our research team agreed that it was essential to explore broader factors that might exacerbate this issue, such as those influencing stress and, consequently, scratching behavior in cats," she told Ars. "What’s new in this study is our focus on the individual, environmental and social dynamics affecting the level of scratching behavior. This perspective aims to enhance our understanding of how human and animal welfare are interconnected in different scenarios."

The study investigated the behavior of 1,211 cats, with data collected via an online questionnaire completed by the cats' caregivers. The first section collected information about the caregivers, while the second asked about the cats' daily routines, social interactions, environments, behaviors, and temperaments. The third and final section gathered information about the frequency and intensity of undesirable scratching behavior in the cats based on a helpful "scratching index."

On the day before Christmas last year, a Falcon 9 rocket launched from California and put two spy satellites into low-Earth orbit for the armed forces of Germany, which are collectively called the Bundeswehr.

Initially, the mission appeared successful. The German satellite manufacturer, OHB, declared that the two satellites were "safely in orbit." The addition of the two SARah satellites completed a next-generation constellation of three reconnaissance satellites, the company said.

However, six months later, the two satellites have yet to become operational. According to the German publication Der Spiegel, the antennas on the satellites cannot be unfolded. Engineers with OHB have tried to resolve the issue by resetting the flight software, performing maneuvers to vibrate or shake the antennas loose, and more to no avail.

In December, New York became the first state to enact a "Right to Repair" law for electronics. Since then, other states, including Oregon and Minnesota, have passed similar laws. However, a recent analysis of some recently released gadgets shows that self-repair still has a long way to go before it becomes ubiquitous.

On Monday, the US Public Interest Research Group (PIRG) released its Leaders and Laggards report that examined user repairability of 21 devices subject to New York's electronics Right to Repair law. The nonprofit graded devices "based on the quality and accessibility of repair manuals, spare parts, and other critical repair materials.”

Nathan Proctor, one of the report's authors and senior director for the Campaign for the Right to Repair for the US PIRG Education Fund, told Ars Technica via email that PIRG focused on new models since the law only applies to new products, adding that PIRG "tried to include a range of covered devices from well-known brands."

Human Rights Watch (HRW) continues to reveal how photos of real children casually posted online years ago are being used to train AI models powering image generators—even when platforms prohibit scraping and families use strict privacy settings.

Last month, HRW researcher Hye Jung Han found 170 photos of Brazilian kids that were linked in LAION-5B, a popular AI dataset built from Common Crawl snapshots of the public web. Now, she has released a second report, flagging 190 photos of children from all of Australia’s states and territories, including indigenous children who may be particularly vulnerable to harms.

These photos are linked in the dataset "without the knowledge or consent of the children or their families." They span the entirety of childhood, making it possible for AI image generators to generate realistic deepfakes of real Australian children, Han's report said. Perhaps even more concerning, the URLs in the dataset sometimes reveal identifying information about children, including their names and locations where photos were shot, making it easy to track down children whose images might not otherwise be discoverable online.
