AI-Trained Surgical Robot Removes Pig Gallbladders Without Any Human Help An anonymous reader quotes a report from The Guardian: Automated surgery could be trialled on humans within a decade, say researchers, after an AI-trained robot armed with tools to cut, clip and grab soft tissue successfully removed pig gall bladders without human help. The robot surgeons were schooled on video footage of human medics conducting operations using organs taken from dead pigs. In an apparent research breakthrough, eight operations were conducted on pig organs with a 100% success rate by a team led by experts at Johns Hopkins University in Baltimore in the US. [...]
The technology allowing robots to handle complex soft tissues such as gallbladders, which release bile to aid digestion, is rooted in the same type of computerized neural networks that underpin widely used artificial intelligence tools such as Chat GPT or Google Gemini. The surgical robots were slightly slower than human doctors but they were less jerky and plotted shorter trajectories between tasks. The robots were also able to repeatedly correct mistakes as they went along, asked for different tools and adapted to anatomical variation, according to a peer-reviewed paper published in the journal Science Robotics. The authors from Johns Hopkins, Stanford and Columbia universities called it "a milestone toward clinical deployment of autonomous surgical systems." [...]
In the Johns Hopkins trial, the robots took just over five minutes to carry out the operation, which required 17 steps including cutting the gallbladder away from its connection to the liver, applying six clips in a specific order and removing the organ. The robots on average corrected course without any human help six times in each operation. "We were able to perform a surgical procedure with a really high level of autonomy," said Axel Krieger, assistant professor of mechanical engineering at Johns Hopkins. "In prior work, we were able to do some surgical tasks like suturing. What we've done here is really a full procedure. We have done this on eight gallbladders, where the robot was able to perform precisely the clipping and cutting step of gallbladder removal without any human intervention. "So I think it's a really big landmark study that such a difficult soft tissue surgery is possible to do autonomously." Currently, nearly all of the NHS's 70,000 annual robotic surgeries are human-controlled, but the UK plans to expand robot-assisted procedures to 90% within the next decade.

Google Nerfs Second Pixel Phone Battery This Year An anonymous reader quotes a report from Ars Technica: For the second time in a year, Google has announced that it will render some of its past phones almost unusable with a software update, and users don't have any choice in the matter. After nerfing the Pixel 4a's battery capacity earlier this year, Google has now confirmed a similar update is rolling out to the Pixel 6a. The new July Android update adds "battery management features" that will make the phone unusable. Given the risks involved, Google had no choice but to act, but it could choose to take better care of its customers and use better components in the first place. Unfortunately, a lot more phones are about to end up in the trash. [...]
Pixel 4a units contained one of two different batteries, and only the one manufactured by a company called Lishen was downgraded. For the Pixel 6a, Google has decreed that the battery limits will be imposed when the cells hit 400 charge cycles. Beyond that, the risk of fire becomes too great -- there have been reports of Pixel 6a phones bursting into flames. Clearly, Google had to do something, but the remedies it settled on feel unnecessarily hostile to customers. It had a chance to do better the second time, but the solution for the Pixel 6a is more of the same. [...]
When Google killed the Pixel 4a's battery life, it offered a few options. You could have the battery replaced for free, get $50 cash, or accept a $100 credit in the Google Store. However, claiming the money or free battery was a frustrating experience that was rife with fees and caveats. The store credit is also only good on phones and can't be used with other promotions or discounts. And the battery swap? You'd better hope there's nothing else wrong with the device. If it has any damage, like cracked glass, it may not qualify for a free battery replacement.
Now we have the Pixel 6a Battery Performance Program with all the same problems. Pixel 6a owners can get $100 in cash or $150 in store credit. Alternatively, Google offers a free battery replacement with the same limits on phone condition. This is all particularly galling because the Pixel 6a is still an officially supported phone, with its final guaranteed update coming in 2027. Google also pulled previous software packages for this phone to prevent rollbacks. [...] If you have a Pixel 6a, the battery-killing update is rolling out now. You'll have no choice but to install it if you want to remain on the official software. Google has a support site where you can try to get a free battery swap or some cash.
