Chip designer Nvidia Corp on Wednesday said that U.S. officials told it to stop exporting two top computing chips for artificial intelligence work to China, a move that could cripple Chinese firms' ability to carry out advanced work like image recognition and hamper a business Nvidia expects to generate $400 million in sales this quarter. Nvidia shares fell 4% after hours. The company said the ban, which affects its A100 and H100 chips designed to speed up machine learning tasks, could interfere with completion of developing the H100, the flagship chip Nvidia announced this year. Shares of Nvidia rival Advanced Micro Devices were down 2% after hours. An AMD spokesman told Reuters it had received new license requirements that will stop its MI250 artificial intelligence chips from being exported to China but it believes its MI100 chips will not be affected.

A gearbox driven by an external magnetic field can power tiny but powerful robots that crawl like a caterpillar or jump almost 40 times their own height, despite having no batteries or motors on board. The technology could lead to medical robots that can travel through the human body, taking samples or delivering drugs. Soft robots – which have no batteries, motors or electronics and are powered and controlled remotely by light or magnets – are a popular field of research because their simplicity enables them to be highly miniaturised. But they may be lacking in power when the task requires puncturing skin or opening collapsed cavities. Now, Chong Hong at the Max Planck Institute for Intelligent Systems in Germany and his colleagues have created a gearbox that measures around 3 millimetres across and is equipped with cogs as small as 270 micrometres in diameter.

Since 2016, Tesla has been marketing an expensive option called Full Self-Driving. A reasonable person might infer from the name that the software package enables a car to drive itself, fully. No car available for consumers to buy is capable of full self-driving. The California Department of Motor Vehicles has rules on its books that ban the advertisement of cars as "self-driving" when they are not. But it has never enforced those rules.

Robotaxi safety operator is an occupation that exists only in our time, the result of an evolving technology that's advanced enough to get rid of a driver--most of the time, and in controlled environments--but not good enough to convince authorities that they can do away with human intervention altogether. Today, self-driving companies from the US, Europe, and China are racing to bring the technology to commercial application. Most of them, including Apollo, the self-driving arm of Baidu, have started on-demand robotaxi trials on public roads but still need to operate with various constraints. With an associate degree in human resources, Liu has no academic training related to this job, But he has always loved driving, and he acted as the driver for his boss in a previous role. When he heard about the self-driving technologies, his curiosity pushed him to look up related jobs online and apply.

The Mohajer-6 has the capability to carry out surveillance and reconnaissance missions, and the Shahed series is considered among the most capable of Iran's military drones, according to comments made by the Iranian military to local news media. Iran is a pioneer in drone technology, with at least four decades of design and manufacturing experience, and it has been providing combat drones to military groups and proxy militia in Yemen, Iraq, Syria, Lebanon and Gaza. Officials in Israel, the United States and some Sunni Arab countries like Saudi Arabia have said they are increasingly concerned that Iran's advancing drone technology could destabilize the region and empower militias backed by Iran. In the shadow war between Iran and Israel, Iranian drones have been involved in attacks on ships and have targeted U.S. military bases in Iraq and Syria. Israel has also attacked a secret facility in western Iran where hundreds of drones were believed to have been stored.

"While technology analysis is still new, it can provide some of the needed foundations for technology as a field of its own and answer such questions as'Can AI invent?.'" Not long ago, Dr. Stephen Thaler, a member of the scientific community, began claiming that his artificial intelligence (AI) machine, DABUS, was a bona fide inventor. The outcome so far has been that the claim has been rejected in most jurisdictions. A notable exception is South Africa, which accepted Thaler's patent application under "Formalities Examination" with DABUS as named inventor. The acceptance of the patent in South Africa and the evolution of the legal field opens the possibility of further assertions and challenges with respect to AI inventorship.

With the uptake of electric vehicles (EVs) increasing across the automotive market, there is a need to ensure optimized function and reliability of the battery that is powering the vehicle. Across many industries and markets, lithium-ion (Li-ion) batteries are crucial components of devices and machinery, including smartphones, solar power storage, and power supplies. Thus, maintaining good battery health is absolutely vital in today's world. Now, a group of researchers from the University of Cambridge has recently developed a new algorithm that uses machine learning to help preserve good battery health in EVs. The algorithm is able to use pattern recognition and predictability models to see how various driving styles influence the performance of the vehicle's battery.

Earlier this year, Google unveiled AI Test Kitchen -- an Android app that lets users talk to one of its most advanced AI chatbots, LaMDA 2. Today, the company is opening up registrations for early access. You can sign up here, and Google says it will soon be letting people download the app and start chatting. It's interesting, considering that Meta made an almost identical move just earlier this month, opening up its latest and greatest AI chatbot, BlenderBot 3, for public consumption. Of course, people quickly found that they could get BlenderBot to say creepy or untruthful things (or even criticize the bot's nominal boss, Mark Zuckerberg), but that's kind of the whole point of releasing these demos. As Mary Williamson, a research engineering manager at Facebook AI Research (FAIR), told me at the beginning of the month, many companies don't like to test their chatbots in the wild because what they say will be damaging to the company, as with Microsoft's Tay.
