Google’s new technique works by sending low-intensity ultrasonic probing signals via the speakers.

Researchers at Google have devised a technology that allows active noise-canceling (ANC) wearables to feature health-sensing applications.

The team utilized a technique called audio plethysmography (APG) in ANC wearables to monitor a user’s physiological data, such as heart rate and heart rate variability, without the need for additional sensors or sacrificing battery life.

“This is significant because it creates the opportunity for greater renewable energy storage.”

Through the use of solar collectors, concentrated solar thermal technology (CST) harnesses solar energy to produce heat or electricity. The process is simple although difficult to execute successfully: large mirrors or lenses focus sunlight onto a narrow region known as the receiver.

These mirrors are what are known as solar collectors and they come in a variety of formats each with a distinct design and focusing technique, such as dish systems, solar power towers, and parabolic troughs.

The researchers built a dynamic data acquisition platform to capture human arm motion during assembly tasks.

A team of researchers from the Beijing Institute of Technology has developed a new method to control robots that can assemble satellites in space. The technique is inspired by the human arm, which can adjust its damping to perform different tasks with precision and stability. The researchers published their findings in Cyborg and Bionic Systems.

ChatGPT, the AI-powered chatbot from OpenAI, far outpaces all other AI chatbot apps on mobile devices in terms of downloads and is a market leader by revenue, as well. However, it’s surprisingly not the top AI app by revenue — several photo AI apps and even other AI chatbots are actually making more money than ChatGPT, despite the latter having become a household name for an AI chat experience.

Since its launch on mobile devices in May of this year, ChatGPT’s downloads and revenue have continued to grow. In its first month, when the app was available on iOS only, it topped 3.9 million downloads, which grew to 15.1 million by June, according to an analysis of the AI app market by Apptopia. Then, following a slight dip in July, ChatGPT grew again to top 23 million downloads as of September 2023.

In addition, ChatGPT’s usage on mobile devices has similarly grown from just over 1.34 million monthly active users in May to now 38.88 million as of September.

The pioneering AI researcher and activist shares her personal journey in a new book, and explains her concerns about today’s AI systems.

Joy Buolamwini, the renowned AI researcher and activist, appears on the Zoom screen from home in Boston, wearing her signature thick-rimmed glasses.

As an MIT grad, she seems genuinely interested in seeing old covers of MIT Technology Review that hang in our London office. An edition of the magazine from 1961 asks: “Will your son get into college?”

While European nations are ahead on dimensions like equality, social progress, and climate change redressal, they lack technological advancements in comparison to the United States. The European region, including the UK, still lacks the investment and culture necessary for a startup ecosystem prevalent in California’s Silicon Valley.

The Valley is a globally recognized hub for technology and innovation. Many of the world’s leading technology companies, like Apple, Google, Facebook, and Amazon, are based there. However, Europe also has notable… More.

Silicon Valley overshadows the EU in tech, but with the advent of new-age artificial intelligence, Europe’s leading entrepreneurs think it could offer the Euro startup ecosystem to be a key player in the race.

Travis Gienger is a talented gourd-grower, and he’s used to earning accolades for his colossal pumpkins. Since 2020, he’s won three of the past four World Championship Pumpkin Weigh-Off competitions—and this year’s entry topped them all. Weighing in at 2,749 pounds, Gienger’s gourd has set a new world record for the heaviest pumpkin.

Nicknamed “Michael Jordan,” the pumpkin took the crown during the annual championship in Half Moon Bay, California, this week, reports Heidi Raschke of Minnesota Public Radio (MPR). It easily beat out last year’s champion—Gienger’s own 2,560-pounder, which set a new North American record and which he later turned into the world’s largest jack o’lantern.

“I was not expecting that. It was quite the feeling,” says Gienger, a 43-year-old landscape and horticulture teacher at Anoka Technical College, to the Associated Press (AP). He has been growing pumpkins since he was a teenager, following in the footsteps of his father.

Whenever measurement precision nears the uncertainty limit set by quantum mechanics, the results become dependent on the interaction dynamics between the measuring device and the system. This finding may explain why quantum experiments often produce conflicting results and may contradict basic assumptions regarding physical reality.

Two quantum physicists from Hiroshima University recently analyzed the dynamics of a measurement interaction, where the value of a physical property is identified with a quantitative change in the meter state. This is a difficult problem, because quantum theory does not identify the value of a physical property unless the system is in a so-called “eigenstate” of that physical property, a very small set of special quantum states for which the physical property has a fixed value.

The researchers solved this fundamental problem by combining information about the past of the system with information about its future in a description of the dynamics of the system during the measurement interaction, demonstrating that the observable values of a physical system depend on the dynamics of the measurement interaction by which they are observed.
