Complex brain activity detected in dying patients

The study, led by Jimo Borjigin, associate professor of molecular and integrative physiology and neurology at Michigan, was very small, featuring only four patients. But the findings echo animal model studies, where the presence of gamma waves in dying brains has also been observed, including in a previous study in rats that Borjigin and colleagues ran a decade earlier.


“These data demonstrate that the surge of gamma power and connectivity observed in animal models of cardiac arrest can be observed in select patients during the process of dying,” the researchers wrote in their paper, published in PNAS.

What are gamma waves? Gamma waves are high-frequency brain waves researchers believe represent multiple areas of the brain working together in complex thoughts. Take, for example, combining the sight, sound, and smell of a car to get a full picture of the vehicle, Ajmal Zemmar, a neurosurgeon at the University of Louisville uninvolved with the study, told Science.

Researchers have also found patterns of gamma waves in healthy people while dreaming, learning, and recalling lessons, Science reported, with some researchers associating them with consciousness itself. But the exact mechanisms behind gamma waves are “one of the biggest mysteries in neuroscience,” Zemmar said.

Neural Implant Translates Brainwaves Into Words

Summary: A new speech prosthetic offers hope for those with speech-impairing neurological disorders.

By converting brain signals into speech using high-density sensors and machine learning, the technology represents a significant advancement over current slower communication aids.

Though still in early stages, the device has achieved a 40% accuracy in decoding spoken data during limited trials and is moving towards a cordless design.

AI Pioneer Kai-Fu Lee Builds $1 Billion Startup in Eight Months

01. AI’s model outperforms Meta’s Llama 2 on certain metricsStartup to offer open-source model; proprietary options laterA Chinese startup founded by computer scientist Kai-Fu Lee has become a unicorn in less than eight months on the strength of a new open-source artificial-intelligence model that outstrips Silicon Valley’s best, on at least certain metrics.

The company, 01.AI, has reached a valuation of more than $1 billion after a funding round that included Alibaba Group Holding Ltd.’s cloud unit, Lee said in an interview. The chief executive officer of venture firm Sinovation Ventures will also be CEO of the new startup. He began assembling the team for 01.AI in March and started… More.

Chatbots May ‘Hallucinate’ More Often Than Many Realize

When summarizing facts, ChatGPT technology makes things up about 3 percent of the time, according to research from a new start-up. A Google system’s rate was 27 percent.

When the San Francisco start-up OpenAI unveiled its ChatGPT online chatbot late last year.

When Google introduced a similar chatbot several weeks later, it spewed nonsense about the James Webb telescope. The next day, Microsoft’s new Bing chatbot offered up all sorts of bogus information about the Gap, Mexican nightlife and the… More.

Micron taps Taiwan and Japan to make advanced AI memory chips

TAICHUNG, Taiwan — U.S. memory chip maker Micron is doubling down on Taiwan and Japan as the key production bases for its cutting-edge products as it battles South Korean rivals to capture demand from the AI boom.

Taiwan and Japan play vital roles in the production of Micron’s most advanced dynamic random-access (DRAM) memory and high-bandwidth memory (HBM) chips, Naga Chandrasekaran, Micron’s senior vice president of technology development, told reporters on Monday. Advanced DRAM and HBM chips are vital for enabling powerful generative AI computing applications such as ChatGPT and Bard.

The Vital Role Of Partnerships In Scaling Artificial Intelligence

An effective way of tackling this challenge is to find friendly partners who can help bear the burden. This means other businesses and organizations with the skills you’re missing or that specialize in the support infrastructure you need, be it in engineering, logistics, marketing or sales.

This is particularly essential when dealing with AI. It’s certainly getting easier for companies to start exploring and benefiting from AI. But fully integrating it in a business across every viable use case is still expensive, time-consuming and often dependent on the availability of highly skilled specialists.

Businesses rely on trusted networks of consultants, suppliers, and resellers to create these partnership ecosystems. Partnership working in the context of AI is going to be particularly important for small and medium sized enterprises (SMEs) that generate the majority of GDP and account for 90 percent of global business activity. Ultimately, it’s likely to be these businesses that will determine whether AI achieves its projected $4.4 trillion potential.

AI-chip cousins? CEO Nvidia, AMD lead US tech war against China

Jensen Huanf and Lisa Lu, CEOs of NVIDIA and AMD, are cousins. However, they are not close and have not been seen out together publicly.

Those who keep abreast of what’s happening in the semiconductor industry know that top dogs NVIDIA and AMD are competitors that regularly take potshots at each other. But what a lot of people may not know is that the CEOs of these two companies are cousins.

Toyota’s EVs Aim To Win With 620 Miles Of Range, But Not Big Batteries

Awkward name aside, the Lexus LF-ZC Concept that debuted at the Japan Mobility Show last week is a very big deal. When it goes into production in 2026, it will be the first electric vehicle on an all-new, ground-up Toyota platform; will do some very next-level things with the company’s steer-by-wire technology; and an alleged 620 miles of electric range.

It is not, however, going to do that with some huge battery pack that weighs as much as an apartment building. Instead, it’s going to rely mostly on chemistry to deliver on those big range claims.

As part of the auto show festivities, Toyota invited several international media outlets, including InsideEVs, to Japan last week. There, the world’s largest automaker previewed a number of emerging technology concepts, including a simulated “manual transmission” for electric cars, an advanced in-car AI assistant and its EV battery plans for the next few years.

Tesla to integrate Elon Musk’s new AI assistant in its vehicles

Tesla is going to integrate Elon Musk’s newly launched Grok AI assistant in its electric vehicles, according to the CEO.

Earlier this year, Musk launched a new AI startup, xAI, and said that it will work closely with Tesla.

The company’s mission is “to understand the true nature of the universe”, but in practice, its first project is to build a chatbot or AI assistant à la ChatGPT.
