Li-Fi: The Networking Standard That Could Change Wireless

Posted by in category: internet

It would probably be an understatement to say that Li-Fi players everywhere must be thrilled with the recent ratification of the light-based wireless communications standard, IEEE 802.11bb. The certification provides a globally recognized framework to deploy Li-Fi technologies and sets the stage for Li-Fi systems to interoperate with Wi-Fi networks, each of which should trigger faster technology adoption. And for Li-Fi users, the standard opens the door to eye-watering data speeds of up to 224 Gbps, way faster than even the 40-Gbps data rates promised by next-generation Wi-Fi 7.

Li-Fi is a wireless technology that uses light rather than radio frequencies to transmit data. It was first… More.

“In my view, the impact of the new standard will be huge,” said Harald Haas, Li-Fi pioneer, chief scientific officer of pureLiFi and professor of mobile communications at the University of Strathclyde, U.K. “We’ve truly opened up wireless communications in the optical domain, which is a big step.”

Physicists Achieve Net Energy Gain in a Fusion Reaction for the Second Time

Posted by in categories: innovation, particle physics

Fusion power has long been seen as a pipe dream, but in recent years the technology has appeared to be edging closer to reality. The second demonstration of a fusion reaction that creates more power than it uses is another important marker suggesting fusion’s time may be coming.

Generating power by smashing together atoms holds considerable promise, because the fuel is abundant, required in tiny amounts, and the reactions produce little long-lived radioactive waste and no carbon emissions. The problem is that initiating fusion typically uses much more energy than the reaction generates, making a commercial fusion plant a distant dream at present.

Last December though, scientists at the Lawrence Livermore National Laboratory made a major breakthrough when they achieved “fusion ignition” for the first time. The term refers to a fusion reaction that produces more energy than was put in and becomes self-sustaining.

Arithmetic Has a Biological Origin—It’s an Expression in Symbols of the ‘Deep Structure’ of Our Perception

Posted by in categories: biological, mathematics

By stepping outside the box of our usual way of thinking about numbers, my colleagues and I have recently shown that arithmetic has biological roots and is a natural consequence of how perception of the world around us is organized.

Our results explain why arithmetic is true and suggest that mathematics is a realization in symbols of the fundamental nature and creativity of the mind.

Thus, the miraculous correspondence between mathematics and physical reality that has been a source of wonder from the ancient Greeks to the present—as explored in astrophysicist Mario Livio’s book Is God a Mathematician?—suggests the mind and world are part of a common unity.

Battery Scientists Claim Breakthrough, 10-Minute Fast Charging For 1,500 Cycles

Posted by in categories: Elon Musk, sustainability, transportation

Long charging times and limited access to fast chargers can be the dealbreakers for electric vehicle buyers today. But technology advancements are often fast-paced, and it’s hard to predict how close, or far, we are from the next big breakthrough. However, battery scientists at Oak Ridge National Laboratory (ORNL) might have a solution for charging speeds.

ORNL’s paper highlights a new lithium-ion battery that can not only recharge to 80 percent in 10 minutes but also sustain the fast charging ability for 1,500 cycles. For those new to the EV language, battery charge, and discharge occur when ions travel between the positive and negative electrodes through a medium called an electrolyte.

Getting to fifteen hundred charging cycles isn’t a new development. Tesla CEO Elon Musk tweeted in 2019 that the Model 3’s battery modules were designed to last 1,500 cycles or between 300,000 and 500,000 miles.

Google’s New Gmail Tool Is Hallucinating Emails That Don’t Exist

Posted by in categories: mapping, robotics/AI

Google’s new Bard extension will apparently summarize emails, plan your travels, and — oh, yeah — fabricate emails that you never actually sent.

Last week, Google plugged its large language model-powered chatbot called Bard into a bevy of Google products including Gmail, Google Drive, Google Docs, Google Maps, and the Google-owned YouTube, among other apps and services. While it’s understandable that Google would want to marry its newer generative AI efforts with its already-established product lineup, it seems that Google might have moved a little too fast.

According to New York Times columnist Kevin Roose, Bard isn’t the helpful inbox assistant that Google apparently wants it to be — at least yet. In his testing, says Roose, the AI hallucinated entire email correspondences that never took place.
