Hybrid RF-VLC system could reduce power consumption in wireless networks

Posted by in categories: computing, internet

Wireless internet supports the daily activities of countless people worldwide, ranging from their professional communications to internet browsing and the streaming of movies or TV series. This spiking demand for wireless internet access goes hand in hand with greater power consumption, which in turn contributes to carbon emissions worldwide.

Future wireless networks should be able to support the high computational demands of many modern applications and internet services, while limiting power consumption. Some researchers have thus been developing energy efficient techniques supporting between devices and the sharing of media or other information online.

One of these solutions is known as communication (VLC). This is a method to realize efficient wireless communication using visible light to transmit data, relying on (LEDs) or other artificial light sources.

These Living Computers Are Made from Human Neurons

Posted by in categories: bioengineering, biological, internet, robotics/AI

In the search for less energy-hungry artificial intelligence, some scientists are exploring living computers.

By Jordan Kinard

Artificial intelligence systems, even those as sophisticated as ChatGPT, depend on the same silicon-based hardware that has been the bedrock of computing since the 1950s. But what if computers could be molded from living biological matter? Some researchers in academia and the commercial sector, wary of AI’s ballooning demands for data storage and energy, are focusing on a growing field known as biocomputing. This approach uses synthetic biology, such as miniature clusters of lab-grown cells called organoids, to create computer architecture. Biocomputing pioneers include Swiss company FinalSpark, which earlier this year debuted its “Neuroplatform”—a computer platform powered by human-brain organoids—that scientists can rent over the Internet for $500 a month.

Nanoharvesting unused signals such as Wi-Fi Into energy for electronics

Posted by in categories: energy, internet, nanotechnology

We are constantly surrounded by electromagnetic waves such as Wi-Fi and Bluetooth signals. What if we could turn the unused excess into usable energy? Researchers at Tohoku University, the National University of Singapore, and the University of Messina developed a novel technology to efficiently harvest ambient low-power radiofrequency (RF) signals into direct-current (DC) power. This ‘rectifier’ technology can be easily integrated into energy harvesting modules to power electronic devices and sensors, enabling battery-free operation.

The results were published in Nature Electronics (“Nanoscale spin rectifiers for harvesting ambient radiofrequency energy”).

SpaceX’s new direct-to-cell Starlink satellites are way brighter than the originals

Posted by in categories: chemistry, internet, policy, space, sustainability

Even if we can dodge a disaster in orbit by responsibly de-orbiting derelict satellites, many scientists are concerned that the number of objects circling our planet could still do harm: When they deorbit, they could deposit a significant flux of metals that could alter the chemical makeup of Earth’s atmosphere.

“Effects on astronomy are just the tip of the iceberg,” said Barentine, who says we may be fast approaching a turning point where tragedy becomes imminent, either in space due to a collision or on the ground from falling debris. “Space policy-making moves far too slowly to effectively deal with all of this.”

“Right now, there’s not a lot to look forward to that is positive,” he added. “If the New Space Age goes badly in the end, history will not look favorably on it.”

Epilepsy is first use case for eyelid wearable

Posted by in categories: energy, health, internet, wearables

The wearables market has been dominated, so far, by smartwatches and fitness trackers. The first Apple Watch was launched in April 2015, and wearable technology now includes jewelry that tracks your steps and notifies you of an incoming call, VR headsets for gamers, earbuds, smart glasses with Internet access, smart clothing integrated with electronic devices and a range of health monitors.

But the world’s first eyelid wearable device opens up a whole new world of opportunity.

Blink Energy’s device weighs just 0.4 grams (0.014 ounces) — less than half the weight of a paperclip – and is fitted to one eyelid. You barely notice it, says Bar-On. “After two minutes you forget it’s there.”

Physicists develop new method to combine conventional internet with the quantum internet

Posted by in categories: internet, quantum physics

“To make the a reality, we need to transmit entangled photons via fiber optic networks,” says Prof. Dr. Michael Kues, Head of the Institute of Photonics and Board Member of the PhoenixD Cluster of Excellence at Leibniz University Hannover.

“We also want to continue using optical fibers for conventional data transmission. Our is an important step to combine the conventional internet with the quantum internet.”

In their experiment, the researchers demonstrated that the entanglement of photons is maintained even when they are sent together with a laser pulse. The research results were published in Science Advances.

DARPA Funded Research Shows Advances in Powering Robot Spy Bugs with Ocean Bacteria

Posted by in categories: government, internet, military, robotics/AI, space, surveillance

A new robot bug that can live in the ocean for 100 years and feed off of bacteria has made its debut as DARPA’s latest surveillance tool.

With a vast amount of area to cover, the US government is funding research for new oceanic spy technology. Now, a Binghamton University team has developed what may become one of the most simple and effective tools in its arsenal.

Now, a new DARPA initiative is playing off of the idea of “the Internet of Things,” the term used for the many non-computer devices connected to the Internet in some way, from refrigerators to fish tanks, and seeking to develop an “Ocean of Things.” With many futurists’ eyes on space conflict and satellite warfare, it’s easy to forget that 71% of the Earth’s surface is water, and naval conflict is still an element in geopolitics.

OpenAI Has Software That Detects AI Writing With 99.9 Percent Accuracy, Refuses to Release It

Posted by in categories: internet, robotics/AI

ChatGPT creator OpenAI has developed internal tools for watermarking and tracking AI-generated content with 99.9 percent accuracy, the Wall Street Journal reports — but is refusing to release it.

Effective tools for flagging AI-generated text could be useful in any number of situations, from cracking down on cheating students to sorting through the AI-generated sludge filling the web.

Which is why it’s so surprising that OpenAI, as the WSJ reports, has been quietly hanging onto tools that could do exactly that.
