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.

SpaceX still plans for Sunday launch of 23 Starlink smallsats; and now available in Tonga

Posted by in categories: internet, satellites

SpaceX is targeting Sunday, August 4 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 12:24 a.m. PT, with backup opportunities available until 3:52 a.m. PT. If needed, additional opportunities are also available on Monday, August 5 starting at 12:24 a.m. ET.

A Mormon Transhumanist has trained a chatbot that was trained on his entire collection of writings, internet social media posts, and presentations.

I’ve merged with artificial intelligence. Well, I’m working on it. And I’m excited to share the results with you.

! Trained on everything that I’ve written publicly since 2000, he might be better at Mormon Transhumanism than I am.

Quantum Computers Need a Quantum Internet: Here’s Why

Posted by in categories: computing, internet, particle physics, quantum physics

Research on quantum internet technology highlights the challenge of producing stable photons at telecom wavelengths, with recent studies focusing on material improvements and advanced emission techniques to enhance quantum network efficiency.

Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?

The secret to our modern internet is the ability for data to remain intact while traveling over long distances, and the best way to achieve that is by using photons. Photons are single units (“quanta”) of light. Unlike other quantum particles, photons interact very weakly with their environment. That stability also makes them extremely appealing for carrying quantum information over long distances, a process that requires maintaining a delicate state of entanglement for an extended period of time. Such photons can be generated in a variety of ways. One possible method involves using atomic-scale imperfections (quantum defects) in crystals to generate single photons in a well-defined quantum state.
