Jellyfish shown to learn from past experience for the first time

Posted by in category: neuroscience

Jellyfish are more advanced than once thought. A new study from the University of Copenhagen has demonstrated that Caribbean box jellyfish can learn at a much more complex level than ever imagined—despite only having one thousand nerve cells and no centralized brain. The finding changes our fundamental understanding of the brain and could enlighten us about our own mysterious brains.

After more than 500 million years on Earth, the immense evolutionary success of is undeniable. Still, we’ve always thought of them as simple creatures with very limited learning abilities.

The prevailing opinion is that more advanced nervous systems equate with more advanced learning potential in animals. Jellyfish and their relatives, collectively known as cnidarians, are considered to be the earliest living animals to develop nervous systems and to have fairly simple nervous systems and no centralized brain.

Sci-Fi Short Film “Augmented” | DUST | Flashback Friday

Posted by in categories: augmented reality, entertainment

Fascinating… when can we expect this to be invented?

A short film set in the near future, where augmented reality has become so ubiquitous that the line between the real and virtual worlds have become blurred. When a new, dangerous technology is created that can manipulate the perception of this brave new world, who will exploit it? Who will monetize it? Who will become twisted by it?

Waymo giving Angelenos chance to enjoy autonomous ride service

Posted by in category: robotics/AI

Waymo is offering some Los Angeles residents the chance to ride in the self-driving car across the city.

The company is kicking off its Waymo One tour, which they say is ‘the world’s first fully autonomous ride-hailing service,’ in October.

“Chauffeured by the Waymo Driver — Waymo’s autonomous driving technology that never gets distracted, drowsy or drunk — Angelenos will discover new and stress-free ways to explore their city, whether it’s finding hidden gem thrift spots in Mid City, trying a new cafe in Koreatown or catching a concert in DTLA,” the company said.

Violating the Universal Kasha’s Rule — Scientists Uncover Secrets of a Mysterious Blue Molecule

Posted by in categories: chemistry, energy

Scientists from IOCB Prague are the first to describe the causes of the behavior of one of the fundamental aromatic molecules, azulene. This molecule has captivated the scientific community not just with its distinct blue hue, but also with its unique properties.

Their current undertaking will influence the foundations of organic chemistry in the years to come and in practice will help harness the maximum potential of captured light energy. Their findings were recently published in the Journal of the American Chemical Society (JACS).

Azulene has piqued the curiosity of chemists for many years. The question of why it is blue, despite there being no obvious reason for this, was answered almost fifty years ago by a scientist of global importance, who, coincidentally, had close ties with IOCB Prague, Prof. Josef Michl.

Engineers develop enhanced GaN-based LED array visible light communication system

Posted by in categories: energy, internet, quantum physics

Under the limitation of current density, micro-LED is difficult to achieve watts level optical power, which is not suitable for long-distance and underwater optical communication that requires high-power optical transmitter devices. Therefore, how to improve the communication performance of conventional-size LED is also a key issue at present.

The authors of an article published in Opto-Electronic Science studied a wavelength division multiplexing visible light communication system based on multi-color LED. The system uses a Si substrate GaN-based LED with a 3D structured quantum well. In the active layer of this LED, there is a three-dimensional structure (“V” shaped pit, or V-pit) with a hexagonal profile, opening towards the P-type GaN layer.

With the large-scale commercial use of 5G, global academia and industry have started research on the next-generation mobile communication technology (6G).

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.
