They also developed non-noble metal catalysts, including molybdenum-doped nickel-cobalt phosphide and plasma-induced iron composite cobalt oxide bifunctional electrodes, which showed high durability and activity. These electrodes enabled hydrogen and oxygen production at different times and locations by switching the current direction, resulting in low cell voltages, high decoupling efficiency, and high energy conversion efficiency.

To improve layered double hydroxide (LDH) electrodes, which suffer from limited capacity and poor conductivity/stability, the researchers used non-thermal plasma technology to fabricate nitrogen-doped nickel-cobalt LDH and nitrogen-doped reduced /nickel-cobalt LDH electrodes, which significantly improved capacity and conductivity.

Two-step water electrolysis shows promise for large-scale hydrogen storage and applications such as 5G base stations and data centers. “Our performance indicators for two-step water electrolysis for hydrogen production are synchronized with advanced indicators globally, marking an important step towards industrial operation,” said Prof. Chen Changlun.

An experiment uncovers the role played by gravity in Ostwald ripening, a spontaneous thermodynamic process responsible for many effects such as the recrystallization of ice cream.

What do magnets and decaf coffee have in common? Both involve physical systems that belong to the same “universality class.” Ferromagnetic materials are used to make magnets, and supercritical carbon dioxide extracts caffeine from coffee beans. At the critical point, when ferromagnetic and liquid–gas phase transitions occur, these two systems are described by the same critical exponents [1]. By identifying a system’s universality class, one can quantitatively characterize its behavior at the critical point without prior knowledge of microscopic details. Observing macroscopic properties suffices. However, taking that shortcut is often experimentally challenging, not least because many interesting systems are opaque to light.

We’re expanding access to Meta AI – the assistant in our apps and devices – and introducing new features to help you with answers, ideas and inspiration. Meta AI is now available in 22 countries, with the newest today in Argentina, Chile, Colombia, Ecuador, Mexico, Peru and Cameroon. You can also interact with Meta AI across WhatsApp, Instagram, Messenger and Facebook in new languages: Hindi Hindi-Romanised Script, French, German, Italian, Portuguese and Spanish with more to come.

With Meta AI across WhatsApp, Instagram, Messenger, Facebook and meta.ai, people are tapping into the power of AI to get more done in less time, bring creative ideas to life and expand their knowledge. From tackling how-to tasks and answering questions to providing inspiration and guidance, Meta AI has enhanced people’s daily routines and been a creative partner to lean on. This is just the start — we’re listening to your feedback, updating Meta AI every two weeks to enhance your experience and innovating quickly to bring new features to help you create, get inspired and get more done.

I think there has always been underpinning of this but somehow it seems almost everywhere now even in the media.


It should go without saying that these kinds of beliefs are fantasy, not rooted in any rational fact or evidence. Hence, someone observing from afar the rise in conspiratorial beliefs and pseudoscience might characterize a vast swath of the American public as delusional. From the COVID-truther movement to people believing the 2020 presidential election was rigged, it appears that the body politic is — to put it mildly — no longer on the same page.

Given the perturbed psychological state of so many Americans, it is worth asking if something is happening — psychologically speaking — that is causing many Americans to live in very different realities.

Psychologists say yes; and, moreover, that what is happening was actually predicted long ago by Swiss psychiatrist Carl Jung. Indeed, Jung once wrote that the demise of society wouldn’t be a physical threat, but instead mass delusion — a collective psychosis of sorts.

KAN or MLP: a fairer comparison.

Machine learning (ML) is one of the most important subareas of AI used in building great AI systems.

In ML, deep learning is a narrow area focused solely on neural networks. Through the field of deep learning, systems like ChatGPT and many other AI models can be created. In other words, ChatGPT is just a giant system based on neural networks.

However, there is a big problem with deep learning: computational efficiency. Creating big and effective AI systems with neural networks often requires a lot of energy, which is expensive.

Neural networks biological and artificial.


Neural Networks have found applications across various domains due to their ability to learn from data and improve over time without human intervention. They can solve challenging problems that are hard or impossible to solve using traditional methods. Here are some of the examples of how neural networks and artificial neurons are used in real-world scenarios:

Voice assistants: Voice assistants like Siri and Alexa use neural networks to understand spoken language commands and questions. They use trained models based on artificial neurons processing vast datasets of speech and text data. They can also generate natural-sounding responses and perform various tasks, such as playing music, setting reminders, searching the web, etc.

Self-driving cars: Self-driving cars use neural networks to perceive the environment and make decisions. They use trained models based on artificial neurons processing vast datasets of images, videos, and sensor data. They can also learn from their own experiences and improve their driving skills over time.
