Mark Zuckerberg is set to enter the AI space and join the AI hype by launching chatbots on Facebook’s social media platforms.

With tech giant companies joining the artificial intelligence race to keep up with the new technology demand, Meta’s owner is all set to launch a variety of AI-backed chatbots.

Financial Times (FT) reported earlier today (2 Aug 2023) that the chatbots will launch as soon as next month. With the ambition to boost engagement, the tech giant has been designing new persona-based chatbot prototypes that can have humanlike discussions with its nearly four billion users.

“The ad money will otherwise be kept by X if you are not an X Premium (Blue) subscriber,” Musk said in a post.

To be eligible for the program, creators also need to be at least 18 years old, have a minimum of 500 followers, and have 15 million or more “organic impressions” on posts within the last three months.

The price of an X premium subscription starts at $8 per month, or $84 a year, and it gives users access to extra features such as “Edit.”

Researchers from MIT have demonstrated a photonics-based computing system that could lead to machine-learning programs several orders of magnitude more powerful than the one behind ChatGPT. The researchers reported a greater than 100-fold improvement in energy efficiency and a 25-fold improvement in compute density — a measure of system power — over state-of-the-art digital computers for machine learning.

In the near term, the researchers’ experimental, laser-based system could be further developed to improve these metrics by two more orders of magnitude, the researchers said.

Will the cities of the future be climate neutral? Might they also be able to actively filter carbon dioxide out of the air? Futurologist Vincente Guallarte thinks so. In fact, he says, our cities will soon be able to absorb CO₂, just like trees do.

In a breakthrough for optical computing, researchers developed a nanosecond-scale volatile modulation scheme integrating a phase-change material.

Technological advancements such as autonomous driving and computer vision have spurred a significant increase in demand for computational power. Optical computing, characterized by its high throughput, energy efficiency, and low latency, has attracted significant interest from both academia and industry. However, current optical computing chips are hampered by their power consumption and size, which limit the scalability of optical computing networks.

Nonvolatile integrated photonics has emerged to address these issues, offering optical computing devices the ability to perform in-memory computing while operating with zero static power consumption. Phase-change materials (PCMs), with their high refractive index contrast between different states and reversible transitions, have become promising candidates for enabling photonic memory and nonvolatile neuromorphic photonic chips. This makes PCMs ideally suited for large-scale nonvolatile optical computing chips.

Rotifers are excellent research organisms for studying the biology of aging, DNA repair mechanisms, and other fundamental questions. Now, using an innovative application of CRISPrCas9, scientists at the Marine Biological Laboratory, Woods Hole, have devised a method for making precise, heritable changes to the rotifer genome, enabling the larger community of scientists to deploy the rotifer as a genetically tractable lab organism.

Scientists with the Huazhong University of Science and Technology have replicated LK-99’s levitation abilities at room temperature, which they showcased in a video uploaded to Billibilli.

Topology has become a critical factor in the field of modern condensed matter physics and beyond. It explains the way solid materials may possess two distinct and seemingly conflicting characteristics. An example of this is topological insulators, materials whose bulk acts as an insulator, and can still conduct electricity at their surfaces and edges.

Over the past several decades, the idea of topology has revolutionized the understanding of electronic structure and the overall properties of materials. Additionally, it has opened doors to technological advancements by facilitating the integration of topological materials into electronic applications.

At the same time, topology is quite tricky to measure, often requiring combinations of multiple experimental techniques such as photoemission and transport measurements. A method known as high harmonic spectroscopy has recently emerged as a key technique to observe the topology of a material. In this approach a material is irradiated by intense laser light.
