The Grok AI chatbot that X has been testing is becoming more widely available.

Lamini AI CEO and cofounder Sharon Zhou shows it’s possible to build an AI startup without Nvidia’s GPUs by using chips from AMD instead.

A recently tenured faculty member in MIT’s departments of Mechanical Engineering and Materials Science and Engineering, Kim has made numerous discoveries about the nanostructure of materials and is funneling them directly into the advancement of next-generation electronics.

His research aims to push electronics past the inherent limits of silicon — a material that has reliably powered transistors and most other electronic elements but is reaching a performance limit as more computing power is packed into ever smaller devices.

Today, Kim and his students at MIT are exploring materials, devices, and systems that could take over where silicon leaves off. Kim is applying his insights to design next-generation devices, including low-power, high-performance transistors and memory devices, artificial intelligence chips, ultra-high-definition micro-LED displays, and flexible electronic “skin.” Ultimately, he envisions such beyond-silicon devices could be built into supercomputers small enough to fit in your pocket.

Salk scientists unveil RNA capabilities that enable Darwinian evolution at a molecular scale, and bring researchers closer to producing autonomous RNA life in the laboratory.

Charles Darwin described evolution as “descent with modification.” Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must also be somewhat flexible, allowing slight variations of genes to arise over time and introduce new traits into the population.

Researchers create a compact, all-optical device with the lowest microwave noise ever achieved for an integrated chip.

In a new Nature study, Columbia Engineering researchers have built a photonic chip that can produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device — a chip so small, it could fit on a sharp pencil point — results in the lowest microwave noise ever observed in an integrated photonics platform. The achievement provides a promising pathway towards small-footprint ultra-low-noise microwave generation for applications such as high-speed communication, atomic clocks, and autonomous vehicles.

A new report warns of potentially major disruption to UK employment from the coming wave of AI. An estimated 11% of tasks are already exposed to current AI, a figure that could rise to 59% during a second wave. But there could also be opportunities for economic growth.

From the discovery and use of fire in the Stone Age, through to the handheld smartphones of today, technology has improved our living standards and is the foundation of modern society. Yet unmanaged technological change comes with risks and disruptions. The current wave of technology including generative AI – described by some as the “Fourth Industrial Revolution” – promises transformative benefits, while at the same time bringing potential disruption through its impact on wage inequality, wealth inequality, and job displacement.

Administrative tasks take up a large share of a doctor’s working hours, reducing the time for patient contact and contributing to a stressful work situation. Researchers at Uppsala University Hospital and Uppsala University, in collaboration with Danderyd Hospital and the University Hospital of Basel, Switzerland, have shown in a new study that the AI model ChatGPT can write administrative medical notes up to ten times faster than doctors without compromising quality.

OpenAI on Friday revealed a voice-cloning tool it plans to keep tightly controlled until safeguards are in place to thwart audio fakes meant to dupe listeners.

A model called “Voice Engine” can essentially duplicate someone’s speech based on a 15-second audio sample, according to an OpenAI blog post sharing results of a small-scale test of the tool.

“We recognize that generating speech that resembles people’s voices has serious risks, which are especially top of mind in an election year,” the San Francisco-based company said.

This H+ Roundtable features Anders Sandberg and Francesca Minerva in a discussion on Brain Enhancements and Rights. The event took place on March 14, 2021.

The H+ Academy is an opportunity to face the world’s issues with leading thinkers of AI, Philosophy, Economics, Science and the Arts.
