Chinese AI built off open-source code matches American tech in chatbot benchmark tests

Posted by in categories: government, robotics/AI

These advancements in AI technologies are happening in China despite the stringent measures that the U.S. is placing against its technological ambitions. The bans and embargoes on high-end chips Washington has placed on Beijing meant that Chinese companies have difficulty sourcing Nvidia’s latest, most potent AI processors. While China is hard at work trying to catch up on the hardware side of things, many experts believe it’s still at least a decade away from achieving parity with the United States.

It’s evident, though, that Chinese tech firms can catch up on the software side despite the hardware bans. Nevertheless, the White House wants to change that with a bill in the U.S. Congress that would give the American government more control over limiting the export of American AI code. Some parties are trying to limit the development of open-source AI tech to stop Chinese companies from using it, but doing so might do more harm than good for the U.S.

Clément Delangue, the CEO of Hugging Face, a firm that lets its users share its open-source AI projects, said, “Open-source AI is the foundation of AI development,” referring to how the collaboration of researchers and organizations in the U.S. allowed it to become the world leader in AI, “and it looks like China could do the same thing.”

Engineers develop a recipe for zero-emissions fuel: Soda cans, seawater and caffeine

Posted by in categories: energy, sustainability

A sustainable source for clean energy may lie in old soda cans and seawater. MIT engineers have found that when the aluminum in soda cans is exposed in its pure form and mixed with seawater, the solution bubbles up and naturally produces hydrogen—a gas that can be subsequently used to power an engine or fuel cell without generating carbon emissions. What’s more, this simple reaction can be sped up by adding a common stimulant: caffeine.

In a study appearing today in the journal Cell Reports Physical Science, the researchers show they can produce hydrogen gas by dropping pretreated, pebble-sized aluminum pellets into a beaker of filtered seawater. The aluminum is pretreated with a rare-metal alloy that effectively scrubs aluminum into a pure form that can react with seawater to generate hydrogen. The in the seawater can in turn attract and recover the alloy, which can be reused to generate more hydrogen in a sustainable cycle.

Officials break ground on world’s longest underwater rail tunnel connecting 2 major cities: ‘A milestone in … history’

Posted by in category: transportation

Construction has begun on what will be the world’s largest underwater road and rail tunnel connecting Denmark and Germany, as Newsweek reported.

The tunnel, which is a major component of the European Union’s Scandinavian-Mediterranean corridor plan, runs beneath the Fehmarn strait for more than 11 miles and aims to cut travel times between the two countries. A 45-minute ferry ride may soon be reduced to a quick seven-minute train commute.

Artificial Intelligence in Sound Design: A Revolution or a Threat?

Posted by in categories: media & arts, robotics/AI

In this article, Roman Ponomarenko, sound designer and composer with 20+ years of professional experience, explores the transformative potential of AI in sound design and what this means for the future of music.

Artificial intelligence (AI) is already making significant progress in music and sound design. However, will the sophisticated AI of the future eventually replace human professionals in these fields? Navigating such a complex issue proves to be quite challenging, as AI brings forth a mix of exciting opportunities and daunting challenges.
