Are Dyson Spheres Actually Possible?
Posted by Dan Breeden in categories: computing, life extension, media & arts, physics
Use code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan. The idea of Dyson Spheres was a radical proposal by the physicist Freeman Dyson, an enormous shell of material enveloping a star. Dyson’s idea may be over half a century old, but interest in looking for such objects has only grown in the decades since. But how would such structures work? Are they physically even possible? And what might someone use them for? Today, we dive into the physics of Dyson spheres. Written & presented by Prof. David Kipping. Edited by Jorge Casas.

Nvidia’s New AI Chip is Delayed, Impacting Microsoft, Google, Meta
Posted by Genevieve Klien in category: robotics/AI
Nvidia’s upcoming artificial intelligence chips will be delayed by three months or more due to design flaws, a snafu that could affect customers such as Meta Platforms, Google and Microsoft that have collectively ordered tens of billions of dollars worth of the chips, according to two people who help produce the chip and server hardware for it.
Nvidia this week told Microsoft, one of its biggest customers, and another large cloud provider about a delay involving the most advanced AI chip in its new Blackwell series of chips, according to a Microsoft employee and another person with direct knowledge.

Watch a robot peel a squash with human-like dexterity
Posted by Dan Kummer in category: robotics/AI
Would be more impressive if it was attached to a humanoid robot body.
A robot can hold a squash, pumpkin or melon in one hand, while it is peeled by the other.

Electrically powered artificial muscle fibers: The new power for soft actuation
Posted by Dan Kummer in categories: cyborgs, robotics/AI, wearables
Electrically powered artificial muscle fibers (EAMFs) are emerging as a revolutionary power source for advanced robotics and wearable devices. Renowned for their exceptional mechanical properties, integration flexibility, and functional versatility, EAMFs are at the forefront of cutting-edge innovation.
A recent review article on this topic was published online in the National Science Review (“Emerging Innovations in Electrically Powered Artificial Muscle Fibers”).

The Term “AI” Has Become a Dirty Word in the World of Marketing
Posted by Saúl Morales Rodriguéz in categories: biotech/medical, health, robotics/AI
It seems that Silicon Valley giants, AAA game developers, and other companies desperately clinging to the AI trend and trying to integrate the technology into any product they own will soon have to rethink their marketing strategies, as a new study conducted by researchers from Washington State University indicates that using terms like “AI” or “artificial intelligence” in product descriptions can negatively impact sales.
To explore the impact of including “AI” in goods and service descriptions on consumers’ purchase intentions, the team conducted six experiments and surveyed over a thousand people, discovering that the use of these terms decreases purchase intention and lowers emotional trust, leading to what any company fears the most – diminishing sales numbers.
Furthermore, the researchers found that putting artificial intelligence in the spotlight can be even more detrimental when it comes to high-risk products – those consumers typically think twice about buying, such as expensive gadgets and medical services – compared to low-risk items, primarily because of the greater likelihood of incurring monetary losses or facing health risks.
