Harvard Scientists Have Developed a Groundbreaking Solution to Hearing Loss

Posted by in categories: media & arts, neuroscience

A group of scientists at Harvard Medical School are the pion-ears of innovative developments in hearing loss treatment.

Researchers at the school’s Mass Eye and Ear hospital claim to have developed a groundbreaking solution to hearing loss, one of the music community’s most vexing and elusive problems.

According to a study published in the Proceedings of the National Academy of Sciences, the researchers formulated a “drug-like cocktail” comprising various molecules that regenerate the inner ear hair cells responsible for relaying sounds to the brain.

In January, new reports on Apple’s long-awaited augmented reality/virtual reality headset were released. And if what’s in these reports is even partially true, Apple is poised to give the world one of the most jaw-dropping, powerful pieces of technology in history (again) — which is why it was a bit surprising that this news didn’t make more of a splash.

This is the same company that has fans enter lotteries for tickets to corporate keynote addresses! Yet, outside of the usual tech blogs and a few newspaper columns, the future of Apple’s AR/VR device went largely unnoticed.

Deep learning pioneer Geoffrey Hinton quits Google

Posted by in categories: bioengineering, robotics/AI

Geoffrey Hinton, a VP and engineering fellow at Google and a pioneer of deep learning who developed some of the most important techniques at the heart of modern AI, is leaving the company after 10 years, the New York Times reported today.

According to the Times, Hinton says he has new fears about the technology he helped usher in and wants to speak openly about them, and that a part of him now regrets his life’s work.

Mark Zuckerberg says AI boosts monetization

Posted by in categories: business, robotics/AI, supercomputing

AI is having its moment on tech earnings calls for the second consecutive quarter, following the widely popular launch of OpenAI’s ChatGPT in late November. But not every company has the same plans for the new technology.

Nvidia (NVDA) is selling AI powered supercomputers. Microsoft (MSFT) is integrating ChatGPT into its search engine to compete with Google (GOOGL), which has its own AI searchbot.

Meta’s approach is slightly different. The core business for Meta since the early days of Facebook has been advertising sales, which still account for 98% of the company’s quarterly revenue. So naturally, enhancing advertisements with AI is where Meta believes the new technology can be most impactful.

Can AI Develop Empathy & Ethics?

Posted by in categories: ethics, robotics/AI

Can we ensure that AI is used ethically? Will AIs themselves develop empathy and ethics? That’s the topic I’d like to discuss today. It’s important.

I recently sat down with Rana el Kaliouby, PhD, AI researcher and Deputy CEO of Smart Eye, at my private CEO Summit Abundance360 to explore these questions. Rana has been focused on this very topic for the past decade.

A megaprotein brake for aging and insulin-mTOR signaling

Posted by in category: life extension

Insulin-mTOR signaling drives anabolic growth in organismal development, while its late-life antagonistic pleiotropy affects aging and compromises lifespan across animal phylogeny. Here we identify LPD-3 as a megaprotein that orchestrates the tempo of insulin-mTOR signaling during C. elegans aging. We find that an agonist insulin INS-7 is drastically over-produced and shortens lifespan in lpd-3 mutants, a C. elegans model of human Alkuraya-Kučinskas syndrome. LPD-3 forms a bridge-like tunnel megaprotein to facilitate phospholipid trafficking to plasma membrane. Lipidomic profiling reveals increased abundance of hexaceramide species in lpd-3 mutants, accompanied by up-regulation of hexaceramide biosynthetic enzymes, including HYL-1 (Homolog of Yeast Longevity). Reducing HYL-1 activity decreases INS-7 levels and rescues the shortened lifespan of lpd-3 mutants through insulin receptor/DAF-2 and mTOR/LET-363. LPD-3 antagonizes SINH-1, a key mTORC2 component, and reduces protein abundance with age in wild type animals. We propose that LPD-3 acts as a megaprotein brake for aging and its age-dependent decline restricts lifespan through the sphingolipid-hexaceramide and insulin-mTOR pathways.

The authors have declared no competing interest.
