Rapamycin and Longevity: A Few Thoughts On Dosing

Posted by in categories: biotech/medical, life extension

What’s the optimal way to dose a longevity drug like rapamycin? Nils Osmar looks at some different studies that provide a possible answer:


It’s worth noting that mTORC2 is not directly inhibited by rapamycin under most circumstances, but can be under some. Some studies have found that after prolonged use, rapamycin can also begin inhibiting mTORC2 (see study: Alternative rapamycin treatment regimens mitigate the impact of rapamycin on glucose homeostasis and the immune system).

So taking breaks from rapamycin may also be beneficial.

3D-printed “metamaterial” is stronger than anything in nature

Posted by in categories: biotech/medical, materials

Using lasers and metal powder, Australian scientists have created a super strong, super lightweight new — but they got the idea for this sci fi-sounding creation from plants.

The challenge: Materials that are strong yet lightweight, such as carbon fiber and graphene, are used to make everything from medical implants to airships, and developing ones with ever greater “strength-to-weight ratios” is the goal of many material scientists.

In pursuit of that goal, some have turned to nature, looking for ways to replicate in metal the hollow lattice structures, like those in the Victoria water lily, that make some plants remarkably strong.

Charge travels like light in bilayer graphene

Posted by in categories: computing, nanotechnology, particle physics

An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels.

Furthermore, they have shown that the current can be “switched” on and off, which has potential for developing tiny, energy-efficient transistors – like the light switch in your house but at a nanoscale.

The Massachusetts Institute of Technology (MIT), USA, and the National Institute for Materials Science (NIMS), Japan, were also involved in the research. The results were published in Nature Communications (“Probing the tunable multi-cone band structure in Bernal bilayer graphene”).

AI could gobble up a quarter of all electricity in the U.S. by 2030 if it doesn’t break its energy addiction, says Arm Holdings exec

Posted by in categories: mobile phones, robotics/AI

Right now generative AI has an “insatiable demand” for electricity to power the tens of thousands of compute clusters needed to operate large language models like OpenAI’s GPT-4, warned chief marketing officer Ami Badani of chip design firm Arm Holdings.

If generative AI is ever going to be able to run on every mobile device from a laptop and tablet to a smartphone, it will have to be able to scale without overwhelming the electricity grid at the same time.

“We won’t be able to continue the advancements of AI without addressing power,” Badani told the Fortune Brainstorm AI conference in London on Monday. “ChatGPT requires 15 times more energy than a traditional web search.”
