Eggs from older mice regain youth when grown in young cells

Posted by in category: life extension

Growing immature eggs from old mice in the ovarian structures of young mice can reverse signs of ageing in the eggs1.

“Think of this as a five-star anti-ageing spa for the old egg,” says Rong Li, a cell biologist at the National University of Singapore (NUS), who co-authored a study describing the results.

When the rejuvenated eggs were fertilized, the resulting embryos were almost four times more likely to give rise to healthy pups than the eggs that matured in the old environment. The results are published in Nature Aging today.

Novel coupled nanopore platform offers greater precision for detecting molecules

Posted by in categories: biotech/medical, nanotechnology

“As complex living systems, we likely have trillions upon trillions of tiny nanoscopic holes in our cells that facilitate and regulate the crucial processes that keep us alive and make up who are,” says Marija Drndić, a physicist at the University of Pennsylvania who develops synthetic versions of the biological pores that “guide the exchange of ions and molecules throughout the body.”

The ability to control and monitor the flow of molecules through these pores has opened new avenues for research in the last two decades, according to Drndić, and the field of synthetic nanopores, where materials like graphene and silicon are drilled with tiny holes, has already led to significant advances in DNA sequencing.

In a paper published in Nature Nanotechnology (“Coupled nanopores for single-molecule detection”), Drndić and Dimitri Monos, her longtime collaborator at the Perelman School of Medicine and Children’s Hospital of Philadelphia (CHOP), presented a new kind of nanopore technology with the development of a dual-layer nanopore system: a design that consists of two or more nanopores, stacked just nanometers apart, which allows for more precise detection and control of molecules like DNA as they pass through.

The FBI spent decades tracking mathematician Paul Erdős, only to conclude that the guy was just really into math

Posted by in category: mathematics

Someone went through Paul Erdos’ FBI files and found that all suspicious activities was really just him doing math.


A Hungarian born in the early 20th century, Paul (Pal) Erdős, mathematician, was well-known and well-liked, the sort of eccentric scientist from the Soviet sphere that made Feds’ ears perk up in mid-century America. His lifetime generated over 500 scholarly papers and a cult of collaborators. The Erdős number has become a mathy merit badge, and for those that don’t hold a coveted Erdős number of 1, there are resources to determine just how many degrees of celebrity separation exist between the man himself and other technical paper bylines.

But, try as they might, the Federal Bureau of Investigation was never able to find much motivation behind his movements and acquaintances beyond the math of it all.

Quantum researchers cause controlled ‘wobble’ in the nucleus of a single atom

Posted by in categories: particle physics, quantum physics

Researchers from Delft University of Technology in The Netherlands have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom. This electron could be manipulated and read out through the needle of a scanning tunneling microscope.

Declassified Nuclear Tests — Enhanced with AI — Slow Motion

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

The following declassified nuclear test footage has been enhanced using AI with techniques such as slow motion, frame interpolation, upscaling, and colorization. This helps improve the clarity and visual quality of the original recordings, which were often degraded or limited by the technology of the time. Experiencing these shots with enhanced detail brings the devastating power of atomic weapons into focus and offers a clearer perspective on their catastrophic potential and impact.

OpenAI Launching “Strawberry” Model With “Human-Like Reasoning” as Soon as This Week

Posted by in categories: innovation, robotics/AI

ChatGPT maker OpenAI is rumored to be imminently releasing a brand-new AI model, internally dubbed “Strawberry,” that has a “human-like” ability to reason.

As Bloomberg reports, a person familiar with the project says it could be released as soon as this week.

We’ve seen rumors surrounding an OpenAI model capable of reasoning swirl for many months now. In November, Reuters and The Information reported that the company was working on a shadowy project called Q — pronounced Q-Star — which was alleged to represent a breakthrough in OpenAI’s efforts to realize artificial general intelligence, the theoretical point at which an AI could outperform a human.

The Physics and Philosophy of Time Travel

What if everything we know about time is merely an illusion? Could find a way out of it, by breaking the construct of how the universe progresses? And so, would it be possible to break the natural flow of time?
