New theory suggests aging is driven by degenerative metabolic reprogramming over time

THIS IS HUGE!! New study suggests that aging could be preventable, delayable and even reversible! A recent study published in Engineering proposes a new theory called pro aging metabolic reprogramming (PAMRP)

Aging is a complex process that has long puzzled scientists. A recent study published in Engineering proposes a new theory called pro-aging metabolic reprogramming (PAMRP), which could change our understanding of aging.

The traditional debate on aging has centered around whether it is a programmed process or a result of stochastic events. The PAMRP theory combines these two perspectives. It suggests that aging is driven by degenerative metabolic reprogramming over time. This involves both the buildup of pro-aging substrates (PASs) through and the emergence of pro-aging triggers (PATs). The combination of PASs and PATs leads to metabolic reprogramming, which in turn causes cellular and genetic reprogramming, ultimately resulting in the aging process.

Metabolism plays a crucial role in the PAMRP theory. As organisms age, there are significant changes in metabolic pathways, such as shifts in energy production and nutrient utilization. These changes initially serve as an adaptive mechanism but can become maladaptive over time, contributing to aging. The theory also distinguishes between different types of metabolic reprogramming, such as adaptive and adverse, and between regenerative and degenerative processes.

Scientists Solve a 40-Year Quantum Mystery That Could Change Electronics Forever

Quantum chaos, previously theoretical, has been observed experimentally, validating a 40-year-old theory about electrons forming patterns in confined spaces.

Using advanced imaging techniques on graphene, researchers confirmed “quantum scars,” where electrons follow unique closed orbits. These findings could revolutionize electronics by enabling efficient, low-power transistors and paving the way for novel quantum control methods. This discovery offers insights into chaotic quantum systems, bridging a gap between classical and quantum physics.

Patterns in chaos revealed in quantum space.

DeepMind’s Genie 2 can generate interactive worlds that look like video games

DeepMind, Google’s AI research org, has unveiled a model that can generate an “endless” variety of playable 3D worlds.

Called Genie 2, the model — the successor to DeepMind’s Genie, which was released earlier this year — can generate an interactive, real-time scene from a single image and text description (e.g. “A cute humanoid robot in the woods”). In this way, it’s similar to models under development by Fei-Fei Li’s company, World Labs, and Israeli startup Decart.

DeepMind claims that Genie 2 can generate a “vast diversity of rich 3D worlds,” including worlds in which users can take actions like jumping and swimming by using a mouse or keyboard. Trained on videos, the model’s able to simulate object interactions, animations, lighting, physics, reflections, and the behavior of “NPCs.”

Newly Discovered Brain Circuit Predicts Response to Stress

Summary: Researchers identified a brain circuit involving the amygdala and hippocampus that predicts resilience to stress in mice. Mice with disrupted neural communication in this circuit struggled to seek rewards, but activating the neurons restored resilience and improved decision-making.

Using chemogenetics, the team stimulated brain activity in less resilient mice, which then displayed normal behavior and sought sweetened water. This breakthrough suggests potential new, non-invasive treatments for chronic stress and depression in humans, with researchers now exploring similar patterns in human brains.
