A team of researchers has successfully simulated and” observed” a slow-motion chemical reaction at a billion times slower than “normal.”

For the first time ever, scientists have succeeded in slowing down (in simulation) a chemical reaction by around 100 billion times. Using a quantum computer, the researchers simulated and then “observed” the reaction in super slow motion.

Researchers at Duke University have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecules can take to change between different configurations.

The observation method makes use of a quantum simulator, developed from research in quantum computing, and addresses a long-standing, fundamental question in chemistry critical to processes such as photosynthesis, vision and photocatalysis. It is also an example of how advances in quantum computing are being used to investigate fundamental science.

The results appear online August 28 in the journal Nature Chemistry.

Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.

Joint lead researcher and Ph.D. student, Vanessa Olaya Agudelo, said, It is by understanding these basic processes inside and between molecules that we can open up a new world of possibilities in materials science, drug design, or solar energy harvesting.

In this episode, filmed during Abundance360, Peter and David discuss David’s groundbreaking research on reversing aging through epigenetic changes, emphasizing that aging is not just damage to the body but a loss of information. They talk about age reversal as a possibility, rejuvenating brains, and regaining lost memories.

These products may not be as helpful as we thought they were.

The association between this mass concentration and the idea that atoms are empty stems from a flawed view that mass is the property of matter that fills a space. However, this concept does not hold up to close inspection, not even in our human-scale world. When we pile objects on top of each other, what keeps them separated is not their masses but the electric repulsion between the outmost electrons at their touching molecules. (The electrons cannot collapse under pressure due to the Heisenberg uncertainty and Pauli exclusion principles.) Therefore, the electron’s electric charge ultimately fills the space.

Anyone taking Chemistry 101 is likely to be faced with diagrams of electrons orbiting in shells.

In atoms and molecules, electrons are everywhere! Look how the yellow cloud permeates the entire molecular volume in Figure 1. Thus, when we see that atoms and molecules are packed with electrons, the only reasonable conclusion is that they are filled with matter, not the opposite.

The “chemical cocktail” helped reverse aging in mice, but some experts are skeptical about whether it will work in humans.

A potential new way to protect sensitive electronics from the extreme heat generated by flying at high speed could give the United States an edge in the race to deploy hypersonic missiles and new spacecraft.

A July research paper in the American Chemical Society’s journal ACS Nano describes one potential solution that uses focused plasma, the photons and highly charged particles that make up the so-called fourth state of matter. If the method bears out in further research, it could usher in hypersonic weapons with much more advanced electronic guidance and could even enable on-the-ground weapons to evade heat sensors.

The breakthrough grew out of efforts to use a laser to measure the temperature of electronics in plasma-facing environments, work the Air Force is supporting through a grant at the University of Virginia, said professor Patrick Hopkins, one of the researchers on the paper.

This story is part of a series on the current progression in Regenerative Medicine. In 1999, I defined regenerative medicine as the collection of interventions that restore to normal function tissues and organs that have been damaged by disease, injured by trauma, or worn by time. I include a full spectrum of chemical, gene, and protein-based medicines, cell-based therapies, and biomechanical interventions that achieve that goal.

As part of a trio of stories on advances in stem cell gene therapy, this piece discusses how to alter blood stem cells using mRNA technology. Previous installments describe how the same platform could reinvent how we prepare patients for bone marrow transplants and correct pathogenic DNA.

At present, the only way to cure genetic blood disorders such as sickle cell anemia and thalassemia is to reset the immune system with a stem cell transplantation. Only a fraction of patients elects this procedure, as the process is fraught with significant risks, including toxicity and transplant rejection. A preclinical study published in Science explores a solution that may be less toxic yet equally effective: mRNA technology. The cell culture and mouse model experiments offer a compelling avenue for future research to enhance or replace current stem cell transplantations altogether.
