Crucially, plasma treatment of the old rats reduced the epigenetic ages of blood, liver and heart by a very large and significant margin, to levels that are comparable with the young rats. According to the six epigenetic clocks, the plasma fraction treatment rejuvenated liver by 73.4%, blood by 52%, heart by 52%, and hypothalamus by 11%. The rejuvenation effects are even more pronounced if we use the final versions of our epigenetic clocks: liver 75%, blood 66%, heart 57%, hypothalamus 19%. According to the final version of the epigenetic clocks, the average rejuvenation across four tissues was 54.2%.


Researchers have demonstrated that epigenetic age can be halved in rats by using signals commonly found in the blood.

Epigenetic changes

One of the proposed reasons we age are the changes to gene expression that our cells experience as we get older; these are commonly called epigenetic alterations. These alterations harm the fundamental functions of our cells and can increase the risk of cancer and other age-related diseases.

Linking multiple copies of these devices may lay the foundation for quantum computing.

Once unimaginable, transistors consisting only of several- atom clusters or even single atoms promise to become the building blocks of a new generation of computers with unparalleled memory and processing power. But to realize the full potential of these tiny transistors — miniature electrical on-off switches — researchers must find a way to make many copies of these notoriously difficult-to-fabricate components.

Now, researchers at the National Institute of Standards and Technology (NIST) and their colleagues at the University of Maryland have developed a step-by-step recipe to produce the atomic-scale devices. Using these instructions, the NIST-led team has become only the second in the world to construct a single-atom transistor and the first to fabricate a series of single electron transistors with atom-scale control over the devices’ geometry.

Quantum radar can find them.


The United States military takes extreme caution and protocol when transporting nuclear weapons, but that doesn’t mean accidents haven’t happened in the past. And a nuclear accident sounds like the worst accident of all time. Watch today’s new video where we dive into the mistakes of the military and uncover a story about a live nuke, still lost in an American swamp!

Sometime in the next few hours, the body of a spent Chinese rocket will become the largest piece of space junk in decades to fall, uncontrolled, back towards Earth.

On May 5, a Long March 5B rocket launched a prototype crew capsule resembling a SpaceX Crew Dragon to orbit for a test. Now, after almost a week orbiting the Earth, the core stage of the large rocket is on a collision course with the upper atmosphere and whatever doesn’t burn up during its descent will impact the planet.

“It is the most massive object to make an uncontrolled reentry since the 39-tonne Salyut-7 in 1991,” wrote Jonathan McDowell, a prominent Harvard astrophysicist who tracks objects in orbit, on Twitter.
