Plasma is the 4th state of matter and it comes in many flavors. You probably know it from it’s greatest hits, fire and lightning, but there is a lot more to plasma than most people are aware of. Cold plasma is my personal favorite as it has the same beautiful glow that all plasma have, but it’s no warmer than room temp and feels cold to the touch. In this video we go through my year long journey to harness this weird state of matter into a torch that can be used for future experiments and in the lab.

NASA has completed the structural test campaign for NASA’s Space Launch System rocket at NASA’s Marshall Space Flight Center in Huntsville, Alabama. A test version of the rocket’s liquid oxygen tank was purposely pushed to its limits on June 22.

The final test concludes a nearly three-year structural test series that qualified the structural design of multiple hardware elements for the rocket that will launch NASA’s Artemis missions and astronauts to the Moon. WATCH go.nasa.gov/9312

“Watching Apollo footage of astronauts doing geology on the surface of the Moon is a really great way to think about preparing for Artemis.” —Goddard scientist Kelsey Young.

Here’s how #NASA is preparing astronauts to do science on the Moon.

Before NASA astronauts fly the Orion spacecraft on Artemis missions to the Moon and back, engineers needed to thoroughly test its ability to withstand the stresses of launch, climb to orbit, the harsh conditions of deep space transit, and return to Earth. NASA designed Orion from the beginning specifically to support astronauts on missions farther from Earth than any other spacecraft built for humans.

In June 2020, engineers completed testing on a duplicate of Orion called the Structural Test Article (STA), needed to verify the spacecraft is ready for Artemis I — its first uncrewed test flight. NASA and its prime contractor, Lockheed Martin, built the STA to be structurally identical to Orion’s main spacecraft elements: the crew module, service module and launch abort system.

The STA testing required to qualify Orion’s design began in early 2017 and involved 20 tests, using six different configurations — from a single element, to the entire full stack — and various combinations in between. At completion, the testing verified Orion’s structural durability for all flight phases of Artemis I.

Why do we age? What exactly is happening in our bodies? And can we do anything about it? Mankind has sought answers to these questions since time immemorial. While the pharmaceutical scientists Alexandra K. Kiemer and Jessica Hoppstädter from Saarland University are not claiming to have solved this ancient problem, they have uncovered processes within our immune system that contribute to aging. Kiemer and Hoppstädter have shown that low levels of the hormone cortisol and the protein known as GILZ can trigger chronic inflammatory responses in the body. The results have been published in the journal Aging Cell.

The phenomenon of human aging is the result of a complex interaction between numerous factors, with our own immune system playing a critical role. As we get older, our body’s own defense mechanisms age, too. The adaptive or specific immune system that each of us acquires over the course of our lives and that protects us from the pathogens that we came into contact with gradually deteriorates as we age. In contrast, however, our innate or non-specific immune system, which is the first line of defense towards a wide variety of pathogens, becomes overactive. The result is chronic inflammation.

A persistent state of inflammation can cause serious damage to our bodies. One consequence is that chronic inflammatory diseases, such as atherosclerosis or arthritis, are far more prevalent in older patients. “This has been well-known for a long time. In fact, the scientific community refers to this phenomenon as ‘inflamm-aging’—a portmanteau word that combines the two inseparably linked processes of inflammation and aging,” explains Alexandra K. Kiemer, Professor of Pharmaceutical Biology at Saarland University.

The circumstances of this case are so highly unique, the prospect of replicating it are quite uncertain.

China is even developing a satellite-based laser surveillance system aimed at detecting vessels submerged as deep as five hundred meters.

Here’s What You Need To Remember: Time will tell which, if any, of these technologies can be developed into practical operational systems.

Discovery likely to be first of a previously unknown class of particles, researchers say.
