Small Tissue Chips in Space a Big Leap Forward for Research
Tissue chips, thumb-drive sized devices that contain human cells in a 3D matrix, represent a giant leap in science.
They can test cells’ response to:
•stresses
•drugs
•genetic changes
The Tissue Chips in Space initiative seeks to better understand the role of microgravity on human health and disease and to translate that understanding to improved human health on Earth.
This series of investigations to test tissue chips in microgravity aboard the International Space Station is planned through a collaboration between the National Center for Advancing Translational Sciences (NCATS) at the National Institutes for Health (NIH) and the National Laboratory in partnership with NASA.
Many of the changes in the human body caused by microgravity resemble the onset and progression of diseases associated with aging on Earth, but in space, changes occur much faster. Scientists may be able to use tissue chips in space to model changes that take months or years to happen on Earth.
A tissue chip needs three properties, according to Lucie Low, scientific program manager at NCATS. “It has to be 3D,” she explained. “It must have multiple different types of cells, and it must have microfluidic channels. Essentially, you get a functional unit of what human tissues are like, outside of the body,” said Low.
As accurate models of the structure and function of human organs, tissue chips provide a model for predicting whether a drug, vaccine or biologic agent is safe in humans more quickly and effectively than current methods.
This first phase of Tissue Chips in Space includes five investigations. An investigation of immune system aging is planned for launch on the SpaceX CRS-16 flight, scheduled for mid-November. The other four, scheduled to launch on subsequent flights, include lung host defense, the blood-brain barrier, musculoskeletal disease and kidney function. This phase tests the effects of microgravity on the tissue chips and demonstrates the capability of the automated system.
All five investigations make a second flight about 18 months later to confirm use of the model, such as testing potential drugs on the particular organs. Four more projects are scheduled for launch in summer 2020, including two on engineered heart tissue to understand cardiovascular health, one on muscle wasting and another on gut inflammation.
Ultimately, the technology could allow astronauts going into space to take along personalized chips that could be used to monitor changes in their bodies and to test possible countermeasures and therapies. That would be a major leap forward in keeping astronauts healthy on missions to deep space!

Your future self is talking shit about you
As a student , there is nothing better than finally finishing a project , then being able to close all the tabs in the browser related to that project

No matter how good a person you are, you are evil in someone’s story.
No matter how many times I see this plane. It still blows my mind how this beautiful engineering marvel became a reality.

Can confirm that seeing this for real is magnificent. At night would have been ever better.
Ad Astra, John Glenn (1921-2016)
An astronaut.
A pilot.
A husband.
A father.
A United States Senator.
An American hero.
An original.
John Glenn (1921-2016) was all those things and more. When he rocketed into space on Feb. 20, 1962, to become the first American to orbit Earth, the flight set the nation on course to meet ever-more ambitious goals.
The life and career of Senator Glenn eclipses those of many. In spite of his accomplishments, he was a humble and gracious man (and 4-term U.S. senator).
During Glenn’s first flight, a scheduled 30-minute test to determine whether Glenn could fly the capsule manually became a matter of life and death when the automatic system malfunctioned after the first orbit.
“I went to manual control and continued in that mode during the second and third orbits, and during re-entry,” Glenn recalled later. “The malfunction just forced me to prove very rapidly what had been planned over a longer period of time.” Another problem seemed even more serious – telemetry indicated the spacecraft’s heat shield was loose. It seemed possible that Glenn and the spacecraft would be incinerated on re-entry. Glenn left the retrorocket pack in place to steady the heat shield during re-entry. “It made for a very spectacular re-entry from where I was sitting,” he said. Big chunks of the burning material came flying by the window.
He wasn’t sure whether the flaming debris was the rocket pack or the heat shield breaking up. “Fortunately,” he told an interviewer,“ it was the rocket pack – or I wouldn’t be answering these questions.”
In the words of President Obama, who awarded him the Presidential Medal of Freedom in 2012: “When John Glenn blasted off from Cape Canaveral atop an Atlas rocket in 1962, he lifted the hopes of a nation. And when his Friendship 7 spacecraft splashed down a few hours later, the first American to orbit the Earth reminded us that with courage and a spirit of discovery there’s no limit to the heights we can reach together. With John’s passing, our nation has lost an icon and Michelle and I have lost a friend. John spent his life breaking barriers, from defending our freedom as a decorated Marine Corps fighter pilot in World War II and Korea, to setting a transcontinental speed record … The last of America’s first astronauts has left us, but propelled by their example we know that our future here on Earth compels us to keep reaching for the heavens. On behalf of a grateful nation, Godspeed, John Glenn.”
Glenn left the Astronaut Corps in 1964 and resigned from the Marine Corps in 1965. And, after some time in private industry ran for and was elected ti the U.S. Senate in 1974, carrying all 88 counties of Ohio. He was re-elected in 1980 with the largest margin in Ohio history. Ohio returned him to the Senate for a third term in 1986. In 1992 he was elected again, becoming the first popularly elected senator from his state to win four consecutive terms. During his last term he was the ranking member of both the Governmental Affairs Committee and the Subcommittee on Air/Land Forces in the Senate Armed Services Committee. He also served on the Select Committee on Intelligence and the Special Committee on Aging. He was considered one of the Senate’s leading experts on technical and scientific matters, and won wide respect for his work to prevent the spread of weapons of mass destruction.
In 1998, Glenn flew on the STS-95 Discovery shuttle flight, a 9-day mission during which the crew supported a variety of research payloads including deployment of the Spartan solar-observing spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, and Glenn’s investigations on space flight and the aging process.
NASA Administrator Charlie Bolden remembers, “Senator Glenn’s legacy is one of risk and accomplishment, of history created and duty to country carried out under great pressure with the whole world watching.”
Today, we honor him for all that he stood for and continues to stand for – grace under pressure, humility, ability, strength.
Godspeed, John Glenn.
I am grateful to have lived while he was still. I know that isn’t much, but truly it’s an honor to be alive while a hero was still among us.
Let’s just casually spread it until it becomes an actual thing.
Ford Unitron, 1961. Designed in the fall of 1960 in the Corporate Advanced Studio by Dean Beck, a recent graduate of the Art Center. The Unitron began as a suggestion from a Ford Division manager who believed Ford should be involved in the coming recreation vehicle market. Elwood Engel gave the assignment to Beck who was supervised by studio manager, Gale Halderman. Dean Beck’s Unitron artwork, of which over a dozen exist, shows variations including a camper van, paneled delivery van, a pick-up as well as a passenger van.
