Cool science stuff

Plus, the airframe is not designed to withstand the thermal and mechanical stresses of supersonic speed. It would break apart.

 

This stuff always amazes me. Especially when you consider not only the distance, but the fact they're dealing with 1970s technology.

NASA fixes Voyager 2 spacecraft via remote repair from 11 billion miles away

 

Released yesterday. A new 360 of Mars:

 

16 light-hours away.

when they send a command, they have to wait 32 hours to find out whether it's received or not.

 

The last original Voyager engineer retired five years ago. Imagine getting handed the responsibility of operating a spaceship that has all the computing power of a Pong video game connected to an eight-track tape player.

So they are essentially 3D printing tissue matrices and then filling them with the appropriate stem cells and voila! New skin, bone graft, what have you.

Machine sucks up tiny tissue spheroids and prints them precisely


"The researchers were able to create a matrix of spheroids with capillary sprouting in the desired directions. Capillaries are necessary for creation of tissues that can grow and continue to live. They are a means of delivering oxygen and nutrients to the cells, without which, cells will die. Without capillaries, only the outermost cells will receive oxygen and nutrients.

Precise placement of spheroids also allows creation of heterocellular tissues like bone. By beginning with human mesenchymal stem cells, the researchers found that the cells differentiated and self assembled bone tissue.

The ability to produce artificial living tissues is valuable in areas outside of regenerative medicine. Frequently, tissue samples are necessary to test drugs or screen other chemical products. Producing specific tissues for each purpose could help in these endeavors.

The researchers suggest that this method can be cost effective because the equipment required costs under $1,000 and is easy to use. They report that the system "can be useful in a wide variety of applications, including but not limited to organ-on-a-chip devices, drug testing devices, microfluidic, in vitro human disease models, organoid engineering, biofabrication and tissue engineering, biocomputing and biophysics."

ROFL

 

Somewhere, Robert Heinlein is smiling.

 

A Northern Virginia Middle Schooler Has Named NASA's New Mars Rover

Kid names next Mars rover... Oh, either he or someone in his family can really fing write.

"Curiosity. InSight. Spirit. Opportunity. We have the spirit and insight to explore the Moon, Mars and beyond. But, if rovers are to be the qualities of us as a race, we missed the most important thing. Perseverance."

"We, not as a nation, but as humans, will not give up," he continued. "The human race will always persevere into the future."

Dang.

 

Happily, it was not put up to an Internet vote, or it would have been Marsy McMarsface.

 

Saw the video released by NASA. Kid is basically a real-life Sheldon Cooper. Kudos for the "NERD" t-shirt.
