Interested in being an astronaut? NASA now hiring.
Have you ever dreamed of becoming an astronaut? Well, this could be your chance.
NASA revealed on Wednesday that it will begin accepting applications for the next class of astronaut candidates starting on Dec. 14.
The agency is seeking pilots, engineers, scientists and medical doctors, among others to continue work on the International Space Station and to conduct deep space exploration.

Could an interactive swarm of flying “3D pixels” (voxels) allow users to explore virtual 3D information by interacting with physical self-levitating building blocks? (credit: Roel Vertegaal)
We’ll find out Monday, Nov. 9, when Canadian Queen’s University’s Human Media Lab professor Roel Vertegaal and his students will unleash their “BitDrones” at the ACM Symposium on User Interface Software and Technology in Charlotte, North Carolina.
Programmable matter
Vertegaal believes his BitDrones invention is the first step towards creating interactive self-levitating programmable matter — materials capable of changing their 3D shape in a programmable fashion, using swarms of tiny quadcopters. Possible applications: real-reality 3D modeling, gaming, molecular modeling, medical imaging, robotics, and online information visualization.
Researchers from Beijing and Philadelphia develop a method to 3D print embryonic stem cells in highly uniform blocks.
Researchers from Tsinghua University in Beijing, China and Drexel University in the US have developed an extrusion-based 3D printing method to produce highly uniform “blocks” of embryonic stem cells. These blocks are a grid-like 3D structure that was able to demonstrate cell viability and rapid self-renewal while maintaining high pluripotency. Lead author Wei Sun says, “It was really exciting to see that we could grow embryoid body in such a controlled manner. The grown embryoid body is uniform and homogenous, and serves as much better starting point for further tissue growth.”
Other common methods of printing stem cells are either done in 2D or with the “suspension” method, but these methods do not produce cells with the same cell uniformity and homogenous proliferation as that of the 3D method. This new method would enable researchers to perform experiments on tissue regeneration. Another author on the paper, Rui Yao, adds, “Our next step is to find out more about how we can vary the size of the embryoid body by changing the printing and structural parameters, and how the varying the embryoid body size leads to “manufacture” of different cell types.”
Gooooood, good.

Two of the leading scientists at the edge of the medical revolution believe that our life expectancy could start creeping up toward the triple digits.
David Agus, a professor of medicine and engineering at the University of Southern California, said at the Fortune Global Forum on Monday that he believes that with our current technology humans have the potential to regularly live into their ninth or tenth decade.
