NASA is refocusing its moon exploration strategy by abandoning the Gateway project and planning to build a $20 billion moon base.
Researchers have resurrected 'dead' bacterial cells by replacing their defunct DNA with the working genome of another species. This technique could open the door to re-engineered microbial life imbued with useful properties, such as the ability to make drugs or biofuels.
"We are building qualification panels to send to our first customers that will demonstrate that these two dimensional photovoltaics have the efficiency and the durability to survive space," Shearer said. "We're going to prove that out at a larger scale over this next year, and in doing so, we are refining the processes necessary to make every single layer of our photovoltaic to produce these in a roll to roll fashion."
"In his journey from the front lines to the emergency room to the stars, he has found purpose in being a part of something larger than himself - and he has shown a determination to leave the world better than he found it."
Fusion power seeks to use the energy released from the fusing of atoms to generate electricity. Humans have known how to fuse atoms for decades, from the hydrogen bomb to various fusion devices built in labs.
The body of the robotic fingers is built from polyglycerol sebacate, a synthetic elastomer made from glycerol and sebacic acid. Glycerol is a byproduct of biodiesel production while sebacic acid is derived from castor oil, and both of them are plant-based. Polyglycerol sebacate is safe since it is already used in medical implants because the body can absorb it without a toxic response.
Faltings was awarded the prize for work proving central results in the theory of algebraic equations linking whole numbers together. The prize highlights Faltings's work in 1983 on the theory of Diophantine equations, which are equations involving sums and powers of unknown numbers for which the solutions have to be rational - meaning they can be written as a fraction of two whole numbers, or integers.
