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.

When you rest your brain, your brain activates a network that we call the default network. This network only becomes active when you step away from your work or cognitively-demanding tasks.

"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."

SatVu's cameras are so precise they can show the capacity of airfields, whether a ship is being loaded and even when individual pumps on a nuclear reactor are switched on.

"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."

The illusion contains nine purple dots against a blue background. When those of us with full color vision focus on one dot, it appears more purple while the rest seem to shift to blue.

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.

Methane is better suited for reusable engines because they leave less behind sooty residue than kerosene, which SpaceX uses on the Falcon 9 rocket.

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.
