The world’s oldest cheese has been found on the necks and chests of perfectly preserved mummies buried in China’s desert sand. Dating back as early as 1615 B.C., the lumps of yellowish organic material have provided direct evidence for the oldest known dairy fermentation method. The individuals were likely buried with the cheese so they could savor it in the afterlife. Read more
The radiation belts around Earth are loaded with dangerous protons and electrons that can damage spacecraft. Now researchers are launching experiments to see if they can clear away the high-energy particles that pose the hazard by blasting them with radio waves.
Before today, there were 1,000 confirmed exoplanets. Kepler just added 715 more! Read the details about this historic announcement.
The current generation of robots always seem so, well, robotic. Their herky-jerky movements are the result of the stiff wires and pulleys that contract and expand to move their limbs. But what if robo-muscles were more like our own; strong, yet supple, self-sufficient for long periods of time (think of the human battery life versus a robot’s) and able to make complex fine motor movements like writing or sewing.

By tracing radioactive material in the remains of a nearby exploded star, scientists have a new understanding of what happened in the star’s final moments and how similar explosions create the calcium, gold, iron and other elements spread throughout the cosmos. Read more
So you had a bad day …
Charles Darwin read Lyell's “Principles of Geology Volume 1” while he was travelling on the Beagle, and when he returned to England they became close friends. Darwin vents to Lyell in this letter from 1861.

Happy Birthday Charles! And to the rest of you - Happy Darwin Day!
i love this.
