Hold up your hands in front of your face. For most people, they will be mirrored copies of each other: You can hold them palm-to-palm and they will match up, but you cannot superimpose them.
The Mystery at the Heart of Physics That Only Math Can Solve
The accelerating effort to understand the mathematics of quantum field theory will have profound consequences for both math and physics.

A Never-Before-Seen Type of Signal Has Been Detected in The Human Brain
Scientists have discovered a unique form of cell messaging occurring in the human brain that's not been seen before. Excitingly, the discovery hints that our brains might be even more powerful units of computation than we realized.

Large Dinosaurs Were Prone to Extinction Way Before The Asteroid, New Study Argues
After ruling the planet for more than 170 million years, non-avian dinosaurs were suddenly demoted from existence by the impact of a large asteroid that struck the Yucatán peninsula some 66 million years ago.

Methane Detected on Enceladus Could Actually Be a Sign of Life, Study Shows
When the Cassini-Huygens probe dove through the salty plumes belching from the interior of Saturn's moon Enceladus, it made an unexpected detection: a collection of compounds that are also associated with hydrothermal vents on Earth's ocean floor.

The system was trained entirely in simulation, in a virtual version of the real world where the robot’s small brain (everything runs locally on the on-board limited compute unit) learned to maximize forward motion with minimum energy and avoid falling by immediately observing and responding to data coming in from its (virtual) joints, accelerometers, and other physical sensors.
The robot was able to walk on sand, mud, hiking trails, tall grass and a dirt pile without a single failure in all our trials. The robot successfully walked down stairs along a hiking trail in 70% of the trials. It successfully navigated a cement pile and a pile of pebbles in 80% of the trials despite never seeing the unstable or sinking ground, obstructive vegetation or stairs during training. It also maintained its height with a high success rate when moving with a 12kg payload that amounted to 100% of its body weight.
