Is a series on threats posed by #ArtificialIntelligence.

Intro.

Their niche is pulse detonation engines. http://www.

These technologies sound like something out of a sci-fi movie, but these companies are turning them into a reality.

Suppose you throw some object near the surface of the Earth. If the only significant force on the object is the constant downward gravitational force, we call this “projectile motion.” Yes, that tennis ball you loft across the room is projectile motion. Flipping a coin—the center of mass is projectile motion. As you can probably guess, a dude jumping on a moving trampoline is also an example of projectile motion.

For these kinds of motions, the following must be true:

Scientists researching the microbial life on volcanic vents uncovered more incredible ocean landscapes from the seafloor off the coast of California. Just check this out:

An international team, led by University of Georgia associate professor Samantha Joye, set out to explore sites in both the northern and southern Gulf of California, analyzing how microorganisms live in the hot waters by the vents. These images come from the ROV SuBastian, a remotely operated sub that can take samples and image the area around these vents, operated from the Schmidt Ocean Institute’s research vessel, Falkor.

The button mushroom in your local grocery store is a visible outpost of a largely hidden, alien-like kingdom that rules all life on land: fungi. Annamaria Talas takes a look.

University of Central Florida researchers have developed a way to control the speed of light. Not only can they speed up a pulse of light and slow it down, they can also make it travel backward.

The creatures “can reversibly enter a state where outwardly observable signs of metabolic activity are paused under conditions that are essentially incompatible with life.”
