Between the summer of 1665 and the spring of 1667, Isaac Newton developed his theories on calculus, optics, and the laws of motion and gravity. He was quarantining during the Bubonic Plague and found the extra time on his hands gave him the freedom to pursue intellectual endeavors his day-to-day duties may have otherwise squandered.

Nearly 400 years later, history could be repeating itself.

With decades of work at the intersection of time, space, and elementary particles under his belt, Stephen Wolfram believes he’s close to discovering how the universe works—or, at least, the fundamental law of physics that makes all of our other laws of physics tick. So the 60-year-old computer scientist, businessman, and physicist has launched “The Wolfram Physics Project” to crowdsource that work with some of the best minds in the world.

Humans and all other living things have DNA, which contains hereditary information. The information in your DNA gives your cells instructions for producing proteins. Proteins drive important body functions, like digesting food, building cells, and moving your muscles.

Your DNA is the most unique and identifying factor about you—it helps determine what color your eyes are, how tall you are, and how likely you are to have certain health problems. Even so, over 99% of DNA sequences are the same among all people. It is the remaining 1% that explains much of what makes you, you!

DNA is arranged like two intertwined ropes, in a structure called a double helix (see figure 1). Each strand of DNA is made of four types of molecules, also called bases, attached to a sugar-phosphate backbone. The four bases are adenine (A), guanine (G), cytosine ©, and thymine (T). The bases pair in a specific way across the two strands of the helix: adenine pairs with thymine, and cytosine pairs with guanine.

A decade in the making, NASA and SpaceX have set May 27 as the target launch date for the first crewed space mission to launch into orbit from U.S. soil since the retirement of the space shuttle in 2011.

NASA astronauts Doug Hurley and Bob Behnken, two veterans of the shuttle program, will ride SpaceX’s Crew Dragon spacecraft into orbit on top of a Falcon 9 rocket from pad 39A at NASA’s Kennedy Space Center in Florida. That’s the same historic launch facility used by the last space shuttle flight.

Liftoff time on May 27 is expected to be around 4:32 p.m. EDT (2032 GMT), when the Earth’s rotation brings the launch pad under the orbital plane of the International Space Station.
