Finally, the future that children of the ’80s want to see is on its way. NASA is working on its very own Transformer — a bot called Shapeshifter, made up of smaller robots which can combine into different configurations to roll, swim, fly, and float.

Shapeshifter is a prototype for exploring Saturn’s moon Titan. Before it ended its mission by burning up in Saturn’s rings, the Cassini probe flew by Titan more than one hundred times, observing the moon which is surprisingly similar to Earth. It has rivers, lakes, and rain, but instead of being made of water, these bodies are made of liquid methane and ethane. On Earth, these are gases, but in the freezing temperatures of Titan, they are liquid. Cassini collected mapping data of the surface, and scientists have been keen to discover more since then.

“We have very limited information about the composition of the surface [of Titan],” Ali Agha, Principal Investigator at NASA’s Jet Propulsion Laboratory (JPL), said in a statement. “Rocky terrain, methane lakes, cryovolcanoes — we potentially have all of these, but we don’t know for certain. So we thought about how to create a system that is versatile and capable of traversing different types of terrain but also compact enough to launch on a rocket.”

Tonight—just like every night—the pursuit of E.T. perseveres in Hat Creek, California.

There, in the midst of the Cascade Mountains, the faint buzz of the Allen Telescope Array hums on a secluded and scrubby field where jackrabbits wander and rattlesnakes roam.

Since 2007, the array’s 42 radio dishes have scanned the skies for signals from alien civilizations. Detecting one is the longest of long shots. So far, nothing suggesting an extraterrestrial intelligence has been found. Here at Hat Creek, a close encounter with a bear seems more likely.

Raphael Mechoulam, an Israeli organic chemist and professor of medicinal chemistry at the Hebrew University of Jerusalem, remembers the letdown after his groundbreaking discoveries surrounding the structure of the cannabis compounds CBD and THC in 1963 and 1964, followed by clinical tests with CBD published in 1980.

“Not much happened,” Mechoulam said, noting that it would take more than 30 years before his clinical work on using CBD, or cannabidiol, to treat epilepsy became widely accepted. Greenwich Biosciences, which is owned by GW Pharmaceuticals, was able to develop the first cannabis-derived drug that built on Mechoulam’s research. The drug, Epidiolex, treats seizures associated with two rare forms of epilepsy and was approved by the FDA only last year.

But even as his work laid the foundation for the modern cannabis industry and for understanding how cannabis interacts with the human body, a white whale eluded research: cannabis acids, which are compounds that are produced in the plant when it is alive and may be more potent than their better-known derivatives, such as CBD and THC.

WASHINGTON (Reuters) — The U.S. Federal Aviation Administration late on Friday said it would require operators of some Boeing (BA.N) 737 NG jetliners to conduct inspections for structural cracks and make repairs as needed following the discovery of cracks on a small number of planes.

The FAA said Boeing notified it of the issue “after it discovered the cracks while conducting modifications on a heavily used aircraft.” Subsequent inspections “uncovered similar cracks in a small number of additional planes.” Boeing said on Friday it has been in contact with 737 NG operators about a cracking issue, but added that “no in-service issues have been reported.”

Neither the FAA nor Boeing immediately said how many planes were impacted by the required inspections.
