Blinded by the light of a falling meteor, David has a devastating car accident, leading to a profound discovery: an extra-terrestrial organism that may contain the secret of life itself. When David goes missing for two days, Annabelle searches for her father only to discover him wandering the forest, without so much as a scratch. David’s mysterious reappearance draws the attention of federal authorities and gives Annabelle reason to doubt his sanity. But David has a new sense of purpose, fueled by nightmarish visions. Driven by what he believes is an otherworldly purpose, David must convince Annabelle to believe him and complete his task before government agents can stop him, and before the world destroys itself.

A laser set to begin live-fire tests at White Sands Missile Range, New Mexico, in January uses rare earth minerals. It was developed by General Atomics Aeronautical Systems Inc. of Poway, Calif., the company that produced the revolutionary MQ-1 Predator drone. Its precise power levels are classified, but Michael Perry, the company’s vice president for laser programs, said the experimental weapon’s beam is in the 150-kilowatt class. That’s more than 100 times the power needed to heat an electric oven to 350 degrees.

The General Atomics laser is five times more powerful than the only laser the military has fielded, the 30-kilowatt-class Laser Weapon System, a fiber laser the Navy developed that has knocked down small drones and crippled small boat swarms in tests at short range. That laser was installed on the USS Ponce, an Afloat Forward Staging Base deployed to the Middle East, in 2014. This past October, the Navy awarded Northrop Grumman a $53 million contract to develop a more powerful shipboard laser.

Bulk lasers use slabs or strips of rare earth minerals — ytterbium, for example — as their gain medium. Fiber lasers “gang” fiber-optic cables together as the gain medium.

Engineer Robert Grass says that though we believe information is here forever, it’s actually fragile. Hard drives and physical sources of information, like books, decay over time. In a video for the BBC, Grass describes his quest to find a method of preserving information that could be stable for millions of years. The secret is DNA.

In 2012, research showed that you could translate a megabyte (MB) of information into DNA and then read it back again. DNA has a language of its own, and is written in sequences of nucleotides (A, C, T, and G). Think of it as similar to binary, which breaks information down into ones and zeros.

And DNA has the advantage of being able to put an enormous amount of information in a tiny space. Theoretically, one gram of DNA could hold 455 exabytes of information. That’s “enough for all the data held by Google, Facebook and every other major tech company, with room to spare”, according to New Scientist.

A U.S. science satellite slated to launch to Mars in March has been grounded due to a leak in a key research instrument, NASA said on Tuesday, creating uncertainty about the future of a widely anticipated effort to study the interior of the planet.

The spacecraft, known as InSight, was designed to help scientists learn more about the formation of rocky planets, including Earth.

The cancellation raises questions about the future of the research effort, as it will be another two years before Earth and Mars are favourably aligned for a launch. NASA has not said if it will have funding for the program, which was capped at $425 million US.
