It could happen
A 760 m.p.h. train? PayPal, Tesla and SpaceX founder Elon Musk says it could be ready within a few years. His Hyperloop system would propel passengers through a vacuum tube fueled by compressed air and induction motors.
The system would shrink the train commute from San Francisco to Los Angeles to 35 minutes, compared to the current 7.5 hours.
Musk says the system would be faster and cheaper than trains, boats, cars and planes for up to at least 900 miles, and that it would be resistant to earthquakes while generating energy through solar panels. The system would also run without emitting harmful chemicals.
Two start-up companies that have started working on this technology have raised more than $100 million each, and claim they will have functional systems within three to four years.

The Agonose Arm leaves your human hands free while providing support for your jaw, or as a head pillow. (Think airports and on airplanes.) It also professes to help you sit up straight. Although Amazon.com lists many products by Thanko, the Japanese retailer that makes the arm, the online market behemoth currently does not sell it. Meanwhile, you can always head over to Ancestry.com and investigate whether our featured novelty is any relation to the Hamburger Helper hand.
Chaitanya Karamchedu, a senior at Jesuit High School outside Portland, Oregon, may have found the long-elusive answer to converting salt water into fresh drinking water. His teacher, Dr. Lara Shamieh, told KPTV that scientists have always focused on the 10 percent of water that is bonded to the salt in the sea, not the 90 percent that is free. Experimenting with a highly absorbent polymer to isolate the saltwater, Chai found that “Sea water is not fully saturated with salt. It’s not bonding with water molecules; it’s bonding to the salt.” His discovery won a $10,000 award at Intel’s International Science Fair.

5 True or false: You can’t patent a plant.
1. True. We like to get inventive with these questions, but c’mon. 2. A. 3. John Gorrie received a patent for the first ice-making machine on May 6, 1851; Joseph Winters got his patent for the fire escape ladder on May 7, 1878. 4. B. 5. False. This right was stipulated in the Patent Act of 1930, which became law on May 23 of that year.
