LOS ANGELES, Kalifornia (PNN) - March 17, 2015 - Hydrogen powered cars are slowly accelerating in popularity with boosts from infrastructure development and car manufacturers. But getting eco-friendly hydrogen is still a bit of a challenge. Right now, a lot of hydrogen is produced through mixing steam and natural gas. An alternative to using natural gas is electrolysis, using an electric current to pull apart the oxygen and hydrogen in water, but current methods use way too much energy to make it worth it. Scientists around the country are working on making the process simpler, using AAA batteries, chemical reactions and other methods to make hydrogen a greener choice.

SINGAPORE (PNN) - March 16, 2015 - Researchers at the University of Southampton and the Nanyang Technological University (NTU) in Singapore have found that fiber optics can be used to build low-power, high-bandwidth artificial neurons that mimic their biological counterparts.

MONTREAL, Quebec, Canada (PNN) - March 16, 2015 - When Neptune launched its grand idea for upending the smart phone ecosystem, many responses boiled down to: Huh?

Sure, the idea sounded downright radical: Instead of a smart phone streaming to devices like a smart watch, the Neptune Hub and Pocket were created with the opposite relationship in mind. There was Hub, a smart watch powerful enough to run apps, take calls, and send messages; and there was Pocket, a relatively dumb screen that fit in your pocket, like a smart phone, but was little more than an input device. Many people didn’t get it. “Most of the negativity was from people that don’t see this as a first start,” says Simon Tian, Neptune’s 20-year-old founder. “They thought we were just going to stop at the pocket screen.”

BEAVER COUNTY, Pennsylvania (PNN) - March 3, 2015 - A vending machine operated by a candidate for Beaver County Sheriff that distributes firearms ammunition is raising some eyebrows.

WAIHOPAI VALLEY, New Zealand (PNN) - March 8, 2015 - Near the heartland of New Zealand’s renowned wine country, there is a place that visitors are not allowed to go. The peculiar large white domes that protrude from the earth in the Waihopai Valley are surrounded by razor wire and shrouded in secrecy.

But now, newly revealed documents from the Amerikan Gestapo National Security Agency division whistleblower Edward Snowden shine a light on what is behind the security perimeter. The buildings there are crammed with sophisticated NSA spying technology, used by New Zealand to sweep up text messages, emails, phone calls, and other communications in bulk across the Asia-Pacific.
