In San Francisco, a Hydrogen-Powered Ferry

Advocates say technology can help phase out diesel-powered boats

(Newser) - The world's first hydrogen-powered commercial passenger ferry will start operating on San Francisco Bay as part of plans to phase out diesel-powered vessels and reduce carbon emissions, per the AP . The 70-foot catamaran called the MV Sea Change will transport up to 75 passengers along the waterfront between Pier...

How Trump's Moon Plan Might Actually Pan Out

There really are plans to mine the moon

(Newser) - President Trump issued an executive order last month allowing US companies to mine the moon, but—is this really possible? Sure enough, Popular Mechanics lays out enough of the science, current projects, and history of moon-mining enthusiasm to make it seem real. "We've just been moving in a...

40-Year-Old Signal From Space Is Finally Explained

Astronomer says it was 'a natural phenomenon,' not aliens

(Newser) - In 1977, a radio telescope recorded a 72-second signal coming from the direction of the constellation Sagittarius. Stunned, the astronomer who observed it wrote "Wow!" on the readout. Since it couldn't be explained, plenty argued the signal was proof of life beyond our planet. After 40 years,...

Scientists Switch On Giant 'Artificial Sun'

They're seeking new ways to make hydrogen fuel

(Newser) - Scientists in Germany flipped the switch Thursday on what's being described as "the world's largest artificial sun" and which they hope will help shed light on new ways of making climate-friendly hydrogen fuel. The giant honeycomb-like setup of 149 spotlights—officially known as "Synlight"—in...

Scientists Make Huge Discovery, Promptly Lose It

And skeptics are wondering if they ever really made it at all

(Newser) - Last month, Harvard researchers announced they'd created the world's first and only sample of metallic hydrogen, publishing their findings in Science . Other scientists were skeptical, to say the least. And now the researchers' sample has apparently disappeared, which Gizmodo finds awfully "convenient." Scientists have been trying...

Ancient Meteorites Change Story of Earth's Water

Study: Water on Earth appears to have arrived 4.6B years ago

(Newser) - At least when it comes to life as we know it, water is a basic requirement. So a new analysis of meteorites suggesting that water could have appeared on Earth 14 million years after the start of solar system some 4.6 billion years ago—more than a hundred million...

Water on Earth Older Than Sun, Earth Itself

Water molecules more than 4.5 billion years old are in our drinking water, oceans

(Newser) - If you live and die by food and beverage expiration dates, you might not want to know how old some of our drinking water is. A study finds that 30% to 50% of the water found in our taps and oceans contains molecules created more than 4.5 billion years...

Solar Wind Brings Water to Moon: Study

Which could help in creating a colony there

(Newser) - There is water on the moon, and it comes from an unlikely source: the sun. That's the conclusion of a new study, after studying soil samples brought back from the original Apollo 11 mission, Cosmos reports. While studies dating back to 2008 have pointed to the existence of water...

MIT Creates Viruses That Mimic Photosynthesis

Innovation could create unlimited solar power

(Newser) - Scientists building complex, designer viruses in the lab may sound sort of terrifying, but what if those viruses could potentially solve the world’s energy problems? A group of researchers at MIT has fabricated an artificial virus that can be fabricated into wire-like chains that can transport solar power and...

NASA Finds Lots of Water on Moon

Rocket probe discovers large amounts of ice

(Newser) - A NASA probe has turned up water on the moon. Lots of water. “We practically tasted it with the impact,” said a geologist. The discovery—made last month after the space agency blasted the probe into the moon to study the debris—raises the chances of one day...

New Enemy in Climate Fight: Methane-Heavy Sheep Burps

Methane from livestock may cause more emissions than automobiles

(Newser) - Big oil, coal-fired power plants, automakers and now sheep: As governments look to reduce greenhouse-gas emissions, researchers are looking seriously at livestock, believed to contribute more than cars via the methane gas they belch during digestion, the Wall Street Journal reports. To that end, researchers in New Zealand are trying...
