Scientists are mapping Yellowstone's plumbing to find out why it's so explosive
The gorgeous colors of Yellowstone National Park’s Grand Prismatic Spring are among the park’s myriad hydrothermal features. (Robert B. Smith and Lee J. Siegel) What makes Old Faithful blow? That is a question scientists are trying to answer as they launch an effort to map the subterranean systems of hot water and rock that constitute the plumbing for Yellowstone’s famous geysers. Starting this week, researchers with the U.S. Geological Survey, the University of Wyoming and Aarhus Universit..>> view originalScientists Build First Chip Without Semiconductors
A group of boffins from the Applied Electromagnetics Group at the University of California San Diego have succeeded in building a microelectronic device without the incorporation of semiconductors for the first time at least in a published paper. It’s certainly possible that the feat has been been accomplished in a secret military facility or by a want to be Bond villain but this research was published this week.

Every four years, millions of American voters both abroad and at home US cast their ballot for president without going to the polls, mailing in absentee ballots to vote from afar. And a few ballots digitally make the 250-mile journey from the International Space Station to the Earth's surface. This year, Shane Kimbrough, currently the only American in space, cast his ballot from the International Space Station (ISS) Monday. Kate Rubins also voted early, submitting her ballot before returning to..>> view originalCassini space probe images a cloudy summer day on Saturn's largest moon
What does a cloudy summer day look like on Titan? As it turns out, not much like the ones on Earth.On Friday, NASA released a time-lapse video showing methane clouds swirling around the northernmost region of Saturn’s largest moon. The footage was captured by the space agency’s Cassini spacecraft in late October.Time-lapse videos can help researchers tell the difference between noise caused by cosmic rays and actual weather conditions. And by observing developing clouds on other planets, scient..>> view originalWhy all the super-buzz about the supermoon?

In humanity's distant past, perhaps as early as 100,000 years ago, anatomically modern humans who had migrated out of Africa encountered a close human relative: the Neanderthal. The two populations interbred, leaving traces in the genomes of non-African humans alive today, such that 1 to 4 percent of the human genome is Neanderthal genetic material. Our only knowledge of how these two human lineages interacted over tens of thousands of years is written in our genomes. But scientists have found ..>> view originalThis should be California's next step on climate change
California has long been recognized as a global leader in addressing climate change, and rightly so. Our aggressive policies supporting clean energy, energy efficiency and greenhouse gas limits are showing the world that a thriving economy can also be a climate-safe economy.But there’s a catch.While California’s businesses, industries and residents are doing everything possible to reduce greenhouse gas emissions, the same is not true in many places that make the products we regularly purchase. ..>> view originalTrump's victory shocks international climate negotiations
