Trace amounts of uranium exist in seawater, but efforts to extract it for nuclear power haven't produced enough to make it a viable source for countries that don't have uranium mines. A practical method for extracting that uranium, which produces higher quantities in less time, could help make nuclear power a viable part of the quest for a carbon-free energy future. Concentrations are tiny, on the order of a single grain of salt dissolved in a liter of water, says Yi Cui, a professor of materials science and engineering and of photon science at Stanford University and coauthor of a new paper in Nature Energy . But the oceans are so vast that if we can extract these trace amounts cost effectively, the supply would be endless. Bridging the gap Alternative forms of energy like wind or solar are critical for reducing the world's carbon emissions.

New work from Carnegie's Stephen Elardo and Anat Shahar shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created. Their findings are published by Nature Geoscience.

The lab teamed up with Taiwan’s Industrial Technology Research Institute (ITRI) to use the battery to power a motorbike, winning a 2016 R&D 100 Award for their groundbreaking results. This original version, though impressive, involved an expensive electrolyte. The newest version, on the other hand, implements a urea-based electrolyte and is an estimated 100 times cheaper than the 2015 model. It also has higher efficiency and a charging time of just 45 minutes. Dai noted that the cost difference between the two batteries is “like night and day.” Dai and Angell's work marks the first time urea has been used in a battery. The low-cost battery is even more impressive in a day and age when the demand for renewable technologies continues to grow. Energy storage has proved a massive challenge for solar power and other renewables, with users requiring a reliable way to store power when their systems aren't generating energy.

A re-examination of the iconic John Constable work, Salisbury Cathedral from the Meadows, has found that the original 1831 exhibited version of the painting did not have a rainbow – and that it was added later to correspond with the time of his best friend's death over a year later.

Emma Sims 3 min 21 sec ago Space Youll remember the controversy when Pluto got demoted to dwarf planet status in 2006. Now it seems it could be set to rejoin the ranks of planets in our solar system, along with over 100 others, including Earth’s moon, Jupiter’s moon Ganymede, and Titan and Enceladus, which orbit Saturn and Europa. A team of six NASA scientists, headed by Alan Stern, primary investigator of NASA’s New Horizons Mission to Pluto, have instigated a proposed change to the definition of what constitutes a planet. Their renewed position hinges on one key point : they believe that in order to constitute planets, celestial bodies in the Solar System do not need to orbit the Sun. The change shifts emphasis onto the physical properties of the cosmic bodies themselves, rather than comportment with external bodies.

Twenty years ago Japanese carmaker Toyota unveiled the first version of its hybrid gas-electric car called Prius. By the beginning of 2017, counting all subsequent models, Prius became the best-selling hybrid car in the world with close to 4 million sold. Its latest model, with a battery-charging solar roof, was just unveiled in Japan. VOA’s George Putic reports.

Because the Trojans are remnants of the primordial material that formed the outer planets, they hold vital clues to deciphering the history of the solar system. Lucy, like the human fossil for which it is named, will revolutionize the understanding of our origins, said the principle investigator of the mission, Harold F. Levison. Associate administrator at NASA's Science Mission Directorate in Washington, Thomas Zurbuchen, notes that this kind of asteroid has never been studied before. This is what Discovery Program missions are all about,” Zurbuchen noted, “boldly going to places we've never been to enable groundbreaking science. It is estimated that it will take Lucy six years to get there; once it arrives, it will spend 20 months mapping and studying the asteroid. The other mission, which will launch in October 2023, involves another robotic spacecraft named Psyche, which, after an Earth gravity assist maneuver in 2024, will shoot past Mars in 2025, and reach the asteroid by 2030.

This action is the reason behind that cute hiccup sound we all know and love. So this guy was basically suggesting that this entire process can be stopped just by thinking about it. My Experience and How to Do It I, of course, instantly perked up and continued to listen. He told me to send calming thoughts to my diaphragm — the muscle right underneath your lungs, responsible for inhalation and inspiration. It’s also right in the area of your solar plexus (for all you yogis out there). He said to focus on that muscle and picture it calming down. I closed my eyes, and tried it. And it worked. No more than 10 seconds later, I opened my eyes, and low and behold — no more hiccups. He laughed and said, “pretty good party trick,” and then walked away. I was floored! I always knew that our minds were powerful, but now I had actual proof. Try this trick the next time you have a fit of hiccups.
