Building the first universal quantum computers for business and science
IBM Q is an industry-first initiative to build commercially available universal quantum computers for business and science. While technologies like AI can find patterns buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen and the number of possibilities that you need to explore to get to the answer are too enormous ever to be processed by classical computers.
Rapid rise in methane emissions in 10 years surprises scientists
Emissions of the powerful greenhouse gas methane have surged in the past decade, threatening to thwart global attempts to combat climate change.
Scientists have been surprised by the surge, which began just over 10 years ago in 2007 and then was boosted even further in 2014 and 2015. Concentrations of methane in the atmosphere over those two years alone rose by more than 20 parts per billion, bringing the total to 1,830ppb.
This is a cause for alarm among global warming scientists because emissions of the gas warm the planet by more than 20 times as much as similar volumes of carbon dioxide.
Deepest X-ray Image Ever Reveals Black Hole Treasure Trove
An unparalleled image from NASA’s Chandra X-ray Observatory gives astronomers the best look yet at the growth of black holes over billions of years beginning soon after the Big Bang. This is the deepest X-ray image ever obtained, collected with about 7 million seconds, or eleven and a half weeks, of Chandra observing time.
About 70% of the objects in the new image are supermassive black holes, which may range in mass from about 100,000 to ten billion times the mass of the Sun. Gas falling towards these black holes becomes much hotter as it approaches the event horizon, or point of no return, producing bright X-ray emission.
Researcher Develops Completely Explosion-Proof Lithium Metal Battery With 2X Power Of Lithium Ion
Charging the battery causes positively charged ions to flow through the liquid from the negative side to the positive side. As you use the battery, the ions flow in the opposite direction. It’s a serviceable solution, but the electrolyte is extremely flammable and sensitive to being poked—they can explode when pierced. This is called thermal runaway, which is what the Galaxy Note 7’s batteries experienced.
Zimmerman’s ionic battery trades the flammable liquid for a piece of plastic film to serve as the electrolyte. It isn’t prone to overheating and catching fire. You can even take a lighter to it and it still won’t catch fire. The same goes for piercing it, cutting it, or otherwise destroying the battery in some other physical manner.
