U.S. physicists say they have successfully tested the first experiment sensitive enough to detect axions — hypothetical particles that some scientists think make up the dark matter holding galaxies together. The Axion Dark Matter Experiment (ADMX), which is located at the University of Washington in Seattle, represents a breakthrough in a four-decade-long search for the theoretical particles, the new study's scientists said. "It's really quite exciting to think discovery could come at any time," Gray Rybka, a physicist at the University of Washington and a co-author on the new work, told Space.com. "Now, we're really right there. When we see a blip — and we see blips periodically because of either interference or scheduled fake signal injections to make sure the thing is working — suddenly it's, this really could be it." [Dark Matter and Dark Energy: The Mystery Explained (Infographic)] Rybka said the discovery of axions could play as significant a role in … [Read more...] about Super-Sensitive Device Seeks Axions, Proposed Dark Matter Particles

AN ASTEROID bigger than a football field will shoot passed Earth tomorrow at less than half the distance of the Moon. The rock named 2010 WC9 and is expected to pass us late at night. Here's what we know about the space stone. When will Asteroid 2010 WC9 pass Earth? Asteroid 2010 WC9 is expected to pass us on Tuesday at 23:05 BST. The Catalina Sky Survey in Arizona first detected the space rock almost eight years ago on 30 November 2010. The astronomers watched it until 10 December, when it became too faint to see. But they didn’t have enough observations to track its orbit fully and to predict its return. However, last week astronomers discovered an asteroid and temporarily named it ZJ99C60, until they realised it was merely the return of asteroid 2010 WC9, hence the name. How close will it get? It will skim past us at a distance of just 26,419 miles, astronomers say. Comparatively, 2010 WC9 is not considered a “large” asteroid by any means, but a space rock of this … [Read more...] about When will the 2010 WC9 Asteroid pass Earth, how close will it get and will it be visible in the UK?
A Donald Trump foreign policy adviser pushed government agencies to review materials from the dark web in the summer of 2016 that he thought were Hillary Clinton's deleted emails, multiple sources with direct knowledge tell CNN.Joseph Schmitz approached the FBI and other government agencies about material a client of his had discovered that Schmitz believed might have been Clinton's missing 30,000 emails from her private e-mail server, sources say. The material was never verified, and sources say they ultimately believed it was fake.His push is the latest example of Trump advisers who were mixed up in efforts to find dirt on Clinton during the presidential campaign. Schmitz was one of the first people Trump named to his campaign's national security and foreign policy team. The team, showcased in a March 2016 photo, was thrown together early in Trump's successful run as he faced mounting pressure to prove his ability to pull in high-level advisers who could help prepare him for the … [Read more...] about Trump adviser played key role in pursuit of possible Clinton emails from dark web before election
THE world could end as abruptly as it began, warn experts. All it would theoretically take is for a fundamental particle - the Higgs Boson - to become destabilised, unleashing a huge energy bubble that will swallow up everything in its path, leaving nothing but a dark void. In a new study by Harvard, physicists suggest the end of our universe will come with a sudden bang rather than a slow demise. The shockwaves would severely disrupt physics, chemistry, and life as we know it. But there's no need to panic just yet – scientists say the Earth-shattering disruption may not take place for a long time. Specifically, it could occur 10x139 years from now – or 10million trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion years. The experts estimated our universe's expiration date based on its size and the speed of destruction. But they did leave an alarming footnote: the process may have already begun. In fact, we have … [Read more...] about Universe could be destroyed by huge energy bubble – and scientists warn process may have begun
At the edge of life and death is a spreading dark wave. Scientists spotted it first in rabbits. In a series of papers published throughout the 1940s, Harvard biologist Aristides Leão described finding a sudden silencing of electrical activity in the exposed brains of his unconscious experimental animals after subjecting them to injuries — applying electrical shocks, poking them with glass rods or cutting off the blood in their arteries. The "spreading depression," as he termed it, began at the injured spot within 5 minutes of the injury, before eclipsing more distant parts of the brain. Seven decades later, a paper published Feb. 15 in the journal Annals of Neurology reveals just how this process occurs in the dying brain cells of humans. [10 Mysteries of the Mind] To gather their data, the researchers set up shop in hospitals in Berlin and Cincinnati. With consent from next of kin and other legal representatives, they reported results from nine patients who died with … [Read more...] about Dying Brains Silence Themselves in a Dark Wave of ‘Spreading Depression’
