This Breakthrough Could Fix the Fatal Flaw in Fusion Reactors

Image
  A new supercomputer model could help scientists reach nuclear fusion energy. Tokamak reactors are plagued by electromagnetic blobs that constrict or cool plasma. A full simulation lets scientists safely analyze the risk factors and potential solutions. In the long road to nuclear fusion, scientists continue to confront one of the more prominent (and literal) bumps: edge localized modes (ELMs). These blobs form at the edge of a tokamak’s plasma swirl, caused by the interaction of the powerful, containing magnetic field and the sun-hot plasma. In the past, scientists have volunteered several solutions, including pulsating radio waves. But now, researchers from the Max-Planck-Institut für Plasmaphysik (IPP) in Germany have what they say is the first simulation of how ELMs form—making it easier to model the risks and the potential solutions. “After extensive previous work, it has now been possible for the first time by means of computational simulations to identify the trigger responsibl

Fights Erupt During 'Jews for Trump' Rally in Manhattan

Image
  Political tensions over the upcoming presidential election escalated on New York City’s streets Sunday, as supporters of President Donald Trump clashed with counterprotesters during a day of demonstrations. Eleven people were arrested, police said, during skirmishes between opposing sides in Manhattan, where Rudy Giuliani, the president’s personal lawyer and the city’s former mayor, encountered protesters targeting a caravan of cars organized by a group that identifies itself as Jews for Trump. All have been released except for a 36-year-old man who threw eggs in the faces of two police officers, police said. In one video, Giuliani could be seen in the passenger side of a vehicle with the window rolled down as anti-Trump protesters screamed at him. In an interview, Giuliani said that he had encountered the caravan and the protesters while driving down Fifth Avenue after taping his radio show. “I would love to have had a campaign commercial of it and put it on in the middle of America

Qatar airport accused of invasive passenger strip-search as it sought mother of newborn baby found in toilet

Image
  Australian officials have raised “serious concerns” with Qatari authorities after airline staff were accused of invasively strip-searching women, including 13 Australians, having taking them off a flight from Doha to Sydney. The events of Friday, 2 October, came to light in a report by Australian broadcaster Seven News on Sunday night. Flight QR908 to Sydney was due to leave Hamad International airport at 8.30pm but was delayed for four hours after a newborn infant, believed to have been prematurely born, was found in a terminal bathroom.  Women on board the flight were ordered to disembark without being told why and reportedly forced to strip and undergo an invasive medical examination nearby. After their return to the plane it was allowed to depart. A spokesperson for Australia’s Department of Foreign Affairs and Trade told ABC it had raised the incident with Qatari officials. “We have formally registered our serious concerns regarding the incident with Qatari authorities and have

Putin pours cold water on Trump's Hunter Biden hopes

 If President Trump were looking for a little last-minute boost from Russian President Vladimir Putin, Putin had nothing for him on Sunday. In televised remarks on state TV, Putin "took the time to knock down what he made clear he regarded as false allegations from Trump about the Bidens," Democratic nominee Joe Biden and his son Hunter, Reuters reports. Putin said Trump's story about Hunter Biden getting money from the widow of a former Moscow mayor was news to him, even though Trump tried to tie Putin to the alleged payment. In Ukraine, Putin said, Hunter Biden "had or maybe still has a business, I don't know. It doesn't concern us. It concerns the Americans and the Ukrainians." And regarding the money Hunter Biden made working for a Ukrainian company, he added, "I don't see anything criminal about this, at least we don't know anything about this (being criminal)." U.S. intelligence has determined that Russia is secretly working to bo

'Murder hornet': First nest found in US eradicated with vacuum hose

Image
  The first nest of Asian giant hornets found in the US has successfully been destroyed by scientists. The nest, in the state of Washington, was found by putting tracker devices on the hornets and it was sucked out of a tree using a vacuum hose. The invasive species insects, known as "murder hornets", have a powerful sting and can spit venom. Related: How scientists extinguished a den of murder hornets They target honeybees, which pollinate crops, and can destroy a colony in just a matter of hours. The nest in Washington was found when entomologists, scientists that study insects, used dental floss to tie tracking devices to three hornets. The nest of around 200 insects was then discovered in the city of Blaine close to the Canadian border. On Saturday, a crew of scientists wearing protective suits vacuumed the insects from the tree, which will now be cut down to remove any further nests. Asian giant hornets are among the world's largest wasps - the queens can reach over

‘Catastrophic’ shark attack critically injures Australian spearfisher, officials say

A 59-year-old man spearfishing near the Great Barrier Reef in Australia suffered “catastrophic” injuries Sunday in a shark attack, officials say. Paramedics airlifted the man from Britomart Reef to a Townsville hospital, where he’s listed in critical condition, after the 12:30 p.m. attack, The Guardian reported. “There was obviously evidence of a very significant shark bite to the patient’s upper thigh, pelvic region,” said David Humphreys, a doctor with LifeFlight Australia, NBC News reported. Britomart Reef, part of Great Barrier Reef, is a popular fishing destination, 9 News reported. The man had been spearfishing with a friend when a shark attacked him.
