    In November 2016, astronomers watched a young star some 1,500 light-years away from Earth belch out an explosion of plasma and radiation that was roughly 10 billion times more powerful than any flare ever seen leaving Earth's sun. This sudden stellar eruption may be the most luminous known flare ever released by a young star — and it could help scientists better understand the still-murky process of star formation. "Observing flares around the youngest stars is new territory and it is giving us key insights into the physical conditions of these systems," Steve Mairs, an astronomer and lead author of the study, said...

    Border guards seized a British lorry on its way to make a delivery to the Iranian military - after discovering it was packed with radioactive material that could be used to build a dirty bomb. The lorry set off from Kent on its way to Tehran but was stopped by officials at a checkpoint on Bulgaria's northernborder with Romania after a scanner indicated radiation levels 200 times above normal. The lorry was impounded and the Bulgarian Nuclear Regulatory Agency (NPA) was called out. On board they found ten lead-lined boxes addressed to the Iranian Ministry of Defence. Inside each box...

    An optimal shielding configuration has been realized during the phase I study, and it is referred to as a Magnetospheric Dipolar Torus (MDT). This configuration has the singular ability to deflect the vast majority of the GCR including HZE ions. In addition, the MDT shields both habitat and magnets eliminating the secondary particle irradiation hazard, which can dominate over the primary GCR for the closed magnetic topologies that have been investigated in the past. MDT shielding also reduces structural, mass and power requirements.... During the phase I study MSNW developed 3-D relativistic particle code to evaluate magnetic shielding of GCR...

    PITTSBURGH (KDKA) – Can cellphones really cause cancer? It’s been a question that’s dogged researchers for years. However, a group of experts say the results of some tests are pretty surprising. Millions of people constantly call, text, click, take pictures and play on cellphones. Even the top cellular radiation researchers from around the world have a hard time untethering. But, they gathered recently in North Carolina to talk about cellphone concerns and whether they really do increase the chances of developing cancer. The panel voted that the results from years of testing on mice and rats were more significant than...

    North Koreans who defected but once lived near a nuclear testing site in the rogue nation now believe they are experiencing the dangerous effects of exposure to harmful radiation — and it's triggered severe health problems, according to a report published Sunday. "So many people died we began calling it 'ghost disease,'" Lee Jeong Hwa, who in 2010 escaped her home in Kilju County where the nuclear testing site Punggye-ri is located, told NBC News. "We thought we were dying because we were poor and we ate badly. Now we know it was the radiation." Lee isn’t the only defector...

    Russia's meteorological service has reported “extremely high pollution” of a radioactive isotope in the Urals near a facility that previously suffered the third worst nuclear catastrophe in history. The news bolsters international reports that a ruthenium-106 leak originating in the Urals sent a radioactive cloud over Europe. Greenpeace Russia has said it will ask the prosecutor general to investigate the possible cover-up of a nuclear accident. Rosatom, Russia's state nuclear company, said in a statement to The Telegraph on Tuesday there had been "no unreported accidents" and the ruthenium-106 emission was "not linked to any Rosatom site". Its Mayak facility,...

    Space Age, scientists have understood how beyond Earth’s magnetic field, space is permeated by radiation. This includes Galactic Cosmic Rays (GCRs), Solar Particle Events (SPEs) ... NASA is able to protect crews from SPEs by advising them to seek shelter in more heavily shielded areas of the station... GCRs are more of a challenge. These energetic particles, which are primarily composed of high-energy protons and atomic nuclei, can come from anywhere within our galaxy and are capable of penetrating even metal. To make matters worse, when these particles cut through material, they generate a cascade reaction of particles, sending neutrons,...

    One of the techniques currently under development that it is following is NMN, a compound expected to enter clinical trials after it was shown to rejuvenate elderly mice in laboratory tests. It is also considering making more advanced tweaks or alterations to the DNA of its astronauts, although the moral implications of such a radical step will need to be addressed. This includes epigenetic modifications, which alter the way genes are read by the body without making changes to the underlying DNA code. Using such a technique would allow Nasa's scientists to turn up the volume on one genetic instruction...
  • Generating terahertz radiation from water makes 'the impossible, possible'

    09/29/2017 9:29:56 AM PDT · by Red Badger · 13 replies ^ | 09-28-2017 | Provided by: University of Rochester
    Xi-Cheng Zhang has worked for nearly a decade to solve a scientific puzzle that many in the research community believed to be impossible: producing terahertz waves—a form of electromagnetic radiation in the far infrared frequency range—from liquid water. Now, as reported in a paper published in Applied Physics Letters, researchers at the University of Rochester have "made the impossible, possible," says Zhang, the M. Parker Givens Professor of Optics. "Figuring out how to generate terahertz waves from liquid water is a fundamental breakthrough because water is such an important element in the human body and on Earth." Terahertz waves have...

    Radiation leak at North Korean nuclear test site 'inevitable', says Chinese expert By Neil Connor, beijing 5 SEPTEMBER 2017 A radiation leak at the site of North Korea’s massive bomb test is “inevitable”, a Chinese nuclear weapons expert warned, after authorities in China reported that the mountain where the explosion took place had collapsed. China’s Earthquake Network Centre said a second 4.6 magnitude ‘earthquake tremor’ happened eight minutes after Sunday’s initial explosion, which measured 6.3 magnitude. Authorities in China said the tremor could be a result of a “cave in”, a potentially devastating collapse of the mountain at the Punggye-ri...

    The single mountain under which North Korea most likely conducted its five most recent nuclear bomb tests, including the latest and most powerful on Sunday, could be at risk of collapsing, a Chinese scientist said. By measuring and analysing the shock waves caused by the blasts, and picked up by quake stations in China and neighbouring countries, researchers at the University of Science and Technology of China in Hefei, Anhui province, said they were confident that they were all carried out from under the same mountain at the Punggye-ri test site. The team from the seismic and deep earth physics...
