• Q&A: How Ridgecrest Earthquakes Helped Scientists with ShakeAlert

    U.S. Geological Survey geophysicist Sarah Minson was in the thick of efforts to develop an earthquake warning system in California when a series of major temblors struck the sparsely populated community of Ridgecrest in the Mojave Desert this summer. The largest, a magnitude 7.1 quake on July 5, was the biggest to hit the state in decades. The Mercury News asked her about her work — and how this month’s big quakes is helping scientists refine California’s fledgling earthquake alert system.

  • Assessing Handheld Explosives Trace Detectors

    Individuals who carry explosives or have been involved in bomb making are likely to be contaminated with trace explosives, microscopic particles invisible to the naked eye. Without the right equipment, detecting trace explosives can be challenging for responders and security personnel. Handheld explosives trace detectors (ETDs) can be used to complement bomb-sniffing canines, which are still the gold standard in trace explosives detection. These detectors can be used to find trace explosives on individuals, hopefully preventing a dangerous incident.

  • Americans Focus on Responding to Earthquake Damage, Not Preventing It, Because They’re Unaware of Their Risk

    On July 4 and 5, two major earthquakes, followed by several thousand smaller ones, struck Southern California. Their size and the damage they caused captured attention around the country. What tends to get much less notice from the public is what can be done to prevent catastrophic damage from big quakes.

  • Gaining Competitive Advantage for the U.S. in the Gray Zone

    The United States is entering a period of intensifying strategic competition with several rivals, most notably Russia and China. U.S. officials expect this competition to be played out primarily below the threshold of armed conflict, in what is sometimes termed the gray zone between peace and war. The United States is ill prepared and poorly organized to compete in this space, but the United States can begin to treat the ongoing gray zone competition as an opportunity more than a risk.

  • New Sensor Improves Earthquake Response Efforts

    The recent massive southern California earthquakes shut down Ridgecrest Regional Hospital throughout the 4 July holiday weekend while the tiny town of Ridgecrest assessed the damages. Researchers developed a new optical sensor which could speed up the time it takes to evaluate whether critical buildings like these are safe to occupy shortly after a major earthquake.

  • How Cyber Weapons Are Changing the Landscape of Modern Warfare

    In the weeks before two Japanese and Norwegian oil tankers were attacked, on 13 June, in the Gulf of Oman—acts which the United States attributes to Iran—American military strategists were planning a cyberattack on critical parts of that country’s digital infrastructure. On 20 June, the United States launched a cyberattack aimed at disabling Iran’s maritime operations. Then, in a notable departure from previous Administrations’ policies, U.S. government officials, through leaks that appear to have been strategic, alerted the world, in broad terms, to what the Americans had done.

  • Helping first responders deal with dirty bombs

    If a radiological dispersal device (RDD), or “dirty bomb,” ever explodes in the United States, emergency crews may be better prepared because researchers have developed a new simulator, which show first responders what an optimal response to an RDD would look like.

  • Radiation in Parts of the Marshall Islands Is Far Higher than Chernobyl, Study Says

    Think of the most radioactive landscapes on the planet and the names Chernobyl and Fukushima may come to mind. Yet research published Monday suggests that parts of the Marshall Islands in the central Pacific, where the United States conducted 67 nuclear tests during the Cold War, should be added to the list.

  • Climate Change Is Driving Many California Wildfires

    Against a backdrop of long-term rises in temperature in recent decades, California has seen ever higher spikes in seasonal wildfires, and, in the last two years, a string of disastrous, record-setting blazes. This has led scientists, politicians and media to ponder: what role might warming climate be playing here?

  • Cyberattack Attribution and the Virtues of Decentralization

    In the midst of rising tensions between the United States and Iran over tanker attacks and Iran’s downing of a U.S. drone, reports emerged that U.S. Cyber Command had launched a responsive cyber operation against a group linked to the Iranian Revolutionary Guard Corps. As cyber operations by both states heat up, non-governmental actors may play pivotal roles, not just as potential victims and collateral damage from states’ actions, but also as accusers of states.

  • It Sure Looks Like Jeffrey Epstein Was a Spy—but Whose?

    In terms of scandals, the sordid saga of Jeffrey Epstein has it all. Mysterious gaudy fortunes. Jet-setting debauchery. Lots of pretty girls—including very young girls. Sex and more sex, not necessarily legal or consensual. Add a battalion of VIPs, including billionaires, A-list celebrities, royalty and no less than two American presidents. The only thing missing was espionage — and it’s not missing anymore.

  • Do Patents Protect National Security?

    On 12 June, the Wall Street Journal broke the story that Chinese firm Huawei Technologies Co. had asserted more than 200 patents against Verizon Communications Inc., reportedly demanding more than $1 billion in licensing fees. On its face, this would seem to be a private patent dispute. But, in fact, it is an important turn of events for national security: The Verizon-Huawei dispute contradicts a view espoused by many experts, and even the Trump administration, about the relationship between national security and intellectual property rights such as patents.

  • Iranian Nuclear Facility “Has Never Been Repurposed” as Promised under 2015 Nuclear Deal

    Iran’s underground Fordow uranium-enrichment facility has not followed the 2015 nuclear deal. Apparently, it has “never been repurposed” in that “everything required to enrich uranium to weapons grade could be quickly reconstituted in the underground portion of the facility,” continued the report.

  • How Israel and Iran Joined Forces to Kill a Nuclear Weapons Program

    At dawn on 30 September 1980 four American-made F-4E Phantom jets screamed low over central Iraq, each laden with air-to-air missiles and three thousand pounds of bombs. The skimming Phantoms climbed briefly to higher altitude so as to appear on Iraqi radars, before ducking back down to hit the deck. But while two decoy Phantoms maintained their trajectory towards Baghdad, the other two veered southwards towards the real target: Iraq’s Osirak light-water nuclear reactor. The jets were undertaking the first air-strike against a nuclear reactor, and the first preemptive air-strike attempting to prevent a country from developing nuclear weapons capability. Now, the famous Israeli Operation Opera that destroyed the Osirak reactor was still nine months away. The Phantoms soaring towards the reactor in 1980 belonged to the Iranian Air Force.

  • YouTube removes audio copies of neo-Nazi books

    James Mason’s neo-Nazi manifesto, Siege, has inspired a generation of neo-Nazis since it was first published as a single volume in 1992. The book sparked a violent online subculture called Siege Culture, devoted to Mason’s calls for independent terror cells to carry out a race war. YouTube has now taken down uploads of both Siege and the neo-Nazi book The Turner Diaries.
