• Humans need to learn to co-exist with wildfires. Here’s how we can do it.

    As housing developments creep into wild and natural areas, proactive planning can reduce the risk of harm in the face of fire. Urban planning for wildland-urban interface (WUI) areas now centers on creating and maintaining development and building codes that incorporate the home ignition zone (HIZ) principles. These codes promote practices such as using fire-resistant building materials for siding and rooftops; maintaining “defensible space” by clearing dead leaves from rooftops, gutters and decks; trimming trees and removing vegetation that can fuel fires during the dry season; and governing subdivision design to include multiple routes by which residents can flee and fire-fighting equipment can enter. Collectively, these types of policies are loosely referred to as WUI codes.

  • Climate change-related risks to 50% of U.S. military infrastructure: Pentagon

    Last Friday, the U.S. Department of Defense’s Office of the Under Secretary of Defense for Acquisition, Technology, and Logistics released a comprehensive new survey of climate change-related risks to military infrastructure worldwide. The vulnerability assessment does not offer any specific cost estimates related to these vulnerabilities, but it does paint a concerning picture of current climate change-related risks to military installations both at home and abroad, with around 50 percent of 1,684 sites reporting damage from six key categories of those risks: Flooding due to storm surge; flooding due to non-storm surge events (e.g., rain, snow, sleet, ice, river overflow); extreme temperatures (both hot and cold); wind; drought; and wildfire. Given that rapid climate change is projected to exacerbate most of the above categories of risks throughout this century (its effect on wind is less certain), the reasonable expectation is that vulnerabilities to military sites will only increase.

  • Some real “bombshell news” in the Mueller investigation

    Former Trump team legal spokesperson Mark Corallo, in the summer of 2016, had concerns that White House communications director Hope Hicks may be considering obstructing justice after a comment she made in a conference call about emails between Donald Trump Jr. and Russians with ties to the Kremlin. “Mark Corallo is a pro’s pro who went to work for the Trump legal team completely on board and who wanted to help the president … well, make America great again. When he left after two months with some reports that he was troubled by what he was seeing … that was a deeply ominous sign,” Jim Geraghty writes in National Review. “If Corallo ends up offering sort of critical testimony, this is not because he’s a Judas or because he’s part of the establishment or some sort of ‘Deep State’ sellout. It’s because he saw stuff that genuinely struck him as either illegal or unethical or both and he’s not the kind of person who’s willing to lie under oath about it.”

  • Netanyahu tells Putin Israel won’t allow Iranian bases in Syria, missile plants in Lebanon

    In talks with Russian President Vladimir Putin, Israeli Prime Minister Benjamin Netanyahu told Putin that Israel would not tolerate an Iranian military presence in Syria or making Lebanon into “factory for precision missiles” to attack Israel. Regarding Iranian efforts to establish a base of operations in Syria, Netanyahu said, “I made clear to Putin that we will stop it if it doesn’t stop by itself. We are already acting to stop it.”

  • New study examines the causes and consequences of the 2015 Texas floods

    The Memorial Day 2015 Wimberley, Texas flood along the Blanco River destroyed 350 homes and claimed 13 lives. The Texas Hill Country, where Wimberly is located, is known as “Flash Flood Alley” because it leads North America as the most flash-flood prone region. In the past five years, Flash Flood Alley has seen two “500-year storms” and one “300-year storm.” Researchers call for better storm preparations in light of this revelation, to allow for blocking roads and evacuation of residents.

  • California’s other drought: A major earthquake is overdue

    California earthquakes are a geologic inevitability. The earthquake situation in California is actually more dire than people who aren’t seismologists like myself may realize. The good news is that earthquake readiness is part of the state’s culture, and earthquake science is advancing – including much improved simulations of large quake effects and development of an early warning system for the Pacific coast. Early warning systems are operational now in Japan, Taiwan, Mexico and Romania. Systems in California and the Pacific Northwest are presently under development with early versions in operation. Earthquake early warning is by no means a panacea for saving lives and property, but it represents a significant step toward improving earthquake safety and awareness along the West Coast. Managing earthquake risk requires a resilient system of social awareness, education and communications, coupled with effective short- and long-term responses and implemented within an optimally safe built environment. As California prepares for large earthquakes after a hiatus of more than a century, the clock is ticking.

  • Hybrid warfare: Russia is “arch exponent” of the disappearing “distinct states of ‘peace’ and ‘war’”: U.K. military chief

    The West’s adversaries “have become masters at exploiting the seams between peace and war. What constitutes a weapon in this grey area no longer has to go ‘bang’. Energy, cash - as bribes - corrupt business practices, cyber-attacks, assassination, fake news, propaganda and indeed military intimidation are all examples of the weapons used to gain advantage in this era of ‘constant competition,’ and the rules-based international architecture that has assured our stability and prosperity since 1945 is, I suggest therefore, threatened,” Sir Nicholas Carter, the British Army chief of staff, said last week. “The deduction we should draw from this is that there is no longer two clear and distinct states of ‘peace’ and ‘war’; we now have several forms. Indeed the character of war and peace is different for each of the contexts in which these ‘weapon systems’ are applied,” he added. “The arch exponent of this [new approach to war] is Russia…. I believe it represents the most complex and capable state-based threat to our country since the end of the Cold War. And my fellow Chiefs of Staff from the United States, France, and Germany shared this view.”

  • Artificial intelligence is the weapon of the next Cold War

    As during the Cold War after the Second World War, nations are developing and building weapons based on advanced technology. During the Cold War, the weapon of choice was nuclear missiles; today it’s software, whether it is used for attacking computer systems or targets in the real world. Russian rhetoric about the importance of artificial intelligence is picking up – and with good reason: As artificial intelligence software develops, it will be able to make decisions based on more data, and more quickly, than humans can handle. As someone who researches the use of AI for applications as diverse as drones, self-driving vehicles and cybersecurity, I worry that the world may be entering – or perhaps already in – another cold war, fueled by AI. In a recent meeting at the Strategic Missile Academy near Moscow, Russian President Vladimir Putin suggested that AI may be the way Russia can rebalance the power shift created by the U.S. outspending Russia nearly 10-to-1 on defense each year. Russia’s state-sponsored RT media reported AI was “key to Russia beating [the] U.S. in defense.” With Russia embracing AI, other nations that don’t or those that restrict AI development risk becoming unable to compete – economically or militarily – with countries wielding developed AIs. Advanced AIs can create advantage for a nation’s businesses, not just its military, and those without AI may be severely disadvantaged. Perhaps most importantly, though, having sophisticated AIs in many countries could provide a deterrent against attacks, as happened with nuclear weapons during the Cold War.

  • Improving military communications with digital phased-arrays at millimeter wave

    There is increasing interest in making broader use of the millimeter wave frequency band for communications on small mobile platforms where narrow antenna beams from small radiating apertures provide enhanced communication security. Today’s millimeter wave systems, however, are not user friendly and are designed to be platform specific, lacking interoperability and are thus reserved for only the most complex platforms. New program aims to create multi-beam, digital phased-array technology, operating at 18-50 GHz to enhance secure communications between military platforms.

  • A custom-fit app for community policing

    Apps allowing citizens to report crimes or incidents are now commonplace, but they generally fail to adapt local contexts, cultures and sensibilities. SecureU, a new app that addresses this shortcoming, is currently being tested in five European cities.

  • Dutch intelligence instrumental in launching FBI’s investigation into U.S. election meddling

    In 2014, Dutch government hackers from AIVD, the Dutch intelligence agency, managed to infiltrate “the computer network of the infamous Russian hacker group Cozy Bear,” a Dutch newspaper reports. A year later, the Dutch operatives witnessed “Russian hackers launching an attack on the Democratic Party in the United States.” The penetration of the Russian network allowed the Dutch intelligence services to provide the FBI with valuable information. The Steele Dossier was taken so seriously by the FBI not only because Christopher Steele was a credible and reliable Russia expert – but because much of the raw intelligence contained in the dossier dovetailed with information the FBI already had from other sources – one of them being Dutch intelligence.

  • 2017 Critical Incident Exercise put first responder technologies to the test

    In the wee hours of 29 October 2017, more than 200 people participated in a critical incident exercise and technology assessment, conducted by DHS S&T and partner organizations. The exercise took place at the Grand Central Terminal in New York City, with most of the action occurring on parked trains and on track platforms, and other indoor spaces within the Terminal. Emergency medical technicians were dispatched to quickly convert ramps in front of several track platforms into triage stations. Outside, first responders set up an incident command post and an operations center to coordinate the simulated response.

  • Prosecuting background check, straw purchase violations depends on state laws

    A new study found that prosecutions in Pennsylvania for violating the state’s straw purchase law increased by nearly 16 times following the 2012 passage of a law requiring a mandatory minimum five-year sentence for individuals convicted of multiple straw purchase violations.  So-called straw purchases involve a prohibited person, such as someone with a criminal record, enlisting the aid of another person to buy the firearm on their behalf.

  • Texas smugglers say Trump's border wall wouldn't stop immigrants, drugs from pouring across the border

    If the Trump administration follows through on the president’s promises to build a border wall, would it actually stop undocumented immigrants and illegal drugs? Two former smugglers explain how they’d work around it.

  • Making production of high explosives cheaper, safer

    Scientists from the U.S. Army Research Laboratory (ARL) and the Lawrence Livermore National Laboratory found a solution to a significant challenge in making high-energy explosives. They safely improved the overall chemical yield derived from diaminoglyoxime, known as DAG, and significantly increased the amount of material made per reaction.
