• PlanetSense: Stepping in When Disaster Strikes

    As Hurricane Dorian raged through the Bahamas, researchers at Oak Ridge National Laboratory worked around the clock to aid recovery efforts for one of the Caribbean’s worst storms ever. The researchers helped direct that relief, churning out geographic data that guided decisions on everything from where to open emergency shelters to how to staff first-aid centers.

  • Biden Administration ‘Going after Violence’ in Crackdown on Domestic Terrorism

    By Jeff Seldin

    White House and Pentagon officials are defending decisions to conduct in-depth reviews of the dangers posed by domestic extremists in the United States, pushing back against criticism that the measures will result in a so-called political litmus test. Nascent anger over the new efforts to look at domestic extremism in the wake of the Jan. 6 siege of the U.S. Capitol building has been growing in recent days, touched off by a decision by Defense Secretary Lloyd Austin to order a military-wide stand-down to determine the scope of the problem.

  • New Timeline of Deadliest California Wildfire Could Guide Lifesaving Research, Action

    The November 2018 was the costliest disaster worldwide in 2018 and, having caused 85 deaths and destroyed more than 18,000 buildings, it became both the deadliest and most destructive wildfire in California’s history, two records the fire still holds today. What made the Camp Fire so devastating? And what lessons can we learn to prevent another disaster of this scale?

  • Swarming Drones Concept Flies Closer to Reality

    A swarm of twenty drones has recently completed the largest collaborative, military-focused evaluation of swarming uncrewed aerial vehicles (UAVs) in the U.K. The exercise was the culmination of the Defense Science and Technology Laboratory’s (DSTL) “Many Drones Make Light Work” competition

  • Robot Seeks Out Chemical Agents

    Scientists have successfully tested a fully autonomous robot that will help defense and security personnel dealing with hazardous scenes. The development of the robot means that humans and machines can now share the burden of detecting and report dangerous chemicals over large areas.

  • U.S. Police, Security Forces Brace for Trump Impeachment Trial

    By Jeff Seldin

    Security and police forces in and around Washington will be operating at what they describe as “a high-level of readiness” as the impeachment trial for former President Donald Trump gets underway next week, worried the event could serve as a flashpoint for American extremists still angry over the outcome of the presidential election. Officials have been hesitant to share specifics about the intelligence, some of which has been described as disturbing chatter on social media platforms.

  • Extremist-Related Shootouts with Police Soar in 2020

    During the 6 January 2021 attack on the U.S. Capitol, violent Trump supporters—reinforced by a broad coalition of right-wing extremists—attacked police, who appeared to be caught unprepared for a violent encounter with a crowd which has been loudly and consistently supportive of law enforcement. In 2020, there were 16 incidents in which police and extremists exchanged gunfire, an increase from the 11-year average of nine per year.

  • Tsunamis and Tsunami Warning: Recent Progress and Future Prospects

    Tsunamis are one of the most destructive disasters in the ocean. Large tsunamis are mostly generated by earthquakes, and they can propagate across the ocean without significantly losing energy. During the shoaling process in coastal areas, the wave amplitude increases dramatically, causing severe life loss and property damage. A recent paper reviews the recent research progress on earthquake-generated tsunamis, from the aspects of tsunami generation, propagation, inversion and warning.

  • Iran Enriched “17 Kilograms” of 20 Percent Enriched Uranium, Exceeding Nuclear Pact’s Limits

    Iran says it has produced 17 kilograms of 20 percent-enriched uranium within a month, as Iranian officials continue to dismiss international calls for Tehran to return to full compliance with the 2015 nuclear agreement. About 250 kilograms of 20 percent-enriched uranium are needed to convert it into 15-25 kilograms of the 90 percent-enriched needed for a Hiroshima-size nuclear weapon.

  • How Trump’s Focus on Antifa Distracted Attention from the Far-Right Threat

    In response to Donald Trump’s election-related insistence that the radical left endangered the country, federal law enforcement shifted resources last year from what experts agreed was a more ominous threat: the growing far-right extremism around the country. Trump’s efforts to focus his administration on the antifa movement and leftist groups did not stop the DOJ and the FBI from pursuing cases of right-wing extremism, but the effect of his direction was nonetheless substantial. The scale and intensity of the threat developing on the right became clear on 6 January.

  • Baltimore Aerial Investigations Associated with Small Improvements in Solving Crimes

    A preliminary report about an effort to use aerial surveillance to aid police investigations in Baltimore finds that the effort was associated with small increases in the rate at which police solved serious crimes, but an overall evaluation of the program will require a wider review of citywide police efforts, according to a new report.

  • The Shifting Burden of Wildfires in the United States

    Wildfire smoke will be one of the most widely felt health impacts of climate change throughout the country, but U.S. clean air regulations are not equipped to deal with it. Experts discuss the causes and impacts of wildfire activity and its rapid acceleration in the American west.

  • Four Ways the Biden Administration Can Revamp Disaster Management

    By Jeff Schlegelmilch

    In the United States, 2020 had more billion-dollar disasters than any other year in recorded history, even without accounting for the COVID-19pandemic. This is part of a growing trend of more powerful disasters, such as forest fires or hurricanes, across more susceptible areas. This vulnerability is becoming understood to include a combination of the built environment, governance, and underlying social vulnerability. Among federal agencies in the United States, disasters are managed by as many as 90 different programs across 20 agencies. These programs are an uneven patchwork, leaving significant gaps in some areas, and overlapping responsibilities and authorities in others.

  • Bold Action Can End Era of Pandemic Threats By 2030

    The Bipartisan Commission on Biodefense has called on the federal government to urgently implement the recommendations specified in its new report, The Apollo Program for Biodefense: Winning the Race Against Biological Threats. The report details an ambitious program to develop and deploy the technologies needed to defend against all biological threats, empower public health, and prevent pandemics.

  • Pandemic Shows Need for Biological Readiness

    By Andy Weber

    President Joe Biden’s inauguration comes during the worst stage of the deadliest biological event of our lifetimes. As bad as this pandemic is, imagine if instead it were caused by the deliberate release of a sophisticated biological weapon. About 2 percent of those infected have died of COVID-19, while a disease such as smallpox kills at a 30 percent rate. A bioengineered pathogen could be even more lethal. Our failed response to the pandemic in 2020 has exposed a gaping vulnerability to biological threats, ranging from natural outbreaks to deliberate biological weapons attacks.
