• Is There a Link Between Mental Health and Mass Shootings?

    There have already been more than 300 mass shootings in the United States this year—the latest at a 4th of July parade in the Highland Park suburb of Chicago. That shooting left seven dead, including both parents of a 2-year old toddler, and dozens injured – among them an 8-year old with a severed spinal cord, leaving him paralyzed from the waist down for the rest of his life. As the United States reckons with these increasingly common public massacres, many blame mental illness as the fundamental cause. The reality, however, is that people with mental illness account for a very small proportion of perpetrators of mass shootings in the United States, says one expert.

  • To Reach the Public, Highlight the Health Implications of Climate Change: Expert

    Among the health effects of climate change: Increases in extreme heat can lead to more heat-related illness and death from heat stroke and dehydration. Poor air quality can cause more lung infections, asthma and allergy attacks, bronchitis, and deaths. Rising temperatures can also increase the geographic range of disease-carrying insects and animals, resulting in faster and wider spread of diseases like Zika virus. Rising temperatures and extreme weather conditions make it easier for food and water to become contaminated by bacteria, viruses, parasites, and other toxins.

    Looking for potential “black swan” outbreaks can help us prepare for the future.

  • Would Russia Use Bioweapons in Ukraine?

    In March, claims from the Kremlin of a U.S.-funded bioweapon program in Ukraine flooded global media. Those reports were amplified by China and picked up by conservative news outlets and conspiracy groups in the U.S. U.S. warned that Russia could be using this thread of disinformation to stage a false-flag incident using bioweapons, or to justify the use of its own bioweapons against Ukraine. It wouldn’t have been the first time Russia used false-flag tactics, and the threat of Russia using bioweapons in either scenario isn’t an outlandish prospect.

  • Radioactive Sources: Discussing Safety and Security

    Today, radioactive sources are used in many areas including energy, medicine, industry, food and agriculture, research, and in environmental monitoring and protection. “Radioactive sources are all around us, offering immense societal and economic benefits, but they may also pose a risk. Managing these sources well, protects us from accidental radiation exposure and keeps them away from people with malicious intent,” said IAEA Director General Rafael Mariano Grossi.

  • Most Major U.S. Cities Underprepared for Rising Temperatures

    This month, Denver, Las Vegas and Phoenix all posted record high temperatures. And across the nation, Americans are ramping up for a scorching summer. Yet despite more frequent and intense heat waves on the horizon, cities are underprepared to deal with the challenge.

  • Assessing the Risks of Toxic or Flammable Clouds

    The Chemical Security Analysis Center was established by the Department of Homeland Security to identify and assess chemical threats and vulnerabilities in the United States and develop the best responses to potential chemical hazards.

  • The Risk of Drinking Contaminated Water During Flooding

    In addition to causing property damage and psychological impacts, flooding can pose a significant health risk, particularly due to contamination of drinking water sources. Researchers are a decision-making tool to estimate the risk of water contamination in flooded areas.

  • The Pandemic: Implications for Terrorist Interest in Biological Weapons

    What if the IS or al-Qaeda obtained and spread a highly contagious virus in a community or country that they sought to punish? With the pandemic highlighting weaknesses in response efforts, will these groups now seek to obtain infectious viruses to achieve these same deadly results?

  • Groundwater Depletion Causes California Farmland to Sink

    A new study simulates 65 years of land subsidence, or sinking, caused by groundwater depletion in California’s San Joaquin Valley. The results suggest significant sinking may continue for centuries after water levels stop declining but could slow within a few years if aquifers recover.

  • Keeping Communities Safe from Chemical Hazards During Hurricane

    Extreme weather from hurricanes and tropical storms can devastate communities along the Atlantic, Gulf and Pacific coasts, and the threat of subsequent hazard chemical releases can be just as deadly.

  • China’s Growing Agricultural Problems Pose Risks for the U.S.

    China is facing a growing demand on its agricultural production. The Chinese government has taken several domestic initiatives to address the growing problem, but it has also gone abroad to address its needs through investments and acquisitions of farmland, animal husbandry, agricultural equipment, and intellectual property (IP), particularly of GM seeds These efforts present several risks to U.S. economic and national security.

  • Food Production Vulnerable to Cyberattacks

    Wide-ranging use of smart technologies is raising global agricultural production but cyber experts warn this digital-age phenomenon could reap a crop of another kind – cybersecurity attacks.

  • Reforming DHS’s Biodefense Operations and Governance

    Today’s biological threats show no signs of desisting any time soon. Naturally occurring outbreaks, epidemics and pandemics, and laboratory accidents pose a growing challenge – while the number of high-containment laboratories and amount of dangerous research continues to increase unabated. “DHS, as chief among those federal departments and agencies responsible for securing the homeland, must overcome its current state of fractionation and demonstrate to the rest of the government, country, and world that it is capable of coordinating and leading efforts in biodefense and other arenas,” Carrie Cordero and Asha M. George write.

  • Nearly 108,000 Overdose Deaths in 2021 Bear Out a Prediction from Five Years Ago

    A grim prediction made half a decade ago by University of Pittsburgh School of Public Health epidemiologists and modelers has come true: More than 100,000 people are now dying from drug overdoses annually in the U.S.
