• Hypersonic WeaponsHypersonic Missiles Are Fueling Fears of a New Superpower Arms Race

    By Christoph Bluth

    Hypersonic missiles are often defined as missiles launched by a rocket into Earth’s upper atmosphere at speeds of Mach 5 and above (five times the speed of sound or 6,174 kilometers (3,836 miles) per hour), before maneuvering towards a target. Several countries already have intercontinental ballistic missiles (ICBMs) that travel just as fast – or even faster – but these cannot change trajectory once launched. The new generation of hypersonic missiles are equipped with glide vehicles that approach their targets at high speed in the final phase of flight.

  • PandemicsTwo-meter COVID-19 Rule Is “Arbitrary Measurement” of Safety

    A new study has shown that the airborne transmission of COVID-19 is highly random and suggests that the two-meter rule was a number chosen from a risk ‘continuum’, rather than any concrete measurement of safety.

  • CybersecurityStacked Deep Learning: Deeper Defense against Cyberattacks

    Internet-based industrial control systems are widely used to monitor and operate factories and critical infrastructure. Moving these systems online has made them cheaper and easier to access, but it has also made them more vulnerable to attack. Stacked deep learning offers a better way to detect hacking into industrial control systems. 

  • EarthquakesMachine Learning Helps Measure Building Earthquake Damage

    One obstacle which often prevent an effective response to earthquakes is that the buildings from which such a response is managed and response equipment stored, are themselves damaged. Researchers have developed a method to quickly assess damage to such buildings immediately after an earthquake to determine whether the buildings can be continued to be used.

  • Energy SecurityBig Batteries on Wheels: Zero-Emissions Rail While Securing the Grid

    Trains have been on the sidelines of electrification efforts for a long time in the U.S. because they account for only 2 percent of transportation sector emissions, but diesel freight trains emit 35 million metric tons of carbon dioxide annually and produce air pollution that leads to $6.5 billion in health costs, resulting in an estimated 1,000 premature deaths each year. Researchers show how battery-electric trains can deliver environmental benefits, cost-savings, and resilience to the U.S.

  • Climate & National SecurityNational Security Consequences of Climate Change

    The consequences of climate change for national security and international stability are numerus and serious. Rising temperatures which reduce agricultural opportunities can lead to mass migrations away from struggling communities. Violent hurricanes and winter storms can disrupt electric grid operations, interrupting access to electricity and other utilities long after the initial climate threat has passed. Researchers are simulating how climate change affects the safety and security of the country.

  • Climate & National SecurityHow Climate Change Will Impact National Security

    By Christina Pazzanese

    The recent U.S. National Intelligence Estimate (NIE) lays out the likely security implications over the next two decades of the mounting climate crisis. Calder Walton, the research director at Harvard’s Belfer Center, says: “Let’s start with the basics: that climate change does pose a threat to U.S. national security. The National Intelligence Estimate is a joint assessment produced by the entire U.S. intelligence community, 18 agencies. That’s significant. There are no naysayers; there’s no doubt. So that’s a breakthrough. In this extraordinarily polarized and politicized environment, that is a big milestone itself.”

  • Planetary SecurityFirst Planetary Defense Test

    An asteroid slammed into Earth 63 billion years ago, igniting vast fires which threw smoke and soot into the atmosphere, plunging the planet into a prolonged winter, killing many plants on which herbivores depended. The extinction of the dinosaurs was only one consequence of that event. NASA wants to make sure there is no repetition of such a calamity: The agency is planning the first-ever planetary defense test, which deliberately collides a spacecraft into an asteroid called Dimorphos. The aim is to try and deflect the asteroid away from its Earth-bound trajectory.

  • Iran’s NukesIran Can Produce One Nuclear Weapon in as Little as Three Weeks

    The growth of Iran’s stocks of near 20 and 60 percent enriched uranium has dangerously reduced breakout timelines: Iran has enough enriched uranium hexafluoride (UF6) in the form of near 20 and 60 percent enriched uranium to produce enough weapon-grade uranium (WGU), taken here as 25 kilograms (kg), for a single nuclear weapon in as little as three weeks. It could do so without using any of its stock of uranium enriched up to 5 percent as feedstock.

The study finds that forcibly separating parents and children, especially when compounded with pre-migration traumas, produced signs and symptoms of trauma that met the diagnostic criteria for at least one mental health condition such as post-traumatic stress disorder (PTSD), major depressive disorder (MDD), or generalized anxiety disorder (GAD).

    By Jamie Dettmer

    For more than a year, Russian-aligned troll factories overseeing thousands of social media accounts have been spreading anti-vaccine messages in an aggressive campaign to spread conspiracy theories and cast doubt on Western coronavirus vaccines. But the year-long offensive appears to have backfired. Russian officials now worry that the anti-vaccine skepticism encouraged by the troll factories has spilled over and is partly responsible for the high level of vaccine hesitancy among Russians.
