• How Much Damage Could a Russian Cyberattack Do in the U.S.?

    By Scott Jasper

    U.S. intelligence analysts have determined that Moscow would consider a cyberattack against the U.S. as the Ukraine crisis grows. As a scholar of Russian cyber operations, I know the Kremlin has the capacity to damage critical U.S. infrastructure systems.

  • Wide Range of Possible Targets for Russian Cyberstrikes, from Infrastructure to Smartphones

    By Colleen Walsh

    For years prior to Russia’s invasion of Ukraine, Vladimir Putin’s government waged cyberwar aimed at destabilizing the country’s infrastructure, government, and financial systems, including several distributed-denial-of-service (DDoS) attacks in the run-up to this week’s assault. What are Russia’s cyberwarfare capabilities, and what would a cyberattack against the U.S. look like?

  • The U.S. Digital Security Challenges: Q&A with Frederic Lemieux

    The U.S. is facing many digital challenges: Ransomware attacks; critical infrastructure vulnerability; exploitation of flaws in widely used software packages such as SolarWinds; potential Russian cyberattacks resulting from the Ukraine crisis; shortage of cybersecurity talent which leaves many government and private sector positions vacant; and many more. HSNW talked with Georgetown’s Professor Frederic Lemieux, a recognized expert in the fields of global threats and homeland security.

  • Lake Evaporation Patterns Will Shift with Climate Change

    Lakes serve as a major global source of freshwater. As temperatures continue to get warmer, so will lakes. As global average temperatures rise, lake evaporation is projected to increase at double the rate of ocean evaporation. However, future increases in lake evaporation vary substantially across regions.

  • What Drives Sea Level Rise? U.S. Report Warns of 1-Foot Rise within Three Decades and More Frequent Flooding

    By Jianjun Yin

    Sea levels are rising, and that will bring profound flood risks to large parts of the Gulf and Atlantic coasts over the next three decades. A new report led by scientists at the National Oceanic and Atmospheric Administration warns that the U.S. should prepare for 10-12 inches of relative sea level rise on average in the next 30 years. That much sea level rise means cities like Miami that see nuisance flooding during high tides today will experience more damaging floods by midcentury.

  • U.S. Coastline to See Up to a Foot of Sea Level Rise by 2050

    The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That’s according to a NOAA-led report updating sea level rise decision-support information for the U.S. The report also finds that the sea level rise expected by 2050 will create a profound increase in the frequency of coastal flooding, even in the absence of storms or heavy rainfall.

  • Identifying “Double-Hazard” Zones for Wildfire in the West

    Rapidly growing communities in the American West’s forests and shrublands are nestled in zones where local soil and plant traits amplify the effect of climate change on wildfire hazards and lead to bigger burns.

  • NSA Releases 2021 Cybersecurity Year in Review

    The NSA last week released its 2021 NSA Cybersecurity Year in Review which highlights how the agency continues to address threats to the U.S. most critical systems.

  • Cyberattacks on Belgian Energy Companies

    Oil facilities at Belgian ports have been hit with a cyberattack. The news comes a day after Germany launched an investigation into a similar incident.

  • When Water Is Coming from All Sides

    When hurricanes hit, it is not solely the storm surge from the Gulf of Mexico and Atlantic Ocean that led to flooding. Inland sources, like rain-swollen rivers, lakes and suburban culverts, also contributed significantly. Researchers have developed and tested the world’s first 3D operational storm surge model, which takes these factors, which were missed by many computer models at the time, into account.

  • Losing a Hectare of Wetlands Could Cost $8,000 Per Year in Flood Damages

    A new study finds that the loss of a hectare of wetlands — an area of land roughly the size of two football fields — costs society an average of $1,900 in flood damages per year. In developed areas, that figure jumps to more than $8,000.

  • Germany needs to invest in nature to defend against floods

    By Jane Madgwick

    Wednesday, 2 February, is the first international World Wetlands Day. It should prompt action to restore these vital ecosystems to protect communities, biodiversity, and prevent future disasters

  • Functionally Graded Material Resistant to Blasts, Fire in buildings

    When a bomb goes off or fire breaks out, a building constructed or retrofitted with an engineered composite currently confined to special applications could buy the surviving occupants extra time to get out. Functionally graded material (FGM), a recently developed composite characterized by the gradual variation of material properties across its thickness, is an effective bomb-resistant material in structural uses.

  • Assessing Bridge Support Repairs After Earthquakes

    Steel-reinforced concrete columns that support many of the world’s bridges are designed to withstand earthquakes, but always require inspection and often repair once the shaking is over. Engineers simulate restoration strategies for reinforced concrete columns.

  • $3.5 Million NSF Grant to Fund Cybersecurity Scholarships

    A $3.5 million grant will fund new scholarships at Binghamton University over the next five years for two dozen students who plan to join the workforce as cybersecurity professionals. The NSF’s CyberCorps Scholarship for Service program trains the next generation of information technology experts and security managers.
