• Cities can save lives, resources by using a vulnerability reduction scorecard

    A new planning tool enables communities to effectively reduce their vulnerabilities to hazards across their network of plans – including transportation, parks, economic development, hazard mitigation, emergency management and comprehensive land use.

  • The costs of extreme weather

    An expert tells lawmakers that there is one “underappreciated” fact in discussions about the costs of climate change: “small shifts in long-term average conditions — what we call climate — can have a large effect on the frequency of extreme weather events.” Examples: “In 2017, Hurricane Harvey caused an estimated $125 billion in losses, with an estimated 200,000 homes experiencing damage. Ongoing flooding in the upper Midwest is sure to produce agricultural losses alone in the billions of dollars, and extreme drought across much of the U.S. in 2012 caused $33 billion in losses.”

  • Dutch aquifers bank rainwater to help farmers keep the water running

    Climate change is increasing the risk of water shortages across Europe, but researchers in the Netherlands are hoping to ease pressure by generating a steady supply of clean water and heat from deep underground reservoirs known as aquifers.

  • Wandering Earth: rocket scientist explains how we could move our planet

    In the Chinese science fiction film “The Wandering Earth,” recently released on Netflix, humanity attempts to change the Earth’s orbit using enormous thrusters in order to escape the expanding sun – and prevent a collision with Jupiter. The scenario may one day come true. How could we go about it and what are the engineering challenges?

  • Will the next cyberattack be in the hospital?

    You may not think of hackers targeting hospitals, but this is where our wired world may be most vulnerable, and the results could be deadly. Israeli startup Cynerio aims to stop hackers from targeting medical devices, a potent new danger in our connected world.

  • Locating a shooter from the first shot using cellphone

    In the past several decades, militaries have worked hard to develop technologies that simultaneously protect infantry soldiers’ hearing and aid in battlefield communication. Now a French researcher has developed a proof of concept that uses the microphones in a TCAPS system to capture a shooter’s acoustic information and transmit this to a soldier’s smartphone to display shooter location in real time.

  • The fundamental challenges of living with wildfire

    Wildfires can have dramatic impacts on Western landscapes and communities, but human values determine whether the changes caused by fire are desired or dreaded. This is the simple - but often overlooked - message from a collaborative team of researchers.

  • Floods will cost the U.K. billions, but AI can help make sewers the first defense

    The U.K. will need to spend £1 billion a year on flood management to avoid the worst consequences of climate change, according to the national Environment Agency. Coastal defenses – including sea walls, buffer areas and evacuation plans – can help to protect towns and cities against flooding from storm surges. But inland flooding caused by excess rainwater requires more nuanced solutions. Today, artificial intelligence (AI) can use data to help make decisions about how water should flow in and around human settlements, to avoid the worst effects of flooding.

  • As floods increase, cities like Detroit are looking to green stormwater infrastructure

    Urban sprawl meant paving over grasslands and wetlands, making it so water is unable to soak into the ground. Today, that impervious development, coupled with the more intense storms brought by climate change, is making flooding a major issue for many cities. Urban areas are looking for better ways to manage runoff.

  • Carbon dioxide levels in the atmosphere highest in human history

    Atmospheric levels of planet-warming carbon dioxide have hit a record high of more than 415 parts per million. Before the Industrial Revolution in the nineteenth century, carbon dioxide levels fluctuated but never exceeded 300 ppm at any one time over the past 800,000 years. Carbon dioxide levels in the atmosphere broke 400 ppm for the first time in human history in 2013.

  • Better earthquake protection for buildings

    Researchers examine how buildings with externally bonded fiber-reinforced polymer composite retrofits withstood the 30 November 2018 magnitude 7.1 earthquake in Alaska. By assessing how these buildings held up, the researchers hope to help engineers construct buildings that stand up to natural disasters.

  • As planet warms, even little precipitation may disrupt road networks

    A new computer model shows that as more rain falls on a warming planet, it may not take a downpour to cause widespread disruption of road networks. The model combined data on road networks with the hills and valleys of topography to reveal “tipping points” at which even small localized increases in rain cause widespread road outages.

  • Extreme floods associated with distinct atmospheric patterns

    Extreme floods across the continental United States are associated with four broad atmospheric patterns, a machine-learning based analysis of extreme floods found.

  • Maths shows the nature of “tipping points” for climate, eco crises

    Humans need to be wary of breaching a “point of no return” that leads to ecological disaster such as loss of rainforests or irreversible climate change, according to the most detailed study of its kind.

  • Finnish students outperform U.S. students on “fake news” digital literacy tasks

    A recent study revealed students at an international school in Finland significantly outperformed U.S. students on tasks which measure digital literacy in social media and online news. The researchers suggest this may be due to the Finnish and International Baccalaureate curricula’s different way of facilitating students’ critical thinking skills compared to the U.S. system and curriculum.
