Since the creation of the National Flood Insurance Program (NFIP) in 1968, the U.S. government has paid over $51 billion to cover flood losses. Almost half of these payouts went to just 25 counties, among the fastest-growing counties by population. A new paper published in the Journal of the Association of Environmental and Resource Economists examines whether insuring people against potential flood losses contributes directly to population growth in flood-prone areas. In “Does the National Flood Insurance Program Drive Migration ...

Fresh research into the physics of vibrating nanobubbles reveals that they do not heat up as much as previously thought. Vibrating nanobubbles have surprising uses as ultrasound contrast agents in cancer diagnosis. They can also be forced to collapse - destroying nearby microscopic contaminants - for waste-water treatment and surface cleaning of delicate microfluidic devices. The stiffness of a nanobubble as it vibrates is strongly related to their internal temperature, and being able to understand ...

With over 2,780 fishing ports and 993 commercial and industrial ports, Japan faces the challenge of safeguarding these important coastal assets from the destructive forces of tsunamis. A promising solution lies in the form of a movable barrier system, where gates rising from the seafloor act as barriers, protecting ports against tsunamis, storm surges and high waves. However, during natural disasters, power outages may disrupt the electricity needed to operate the gate. To address this, researchers led by Professor Hiroshi Takagi from Tokyo Institute of Technology have proposed ...
