Coal-based product could replace sand in concrete      (via sciencedaily.com)     Original source 

A new study found that graphene derived from metallurgical coke, a coal-based product, through flash Joule heating could serve not only as a reinforcing additive in cement but also as a replacement for sand in concrete.

Permeable pavements could reduce coho-killing tire pollutants      (via sciencedaily.com)     Original source 

The pore-like structure of permeable pavements may help protect coho salmon by preventing tire wear particles and related contaminants from entering stormwater runoff, according to a recent study. Researchers demonstrated that four types of permeable pavements can act as giant filters, retaining more than 96% of applied tire particle mass. They also captured several tire-associated chemicals, resulting in a 68% average reduction of 6PPD-quinone, a contaminant shown to kill coho salmon in urban streams.

2020 US rule dramatically deregulated wetlands, streams and drinking water      (via sciencedaily.com)     Original source 

New research used machine learning to more accurately predict which waterways are protected by the Clean Water Act. The analysis found that a 2020 Trump administration rule removed Clean Water Act protection for one-fourth of US wetlands and one-fifth of US streams, and also deregulated 30% of watersheds that supply drinking water to household taps.

Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness      (via sciencedaily.com)     Original source 

How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.

Self-powered movable seawall for tsunami protection and emergency power generation      (via sciencedaily.com)     Original source 

A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.

Global warming has a bigger effect on compact, fast-moving typhoons      (via sciencedaily.com)     Original source 

A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.

New tool predicts flood risk from hurricanes in a warming climate      (via sciencedaily.com)     Original source 

A new method predicts how much flooding a coastal community is likely to experience as hurricanes evolve due to climate change. Using New York as a test case, the model predicts Hurricane Sandy-level flooding will occur roughly every 30 years by 2099.

Global groundwater depletion is accelerating, but is not inevitable      (via sciencedaily.com)     Original source 

Groundwater is rapidly declining across the globe, often at accelerating rates. Researchers now present the largest assessment of groundwater levels around the world, spanning nearly 1,700 aquifers. In addition to raising the alarm over declining water resources, the work offers instructive examples of where things are going well, and how groundwater depletion can be solved. The study is a boon for scientists, policy makers and resource managers working to understand global groundwater dynamics.

Discovering the physics behind 300-year-old firefighting methods      (via sciencedaily.com)     Original source 

Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber's Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.

Wobbling particles in the sky      (via sciencedaily.com)     Original source 

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size smaller than 1 millimeter with unprecedented accuracy. Their observations gave rise to a model which can help to refine prediction on air pollutants or weather forecasts.
