Shoreline model predicts long-term future of storm protection and sea-level rise      (via sciencedaily.com)     Original source 

Researchers have created a coastal evolution model to analyze how coastal management activities on barrier islands, meant to adapt to sea-level rise, can disrupt natural processes that are keeping the barrier islands above water. Replenishing beaches and clearing over-washed roads may not be the best long term strategy.

High-resolution lidar sees birth zone of cloud droplets      (via sciencedaily.com)     Original source 

Scientists demonstrated the first-ever remote observations of the fine-scale structure at the base of clouds. The results show that the air-cloud interface is a transition zone where aerosol particles suspended in Earth's atmosphere give rise to the droplets that ultimately form clouds. The research will enable scientists to gain insight into how changes in atmospheric aerosol levels could affect clouds and climate.

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks      (via sciencedaily.com)     Original source 

A lead-vacancy (PbV) center in diamond has been developed as a quantum emitter for large-scale quantum networks by researchers. This innovative color center exhibits a sharp zero-phonon-line and emits photons with specific frequencies. The PbV color center stands out among other diamond color centers due to its ability to maintain optical properties at relatively high temperatures of 16 K. This makes it well-suited for transferring quantum information in large-scale quantum networks.

Frog species evolved rapidly in response to road salts      (via sciencedaily.com)     Original source 

When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a species of frog that has evolved over the course of merely 25 years. The adaptation was spurred on by something many assume is innocuous: salt.

Asian monsoon lofts ozone-depleting substances to stratosphere      (via sciencedaily.com)     Original source 

Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research. The study found that the East Asian Monsoon delivers more than twice the concentration of very short-lived ozone-depleting substances into the upper troposphere and lower stratosphere than previously reported.

Warming climate is putting more metals into Colorado's mountain streams      (via sciencedaily.com)     Original source 

Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once sealed away by ice as the likely causes.

Marginalized communities developed 'disaster subculture' when living through extreme climate events      (via sciencedaily.com)     Original source 

An assistant professor conducted a study in which he lived among one of the poorest, most marginalized communities in Seoul, South Korea. In the ethnographic study, he asked residents how they dealt with extreme heat. He found they tended to accept the conditions, stating there was not much that could be done. That shows people accepted extreme climate events, despite evidence showing this should not be normal, which bodes the argument social work as a field has much to do to help address climate emergencies.

'Sunny day flooding' increases fecal contamination of coastal waters      (via sciencedaily.com)     Original source 

A new study finds that 'sunny day flooding,' which occurs during high tides, increases the levels of fecal bacteria in coastal waters. While the elevated bacteria levels in the coastal waters tend to dissipate quickly, the findings suggest policymakers and public health officials should be aware of potential risks associated with tidal flooding.

Laser-treated cork absorbs oil for carbon-neutral ocean cleanup      (via sciencedaily.com)     Original source 

Researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material's light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling. The laser treatments not only help to better absorb oil, but also work to keep water out.

Perfecting the view on a crystal's imperfection      (via sciencedaily.com)     Original source 

Hexagonal boron nitride (hBN) has gained widespread attention and application across various quantum fields and technologies because it contains single-photon emmiters (SPEs), along with a layered structure that is easy to manipulation. The precise mechanisms governing the development and function of SPEs within hBN have remained elusive. Now, a new study reveals significant insights into the properties of hBN, offering a solution to discrepancies in previous research on the proposed origins of SPEs within the material.

World's oases threatened by desertification, even as humans expand them      (via sciencedaily.com)     Original source 

Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile existence. New research shows how the world's oases have grown and shrunk over the past 25 years as water availability patterns changed and desertification encroaches on these wet refuges.

Invasive species sound off about impending ecosystem changes      (via sciencedaily.com)     Original source 

Anticipating changes to ecosystems is often at best an educated guess, but what if there was a way to better tune into possible changes occurring? Researchers have discovered that the silent growth of non-native invasive plants can affect the soundscape of an ecosystem. These altered soundscapes, the acoustic patterns of a landscape through space and time, may provide a key to better observing the hard-to-see physical and biological changes occurring in an ecosystem as they are beginning.
