Atom-by-atom: Imaging structural transformations in 2D materials      (via sciencedaily.com)     Original source 

Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily difficult.

East coast mussel shells are becoming more porous in warming waters      (via sciencedaily.com)     Original source 

Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.

Florida Wildlife Corridor eases worst impacts of climate change      (via sciencedaily.com)     Original source 

Florida is projected to lose 3.5 million acres of land to development by 2070. A new study highlights how Florida can buffer itself against both climate change and population pressures by conserving the remaining 8 million acres of 'opportunity areas' within the Florida Wildlife Corridor (FLWC), the only designated statewide corridor in the U.S. Interactions between the FLWC and climate change had not been previously examined until now. Findings show substantial climate resilience benefits from the corridor, yielding a much higher return on investment than originally thought. About 90 percent of Floridians live within 20 miles of the corridor.

Photonic computation with sound waves      (via sciencedaily.com)     Original source 

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One challenge is the reconfigurability of optical neural networks. A research team has now succeeded in laying the foundation for new reconfigurable neuromorphic building blocks by adding a new dimension to photonic machine learning: sound waves. The researchers use light to create temporary acoustic waves in an optical fiber. The sound waves generated in this way can for instance enable a recurrent functionality in a telecom optical fiber, which is essential to interpreting contextual information such as language.

Hidden threat: Global underground infrastructure vulnerable to sea-level rise      (via sciencedaily.com)     Original source 

As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.
