Airborne technology brings new hope to map shallow aquifers in Earth's most arid deserts      (via sciencedaily.com)     Original source 

The new technique will map the top of the aquifer, called the 'water table,' spanning areas as large as hundreds of kilometers using a radar mounted on a high-altitude aircraft. According to the researchers, Desert-SEA will measure the variabilities in the depth of the water table on a large scale, allowing water scientists to assess the sustainability of these aquifers without the limitations associated with in-situ mapping in harsh and inaccessible environments.

Breaking bonds to form bonds: Rethinking the Chemistry of Cations      (via sciencedaily.com)     Original source 

A team of chemists has achieved a significant breakthrough in the field of chemical synthesis, developing a novel method for manipulating carbon-hydrogen bonds. This groundbreaking discovery provides new insights into the molecular interactions of positively charged carbon atoms. By selectively targeting a specific C--H bond, they open doors to synthetic pathways that were previously closed -- with potential applications in medicine.

Spider silk sound system      (via sciencedaily.com)     Original source 

Researchers have investigated how spiders listen to their environments through webs and found that the webs match the acoustic particle velocity for a wide range of sound frequencies. Playing sound ranging from 1 Hz to 50 kHz for the spiders and measuring the spider silk motion with a laser vibrometer, they found the sound-induced velocity of the silk was the same as the particles in the air surrounding it. This confirmed the mechanism that these spiders use to detect their prey.

'Forever chemicals' found to rain down on all five Great Lakes      (via sciencedaily.com)     Original source 

Perfluoroalkyl and polyfluoroalkyl substances, also known as PFAS or 'forever chemicals,' have become persistent pollutants in the air, water and soil. Because they are so stable, they can be transported throughout the water cycle, making their way into drinking water sources and precipitation. Precipitation introduces similar amounts of PFAS into each of the Great Lakes; however, the lakes eliminate the chemicals at different rates.

Bioengineered enzyme creates natural vanillin from plants in one step      (via sciencedaily.com)     Original source 

Vanilla, the most widely used flavoring compound in confectionaries and cosmetics, gets its sweet flavor and aroma from the chemical compound -- 'vanillin'. However, the large-scale production of natural vanillin is impeded by the lack of microbial processes and enzymes which can commercially generate vanillin. Now, researchers have genetically engineered a novel enzyme which can convert ferulic acid from plant waste into vanillin in a one-step sustainable process.
