Published New tagging method provides bioadhesive interface for marine sensors on diverse, soft, and fragile species
(via sciencedaily.com) Original source Tagging marine animals with sensors to track their movements and ocean conditions can provide important environmental and behavioral information. Existing techniques to attach sensors currently largely rely on invasive physical anchors, suction cups, and rigid glues. While these techniques can be effective for tracking marine animals with hard exoskeletons and large animals such as sharks, individuals can incur physiological and metabolic stress during the tagging process, which can affect the quality of data collection. A newly developed soft hydrogel-based bioadhesive interface for marine sensors, referred to as BIMS, holds promise as an effective, rapid, robust, and non-invasive method to tag and track all sorts of marine species, including soft and fragile species. The BIMS tagging, which is also simple and versatile, can help researchers better understand animal behavior while also capturing oceanographic data critical for helping to better understand some impacts of climate change and for resource management.

Published 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.
Published 'One ring to rule them all': How actin filaments are assembled by formins
(via sciencedaily.com) Original source Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing filament. Furthermore, the scientists elucidated the reasons for the different speeds at which the different formins promote this process.
Published 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.
Published How tardigrades can survive intense radiation
(via sciencedaily.com) Original source Researchers have discovered that tardigrades -- microscopic animals famed for surviving harsh extremes -- have an unusual response to radiation.
Published How blue-green algae manipulate microorganisms
(via sciencedaily.com) Original source A research team discovers previously unknown gene that indirectly promotes photosynthesis Protein regulator NirP1 influences the coordination of the nitrogen and carbohydrate metabolism 'Such protein regulators could in future be deployed in 'green' and 'blue' biotechnology for targeted control of the metabolism,' says geneticist.
