“#Green glowing worms provide live-action movies of the body’s internal scaffolding” Protein molecules move within a stable scaffolding in the sheet-like mesh that surrounds and supports most animal tissues. Credit: A. Kawska Duke University researchers have made the first time-lapse movies of the sheet-like latticework that surrounds and supports most animal tissues. A thin layer…
“#New method estimates risks of hormone-disrupting substances in drinking water” Credit: Pixabay/CC0 Public Domain Researchers at Karolinska Institutet have developed a new method that can make it easier for public authorities to assess the health risks of hormone-disrupting chemicals in the environment. The method was used to evaluate the risk associated with exposure data from…
“#Study determines fundamental parameters of the chemically peculiar star HD 108662” Element abundances in the atmosphere of HD 108662. Credit: Romanovskaya et al., 2020. Astronomers have carried out a spectroscopic analysis of the atmosphere of a magnetic chemically peculiar star designated HD 108662. The study, described in a paper published June 29 on the arXiv…
“#Excessive risky credit strongly linked to last decade’s housing crisis, study says” Credit: Pixabay/CC0 Public Domain In examining one of the biggest unresolved questions surrounding the 2008 financial crisis, a new study from the McCombs School of Business at The University of Texas at Austin raises red flags on risky credit practices that may have…
“#Plate tectonics research rewrites history of Earth’s continents” Credit: Pixabay Curtin University-led research has found new evidence to suggest that the Earth’s first continents were not formed by subduction in a modern-like plate tectonics environment as previously thought, and instead may have been created by an entirely different process. Published in the journal Geology, the…
“#Most lakes continuously release nitrogen into the atmosphere” Lake Itasca in Clearwater County, Minnesota. Credit: Jim Cotner In a process that may help lakes maintain healthy levels of nutrients, new research from the University of Minnesota College of Biological Sciences shows that a majority of the lakes examined are continuously shedding nitrogen into the atmosphere….
“#Tackling coral reefs’ thorny problem” The crown-of-thorns starfish is a predator of coral. Credit: Okinawa Institute of Science and Technology Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have revealed the evolutionary history of the crown-of-thorns starfish—a predator of coral that can devastate coral reefs. Their findings shed light on how…
“#New biomaterial could shield against harmful radiation” Human cells treated with selenomelanin nanoparticles. Credit: Northwestern University Packing for outer space? Here’s one thing you won’t want to forget. Northwestern University researchers have synthesized a new form of melanin enriched with selenium. Called selenomelanin, this new biomaterial shows extraordinary promise as a shield for human tissue…
