“#A histone modifier that facilitates an epigenetic switch” A depiction of the double helical structure of DNA. Its four coding units (A, T, C, G) are color-coded in pink, orange, purple and yellow. Credit: NHGRI Epigenetic regulation of gene expression is associated with switching between chromatin states characterized by distinct histone modifications. But how these…
“#Number of Australians facing housing stress doubles” Credit: Unsplash/CC0 Public Domain The number of Australians who couldn’t pay their rent or mortgage on time has more than doubled due to COVID-19, new data from The Australian National University (ANU) shows. The survey of more than 3,200 people shows the proportion of Australians not being able…
“#New study reveals attitudes towards climate migrants” Credit: Gerd Altmann, Pixabay A new study from an international team of researchers has looked at how residents in Vietnam and Kenya perceive those forced to migrate because of extreme climates. The research team, including Dr. Quynh Nguyen from The Australian National University (ANU) say climate-induced migration is…
“#Getting to the bottom of Antarctic ice shelf melt” Credit: Una Miller/Unsplash New measurements from the ocean under the center of the Ross Ice Shelf have significantly improved our understanding of the complex processes that drive melting in Antarctica. The measurements are the subject of a paper published this week in scientific journal Proceedings of…
“#No touching: Researchers find contactless way to measure thickness of carbon nanotube films” Preparing SWCNT fllms for the experiment. Credit: Pavel Odinev / Skoltech Scientists from Skoltech and their colleagues from Russia and Finland have figured out a non-invasive way to measure the thickness of single-walled carbon nanotube films, which may find applications in a…
“#Researchers propose generalized definition of cavitation intensity” The definition of cavitation intensity and its method of measurement. Credit: IACAS Cavitation usually refers to the generation and subsequent dynamic behaviors of cavities when liquid is exposed to a sufficient pressure drop. It has been widely used in sonochemistry, biomedicine, environmental science, and other areas. In recent…
“#Researchers directly obtain 3-D, full-color images with conventional microscope” Imaging of a compound eye at different depths of (a) 14 μm and (b) 28 μm acquired with FC-WFM method, OS with FC-SIM method, and the OS in DOF with proposed FC-WFM-Deep, respectively. Credit: XIOM Conventional wide-field microscopy (WFM) cannot provide optical sectioning (OS) images that…
“#What happens before a star explodes and dies: New research on ‘pre-supernova’ neutrinos.” Exploded star blooms like a cosmic flower. Credit: NASA/CXC/U.Texas A recent study on pre-supernova neutrinos—tiny cosmic particles that are extremely hard to detect—has brought scientists one step closer to understanding what happens to stars before they explode and die. The study, co-authored…
“#Beavers gnawing away at the Arctic permafrost” Credit: Pixabay/CC0 Public Domain Alaska’s beavers are profiting from climate change, and spreading rapidly. In just a few years’ time, they have not only expanded into many tundra regions where they’d never been seen before; they’re also building more and more dams in their new homes, creating a…
“#Ethnolinguistic diversity slows down urban growth” Credit: Pixabay/CC0 Public Domain Where various ethnic groups live together, cities grow at a slower rate. That is the conclusion reached by a researcher from the University of Basel and his colleagues based on worldwide data that shows how the diversity of language groups in 1975 has influenced urban…
