Candid cosmos: eROSITA cameras set benchmark for astronomical imaging

SPIE International Society for Optics and Photonics
Recently, the eROSITA (extended Roentgen Survey with an Imaging Telescope Array) x-ray telescope, an instrument developed by a team of scientists at Max-Planck-Institut für Extraterrestrische Physik (MPE), has gained attention among astronomers. The instrument performs an all-sky survey in the x-ray energy band of 0.2-8 kilo electron volts aboard the Spectrum-Roentgen-Gamma (SRG) satellite that was launched in 2019 from the Baikonur cosmodrome in Kazakhstan.
“The eROSITA has been designed to study the large-scale structure of the universe and test cosmological models, including dark energy, by detecting galaxy clusters with redshifts greater than 1, corresponding to a cosmological expansion faster than the speed of light,” said Dr. Norbert Meidinger from MPE, a part of the team that developed the instrument. “We expect eROSITA to revolutionize our understanding of the evolution of supermassive black holes.” The d ....

Researchers are first to create sterile male mosquitoes using CRISPER/Cas9

By Harrison Tasoff
Santa Barbara, CA
Mosquitoes are one of humanity’s greatest nemeses, estimated to spread infections to nearly 700 million people per year and cause more than one million deaths.
UC Santa Barbara Distinguished Professor Craig Montell has made a breakthrough in one technique for controlling populations of Aedes aegypti, a mosquito that transmits dengue, yellow fever, Zika and other viruses. The study, published in the Proceedings of the National Academy of Sciences, documents the first use of CRISPER/Cas9 gene editing to target a specific gene tied to fertility in male mosquitoes. The researchers were then able to discern how this mutation can suppress the fertility of female mosquitoes. ....

Darwin foreshadowed modern scientific theories

University of Tennessee at Knoxville
When Charles Darwin published Descent of Man 150 years ago, he launched scientific investigations on human origins and evolution. This week, three leading scientists in different, but related disciplines published “Modern theories of human evolution foreshadowed by Darwin’s Descent of Man,” in Science, in which they identify three insights from Darwin’s opus on human evolution that modern science has reinforced.
“Working together was a challenge because of disciplinary boundaries and different perspectives, but we succeeded,” said Sergey Gavrilets, lead author and professor in the Departments of Ecology and Evolutionary Biology and Mathematics at the University of Tennessee, Knoxville. ....

When One Becomes Three

Researchers from Tel Aviv University have discovered a species of ascidian, a marine animal commonly found in the Gulf of Eilat, is taking the concept of self-creation to a whole different level: it is capable of regenerating all of its organs fully – even if it is dissected into three fragments. The study was led by Prof. Noa Shenkar, Prof. Dorothee Huchon-Pupko, and Tal Gordon of Tel Aviv University’s School of Zoology at The George S. Wise Faculty of Life Sciences and The Steinhardt Museum of Natural History. The findings of this surprising discovery were published in the leading journal Frontiers in Cell and Developmental Biology. ....
