An international team of astronomers reports a serendipitous discovery of a new radio ring toward the Galactic center. The newfound object is relatively faint and its true nature is yet unknown. The finding was reported in a research paper forthcoming in the Astronomy & Astrophysics journal. An international team of astronomers reports a serendipitous discovery of…
The hottest warm period in the past million years is believed to have occurred about 400,000 years ago. During this time, the Northern Hemisphere had less ice than today, and sea levels were about 10 meters higher. Surprisingly, solar radiation, a key driver of warm periods, was weak during this time, and greenhouse gas levels…
An international team of geneticists and molecular biologists has discovered the first-known, free-living eukaryote to have lost its mitochondria. In their study, published in Nature Communications, the group found the eukaryote while investigating the patterns and processes of genome and mitochondrion-related organelles’ evolution in metamonads in water samples collected from saltwater lakes and shallow marine…
Theropod dinosaurs are one of the most important large groups of dinosaurs, including well-known predators, such as Tyrannosaurus and Allosaurus, as well as modern birds. A variety of theropods are known from the Mesozoic Era, the age of the dinosaurs. Theropod dinosaurs are one of the most important large groups of dinosaurs, including well-known predators, such…
New research reveals that triggering a cell’s DNA damage response could be a promising avenue for developing novel treatments against several rare but devastating viruses for which no antiviral treatments exist, possibly including human papilloma virus (HPV), which causes cancer. New research reveals that triggering a cell’s DNA damage response could be a promising avenue for…
An extensive family of proteins that gives human skin mechanical strength also appears to organize molecular signals that control skin cell activity, a study led by UT Southwestern Medical Center researchers shows. The team’s findings, published in Developmental Cell, could lead to new ways to fight a host of skin diseases, including ulcers and skin…
Solution-processed semiconductor nanocrystals are also called colloidal quantum dots (QDs). While the concept of size-dependent quantum effects had long been known to physicists, a sculpture of the theory into real nanodimensional objects remained impossible till the discovery of QDs. The size-dependent colors of QDs are essentially naked-eye, ambient-condition visualizations of the quantum size effect. Solution-processed semiconductor…
