In the early-morning hours of today, 14 October 2022, astronomers using the Gemini South telescope in Chile operated by NSF's NOIRLab observed the unprecedented aftermath of one of the most powerful explosions ever recorded, Gamma-Ray Burst GRB221009A. This record-shattering event, which was first detected on 9 October 2022 by orbiting X-ray and gamma-ray telescopes, occurred 2.4 billion light-years from Earth and was likely triggered by a supernova explosion giving birth to a black hole.
A new study from North Carolina State University shows a reproducible way of studying cellular communication among varied types of plant cells by "bioprinting" these cells via a 3D printer. Learning more about how plant cells communicate with each other—and with their environment—is key to understanding more about plant cell functions and could ultimately lead to creating better crop varieties and optimal growing environments.
Bacterial infectious diseases are still a huge contributor to global disease burden and with antibiotic resistance on the rise worldwide there is an urgent need for novel treatment strategies against bacteria. One of the most devastating bacterial infections is Cholera, caused by the bacteria Vibrio cholerae, which has been in its seventh ongoing pandemic since 1961. Now, a research group led by Osaka University in Japan has shed light on a specific protein interaction that has the potential to be a novel target in Cholera treatment.
Oxygen levels in the Earth's atmosphere are likely to have "fluctuated wildly" 1 billion years ago, creating conditions that could have accelerated the development of early animal life, according to new research.
Scientists from the Faculty of Physics at the University of Warsaw in cooperation with the Military University of Technology, the Italian CNR Nanotec, the British University of Southampton and the University of Iceland obtained a new photonic system with electrically tuned topological features, constructed of perovskites and liquid crystals. Their research is published in the latest Science Advances.
