Ariane 6 undergoing preparations for its 2022 debut
Lead image: Rendering of Ariane 64 on the launchpad – via ESA ArianeGroup and the European Space Agency are carrying out preparations for the maiden launch of the Ariane 6 rocket next year. Ariane 6 represents the next generation of the Ariane family of rockets, intended to allow its customers lower-cost access to space. The rocket and launch pad still have an extensive test program ahead of them, with a current target launch date in the second half of 2022. Ariane 6 is the sixth member of the Ariane family of rockets, whose development began in the 1970s to allow…

Are We Alone in the Universe? NASA Calls for New Scientific Framework in Search for Extraterrestrial Life
This artist’s concept allows us to imagine what it would be like to stand on the surface of the exoplanet TRAPPIST-1f, located in the TRAPPIST-1 system in the constellation Aquarius. Credit: NASA/JPL-Caltech How do we understand the significance of new scientific results related to the search for life? When would we be able to say, “yes, extraterrestrial life has been found?” NASA scientists are encouraging the scientific community to establish a new framework that provides context for findings related to the search for life. Writing in the journal Nature, they propose creating a scale for evaluating and combining different lines…

Early Dinosaurs Were Social and Lived in Herds – May Have Been Key to Their Success
Lead Image: Artistic reconstruction of a Mussaurus patagonicus nest. Credit: Jorge Gonzalez New research on a vast fossil site in Patagonia shows that some of the earliest dinosaurs lived in herds and suggests that this behavior may have been one of the keys to the success of dinosaurs. The discovery, at the ESRF, of embryos of the same species inside fossilized eggs contributed to the results. In the past, studies have shown that some dinosaurs that existed in the latest stage of the dinosaur Era (the Cretaceous Period) lived in herds. However, a major pending question was when and how…

RNA Control Switch: Engineers Devise a Way To Selectively Turn On Gene Therapies in Human Cells
A new RNA-based control switch could be used to trigger production of therapeutic proteins to treat cancer or other diseases. Researchers at MIT and Harvard University have designed a way to selectively turn on gene therapies in target cells, including human cells. Their technology can detect specific messenger RNA sequences in cells, and that detection then triggers production of a specific protein from a transgene, or artificial gene. Because transgenes can have negative and even dangerous effects when expressed in the wrong cells, the researchers wanted to find a way to reduce off-target effects from gene therapies. One way of…

Mysterious Physics Still Unexplained: MicroBooNE Experiment Shows No Hint of Sterile Neutrino
New results from the MicroBooNE experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory deal a blow to a theoretical particle known as the sterile neutrino. For more than two decades, this proposed fourth neutrino has remained a promising explanation for anomalies seen in earlier physics experiments. Finding a new particle would be a major discovery and a radical shift in our understanding of the universe. However, four complementary analyses released by the international MicroBooNE collaboration and presented during a seminar today all show the same thing: no sign of the sterile neutrino. Instead, the results align with…
