When you think about DNA, the first thing that probably comes to mind is the double helix model published by Watson and Crick. However, in the 90s scientists identified a particular conformation in DNA molecules in vitro (in a tube): single chain knot-like loops that they called i-motifs. These structures form because, instead of the […]
Fast radio bursts linked to massive galaxies Scientists have discovered that fast radio bursts, or FRBs, are more likely to originate in massive, metal-rich galaxies, suggesting that these cosmic phenomena may be linked to the formation of magnetars through stellar mergers. The study in Nature used the Deep Synoptic Array-110 to analyze the origins of […]
The term FGK star designates a star the spectrum of which makes it either an F-type star (yellow-white, a bit hotter than then Sun ), a G-type star (yellow, similar to the Sun), or a K-type star (orange, a bit cooler than the Sun). FGK stars come in a variety of sizes but segregating them […]
Authors: Sven Vanneste, Professor of Clinical Neuroscience, Trinity College Dublin and Elva Arulchelvan, Lecturer in Psychology and PhD Researcher in Psychology and Neuroscience, Trinity College Dublin Forgetting is part of our daily lives. You may walk into a room only to forget why you went in there – or perhaps someone says hi on the […]
Supermassive black holes exist at the centre of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the universe’s evolution. It’s difficult to understand how these black holes were able to grow so big so rapidly. But with the discovery of a low-mass supermassive black hole feasting on material at […]
The idea of the countless “virtual worlds” that the metaverse will contain is, as we saw in our last entry, an extrapolation of the idea of “video game worlds,” not necessarily regarding their playful nature—since the metaverse is expected to be a place for almost any kind of activity, not just leisure—but in the sense […]
Black holes may contribute to universe’s expansion Astronomers proposed a link between black holes and dark energy, potentially explaining the universe’s expansion, according to a study in the Journal of Cosmology and Astroparticle Physics, though researchers said that further observations are needed to confirm the connection. “The two phenomena were consistent with each other — […]
A new review article stresses out the necessity of the integration of new generation post-quantum cryptography protocols to industrial and critical infrastructures environments. The exponential development of communication technologies in the late 20th century and, specially, in the early 21 st century has resulted in a contemporary society that exists in a hyperconnected world. In […]
Author: Richard Massey, Professor of extragalactic astrophysics (dark matter and cosmology), Durham University In recent decades, we’ve learnt huge amounts about the universe and its history. The rapidly developing technology of telescopes – both on Earth and in space – has been a key part of this process, and those that are due to start […]
A new study by Professor Ella Been from Ono Academic College and Dr. Omry Barzilai from the University of Haifa sheds new light on the burial practices of Homo sapiens and Neanderthals in the Levant region during the Middle Paleolithic (MP). The research, which examined a total of 17 Neanderthal and 15 Homo sapiens burials […]
