Sahara Author: Evgenii Krestianinov, PhD candidate, Research School of Earth Sciences, Australian National University In May 2020, some unusual rocks containing distinctive greenish crystals were found in the Erg Chech sand sea, a dune-filled region of the Sahara Desert in southern Algeria. On close inspection, the rocks turned out to be from outer space: lumps […]
Social networks Author: Martha R. Villabona works at Subdirección General de Cooperación Territorial e Innovación Educativa of the Spanish Ministry of Education and Vocational Training, where she coordinates the area of multiple literacies. The American Psychological Association (APA) states that the use of social networks is either harmful or beneficial for young people . In […]
Just like our hands, certain organic molecules relate to each other like an image and its reflection – a phenomenon that chemists call “chirality” or “handedness”. The two mirror images of the same molecule, namely both enantiomers, often possess different biological properties. This is key, for example, for drug discovery, as many times only one […]
T-cell Author: Marta Irigoyen is a postdoctoral researcher at CIC bioGUNE T-ALL is an aggressive malignancy which results from the leukemic transformation of T-cell progenitors into tumor cells. It is widely accepted that complex interactions between T-ALL cells and their surrounding microenvironment contribute to disease and may regulate quiescence, survival and self-renewal of cancer cells […]
Reduced cancer risk tied to short bouts of physical activity A study found that a minimum of 3.4 minutes and 3.7 minutes of vigorous intermittent lifestyle physical activity per day were associated with a 17% lower total cancer incidence risk and 28% lower physical activity-related cancer incidence risk, respectively. Full Story: MedPage Today Polyethylene plastic […]
Phase transitions and their related phenomena lie at the core of modern statistical mechanics and condensed matter physics. At equilibrium, an intriguing aspect of second-order phase transitions is that systems with distinct order parameters can be described by the same set of static critical exponents, a hallmark of universality. Thomas Kibble’s research on phase transitions […]
Niño Author: David Armstrong McKay, Researcher in Earth System Resilience, Stockholm University The UN World Meteorological Organisation (WMO) has confirmed it: El Niño conditions have arrived and are expected to become moderate to strong as they develop over the coming year. El Niño is the hot phase of a natural fluctuation in the Earth’s climate […]
Scientists working on the Dark SRF experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have demonstrated unprecedented sensitivity in an experimental setup used to search for theorized particles called dark photons. Researchers trapped ordinary, massless photons in devices called superconducting radio frequency cavities to look for the transition of those photons into […]
inheritance Author: Juan F. Trillo, PhD in Linguistics and Philosophy (U. Autónoma de Madrid), PhD in Literary Studies (U. Complutense de Madrid). The question about to what extent there is a direct relationship between the language spoken by a specific population and its genetic heritage has been controversial for some time, mainly due to the […]
Astronomers discover first evidence of “Trojan planet” Scientists have spotted the first evidence of a “Trojan planet” that shares the same orbit around a star as another planet. Astronomers believe that Trojan planets form when dust clouds are held into stable material from the gravitational pull of a star and other planet and may be […]
