Quantum simulation, a concept that once seemed like science fiction, is now revolutionizing the way physicists study the quantum world. The idea, famously suggested by Richard Feynman in the 1980s, is to use a controllable quantum system to mimic the behaviour of another system that is too complex to study directly. Over time, researchers have […]
Author: Albert HiuKa Fok, Postdoctoral Fellow in Neuroscience, McGill University The puzzle of memory has intrigued philosophers and intellects for a very long time. Plato and Aristotle believed that memory was found only in the realm of the soul and the mind, but there was nothing corporeal or physical about it. Memory is closely tied […]
Using the 10.4-m Gran Telescopio Canarias (GTC), astronomers have detected methane in the atmosphere of WISEA J181006.18−101000.5—the closest T dwarf to Earth. Brown dwarfs are intermediate objects between planets and stars. Astronomers generally agree that they are substellar objects occupying the mass range between 13 and 80 Jupiter masses. One subclass of brown dwarfs (with […]
Eating disorders such as anorexia nervosa affect up to 70 million people worldwide. In particular, despite its prevalence and long-term duration, there are no effective pharmacological treatments for anorexia. This may change in the future if recent results in mice transfer appropriately to humans, as a “hunger” peptide appears to revert weight loss in mice […]
Asteroid samples reveal ancient salty incubators Samples from asteroids Ryugu and Bennu have revealed the presence of salts, indicating that salty water environments were common in the early solar system. This finding suggests that such environments could have been incubators for life’s building blocks, a discovery that highlights the potential for organic evolution on asteroids […]
Imagine a world where light, instead of merely bouncing off surfaces or passing through transparent materials, is controlled in a completely new and unexpected way. Scientists have recently taken a major step in this direction by discovering what is called a “photonic axion insulator.” While this term might sound complicated, the underlying idea is both […]
Author: Ignacio López-Goñi, Professor of Microbiology, Universidad de Navarra On March 11 2020, the World Health Organization declared COVID-19 a pandemic. According to official data there have been more than 770 million cases of COVID, which have caused over 7 million deaths in 231 countries – almost 2.2 million of them in Europe. Other reports […]
Past neuroscience and psychology studies have shown that people’s expectations of the world can influence their perceptions, either by directing their attention to expected stimuli or by reducing their sensitivity (i.e., perceptual acuity) to variations within the categories of stimuli we expect to be exposed to. While the effects of expectations on perceptions are now […]
Acute myeloid leukemia (AML) is a disease of older persons that has a dismal outcome and patients unfit for intensive chemotherapy exhibit a median survival of only 5 to 10 months . However, the therapeutic landscape of AML is changing with the appearance of new-targeted drugs such as BH3 mimetics that inhibit prosurvival BCL2 family […]
Genetic erosion poses hidden threat to species survival Research on the regent honeyeater, a critically endangered bird from southeastern Australia, reveals that despite severe population decline, the species retains high genetic diversity. Through whole-genome sequencing and ecological modeling, the study underscores the delayed impact of genetic erosion and the importance of integrating genetic data over […]
