Paralyzed man writes on screen with his mind A man paralyzed from his neck down was able to imagine writing words and have them appear on a screen. Researchers attached a pair of electrodes to an area of the man’s brain associated with finger and hand movement, and after he imagined he was writing the […]
Two-dimensional (2D) materials are extraordinary for two main reasons. One is the set of mechanical properties that makes those materials a versatile playground where multiple modelling objects are possible, from the thinnest membranes with minuscule bending rigidity to very stiff plates, all with very reproducible parameters. The other reason is that both the electronic and […]
By now, we’re all experts in the common symptoms of the oh so omnipresent COVID-19 – say, for example, dry coughing, fever, and loss of smell (Sauer, 2021). While we’re all hyper-vigilant about these symptoms, a new factor behind the spread of this virus may be on the rise: language. That’s right: new research suggests […]
People might once have considered oxygen a human right. But the pandemic has revealed that access to oxygen – in a pure form, for medical use – is a luxury in most low and middle-income countries. Getting access to pure oxygen for medical treatments is a complicated, expensive and often very dangerous business. The current […]
Cerebellum may have been key to human evolution Researchers have found differences between the human cerebellum and those of chimpanzees and rhesus macaques that may have been fundamental to human evolution. Scientists examined DNA from the prefrontal cortices and cerebellums of all three and found that methylation patterns were different in humans, especially in the […]
Real life is sometimes very different from laboratory settings. Take superconductivity, for example. In order to reach, it you either need extremely low temperatures, extremely high pressures or a combination of both; something that makes very difficult to conceive an everyday application out of a laboratory. Something similar happens with other new materials, but in […]
“There is something at work in my soul, which I do not understand.” ― Mary Wollstonecraft Shelley (1797-1851), Frankenstein or The Modern Prometheus, 1818 Increasing advances in material’s science have enabled the design and production of materials capable of inducing specific cell behaviors, such as proliferation, migration or differentiation. Consequently, we are now able to […]
Original: Eduardo Angulo (2017) Preparados para matar: algunas ideas para el debate. Translated and adapted by Julio Nicanor Ozores, M.D. “…the proper application of Darwinian thinking to human issues- of mind, language, knowledge, and ethics, for instance- illuminates them in ways that have always eluded the traditional approaches, recasting ancient problems and pointing to their […]
Venus’ core size is on par with Earth’s The size of Venus’ core is similar to that of Earth’s, with a diameter of about 7,000 kilometers, according to findings published in Nature Astronomy. Researchers calculated the core’s size using radio waves sent via California’s Goldstone Solar System Radar and charting their echoes with the Green […]
Euclid is an ESA mission to map the geometry of the Universe and better understand the mysterious dark matter and dark energy, which make up most of the energy budget of the cosmos. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters […]
