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 […]
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 […]
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 […]
Scientists have created the world’s first monkey embryos containing human cells in an attempt to investigate how the two types of cell develop alongside each other. The embryos, which were derived from a macaque and then injected with human stem cells in the lab, were allowed to grow for 20 days before being destroyed. We […]
Mental wandering, sometimes referred to as off-task thinking or, colloquially, going on autopilot, is the experience of thoughts not staying on a single topic, but jumping without control from one thing to another. This is particularly striking when we are engaged in a task that requires focus. A common place for mental wandering is when […]
A middle-aged white man raises his sword to the skies and roars to the gods. The results of his genetic ancestry test have just arrived in his suburban mailbox. His eyes fill with tears as he learns that he is “0.012% Viking”. These are the scenes from a video advertisement for the TV-series Vikings. This […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission.

If you ask people to list the most intelligent animals, they’ll name a few usual suspects. Chimpanzees, dolphins and elephants are often mentioned, as are crows, dogs and occasionally pigs. Horses don’t usually get a look in. So it might come as a surprise that horses possess an unusual skill, widely considered an indicator of […]
When Cern’s gargantuan accelerator, the Large Hadron Collider (LHC), fired up ten years ago, hopes abounded that new particles would soon be discovered that could help us unravel physics’ deepest mysteries. Dark matter, microscopic black holes and hidden dimensions were just some of the possibilities. But aside from the spectacular discovery of the Higgs boson […]
Quick simulations of space orbits and trajectories are essential in different aspects of space engineering, from the optimization of trajectories and orbit transfers, to the determination of the orbits themselves, altitude control, and gravitational modelling. Although the preliminary analysis of satellite space orbits can be done without extensive simulations, to represent the dynamical states of […]
