We started this series discussing the basic ingredients of the Universe: events, spacetime, causality. In the last chapter , we introduced massive objects (and thus, matter), which appear as a generalization of the so-called photon box. As it moves, any object traces a path. Physicists call it worldline . We established that a massive object […]
Altered Ebola virus induces immune response in monkeys Researchers found that exposure to a slightly altered Ebola virus induced an immune response in monkeys that protected them from the parent virus. The goal is to produce a drug that knocks out the VP35 protein in the Ebola virus, although researchers cautioned that it may not […]
The concept of mean free path is very simple and straightforward: the average distance travelled between collisions by the molecules in a gas, the electrons in a metallic crystal, the neutrons in a moderator, etc. Assuming a couple of things about, for example, how elastic collisions are, it is not difficult to arrive to formulas […]
Strategic decision is the object of study for Game Theory, a discipline that started officially with the book The Theory of Games and Economic Behavior, by John von Neumann and Oskar Morgenstern . For non-cooperative games, i.e., games in which individuals make decisions individually and with no strings attached, the book was restricted to zero-sum […]
Good news everyone! A newly discovered type of hepatic cell might hold the key to repair all those old fatty livers without needing a transplant. And not only those but also those of people suffering from side effects of medication, cancer etc etc But let’s try not to get ahead of ourselves. A team of […]
Hubble snaps stunning photo of Saturn Saturn and its rings shine in an image captured by the Hubble Space Telescope and released by NASA and the European Space Agency on Thursday. The image, taken on June 20, also shows four of Saturn’s moons: Enceladus, Mimas, Janus and Tethys. Space.com Assessing the long reach of microplastics […]
Cortical neurons often fire together as a group, rather than independently, and these coactive groups, also known as neuronal ensembles (or chains, assemblies, attractors, clicks, motifs, songs, bumps, etc.), could constitute emergent functional units of the brain, as modular building blocks of memories, thoughts, motor programs, computations, or perceptual or mental states. In order to […]
Packaging is essential to preserve the food quality and safety and to extend the shelf life of the stored product reducing the food waste. In this sector, plastics are the material of choice because they are cheap, lightweight and easy to process. The main requirement for packaging materials is to maintain the food in good […]
Scientific disinformation about climate change is having a great impact especially in countries like the United States (USA). Misinformation about this topic and about scientific issues in general, not only confuses the population and discredits scientific findings but also paralyzes evidence-based policies. Farrell et al (2019) provide a series of examples and strategies that can […]
Einstein’s theory helps map pulsar’s beams Researchers used Einstein’s theory of general relativity to map the structure of the pulsar PSR J1906+0746 and, by doing so, they also confirmed the theory. Astronomers observed the pulses coming from PSR J1906+0746 over the course of 14 years. ScienceAlert Whale’s song can reveal where it has been The […]
