Water is critical for life on Earth. Our own biology, the chemistry of our bodies, is based on it. Access to clean drinking water is a human right, and is included as one of the global 17 sustainable development goals […]
aerosol Author: Rubén Soussé Villa is pursuing a PhD in atmospheric chemistry at Barcelona Supercompting Center / Universitat Politècnica de Catalunya Mineral dust aerosols are microscopic rocky particles – for instance, sand – floating in the atmosphere. They are typically […]
A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials — like a tailor altering a suit — could be just the tool for designing the technology of a sustainable energy future. Researchers […]
In 2019, the Event Horizon Telescope (EHT) collaboration produced the first-ever image of a black hole, stunning the world. Now, scientists are taking it further. The next generation Event Horizon Telescope (ngEHT) collaboration aims to create high-quality videos of black […]
Rising seas, oxygen depletion led to mass extinction Rising seas likely contributed to high hydrogen sulfide levels and oxygen depletion that killed marine life during Earth’s Devonian period over 350 million years ago. Researchers analyzed black shale samples from the […]
According to theory of degrowth , the only way to save the planet and humanity from catastrophic collapse due to depletion of natural resources would be to radically limit, and even reduce, global production levels and, since there is still […]
Imagine a Universe that started with a huge explosion setting the beginning of space and time to the point that such concepts have no meaning until then. Imagine a Universe that, after an inflationary phase (extremely fast expansion), kept expanding […]
This column seems to be gaining a new subcategory, which we could name ‘Wokism as the latest historians’ epidemic’ or something like that. I have already written a couple of reviews of recent books that tried to awaken us from […]
Imagine a conductor or a semiconductor through which a current is flowing. Then we apply a strong transverse magnetic field. As a result, we can measure a potential difference at right angles to both the current and the field caused […]
In 1906, Alois Alzheimer, a psychiatrist and neuroanatomist, reported “a peculiar severe disease process of the cerebral cortex” to a gathering of psychiatrists in Tübingen, Germany. The case was a 50-year-old woman who suffered from memory loss, delusions, hallucinations, aggression […]
The brain tissue is filled by cells, the living units that enable function; the extracellular matrix, the scaffold wherein cells organize; and the blood vessels, which transport metabolic fuels such as oxygen and nutrients to the brain. Among the brain […]
madness Authors: Chiara Bressan, student of the European Master’s in Clinical Linguistics & Adrià Rofes, assistant professor of neurolinguistics at the University of Groningen Imagine yourself tied to a chair. You cannot move, you are fully conscious, and a strange […]

Could we feed a city on Mars? This question is central to the future of space exploration and has serious repercussions on Earth too. To date, a lot of thought has gone into how astronauts eat; however, we are only […]
