STARLINK de Elon Musk: ¿El fin del cielo nocturno?
La constelación de satélites de Elon Musk, Starlink, amenaza con llenar de luces nuestros cielos y dejarnos sin noche y estrellas para siempre. ¿Cuánto de verdad hay en ello?
2020’s Biggest Breakthroughs in Biology
In 2020, the study of the SARS-CoV-2 virus was undoubtedly the most urgent priority. But there were also some major breakthroughs in other areas. We’d like to take a moment to recognize them. 1. This year, we learned that we had severely underestimated the human brain’s computing power. Researchers are coming to understand that even […]
2020’s Biggest Breakthroughs in Physics
This year, two teams of physicists made profound progress on ideas that could bring about the next revolution in physics. Another still has identified the source of a longstanding cosmic mystery. 1. Here’s an extremely brief version of the black hole information paradox: Stuff falls into a black hole. Over time — a long, long […]
Why Masks Work BETTER Than You’d Think
This video is about how masks (whether surgical, or N95, or cloth) are counterintuitive and actually work much better epidemiologically than one might expect. Masks do double-duty, and the fraction of interactions with masks is much higher than the fraction of people wearing masks, so partially adopted, partially effective masks are able to reduce the […]
How To Tell If We’re Beating COVID-19
This video is a collaboration with Aatish Bhatia about how to see the COVID-19 tipping point – we present a better way to graph COVID-19 coronavirus cases using a logarithmic scale in «phase space» – plotting the growth rate against the cumulative cases, rather than either of these against time.

Bill Gates: How to fund the green revolution | The Economist
Bill Gates outlines his vision for a global green revolution. He tells Zanny Minton Beddoes, our editor-in-chief, how renewable energy is merely the first step in combatting climate change.
Watch a Robot AI Beat a World Class Curling Competitor
On the ice, a machine-learning system often triumphed over high-level South Korean players. Artificial intelligence still needs to bridge the “sim-to-real” gap. Deep-learning techniques that are all the rage in AI log superlative performances in mastering cerebral games, including chess and Go, both of which can be played on a computer. But translating simulations to […]
What if the Universe was different?
If gravity were just a little stronger in our own three-dimensional world, the curvature of spacetime would be greater, and matter could more easily collapse in on itself. This arrangement would make stars, galaxies and planets extremely diminutive, compared with the ones in our reality. Not only would we have less space on Earth, but […]
Un algoritmo inspirado en los caminos descartados por las hormigas
Agencia SINC Es conocido que las hormigas dejan a su paso un rastro de feromonas, lo que permite al resto del hormiguero seguir la misma ruta. Rutas más cortas al nido permiten un paso más frecuente de hormigas: en consecuencia, acumulan mayor rastro de feromonas y quedan reforzadas positivamente frente a las otras rutas. Esto permite a […]
