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 […]

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.

WHEN will you get a COVID-19 vaccine?

Quanta’s In Theory video series returns with an exploration of the mysterious mathematical pattern found throughout nature. Read about the new season debut here: https://www.quantamagazine.org/the-un… Directed and animated by Emily Driscoll for Quanta Magazine

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.

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 […]

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 […]

Raging fires throughout the U.S. and Australia over the past year have put vulnerable species at risk. But not all blazes are devastating—in fact, fire can promote biodiversity. In grasslands, fires prevent trees and roots from taking hold. This allows grazing animals the space and vegetation they need to thrive. As the pattern of wildfires […]

Giant hornets, which were detected in North America for the first time last year, can devastate colonies of the most common type of honey bee. But in Asia, where the fearsome predators are native, honey bees mount a vigorous defense with intimidating behaviors and coordinated counterstrikes. Now, researchers have discovered that Asian bees employ another, […]

The inside story of the DeepMind team of scientists and engineers who created AlphaFold, an AI system that is recognised as a solution to «protein folding», a grand scientific challenge for more than 50 years.
