Computer model can predict COVID-19’s spread

A study of how 98 million Americans move around each day suggests that most infections occur at “superspreader” sites that put people in contact for long periods, and details how mobility patterns help drive higher infection rates among minority and low-income populations.

Researchers model eruption on Jupiter’s moon Europa

A new model shows how brine on Jupiter’s moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings, which are important for the upcoming Europa Clipper mission, may explain cryovolcanic eruptions across icy bodies in the solar system.

Forecasting ecosystem changes through DNA

The rapid, low-cost technique is the first to analyze DNA left behind in animals’ feces to map out complex networks of species interactions in a terrestrial system. It could help redefine conservation as we know it, identify otherwise hard-to-find species and guide a global effort to rewild vast areas.

Cape Town’s ‘Day Zero’ drought a sign of things to come

Using new high-resolution simulations, researchers conclude that climate change made the Cape Town ‘Day Zero’ drought five to six times more likely and suggest extreme drought events could become common in southwestern South Africa by the end of the 21st century.

Microlab tests for COVID-19 in 30 minutes

Using “lab on a chip” technology, Stanford engineers have created a microlab half the size of a credit card that can detect COVID-19 in just 30 minutes.

When algorithms compete, who wins?

Over time, prediction algorithms become specialized for an increasingly narrow slice of the population, and the average quality of their predictions declines.
