“At a certain point, patterns appear: stripes, zigzags and rings,” said co-author Ned Wingreen, the Howard A. Prior Professor in the Life Sciences and a professor of molecular biology and the Lewis-Sigler Institute for Integrative Genomics.

A simulation system invented at MIT to train driverless cars creates a photorealistic world with infinite steering possibilities, helping the cars learn to navigate a host of worse-case scenarios before cruising down real streets.  

Heavy rain in March drenches parched land in southwestern Queensland.

Earth’s land is covered by a range of different types of vegetation, from forest and marsh to crops and bodies of water, as well as the artificial surfaces that are an increasingly common feature of our landscape.

After nearly two decades, the Sun has set for NASA’s SOlar Radiation and Climate Experiment (SORCE), a mission that continued and advanced the agency’s 40-year record of measuring solar irradiance and studying its influence on Earth’s climate.

NASA’s new 3-dimensional portrait of methane concentrations shows the world’s second largest contributor to greenhouse warming, the diversity of sources on the ground, and the behavior of the gas as it moves through the atmosphere.

East Antarctica’s Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.

A frightening new threat cascades around the world, upending familiar routines, disrupting the global economy, and endangering lives.
