Researchers are blending Indigenous Knowledges with climate models to describe shifts in snow and ice.
Glass Sand Grows Healthy Mangroves
In places with lots of glass waste, sand made from recycled material could be another tool in the coastal restoration toolbox.
Astronauts Could Live in Structures Made from Moon Rocks
Scientists are testing “mooncrete,” a concrete analogue made from lunar regolith, as a potential material to build structures on the Moon.
Celebrating the MacGyver Spirit: Hacking, Tinkering, Scavenging, and Crowdsourcing
The MacGyver sessions allow scientist-tinkerers to have “nerd-on-nerd” discussions about do-it-yourself gadgets and gizmos.
The Long and the Weak of It—The Ediacaran Magnetic Field
A roughly 70-million-year interval of anomalously weak magnetic field during the Ediacaran period could have triggered atmospheric changes that supported the rise of macroscopic life.
When a Prayer Is Also a Climate Signal
New research in North Africa is validating calls for communal rain prayers as a means of tracking droughts in the region.
Tracing Fire, Rain, and Herbivores in the Serengeti
Increasing amounts of rain fuel grass growth across the ecosystem and, consequently, the cycles of wildfire and animal migration.
Fungi, Fertilizer, and Feces Could Help Astronauts Grow Plants on the Moon
A new study offers tantalizing evidence that filamentous fungi extending from roots, along with treated astronaut waste, could provide sufficient scaffolding to help plants grow in planetary regolith.

New research monitors how saltwater intrusion is affecting the behaviors of Shackleford Banks’s wild horses.
Sediments Hint at Large Ancient Martian Moon
Regular, alternating layers in Gale Crater may have been deposited as the result of tides raised by a moon at least 18 times the mass of Phobos, a study says.
New Tool Maps the Overlap of Heat and Health in California
CalHeatScore creates heat wave warnings for every zip code in California, using temperature data, socioeconomic indicators, and the history of emergency room visits, to predict heat-related health risk.
