How female friendships help chimp babies survive
Female chimpanzees that forge strong, grooming-rich friendships with other females dramatically boost their infants’ odds of making it past the perilous first year—no kin required. Three decades of Gombe observations show that well-integrated mothers enjoy a survival rate of up to 95% for their young, regardless of male allies or...
Tiny Ocean Migrants Play a Massive Role in Southern Ocean Carbon Storage
Dr Katrin Schmidt is among the authors of a study which reveals for the first time that zooplankton migration contributes significantly to carbon sequestration.
New AI-Supported, High-Resolution Chesapeake Bay Watershed Stream Maps Reveal Additional Waterways and Will Help Prioritize Restoration Projects
A dataset unveiled today more than doubles the documented stream miles in the Chesapeake Bay Watershed, elevating the total from approximately 100,000 to over 200,000 miles.
Where There’s Fire, There’s Smoke
New app estimates health impacts of breathing smoke from wildfires.
Fire smoke exposure leaves toxic metals and lasting immune changes
Smoke from wildfires and structural fires doesn t just irritate lungs it actually changes your immune system.

Fighting fire with fire: How prescribed burns reduce wildfire damage and pollution
Wildfires are becoming more intense and dangerous, but a new Stanford-led study offers hope: prescribed burns—intentionally set, controlled fires—can significantly lessen their impact. By analyzing satellite data and smoke emissions, researchers found that areas treated with prescribed burns saw wildfire severity drop by 16% and smoke pollution fall by 14%....
Buried for 23,000 years: These footprints are rewriting American history
Footprints found in the ancient lakebeds of White Sands may prove that humans lived in North America 23,000 years ago — much earlier than previously believed. A new study using radiocarbon-dated mud bolsters earlier findings, making it the third line of evidence pointing to this revised timeline.
New Orleans is sinking—and so are its $15 billion flood defenses
Parts of New Orleans are sinking at alarming rates — including some of the very floodwalls built to protect it. A new satellite-based study finds that some areas are losing nearly two inches of elevation per year, threatening the effectiveness of the city's storm defenses.
