When millions of people died in Europe during the Black Death, biodiversity suffered too, new research suggests. The findings suggest that human activities once promoted biodiversity in the landscape — and experts say we could use these findings to boost biodiversity in our modern agricultural landscapes. The 14th century was a tumultuous time for the […]

When temperatures spike, California redwoods slow down photosynthesis, new research has found. This finding has serious implications for the long-term survival of the iconic trees in a warming world, and their role in storing carbon from the atmosphere. California redwood (Sequoia sempervirens) forests are among the largest aboveground carbon stores on the planet. These towering

Recent research challenges a long-standing idea about how the brain develops: Rather than arising from a single source, the brain may emerge from two distinct populations of cells, the study finds. “The brain appears as one organ,” said study co-author Kyle Loh, an associate professor of developmental biology at Stanford University. “However, we discovered that
