NSF-funded researchers have discovered that climate change, warmer temperatures and earlier snow melt are causing flowers to bloom earlier. These changes are affecting at least three types of bumble bees that live in higher altitudes and rely on these blooms to live and thrive.

The genetic material of the HIV virus is encased in multiple structures that hide it from the host immune system. The capsid, in blue, protects the virus after it enters a cell and shuttles it to the nucleus, where it completes the process of infection. More about this image A ...

A Bombus balteatus bumblebee queen collects nectar from an alpine clover (Trifolium parryi). The buzzes of bees flying from flower to flower tell scientists how much pollination the clover population is getting over time and predict seed production in these alpine wildflowers. ...

Georgia State University researchers have found a potential safeguard against dangerous wobbling of pedestrian bridges. The key factors: biomechanically inspired models of pedestrian response to bridge motion and a mathematical formula to estimate the critical crowd size at which bridge wobbling ...
