Certain plants, including many of the ones we like to eat, store their pollen deep in the flower where bees can’t access it. This could be a real problem, since bees play a crucial role in pollinating plants, helping them to produce the fruits we love to eat. No need to worry—bumblebees have our backs. They’ve adapted a secret weapon aka buzz pollination, or sonication, to unlock that pollen. The bumblebee attaches to the flower and vibrates its muscles with forces up to 30 g’s! This produces the buzzing sound and shakes the pollen right onto the bumblebee, which then pollinates other flowers. So the next time you’re eating blueberries, thank the bumblebee and its superpower buzz.

Bolt has a lot more to teach you about bumblebees and has partnered with National Geographic grantee Neil Losin to make the film “A Ghost in the Making: Searching for the Rusty-Patched Bumble Bee.” Be sure to check out it out at http://www.rustypatched.com.

These Indoor Wildfires Help Engineers Study the Real Thing | National Geographic

See researchers start their own fires to study how wildfires burn. Wildfires can be a devastating force that are hard to predict, but a team of researchers from the University of California, Riverside create these fires in their lab to understand how they burn and spread. The researchers prepare different types of forest brush and add other elements such as wind and humidity that affect fire behavior. The data collected is then used to predict how wildfires will behave under certain conditions. By working with the U.S. Forest Service, the researchers hope that their experiments will help firefighters understand and manage real fires.
