Bees' Electricity Makes Flowers Release Their Scent
Scientists at the University of Bristol, Rothamsted Research, and Cardiff University have determined that the electrical charge created by visiting bumblebees stimulates some flowers to release more of their sweet-smelling scent.

The authors posit the trait is expressed in plants to ensure they attract pollinators as opposed to other bugs that might not be as beneficial to the plant's goals: setting fruit!

The electrical charge on a bumblebee—somewhere in the region of 120 picoCoulombs (pC)—is incredibly small but the team found a charge of 600 pC, or about the same as five bee visits, was enough to induce a species of violet petunia, Petunia integrifolia, to markedly release more scent.

Get Astronauts Home from Mars: Turn Carbon Dioxide to Methane
Engineers at the University of Cincinnati are developing new ways to convert Carbon Dioxide to Methane. The technology could be used to get astronauts home from Mars.

UC College of Engineering and Applied Science assistant professor Jingjie Wu and his students, including lead author and UC doctoral candidate Tianyu Zhang, are experimenting with different catalysts such as graphene quantum dots—layers of carbon just nanometers big—that can increase the yield of methane.

Wu's students are using different catalysts to produce not only methane but ethylene. Called the world's most important chemical, ethylene is used in the manufacture of plastics, rubber, synthetic clothing, and other products.
