 Congratulations to the high school, undergraduate, and graduate students who participated in the 2018 Student Research Showcase! This online competition hones students' science communication skills by challenging them to create an abstract, slideshow, and video about their research for audiences with varying degrees of expertise. Division and section winners have been announced. A group of Sigma Xi members judged these presentations. Public voting is now open for the People’s Choice Award winner.

Oil drilling 1,500 meters under the sea is complicated, and the Deepwater Horizon disaster still offers valuable lessons.

Biochemists at the University of Illinois have isolated a protein supercomplex from a bacterial membrane that, like a battery, generates a voltage across the bacterial membrane. The voltage is used to make ATP, a key energy currency of life. The new findings, reported in the journal Nature, will inform future efforts to obtain the atomic structures of large membrane protein supercomplexes.
