Pioneer High School and Sharyland High School in Texas are offering students a 40-hour course to help them earn certification to pilot a drone. Students in this portion of the career and technical education program will then study the rest of the year how drones are used in damage assessments and search and rescue operations.

NASA and the National Science Foundation are backing a study to find out what happens to carbon captured by phytoplankton after the organisms are eaten or die and how that affects Earth's climate. The Export Processes in the Ocean from Remote Sensing expedition, or EXPORTS, will involve more than 100 scientists and will explore dark regions of the ocean between 650 and 3,300 feet, or 198 to 1,006 meters, deep with two research vessels, underwater robots and satellite images.

A once-dead gene in elephants that came back to life about 59 million years ago when the animals' ancestors started getting bigger has been linked to their ability to fend off cancer, according to findings published online by Cell Reports. The LIF6 gene works with the TP53 gene, signaling damaged cells to destroy themselves before they turn into cancer cells, researchers say.

Targeting the brain with well-timed electric shocks while subjects are asleep may give memory a boost, a study published in The Journal of Neuroscience suggests. Participants wore stimulation caps that monitored their brain activity and delivered zaps when the subjects' brains exhibited slow-wave oscillations, and their ability to find previously viewed hidden targets in new scenes improved, suggesting a memory boost.

The big toe was among the last things to evolve on the feet of human ancestors as they transitioned to bipedalism, according to a study published in the Proceedings of the National Academy of Sciences. "The big toe could still be used for grasping, as our ancestors spent a fair amount of their time in the trees, before becoming fully committed to walking on the ground," said study leader Peter Fernandez.

Alveolar macrophages, immune cells found in the lungs, can be damaged by vaping, according to findings published in Thorax. Researchers tested lung tissue in eight nonsmokers and found that exposure to vapor from e-cigarette liquid over a 48-hour period was toxic to the lung cells, spurring the release of inflammatory cytokines and inhibiting phagocytosis.
