Survey completeness of a global citizen-science database of bird occurrence

There are many shortfalls in knowledge of the world's biodiversity, and one of the most basic is the lack of knowledge about where species occur geographically. This deficiency has broad ramifications for research and conservation. This study suggests the development of citizen science programs to collect data by volunteers has the potential to reduce this shortfall.

Aggressive form of breast cancer influenced by dual action of genes and RNA

Women with an aggressive, less-common type of breast cancer, known as triple-negative, versus a more common form of the disease, could be differentiated from each other by a panel of 17 small RNA molecules that are directly influenced by genetic alterations typically found in cancer cells.

Pushy robots learn the fundamentals of object manipulation

Researchers have compiled a dataset that captures the detailed behavior of a robotic system physically pushing hundreds of different objects. Using the dataset — the largest and most diverse of its kind — researchers can train robots to 'learn' pushing dynamics that are fundamental to many complex object-manipulation tasks, including reorienting and inspecting objects, and uncluttering scenes.
