CubeSats prove their worth for scientific missions

Only a few years ago, the astronomy and heliophysics communities were skeptical about whether CubeSats could reliably obtain scientific data. But these breadloaf-size satellites have proven their ability to return useful data. During the APS April Meeting 2019, Christopher S. Moore will describe how the twin Miniature X-ray Solar Spectometer CubeSats measure soft X-rays from…

Smart antioxidant-containing polymer responds to body chemistry, environment

A new drug-delivery system that contains crystalized catechin -- an antioxidant found in green tea and fruit -- can sense trouble and respond by releasing antioxidant to restore a normal heart rate to water fleas undergoing cardiac stress brought on by high oxidant levels.

Historic logging site shows first human-caused bedrock erosion along an entire river

The author's 45-pound dog gives a sense of the size of the bedrock boulders being eroded from the side of the Teanaway River. The previous floodplain is just visible at the top of the frame. Credit: Sarah Schanz/Indiana University Geologic time is supposed to be slow, and the most solid object should be bedrock. But…

Entomologists uncover Florida fire ant matriarchy

This is Kip Lacy in entomology professor Ken Ross' lab at the Riverbend Research Lab North. Credit: Andrew Davis Tucker/UGA In most colonies, ants work in service of a single reproductive queen, but that's not always the way ant societies function. Researchers at the University of Georgia have found colonies of tropical fire ants, native…

Scientists use eBird data to propose optimal bird conservation plan

This is a Canada warbler. Credit: Cameron Rognan/Cornell Lab of Ornithology A new paper published today in the journal Nature Communications shows a blueprint for conserving enough habitat to protect the populations of almost one-third of the warblers, orioles, tanagers, and other birds that migrate among the Americas throughout the year. For the research, an…
