As far as anyone can tell, the cold-water crayfish Faxonius eupunctus makes its home in a 30-mile stretch of the Eleven Point River and nowhere else in the world. According to a new study, the animal is most abundant in the middle part its range, a rocky expanse in southern Missouri – with up to 35,000 cubic feet of chilly Ozark river water flowing by each second.

Wind and solar power could generate most but not all electricity in the United States, according to an analysis of 36 years of weather data by Carnegie’s Ken Caldeira, and three Carnegie-affiliated energy experts: Matthew Shaner, Steven Davis (of University of California Irvine), and Nathan Lewis (of Caltech).

Access to wood fuels for cooking must be considered when formulating policy to deal with food insecurity in sub-Saharan Africa, according to researchers who advocate expanding the effort to improve wood-fuel systems and make them more sustainable.

People who swim, bathe or take part in water sports in the sea are substantially more likely to experience stomach bugs, ear aches and other types of illness than those who do not.

The island chain of Hawaii consists of several volcanoes, which are fed by a "hotspot". In geosciences a "hotspot" refers to a phenomenon of columnar shaped streams, which transport hot material from the deep mantle to the surface. Like a blow torch, the material burns through the Earth's crust and forms volcanoes. For a long time, it was assumed that these hotspots are stationary. If the tectonic plate moves across it, a chain of volcanoes evolves, with the youngest volcano at one end, the oldest at the other.

Times are tough for 31 of Michigan’s 45 varieties of freshwater mussels. Sporting evocative names like wavy-rayed lampmussel and round pigtoe, these residents of the state’s rivers are imperiled by habitat disruption and pollution and are also threatened by climate change.

Twelve-foot metal poles with long outstretched arms dot a Midwestern soybean field to monitor an invisible array of light emitted by crops. This light can reveal the plants’ photosynthetic performance throughout the growing season, according to newly published research by the University of Illinois.

Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago. Intriguingly, the results are forcing astronomers to consider that they may be seeing evidence of something unexpected at work in the universe.

Cleaning up beaches could boost local economies in addition to preserving natural treasures and animal habitats.

In southern California’s Orange County alone, the economic benefits of beach cleanup could range from $13 per resident in a three-month period if debris were reduced by 25 percent to $42 per resident with a 75 percent drop in plastics and other trash along the oceanfront, according to a new study. That could mean up to a $46 million boost to the county’s economy in just one summer.

A University of Guelph researcher has discovered one of the factors behind nerve cell death in Parkinson’s disease, unlocking the potential for treatment to slow the progression of this fatal neurodegenerative disorder.
