When you think of the world's greatest athletes, names like Usain Bolt generally spring to mind, but scientists have discovered the best athletes could well be found in the water, covered in scales.

Scientists have discovered that fish are far more effective at delivering oxygen throughout their body than almost any other animal, giving them the athletic edge over other species.

A team of international researchers, including James Beasley, assistant professor of wildlife ecology at the University of Georgia Savannah River Ecology Laboratory and the Warnell School Forestry and Natural Resources, has discovered abundant populations of wildlife at Chernobyl, the site of the 1986 nuclear accident that released radioactive particles into the environment and forced a massive evacuation of the human population.

One of the most frustrating claims by people raising money promoting an environmental apocalypse has been that species are about to go extinct or diversity will be lost. It leads to rampant distrust in science because advocates know if their side is spinning facts to suit an agenda, the science side might be too.

Rose gardeners have a lot to say about aphids. Some may advise insecticides as a way to manage an infestation, but others will swear by live ladybugs (natural predators of aphids). The latter is more environmental friendly, and once the ladybugs run out of food to eat, they move on.

Hurricane Joaquin continued to intensify in the Bahamas on October 1 and NASA and NOAA satellites have been providing valuable data on the storm. NASA's GPM and Terra satellites and NOAA's GOES-East satellite provided rainfall, cloud extent, cloud height and other data to forecasters. Joaquin became a major hurricane today, October 1, reaching Category 3 status on the Saffir-Simpson Wind Scale.

Months of warning signs from Mauna Loa, on Hawaii's Big Island, prompted the U.S. Geological Society to recently start releasing weekly updates on activity at the world's largest active volcano.

Goldenrod, Himalayan balsam, Chinese windmill palm: three plants, one problem. All are native to continents other than Europe, but were introduced to Switzerland as garden or ornamental plants. At some point they "escaped" into the wild, where they now threaten the native flora.

Local habitat variability in northwest streams can help shield coastal cutthroat trout from the effects of forest harvest and climate change, a new U.S. Forest Service-led study has found.

The study--one of few to explore fish population response to both harvest activities and a changing climate-- revealed that trout in four neighboring Oregon streams respond differently to these disturbances based on the features of the streams where trout live. The study is published in the journal PLOS ONE.

To better understand global weather patterns and increase scientific collaboration between the U.S. and India, researchers supported by the Office of Naval Research (ONR) have completed a month-long cruise studying summer monsoon conditions in the Bay of Bengal.

A new review claims that drinking too many sugar-sweetened beverages, which contain added sugars in the form of high fructose corn syrup or table sugar (sucrose), can lead to excess weight gain and a greater risk of developing type 2 diabetes and cardiovascular disease.

The review was engineered to implicate fructose in the development of these conditions.

An analysis of medical costs associated with atherosclerotic lower extremity peripheral artery disease, a dangerous condition in which a buildup of plaque in the arteries restricts blood flow to the legs and feet, found that health care costs in one year were $18,000 higher in smokers with the condition than non-smokers with the condition.

Within one year, 49 percent of the tobacco users with PAD in the study were hospitalized, a hospitalization rate 35 percent higher than nonusers.

About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it, providing what researchers believe may be the oldest evidence on Earth of a dreaded and historic killer - an ancient strain of the bubonic plague.

If indeed the fossil bacteria are related to plague bacteria, Yersinia pestis, the discovery would show that this scourge, which killed more than half the population of Europe in the 14th century, actually had been around for millions of years before that, traveled around much of the world, and predates the human race.

Researchers from the University of Exeter believe they have solved one of the biggest puzzles in climate science. The new study, published in Nature Geoscience, explains the synchrony observed during glacial periods when low temperatures in the Southern Ocean correspond with low levels of atmospheric carbon dioxide (CO2).

The interdisciplinary study, carried out in collaboration with the University of Tasmania, demonstrates how a reconfiguration of ocean circulation can result in more carbon being stored in the deep ocean that previously thought.

A proof-of-concept study finds that it is possible to identify an individual's ancestral background based on his or her fingerprint characteristics - a discovery with significant applications for law enforcement and anthropological research.

Black rice has a rich cultural history; called "Forbidden" or "Emperor's" rice, it was reserved for the Emperor in ancient China and used as a tribute food. In the time since, it remained popular in certain regions of China and recently has become prized worldwide for its high levels of antioxidants. Despite its long history, the origins of black rice have not been clear. Black rice cultivars are found in locations scattered throughout Asia. However, most cultivated rice (species Oryza sativa) produces white grains, and the wild relative Oryza rufipogon has red grains.
