What do cancer cells, weeds, and pathogens have in common? They all evolve resistance to the treatments that are supposed to eliminate them. However, researchers developing the next generation of antibiotics, herbicides, and anti-cancer therapeutics rarely come together to explore the common evolutionary principles at work across their different biological systems. The new American Academy of Microbiology report "Moving Targets: Fighting Resistance in Infections, Pests, and Cancer" concludes...

Ecology and Phylogenetics-New Views of Earth's Biodiversity
2012-08-06 13:38:37

Scientists report new look at 'patterns in nature' in special issue of journal Ecology View patterns of nature in this photo gallery. Patterns in nature are in everything from ocean currents to a flower's petal. Scientists are taking a new look at Earth patterns, studying the biodiversity of yard plants in the U.S. and that of desert mammals in Israel, studying where flowers and bees live on the Tibetan plateau and how willow trees in America's Midwest make use of water. They're...

Mother Nature Inspires 1-pound Boat That Could Float 1,000 Pounds
2012-03-26 02:23:42

Combining the secrets that enable water striders to walk on water and give wood its lightness and great strength has yielded an amazing new material so buoyant that, in everyday terms, a boat made from 1 pound of the substance could carry five kitchen refrigerators, about 1,000 pounds. One of the lightest solid substances in the world, which is also sustainable, it was among the topics of a symposium held Sunday at the 243rd National Meeting & Exposition of the American Chemical...

Classic Model For Ecological Stability Revised
2012-02-20 04:32:08

Predator-prey relationships stabilize diverse ecosystems, according to calculation A famous mathematical formula which shook the world of ecology 40 years ago has been revisited and refined by two University of Chicago researchers in the current issue of Nature. In 1972, physicist Robert May rankled ecologists by publishing a simple model describing the relationship between diversity and stability in a theoretical ecosystem. Though ecologists had long believed that richer, more diverse...

(Ivanhoe Newswire)– According to the U.S. Centers for Disease Control, about out of 3 U.S. adults are obese and that number continues to grow.  Now some experts are looking at brains instead of bellies to find out why. Diabetes researchers at the University of Cincinnati are drawing attention to the biological factors that contribute to the rising rates of obesity and exploring options to reduce body weight. "While we don't usually think of it this way, body weight is...

An editorial authored by University of Cincinnati (UC) diabetes researchers to be published in the Feb. 7, 2012, issue of the journal Cell Metabolism sheds light on the biological factors contributing to rising rates of obesity and discusses strategies to reduce body weight. According to the U.S. Centers for Disease Control, about one-third of U.S. adults are obese, a number that continues to climb. "While we don't usually think of it this way, body weight is regulated. How much we...

On Earth all biology is subjected to gravity. Some biological systems require gravity for correct orientation (geotropism: plants grow up, roots grow down). In the absence of gravity even human biology is affected: astronauts lose bone density at 1-2% a month rather than the usual 1-2% a year on Earth. But the effects of gravity on cellular processes are less well understood. New research published in BioMed Central's open access journal BMC Genomics has used diamagnetic levitation to...
