Babies born to native high-altitude mothers have decreased risk of low birth weight

BETHESDA, Md. (May 18, 2009) Pregnant women who are indigenous to the Andes Mountains deliver more blood and oxygen to their fetuses at high altitude than do women of European descent. The study helps explain why babies of Andean descent born at high altitude weigh more than European babies born a...

K-State researchers work with university in Ghana to create biofuels from native tree seeds

A short rainy season and desertification make growing food in northern Ghana difficult enough. It doesn't help that in this western African country there is little fuel available to power tractors for planting crops or to power grain milling. Researchers at Kansas State University think that th...

River damming leads to dramatic decline in native fish numbers

Damming of the Colorado River over the last century, alongside introduction of game fish species, has led to an extensive decline in numbers of native fish whilst introduced species have flourished. Scientists have found that physical changes which occur to a river when it is dammed have had an a...

Climate change could severely impact California's unique native plants

Berkeley -- The native plants unique to California are so vulnerable to global climate change that two-thirds of these "endemics" could suffer more than an 80 percent reduction in geographic range by the end of the century, according to a new University of California, Berkeley, study. Because e...

Golfers and golf courses benefit from the use of native grasses in roughs

Some golfers may prefer a well-manicured golf course, highly-maintained with very green, very short grass that's easy to play off of.
