Researchers find 24 species believed new to science in Suriname rainforest

...bian life. Among the 24 species believed new to science are an Atelopus frog with brilliant purple markings, four Eleutherodactylus frog species, six species of fish, 12 dung beetles and an ant species. The scientists also found 27 species endemic to the Guayana Shield region comprising Suriname and neigh...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

The science has long been clear that smoking causes cancer, but new research shows that children could inherit genetic damage from a father who smokes. Canadian researchers have demonstrated in mice that smoking can cause changes in the DNA sequence of sperm ...

Dirty snow may warm Arctic as much as greenhouse gases

...harlie Zender, associate professor of Earth system science at UCI and co-author of the study. “Dark soot can heat up quickly. It’s like placing tiny toaster ovens into the snow pack.” The study appears this week in the Journal of Geophysical Research. Dirty snow has had a significant impact on climate ...

New study finds genetically engineered crops could play a role in sustainable agriculture

... and the first of its kind to evaluate the current science surrounding genetically modified crops. The results are significant for how we think about technology and the future of sustainable agriculture,” said Peter Kareiva, chief scientist of The Nature Conservancy. According to lead author, Michele Ma...

The mouflons of the Kerguelen archipelago

...lated places on Earth, house a military base and a science station. In 1957, the local authorities decided to offer residents the opportunity to hunt mouflons (a type of wild sheep). A pair of Corsican mouflons was imported from the Vincennes Zoo in Paris. Initially, the mouflon population grew exponentially...

Scientists close in on missing carbon sink

...For years, one of the biggest mysteries in climate science has been the question of what ultimately happens to the carbon emitted by motor vehicles, factories, deforestation, and other sources. Of the approximately 8 billion tons of carbon emitted each year, about 40 percent accumulates in the atmosphere and...

Modified mushrooms may yield human drugs

...maine, who holds the John B. Swayne Chair in spawn science and professor of plant pathology at Penn State. "Mushrooms could make the ideal vehicle for the manufacture of biopharmaceuticals to treat a broad array of human illnesses. But nobody has been able to come up with a feasible way of doing that." ...

New designer lipid-like peptide with lipid nanostructures for drug delivery systems

... findings not only help us to understand the basic science of how lipid-like peptides interact with lipid molecules, but also may provide new strategies for the encapsulation and the delivery of biological active materials. They detailed their findings in the report on the impact of integrating short surfac...

Lessons from the orangutans: Upright walking may have begun in the trees

...ournal Science , published by AAAS, the nonprofit science society. Upright walking, or bipedalism, has long been considered a defining feature of humans and our closest ancestors. One of the most popular explanations, known as the savannah hypothesis, suggests that the ancestors to chimps, gorillas and h...
