Fertilizer chemicals may pose a bigger hazard to the environment — specifically to creatures that live in water — than originally foreseen, according to new research from North Carolina State University toxicologists.

In its 4.5 billion years, Earth has evolved from its hot, violent birth to the celebrated watery blue planet that stands out in pictures from space. But in a new book, two noted astrobiologists say the planet already has begun the long process of devolving into a burned-out cinder, eventually to be swallowed by the sun.
Global warming is having a significant impact on hundreds of plant and animal species around the world — although the most dramatic effects may not be felt for decades, according to a new study in the journal Nature. “Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner,” said Terry L. Root, a senior fellow with Stanford’s Institute for International Studies (IIS) and lead author of the Jan. 2 Nature study. “Clearly, if such ecological changes are now being detected when the globe has warmed by an estimated average of only 1 degree F (0.6 C) over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F (6 C),” Root concluded.
Viagra may help to save many species of animals and plants that are now endangered due to the demand for animal sexual potency products, according to new research from the University of New South Wales and the University of Alaska. The research suggests that the availability of viagra is having an impact on trade in some of the products, which are used in traditional Chinese medicine to treat impotence, including body parts from seals, deer, green turtles, sea cucumbers, pipefishes, sea horses and geckos.
