Nepeta is a genus of about 250 species of flowering plants in the family Lamiaceae. The members of this group are known as catnips or catmints.

The genus is native to Europe, Asia and Africa, with the highest species diversity in the Mediterranean region east to China. Most of the species are herbaceous perennial plants, but some are annuals. They have sturdy stems with opposite heart-shaped, green to greyish-green leaves. The flowers are white, blue, pink or lilac and occur in several clusters toward the tip of the stems.

Medicinal uses

Due to the fact that catnip promotes sweating when used as an herbal tea, it was used for the treatment of nervousness, colds, influenza, and fevers during the Middle Ages. Catnip has also been alleged to aid with flatulence, diarrhea, colic, and other childhood diseases, as well as preventing miscarriages, premature births, and morning sickness. It is also sometimes used as an enema (Plants).

Clean water should be recognized as a human right. At the March 2009 United Nations meetings coinciding with the World Water Forum, a declaration that would recognize water as a basic human right was defeated. In this month's Editorial, the PLoS Medicine Editors argue that access to clean water should be declared a basic human right for three reasons. First, access to clean water can substantially reduce the global burden of disease caused by water-borne infections. Second, the privatization of water—as witnessed in Bolivia, Ghana, and other countries—has not effectively served the poor, who suffer the most from lack of access to clean water. Third, the prospect of global water scarcity—exacerbated by climate change, industrial pollution, and population growth—means that no country is immune to a water crisis.Image Credit: Rudhach at flickr.com

(University of California - San Francisco) University of California - San Francisco researchers have identified a new "feed-forward" pathway linking estrogen receptors in the membrane of the uterus to a process that increases local estrogen levels and promotes cell growth.
'Genetic arms race' between bacteria, viruses subject of stimulus grant

(Michigan State University) The oceans teem with microscopic bacteria that produce much of Earth's oxygen as they absorb carbon dioxide greenhouse gas. But fast-mutating viruses also populate the seas, attacking marine bacteria in an ages-old evolutionary arms race. A Michigan State University researcher will probe that ancient dynamic against the backdrop of environmental and climate change, and the pivotal role played by aquatic bacteria in maintaining the Earth's biological balance.
