Biologists determined that short-term, seasonal exposure to pesticides in rivers and basins may limit the growth and size of wild salmon populations. In addition to the widespread deterioration of salmon habitats, these findings suggest that exposure to commonly used pesticides may further inhibit the recovery of threatened or endangered populations. http://www.physorg.com/news180182664.html Biology Wed, 16 Dec 2009 10:45:54 EST news180182664 NASA researchers studying urban landscapes have found that the intensity of the "heat island" created by a city depends on the ecosystem it replaced and on the regional climate. Urban areas developed in arid and semi-arid regions show far less heating compared with the surrounding countryside than cities built amid forested and temperate climates. http://www.physorg.com/news180120409.html Space & Earth Tue, 15 Dec 2009 18:30:02 EST news180120409 The Honda Personal-Neo Urban Transport (P-NUT) design study model demonstrates a futuristic concept for an ultra-compact and sophisticated city coupe, American Honda Motor announced at the 2009 Los Angeles Auto Show. http://www.physorg.com/news179081899.html Technology Thu, 03 Dec 2009 17:10:01 EST news179081899 San Francisco and Amsterdam set an online stage for an environmental rivalry regarding which city is more nature-friendly. http://www.physorg.com/news178952100.html Space & Earth Wed, 02 Dec 2009 04:55:55 EST news178952100 Sewer overflows are a nasty business, posing dangers to human health and the environment.

Air travel is one of the ways that individuals contribute to an increase in pollution and to global climate change. Some believe that purchasing carbon offsets can help decrease their impact on the planet by contributing money to projects that reduce carbon dioxide, thereby offseting their own activities. In an effort to make this process easier for those traveling by airplane, the San Francisco airport now has kiosks at which travelers can buy offsets before they board. http://www.physorg.com/news172763698.html Space & Earth Mon, 21 Sep 2009 15:14:31 EST news172763698 Via Tiburtina is the name of the ancient road that is still in use, connecting Rome with the town of Tivoli.

Autonomous vehicle navigation, as the technology is known, may make life more convenient if it allows people to kick back and enjoy a good book or movie while their cars guide themselves through rush-hour traffic. But what happens if it starts to rain or if traffic suddenly picks up? If the technology is to work at all, it will have to be completely safe on all roads, under all speeds, and in all weather. Therein lies the challenge: if cars and trucks are to drive autonomously, they will need futuristic sensors and advanced computing capabilities to respond to ever-changing road conditions. http://www.physorg.com/news162573964.html Technology Tue, 26 May 2009 16:26:30 EST news162573964 A novel species of bacteria with cholesterol-busting properties has been discovered by scientists at the Universidad Complutense de Madrid, Spain.
