Urban Ecology: Taking Measure Of The Coming Megacity's Impact![]() If you are reading this, chances are that you live in a city - one, perhaps, on its way to becoming a megacity with a population that exceeds 10 million or more. If not, you and most of the world's population soon will be, according to global population demographics projections. What shape could these future cities take and how will their populations meet environmental and resource challen ... more Natural Ocean Thermostat May Protect Some Coral Reefs ![]() Natural processes may prevent oceans from warming beyond a certain point, helping protect some coral reefs from the impacts of climate change, new research finds. The study, by scientists at the National Center for Atmospheric Research (NCAR) and Australian Institute of Marine Science (AIMS), finds evidence that an ocean "thermostat" appears to be helping to regulate sea-surface temperatures in ... more Wind Patterns Could Mask Effects Of Global Warming In Ocean ![]() Scientists at the University of Liverpool have found that natural variability in the earth's atmosphere could be masking the overall effect of global warming in the North Atlantic Ocean. Scientists have previously found that surface temperatures around the globe have risen over the last 30 years in accord with global warming. New data, however, shows that heat stored in the North Atlantic ... more Study: Nitrogen pollution ups plant growth ![]() U.S. ecologists have found excess nitrogen in tropical forests boosts plant growth by an average of 20 percent. University of California-Irvine scientists said their finding counters the belief that such forests wouldn't respond to nitrogen pollution. The researchers said faster plant growth means the tropics will take in more carbon dioxide than previously thought, although long ... more Australia has 'shocking' evidence of Japan's whaling: minister ![]() Australia has "shocking" photographic evidence to back an international legal bid to stop Japanese whaling in Antarctic waters, the government said Thursday. One picture showing a mother whale and her calf being dragged aboard a Japanese whaler after being harpooned was described as sickening by Environment Minister Peter Garrett. "I guess when I saw the photos I just felt a bit of a sic ... more |

![]() ![]() Scientists from the University of Bonn are researching which plants giant dinosaurs could have lived off more than 100 million years ago. They want to find out how the dinosaurs were able to become as large as they did. In actual fact such gigantic animals should not have existed. The results of the research have now been published in the journal 'Proceedings of the Royal Society B'. Take ... more Emory Researcher Finds Crayfish Fossils Provide Missing Evolutionary Link ![]() Crayfish body fossils and burrows discovered in Victoria, Australia, have provided the first physical evidence that crayfish existed on the continent as far back as the Mesozoic Era, says Emory University paleontologist Anthony Martin, who headed up a study on the finds. "Studying the fossil burrows gives us a glimpse into the ecology of southern Australia about 115 million years ago, when ... more Ecuador volcano blows its top, forces 1,450 from homes ![]() Ecuador's Tungurahua volcano exploded into action Wednesday, spewing red-hot lava, rocks and a 10-kilometer (six-mile) high plume of ash that forced 1,450 people from their homes, officials said. "The eruption is going on right now and continues to generate pyroclastic flows" of red-hot gas, ash and rocks down the volcano's western flank, Geophysical Institute director Hugo Yepez told report ... more Converting land for biofuel worsens global warming: study ![]() Clearing raw land to produce biofuels actually contributes to global warming by emitting large amounts of greenhouse gases into the atmosphere, researchers warned Thursday. Carbon dioxide emissions from new croplands carved into rainforests, savannas, wetlands or grasslands would easily surpass the overall amount of CO2 emissions reduced through the use of biofuels, according to an expert report ... more U.S. OKs uranium search near Grand Canyon ![]() The U.S. Forest Service has approved a permit allowing a mining company to look for uranium near Grand Canyon National Park. Officials in Coconino County, Ariz., voted Tuesday to try to block any potential uranium mines immediately north and south of the national park, The New York Times reported. The newspaper said the discovery of rich uranium deposits by British mining company Vane M ... more |

![]() ![]() Taking a page out of a science fiction story, researchers from the Woods Hole Oceanographic Institution (WHOI) and Webb Research Corporation (Falmouth, Mass.) have successfully flown the first environmentally powered robotic vehicle through the ocean. The new robotic "glider" harvests heat energy from the ocean to propel itself across thousands of kilometers of water. In December 2007, a r ... more Nation's Top Divorce Lawyers Note Dramatic Rise In Electronic Evidence ![]() A resounding 88% of the nation's top divorce attorneys say they have seen an increase in the number of cases using electronic data as evidence during the past five years, according to a recent survey of the American Academy of Matrimonial Lawyers (AAML). E-mail takes the lead as the most commonly used form of technological evidence, with 82% citing it as the main source. Interestingly, the surve ... more CalAmp Licenses Patents For Vehicle Location Technology To SKYWATCH GPS ![]() CalAmp announced that it has entered into a patent license agreement with SKYWATCH GPS for use of CalAmp's U.S. Patent Nos. 6,025,774 and 6,249,217 B1. The patents relate to a vehicle location system that enables automobile finance companies to locate and repossess vehicles serving as collateral on loans that go into default. CalAmp acquired these patents as part of its acquisition of the ... more Broadcom Showcases Next Gen Mobile Devices At 2008 Mobile World Congress ![]() Broadcom will demonstrate its innovative and leading portfolio of complete system-on-a-chip (SoC) solutions for mobile devices at the 2008 Mobile World Congress trade show in Barcelona, Spain, from February 11th through February 14th. Broadcom mobile and wireless technologies enable manufacturers to develop leading-edge mobile devices and end-to-end wireless connectivity solutions for the home, ... more NXP Fuels Rise Of Mobile Location-Based Services ![]() Quickly following the January 23rd closing of its acquisition of GPS technology provider GloNav, NXP Semiconductors announced its first single-chip, Assisted-GPS (A-GPS) solution, designed for use in both mobile phones and standalone personal navigation devices (PNDs). Built on an advanced architecture, NXP's GNS7560 is the industry's smallest, lowest power, lowest system cost GPS solution. ... more
