Humans Have Caused Profound Changes In Caribbean Coral Reefs![]() Coral reefs in the Caribbean have suffered significant changes due to the proximal effects of a growing human population, reports a study published in the Proceedings of the Royal Society of London, B. "It is well acknowledged that coral reefs are declining worldwide but the driving forces remain hotly debated," said author Camilo Mora at Dalhousie University, Halifax, Canada. "In the Cari ... more Freeze-dried tendon implants hold promise ![]() U.S. researchers said donated freeze-dried tendon grafts loaded with gene therapy may soon be used to repair injured tendons. A report, published in the journal Molecular Therapy, said the graft technique may provide the first effective framework around which flexor tendon tissue can reorganize as it heals. University of Rochester Medical Center researchers found donated, freeze- ... more Sub-Saharan Africa: The Population Emergency ![]() Sub-Saharan Africa has been experiencing phenomenal population growth since the beginning of the 20th Century, following several centuries of population stagnation attributable to the slave trade and colonization. The region's population in fact increased from 100 million in 1900 to 770 million in 2005. The latest United Nations projections, published in March 2007, envisaged a figure of 1.5 to ... more Cold snap kills eight in Iran ![]() At least eight people froze to death in the heaviest snowfalls to have hit Iran in years, with several areas brought to a virtual standstill and 20 towns suffering cuts in gas supplies, officials said on Tuesday. The snowfalls, said to be the worst in some 40 years, have forced all schools and government offices to close in Tehran and other regions in northern Iran over the last two days. Th ... more Building boom drives rapid AIDS spread in Indonesia: ADB ![]() Indonesia's construction boom is driving an "exponential" rise in HIV-AIDS infections as migrant workers are more likely to engage in high-risk sex, the Asian Development Bank warned Tuesday.

The German federation for renewable energy (BEE) warned however that further progress was likely to be hampered by falling investment in renewable energy sources. A total of 9.1 percent of the energy for Europe's biggest ... more China to contribute 1.4 billion dollars to ITER ![]() China will contribute 1.4 billion dollars to an international nuclear fusion project that aims to emulate the power of the sun to provide limitless clean energy, state press said Tuesday. The 10 billion yuan (1.4 billion dollars) would make up about 10 percent of the cost of the International Thermonuclear Experimental Reactor (ITER) to be built in France and expected to go online by 2016, t ... more San Diego Non-Profit HRC Helps California Adapt To Climate Change ![]() A recently completed river-flow and reservoir management demonstration project shows how a new technology can help California generate more electricity and save water. The Integrated Forecast and Management (INFORM) system has the potential to boost hydroelectric production by up to 20% while increasing water supplies by up to 50%. INFORM was developed by the Hydrologic Research Center (HR ... more Encore Energy Systems To Provide Grey Water Geothermal Utility To Australia Wastewater Treatment Plants ![]() Encore Energy Systems has announced plans to make their patented grey water geothermal solutions available to the wastewater treatment industry "Down Under." Wastewater treatment plants (WWTP) are expanding to meet demand the world over, and grey water reuse is becoming a major player in the renewable energy sector. Grey water is a valuable asset for many communities throughout the world a ... more Switchgrass shows biofuel potential ![]() Nebraska researchers said switchgrass yields significantly more energy than is consumed in its production and conversion into cellulosic ethanol. A five-year study involving farms in Nebraska, North Dakota and South Dakota examined the net energy output, greenhouse gas emissions, biomass yields, agricultural inputs and estimated cellulosic ethanol production from switchgrass grown and m ... more |

This major challenge to conventional thinking is the surprising finding of a study published in the Proceedings of the US National Academy of Sciences by Dr Alan Grainger, Senior Lecturer in Geography and one of the world's leading experts on tropical deforesta ... more Electric Sand Findings Could Lead To Better Climate Models ![]() Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. The other culprit is electricity. By taking both factors into account, researchers at the University of Michigan have developed a new model that matches real-world measurements of "saltation" better than the decades-old classical theory. Saltation is the process of wind ... more Researchers ask: Is China the sleeping giant of biotech ![]() China's biotech sector accounts for just a sliver of its pharmaceutical industry and operates under the cloud of a massive review of licenses issued under a regulator executed last year for accepting bribes. Even so, experts say, Chinese purveyors of genetically engineered drugs and vaccines -- targeting everything from cancer to Alzheimer's -- are growing at a frenzied pace and are likely t ... more New unrest as government vows 'radical' solution to Naples rubbish crisis ![]() re> New unrest erupted outside Naples /pre> overnight, the ANSA news agency reported Tuesday, as Italy's centre-left government pledged a speedy, "radical" solution to a Mafia-linked rubbish disposal crisis in the region.
