(PhysOrg.com) -- Climate projections for the next 50 to 100 years forecast increasingly frequent severe droughts and heat waves across the American Southwest, sinking available water levels even as rising mercury drives up demand for it. http://www.physorg.com/news178913021.html Space & Earth Tue, 01 Dec 2009 18:04:13 EST news178913021 A huge amount of scientific data have been accumulated by the CE-1 lunar orbiter. Using laser altimeter data, Jinsong Ping and Qian Huang et al obtained improved 3D lunar topography, and based on this, they had made new discoveries (such as impact basins and volcanic deposit highlands) of some ancient topographic characteristics on the lunar surface. Chao Chen and Qing Liang et al found the South Pole-Aitken (SPA) basin as the biggest mascon on the moon and put forward a fault structure hypothesis for the Apenninue Mountain, which is significant for the study of the origin and evolution of the moon. http://www.physorg.com/news178867605.html Space & Earth Tue, 01 Dec 2009 05:40:02 EST news178867605 PIC=32536:left]Increasing temperatures at high altitudes are fueling the post-1950 growth spurt seen in bristlecone pines, the world's oldest trees, according to new research. http://www.physorg.com/news177608541.html Space & Earth Mon, 16 Nov 2009 16:30:01 EST news177608541 (PhysOrg.com) -- In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial. http://www.physorg.com/news176395329.html Space & Earth Mon, 02 Nov 2009 14:43:38 EST news176395329 An international group of scientists aboard the Deep-Sea Drilling Vessel CHIKYU, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for the Integrated Ocean Drilling Program (IODP), return from a 40-day scientific expedition off the shore of the Kii Peninsula, Japan on Oct. 10, 2009.

St-Laurent. They were headed through the Northwest Passage, but instead of opening shipping lanes in the ice, they had gathered to open up new lines of thinking on Arctic science. http://www.physorg.com/news171037289.html Space & Earth Tue, 01 Sep 2009 15:40:03 EST news171037289 The Atlantic Ocean's second Tropical Depression has been on shaky ground since it formed early in the week of August 11. It meandered westward from the African coast and maintained its tropical depression status until weakening to a remnant low. Now it has the potential to come back. In addition to Tropical Depression 2, there are three other areas forecasters are watching in the Atlantic Basin. Residents of Florida should particularly be watchful as there's a potential for tropical development on both the east and west coasts this weekend. http://www.physorg.com/news169492435.html Space & Earth Fri, 14 Aug 2009 18:14:52 EST news169492435 Geologists of the University of Granada, Spain, have described for the first time ever the biological mechanism that explains how calcareous red algae grow on rocky substrates. http://www.physorg.com/news168352779.html Biology Mon, 03 Aug 2009 13:40:03 EST news168352779 Mounting evidence that human activity is changing the world's oceans in profound and damaging ways is outlined in a new scientific discussion paper released today. http://www.physorg.com/news168085384.html Space & Earth Wed, 29 Jul 2009 11:24:40 EST news168085384 The Water Science and Technology Board, (WTSB), Division on Earth and Life Sciences of the National Research Council has released for publication its study for improving water quality in the Mississippi River Basin and Northern Gulf of Mexico.

A team from the Pyrenean Institute of Ecology (CSIC) has studied rainfall data from 1950 to 2006 and the climate projections for coming decades, showing that less rain will fall in future over the Iberian Peninsula. However, precipitation will continue to be more frequent in winter than in spring-summer. http://www.physorg.com/news167552453.html Space & Earth Thu, 23 Jul 2009 07:40:02 EST news167552453 As many as 4,550 of the more than 50,000 plant species in the Amazon will likely disappear because of land-use changes and habitat loss within the next 40 years, according to a new study by two Wake Forest University researchers. http://www.physorg.com/news166376723.html Biology Thu, 09 Jul 2009 16:45:55 EST news166376723 According to new research published online in the Proceedings of the Royal Society B (Biological Sciences) on July 1, 2009, a new fossil primate from Myanmar (previously known as Burma) suggests that the common ancestor of humans, monkeys and apes evolved from primates in Asia, not Africa as many researchers believe. http://www.physorg.com/news165643933.html Other Sciences Wed, 01 Jul 2009 05:12:49 EST news165643933 (PhysOrg.com) -- There are very few places in the world where dynamic activity taking place beneath Earth's surface goes undetected. http://www.physorg.com/news162573232.html Space & Earth Tue, 26 May 2009 16:15:02 EST news162573232 Aggressive, vengeful behavior of individuals in some South American groups has been considered the means for men to obtain more wives and more children, but an international team of anthropologists working in Ecuador among the Waorani show that sometimes the macho guy does not do better. http://www.physorg.com/news161281260.html Other Sciences Mon, 11 May 2009 17:21:20 EST news161281260 A previously unknown, large impact basin has been discovered by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during its second flyby of Mercury in October 2008.
