Two new minute spider species have been discovered from the Sichuan and Chongqing, China. The tiny new spiders are both less than 2 mm in length, with Trogloneta yuensis being as little as 1.01 mm and Mysmena wawuensis measured to be the even tinier 0.75 mm, which classes it among the smallest spiders known. The two species described in the open access journal Zookeys both have a bizarre body shape with disproportionately big spherical posterior body. http://phys.org/news288434823.html Biology Wed, 22 May 2013 09:49:11 EST news288434823 Two annually dated ice cores drawn from the tropical Peruvian Andes reveal Earth's tropical climate history in unprecedented detail—year by year, for nearly 1,800 years. http://phys.org/news284300318.html Space & Earth Thu, 04 Apr 2013 14:00:05 EST news284300318 Biologists at the University of California, San Diego have succeeded in engineering algae to produce potential candidates for a vaccine that would prevent transmission of the parasite that causes malaria, an achievement that could pave the way for the development of an inexpensive way to protect billions of people from one of the world's most prevalent and debilitating diseases. Initial proof-of-principle experiments suggest that such a vaccine could prevent malaria transmission. http://phys.org/news256404934.html Biology Wed, 16 May 2012 17:00:01 EST news256404934 (Phys.org) -- The area of the globe covered by wetlands (swamps, marshes, lakes, etc.) has dropped by 6% in fifteen years. This decline is particularly severe in tropical and subtropical regions, and in areas that have experienced the largest increases in population in recent decades. These are the conclusions of a study conducted by CNRS and IRD researchers from the Laboratoire d'étude du rayonnement et de la matière en astrophysique, Laboratoire d'études en géophysique et oceanography spatiales and the start-up Estellus. To obtain these results, the scientists performed the first worldwide mapping of the wetlands and their temporal dynamics, for the years 1993 to 2007. This study, which has just been published in the journal Geophysical Research Letters, emphasizes the impact of population pressure on water cycles. http://phys.org/news256206742.html Space & Earth Mon, 14 May 2012 09:32:48 EST news256206742
