The technology is also being rapidly taken up by the UK building trade who are delighted to have fingerprint technology which can cope with the often worn and ravaged builders' thumbprints. http://chinese.eurekalert.org/en/pub_releases/2009-11/uow-ftb110409.php Wed, 04 Nov 2009 00:00:00 EST In contrast with some common perceptions regarding 2009 influenza A (H1N1) infections, an examination of cases in California indicates that hospitalization and death can occur at all ages, and about 30 percent of hospitalized cases have been severe enough to require treatment in an intensive care unit, according to a study in the Nov. 4 issue of JAMA. http://chinese.eurekalert.org/en/pub_releases/2009-11/jaaj-roh103009.php Wed, 04 Nov 2009 00:00:00 EST The highlights of the PNAS tipsheet for November 2-6: The disappearing glaciers of Kilimanjaro; Designer cells may help protect the body from itself; Genetic component of metabolic syndrome; Cooperative social behavior in man-eating lions; Improving spinal cord injury recovery; Sleep likely consolidates observational learning. http://chinese.eurekalert.org/en/pub_releases/2009-11/potn-103009.php Tue, 03 Nov 2009 00:00:00 EST An assessment published in the November issue of BioScience finds some positive trends among indicators of biodiversity loss in China, notably an increase in forests and recent improvements in marine ecosystems, although other indicators, such as the rate of discovery of invasive species, are worsening. Many animals are under growing threat. http://chinese.eurekalert.org/en/pub_releases/2009-11/aiob-102809.php Tue, 03 Nov 2009 00:00:00 EST A goal of a 50% reduction in global greenhouse gases emissions by 2050, with an 80% reduction by developed countries (hereafter referred to as the G8 Goal), was proposed at the G8 Summit held in L'Aquila, Italy, in July 2009. A study analyze the scientific and political implications of the G8 Goal and its equity and feasibility was published on the October issue of Science in China Series D: Earth Sciences. http://chinese.eurekalert.org/en/pub_releases/2009-11/sicp-sao102909.php Sun, 01 Nov 2009 00:00:00 EDT
