Sponges and other marine animals which cannot move around might seem to be defenceless against predators. Yet nothing is further from the truth. These animals produce biologically active chemical substances which provide them with an effective defence against their enemies. http://www.physorg.com/news177947175.html Biology Fri, 20 Nov 2009 14:10:02 EST news177947175 (PhysOrg.com) -- Not just birds, but also a few species of bats face a long journey every year. Researchers at Princeton University in the U.S. and at the Max Planck Institute for Ornithology in Radolfzell, Germany studied the migratory behaviour of the largest extant family of bats, the so-called "Vespertilionidae" with the help of mathematical models. They discovered that the migration over short as well as long distances of various kinds of bats evolved independently within the family. http://www.physorg.com/news177948336.html Biology Fri, 20 Nov 2009 14:06:17 EST news177948336 A US judge set February 18 for a hearing on the revised legal settlement between Google and US authors and publishers that would allow the Internet giant to scan and sell millions of books online. http://www.physorg.com/news177945750.html Technology Fri, 20 Nov 2009 13:50:01 EST news177945750 The World Health Organisation said Friday that a mutation had been found in samples of the swine flu virus taken following the first two deaths from the pandemic in Norway. http://www.physorg.com/news177945959.html Medicine & Health Fri, 20 Nov 2009 13:26:27 EST news177945959 Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine researchers have identified a gene that may play a pivotal role in two processes that are essential for tumor development, growth and progression to metastasis. Scientists hope the finding could lead to an effective therapy to target and inhibit the expression of this gene resulting in inhibition of cancer growth. http://www.physorg.com/news177945339.html Medicine & Health Fri, 20 Nov 2009 13:16:30 EST news177945339 A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. Now, in a study appearing in this week's Journal of Biological Chemistry, researchers in Italy have reconstructed one of the earliest evolutionary steps yet: generating long chains of RNA from individual subunits using nothing but warm water. http://www.physorg.com/news177945116.html Chemistry Fri, 20 Nov 2009 13:12:36 EST news177945116 (PhysOrg.com) -- Not too long ago, it seemed that ethanol production was the wave of the future. The use of trash, wood chips or different types of plants -- usually grass or corn -- to make ethanol was considered a way to help reduce reliance on foreign oil. However, investor interest in the process cooled, especially since it turned out that some materials were not terribly efficient when it came to producing ethanol. However, wood chips are once again being considered in the quest to create an industry based around cellulosic ethanol. http://www.physorg.com/news177942392.html Chemistry Fri, 20 Nov 2009 12:27:35 EST news177942392 (PhysOrg.com) -- On the surface, English, Japanese, and Kinande, a member of the Bantu family of languages spoken in the Democratic Republic of Congo, have little in common. It is not just that the vocabularies of these three languages are vastly different; many of their rules of grammar diverge too. http://www.physorg.com/news177940651.html Other Sciences Fri, 20 Nov 2009 11:58:56 EST news177940651 Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing.
