`Secret Life of Scientists`: What do they do when not in the lab? A juggling climate scientist, a back-flipping engineer, 'leech man,' and a physics student who plays in the cult band Harry and the Potters star in a new Web-only series that delves into the quirky secret lives of scientists and engineers. USATODAYCell therapy to help transplants Australian scientists have found that cellular therapy can treat a deadly complication that occurs after half of all bone marrow transplants. Science AlertUsing Systems Biology to Study Influenza Systems biology is the study of how individual molecular components in a cell interact with each other to create active biological systems. This 'grand scale' study of things generates information on the relationships between the structure and function of macromolecules (such as proteins), reaction dynamics (specific activity), and mechanisms for controlling reaction rates. These days, much of the information is built into models so that when new proteins with similar sequences are encountered, their systemic roles can be predicted. The information obtained about the immune system, or viral and bacterial systems, can be used to produce better vaccines. For example, scientists at the Institute for Systems Biology are using what they have learned about the systems of the influenza virus to determine what makes one strain more potent than another. Some of this has to do with polymorphisms of proteins on the viral outer envelope, and their tolerance for remaining functional upon mutation. AboutNew Species of Giant Spider Discovered Small Male (red) Golden Orb Weaver Spider on FemaleImage: M. Kuntner Giant golden orb weaver spiders are well-known for their web spinning capabilities. They produce the largest orb webs which can be as large as 3 feet in diameter. Researchers have announced the discovery of a new species of giant golden orb weavers found in Africa and Madagascar. This species, Nephila komaci, is very rare and it is feared that the spiders are an endangered species. An interesting fact about giant golden orb weavers is that only the females of the species are enormous. Females have a body length of about 1.5 inches with a leg span between 4 to 5 inches. The researchers believe that the females have evolved over time in their tropical environment to become larger as a result of natural selection. The males however did not experience this same size change and remained at least five times smaller than the females.

Scientists demonstrated that women are better than men at processing auditory, visual and audiovisual emotions. Science dailyINDIA: Controversy Rages over Genetically Modified 'Brinjal' NEW DELHI, Oct 22 (IPS) - Scientists and activists say that but for the fact that the 'brinjal', also called 'eggplant' or 'aubergine', is native to India and a favourite on the table, the decision to allow commercial release of its genetically modified (GM) variety may have gone unremarked. IPSAllegations of spying and links to terrorism land scientists in hot water Two researchers, one a physicist working on the Large Hadron Collider in Europe and the other a space scientist with leading roles on several lunar satellite missions, have run afoul of the authorities this month for alleged terrorist links and attempted spying, respectively.

ABC.net.au`Eighth wonder` Ida not related to humans, claim scientists US palaeontologists dismiss initial claims about the 47million-year-old fossil found in Germany's Messel PitHer arrival was announced with unrestrained razzmatazz. She was the 'eighth wonder of the world', 'our Mona Lisa' and an evolutionary 'Rosetta Stone', according to the researchers who unveiled her.The female in question was Ida, a 47million-year-old primate, whose exquisitely preserved fossil was touted as the remains of our earliest human ancestor. She was, they said, the 'link' between us and the rest of the animal kingdom.Or maybe not. Writing in the journal, Nature, a team of palaeontologists from New York claim that Ida is not related to humans at all. Instead, they conclude, the $1m fossil looks more like a small lemur or maybe a loris.The challenge is being seen as the opening salvo in what is shaping up to be a hearty academic slugging match. At stake is not only the significance of one of the most extraordinary fossils unearthed, but the reputations of some of the world' Guardian1 2 3 4 |
