Mon 4 Jan 2010 Using Modern Sequencing Techniques to Study Ancient Humans. DNA that is left in the remains of long-dead plants, animals, or humans allows a direct look into the history of evolution. So far, studies of this kind on ancestral members of our own species have been hampered by scientists' inability to distinguish the ancient DNA from modern-day human DNA contamination. It is possible to directly analyze DNA from a member of our own species who lived around 30,000 years ago. more

Sun 27 Dec 2009 A Korean consortium has won the $20 billion nuclear power contract with the United Arab Emirates proving Korea's global leadership status in nuclear industry. It is the first time that a Korean consortium has won a contract to build nuclear power facilities in a foreign country. Korea thus has become the world's sixth exporter of nuclear power facilities after the United States, France, Canada, Russia and Japan. The Korean consortium, which includes the Korea Electric Power Corp., Hyundai Engineering and Construction, Samsung C&T Corp. and Doosan Heavy Industries, won the order to build four 1400 MW light water nuclear power reactors in Sila, 330 Km west of Abu Dhabi, the first of which to go critical by 2017. The UAE, the world's third-largest oil exporter, is planning to meet an expected need for an additional 40 gegawatts of power by 2020. more

Sun 20 Dec 2009 Looking for the Heartbeat of Cellular Networks. Our cells' molecules form an intricate network of interactions. Today's techniques, however, can only be used to measure individual molecular reactions outside the cells. Since molecular concentrations are much higher in cells than in the laboratory, scientists suspect that the kinetics of molecular reactions in living cells differ substantially from external probes. more

Mon 14 Dec 2009 Absorbing Hydrogen Fluoride Gas to Enhance Crystal Growth. Two scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have developed a method to control the buildup of hydrogen fluoride gas during the growth of precision crystals needed for applications such as superconductors, optical devices, and microelectronics. The invention, by Vyacheslav Solovyov and Harold Wiesmann and recently awarded U.S. Patent number 7,622,426, could lead to more efficient production and improved performance of these materials.more

Wed 2 Dec 2009 First Live Targeting of Tumors with RNA-Based Technology. Finding and treating a tumor without disturbing normal tissue presents challenges. Researchers at Duke University Medical Center have devised a way they might deliver the right therapy directly to tumors using special molecules, called aptamers, which specifically bind to living tumor tissue. They screened a large pool of aptamers in a rodent with liver cancer until they found the best molecule to bind to a tumor protein. more

Thu 19 Nov 2009 In Touch with Molecules. The performance of modern electronics increases steadily on a fast pace thanks to the ongoing miniaturization of the utilized components. However, severe problems arise due to quantum-mechanical phenomena when conventional structures are simply made smaller and reach the nanometer scale. Therefore current research focuses on the so-called bottom-up approach: the engineering of functional structures with the smallest possible building blocks – single atoms and molecules. For the first time a collaboration of researchers across Europe now achieved to investigate the electrical behaviour of only two C60-molecules touching each other. The molecule which is shaped like a football was discovered in 1985 and since then has attracted tremendous attention by researchers all over the world due to its unique chemistry and potential technological applications in nanotechnology, materials science and electronics. more
