Mon 2 Nov 2009 Discovery May Lead To Precision Engineering Of Superconducting Thin Films For Electronic Devices. Using precision techniques for making superconducting thin films layer-by-layer, physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have identified a single layer responsible for one such material's ability to become superconducting, i.e., carry electrical current with no energy loss. The technique could be used to engineer ultrathin films with "tunable" superconductivity for higher-efficiency electronic devices. more

Sun 25 Oct 2009 Fruit Fly Pest Identified In Grapes. A newly recognized pest in Oregon continues to concern fruit growers and researchers with the recent discovery of a Spotted Wing Drosophila fly in a sample of Willamette Valley wine grapes.
Signs of possible infestation include: Spotted Drosophila flies with a pale black spot at the leading edge of the wing (only the male flies of this species have this marking), Small puncture wound on hanging fruit, where female drilled in to lay her eggs, Soft fruit on plant, starting at puncture scar. Secondary decay can establish at this point, and Small pale maggots in intact fruit on the plant.more

Thu 22 Oct 2009 Microsoft launched Windows 7 OS today. Microsoft made the near-final release candidate version available last month. Shortly after its release, Microsoft finally confirmed that it was aiming Windows 7 for a holiday 2009 release, something that was widely anticipated, but not confirmed by Redmond-based MS.

Wed 21 Oct 2009 Physicists Develop Multifunctional Storage Device For Light. Light is intangible and, in addition, it travels at great velocity. Nevertheless, it can be confined to a very small space by controllably inserting light into a microscopic container surrounded by reflective walls. The light will then be stored by continuous reflections and cannot escape. In the scientific domain, such a small reflective microcavity is termed a microresonator. These microresonators find applications in all areas where the interaction between light and matter shall be enhanced and studied in a controlled manner. An important area of usage is, for example, the laser diode, which has revolutionized telecommunications and optical data storage in the past few decades. more

Tue 20 Oct 2009 Canadian chemists have taken the science behind a specific type of fuel cell towards a higher level of design. They have discovered a new material that allows a PEM fuel cell, known as a polymer electrolyte membrane fuel cell, to work at a higher temperature. This discovery is extremely important in terms of increasing the efficiency and decreasing the cost of PEM fuel cells.more

Thu 8 Oct 2009 The 2009 Nobel Prize in Chemistry awards Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath for having showed what the ribosome looks like and how it functions at the atomic level. All three have used a method called X-ray crystallography to map the position for each and every one of the hundreds of thousands of atoms that make up the ribosome. Their studies covered one of life's core processes: the ribosome's translation of DNA information into life. Ribosomes produce proteins, which in turn control the chemistry in all living organisms. As ribosomes are crucial to life, they are also a major target for new antibiotics. more
