Zinc oxide gives green shine to new photoconductors
Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manufacture of very powerful photodetectors needs to be improved before they can qualify for solid green status. view more (2009-03-19)
A First in Integrated Nanowire Sensor Circuitry
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on nanowire arrays, combining light sensors and electronics made of different crystalline materials. Their method can be used to reproduce numerous such... view more... (2008-08-05)
Cold Spring Harbor Protocols features methods for analyzing protein interactions
Cold Spring Harbor Protocols, an online journal that publishes methods used in a wide range of biology laboratories, has added over 40 new peer-reviewed protocols to its archive today. view more (2006-09-11)
Toward plastic spin transistors
University of Utah physicists successfully controlled an electrical current using the "spin" within electrons - a step toward building an organic "spin transistor": a plastic semiconductor switch for future ultrafast computers and electronics. view more (2008-08-18)
Researchers create first nanofluidic transistor, the basis of future chemical processors
University of California, Berkeley, researchers have invented a variation on the standard electronic transistor, creating the first "nanofluidic" transistor that allows them to control the movement of ions through sub-microscopic, water-filled channels. view more (2005-06-30)
Analysis finds strong match between molecular, fossil data in evolutionary studies
During a seminar at another institution several years ago, University of Chicago paleontologist David Jablonski fielded a hostile question: Why bother classifying organisms according to their physical appearance, let alone analyze their evolutionary dynamics, when molecular techniques had already invalidated that approach? view more (2009-04-29)
Professor Eero Vuorio to chair the EMBL Council
Professor Eero Vuorio has been elected to chair the Council of the European Molecular Biology Laboratory (EMBL) in 2003. His predecessor Professor Peter Gruss has assumed office as President of the Max-Planck Society. Professor Vuorio is Professor in Molecular Biology at the University of Turku, Finland, and Chair of the Research Council for... view more... (2002-11-29)
Nanotubes grown straight in large numbers
Duke University chemists have found a way to grow long, straight cylinders only a few atoms thick in very large numbers, removing a major roadblock in the pursuit of nano-scale electronics. view more (2008-04-24)
Genetic Engineering & Biotechnology News reports on growing role of molecular diagnostics
Novel platform technologies and key advances in genomics are rapidly driving the development of molecular diagnostics, reports Genetic Engineering and Biotechnology News (GEN). view more (2008-10-06)
5.1 Surround Sound for FM HD Radio at NAB 2005
Fraunhofer IIS, Telos, Omnia, Axia, Broadcast Electronics and Bose participate in world-premiere live demon-stration of non-matrixed 5.1 Surround Sound for FM HD Radio. view more (2005-04-13)
Photonic Crystals in 3-D - The Physics Congress 2003
Telecoms systems contain an awkward mixture of optics and electronics. A purely optical system would permit the very high data rates needed by the Internet, but at the moment the switching and routing, as well as the "last mile" to the customer, still depend on slower electronic components. Speaking at the Institute of Physics Congress... view more... (2003-03-17)
Rethinking the genetic theory of inheritance
Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases. view more (2009-01-20)
Superconducting sensor helps detecting gravitation waves
To be able to detect gravitation waves in space, physicist have to measure truly minimal displacements: ten billion times smaller than the size of an atom. An improved superconducting sensor is a suitable candidate for this job, Martin Podt of the University of Twente now states in his PhD thesis. He has improved the sensitivity of a so-called... view more... (2003-01-15)
Nanotubes act as 'thermal Velcro' to reduce computer-chip heating
Engineers have created carpets made of tiny cylinders called carbon nanotubes to enhance the flow of heat at a critical point where computer chips connect to cooling devices called heat sinks, promising to help keep future chips from overheating. view more (2006-05-03)
Ultrafast laser spectrometer measures heat flow through molecules
Global warming isn't the only heat scientists are feeling. Another area in which heat flow is becoming crucial is the field of molecular electronics, where long-chain molecules attached to tiny electrodes are used to transport and switch electrons. view more (2007-08-10)
MIT materials scientists tame tricky carbon nanotubes
Based on a new theory, MIT scientists may be able to manipulate carbon nanotubes - one of the strongest known materials and one of the trickiest to work with - without destroying their extraordinary electrical properties. view more (2006-09-19)
Molds for Molecules
Molecular imprints in polymers as reaction vessels for pharmaceuticals research Materials with the tiniest of cavities, which can take up other molecules as "guests", play a meaningful role in science and technology. A particularly interesting process for the synthesis of materials with precisely fitted cavities is known as molecular imprinting.... view more... (2002-11-28)
MIT replaces chrome coatings with safer metal alloys
Ever since the 1940s, chrome has been used to add a protective coating and shiny luster to a wide range of metal products, from bathroom fixtures to car bumpers. view more (2009-05-21)
Science Matters in Northern Ireland
SBS today welcomed the opening of the new Centre for Molecular Biosciences at the University of Ulster, but highlighted the general lack of government investment in science in Northern Ireland. In a talk to scientists in Northern Ireland, Dr Peter Cotgreave, Director of SBS, pointed out that overall government investment in the science base is... view more... (2002-02-01)
