After eleven months of politics, now it’s time for some real “core values” – not those of the candidates but those of the great gas giant planet, Jupiter.
The planet Jupiter may have a core of tar, according to new reasearch from WUSTL.
Katharina Lodders, Ph.D., Washington University in St. Louis research associate professor in Earth and Planetary Sciences in Arts & Sciences, studying data from the Galileo probe of Jupiter, proposes a new mechanism by which the planet formed
A European team based in Heidelberg (Germany) and their colleagues from the HEGRA collaboration have discovered a new, unidentified, very high energy gamma-ray source in our Galaxy. This source was detected via ground-based observations of the Imaging Atmosphere Cherenkov Telescope System.
This system of five telescopes is designed to detect the light produced when high energy particles enter the Earth’s atmosphere. The discovery of this source, TeV J2032+4130, is of particular
A powerful new microscope, currently available only in three universities in Europe and the USA, will position Britain as a leading centre for nanomaterials, researchers announce today.
The ultra-high performance analytical electron microscope (AEM) will support research programmes at the London Centre for Nanotechnology (LCN), an interdisciplinary collaboration between Imperial College London and University College London.
It will provide researchers with extremely hig
A long look at a young pulsar with NASA’s Chandra X-ray Observatory revealed unexpectedly rapid cooling, which suggests that it contains much denser matter than previously expected. The pulsar’s cool temperature and the vast magnetic web of high-energy particles that surrounds it have implications for the theory of nuclear matter and the origin of magnetic fields in cosmic objects.
An international team of scientists used the Chandra data to measure the temperature of t
Protein-encapsulated single-walled carbon nanotubes that alter their fluorescence in the presence of specific biomolecules could generate many new types of implantable biological sensors, say researchers from the University of Illinois at Urbana-Champaign who developed the encapsulation technique.
In a paper accepted for publication in the journal Nature Materials, and posted on its Web site, the researchers showed the viability of their technique by creating a near-infrared nan
Going out and about in freezing conditions could become safer thanks to fundamental research at the University of Edinburgh into how we slip on ice.
Using funding from the Engineering and Physical Sciences Research Council (EPSRC) researchers at Edinburgh have built a device, known as a Tribometer, to measure the friction generated as different materials, such as rubber or metal, slip across a sample of ice. The Tribometer is designed to investigate how factors such as temperatur
Physicists across the North of England were rejoicing today at the news that they had been chosen to host a prestigious conference on Particle Physics in 2007.
’The conference is run every two years by the European Physical Society’, said Professor Roger Barlow, of Manchester University. ’They’ve just had their meeting at the CERN laboratory in Geneva. We persuaded them that our facilities and reputation, together with strong support from the many universities an
Turbulent and Colourful LMC Region Imaged from La Silla The Tarantula Nebula is one of the most impressive views in the Southern sky, cf. ESO Press Photos 14a-g/02. Visible to the unaided eye in the Large Magellanic Cloud (LMC), a satellite galaxy of the Milky Way that is located in the direction of the southern constellation Doradus at a distance of about 170,000 light-years, this huge nebula is the prototype of what astronomers refer to as a “Giant HII region”. In this complex of
In 30 years, a nuclear-powered space exploration mission to Neptune and its moons may begin to reveal some of our solar system’s most elusive secrets about the formation of its planets — and recently discovered ones that developed around other stars. This vision of the future is the focus of a 12-month planning study conducted by a diverse team of experts led by Boeing Satellite Systems and funded by NASA. It is one of 15 “Vision Mission” studies intended to develop concepts in the United State
The circuit will improve the computational accuracy and efficiency of quantum computers operating at extremely low temperatures.
Quantum computers require an ambient temperature of approximately -273 degrees centigrade to function properly. The Technical Research Centre of Finland (VTT) is to build a control circuit for such a superconducting computer that will function at very low temperatures. Future quantum computers will be able to crack IT encryption codes and perform searche
Russian researchers offer a fundamentally new approach to the development of gas sensors for fire-prevention detecting devices. In contrast to already known ones, these sensors allow to detect unerringly fire occurrence at its earliest stage. However, this is not a single advantage of the innovation or a sole field of application.
Moscow scientists – specialists of the Institute of Molecular Physics (Russian Research Center) “Kurchatov Institute” have managed to teach fire-preven
Purdue University researchers, in the culmination of a four-year NASA-funded project, have created a method that will enable engineers to design more efficient systems for heating, cooling and other applications in spacecraft for missions to Mars and the moon.
The new method uses a model that was recently shown to be highly accurate in experiments onboard a NASA KC-135 aircraft that creates reduced gravity conditions such as those in earth orbit, on the moon and Mars. The air
One year after Mars Express’ arrival at Mars, the mighty rules of celestial mechanics have again set Christmas as the date for a major ESA event in deep space.
At 1.25 billion km from Earth, after a 7-year journey through the Solar system, ESA’s Huygens probe is about to separate from the Cassini orbiter to enter a ballistic trajectory toward Titan, the largest and most mysterious moon of Saturn, in order to dive into its atmosphere on 14 January. This will be the first man-made obj
In the current issue of Science magazine (Vol. 306, Dec. 3, 2004), scientists from the Max-Born-Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin, Germany, report the direct observation of atomic motions in a semiconductor nanostructure. They use a novel, laser-driven source for ultrashort x-ray pulses to take a movie of atomic motions in a semiconductor nanostructure. “We can observe changes on ultrashort timescales with our femtosecond x-ray diffraction setup”, says
Researchers at the Georgia Institute of Technology have unveiled a fundamental change in the properties of matter. The theoretical finding, that bosons placed in two-dimensional harmonic traps will crystallize when the strength of their repulsive interactions is increased, appears in the December 3 issue of the journal Physical Review Letters (volume 93, article 230405, 2004).
One of two categories of elementary particles, bosons typically form cloudy aggregates called Bose-E
Cutting edge research at the University of Ulster into how to make complex computers and communications systems manage themselves could power the next generation of US space probes, it was revealed today.
Roy Sterritt, from the University’s Computer Science Research Institute, was today addressing NASA scientists in Washington about his research.
Mr Sterritt said that current computing networks are now so complex and difficult to manage that by 2010, 220 million people
