This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
Cosmologists hope to “hear the shape of space”, namely its topology, by analyzing in detail the temperature fluctuations in the cosmic microwave background radiation (CMB). An international team of cosmologists, including researchers from l’Observatoire de Paris, has recently developped a model for the vibrations of the universe. For the first time [1], they have simulated high resolution CMB maps containing the signatures of a wide class of topologies, for comparison with the forthcoming MAP satell
A Dartmouth researcher is building a case for a “dark energy” – dominated universe. Dark energy, the mysterious energy with unusual anti-gravitational properties, has been the subject of great debate among cosmologists.
Brian Chaboyer, Assistant Professor of Physics and Astronomy at Dartmouth, with his collaborator Lawrence Krauss, Professor of Physics and Astronomy at Case Western Reserve University, have reported their finding in the January 3, 2003, issue of Science. Combining their calc
Combining concepts from electromagnetic radiation research and fiber optics, researchers have created an extreme-ultraviolet, laser-like beam capable of producing tightly-focused light in a region of the electromagnetic spectrum not previously accessible to scientists. Between 10-100 times shorter than visible light waves, the extreme-ultraviolet (EUV) wavelengths will allow researchers to “see” tiny features and carve miniature patterns, with applications in such fields as microscopy, lithography an
Quasars and active galactic nuclei (AGN) are likely powered by matter accretion onto a super-massive black hole located at their center. Before being swallowed by the black hole, matter spirals towards the center, while forming an accretion disc. Unfortunately, such a disc is too small so that one can in general solve it with present day telescopes. But the technique of radio interferometry with very long base (VLBI, with base length of the size of the earths radius) make it possible somehow. I
Don’t worry – you are not the only one who thought this was a nice amateur photo of planet Saturn, Lord of the Rings in our Solar System!
But then the relative brightness and positions of the moons may appear somewhat unfamiliar… and the ring system does look unusually bright when compared to the planetary disk…??
Well, it is not Saturn, but Uranus, the next giant planet further out, located at a distance of about 3,000 million km, or 20 times the distance between the Sun and t
The science minister, Lord Sainsbury, will today open the highest resolution analytical microscope in the world at the CCLRC Daresbury Laboratory in Cheshire. The SuperSTEM (Scanning Transmission Electron Microscope) project is directed by Professor Peter Goodhew at Liverpool University and involves other scientists from the Universities of Liverpool, Cambridge, Glasgow and Leeds.
The microscope is housed in a new purpose-built low-vibration laboratory at the Daresbury Laboratory and will
