At the Institute of Physics conference Photon 04 yesterday, Professor Jim Hough, one of the UKs leading scientists, revealed that he thinks high street bookmakers are crazy to be offering odds of 100-1 on whether Gravitational Waves (wrinkles in relativity) will be discovered before 2010. He has placed a personal bet of £25 – the maximum Ladbrokes allowed him to stake. The available odds were quickly cut from an initial offering of 500-1.
Professor Jim Hough, from the University of Glasgow and one of the leaders of the UK search for Gravitational Waves, said: "I think the real odds are more like a favourite at 2-1 or 3-1, Im almost certain well discover them in the very near future. I would have had much more money on at the odds they were offering but the maximum bet they allowed me to have was £25!" Gravitational waves are ripples in the fabric of spacetime and are one of the more exotic predictions of Einsteins theory of gravity – General Relativity. Initially thought not to exist, the reality of gravitational waves is no longer doubted by scientists. The gradual changes in the orbit of a binary pulsar called PSR 1913 +16 (a pair of orbiting neutron stars, one of which is a pulsar emitting precisely timed radio pulses) can be explained only if angular momentum and energy is carried away from this system by gravitational waves.
Weak gravitational waves are probably passing through us all the time but are too faint to detect. Scientists are currently trying to detect the strongest waves, for example those created in violent events such as supernovae but none of the instruments looking for them have yet picked up a clear and definite signal. Improvements in the sensitivity of these instruments, and some promising initial results, should mean that scientists are very close.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
