In 2002, nuclear engineers Rusi P. Taleyarkhan of Purdue University and Richard T. Lahey Jr. of Rensselaer Polytechnic Institute announced that they had produced thermonuclear fusion by imploding tiny deuterium-rich gas bubbles with sound waves and neutrons. The news about their fusion method--dubbed sonofusion--made headlines worldwide. Yet many skeptics greeted it with scoffing. Now, after repeating the experiments with an improved apparatus, Taleyarkhan and Lahey have more convincing evidence.
In the May 2005 issue of IEEE Spectrum, they discuss their latest experiments in detail and also explain how they plan to turn their tabletop apparatus into a full-scale electricity-generating device. "If this proves possible--and its still a big if--sonofusion could become a revolutionary new energy source," they write.
They also say that other groups may soon have new findings to confirm that sonofusion works. "Now at least five groups--three in the United States and two in Europe--are working on reproducing our sonofusion results," they write. "Some have apparently already succeeded and are now preparing to publish their findings."

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.
