Just as matter can be converted into energy, so too can energy become matter. That’s what five-dozen Jefferson Lab researchers were counting on for an experiment in Hall A
Albert Einstein figured it out by 1905, as he was formulating his special theory of relativity: while you can’t exactly get something from nothing, you can come close. His famous formula, E=MC2, works both ways. Just as matter can be converted into energy, so too can energy become matter.
That’s just what five dozen researchers were counting on with a Jefferson Lab experiment in Hall A that used the Lab’s electron beam and a liquid hydrogen target to bring to life an unusual particle known as a kaon. The kaon’s unique structure could prove of great help to cosmologists, who should be able to use the results of experiments like the Hall A effort to develop structural models of stellar objects made up of exotic, or "strange" matter, matter that includes kaons as part of their own subatomic architectures. Preliminary findings indicate that kaon production results from the interactions of the particles of light known as photons. The photons create more than just kaons, however. They also produce other particles, known as lambda and sigma, with their own distinctive quark structure. All arise from a constantly churning sea of "virtual" particles that can’t exist until bumped by a jolt of energy such as that provided by the Lab’s accelerator.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
