British astronomers today (June 24th) saw the first images from an ambitious new programme of discovery, the UKIRT Infrared Deep Sky Survey (UKIDSS). The survey will scour the sky with the world’s most powerful infrared survey camera ( WFCAM) to find some of the dimmest and most distant objects in the Universe. UKIDSS will reach at least twenty times deeper than the largest current survey conducted at this wavelength. Infrared light can be used to study objects that are not hot enough to show up in visible light, such as failed stars in our own Galaxy, as well as objects like distant quasars that are so far away that the expansion of the Universe has shifted their light into the infrared spectrum. UKIDSS will help to solve existing astronomical conundrums, such as when galaxies and quasars first lit up, and will certainly also discover new phenomena, because of the large area and depth.
WFCAM, the Wide Field Camera, was built at the UK Astronomy Technology Centre (UKATC) in Edinburgh, and is mounted on the UK Infrared Telescope (UKIRT) in Hawaii. The new images confirm the power of the camera. The strength of WFCAM comes from the large field of view, equivalent to imaging the full moon in a single exposure, made possible because the camera contains four of the largest available new-generation infrared detectors.
"WFCAM is enormously powerful. We will have surpassed the size of the current best survey after just 2 weeks, and our plan is a survey 100 times greater. It’s about exploring new territory, and we hope to discover new phenomena. In the US they have had tremendous success with the Sloan Digital Sky Survey at visible wavelengths. Now we urgently need a new detailed survey to complement Sloan beyond the visible, in the infrared." said Steve Warren, UKIDSS Survey Scientist from Imperial College.

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.
