Each year more than 45,000 Americans suffer burns serious enough to require a hospital stay, according to the American Burn Association. While the traditional therapy of using skin grafts to cover burn sites has improved, a number of problems including scarring, infection and poor adhesion remain.
“Skin grafts involve taking skin (both the upper epidermal and the underlying dermis) from an unburned site on the patient’s body or from a cadaver and grafting it on to the burn wound,” said Craig D. Woodworth, a cell biologist and associate professor at Clarkson University. “Skin grafts often require multiple surgeries. Cadaver skin is scarce and can introduce disease. In the case of extensive burns, large amounts of skin can be created by isolating individual epidermal cells and then expanding their numbers in culture, but the skin simply does not look or function like normal skin. There are no hair follicles, no pores for sweating, and the pigment is often a poor match.”
Woodworth is collaborating with Anja Mueller, a polymer chemist and assistant professor of chemistry at Clarkson, on research to develop an artificial skin that would heal and function like normal skin and could be used successfully for large burns or surgical reconstruction.

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.
