This biodegradable and bioabsorbable metal decomposes from 6 months to 2 years after being transplanted into human body and hence, medical devices made with these materials are expected to reshape the landscape in the field of fracture treatment, as it reminders second operation to take out the device after patient recovery obsolete.
This is a CT image of biodegradable medical device that is connected to nearby bone tissues six months after transplanted into animal bone tissues.

The heart of the research is matching potentials between the matrix structure of metal and the secondary agents on the matrix structure to overcome the fundamental limitation of metal materials, which is speedy degradation. Using this application, new innovative materials can be developed such as metal alloy with the 2nd and 3rd additional elements while still maintaining the electrochemical nature of pure metal. The remarkable achievement was made possible thanks to the Computational Materials Science Laboratory at Kookmin University (led by Professor Cha Phil-ryung), which helped to create the effects of synergy between computer simulation and technology.
With extensive support of the Seoul Strategic Industry Initiative, the key support program of the Seoul City government for Smaller enterprises' R&D, KIST Consortium has succeeded in developing new degradable metal materials inside human body after transplant, and also received approval to clinically test these metals from the Korea Ministry of Food and Drug Safety as a bioabsorbable fixation device to be used in orthopedics and plastic surgery.
KIST was selected as a beneficiary for the Seoul Strategic Industry Support Initiative in 2010 and has been working on the project for 3 years. Further, these findings were published in the 2013 August edition of Scientific Report, a sister magazine of the world-renowned scientific journal, Nature.

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.
