Scientists at the Department of Energys Pacific Northwest National Laboratory have obtained the most complete protein coverage of any organism to date with the study of a radiation-resistant microbe known to survive extreme environments. This research potentially could open up new opportunities to harness this microorganism, called Deinococcus radiodurans, for bioremediation.
A study published in the Aug. 20 issue of the Proceedings of the National Academy of Sciences observed a 61 percent coverage of the microbes possible predicted set of proteins, or its proteome. This is the most complete proteome reporting to date of any organism. (The proteome is the collection of proteins expressed by a cell under a specific set of conditions at a specific time.) PNNL scientists identified more than 1,900 proteins in D. radiodurans.
Studying the amount of each protein present at any time has become more important as scientists attempt to learn which proteins are involved in important cellular functions. DOEs Microbial Genome Program, an element of the Genomes to Life Program, provided the genomic information for various microorganisms, including D. radiodurans, and developed ways to predict the set of possible proteins, which hold the key to why and how these microbes carry out different functions.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
