Metagenomics is the large-scale genomic analysis of microbes recovered from environmental samples as opposed to laboratory-grown organisms which represent only a small proportion of the microbial world.
The UniProt Metagenomic and Environmental Sequences (UniMES) database currently contains the data from the Global Ocean Sampling Expedition (GOS), which was originally submitted to the International Nucleotide Sequence Databases (INSDC).
The initial GOS dataset is composed of 28 million DNA sequences from oceanic microbes and predicts nearly 6 million proteins. By combining the predicted protein sequences with automatic classification by InterPro, the EBI’s integrated resource for protein families, domains and functional sites, UniMES uniquely provides free access to the array of genomic information gathered from the sampling expeditions, enhanced by links to further analytical resources.
Genomics holds the key to understanding the world around us and the metagenomic and environmental data represents a step forward in further charting genomic diversity. Rolf Apweiler from EMBL-EBI and one of the leaders of the UniProt Consortium said, “Throughout the ages, biological events have been the basis and source of medical therapies and industrially important processes. Analysing the genomes of diverse and novel species continues this adaptation of biological innovation for beneficial application”.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
