Over 60 percent of the nearly 5,000 genome projects reported in the Genomes OnLine Database involve microbes. It's no surprise. Microbes are important in everything from bioenergy to agriculture and medicine and are involved in Earth’s biogeochemical cycles.
A lot could be done with microbial genomics, says DOE JGI Genome Biology head Nikos Kyrpides writing in Nature Biotechnology, if researchers go beyond the present anthropocentric focus and institute shared standards for genomic data collection and analysis.
University of Haifa-Oranim researchers have managed to make out the “self-irrigating” mechanism of Rumex hymenosepalus, the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert - the first example of a self-irrigating plant worldwide.
The desert rhubarb grows in the mountains of Israel’s Negev desert, where average precipitation is particularly low (75 mm per year). Unlike most of the other desert plant species, which have small leaves so as to minimize moisture loss, this plant is unique in that its leaves are particularly large; each plant’s rosette of one to four leaves reaches a total diameter of up to one meter.
Dye-sensitized solar cells (DSSCs), expected to power Air Force unmanned aerial vehicles (UAVs) in the future because they are an optimum energy harvesting source that may lead to longer flight times without refueling, have gotten a boost by using a flexible film and a thin glass coating with transparent conductive electrodes.
The University of Washington's Multidisciplinary University Research Initiative (MURI) project team, with lead researcher Dr. Minoru Taya is working on the airborne solar cells and found that DSSCs made from organic materials, which use (dyes) and moth-eye film, are able to catch photons and convert them into synthesized electrons that can harvest high photon energy.
Georgia State University researchers are manipulating individual atoms in DNA and forming unique molecules in hopes of understanding the mechanisms of DNA replication and transcription, and perhaps leading to new treatments for diseases.
Chemistry and chemical biology Professor Zhen Huang and his lab were able, for the first time, to manipulate groups of molecules called methyl and phosphate groups in DNA that have been altered to contain selenium in order to bring them close enough together to form hydrogen bonds.
It isn't often that the government gets it right and the energy/climate change policies being jammed through Congress while there is no way to block them could be with us for a long time.
Unless the writing is completely legible and usually modern, even advanced Optical Character Recognition (OCR) systems give rise to transcription problems and provide results with many errors that need to be edited afterwards, a time-consuming process.
The Computational Perception and Learning Research Group in the Computer Languages and Systems Department at the Universitat Jaume I, in collaboration with the Universidad Politécnica de Valencia, have developed a new assisted system for the transcription of written text called 'State', a transcription system that integrates a series of tools with which images can be processed in order to remove noise and clean up the original image.
