Viruses could become the next generation of environmentally friendly decontaminants, replacing harmful chemicals like chlorine dioxide in cleaning up areas exposed to anthrax spores, according to findings released today at the American Society for Microbiologys Biodefense Research Meeting. Researchers from the Biological Defense Research Directorate in Rockville, Maryland, the Defense Science Technology Laboratory in the United Kingdom, and the University of Maryland Biotechnology Institute presented their findings.
"Decontamination modalities for anthrax to date have centered on the use of toxic biocides (formaldehyde, chlorine dioxide) or gamma radiation. These approaches suffer from the dual handicap of toxicity to man and the environment and/or are extremely expensive," says Leslie Baillie, one of the scientists on the study. "There is an urgent need for strategies which are environmentally friendly, can be used to decontaminate a range of environments with little or no toxicity to fauna and flora and are cost effective."
In the study the researchers investigated the feasibility of using lytic bacteriophage, viruses that specifically target and kill bacteria, to reduce the level of spores made by the bacteria Bacillus thuringiensis a close but harmless relative of the organism that causes anthrax. Treatment of the soil with bacteriophage resulted in a significant reduction in spore contamination.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
