May offer new approach to smallpox treatment
In a finding that represents an entirely new approach to treating viral diseases such as smallpox, scientists at Dana-Farber Cancer Institute and collaborating institutions have shown that infections can be stymied by interfering with signals used by viruses to reproduce in human cells.
The results, reported in the February issue of the Journal of Clinical Investigation, point to a possible strategy for broadly treating acute viral infections that affect millions of people worldwide. If the technique leads to a drug capable of treating people infected with the smallpox virus, it could eliminate the virus potential as a bioterror agent. "Certain current anti-viral medications have a number of shortcomings that make them less than ideal for treating and/or preventing illnesses," says the studys senior author, Ellis Reinherz, MD, of Dana-Farber. "The existing vaccine against smallpox, for example, poses potential health risks that make it a questionable candidate for protecting the public against an outbreak of the disease. The approach weve taken is based on a new understanding of the basic mechanisms of viral reproduction and movement –– the actual steps that take place once a virus has invaded the body."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
