A new optogenetic tool, a protein that can be controlled by light, has been characterized by researchers at Ruhr-Universität Bochum. They used an opsin - a protein that occurs in the brain and eyes - from zebrafish and introduced it into the brain of mice. Unlike other optogenetic tools, this opsin is not switched on but rather switched off by light. Experiments also showed that the tool could be suitable for investigating changes in the brain that are responsible for the development of epilepsy.
A phenomenon known from quantum systems could now make its way into biology: In a new study published in Physical Review X, researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) in Goettingen show that the notion of topological protection can also apply to biochemical networks. The model which the scientists developed makes the topological toolbox, typically used only to describe quantum systems, now also available to biology.
The EU funded project DAFNE has developed a methodology for avoiding conflicts of use in transboundary rivers. The model-?based procedure allows for participatory planning and cooperative management of water resources. The aim is now for the DAFNE methodology to be implemented in other regions of the world.
After gaining world attention by 'unboiling' egg protein, Flinders University scientists have now used an Australian-made novel thin film microfluidic device to manipulate Beta-lactoglobulin (β-lactoglobulin), the major whey protein in cow's, sheep's and other mammals. In the latest application, published in Molecules, College of Science and Engineering experts have combined the capabilities of the VFD with a new form of biosensor called TPE-MI, which is an aggregation-induced emission luminogen (AIEgen).
Researchers from Xi'an Jiaotong-Liverpool University have found that an impurity present in many industrial pigmentations drastically reduces the strength and longevity of green architectural concrete.
What The Study Did: Researchers investigated the association between net worth at midlife and subsequent longevity in individuals as well as with siblings and twins.
Researchers at Aalto University have used lignin, a natural polymer abundant in wood and other plant sources, to create a safe, low-cost and high-performing coating for use in construction. As there is a global urge to meet the rising sustainability standards, this new coating has great potential to protect wood, whose use in construction is continually increasing. The new coating is non-toxic, hydrofobic, it retains wood's breathability and natural roughness while being resistant to colour changes and abrasion.
According to the United Nations' telecommunications agency, 93% of the global population has access to a mobile-broadband network of some kind. With data becoming more readily available to consumers, there is also an appetite for more of it, and at faster speeds.
Duke University scientists have developed tests sensitive enough to detect and measure microscopic particles of coal ash in soil, even at concentrations so low and sizes so small that other tests would likely miss them. The four new tests complement tests previously developed at Duke to detect coal ash contamination in water and larger particles of coal ash in soil.
By analyzing peoples' visitation patterns to essential establishments like pharmacies, religious centers and grocery stores during Hurricane Harvey, researchers at Texas A&M University have developed a framework to assess the recovery of communities after natural disasters in near real time. They said the information gleaned from their analysis would help federal agencies allocate resources equitably among communities ailing from a disaster.
