Just released analyses by USDA Forest Service researchers reveal underlying patterns in wildland arson. Research forester Jeff Prestemon and economist David Butry, both from the FS Southern Research Station economics unit at Research Triangle Park, NC, have developed a model that can help law enforcement agencies better predict where and when fires might be set in wildland areas and adopt strategies to reduce the risk of arson.
Over 1.5 million fires are set by arsonists each year in the United States, resulting in over $3 billion in damages. Arson is a leading cause of wildfire in several heavily populated states, including California and Florida. Since wildland arsonists often set fires near homes and roads, arson wildfires cause a disproportionate amount of the damage attributed to wildfire in general. Several recent large wildfires were intentionally set, including the Hayman fire near Denver in 2002, which caused damages exceeding $100 million.
Criminals often commit multiple crimes in a short time frame, a documented phenomenon that researchers call temporal clustering. Temporal clustering of arson events can also be a result of copycat behavior. Property and violent crimes often have a spatial clustering component, also, with crime concentrated in neighborhoods. In a pair of studies, Prestemon and Butry set out to test whether spatio-temporal clustering also appeared in wildland arson. Their research, which described the firesetting process in the context of the economics of crime, also examined whether socioeconomic factors are related to wildland arson in ways identified by criminologists.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
