"Human beings tend to think in terms of regular, symmetrical structures, but nature can be much more irregular," said UC Davis postdoctoral researcher Matthew Holland, the study's lead author. "We found that symmetrical systems of corridors may actually do less good for natural communities than designs with some randomness or asymmetry built in."
Corridors are physical connections between disconnected fragments of plant and animal habitat. A corridor can be as big as a swath of river and forest miles wide that links two national parks, or as small as a tunnel under an interstate highway.
Without such connections, animals cannot travel to food, water, mates and shelter. Plants cannot disperse their pollen and seeds to maintain healthy, genetically diverse populations.
Designing and implementing corridors (sometimes called corridor ecology or connectivity conservation) is a new subfield in environmental science. Holland's research is among the first to help land managers and community planners designing corridors to know what will work and what will not.
Holland's co-author is UC Davis theoretical ecologist Alan Hastings. Hastings is one of the world's mostly highly regarded experts in using mathematical models (sets of equations) to understand natural systems. His analyses have shed light on environmental issues as diverse as salt marsh grass invasions in San Francisco Bay; climate change and coral reefs; and marine reserves and fish populations. In 2006, Hastings received the Robert H. MacArthur Award, the highest honor given by the Ecological Society of America.

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...
