Data collected from GPS collars on more than 100 male and female elk in southwestern Alberta showed U of A researchers the study population could be divided into two categories: bold runners and shy hiders:
Bold-runner elk, both males and females, moved quickly through the study area and preferred to graze in open fields for the most abundant and nutritious grass. GPS data showed shy hiders stayed and grazed on the sparse vegetation of wooded areas and moved slowly and cautiously.U of A researchers found far more bold-runners were taken by elk hunters than shy hiders.
But the GPS data collected over one hunting season shows hunters are going for the most visible or available elk and understandably more, bold-runner elks showed up in the scopes of high-powered rifles.Researchers put GPS collars on a specific group of male elk.
The same held true for a wider age group of 77 female elk in the study. All females between two and nine years of age and identified as bold runners were taken by hunters. All the female elk in that age group identified as shy hiders survived the hunt.
The researchers found something interesting in the survival rate of older female elk.All the females older than nine years survived the hunting season. Ciuti says it shows in females that whether they're bold runner or shy hiders, if they lived to 9 years of age, they adapted to hunters and became less visible targets.

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....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

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...
