Cornell University researchers will present new audio evidence supporting the existence of the phantomlike ivory-billed woodpecker Aug. 24 and 25 at the 123rd American Ornithologists Union meeting in Santa Barbara, Calif.
Cornell Lab of Ornithology researcher Russ Charif will begin presenting the new audio evidence at 10:30 a.m. PST Aug. 24 in Lotte Lehmann Hall at the University of California-Santa Barbara (UCSB). Lab members Ron Rohrbaugh and Ken Rosenberg and Director John Fitzpatrick will also make presentations.
One recording suggests the presence of at least two birds: a signature double rap that sounds like an ivory-billed woodpecker drumming on a tree from a distance followed by a closer double rap. This drumming behavior is typical of many large woodpeckers closely related with the ivory-bill. Other recordings include sounds that resemble the ivory-billed woodpeckers distinctively nasal "kent" calls. The sounds were discovered by Cornell audio experts combing through 17,000 hours of audio files from autonomous recording units installed in the Arkansas woods and swamplands.

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...
