Two cricket-like creatures establish new insect group.
Probably the remnants of what was once a larger and more widespread group.
Long lost relative of the stick insect.
The first new order of insects to be discovered for more than 80 years has emerged from the mountains of Namibia. The orders first official members are two creatures about 2 cm long that look a bit like a cross between a cricket and a stick insect1.
The group, called Mantophasmatodea, joins the other 30 or so insect orders such as beetles, flies and termites. "If it was in mammals itd be like discovering bats," says Dick Vane-Wright, head of entomology at Londons Natural History Museum.
The Mantophasmatodeas relation to other insects is uncertain. Klass and his colleagues suspect that they are closest to the stick insects and a small group called the Grylloblattodea, found on mountaintops in North America and Asia. Grylloblattodea was the last new order discovered, in 1914.
Sequencing the insects DNA might clarify their place in the tree of life. Evolutionary biologist Michael Whiting, of Brigham Young University, Provo, Utah, is doing this at the moment. But we shouldnt expect cut-and-dried answers, he says.
"Weve known about the other orders for centuries, and we still havent worked out their relationships," Whiting says. "This is one more piece of a large and complex puzzle: its exciting to have the piece, but its not going to provide the answer by itself."

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...
