Resurgence may be due to greater resistance to pesticides, socioeconomic conditions
"Bed bugs were once a common urban plague. But with the development of synthetic insecticides such as DDT and spray systems during the Second World War, they were largely eliminated," says Dr. Tim Myles, an urban entomologist and author of the study published U of T’s Centre for Urban and Community Studies in a recent research bulletin.
Reports of bed bugs by Toronto pest control companies and pest control officials started to increase two years ago.
What can be done to eliminate bed bugs? The research bulletin not only mentions commercial pesticides, but also encourages greater awareness, early reporting, monitoring, cleaning efforts by rooming house and hostel residents, and Integrated Pest Management. Non-chemical approaches include thorough searching and mechanical destruction of bugs and eggs, along with laundering of bedding, frequent vacuuming, and brushing mattress seams. The bulletin also describes the effectiveness of sticky traps and even simple carpet tape, which, placed around a bed or bed legs can trap the bugs.

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...
