Chao-Cheng Lin of the National Taiwan University Hospital, Yu-Chuan Li of the National Yang-Ming University, and other colleagues in Taiwan developed the Internet-based Self-assessment Program for Depression (ISP-D). Between September 2001 and January 2002 the team recruited 579 subjects via a popular mental health website. Volunteers were sent a follow-up email one to two weeks after completing the first questionnaire inviting them to re-sit the test, and those who completed the questionnaires were offered a psychiatrist’s appointment to validate the diagnosis.
Results of the first assessment showed that 31% of participants had major depressive disorder, 7% a minor depressive disorder, 15% had some symptoms of depression that did not amount to a full diagnosis of depression (subsyndromal depressive symptoms) and 46% had no depression. Analysis of the retest results show excellent reproducibility for major depressive disorder. The reproducibility was lower for minor depressive disorder, which may be because minor depression is not a stable diagnosis. The psychiatrist’s follow-up revealed that the diagnosis was correct for ¾ of those tested online.
Already between 1/5 and 2/5 of the world’s population suffer from depression, but most remain undetected or go untreated, making it vital to provide more opportunities for diagnosis.
“The ISP-D provides a continuously available, inexpensive, and easily maintained depression screening method that is accessible to a large number of individuals across a broad geographic area,” write the authors. This tool allows people to reliably assess depression in themselves on their own and in a short amount of time.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
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...
