A new study offers direction for those examining the illnesses of those working or living near large electrical facilities.
Exposure to light has been proven to inhibit the normal secretion of melatonin from the light-sensitive pineal gland. But light is only one part of the electromagnetic spectrum, occupying a wavelength between 730 and 400 nm. Because light is the only visible portion of the electromagnetic spectrum, other wavelengths may also inhibit melatonin secretion, including the omnipresent magnetic fields generated by the production, transport, and distribution of electricity (50 Hz in Europe, 60 Hz in North America). These fields are encountered in most activities of daily life, from lighting to heating and other routine household applications of electricity.
Past experimental studies of rats exposed to electric or magnetic fields have found a diminution in melatonin secretion. The importance of the length of magnetic field exposure in this inhibitory effect suggests that the effect of these fields on pineal function may be cumulative, at least in rats. In fact, much of the evidence for the melatonin hypothesis is based on data for rodents. But humans and rodents differ with respect to melatonin secretion in two important ways: (1) rodents are nocturnally active, and they show differences in the anatomical location of the pineal gland; and (2) the geometry of the skull may cause stronger eddy currents in field-exposed animals.

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.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
