A careful study by a group of investigators of the University of Giessen suggests that there is no indication for mercury intoxication or amalgam allergy as a cause of somatic complaints.
To deepen the understanding of the numerous unspecific complaints which are related to the dental material amalgam both in patients and physicians, an interdisciplinary case-control study regarding toxicological, allergic, psychological and psychiatric aspects was conducted. Forty patients with amalgam-associated complaints were compared to a well-matched group of 40 amalgam bearers without complaints. Patients and controls underwent a dental examination, which included recording of the quantity, surface area and quality of amalgam fillings, a determination of the mercury load in blood and urine, an allergy examination including patch testing with amalgam and a psychometric assessment with questionnaires noting coping strategies (ABI-UMW-P), interpersonal problems (Inventory of Interpersonal Problems) and self-consciousness (SAM), the NEO Five-Factor Inventory, Symptom Checklist-90-R, Beck Depression Inventory and a screening instrument for somatoform disorders. Patients and controls did not differ with respect to mercury concentrations in body fluids. Only 1 patient was found to have a positive amalgam patch test; various other allergies could be determined in 28% of patients (n = 11). Patients had higher levels of psychic distress, a higher incidence of depression and somatization disorders as well as different styles of coping with anxiety compared to controls. No indication for mercury intoxication or amalgam allergy as a cause of the patients` complaints could be found. The theory of amalgam-related complaints as an expression of underlying psychic problems is supported. Treatment should focus on somatization and changing coping and attribution styles

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
