The Swedish Radiation Protection Authority has engaged two internationally well-known epidemiologists to review published epidemiological studies on the relationship between the use of cellular telephones and cancer risk. They are Dr. John D. Boice, Jr. and Dr. Joseph K. McLaughlin from the International Epidemiology Institute, USA.
In their review, no consistent evidence was observed for increased risk of brain cancer, meningioma, acoustic neurinoma, ocular melanoma, or salivary gland cancer, examined over a wide range of exposure measures, including type of phone, duration of use, frequency of use, total cumulative hours of use, tumor location and laterality (concurrence of tumor location with hand normally used during phone conversations).
Dr. Boice and Dr. McLaughlin have also reviewed the Swedish studies by Lennart Hardell et al., which demonstrated an association between the use of cellular phones and cancer. These and a few studies that addressed this concern in the United States are non-informative, either because the follow-up was too short and numbers of cancers too small (USA) or because of serious methodological limitations (Sweden).

In meningococci, the RNA-binding protein ProQ plays a major role. Together with RNA molecules, it regulates processes that are important for pathogenic properties of the bacteria.
Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding...

Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...
In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
