"In recent years, the scientific evidence linking vitamin D to breast cancer has grown notably. Several systematic reviews including randomized clinical trials have recently focused on vitamin D and health outcomes. However, so far, no systematic review has specifically addressed the role of vitamin D supplementation in breast cancer prevention” says Prof. Antonio Giordano, an internationally renowned oncologist engaged for years in the fight against breast cancer.
"The conduct of a systematic review allows to collate all evidence that fits pre-specified eligibility criteria on a specific research question. It is always desirable to review a body of data systematically in that such an assessment holds the potentials to orient future steps and health priorities in a specific research setting. This approach is particularly appropriate when dealing with issues with broad reflections in terms of public health, such as breast cancer related outcomes” adds Prof. Giordano
In this study, the researchers focused on breast cancer, the most commonly diagnosed cancer and the second leading cause of cancer death in women from Western countries. "This systematic review was carried out in full agreement with the methods applied by the Cochrane collaboration, an international not-for-profit organization preparing, maintaining and promoting the accessibility of systematic reviews of the effects of health care and prevention worldwide. Our work contributes a comprehensive appraisal of the evidence stemming from randomized controlled trials on vitamin D supplementation for breast cancer prevention. Based on our results and considering the intrinsic limitations of the scientific evidence examined, vitamin D supplementation seems not to be associated with a reduced risk of breast cancer development in women. However, the scientific panorama related to the association of interest is still limited and overall inadequate to draw firm conclusions” clarifies Dr Barba.
“New trials specifically tailored on the vitamin D-cancer- binomious are in progress and should provide additional information in a few years’ time. Methodological tools and key tenets of vitamin D metabolism and biological activities will help interpret the upcoming results” concludes Prof. Giordano.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
