Approximately half of all women who seek clinical treatment for migraines have reported an association between migraine and menstruation, and a recent study confirms their experience. In another, unrelated study researchers have identified a drug therapy that is effective in reducing the occurrence or the severity and duration of menstrually associated migraines. Details and outcomes of both studies, and a related editorial, are published in the July 27 issue of Neurology.
Nearly one in five adult women experience migraine headaches, compared with one in twenty adult men. Menstrual migraine is defined as headache that occurs regularly in close relationship to the onset of menstruation (between two days prior to and during the first three days of bleeding). Until recently, studies documenting migraine and menstruation have included small numbers of women over few cycles, often combining data from women using hormonal treatments with those who were not. Also, data has not been collected regarding the difference between menstrual versus non-menstrual migraine attacks within the same woman, rather than comparing attacks within a total population.
Researchers from the City of London Migraine Clinic analyzed diary data from 155 women patients. All of the women tracked at least two cycles, with nearly half of the patients keeping diary cards over the course of four or more menstrual cycles.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
