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.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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....
