Good news for migraine sufferers.  Your treatment may have gotten a little cheaper.  Exercise is often prescribed as a treatment for migraine, though without sufficient scientific evidence that it really works, but research from the Sahlgrenska Academy at the University of Gothenburg shows that exercise is just as good as drugs at preventing migraines. And so are relaxation techniques.

Electrocrystallization, electric-field-induced phase transformation, predicts that under the influence of sufficiently high electric fields, liquid droplets of certain materials will undergo solidification, forming crystallites at temperature and pressure conditions that correspond to liquid droplets at field-free conditions. A study in the Journal of Physical Chemistry C says they have done it.

The researchers set out first to explore a phenomenon described by Sir Geoffrey Ingram Taylor in 1964 in the course of his study of the effect of lightning on raindrops, expressed as changes in the shape of liquid drops when passing through an electric field.

In Jewish and Christian tradition, Moses wrote the Torah, the first five books of the Bible. Recent evidence shows that multiple writers had a hand in composing the text of the Torah and the other books of the Hebrew Bible and of the New Testament are also thought to be composites.
 

Global warming is bad but at least we have a chance to control it.  Simple life hundreds of millions of years ago had to just go with the flow so when global glaciation put a chill on things back then, the only way even simple life in the form of photosynthetic algae could have survived was in a narrow body of water with characteristics similar to today's Red Sea, according to a new study in Geophysical Research Letters.

A particular kind of sugar molecule had a big impact on human evolution and may have directed the evolutionary emergence of our ancestors, according to a new study in  Proceedings of the National Academy of Sciences, the first evidence of a link between cell surface sugars, Darwinian sexual selection, and immune function in the context of human origins

8,000 years ago, which is basically yesterday in geological time, a now-vanished glacial lake covered a huge expanse of today's Canadian prairie and the rich farmland in the Red River Valley. As big as Hudson Bay, the lake was fed by melting glaciers as they receded at the end of the last ice age. At its largest, Glacial Lake Agassiz, as it is known, covered most of the Canadian province of Manitoba, plus a good part of western Ontario and the Minnesota-North Dakota border.
