Why do women get more migraines?  

Differing levels of sex hormones, especially estrogens, may explain why many more women than men suffer from migraines. A study provides evidence that these hormones affect cell mechanisms that control responses to migraine triggers, offering a possible pathway to more effective, personalized treatments.

Glacier depth affects plankton blooms off Greenland  

The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean.

Livestock Infected with Worms Belch and Fart 33% More Methane

Unsurprisingly, there's been renewed interest in reducing those emissions, especially considering the demand for livestock is only growing. Now, ...

The trial was designed to see if cetuximab with radiation would be less toxic than cisplatin with radiation without compromising survival for patients with the disease.
