BMC Neurology has published the results of the HYPNOS I clinical trial demonstrating the sedative action of the Cefaly medical device (http://www.ncbi.nlm.nih.gov/pubmed/22035386).

The results show, in a statistically highly significant manner using four clinical measurement methods, a pronounced reduction in vigilance induced by the action of the Cefaly(R) Hypnos medical device, by comparison to a placebo.

This sedative action on the central nervous system is observed after application for 12 minutes in 83% of individuals whose mean increase in tiredness was of 73%.

36% of post-menopausal women who are treated for estrogen-sensitive breast cancer quit using drugs that help prevent the disease from recurring after four years.

Why? The first study to actually ask the women themselves reports those women quit early because of the medications' side effects, which are more severe and widespread than previously known. A new Northwestern Medicine survey reveals a big gap between what women tell their doctors about side effects and what they actually experience.

Babies love to communicate and they're great listeners, even early on.  

New research shows that during the first year of life, when babies spend so much time listening to language, they're actually tracking word patterns that will support their process of word- learning that occurs between the ages of about 18 months and two years.

A common belief among club-going men is that women choose less attractive friends to make themselves look better. See this clip from that important anthropological documentary "Hall Pass" for context:



Not so, says a group of scientists who have observed the opposite strategy in the Trinidadian guppy, a species of small freshwater fish  - instead, the uglier friends are choosing the prettier females to avoid unwanted male attention. 

Cellebrite, a developer and manufacturer of mobile forensic solutions, has rejected claims in the recent WikiLeaks "Spy Files" exposé that it is among companies that develop and supply equipment to governments and dictators "to spy on their citizens via mobile devices and computers." 

 The WikiLeaks page referring to Cellebrite states, "The Spy Files (open) thousands of pages and other materials exposing the global mass surveillance industry."

A new species of horned dinosaur, Spinops sternbergorum, was announced today by an international team of scientists nearly 100 years after the initial discovery of the fossil.
