An analysis of pregnant mothers found that children appear to be less at risk for developing peanut or tree nut allergies if their mothers are not allergic and ate more nuts during pregnancy.

In the United States, the prevalence of childhood peanut allergy has more than tripled from 0.4 percent in 1997 to 1.4 percent in 2010. That corresponds with medical recommendations that mothers eat fewer nuts.

Zaballa (Iruña de Oca) was a medieval settlement abandoned in the 15th century due to urban flight. Prior to that it had a manor monastery and later became something of a specialized factory location before its demise. 

Zaballa is one of the more than 300 deserted settlements known in Alava-Araba - rural spaces abandoned in historical times but now being studied by the UPV/EHU's Cultural Heritage and Landscapes Research Group.  

Sometimes you just have to believe.

Acupuncture has proven to be effective, though it isn't actually being done. When it comes to hot flashes due to breast cancer treatment, even skin pricks used to simulate acupuncture needle sticks might be enough to generate natural chemicals that improve symptoms, which would explain the results.  

The results were that both real and sham weekly acupuncture treatments eased hot flashes and other side effects of anticancer drug treatment, according to the small, preliminary study of breast cancer patients.

Physics can give pointers for energy saving and an can provide materials scientists with tips for the development of high-temperature superconductors.

 Nearly two percent of the electrical energy generated by power stations is lost in the grid. In Germany, for example, this is equivalent to the power delivered by a medium-sized coal power plant. With the fad of windfarms, these losses will increase in the future as power from large offshore energy is transported to the landlocked south.

Cranky old people might think that mellow crooning is less damaging to the voice than beatboxing, with its harsh, high-energy percussive sounds.

Not so, according to a paper in the Journal of Voice.  Beatboxing may be harder on the ears, that is why Michael Bublé gets more downloads than Killa Kela, but it may actually be gentler on vocal cords, which are already injury-prone. His findings were published Dec. 23 online in the Journal of Voice.

The assumption has long been that if mercury is increasing in fish in the North American and European Arctic, the same is true of fish elsewhere in the Arctic.

Not so, according to conservation scientists from the U.S., Russia, and Canada.  Atmospheric mercury comes largely from mining and ore processing, such as smelting, according to United Nations analyses. Under certain water conditions, through the process called methylation, mercury is converted to methylmercury, a special form that can be absorbed by living organisms. Methylmercury is highly toxic.
