Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East and it may have seemed exceptional in the era of 24-hour news, but it's been happening that way for about 4,000 years, according to a new study. 

Since the discovery of the Antarctic ozone hole, scientists, policymakers, and the public have wondered whether we might someday see a similarly extreme depletion of ozone over the Arctic.

A new MIT study finds it isn't a big worry. In the 30 years of international efforts to limit ozone-depleting chemicals, ozone levels in the Arctic haven't yet sunk to Antarctica levels. Picking one solution and declaring it the savior may not be valid; in Canada, ozone-depleting chemicals dropped but ozone still went up, forcing policymakers to scramble and claim it must be coming from Asia.

When it comes to charitable giving, some countries open their collective wallets more than others. According to a new study in the Journal of Consumer Research, people who live in countries that promote equality in power and wealth are more likely to donate money than those who live in societies that expect and accept inequality.

"Our research examines whether cultural values can explain the different levels of charitable giving between different countries," write authors Karen Page Winterich (Pennsylvania State University) and Yinlong Zhang (University of Texas, San Antonio).

New Zealand's pastoral landscapes are some of the loveliest in the world, but they also contain a hidden threat. Many of the country's pasture soils have become enriched in cadmium. Grasses take up this toxic heavy metal, which is then eaten by the cattle and sheep that graze them. The problem is not unique to New Zealand; cadmium-enriched soils being reported worldwide.

The concern is that if cadmium concentrations rise to unsafe levels in meat and dairy products, human health and New Zealand's agricultural economy could be jeopardized. That so far hasn't happened.

WINSTON-SALEM – April 15, 2014 – Vitamin D deficiency and cognitive impairment are common in older adults, but there isn't a lot of conclusive research into whether there's a relationship between the two.

A new study from Wake Forest Baptist Medical Center published online ahead of print this month in the Journal of the American Geriatrics Society enhances the existing literature on the subject.

Food-poisoning outbreaks linked to Escherichia coli are often associated with tainted meat products but up to 30% of these are caused by people eating contaminated vegetables, and that has risen with the popularity of the organic process, as was seen in the 2011 outbreak in Europe that caused 53 deaths.

A new presentation at the Society for General Microbiology's Annual Meeting in Liverpool showed that disease-causing E. coli O157:H7 interacts directly with plant cells, allowing it to anchor to the surface of a plant, where it can multiply.
