Dr. Oz has recently had the kind of difficulty that popularity brings - he got criticized on the floor of Congress and then got some political theater in the form of a letter to Columbia University asking that he be removed because of his promotion of suspect alternative medicine and even homeopathy treatments.

A new analysis of 1,000 years of temperature records suggests global warming is not progressing as fast as it was projected under the most severe emissions scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC). 

Natural variability in surface temperatures - caused by interactions between the ocean and atmosphere, and other natural factors - can account for observed changes in the recent rates of warming from decade to decade and these "climate wiggles" can slow or speed the rate of warming from decade to decade, or accentuate or offset the effects of increases in greenhouse gas concentrations.

A number of studies have shown that coffee helps to protect against breast cancer and new work led by Lund University has found that it also inhibits the growth of tumors and reduces risk of recurrence in women who have been treated with the drug tamoxifen.

In the cell study, the researchers looked more closely at two substances that usually occur in the coffee drunk in Sweden – caffeine and caffeic acid - and is a follow-up of the results the researchers obtained two years ago. 

Western dietary guidelines support the consumption of dairy but how much of the specific ratios is cultural versus evidence-based has always been a debate.

One thing that has never been debate is if there is anything special about yogurt. Though it has become increasingly popular due to marketing claims about "probiotics" there is no evidence any of it is true, nor is it helping with any of the physical and mental parameters analyzed in a new study of 4,445 Spanish adults.

Little is known about how new mobile technologies affect students' development of non-cognitive skills such as empathy, self-control, problem solving, and teamwork. Two Boston College researchers say it's time to find out.

Lynch School of Education Assistant Professor Vincent Cho and researcher Joshua Littenberg-Tobias, PhD, present a new survey measuring teachers' perspectives on these issues recently at the American Educational Research Association annual meeting session "Examining the Potential of Mobile Technology."

Too many British children die compared to other developed nations and researchers want to know if the reason is relative poverty or low health care funding.

Through data analysis, a research team from Bournemouth University was able to compare the UK to other Western countries and found that the UK has the fourth highest child mortality rate, the third worst relative poverty and lowest funded health care. The upside is its free.

Female liver cells, and in particular those in post-menopausal women, are more susceptible to adverse effects of drugs than their male counterparts, according to new research carried out by the European Commission, Joint Research Centre (JRC).

It is established that women are more vulnerable than men when it comes to drug-induced liver effects, but this is the first time it has been shown that there are differences at cellular level. The findings are clinically relevant, and emphasize the importance of considering sex-based differences in human health risk assessment.

In a small study, Johns Hopkins researchers found that DNA from the sperm of men whose children had early signs of autism shows distinct patterns of regulatory tags that could contribute to the condition.  

Autism spectrum disorder (autism) affects one in 68 children in the U.S. Although studies have identified some culprit genes, most cases remain unexplained. But most experts agree that autism is usually inherited, since the condition tends to run in families. In this study, investigators looked for possible causes for the condition not in genes themselves, but in the "epigenetic tags" that help regulate genes' activity.

A healthy and active old age is a reality for many Europeans and is a genuine possibility for many more, despite the 2008 economic crash and years of austerity measures, according to a new United Nations Economic Commission for Europe (UNECE) and European Commission (EC) report, produced at the University of Southampton.

However, countries such as Greece and Latvia have declined in active ageing capacity during the four years from 2008 to 2012.

As states and the federal government in the U.S. continue to clash on the best ways to improve American education, Canada's Province of Ontario manages successful education reform initiatives that are equal parts cooperation and experimentation, according to a Boston College professor and authority on educational change.

"Although there have been battles in the past, the hallmarks of Ontario's education reform efforts are cooperation and experimentation - with an emphasis on cooperation," said Lynch School of Education Professor Dennis Shirley. "Ontario has struck the right balance. Unfortunately, in the U.S., we squander a lot of energy by fighting with each other. Instead, we should be pulling together to do the real work of improving teaching and learning."
