Epidemiologists have correlated eating over 10 portions per week of tomatoes with an 18 percent lower risk of developing prostate cancer, new research suggests.

Prostate cancer is the second most common cancer in men worldwide and diagnosed rates are higher in developed countries, which some claim means is due to a Westernized diet and lifestyle.

To assess if following dietary and lifestyle recommendations reduces risk of prostate cancer, scholars at the Universities of Bristol, Cambridge and Oxford looked at the diets and lifestyle of 1,806 men aged between 50 and 69 with prostate cancer and compared with 12,005 cancer-free men.

A growing number of consumers are willing to pay a premium for fruits, vegetables and other foods labeled "organic", but whether they're getting what the label claims is another matter. 

For over a decade it has been known that since there is no surprise spot testing of farms, and very little on imported food at all, organic labels may be meaningless. A few years ago, 25 percent of the organic food bought from Whole Foods stores was found to be conventional.

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-associated death worldwide, due to the difficulty in treating this cancer using conventional chemotherapeutic drugs such as doxorubicin, epirubicin, cisplatin, 5-fluorouracil or etoposide.

New simulations hope to uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built. 

"Which produces more light? A country's biggest cities or its many tiny towns?" asks Dr. Andrew Pontzen, University College London cosmologist and lead author of the study. "Cities are brighter, but towns are far more numerous. Understanding the balance would tell you something about the organisation of the country. We're posing a similar question about the universe: does ultraviolet light come from numerous but faint galaxies, or from a smaller number of quasars?"

Listeria is a dreaded bacterium that can be found in foods. The bacterium is notoriously difficult to fight because it has an almost uncanny ability to adapt to changes in its surrounding. In the United States, it is more prevalent in products like raw milk, foods that have not been washed, like organic produce, and improperly handled meat.

A look at 634 couples found that the more often they smoked marijuana, the less likely they were to engage in domestic violence.  

The scholars attempted to clarify inconsistent findings about domestic violence among pot-smoking couples that primarily has been based on cross-sectional data (i.e., data from one point in time). Looking at couples over the first nine years of marriage, the study found:

• More frequent marijuana use by husbands and wives (two-to-three times per month or more often) predicted less frequent intimate partner violence (IPV) perpetration by husbands.

• Husbands' marijuana use also predicted less frequent IPV perpetration by wives.
