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.

The Holometer, an experiment at Fermi National Accelerator Laboratory, has started collecting data but researchers are not going to wait to start their media blitz; they are throwing out  mind-bending speculation, like that perhaps we live in a hologram.

Much like characters on a television show would not know that their seemingly 3-D world exists only on a 2-D screen, we could be clueless that our 3-D space is just an illusion. The information about everything in our universe could actually be encoded in tiny packets in two dimensions.
