No Fritos; How About Some Worms?

1 Fewer Vending Machines Now Offer Junk Food

Vending machines have gotten such a bad reputation as an unhealthy and unbiquitous source of junk food such as fattening candies and snacks and sugary soft drinks, that thousands of them have either switched to selling alternative merchandise or simply disappeared. Thanks in large part to "healthy snacks" movements in American schools, the trade magazine Vending Times reports that some 134,000 junk food machines either substituted healthier or non-food items or were retired from service between 2007 and 2010. Among the products now available from former food vending machines are iPods, e-readers, prescription drugs, live bait, cameras, headphones, artwork and gold ingots. Despite these new offerings, overall vending machine sales fell by more than 11 percent over that period.

Your Mind Playing Games on You

2 Clothing Can Affect Your Attention to Details

Wearing a white coat you believe belongs to a doctor can increase your ability to pay attention, find researchers from Kellogg School of Management at Northwestern University. The research, published in Journal of Experimental Social Cognition, reveals the attention gains disappear when wearing the same white coat if you believe it belongs to a painter instead. Scientists call the phenomenon enclothed cognition, which is the effect of clothing on cognitive processes. New York Times says the researchers report it wouldn't be enough to simply see a doctor's coat. Instead, you must actually wear the coat and recognize its symbolic meaning for the effect. In this case, you're gaining more of a trait you believe doctors have: great attention to detail.

HIV Hot Spots

3 Six Cities: HIV Rates for Black Women Higher

Women in six U.S. cities are becoming infected with HIV at a rate that's five times the national average, find researchers at Johns Hopkins University. The cities include Atlanta; Baltimore; New York City; New Newark, NJ; Raleigh-Durham, NC and Washington, DC. The HIV infection rate among black women in these cities is closer to the rate in some African countries, finds the study. The yearly infection rate for black women in the cities was 24 per 10,000 black women, compared to the national average of five per 10,000. Los Angeles Times reports that the infection rate in the Congo is 28 per 10,000. The research, conducted by members of the HIV Prevention Trials Network, was funded by National Institutes of Health.

BMI Can Be Wrong

4 Many Overweight in U.S. May Actually Be Obese

Some people classified as slightly overweight by BMI scores may actually be obese instead, finds a new study. Published in PLoS ONE, the research suggests that more than one in three Americans identified as slightly overweight via their BMI scores may really be obese. Researchers analyzed specials scans called dual-energy X-ray absorptiometry (DXA) to find that 64 percent of the patients in the study were obese. However, based on BMI alone, only 26 percent of the same patients were considered obese. DXA scans measure muscle mass, bone density and body fat. While researchers say that it's too costly to perform DXA scans on everyone, an alternative may be a blood test that measures the hormone leptin, used with BMI, to give a more accurate picture of risk for obesity-related diseases.

Some Response in Placebo Group

5 Early Results of Breast Cancer Vaccine Good

A phase 2 study involving 217 women who went into remission after treatment for HER2 positive breast cancer found that a vaccine that trains the immune system to attack any budding tumor cells generates the immune response researchers were hoping for. The HER2-based peptide vaccine AE37 uses a small protein (peptide) present on cancer cells to get the immune system to see the cancer as a foreign invader and attack it. Women either received the vaccine with a stimulant or only the stimulant for six months. Eighty-six percent of women in the vaccine group elicited an immune response while only 27 percent in the control group. Researchers were pleasantly surprised by the response rate of the placebo group. Future studies will be needed to be conducted before it ends up on the market.
