Biomarkers Provide Clues

1 ID’ing Early Warnings for Cancer

Qing-Xiang “Amy” Sang, FSU, is working to identify “biomarkers” to provide earlier diagnosis of prostate and breast cancers. "Biomarkers are indicators of certain biological and pathological processes that are occurring, such as cancer," says Sang who hopes her research will aid in the early diagnosis of many cancers. “Different types of cancer produce different biomarkers, so the challenge is to identify the most effective one for each type of the disease." The FDA has recognized three biomarkers for breast cancer but, says Sang, “... cancers of the lungs, liver, pancreas, and colon, as well as heart disease, asthma, and cystic fibrosis, currently have no FDA-approved biomarker that can be used to diagnose them early and allow doctors to get a jump on treating them."

Space Three Years Apart

2 Autism Risk: Closely Spaced Pregnancies

The risk of having a child with autism is increased by closely spaced pregnancies, suggest researchers from Columbia University in New York. Study findings revealed that babies conceived before their older sibling reached one year in age had triple the risk of being diagnosed with autism compared with children spaced three years apart, reports CNN. The research, published in the journal Pediatrics, included more than 660,000 children born second in their families in California between 1992 and 2002. Researchers speculate that autism rates may have increased in closely spaced children because the mothers may not have had enough time to build up nutrient reserves of folate and iron.

Heidi Is Fat and Famous

3 Cross-Eyed Opossum Is a Star

Heidi, a opossum abandoned with her brother Teddy outside of an animal shelter in North Carolina, found a new home at Leipzig Zoo in Germany, but she's now a hit for her crossed eyes. Heidi has inspired a hit song on YouTube and a toy, as well as 65,000 Facebook fans. Heidi and her brother will go on display at the zoo in July. According to BBC, zoo officials think that Heidi's eyes may have become crossed due to her diet before she was abandoned or because of her weight problem. Heidi is overweight, and that may cause fat deposits around her eyes. Since Heidi is active at night, she uses her nose, not her eyes, to find her way around. Despite Heidi's wild fame, the zoo isn't trying to actively market her. However, any funds coming from Heidi will be used for supporting rhinos in Borneo.

Strive for Less Than Two Hours

4 Too Much Screen Time Is a Killer

People who spend more than four hours entertaining themselves in front of the TV, computer screen, or with video games face double the risk of having a major cardiac event compared to people who spend less than two hours a day on screen-based entertainment, find UK researchers at University College London. Those who spend too much time on screen-based leisure activities are more at risk of cardiac events that will require hospitalization or result in death, and they're more likely to suffer premature death from any cause, finds the study published in the Journal of the American College of Cardiology. Exercise may not mitigate the negative health impact of spending too much time in front of a screen, warn researchers.

Good News for Eyes

5 Age-Related Macular Degeneration on Decline

Rates of age-related macular degeneration have declined from 9.4 percent of adults ages 40 and over to 6.5 percent, reports CNN. Researchers at the University of Wisconsin, reporting in the Archives of Ophthalmology, found that the number of people in America with age-related macular degeneration has declined by almost a third compared to 20 years ago. A leading cause of blindness, age-related macular degeneration affects central vision and the ability to see fine details. The study, which involved 7,000 people ages 40 and older, also found that non-Hispanic white people, ages 60 and older, are affected by age-related macular degeneration more than others.

Grocer to Post Scorecards

6 Whole Foods to Have Renewed Health Focus

Whole Foods Market, a natural and organic grocer based in Texas, is renewing its focus on healthy foods for shoppers. MSNBC reports that the grocer will display nutritional scorecards to help consumers pick foods with the most nutrients per calorie. Other changes to be rolled out this year include adding healthier prepared foods and baked goods that meet new criteria like bread with no refined flour, plus employing a healthy eating specialist in each store to give tips and demonstrations. Whole Foods Market will also offer more nutrition education. The chain is testing wellness clubs at a few locations. Customers using the wellness club pay a fee for discounts on foods that meet the "Health Starts Here" criteria.

Sweet Now, Sour Later

7 Teen Sugar Consumption Hurting Their Hearts

Teenagers who eat or drink products containing a lot of added sugars could have bad cholesterol profiles, possibly leading to heart disease later in life. The research was published in Circulation: Journal of the American Heart Association. Added sugars are caloric sweeteners that were put into a product by the consumer or manufacturer. Teens with higher added sugar intake had 9 percent higher LDL and 10 percent higher triglyceride levels than teens with the lowest added sugar intake. "Adolescents are eating 20 percent of their daily calories in sugars that provide few if any other nutrients," says study author Jean Welsh of Emory University. Welsh notes that this is the first study to "assess the association of added sugars and the indicators of heart disease risk in adolescents."

Disorders Not Confined to Race

8 Eating Disorders Affecting More Native Americans

A prevailing myth is that eating disorders such as anorexia and bulimia are problems that only affect white girls and women. However, a new study published in a recent issue of the International Journal of Eating Disorders finds that more Native Americans are being diagnosed, particularly with binge eating and purging, but that women are still more likely than men to be affected. The researchers used data from the National Longitudinal Study of Adolescent Health and say their findings further proves that eating disorders are not restricted to a certain race. Lead study author Ruth Striegel-Moore says that more research is needed to identify psychological factors in Native American populations that may lead to the development of eating disorders.

Results in Hours Instead of Days

9 The Development of a Faster Food Safety Test

Food safety scientists are looking for faster ways to detect salmonella, E.coli, listeria and other food pathogens in an effort to catch contaminated food before it leaves a processing facility. Traditional tests can take up to five days, but several companies are working on tests that can deliver results within minutes or hours. Recently, three companies have announced their efforts on developing a faster, yet effective, food safety testing device – Agilent Technologies Inc, DuPont, and Beacon Food Safety. According to the CDC, the US has an estimated 48 million cases of foodborne illness each year. Effective testing devices could not only save lives, but may also extend the shelf life of foods because companies can ship product out sooner after determining they are safe.
