Super Antioxidant Source

1 Chocolate Is a Super Fruit

When comparing the antioxidant activity in fruit powders with cocoa powder, researchers from Hershey Center for Health & Nutrition found that, gram-per-gram, cocoa powder has more antioxidant capacity, as well as greater total flavanol content. Senior author Dr. Debra Miller, comments, "Cacao seeds are a 'Super Fruit' providing nutritive value beyond that of their macronutrient composition." Researchers also found that, compared to fruit juices, both dark chocolate and cocoa contain greater antioxidant capacity, plus greater total flavanol and polyphenol content. The findings were published in Chemistry Central Journal.

Marketers Can Learn from Suit

2 Age Gain Now Empathy System Reveals Senior Life

Thanks to the Age Gain Now Empathy System, you may not have to wait for a head full of gray hair to understand what it feels like to be elderly. Developed by the Massachusetts Institute of Technology, the system, called Agnes for short, consists of a several elements that help the wearer empathize with older people, such as goggles that diminish vision, plastic shoes with uneven pads to throw off a person's center of gravity, and compression knee bands that discourage bending. New York Times reports that Agnes was developed so that marketers and product designers may better understand seniors, possibly creating more innovative products for them.

Young Moms Have Smaller Babes

3 Newborn Size Linked with Mother's Age

Smaller newborns are more likely to come from younger mothers, while bigger newborns are more likely to have older moms, say Dutch researchers, who found that mothers under 25 have smaller babies. MSNBC reports that researchers from the Erasmus Medical Center in the Netherlands studied 8,568 births among Dutch women between 2002 and 2006. The new research, published in British Journal of Obstetrics and Gynecology, reveals that 4 percent of mothers ages 30 to 35 years old gave birth to small newborns (5.5 pounds or less), compared with 7 percent of moms under 20 years old. Six percent of moms 30 to 35 years old, and about 10 percent of moms over 40, had large babies (10 pounds or more), compared with only 3 percent of the youngest women in the study.

Same Pathway May Be Involved

4 ADHD in Adults May Triple Risk of Dementia

A study conducted in Argentina which looked at 360 patients with dementia compared to 149 matched controls showed that 48 percent of those with Lewy Body Dementia (LBD) suffered from adult attention-deficit and hyperactivity disorder (ADHD). This was compared to 15 percent in the healthy control and the 251 people in the dementia group who suffered from Alzheimer’s. All the adults were assessed for ADHD by to neurologists who were blind to the study and a third was brought in if the first two disagreed. LBD resembles Alzheimer’s and Parkinson’s and researchers believe this results in it being under-diagnosed. Researchers believe that this study does show a link between LBD and ADHD and they hypothesize that the same neurotransmitter pathway in the brain is linked to both conditions.

The Hazardous Hearth

5 Wood Fire Smoke Poses Health Hazard

The wood fires that are keeping people warm in the winter are also the source for very small particles that could cause health problems in people exposed to them, based on a study done in Denmark. Particulate matter, which comes from vehicle exhaust and coal powered plants have been linked to problems such as heart disease, asthma and bronchitis but there is not a whole lot of data on wood smoke particulate matter (WSPM). Airborne particles in WSPM were small enough to go into the deepest part of the lungs, the type most hazardous to human health. Scientific analysis found they contain polycyclic aromatic hydrocarbons (PAH) which are considered “probable” human carcinogens. In the lab, they did more DNA damage and increased inflammation and activated genes that linked to diseases.

Affects Another Gene’s Function

6 Gene Necessary for Heart Function Discovered

Studying mice that were predisposed to developing dilated cardiomyopathy (DCM), researchers at the University of North Carolina at Chapel Hill School of Medicine found a link between the heart condition and the lack of an enzyme produced by a gene called DOT1L. DCM is a condition in which the heart gets large and the walls thin out, inefficiently pumping blood throughout the body. These mice lacked DOT1L and when researchers were able to express a gene located near DOT1L called dystrophin, the mice did not develop the heart condition. It also demonstrated that DOT1L activates genes downstream. Researchers also looked at human heart tissue and found that people with DCM had lower levels of this gene compared to those without the disease.
