An Orange a Day

1 Chocolate and Oranges May Prevent Frailty in Aged

Researchers hope to establish the benefits from vitamin C and cocoa and their impact on frailty among Britain’s elderly. A study run by Beth Philips, Department of Clinical Physiology, University of Nottingham - a world leader in the research of skeletal muscle tissue - hopes to find ways to maintain muscle mass as people age. Using ultrasound technology, Philips is monitoring the impact of cocoa and vitamin C on blood flow that reaches the muscles. "We have shown that as we age the blood flow to our legs in response to feeding is impaired. This means that fewer nutrients and oxygen are able to reach our muscles which may contribute to muscle wasting and ultimately frailty. We want to know if cocoa and vitamin C can help slow down this deterioration,” she says.

Ricky Gervais Used in Study

2 Older People Poor at Detecting Social Gaffes

Ricky Gervais, the recent controversial host of the Golden Globes, was used in a study about detecting social gaffes! The research, published in Psychology and Aging, reveals that people over 60 aren't as good at detecting social gaffes as those ages 18 to 35. Researchers from the University of Otago showed clips of comedian Ricky Gervais portraying David Brent in the British sitcom "The Office," reports MSNBC. Research participants were asked to rate whether the character's behavior was socially appropriate. Findings showed that younger people were better able to detect the gaffes which occurred in half of the clips. Researchers believe that while the difference in detecting gaffes wasn't huge, it does suggest that emotional recognition worsens with age.

Infection Potential Reduced

3 Future Surgeons Might Use Robotic Nurses

Operating rooms of the future may include robotic scrub nurses or hand-gesture recognition, both of which could reduce the length of surgeries and the potential for infection. "It's a concept Tom Cruise demonstrated vividly in the film 'Minority Report,'" says Juan Pablo Wachs, assistant professor of industrial engineering at Purdue University. Surgeons often refer to patient images during surgery, but stepping away from the table to touch a mouse or keyboard adds to surgery time and increases risk for infection. Hand-gesture technology may be used to control a robotic scrub nurse or tell a computer screen what to do. Robotic nurses may also be useful in coordinating emergency response during disasters. New research findings on the technology will be printed in Communications of the ACM.

Friends Activate Reward Center

4 Teens Take More Risks When with Friends

The presence of friends may stimulate reward centers in the teen brain, causing an increase in risk-taking behavior, say researchers from Temple University. Participants included young adults, teenagers 14 to 18 and college students. While inside a brain scanner, they were asked to play four short rounds of a video driving game. In half of the rounds, participants were told that two same-sex friends were watching the game. Teens ran through about 40 percent more yellow lights, plus had 60 percent more crashes with friends watching, reports New York Times. In adults, there were no differences between playing alone or while watched by friends. Researchers also report that brain areas connected with reward displayed increased activity when friends were watching.

Sit Like You Mean It

5 Posture Affects Sense of Power

Sitting up straight increases feelings of power, claim researchers who conducted an experiment involving people answering questions about how powerful they felt while sitting in different positions. The rather involved experiment by Northwestern University researchers revealed that people who sat with an expansive and sprawling posture answered questionnaires in a way that suggested they felt more powerful. In comparison, those who were asked to sit with a constricted posture answered questions in a way that suggested they felt less powerful. MSNBC reports that study author Adam Galinsky, from the Kellogg School of Management at the university, said that the way you sit can make you feel more powerful, which may affect the way others perceive you.

37 Pounds Per Person on Average

6 Fish Consumption at an All-Time High

According to a new report from the Food and Agriculture Organization (FAO), global fish consumption has reached its highest level ever. Each person on earth eats about 17 kilograms per person on average – or about 37 pounds. Fish supplies more than 3 billion people with at least 15 percent of their average animal protein intake, says Richard Grainger, senior FAO fisheries expert. Unfortunately, he adds, that there hasn’t been an improvement in the stocks of fish and continued depletion threatens world food security. Most stocks of the top 10 commercial fish species are fully exploited, warns the agency. China is the world’s top fish producer, bringing in 47.5 million tons of the overall global catch of 145 million.

Contributing to Obesity?

7 Tonsillectomy Could Be Weight Gain Risk Factor

Children who have their tonsils removed tend to gain weight, finds an analysis of four decades worth of studies. One study found that within one year of surgery, the average increase in BMI was about 7 percent among children who had tonsillectomies. Another finds that up to 75 percent of children experienced weight gain in the year following surgery. Study author Anita Jeyakumar MD of St. Louis University is hesitant to suggest that there is a direct link between tonsillectomy and weight gain, but it does raise questions if the surgery may be contributing in some way to the dramatic rise in childhood obesity. Fewer American children are having their tonsils removed today than in years past. Reasons for removing the throat tissue clumps include infection and sleep disordered breathing.

Loyal Customers Not Protected

8 Store Sued for Not Alerting Customers of Recall

Two shoppers plus the advocacy group Centers for Science in the Public Interest (CSPI) have filed a lawsuit against Safeway Supermarkets for not alerting regular customers about two large food recalls over the last couple of years. Consumer Dee Hensley-Maclean purchased crackers and cookies later recalled because of PCA peanut products that were linked to a Salmonella outbreak. Jennifer Rosen bought eggs that were involved in the massive recall last year. Both women used their supermarket loyalty card (Safeway Club) to make the purchases but learned of the recall from other sources. CSPI contends that Safeway is one of the largest supermarket chains without a method for alerting regular customers of food safety issues, putting consumers at risk.

Want Non-Monetary Benefits

9 Female Doctors Earn Less Than Males

A new study published in the journal Health Affairs reveals that newly trained female doctors in the United States are making about $17,000 less than their male counterparts. Co-author Anthony Lo Sasso of the School of Public Health of the University of Illinois at Chicago said he believes the trend is occurring because women are choosing lower-paying primary care positions instead of specializing and they are choosing to work fewer hours. They may also be accepting less pay in exchange for flexible schedules and family-friendly benefits. But that doesn’t explain the entire picture and gender discrimination cannot be ruled out, Lo Sasso said. Women account for nearly half of all US medical students and are projected to make up about one-third of all physicians in the next decade.

The ADHD Diet

10 Dietary Restrictions May Help Kids with ADHD

A five-week restricted elimination diet may be appropriate for kid with attention-deficit hyperactivity disorder (ADHD) to determine if some foods exacerbate their condition according to a study conducted in the Netherlands. One hundred kids were split into the restricted diet group and a one that had a “generally healthy” diet over a five week period. The study revealed that 64 percent of kids on the restricted diet saw a significant improvement in symptoms. Those who improved then had certain foods added to their diet based on blood work to determine if their ADHD got worse. Although the restriction diet requires a lot of effort and time on the part of the parents with the help of an expert, it may provide an alternative for those who do not want to give their children drugs.
