A study by researchers from Stanford University and Veterans Affairs Palo Alto Health Care System suggests that organic food is not healthier or more nutritious than conventional food products. Lead author Dr. Crystal Smith-Spangler and her colleagues studied over 200 works that assessed the health of people who ate organic food. Researchers also looked at studies that compared the levels of nutrients and contaminants found in both organic and conventional poultry, eggs, milk, vegetables, fruits and grains. The results showed that the nutritional content of organic and conventional food was the same, although organic food had only a little more phosphorous, a nutrient that builds strong bones. A few studies also said organic chicken and milk might have more omega-3 fatty acids which are also beneficial to health. The research said that only 7% of the organic food in the studies had pesticide residue, while residue was found on more than 33% of the conventional food samples. According to the researchers, the level of chemical residue in both conventional and organic food is often within the limit set by the US Department of Agriculture. As such, it can be hard to tell how the difference in levels of chemical residue in both foods affects people’s health. Despite the study’s results, many people remain supporters of organic food. Chensheng Lu, a student at the Harvard School of Public Health, said Smith-Spangler’s study was based only on anecdotes. It did not prove that conventional food is safer. He believes that until more studies are done, choosing organic food is still the best way to protect one’s health.

Astronauts from different international space agencies went deep into the caves of Sardinia in Italy for survival training and preparation for their next spaceflight. This training is part of the CAVES project, which stands for Cooperative Adventure for Valuing and Exercising human behavior and performance Skills. The project allows astronauts to work together and help each other through problems and challenging situations. Caves provide a good simulation of the environment in an orbiting spacecraft, since caves are dark and secluded from the world. In caves, astronauts can experience the discomfort and lack of privacy that they will also likely experience in space. The team includes astronauts from NASA, European Space Agency, Russia, Japan and Canada. Three of the team’s members already have spaceflight experiences. The astronauts went down the cave last September 6 and stayed for six days. They tested safety routines and communication systems similar to what they would use in outer space. Aside from exploring the cave, they also surveyed life forms in the cave, as astronauts would do if they were to go to other planets. Test courses for the CAVES project began in 2008. In 2011, five astronauts from NASA, ESA, Russian and Japanese agencies participated in the project. Aside from CAVES, several other space simulation programs exist to train astronauts for difficult space conditions. NASA, for example, is operating its own undersea training mission called NEEMO or NASA Extreme Environment Mission Operations Program.

The Olympic games that ended last August caused a drop in UK retail sales, contrary to hopes that the games would help British economy. In a survey by the British Retail Consortium, retail sales decreased by 0.4% compared to the figures from the same month last 2011. Data also show that the sales in August were the weakest since November last year. Instead of encouraging people to shop, the Olympics led people to just stay home and watch the games. But even online shopping experienced the lowest growth since October 2008. The decline was evident during evenings, when residents opted to watch broadcasts of Olympic events rather than go online shopping. Other products like clothes for women also had low sales, although women’s shoe sales were higher compared to men’s footwear. The number of shop visitors, specifically in central London, also significantly decreased during this period. Not surprisingly, the sales of food and drinks increased as a result of the Olympics plus the hot summer weather. However, these products had poor sales during the rest of the year. Overall, the situation of retail industry in Britain does not look good. Vacancy rates in London shops increased from January to June. According to Local Data Company, an average of 14.6% of retail shops in Britain is empty. This is mainly due to less consumer spending, popularity of online shops and stores moving out to expand. BRC explained that the effect of the Olympics in the low retail sales should not cause panic, since other areas in the country are exhibiting better performance than in London.

More and more children are at risk of suffering from a health problem called Computer Vision Syndrome (CVS) as technology is increasingly used in classrooms. Eye strain, blurred vision, loss of focus and attention, neck pain, double vision, and headaches are the known symptoms of CVS. This condition happens because computer screens make the eyes work harder.  Computer screens give off glare and require the eye to look closely at images that are not as clear as those on paper. In addition, reading on the computer makes eye coordination difficult because computer screens are usually positioned a little higher than the normal reading position.   Thirteen-year-old Casey Connelly who suffers from CVS says she often get “tired eyes” as most of her school work involves computers and electronic tablets. Some schools in the US are now using electronic devices not only for typical activities like typing but also for more advanced function such as storing text books. This set-up requires students like Casey to work longer with computers.  The American Optometric Association (AOA) says that people who spend more than two continuous hours on the computer every day are most likely to develop CVS. To avoid vision problems, Dr. Andrea Thau from AOA suggests taking a 20-second break every 20 minutes spent on the computer. Other tips include positioning the computer screen four to five inches below eye level and blinking often to keep the eyes from getting dry. An annual eye exam before the school year starts may also help students avoid CVS.

Marketers often try to capitalize on tweens who believe the latest toys, gadgets or clothing can make them happy and popular. But a recent study in Netherlands shows that only unhappy tweens put high value on material possessions [puh-ZESH-uhns]. Lead researcher Suzanna Opree from the University of Amsterdam studied the connection between materialism and the happiness of tweens over a long time period. The researchers asked 466 Dutch children, aged 8 to11, to answer questions about the level of their life satisfaction, their attitude towards possessions and the amount of time they spend on watching TV. Opree said this age group was chosen because the tween stage is when materialism starts to develop. Researchers learned that children in the study became materialistic if they were unhappy and watched a lot of television. Opree said the reason for the result may be that these children want the happiness promised by products in commercials. In contrast, materialism did not develop in happy children, even if they watched hours of TV.  Similarly, tweens with low life satisfaction who watched little TV were not very interested in possessions as well. Opree believes parents are important in increasing children’s life satisfaction.  She advises parents to make children watch less TV if the children seem to be developing materialism. She says adults should discuss anything negative they see on advertisements with tweens to lessen tweens’ desire for the products.   In the US, the total yearly spending of tweens amounts to $28 billion, while parents spend $200 billion each year on their tween children.
