More Harm Than Good?

1 Docs Reassess Long-Term Use of Osteoporosis Drugs

Doctors are reassessing the long-term use of osteoporosis drugs because of the possible risk of side effects, including jaw necrosis and esophageal cancer, according to an article in the LA Times. The first osteoporosis drugs were launched about 15 years ago and are taken by millions to offset the bone-thinning disease. Doctors are recommending that some patients take a “drug holiday” by stopping their use for a period of time. "If the bones don't show osteoporosis [after five years of use,] we typically stop the drug and monitor bone density. If they still have osteoporosis readings or have had a fracture, we keep them on medications for out to 10 years," says Dr. Ian Reid, U of Aucklund, NZ. The drugs in question include Fosamax, Boniva, Actonel and Reclast.

More Steps, More Calories Burned

2 Short People Use More Calories While Walking

Taking height and weight into consideration, scientists have developed a new equation to figure out how many calories people burn while walking. The new equation may be used to design more accurate pedometers, or even be used by the military to better predict how many calories a soldier may need, reports MSNBC. Scientists discovered that because people with shorter legs take more steps to cover the same distance, they burn more calories. However, tall people also burn a good number of calories since they're supporting a greater mass against gravity. Researchers also said that after 5 years of age, all people basically walk the same way. Findings were released today in the Journal of Experimental Biology.

Brain Is Busy During Sleep

3 Sleeping Makes Memories Stronger

The brain is hard at work making your memories stronger and reorganized while you sleep, say researchers. Study findings, published in Current Directions in Psychological Science, reveal that during sleep the brain is busy restructuring memories. Study co-author Jessica D. Payne of the University of Notre Dame believes the brain's memory work during sleep helps make it possible for people to come up with new, creative ideas. She says that "People who say they'll sleep when they're dead are sacrificing their ability to have good thoughts now." Payne and co-author Elizabeth A. Kensinger of Boston College also found that people tend to hang on to the most emotional part of a memory, such as a wrecked car.

Concern As Bags Wear and Tear

4 Lead Found in Bags at Two Florida Grocers

The Tampa Tribune reports that it has tested more than a dozen reusable grocery bags sold in Winn-Dixie and Publix stores and found elevated levels of lead, a toxin that can cause learning disabilities in children and fertility problems in adults. The lead appears to be in a form that is not easily extracted, so there is less concern about the metal leaching out into food when the bags are new. The concern is that as the bags wear down, the paint – where the lead is concentrated – can flake off. Publix officials are asking suppliers to find ways to make bags with less lead. Both stores state that the bags are safe, as they meet the current federal laws regarding lead content, but if customers have concerns, they can return the bags for a refund.

He's Not Lovin' It

5 SF Mayor Expected to Veto Happy Meal Ban

"What is wrong with him? How about doing something helpful and limit these disgusting restaurants from adding more locations!"
- Alle Fronteria in the comments

San Francisco Mayor Gavin Newsom is expected to veto the city’s ban on McDonald’s Happy Meals on Friday. The Board of Supervisors approved an ordinance Tuesday that requires fast food children’s meals that contain toys to meet new nutritional standards. Supervisor Eric Mar initiated the proposal because the rate of obesity, particularly among six to eleven year olds, has quadrupled over the past 30 years. Fast food is targeted because it markets high calorie, high fat meals to children, enticing them with “prizes.” Mayor Newsom has scheduled an event today which will outline a new report of the city’s efforts to combat childhood obesity. Unfortunately, however, his veto likely will not stand, as the ordinance passed 8 to 3, a veto-proof margin.
