(CBS News) Athletes at the London Olympics have a hard enough time competing against the world's best in their respective sports. A new study suggests some athletes who traveled five time zones or more to reach the games may also risk getting sick.

The researchers behind the study, published in the August 8 issue of the British Journal of Sports Medicine, wanted to see the effects travel had on elite athletes. They looked at a study pool of 259 rugby players at the top of their games who were competing at the 2010 Super 14 Rugby Tournament. The tournament took place over 16 weeks from February to May of that year, and consisted of 14 teams from Australia, South Africa and New Zealand.

Throughout the tournament, games were hosted in each of these countries, leading athletes to travel from two to 12 hours away from their home turfs. Eight team doctors were asked to record a daily log of the athletes who needed medical attention because of an illness.

(CBS News) An ingredient used in artificial butter flavoring for popcorn may worsen the effects of an abnormal brain protein that's been linked to Alzheimer's disease.

A new study in Chemical Research in Toxicology examined diacetyl (DA), an ingredient used to produce the buttery flavor and smell in microwave popcorn, margarine, candy, baked goods, and even pet food. It is also created naturally in fermented drinks like beer, and gives some chardonnay wines its buttery taste, according to the study.

Scientists at the University of Minnesota in Minneapolis conducted an analysis of DA, a chemical which previously has been linked to respiratory problems in employees at microwave popcorn and food-flavoring factories.

CBS Minnesota reported that the Minnesota Department of Health was looking into the death of Jack Erenberg, who died from a brain infection called amoebic meningitis on Tuesday. Officials have closed Lily Lake in Stillwater, Minn. where the boy had been swimming prior to the infection.

According to the department, the suspected case of primary amoebic meningoencephalitis (PAM) is a very rare form of meningitis associated with amoeba found in warm freshwater. Officials are working with the CDC to confirm the cause of the child's death and hope to hear results as early as Thursday.

(CBS News) More Americans are walking these days, according to a new report from the Centers for Disease Control and Prevention.

It found that 62 percent of Americans said they walked for at least once for 10 minutes during the week, up from 56 percent of people five years ago.

While the news is a step in the right direction for boosting America's health and fighting the obesity epidemic, the CDC's report also found that less than one-half of Americans engage in the minimum-recommended 2.5 hours (150 minutes) of physical activity each week.

"It is encouraging to see these increases in the number of adults who are now walking," Dr. Joan M. Dorn, chief of the physical activity and health in the CDC's Division of Nutrition, Physical Activity and Obesity, said in a press release. "But there is still room for improvement. People need more safe and convenient places to walk."

Study: Grapefruit juice may boost anti-cancer drug

(CBS News) New research finds a simple modification may make a cancer drug three times more powerful without the side effects a higher dose would likely cause. All it takes is a glass of grapefruit juice.

In the preliminary study published in the August issue of Clinical Cancer Research, scientists at the University of Chicago set out to analyze how certain foods would affect metabolism of the anti-cancer drug called sirolimus, which is an FDA-approved drug to prevent rejection of a kidney transplant and has been seen to help some people with cancer.

The problem with sirolimus, however, is that the drug is easily metabolized and leaves the blood stream before it can show benefits. The optimal dose needed to show anti-tumor benefits also brings with it significant gastrointestinal problems.

Car crashes are the leading cause of death for children older than 3 in the U.S. and cause another 179,000 child injuries each year. According to the Centers for Disease Control and Prevention, child safety seats cut death risk by 71 percent for infant passengers and 54 percent for toddlers between the ages of 1 and 4 - if they are used properly.

3-D printer gives use of arms to 4-year-old

A 3-year-old girl now has the use of her limbs thanks to a 3D printer that allowed doctor's to custom make a device.

(CBS News) A 4-year-old girl with a rare disease that robbed her from using her arms can now pick up toys and play for the first time with the help of a 3D printer.

When Emma Levelle was born, her legs were up by her ears, her shoulders were internally rotated, her fingers were deviated, and she had rocker-bottom feet. Doctors diagnosed her with a condition called arthrogryposis multiplex congenital, her mom said tearfully in a video uploaded to YouTube.

Arthrogryposis is a genetic condition that causes muscles to be abnormally developed and joints to be stiff, according to the Boston Children's Hospital.

(CBS News) Nearly one in four parents or caregivers randomly observed by researchers publicly settled disputes with their child by hitting, spanking or some sort of physical contact, a new study shows.

Researchers at Michigan State University in East Lansing covertly camped out at public areas to get a realistic idea of how children are disciplined outside of a laboratory setting.

Chemotherapy resistance fueled by nearby cells?

(CBS News) Treating cancer patients with chemotherapy may eventually lead to worse cancers coming back once people become resistant to treatment, and scientists now think they've discovered why.

Almost all patients develop resistance to chemotherapy, according to the authors behind the new research, and it's ultimately a deadly consequence for people with cancer that has spread, including those with metastatic breast, prostate, lung and colon cancers.

Swapping out violent TV may improve kids' sleep

(CBS News) Watching violent television shows and movies meant for older kids may take away from young children's sleep.

New research from the August 6 issue of Pediatrics shows that if parents were to swap their child's media viewing habits for positive-minded, age-appropriate TV, he or she may experience a better night's sleep.

For the study, investigators at Seattle Children's Hospital Research Institute studied the sleep schedules of 565 local kids who were between 3 and 5 years old. Half of families were randomly assigned to receive a home visit and several phone calls and letters from a case manager, whose role was to help the family replace violent and age-inappropriate viewing content with more educational or "prosocial" programming. Prosocial programming includes shows that teach a positive message of friendliness, sharing, cooperation and empathy.

Breast Cancer Awareness month tactics questioned

The White House in Washington is bathed in pink light Monday, Oct. 3, 2011, in recognition of October as Breast Cancer Awareness month.

/ AP
(CBS News) Experts are questioning the advertising tactics used during Susan G. Komen's annual breast cancer awareness month, saying the pink-ribbon campaign inaccurately overstates the benefits of mammograms without mentioning the risks.

In a commentary published in the British Medical Journal (BMJ) called "How a charity oversells mammography," two professors at Dartmouth Medical School say breast cancer awareness month, "otherwise known as 'October'" is the most prominent of the 175 officially designated national health observances in the United States.
