The University of Nebraska State Museum’s next Sunday with a Scientist program will explore the world of honeybees. The family-friendly program is 1:30 to 4:30 p.m. May 20 at Morrill Hall.
This isn’t endurance sports related but something near and dear to my heart. I’ve always been fascinated with bees.
I worked a the Nebraska state labs. The state beekeeeper would bring in bees to study for diseases. It was a serious problem. Charlie was a cool dude. I learned a lot from him. You can buy his honey out on Hwy 2 just west of Bennett.
I might have to take that back, Sue Bee honey out of Sioux City sells packets of honey for endurance athletes.
More power to you.

Nearly 500 million adults worldwide are obese—close to 10 percent of men and 14 percent of women, an incidence twice as high as in 1980, according to the World Health Organization. Obesity, defined as a body mass index of 30 or greater, has been linked with higher rates of serious illnesses such as cancer, heart disease, arthritis, and diabetes. But an obesity drug hasn’t been approved in the United States since 1999.
It’s a combination of nature, nurture, technique and body shape, with a bit of history for extra motivation. Nature and nurture are Boonen’s physical gifts and the training he does to maximise them
The increased incidence of iron deficiency in female endurance athletes is thought to be the result of low dietary iron intake in this population, losses of iron in menstrual blood, sweat iron loss, and gastrointestinal blood loss.
We recently learned that women can have orgasms from exercising, and now it seems the pleasures of exercise are even more deeply woven into our evolution. The “runners high” experienced after strenuous exertion was actually key to our species success.
University of Illinois researchers determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss with age.
“These findings are important because we’ve identified an adult stem cell in muscle that may provide the basis for muscle health with exercise and enhanced muscle healing with rehabilitation/movement therapy,” Boppart said. “The fact that MSCs in muscle have the potential to release high concentrations of growth factor into the circulatory system during exercise also makes us wonder if they provide a critical link between enhanced whole-body health and participation in routine physical activity.”
“Although exercise is the best strategy for preserving muscle as we age, some individuals are just not able to effectively engage in physical activity,” Boppart said. “Disabilities can limit opportunities for muscle growth. We’re working hard to understand how we can best utilize these cells effectively to preserve muscle mass in the face of atrophy.”
The results suggest it may be possible to “in some way manage the metabolism of your body through a lifestyle practice,” agreed molecular exercise physiologist Perla Kaliman from the August Pi i Sunyer Biomedical Research Institute in Barcelona, who was not involved in the research. “This shows that there is some molecular evidence to support that notion that exercise is a medicine,” Zierath added.
Prevention trials for vitamins and supplements are notoriously difficult, but some researchers aren’t giving up on finding proof that vitamin D helps ward off disease.
This quote sums it all up. Even science in general. Life is so variable.
“In nutrition we talk about maintaining normal adequacy, but some people may require more vitamins than others, and identifying those populations will really be the future of nutrition,” says Milner. “It’s the classic ‘one size does not fit all.’ I’m hoping we can identify biomarkers that tell us who will really benefit, and who doesn’t need to worry.”
Researchers at National Jewish Health have discovered specific molecular and signaling events by which vitamin D inhibits inflammation. In their experiments, they showed that low levels of Vitamin D, comparable to levels found in millions of people, failed to inhibit the inflammatory cascade, while levels considered adequate did inhibit inflammatory signaling. They reported their results in the March 1, 2012, issue of The Journal of Immunology.
Moving the body demands a lot from the brain. Exercise activates countless neurons, which generate, receive and interpret repeated, rapid-fire messages from the nervous system, coordinating muscle contractions, vision, balance, organ function and all of the complex interactions of bodily systems that allow you to take one step, then another.
