Twins in Space: The Effects of Space Travel on Humans

8232Researchers love identical twins. Because they have the same genetic code, they provide a unique opportunity to determine how environment may lead to developmental differences – i.e. nature vs. nurture.

In this new program from the Stein Institute for Research on Aging, Brinda K. Rana, PhD, shares the results of NASA’s remarkable Twins Study. In March 2015, U.S. astronaut Scott Kelly embarked on a one year mission onboard the international space station. Meanwhile, his identical twin brother, Mark, remained on Earth giving scientists an opportunity to study the long-term effects of space travel on the human body versus normal development.

Ultimately, NASA wants to know what will happen to astronauts as they inch closer to their Mission to Mars. Space is a harsh environment, both physiologically and psychologically. Astronauts must contend with microgravity, disruptions in sleep cycles, radiation, and dietary limitations, as well as confined spaces and isolation from friends and family. What will happen to astronauts after 3 years – the time it will take to get them to Mars and back again?

But these studies not only have implications for the lives of astronauts. Physiologically, space travel mimics the effects of aging on the human body, changes such as cardiovascular decline, vision problems, muscle and bone atrophy, and cognitive impairment. Any discovery that improves the lives of astronauts in space could also be used to help us right here on Earth.

Osteoporosis Update 2017

8232How do you know if you may have Osteoporosis? Should you take calcium or vitamin D supplements? What are the best exercises to keep your bones strong? Find out in this new Stein Institute for Research on Aging program that presents the latest information on osteoporosis.

Osteoporosis is a skeletal disorder that decreases bone density and strength and affects 1 in 3 women (1 in 5 men). Complications from related fractures cause more hospital time for women than many other diseases, including heart attack, stroke, and breast cancer.

According to Heather Hofflich, DO, FACE, Clinical Professor of Medicine, UC San Diego Health System, fractures related to osteoporosis are often a downward spiral, and it’s important to prevent them. If you’re over 50 and experience a fracture, it’s important to alert your primary care doctor to test for bone density to see if you are at risk.

Watch Osteoporosis Update 2017 to learn more about diagnosis, secondary causes, as well as treatment and prevention options.
