Researchers 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.

Every discovery and invention starts with a question.
Find out how scientists dive into the big questions that drive their research in two video presentations from Lawrence Berkeley Lab’s Science at the Theater.
“Questions drive science. Questions that provoke other questions keep science fresh and alive,” explains host Jeff Miller. “In fact, if you think about the root of the word question – quest – it’s really about a journey, it’s about momentum, it’s about a zest for answers that scientists have and need to keep propelling their research forward.” In short, “The questions never stop – and neither do we.”
5 Big Questions: Dark Energy, Electron Microscopy, Energy from Ocean Waves, Climate and Building a Tabletop Accelerator
In this presentation, scientists explore the following questions: Is learning about dark energy going to get us anywhere? When I’m a scientist in 10 years, what will I be able to see with an electron microscope that you can’t see now? Is it possible to power all of San Francisco on ocean wave energy? Is climate change going to kill all the forests in California? What can a tabletop accelerator do that a big one, like the LHC, can’t do?
5 Big Questions: Cancer and Aging, Radiation, Biofuels, Supernovae, Urban Food Initiative
In this presentation, scientists explore the following questions: What causes age-related disease? How can we see radion and how harmful is it? Do insects contain the secrets to sustainable food and energy production? Do we need math to blow up a star? Is sustainable urban food production possible?

As we grow older, we often become concerned about our memory. Dr. Ramin Motarjemi, Assistant Professor of Medicine and geriatrician at UCSD, discusses ways we can keep our brains sharp through all phases of life.

Certainly it is better, easier and cheaper to prevent disease than treat it.
Although preventive medicine has focused traditionally on children and younger adults, current medical thinking is that adults — and especially older adults — also need specific attention to preventive medicine to minimize the chance of acute and chronic illnesses.
This series with UCSF experts on preventive medicine, integrative medicine, and internal medicine reviews current evidence on:
Cancer Prevention and Screening
High Blood Pressure
Diseases of Aging
Nutrition, Exercise, and Healthy Lifestyle Practices
Vaccines for Adults

In the U.S., approximately 60% of men and 50% of women experience trauma at least once, and 7 – 8% of that population will develop Post Traumatic Stress Disorder (PTSD), according to the National Center for PTSD..
In “Posttraumatic Stress and Growth in Older Adults,” sponsored by the Stein Institute for the Research on Aging, Dr. Steven Thorp discusses the effects of PTSD, current treatment methods, and what the future might hold for PTSD patients.
