Can an airplane's exit door be opened in mid-flight? If so, how much effort would it take?

Q:What is it like living on Earth after living in space?
R: by Garrett Reisman, Former NASA Astronaut
First of all, the food is much better here on Earth. And taking showers and going to the bathroom are much easier to do here too.

But you do go through a strange adaptation process when you return to Earth. The first thing you notice is that everything seems really heavy. After 95 days on the International Space Station, I returned to Earth in the Space Shuttle Discovery. I took off my helmet and it felt like I was holding the anchor of the U.S.S. Nimitz in my hand. Oh great, I thought, how am I ever going to brush my teeth - the brush will be too heavy!

The next thing you notice is that your vestibular system is all messed up. Just sitting up took a lot of concentration. After about 15 minutes I was able to stand, but I would have keeled right over if there weren't a lot of things to hold onto in the middeck of Discovery.

You see, your brain is remarkably adaptable. After just a few days in space it figures out that your inner ear is producing nothing but garbage signals and so the brain turns the gains of those signals way down in its Kalman filter and cranks up the gains on your visual sensors, the eyes. Then all is well, until you come back to Earth. Now you need your inner ear sensor again, but the brain is still filtering it out. Gradually the brain re-calibrates, but it takes a while.

For me the process went pretty quickly. We don't know why, but anecdotally I can tell you that short and stocky people re-adapt more quickly than tall and lanky folks. This was only the second time in my life that being short came in handy. (The first time being during limbo contests at Bar Mitzvahs in New Jersey in the early 80s.)

After about an hour, I was able to walk around the Shuttle on the runway at the Kennedy Space Center and I was even able to go out to a local bar with my crewmates and I managed to eat half a cheeseburger and half a beer. On my second flight, STS-132, which was only about 2 weeks in duration, we went to the same bar and I had a whole cheeseburger and a whole glass of beer. So when people ask me what was the difference between a long-duration spaceflight and a short-duration spaceflight, I have a quantifiable answer: a half-cheeseburger and a half-beer!

Asian Consumers Still Very Traditional: Survey
A new study finds that traditional values continue to hold sway among Asia’s consumers, who value the family, believe in hard work, and are financially conservative.
Even as personal incomes have increased exponentially, in tandem with the region’s economic growth, a new study finds that traditional values continue to hold sway among Asia’s consumers – and companies would do well to appeal to these values in building their brands in the region.

The inaugural Pan-Asian Wave Consumer Study: Asian Marketing Trends and Consumer Insights, conducted by the Institute on Asian Consumer Insight (ACI) at Singapore’s Nanyang Technological University, has found that Asian consumers value the family, believe in hard work, and are financially conservative. They desire respect for the tremendous progress they have made, and yet shun flashy expressions of wealth.

ACI’s inaugural study for the Asian region polled almost 7,000 consumers from ten key economies in the region, in an extensive investigation of their needs, values, priorities, and beliefs. The six-month-long study was conducted in 14 languages, and received sponsorship from Blackberry, Coca-Cola, DBS Bank and Unilever.

Adam Rutherford's Creation Science (The Real Kind) Part 2
http://www.amazon.com/Creation-Science-Reinventing-Itself-ebook/dp/...
Science journalist, author and Nature editor Adam Rutherford talks about new book Creation: How Science Is Reinventing Life Itself, which looks at the science of the origin of life and at the emerging science of synthetic biology.
Book Description
Publication Date: June 13, 2013
What is life?

Humans have been asking this question for thou­sands of years. But as technology has advanced and our understanding of biology has deepened, the answer has evolved. For decades, scientists have been exploring the limits of nature by modifying and manipulating DNA, cells and whole organisms to create new ones that could never have existed on their own.

In Creation, science writer Adam Rutherford explains how we are now radically exceeding the boundaries of evolution and engineering entirely novel creatures—from goats that produce spider silk in their milk to bacteria that excrete diesel to genetic circuits that identify and destroy cancer cells. As strange as some of these creations may sound, this new, synthetic biology is helping scientists develop radical solutions to some of the world’s most pressing crises—from food shortages to pandemic disease to climate change—and is paving the way for inventions once relegated to science fiction.

Meanwhile, these advances are shedding new light on the biggest mystery of all—how did life begin? We know that every creature on Earth came from a single cell, sparked into existence four billion years ago. And as we come closer and closer to understanding the ancient root that connects all living things, we may finally be able to achieve a second genesis—the creation of new life where none existed before.

Creation takes us on a journey four billion years in the making—from the very first cell to the ground-breaking biological inventions that will shape the future of our planet.

The Art of Science: Supercomputers Help Scientists See What Microscopes and Cameras Can’t Capture
Scientists at GE Global Research have been using the world’s most powerful supercomputers to simulate everything from fuel flowing through jet engine nozzles to water drops turning into ice. The results can be rewarding beyond solving research riddles. “Many times our work generates images that are visually breathtaking,” says Rick Arthur, who leads the Advanced Computing Lab at GRC.

Supercomputers are helping GE engineers speed up innovation, crack previously intractable problems, and shorten the business cycle.
