Scientists Discover How Loneliness Can Kill

Loneliness can increase the risk of premature death by 14 percent in older adults, according to a study published Monday that posits a physiological basis for the phenomenon. The dangers of social isolation have long been known but its effects on the body have not been well understood, the researchers said in the work published in the Proceedings of the National Academy of Sciences/PNAS. Led by University of Chicago psychologist John Cacioppo, the research team had previously identified a link between solitude and both a heightened expression of genes involved in inflammation and a diminution in the activity of other genes that play a role in the body’s antiviral responses. The result is a weakened immune systems that makes a person who lives alone more vulnerable to illness. In their latest research, the researchers looked at leukocytes, white blood cells that the immune system uses to protect against bacteria and viruses. They found the same shift in genetic expression in the white blood cells of people who lived alone and in social isolation. They also found that loneliness predicted the gene behavior a year or more in advance and conversely that gene expression predicted loneliness measured a year or more later. (Source)

2. How Technology Will Transform Retirement Someday in the near future, being selfish and obsessed with technology might be qualities that senior citizens praise today’s Millennials for. All around the world, young people are hard at work creating technology that will take care of them when they’re older. via: The Wall Street Journal

3. Who’s going to fly those Amazon delivery drones? The short answer is, probably no one. Which is for the best, really. After all, the real reason we don’t have flying cars is because people are bad drivers. And adding a z axis would be like trying to navigate rush-hour traffic in midair. via: ZDNet

Total Recall Sounds Great, But Some Things Should Be Forgotten

Imagine never again forgetting where you parked your car, or that last item you had on your grocery list, or why you walked into this room anyway. If you trust media stories about research currently under way at Defense Advanced Research Projects Agency (DARPA) to build an implantable device to restore memory, you might not have to worry about these memory lapses in the future.

Via his very first tweet, Jeff Bezos announced that his spaceflight company has accomplished a historic first. It sent a rocket to the edge of space and then landed that rocket’s main fuselage gently on dry land.

Most things humans have sent into space are pushed up there by a disposable rocket. Once the rockets do their job, they fall back to earth, usually worse for wear. They have to be rebuilt each time (though sometimes their parts can be reused). That’s an expensive process, especially if you are a private company hoping to bring tourists to space. Virgin Atlantic, Elon Musk’s company SpaceX and Bezos’ Blue Origin all want to do just that. 

And now Blue Origin has paved the way, landing its rocket on its second attempt (the propulsion module was destroyed when they first tried). Here’s the video in full:

Elon Musk responded to the news on Twitter. He pointed out that it requires much greater speed to actually reach orbit than it does to reach the edge of space. (Phil Plait has some good analysis of the exchange over on his Bad Astronomy blog.)

Still, it’s a pretty amazing accomplishment.

Flowers could be blooming on the International Space Station after the New Year

Having already grown lettuce (images above) on the International Space Station, astronauts are now attempting to grow the first flowering plants. On 16th November, NASA astronaut Kjell Lindgren activated the plant growth system named Veggie and its rooting “pillows” containing Zinnia seeds.

“Growing a flowering crop is more challenging than growing a vegetative crop such as lettuce,” said Gioia Massa, NASA Kennedy Space Center payload scientist for Veggie. “Lighting and other environmental parameters are more critical.”

Lindgren will turn on the red, blue and green LED lights, activate the water and nutrient system to Veggie, and monitor the plant growth. The experimental flowers are expected to bloom early 2016, after 60 days of growth.

“Growing the Zinnia plants will help advance our knowledge of how plants flower in the Veggie growth system, and will enable fruiting plants like tomatoes to be grown and eaten in space using Veggie as the in-orbit garden,” said Trent Smith, Veggie program manager at Kennedy. Growing tomato plants on the space station is planned for 2017.

7 Things That Happen When You Go To Space

Told Through Astronaut Scott Kelly’s Tweets

Astronaut Scott Kelly is currently spending a year in space. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. During this one-year mission, Kelly is also participating in the Twins Study. While Kelly is in space, his identical twin brother, retired NASA Astronaut Mark Kelly, will participate in a number of comparative genetic studies.

Here are a few things that happen when astronauts go to the space station:

1. Your personal hygiene takes on a different form:

2. Sleeping arrangements might take some getting used to:

3. Internet services will remind you of the 90s:

4. You never have to do laundry:

5. You get to become immersed in a range of different cultures:

6. All of your water is recycled…yes…that means urine too:

7. You get to see the Earth like never before:
