The Internet will go interplanetary

NASA finished first tests on a system that

could one day be used to automatically relay information between Earth, spacecraft, and astronauts, without the need for humans to schedule transmissions at each point. …

For the test, dozens of images of Mars and its moon Phobos were transmitted back and forth between computers on Earth and NASA’s Deep Impact spacecraft. The craft, which sent an impactor into Comet Tempel 1 in 2005, has been renamed “Epoxi” now that it its mission has been extended to search for extrasolar planets.

Further tests will begin on the International Space Station next year.

Stress physically reshapes the brain

A neuroscience conference in Washington, D.C. this week could stress you out all by itself. Lab rats put in stressful situations — like being immobilized and forced to listen to loud rock music — grow fewer fibers that connect neurons. Stress isn’t that great for people, either.

“Stress causes neurons (brain cells) to shrink or grow,” said Bruce McEwen, a neuroscientist at Rockefeller University in New York. “The wear and tear on the body from lots of stress changes the nervous system.”

He said that stress is “particularly worrying in the developing brain, which appears to be programmed by early stressful experience.”

Stress in early life, even in the womb, can later lead to undesirable changes in behavior and the ability to learn and remember. Other consequences may be substance abuse and psychiatric disorders, researchers said…

“Pre-natal stress can change the brain forever,” said Tallie Baram, a neurologist at the University of California, Irvine. “Stress changes how genes are expressed throughout life.”

Bruce Sterling’s Last Viridian Note

His post before embarking on his next project has been getting a fair amount of attention. At the risk of turning Futurismic into all Bruce all the time, here’s one of my favorite bits:

I strongly recommend that you carry a multitool. There are dozens of species of these remarkable devices now, and for good reason. Do not show them off in a beltpack, because this marks you as a poorly-socialized geek. Keep your multitool hidden in the same discreet way that you would any other set of keys.

That’s because a multitool IS a set of keys. It’s a set of possible creative interventions in your immediate material environment. That is why you want a multitool. They are empowering.

A multitool changes your perceptions of the world. Since you lack your previous untooled learned-helplessness, you will slowly find yourself becoming more capable and more observant. If you have pocket-scissors, you will notice loose threads; if you have a small knife you will notice bad packaging; if you have a file you will notice flashing, metallic burrs, and bad joinery. If you have tweezers you can help injured children, while if you have a pen, you will take notes. Tools in your space, saving your time. A multitool is a design education.

As a further important development, you will become known to your friends and colleagues as someone who is capable, useful and resourceful, rather than someone who is helpless, frustrated and visibly lacking in options. You should aspire to this better condition.

OK. Recommendations for a multitool, anybody?

TV science-fiction: The origin of ‘Doctor Who’

For those of us who like to know where things came from, the BBC Archive Project has posted some amazing memos and reports revealing the thought processes that led to Doctor Who. Typewritten pages with skeptical scrawls reveal conversations with Brian Aldiss and Kingsley Amis. (Imagine such a consultation today.) Wondering if sf could work on tv at all, the network looked at stories like Poul Anderson’s Guardians of Time and C.L. Moore’s “No Woman Born” as possible projects. They almost went with “The Troubleshooters,” about a consulting firm that dealt with otherworldly events. The archive also includes the initial proposal for the series, as well as the (mixed) audience reaction for the first episode of the series that (some of us) know and love.
