Technically we don’t need water in space for drinking because we can recycle our pee. If you’re not really fond of that idea, then you must be very fond of space mining, because otherwise recycled pee is on the menu. It’s really not so bad to drink recycled pee. Here on Earth you do it all the time. It’s just not as easy on a tiny spaceship where the proximity of the recycling equipment forces you to remember where your beverage came from. And recycling on such a small scale as a spaceship is expensive and tricky. Giant spaceships like Earth are better at that stuff. Anyhow, without space mining, you’ll be drinking lots of pee. If on the other hand you have lots of water from mining in space, then your pee can be dumped overboard to make miniature yellow comets in orbit around the sun. Consider it a form of art. So it’s your choice: making space art, or drinking pee.
News you can use.
By the way, I’ve added Phil’s blog to the blogroll.
The new study provides a new hypothesis for how we get old. When people are young, they produce lots of oxytocin. On top of whatever psychological effects it may have, that extra oxytocin also tells stem cells to turn into muscle cells, keeping people strong. Young people might also produce GDF11 and other molecules at high levels, and in combination, they may keep all the organs young. And once those signals start to fade in old age, the body starts to fall apart.
Theoretically, giving old people compounds like oxytocin or GDF11 may cause their cells to act young again. The compounds could be the basis for an all-purpose treatment for the diseases of old age, from osteoporosis to heart disease to Alzheimer’s.
Theoretically.
Yes, theoretically. As he notes, this is only rat experiments. Nothing with humans yet.
When I first bought it, I was unhappy with the battery life, so I bought a spare, for thirty bucks. Last week I bought two for $2.41 apiece. I’ll never be without Droid juice again.
Jeff Foust reports on the NRC report, and reactions to it.
As I tweeted last week, as both a space enthusiast and a taxpayer, I don’t want to spend hundreds of billions of dollars to send a few civil servants to Mars decades from now. Call me completely uninspired.
Last month, another report came out extending the low scores of Millennials to precisely the anti-civic, pro-social syndrome predicted in The Dumbest Generation. It reports the findings of a survey of young adults on a variety of dispositions and beliefs, conducted by Pew Research and bearing the title “Millennials in Adulthood”. The conclusion is neatly summed up in the subtitle: “Detached from Institutions, Networked with Friends.” Overall, it found, 18-33-year-olds in America are less connected to political parties, churches, local associations, and their own country than are older Americans. They are solidly liberal, but their values seem more derived from social attitudes than from political policies, supporting same-sex marriage and “lead[ing] all generations in the share of out-of-wedlock births.” They favor an “activist government,” understood as maintaining entitlements and benefits, not as a political or economic outlook.
In other words, they judge politics by how it affects them, and we see that personal-only perspective in their social focus. They are much more connected to friends and peers than their elders are, with fully 81 percent of Millennials having Facebook accounts, and the “median friend count is 250”! They “are also distinctive in how they place themselves at the center of self-created digital networks,” for example, posting “selfies” at higher rates.
There you have the equation. More peer stuff means less civic sense. While 75 percent of Baby Boomers and 81 percent of the Silent Generation believe the phrase “A patriotic person” fits them “very well,” only 49 percent of Millennials do. Half of them, that is, have little appreciation of their country and fidelity to its traditions. They don’t much care about civics and politics and history, and they don’t know much about it, either. On the 2010 civics exam of the National Assessment of Educational Progress (the Nation’s Report Card), scores for 12th-graders fell three points from 2006 and one-third of test-takers stated that they hadn’t studied the U.S. Constitution at all during the year.
I wish more states would do this. As I wrote in comments there, for decades, I’ve been saying that when I am king, all those stupid signs that say “Slower Drivers Keep Right” will be replaced with “Left Lane For Passing Only.” Because no one thinks that they are a “slower driver.” I’d also put in sensors so that you get an automatic ticket if you’re passed on the right five consecutive times without passing anyone.
