DailyDirt: Somewhat Alien Life And Outer Space
from the urls-we-dig-up dept
The rumors had it all wrong. Nobody discovered a new lifeform on a different planet or moon -- but a new bacterium was found in California. (Why are all the alternative lifestyles living in California?) Just when everyone thinks we know how nature works, nature throws us a few curve balls. Keeps things interesting. UPDATE: Arsenic-based life has been debunked by the scientific process.NASA-funded research discovers that arsenic can replace phosphorous in important biological molecules within living bacteria. Nobel prize worthy stuff, folks. update: well, not after this work has been debunked.... [url] New, improved universe. Now with THREE TIMES the number of stars. [url] Dead astronomers sometimes make for good drama. Tycho Brahe is dug up, and he might get a made-for-TV movie based on his life (and suspicious death). [url] Via "anonymous" -- mercury can turn birds gay or something. Apparently, toxic elements can make life more interesting for all kinds of animals. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

It's a fairly accessible piece - I'm no biologist and I followed it fine.

Ah, the world can be a pretty cool place.
One question. Will the mating between carbon and arsenic based life end in death? Just askin'.

There, fixed that for you.
(not saying that space exploration shouldn't be funded, just that NASA is making a big deal out of nothing because they just want money).

Re:
"NASA-funded research discovers that " NASA needs more money because the government has been cutting back their funding.
Anyways, this is hardly surprising. Both Phosphorus and Arsenic are group five elements and so what they will bind to and how they react with other things will be similar (being that they both have five valence electrons).

Re:

Galaxy article
I was really interested in seeing what the article about stars was. Unfortunately, it links to the New York Times.
Thankfully, I was able to find it elsewhere.
Too bad for the New York Times I guess.

Re: Re:
This is the biggest load of nonsense I've ever saw. A moon made of arsenic? Really?
The discovery was made on Earth, not in space. The fact that it could be found in space in the future doesn't make it a space discovery yet. Space related? That's too ambiguous and can cover way too much.
Under your argument, almost every new biological discovery can somehow be twisted to be a space relate one. Not too long ago we didn't know DNA coded for proteins and we didn't even know what proteins are. Hence DNA and proteins are space related discoveries because now we can look for a moon made of DNA and proteins (or the elements that make them up). Every element discovered to be used in cells now becomes a space related discovery. So then why did biologists, and not astronomers, make these discoveries?
Heck, the discovery of the first tree can be said to be a space related discovery, because now we might find a tree in space too since there is a possibility for trees to exist. The discovery of any animal or cell or new bacteria or even the discovery of humans is a space related one, it's possible for them to exist in space too.
Even if arsenic cells can potentially be found in space, that's hardly NASA's domain right now. NASA should stick with space discoveries, what's in space, not making discoveries that could be in space. Let the biologists discover that arsenic can be used for life and then NASA can read that literature and start looking, but for NASA to start taking the role of biologists at this stage seems suspicious.

This is hardly noble prize worthy. Something noble prize worthy would be like a cure to AIDS (though Aids has long been mostly curable thanks to the possibility of genetic engineering. One can genetically engineer bone marrow to produce aids resistant antibodies, but pharmaceutical corporations will not allow it). The noble prize these days has turned into more of a joke than anything. Where are the cures to things? It's not that things aren't curable, it's that there is more incentive to indefinitely treat a disease than to cure anything.
