Ethanol, part deux

Monday, July 16th, 2007

Some good news for people who like alternative energy: ethanol is back on the table.

Cellulosic ethanol is ethanol that comes from cellulose instead of sugar. This is good because most plants don’t have a lot of sugar, but all plants have lots of cellulose. So, instead of using food crops, (like corn and sugar cane which have lots of sugar) to create fuel, we can use any crops, like mown grass clippings, fallen tree limbs or corn stalks (instead of corn ears) to create ethanol.

I’ve been working with some cellulose derivatives this summer, and anyone will tell you that while cellulose can be an absolute bitch to work with, once you’ve hammered out the chemistry that leads to the results you want, that shit is dirt cheap and everywhere. Even better news? It doesn’t have that lameass yield that corn does:

Cellulosic ethanol can contain up to 16 times more energy than is required to create it! If that doesn’t sound ridiculously impressive, consider that gasoline contains only 5 times more energy than was required to create it and corn ethanol is totally lame, containing only 1.3 times the energy required to create it.

Yay! Science!: Wine into water

Wednesday, May 2nd, 2007

Awesome.

Scientists and Australian beer maker Foster’s are teaming up to generate clean energy from brewery waste water — by using sugar-consuming bacteria…

The fuel cell is essentially a battery in which bacteria consume water-soluble brewing waste such as sugar, starch and alcohol.

The battery produces electricity plus clean water, said Prof. Jurg Keller, the university’s wastewater expert

Genetically modified chicken will cure your cancer, goes well with stuffing

Sunday, January 14th, 2007

Scientists have created chickens that lay eggs containing proteins that go in anti-cancer treatments.

The Roslin Institute, near Edinburgh, says it has produced five generations of birds that can produce useful levels of life-saving proteins in egg whites.

The work could lead to a range of drugs that are cheaper and easier to make.

10,000 US scientists/experts call for EPA to step up on global warming

Thursday, November 30th, 2006

Raw Story has printed a letter sent to Congress from thousands of US scientists and experts.

In it, our scientific community expresses unconditional recognition of the real dangers of global warming, the impact it’s already had on our planet, and the urgent need for government action to reduce our fossil fuel consumption. Though the EPA has left our planet for dead, at least a huge number of American scientists are trying to do something about it.

My one complaint about the letter is that it occasionally uses the term “climate change,” which is a Republican frame that attempts to make global warming seem more like a pleasant seasonal alteration and less like a potential devastator of modern society.

But that’s a minor issue, and probably one that feeds into their plan. As we all know, whenever the right wants to distract us from their failings, they manufacture absurd definitional arguments. In Iraq, we’re debating over whether the violence constitutes “civil war.” By refusing to acknowledge that it does, Republicans have moved the debate away from the war and the bloodshed (plus the fact that it’s all their fault) and into the realm of semantics. The same thing is true for reproductive freedom. We spend loads of time arguing over whether a zygote is a person or not, but it really doesn’t matter.

Whatever they choose to call it, any time a conservative pulls the “we can’t be sure” card when it comes to global warming, or whenever one chooses to play semantic games about the environment and what warming “really means for the planet,” we should simply refer them to something like this letter. The unanimity from environmental experts is further proof that the debate is over.

Color me jealous: first female space tourist ready to go

Friday, September 15th, 2006

Next week, the first female space tourist will spend a couple of days at the international space station.

Anousheh Ansari is of course filthy fucking rich, and paid about $20 million for the ride. But you need to be rolling in disposable income to make this kind of history – only three guys got up there before her.

Anyway, she seems to have earned it: she’s been as devoted to space as a non-astronaut could possibly be, putting her money where her mouth is and contributing part of the X-prize as well as supporting other space-tourism ventures. I have to admit I kind of like the idea of space tourism and hope she makes it affordable for me by the time I’m 40. Since I don’t plan on being a millionaire, that’ll have to be pretty damn affordable.

I’d like to be able to zip about in space for a few hours myself one day, although today I’d settle for a hot air balloon or blimp ride.

Yay! Science: Dark Matter

Tuesday, August 22nd, 2006

Good Math, Bad Math has an excellent post up (with an animation and everything) on the existence of dark matter, plus a reminder on the importance of good math to good science. Even the non-sciency types should check it out, since dark matter is cool and MarkCC writes pretty accessibly here.

Pluto: A planet on probation

Monday, August 14th, 2006

Pluto’s been stirring up controversy since it was discovered, and this week things finally come to a head.

A new “scientific and simple” proposal to define the word “planet” will be released Wednesday and astronomers will vote on it next week. It is not clear whether the definition will settle a long-running debate on the status of Pluto, however.

Those with the proper credentials and their IAU dues paid up get to vote on the propsal next week, although its still secret if Pluto is in, out or grandfathered in but all those other Pluto-like objects are out.

But even if Pluto is smacked down, it won’t necessarily be out.

Boss said he wouldn’t be surprised if the IAU vote will be split in thirds, much like the opinions of the original committee charged with developing a definition. And he said the vote should not necessarily be the end of the debate. Future discoveries of objects beyond Neptune could force continual re-evaluation of classification systems and nomenclature.

“It’s not necessarily something that should be decided by a vote for all time,” he said. “Science keeps moving.”

I dunno, on the one hand, Pluto never made any goddam sense, and it would be nice to not have to revise the “My Very Educated Mother” mneumonic everytime Neptune and Pluto switch spots. On the other, it’s Pluto, you can’t just demote a planet!*

*Note: Reputable astronomers will not be taking these points into consideration. Well, maybe that last one, and possibly the first one, but I’m pretty sure they’re not too concerned about what singsong quasi-poem children learn to memorize the order of the planets.

Go feminist, young parent

Monday, August 7th, 2006

Raw Story posted a recent study showing sexually degrading lyrical content can impact a teenager’s sexual habits:

Among heavy listeners of sexually degrading music – where men are “studs” and women are sex objects – 51 per cent started having sex within two years, versus 29 per cent of those who listened to little or none of that type of music.

Wingnuts and fundies will see the letters s-e-x and stop there, arguing that we now have proof in hand that talking sex equates to sexual behavior. They’ll extend it beyond music and go straight for sex ed and all forms of sex media. After all, it can’t just be Gene Simmons’ fault, can it?

But let’s remember that the entire phrase is “sexually degrading.” It turns out that sexual lyrics sans degradation are nothing to fear:

Martino said there was no correlation found between sexual behaviour and sexualized lyrics that were not degrading in tone.

Martino said that degrading lyrics teach boys to relentlessly pursue women, while girls view themselves as sex objects.

To summarize for all the people who hear “sex” and then tune everything out after being blinded with repressed lust in the form of moral outrage, in this study sexual content doesn’t correlate to sexual behavior. Objectification does.

Arguably, this data provides some of the strongest proof yet that irresponsible teenage sexual behavior comes not from the exposure to sex as an idea but from instilling the patriarchal sexual hierarchy in children. So now it’s my turn to expand the implications of this study beyond music.

Protective parents want to shield their kids from all sexual influences, but they’ve been barking up the wrong tree. The data demonstrates that the more you respect the sexual autonomy of others, the more you believe in your right to control your own sexual behavior, the less likely you are to do something stupid out of a sense of entitlement or resignation to your fate.

As always, kids will have sex whenever they want, no matter how much a parent tries to prevent it. However, if you go the feminist route and preach equality, you arm your kids with knowledge that encourages responsibility. At the very least, you protect them from patriarchal attitudes that statistically encourage premature sexual behavior.

So don’t panic if your kid listens to sexy music. Panic if they listen primarily to music degrading women as objects of lust. And if they are listening to that kind of music, I would wager that the more you counteract its content with your own message of sexual equality, the better equipped your son or daughter will be to make smart decisions.

Someday, fundies and wingnuts are just going to have to accept that policies of sex-shaming and the promotion of sexual ignorance are far less effective than encouraging a belief in female sexual equality.

35% of all liberals worship the devil

Update: Bwa-hahaha! Shelley is satire? Thanks to the commenters pointing this out. I’m as bad as the dude who missed the boat on that Onion article. Feel free to ignore my commentary, but I recommend the post; I found it entirely believable… for a wingnut.

Yay! Science #2: The Universe

Monday, May 8th, 2006

A little cosmology to help you sound smarter at cocktail parties:

A joint UK-US team has put forward an alternative theory of cosmic evolution.

It proposes that the Universe undergoes cycles of “Big Bangs” and “Big Crunches”, meaning our Universe is merely a “child of the previous one”.

The article also lets you in on just how smart Einstien was-even when he was wrong, he was still right.

Yay! Science! #1: Batteries

Thursday, May 4th, 2006

The European Union is about to have a new battery recycling law:

It says a quarter of all used batteries must be collected by 2012 – rising to 45% by 2016 – and that at least half of them must be recycled.

This is just peachy, because batteries are just full of all kinds of unpleasant crap, like acids and heavy metals. And this kind of program would be difficult to implement in America, where industry could argue that it’s just too damn expensive-handing all that unpleasant crap is not cheap. With this in mind, I bring you the very first edition of Yay! Science!

Solid state flexible batteries.

Brand-spanking new batteries that will usher in an Orwellian age of smartcards and RFID tags – problems that can be handled with laws if we ever manage to shake off this theocratic monarchy and get ourselves some sort of democracy. In the meantime, the new batteries are more enviornmentally friendly, produce equivalent or more power from a smaller-than-conventional battery (getting rid of the acid-and the stuff necessary to contain the acid- is really helpful), and good for thousands of recharges. Initially they will be used in medical applications and RFID tags, you know, small stuff. In the future, however, they could get big enough and powerful enough to drive our electric cars, which by then better damn well be flying electric cars that drive themselves, because I’m going to need cooler stuff as this Yay! Science! bit develops. Hint hint, MIT.
