Time to act

The oil spill in the Gulf of Mexico(/America if you ask Colbert) continues to be the big news all over the U.S., as it should be. Jon Stewart on Wednesday night did a segment on President Obama's speech. In that speech the President says we need to work on getting off of oil, well this was Stewart's response:

If this isn't an excuse to get us off of oil I don't know what will. While I know that it will take sometime (we can't just change overnight) there is a way to start making alternatives more acceptable. Start by lowering subsidies to oil companies and increase the subsidies to alternative energy solutions among other things. There is increasing evidence that we are changing the global climate but not only that we are running out of oil it is time to instigate a change before we are forced to make a change because we run out of oil. It is time to act!!!!

What happened to the Science?

I have always been a fan of CNN.com it is a good quick place to get your news. They also are a more neutral site than most other news sites. Now as you may have guessed by reading this blog I tend to read a lot of science articles to keep up to date on science outside of my specific field. This is actually part of why I started reading CNN.com.

Way back in 2004/2005 when I first started my undergraduate education cnn.com had a section of their website that was all about science and technology. A few years ago they changed the tab to just say Tech but when you clicked there you could still typically find science articles under their own heading within that tab. This was fine with me while I like science to get its recognition this at least allowed the science articles to be found and navigated through.

Well within the last few weeks something happened again. The Tech tab now just navigates to articles about technology with science artiles no longer getting billing. Don't believe me take a look at these screen shots from yesterday (click on the images to better see them):

I understand that technology sells and that maybe what draws most people to that section but they should still include the science articles at least under some listing on that page. The only science article on that page at all was this video of Bill Nye talking about the oil spill clean-up.

There is always the possiblity that I am missing something but I did spend a good bit of time looking over the website to see if I could find a science section but with no luck. Do I think CNN will stop covering science related news? No, but I think it will get harder to find the older articles than it used to be. Will I stop going to CNN.com? No, as I have shown before a lot of the other news websites are not much better when it comes to science. All that I want is for CNN.com to make finding their science related articles a little bit easier and not burying them somewhere deep within their website, especially right now.

Colbert rescues the Gulf region

Ok so not really but he is trying to do something!

A few days ago I was talking with several of my colleagues and we were talking about how most major occurrences have relief efforts to try to raise money. We couldn't think of one for the oil spill in the Gulf of Mexico. Then a few days ago this episode of The Colbert Report aired.

If you watched the episode you heard Stephen Colbert mention that all the money from the Bing advertisement would go toward the Colbert Nation Gulf of America Fund. Well today I finally noticed that the link was up on the homepage for his show. This is a great thing and a good way to recommend that you give what you can to help out those who are suffering now or will be suffering later in the region. Just follow this link and please give what you can.

Book Review #5

So this review is going to be a little bit different. The prior 4 reviews had been books that I had read purely for enjoyment this meant that the review was based primarily on how much I enjoyed the book. This book was read so I could more easily catch up on the data as far as the current state of affairs in the study of pterosaurs. The book was The Pterosaurs: From Deep Time by Dr. David M. Unwin.

For those of you who haven't figured out what this book is about it is clearly, look at the title, about pterosaurs. These group of flying reptiles is often misunderstood and is understudied for sure. The number of books about the group is very limited and this book, published in 2006, is the first major work on the subject since 1991, The Illustrated Encyclopedia of Pterosaurs by Dr. Peter Wellnhofer which is fairly outdated seriously 15 years is a long time in sciences.

So as always lets see what the cover flap has to say, its long so you can just skip it if you want:
Here is the first complete portrait of the legendary flying dragons of deep time-the pterosaurs-designed for non-specialists, yet founded on real science of these bizarre creatures. Presented lucidly and accessibly by one of the world's leading experts, David Unwin's book is built on a mountain of new fossil discoveries and the latest research.

About 220 millions of years ago, a group of reptiles took to Earth's vast and open skies. No longer tethered to the ground, the earliest pterosaurs evolved into a multitude of diverse forms, spread around the globe, and ruled the skies until they went extinct along with the dinosaurs about sixty-five million years ago, rarely leaving fossils as a record of their existence. What they did leave was a mystery for paleontologists to solve; an enigma so difficult to crack that it took centuries of false starts and missteps before the path to a true understanding of pterosaurs was uncovered.

Now, an understanding of the fundamental nature of these strange creatures is finally possible. In the last fifteen years, stunning new fossil finds and significant advances in technology have led to a breakthrough in our knowledge of pterosaurs. New fossils of the earliest species were discovered in Italy, a remarkably well-preserved and complete wing was found in Central Asia, and, most extraordinarily, a pterosaur embryo inside an egg was unearthed in China. CAT scanning has let researchers glimpse inside pterosaur skulls and construct three-dimensional images of their bodies from crushed bones, and modern techniques for analyzing relationships between species have revealed surprising insights into the evolution of the group.

Drawing on these and other advances, David Unwin, caretaker of Archaeopteryx and curator at the Museum of Natural History in Berlin, paints pterosaurs and their world more vividly than has previously been possible. He eloquently reconstructs their biology and behavior. Pterosaurs weren't scaly like dinosaurs, but hairy; most were brightly colored and adorned with remarkable head crests; they were excellent fliers with physiologically sophisticated wings; they walked on all fours; and they varied in size from eight inches to forty feet in wingspan. He shows how they lived their lives, raised their young, and interacted with the different environments of Mesozoic Earth. Then, building on his thorough examination of their anatomy and lifestyle, and using the powerful technique of cladistic analysis, Unwin unravels the evolutionary history of pterosaurs and establishes their place in the one great tree of life.

Packed with seventy color and eighty-five black and white illustrations-including eight full-page original color paintings that are scientific recreations of different pterosaur species-The Pterosaurs From Deep Time takes readers on an wondrous expedition back through the lost world of the Earth's deep past.
So if you read all that you probably appreciate how long it took me to type all that for those of you who didn't realize it took forever so I understand why you skipped it. Anyway onto the review.

The book is wonderfully illustrated with beautiful images and other graphics, although the images in Wellnhofer's are slightly better and well there are more of them. It also presents some of the latest research in pterosaurology, well recent in 2006. The book is written quite simply at times but if you don't have some basic anatomy some of the chapters might get a little complicated. It also provides so huge updates that have occurred in the study of pterosaurs since 1991. The author also includes many inside jokes that a non-expert might not get but I found hilarious like this one from page 226:
Curious, eventful and littered with strange characters-one might expect the pterosaur story to have been told on half a hundred occasions. And so it has been, but often only as part of the backdrop to those hoggers of the limelight: the dinosaurs. When pterosaurs have occasionally made it to the center stage the performance barely lasts on scene. Dimorphodon briefly lurches into view; those trust troupers, Rhamphorhynchus and Pterodactylus, go through their fish-juggling routine; Pteranodon sweeps past, all beak and crest; and Quetzalcoatlus is winched on for the grand finale. Cue volcanoes and meteorites, and there is still time enough to retire to the bar for a quick drink while the King of the Tyrant Lizards eats the final curtain.
This book should be a required for all those who want to know anything about pterosaurs. If I have any complaints it is that the book is outdated, imagine how outdated Wellnhofer's is if this one is outdated in 4 years, but that problem should be alleviated later next year, of course after I should be done with my Thesis, with the publication of The Pterosauria (I want this bad!!!). Don't expect this to be an afternoon read it takes a lot of time and with all of his sources referenced you can build quite a large library of pterosaur papers which you might want to reference for a little bit more information when he refers to them. But overall a very informative read that very well summarizes the information on pterosaurs that we have accumulated over the last 200+ years.

2012

I probably wouldn't have come across this had Jen, of BlagHag and boobquake fame, not retweeted it earlier today and I am glad she did. It is a blog post on Skepticblog by Daniel Loxton titled Children Waiting for the End of the World. In it the author says that the children of today are scared for the end of the world not because of fear of nuclear extermination, like the kids of the 60's-80's, but because of the fear the world will end it 2012. At the end of his post he says this:
What do we, as skeptics, do about that [children suffering from fear]? Step one is simply to internalize the same truth again and again and again: when paranormal beliefs burn out of control, people get hurt. Ordinary, smart, good people — people like your loved ones, and mine.

And then, we need to roll up our sleeves. With that in mind, I’d like to ask you to do something this week, something small: try to make someone feel better about 2012. Talk to a friend. Tweet a resource. Share a link.
Well darn it if he hadn't liked to the same things that I would have so I will share the link to his article (see above and what the heck here) but I will also link to the articles he linked to in his post.

The USGS on the "increase" in earthquakes

USGS earthquake fact and statistics

New York Times article by a seismologist

And finally a Skeptic magazine article "A NASA Scientist Answers the Top 20 Questions About 2012"

So continue sharing information and we can relax on this fear and enjoy your life because you only live once.

The Oil Spill

I have been trying to figure out a way to say this for a while now and this is the best that I could come up with. When I say the oil spill I figure most people know what I am talking about but if you don't lets just put it this way. In the Gulf of Mexico right now there was a well that blew up and has been spewing huge amounts of oil into the Gulf for months now, the oil has been reaching the fragile ecosystem that is the marshes and delta of the Mississippi River in Louisiana for the last couple of weeks causing images like this:



Those images are hard to watch and when thinking about the damages caused by this oil spill will be immense. This causes many people to jump to anger and want someone to blame and the most obvious culprit would be BP. For its part BP is taking a good bit of the blame for the spill having offered to reimburse all those effected and to pay for the cleanup. You could also argue that Haliburton and the company that made the fail safe are also partially to blame sure.

While those three are the most direct problem it could very easily be argued that the main culprit is the consumer demand for cheap oil and gas that has led companies to take risks and cut corners. If this oil spill has shown anything it is that oil production is not without its risks and the higher the demand gets for cheap oil the more likely it is that something like this will happen.

I know I may take some flack for saying what I just said and I will admit that I may have some personal bias with both my parents having worked for oil and gas companies for most of my life. I will also admit I have never been on the side of we need to get away from fossil fuels right now. But what I do hope is that this will spark some change in the American culture to hopefully add more of a push toward alternative fuels because if we don't start soon oil prices are only going to go up. One way or another alternative fuels are what will fuel our future
