Happy Thanksgiving!!!

So here in the US today is the annual day when we all stuff our faces with turkey and other foods and give thanks to what we have so:

HAPPY THANKSGIVING!

So I will try to find Thanksgiving related links (so expect a couple more to show up throughout the day)

Brian Switek at Dinosaur Tracking points out that turkeys are just SLIGHTLY modified theropods.

On the theropod tangent David Orr at Love in the Time of Chasmosaurs shows his love for one living theropod.

In one of my favorite weekly posts by David Orr the Vintage Dinosaur Art focuses this week on Dinosaurs' Thanksgiving.

How about some science related food trivia on this big day?

Jeffrey Rowland's guest comic at xkcd today has an interesting theory as to why Thanksgiving was started.

Your Holiday Dinosaur!

Hoping to find some more throughout the day!

151 years ago

Today marks the 151st anniversary of the publication of Darwin's Origin of the species. I do own a copy it is in an anthology called Darwin, the Indelible Stamp which is edited and has Commentary by James D. Watson, yes of DNA fame. I recommend the pick up because it includes The Voyage of the Beagle; On the Origin of Species by Means of Natural Selection; The Descent of Man, and Selection in Relation to Sex; The Expression of the Emotions in Man and Animals.



And the actual book:

Buffalo Commons

This was something I was not aware of till recently due to a discussion and a project I have to do for a class this semester. The reason I probably hadn't heard of it is because I grew up on the east coast so I didn't experience these problems.

When people think of the Great Plains of the United States they probably think of miles and miles of flat terrain covered in corn and other similar crops. While this is true of much of the eastern portion, Iowa good parts of Oklahoma and Texas etc, the western portion, from Montana and North Dakota south, is typically not as lucky. The western portion sits in the leeward side of the Rocky Mountains and this produces a rain shadow effect. North American settlers have tried to conquer this area for close to 200 years with agriculture, this is one of the leading causes of dust bowl. Much of the agriculture in this area is reliant on an aquifer, the Ogallala Aquifer, for their water. This has resulted in a severe depletion of the aquifer since it has been strongly pumped starting in the 1950s. All of these problems have led to this area drastically losing population over the last few decades.

In 1987 Deborah and Frank Popper wrote an article, the full article can be read, in Planning Magazine arguing for the creation of what has been called a Buffalo Commons. This area would be a massive area of land that would be returned to the native grassland conditions. In these areas cattle and other domesticated animals would be removed and instead be replaced by native animals such as bison, pronghorn, and deer (The first two have been greatly reduced in number and range since settlement began as can be read in their respective articles); on a side note I would hope they would also allow replacement of predators such as wolves as well. This land would be treated as a National Park, since it would be bought up by the federal government. This would hopefully increase tourism to this area and may slow or stop the depopulation of the great plains, or at least give those who stay another industry to earn money from.

When the idea was originally proposed there was a huge backlash against the idea. This would make sense many of the farmers and ranchers in this area are hard working, they have to be, and they don't want outsiders telling them what to do. This land still produces a large amount of cattle and the land is still worth a lot of money. Over time, however, there has been a slow growing acceptance for this idea including an article written about a year ago, November 2009, advocating for the creation of the Buffalo Commons (I would link to this but the link is no longer active).

Now I am not trying to advocate, one way or another, about this idea I am just trying to draw attention to this and maybe start a discussion. As I said I wouldn't have known about it had it not been for a project I have to work on in one of my classes this semester and but I feel it is an idea that should be talked about. I can see benefits; no more withdraw on the aquifers, increase in native grasses to help prevent erosion, and tourism being brought to the area; but I can also see negatives; this land will not be available for use later, what do the owners of the land do when their land is bought from them, and the cost of tearing down all that has been built in the area will cost just as much as buying up the land. I only want to bring this idea to a larger population.

Global Climate Change Update

Another great video by Greenman3610 (prior posts here, here, here, here, here, here, and here) this time discussing the sea ice levels for this year. This year's levels were again low and this refutes the claim by the pseudo science blog Watts Up With That.



I also wanted to point everyone toward his website/blog for Climate Denial Crock of the Week.

Potholer54 (prior posts about him and his other channel potholer54debunks can be found here, here, here, and here) summarizes some other research in the scientific community dealing with climate change focusing on hurricanes, atolls, and coral. In general that models predict that we should see fewer hurricanes but those that do form are more likely to be stronger, atolls should continue to grow unless corals stop growing, due to purging of their algae or due to acidification. He mostly focuses on the overreaction of the media to all of these reports, both sides are guilty.


(he lists most of his sources for the hurricane portion in the video description and the rest of his sources are here)

Energy policy is sorely needed!

Pterosaurs Could Fly!

In response to a number of recent papers suggesting that heavy pterosaurs, such as Quetzalcoatlus, might not be able to fly (Chatterjee and Templin, 2004; Wilkinson, 2008; Sato et al., 2009; Henderson, 2010), a new paper was published last week by Dr. Mark Witton and Dr. Michael Habib stating that they could in fact launch themselves and were capable of flight(Witton and Habib, 2010). Most of the media attention focused on the launch part, even though the idea had been published in the past (Habib, 2008), and even some publications that refered to pterosaurs as dinosaurs (argh) I was glad to see the NPR report on the paper that included a few words with Dr. Habib.

GOP and Climate Change

Climate change is happening and we are steadily going to reach the peak production possible for oil, these are facts but they are facts which many, most common among those on the right (this does not exclude everyone on the left nor does it apply to everyone on the right), try to deny, see here. This is why I was glad to see this story late last night in which outgoing Republican Rep. Bob Inglis (SC), a member of the House Science and Technology Committee, chided his colleagues and incoming chair of the committee, Rep. Ralph Hall (R-TX), for denying climate change.
There are people who make a lot of money on talk radio and talk TV saying a lot of things. They slept at a Holiday Inn Express last night, and they’re experts on climate change. They substitute their judgment for people who have Ph.D.s and work tirelessly.
I am glad that Rep. Inglis is supporting science but it is unfortunate that this support of actual science was probably one of the things that did not get him reelected, he lost his primary to a Tea Party candidate. It is sad what many people think about education in this country. The G.I. bill, which allowed vets from WWII to get a college education, is one of the reasons that we became a great country but now it has come to this:



Sometimes I worry about our future.

I am mildly supprised

So the way Louisiana has been I was surprised to see this published by the Louisiana Coalition for Science, for background on this story see my post here.
Readers will have to pardon the mixed metaphors in this post, but something happened today in Louisiana that is is about as common here as snowflakes at Christmas: the voice of reason prevailed at a meeting of public officials.

The Louisiana Textbook/Media/Library Advisory Council met today, Friday, November 12, at 9 a.m. at the Claiborne Building in downtown Baton Rouge. The council voted 8-4 to recommend approval of the biology books that had already been approved by the Textbook Review Committee. Teachers, scientists, and students showed up at this meeting to support the earlier decision of the Textbook Review Committee and to protest the attempt by the Louisiana Family Forum (LFF) to commandeer yet another aspect of Louisiana science education policy.
This is a big win for Louisiana students and I am happy to see that a lot of people showed up in support of science education, although it isn't completely supp rising. I don't have much to say so I will let Barbara Forrest carry us out on this one.
Well, gosh, let’s hope this decision paves the way for BESE’s approval of the textbooks. Regardless of what happens next month, all of us owe a big “thank you” to the good citizens who showed up at that meeting today.

Thank you Baton Rouge Advocate

So after my post last night I was delighted to see this short opinion piece by the Baton Rouge Advocate's opinion staff earlier this afternoon. They argue, and rightly so, that evolution is a science supported by the facts and that Louisiana doesn't want to turn into the next Texas or Kansas and be the laughing stock of the U.S. and even the world.
But it is the duty of the committee members not to be politicians — a couple of the members are state legislators — or representatives of public opinion. The committee members have a duty to reject intrusion of pseudo-science, such as creationism or its offshoot “intelligent design,” into science classrooms.

[...]It’s one thing to be different culturally, as Louisiana is in so many ways. But the facts of science and biology do not change. For Louisiana to be different in the direction of ignorance would be a humiliation in the eyes of the nation and the world.
Let me just say this, thank you Baton Rouge Advocate for supporting true science education!

Louisiana wants to Warn you about Evolution

I first noticed this yesterday as a post by the NCSE on Facebook and then saw today's post over at Louisiana Coalition for Science. The second post give a pretty good summary of the whole history of the attempts to teach creationism in Louisiana. Pretty much this story boils down to there are forces within the Louisiana state education board to put warning stickers on the textbooks teaching about evolution in that it isn't completely true. This isn't the way science works as I have said many times before science is supported by evidence that has been found and experimented on over multiple trials, just because you don't believe it doesn't make it not true. You don't want to learn the science that is fine you just need to find the evidence that supports your claim. Anyway read the second post up above to find out more.

Expelled

Creationists often accuse scientists of preventing those with dissenting opinions from being able to publish or hold positions in science departments etc. The movie Expelled: No Intelligence Allowed was exceptionally guilty of this, among several other classic creationist claims. Well it turns out that one of the main people in that film, William Dembski, was almost fired from his job for saying that the earth was 4.5 billion years old and the universe was ~14 billion. Dr. Michael Zimmerman has a good break down of the whole incident over at the HuffPo and his article is worth the read.

I find the whole incident mildly ironic. Accusing scientists of doing something and then doing the same thing yourself come on now. Also let me point out one thing if creationists were to submit papers that presented evidence that supported their claims then they might get published. The fact that they haven't yet is telling after all science is the search for the truth as to how the universe works if you present facts most scientists will tend to accept them, yes I know this is a little simplified.

Theology and Science = Oil and Water

I typically try to avoid posting about topics dealing with politics, unfortunately this isn't always possible sometimes science and politics mix. As seen in this video and posted about here and here a GOP leader, Rep. John Shimkus (R-Ill.), basically says that we don't have to worry about climate change because God promised Noah that he wouldn't flood the world again.



Now I have no problem with people believing what they want as far as religion is concerned but when you put these people in positions of power I feel that I must say something. What makes this worse is that Rep. Shimkus is trying to head up the House Energy and Commerce Committee. This is the committee that will be in charge of climate policy and his influence could set back support for alternative energy policy by years.

Al Gore Invented Climate Change?

How long have we had evidence supporting global climate change? A video by Greenman3610 (prior posts here, here, here, here, here, and here) show that it has been at least since 1956 and not the new ice age that so many climate change denialists say scientists supported in the 70s, note there were not even very many of those.



So maybe that was an isolated situation right? Well apparently it was a big enough deal to have make it to the Bell Telephone Hour.



While I am posting video's I might as well post Greenman3610's newest video as well dealing with how Hollywood has viewed climate change over the years.

Are GMOs Evil?

This is a question that C0nc0rdance (previous posts showing his videos, here and here) takes up in his newest YouTube video.



This is an important topic because I know plenty of people who are skeptical about many crazy claims but accept that GMOs are always bad. Yes they can be bad but they are not always bad and in the long run we as a moral species have a duty to our fellow humans and when millions of people go to bed hungry or die of starvation every year we have a problem that needs to be fixed.

GSA Position on Climate Change

I have been looking for this for a little while now because I knew one had been published but I was finally able to locate the Geological Society of America's stance on global climate change.
Position Statement. Decades of scientific research have shown that climate can change from both natural and anthropogenic causes. The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s. If current trends continue, the projected increase in global temperature by the end of the twenty-first century will result in large impacts on humans and other species. Addressing the challenges posed by climate change will require a combination of adaptation to the changes that are likely to occur and global reductions of CO2 emissions from anthropogenic sources.
It is worth taking the time to look through the whole thing which includes recommendations for what governments need to do to help slow or limit the change.

Religion forces evolution?

The answer is yes at least to some fish in Southern Mexico at least according to a study published recently in Biology Letters. Apparently a religion that predated Columbus' discovery of North America used to more or less create a poison to the fish while praying for a good year rain wise. Well this apparently has created some fish that have become immune to the poison. An article about the paper in ScienceDaily also had this to say:
"The cool thing is that this ceremony has gone on a long time and that the fish responded to it evolutionarily," Tobler says. "Lots of species couldn't live with these changes. It highlights how nature is affected by human activity."

Rosenthal contends that the idea of imposing evolutionary divergence on a species at an extremely localized spatial scale is not a new concept. In fact, he says, it's been happening since the beginning of humankind and that the idea of the "noble savage" is passé.

"We tend to have this wonderful Pocahontas idea that before Europeans came in, everything was pristine and in harmony with nature and that all of the changes in our environment have been post-industrialization," he explains. "No. People have been changing the environment forever."
Whether we want to admit it or not we are part of this planet and we can effect it in many different ways. This is something we must all understand because too often we look at ourselves as better than other animals when we are in fact just another animal. This gets forgotten about especially when it comes to climate change.

Another, Sometimes, Asexual Vertebrate

When most people think about asexual reproduction they typically think about single celled organism. While rare it has been observed in some more complex animals as well but seems to get even more rare as we get to more derived forms with an occasional appearance in some lizards. Science Daily has an article today about a new paper that discusses asexual reproduction in a Boa constrictor. But there are some weird things about this as well.
Snake sex chromosomes are a bit different from those in mammals -- male snakes' cells have two Z chromosomes, while female snakes' cells have a Z and a W chromosome. Yet in the study, all the female babies produced by asexual reproduction had WW chromosomes, a phenomenon Booth says had not been seen before and was believed to be impossible. Only through complex manipulation in lab settings could such WW females be produced -- and even then only in fish and amphibians, Booth says.

Adding to the oddity is the fact that within two years, the same boa mother produced not one, but two different snake broods of all-female, WW-chromosome babies that had the mother's rare color mutation. One brood contained 12 babies and the second contained 10 babies. And it wasn't because she lacked options: Male snakes were present and courted the female before she gave birth to the rare babies. And the versatile super-mom had previously had babies the "old-fashioned way" by mating with a male well before her two asexual reproduction experiences.
So for some odd reason she choose not to mate with the available males so obviously this is something that needs to be studied more in depth. I would like to see if more cases can be documented and if a reason for her choosing not to mate with the males can be found.

Social Media and Compiling Data

We all know that social media has changed the way much of the world interacts with each other and, as we saw a couple of years ago with the protests in Iran, it can put a human face on countries and events all over the world. It has also changed the way that human behavior can be looked at. While this article from CNN focuses on the when I want to take a quick look at the how.
Worried about when you might get dumped? Facebook knows.

That's according to a graphic making the rounds online that uses Facebook status updates to chart what time of year people are splitting up.

British journalist and graphic designer David McCandless, who specializes in showcasing data in visual ways, compiled the chart. He showed off the graphic at a TED conference last July in Oxford, England.

In the talk, McCandless said he and a colleague scraped 10,000 Facebook status updates for the phrases "breakup" and "broken up."
Facebook provides the ability to keep track of all of this data and to be able to see trends through times. So not only can we compile data from those who we can physically contact, which will typically lead to one country and possibly just one region of that country but from around the world. Now of course you run into the problem of people lying online or just not posting data but these are difficulties that you have in a typical study anyway and those outliers will tend to be more hidden when you have more data. This is interesting and if people continue to use this idea and developing studies who knows what future trends we might be able to see in the long run.

One last thing, don't be that asshole who breaks up with your significant other on Christmas come on people.

VOTE!!!!

This is a repost of this post from October 6th but I just wanted to make sure that everyone who hasn't voted does.

Coming up in November the U.S. is holding our annual elections. This year is as important as every year to make sure you get out and vote. Now some of you may be asking yourself, why is he posting this so early? Well the answer is quite simple, I know there are a lot of people out there who will be away from their permanent residents on election day due to being at school and what not. I wanted to remind all of these that there is a way to go about voting. One option is to declare your residency in the area where you are currently going to school but for many of you this just will not be possible for any number of reasons. The other option, and the one that inspired me to write this post, is the absentee ballot. Every state has an option to fill out an application form for an absentee ballot but you need to make sure that you do so shortly. I received my ballot in the mail on Monday and this will allow me to participate in the voting process even though I will be attending school over a thousand miles away. So no matter who you vote for or if you have to vote absentee make sure that you do.

UPDATE: It is too late to submit your absentee ballot but make sure you vote my absentee ballot has long since be submitted.

The Hockey League No One Wants To Be In

By now I am sure most people are aware of what is known as the hockey stick graph, the one showing a much lower temperature for the planet till the early 20th century and there has been a huge increase in temperature since. It is easy enough to pass of one line of evidence by saying correlation does not equal causation, and this is how science should work. But science also works by pulling together multiple lines of independent evidence in support of a hypothesis. Skeptical Science has a great post showing that the more famous hockey stick graph is not the only one showing this type of trend.
The original 1998 hockey stick by Mann, Bradley and Hughes didn't prove that humans are causing global warming. The evidence for man-made global warming lies in the multiple lines of empirical evidence finding human fingerprints throughout climate change. But the multitude of hockey sticks (or hockey league) do tell a story - humans have caused a profound disturbance to our climate system. To say "the hockey stick is broken" is to ignore the full body of evidence of hockey sticks throughout climate change.
The article is worth your attention as it shows that it is not just one but many lines of evidence that support the idea that we are in fact changing our own climate.
