New Dinosaur Species Found in India
By RAMOLA TALWAR BADAM, Associated Press Writer
BOMBAY, India - U.S. and Indian scientists said Wednesday they have discovered a new carnivorous dinosaur species in India after finding bones in the western part of the country.
The new dinosaur species was named Rajasaurus narmadensis, or "Regal reptile from the Narmada," after the Narmada River region where the bones were found.
The dinosaurs were between 25-30 feet long, had a horn above their skulls, were relatively heavy and walked on two legs, scientists said. They preyed on long-necked herbivorous dinosaurs on the Indian subcontinent during the Cretaceous Period at the end of the dinosaur age, 65 million years ago.
"It's fabulous to be able to see this dinosaur which lived as the age of dinosaurs came to a close," said Paul Sereno, a paleontologist at the University of Chicago. "It was a significant predator that was related to species on continental Africa, Madagascar and South America."
Working with Indian scientists, Sereno and paleontologist Jeff Wilson of the University of Michigan reconstructed the dinosaur skull in a project funded partly by the National Geographic (news - web sites) Society.
A model of the assembled skull was presented Wednesday by the American scientists to their counterparts from Punjab University in northern India and the Geological Survey of India during a Bombay news conference.
Scientists said they hope the discovery will help explain the extinction of the dinosaurs and the shifting of the continents — how India separated from Africa, Madagascar, Australia and Antarctica and collided with Asia.
The dinosaur bones were discovered during the past 18 years by Indian scientists Suresh Srivastava of the Geological Survey of India and Ashok Sahni, a paleontologist at Punjab University.
When the bones were examined, "we realized we had a partial skeleton of an undiscovered species," Sereno said.
The scientists said they believe the Rajasaurus roamed the Southern Hemisphere land masses of present-day Madagascar, Africa and South America.
"People don't realize dinosaurs are the only large-bodied animal that lived, evolved and died at a time when all continents were united," Sereno said.
The cause of the dinosaurs' extinction is still debated by scientists. The Rajasaurus discovery may provide crucial clues, Sereno said.
India has seen quite a few paleontological discoveries recently.
In 1997, villagers discovered about 300 fossilized dinosaur eggs in Pisdura, 440 miles northeast of Bombay, that Indian scientists said were laid by four-legged, long-necked vegetarian creatures.
Indian scientists said the dinosaur embryos in the eggs may have suffocated during volcanic eruptions.

MRI is our livelihood. Ernst and Lauterbur tend to get the credit around here, although it's a controversy we don't give a rat's whiskers about.

History of MRI
Interestingly, Dr Isidor Rabi, an American physicist who was awarded the Nobel Prize for Physics in 1944 for his invention of the atomic and molecular beam magnetic resonance method of observing atomic spectra, came across the NMR experiment in the late 1930's but considered it to be an artefact of his apparatus and disregarded its importance. During the 50's and 60's NMR spectroscopy became a widely used technique for the non-destructive analysis of small samples. Many of its applications were at the microscopic level using small (a few centimetres) bore high field magnets. In the late 60's and early 70's Raymond Damadian, an American medical doctor at the State University of New York in Brooklyn, demonstrated that a NMR tissue parameter (termed T1 relaxation time) of tumour samples, measured in vitro, was significantly higher than normal tissue. ...
Although not confirmed by other workers, Damadian intended to use this and other NMR tissue parameters not for imaging but for tissue characterisation (i.e., separating benign from malignant tissue). This has remained the Holy Grail of NMR yet to be achieved due mainly to the heterogeneity of tissue. Damadian is a controversial figure in NMR circles not least for his exuberant behaviour at conferences. Although criticism has been levelled at his scientific acumen it should not overshadow the fact that his description of relaxation time changes in cancer tissue was one of the main impetuses for the introduction of NMR into medicine. On the 16th March 1973 a short paper was published in Nature entitled "Image formation by induced local interaction; examples employing magnetic resonance". The author was Paul Lauterbur, a Professor of Chemistry at the State University of New York at Stony Brook.

Damadian applied Ernst's T1 and T2 weighting to human imaging while Lauterbur applied CT reconstruction techniques. Both are used today.

Was just demonstrating that Damadian was not just "some crank". That's all.
To: Nebullis
Welcome back! I hope you had a great time on your vacation!
To: Nebullis
Welcome back Nebullis.
Leaving on a little vacation my self tomorrow.
A little homeschool astronomy, a little flyfishing, a little camping, a little writing, it will be nice to be away from it all for 5 days and 4 nights.
So glad to have you back, and see you later!! LOL
Won't be leaving til tomorrow, but am getting all the gear ready.
Welcome back.

Was just demonstrating that Damadian was not just "some crank". He's not just "some crank", he's a big crank! An opportunist, really, who nonetheless played an important, if not pivotal, role in the invention of MRI.
To: Ichneumon
So I've got a proposal for you: How about if we spend some time focusing specifically on the "young earth evidences" you've just presented? We'll all examine them in depth, and see if we can come to some agreements about whether they really hold up or not when scrutinized, and why. During the process I hope you may learn some things about how scientists validate or invalidate certain arguments, and how evidence is evaluated.
You all have every right to discuss whatever you want. I you want to discuss just young earth evidences, then go for it. I'm not going to agree to limit discussion to whether or not the arguments I presented from AiG are true or false though because that is off the subject of this thread. I started the discussion, I think in post 4, by questioning the dating of the new dinosaur find. I believe all evolutionary dating models are incorrect. So, to limit me to the red hering of one particular post of mine ignores the purpose of the thread. Still, your own personal condescension in this post aside (I hope you may learn something), you may discuss whatever you wish.
Also, would you be willing to accept the idea that if (repeat, if) all or most of your evidences can be shown to be based on misconceptions or invalid reasoning, then perhaps creationist sources might not be as reliable or as good at science as you currently believe?
No, I do not accept the idea. The evolutionists on this thread have outright rejected any creationist resource I have posted. At least once, I was asked to post from something other than the two main creation website AiG and ICR, inferring that no good science is found at either. To accept your proposal would be to back down to bullying. Some creationists are better than others (as I have stated). Dr. David Menton is visibly more qualified to speak on issues than say Carl Baugh. I do not claim equal authority for each creationist or for each creationist article or argument. I will not succumb to the idea that creationism is just bad science, particularly from a group of people who are so attached to a theory that virtually no level of evidence would cause them to question it in the slightest. In other words, may these be used as a "quality check" for creationist (or at least AiG) arguments, in the same way that if you randomly sample products off an assembly line and they all test successfully, it gives confidence that the rest of the production run are likely to be good too, whereas if the random samples fail the quality checks, it implies that something's probably wrong with most or all of the rest of the batch?
For the reasons stated above, no sir. Thanks, but no thanks.

Thanks, All!
We had a great time sailing, fishing, etc. We were all blissfully happy.

The patent is for what? Is the word imaging in the patent?
Damadian discovered that tumors have a different NMR relaxation time from normal tissue. The discovery had nothing to do with imaging. Imaging is what the I in MRI stands for.
To: Nebullis
Well, the Supreme Court agreed with the "crank" over GE, and his patent was before the 1973 paper> You may not like him personally and he may be a bit eccentric. I don't know the man. But is not someone without claim to the technology as was inferred in earlier posts.
To: DittoJed2; Ichneumon
I thought it was a great idea Ichneumon.
He obviously does not want to actually learn anything, he just wants to toss his red herrings and strawmen out at us and hope that he can overwhelm us with crap.
This is a typical creationist tactic, you have seen the debates between creationists and evolutionists.
The creationist throws so much garbage out there, that the evolutionist has NO chance to refute an 1/8 of it, and when the debate is over it looks like the creationist won, because he overwhelmed his opponent with crap.
It's pretty typical, but it was a nice try though.
His response was NOT unexpected, but it really was a nice try.

Roland Gangloff's been there since 1987 and he's not seeing what the sculptor is seeing.

The patent office called it a BETA 3000 NMR SCANNING DEVICE
http://www.uspto.gov/web/offices/pac/dapp/opla/term/156.html If you click on the patent number, it confirms the patent was granted in 1974. If he filed in 1972, that means he had a scanning device in place prior to 1973. I am willing to concede that there should be shared contribution to the technology involved and that several folks apparently were doing similar research at one time. Just don't dismiss this scientist as a "crank". He is worthy of some respect for his contributions. 1977 was when he built the MRI scanner. It is within the realm of probability that he indeed did have MRI technology prior to 1973.

As I mentioned earlier, I do wish you would stop calling me a "he".

When Lauterbur left SUNY Stony Brook, I was hired as his replacement. Way cool!
