You have carbon dating whale question interesting

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay.

One seemingly simple thing was resolved this week, as scientists finally put an age range on whale sharks by dating the slightly radioactive carbon isotope their bones collected after Cold War. Researchers used radiocarbon dating of eye proteins to determine the ages of 28 Greenland sharks, and estimated that one female was about years old. The former vertebrate record-holder was a bowhead whale estimated to be years old. As lead author Julius Nielsen, a marine biologist from the University of Copenhagen, put it: "We had our. Scientists were able to use carbon dating to find out how old whale sharks are. They took two shark skeletons - and studied the rings inside the bones of these skeletons to see how old the sharks.

Imagine science making it possible for sharks to live as people out living everything by using dog ageing for political reasons to proove all is wrong with only biblical means and doing all of this by picking baby noses in in parts of the sky with the most radiocarbon.?

Induce vomiting b. Gastric suction stomach pumping c. Kill the child. I never knew there was anything on earth that could live that long!! I wonder what else is down there.

This article is a perfect example of why people who cannot read, comprehend what they read, nor understand science should ever be allowed to comment on any article about science. If a set of individuals cannot comprehend what they read, this implies that they do read, and therefore can read.

question interesting

I found this article very interesting and informative. Would much rather read and learn about our own world rather than one I will never be able to visit. The most amazing part of this article is how awful people are to other people when the article had absolutely nothing to do with people in the first place.

Learn to read an article without becoming personally offended by everything or thinking that somehow every article, including articles about wild animals, are somehow politically motivated to attack you.

final, sorry, but

Reading severely damages your ignorance. You should try it and educate yourself. So my point is please leave these creatures alone.

Whale sharks (Rhincodon typus) are the largest living fish in the world, averaging about 32 feet (10 meters) Because carbon decays at a steady rate, the study authors were able to look at. Oct 03,   A formula to calculate how old a sample is by carbon dating is: t = [ ln (Nf/No) / ] x t1/2. t = [ ln (N f /N o) / ] x t 1/2. where ln is the natural logarithm, N f /N o is the percent of carbon in the sample compared to the amount in living tissue, and t 1/2 is the half-life of carbon (5, years). So, if you had a fossil that had 10 percent carbon compared to. Apr 07,   This isn't the first time carbon dating has been used to calculate the age of sharks, but the application to whale sharks is seen as a big deal because the animals are endangered.

Just imagine if dinosaurs were still living, how would you feel. Besides that, bionic is a thing you know, also information is needed in order to understand live itself, develop plans to protect the nature and sometimes information is gathered for the information itself.

Enjoyed it very much. Not always.

agree, useful idea

Maybe they did something similar. Sometimes when this happens they end up being used for scientific research. These are parasites that have uniquely evolved to live on the eye tissue of greenland sharks, the consequence of which results in the discoloration you see, and blindness. Lmao Trump gets brought into everything ppl r rediculouslife is what u make it y b miseravle anyways great article, very interesting.

confirm. was and

Some of these comments are unbelievable. Wow that is utterly amazing!

Radiometric dating / Carbon dating

What else lurks beneath the murky waters? By the wayyour book is great but scaring me lol. Not done yet. Just curious. No carbon daring their eye was how they estimated the age and then estimated that their growth was that for comparing birth size to more mature sharks.

Radiocarbon dating (also referred to as carbon dating or carbon dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in Apr 08,   The "time stamp" comes from a radioactive form of carbon that occurs naturally in low levels called carbon It's used in carbon dating of archaeological Whale sharks spend their days. Carbon dating definition is - the determination of the age of old material (such as an archaeological or paleontological specimen) by means of the content of carbon - Fox News, "Ancient whale bones unearthed beneath Edinburgh construction site," 20 June The carbon dating regulation, first.

I think this is amazing and so much to be learned from this study. Some of the comments and of course one must add something political, are ridiculous.

Are not carbon dating whale thank

Cant we jsut experience the report for what it is. Clearly the shark was released. Another picture shows a diver swimming with the sharks. Please let us enjoy the read without your personal need to espouse your views unrelated.

apologise, but

Do you know the only thing more important than your life? You seethings could alwsy be worseyou could have been born a Greenland SharKWhat a dreadful life!! What does that have to do with sharks and longevity? This is exactly the mentality Trump has adopted about science: Science vs politics.

many thanks for

Leave the politics out of science. You want a cure to every disease you acquire the same as any other liberal or conservative does. Ya gotta quit with that mindset for the sake of science. Geeze Karen. Teresa what does trump have to do with sharks and longevity?

Return carbon dating whale consider, that you

You must be a liberal! They study them and put them back, as they do for all.

are not right

Do you even know how to science?! At least read the article. Newser - Scientists have figured out that the world's biggest fish lives for a surprisingly long time, and the discovery comes courtesy of atomic bomb tests from decades ago.

Carbon dating whale

The fish is the enormous whale shark, and the study in Frontiers in Marine Science suggests they can live a century or more, reports the BBC. Researchers determined this in an unusual fashion: They measured the amount of carbon in the skeletal remains of an adult female shark.

consider, what

As New Atlas explains, carbon is a radioactive isotype, and all living creatures absorbed it during the Cold War testing of nuclear weapons. It's like a "chemical fingerprint," per Popular Mechanics.

Opinion you carbon dating whale pity, that now

Scientists know the decay rate of the isotope, and by measuring it in tandem with growth rings on the whale shark's vertebrae, they were able to calculate the animal's age. The rings alone are seen as unreliable. In this case, they concluded the shark was 50 years old.

But it was a relatively small one feet, far short of the footers swimming in the ocean-meaning it still had years to grow. This isn't the first time carbon dating has been used to calculate the age of sharks, but the application to whale sharks is seen as a big deal because the animals are endangered.
