When paleontologist Mary Schweitzer found soft tissue in a Tyrannosaurus rex fossil , her discovery raised an obvious question — how the tissue could have survived so long? The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains , decomposes. Only hard parts, like bones and teeth, can become fossils. But for some people, the discovery raised a different question.

The age of the earth is a central issue in creation -evolution discussions, because a young earth would not permit enough time for evolution to occur, and an old earth would contradict a literal reading of the Bible account of creation. The belief in an old earth is based on conventional dates for geological periods, which are in the hundreds of millions of years range, and are obtained by isotopic dating methods. Standard isotopic radiometric dating techniques typically yield such dates on fossil-bearing strata.
There are, however, numerous disagreements between dates produced by different isotopic dating methods, and there are many cases where the dates obtained are very different from the expected ones.
To exemplify the MS formalization of “softer” subjects, let us recount the story of the introduction of agriculture in Europe (New Scientist, ). Radiocarbon dating.
By Aviva Rutkin. ONE Saturday night last year, 11 people went looking for love. Like countless speed daters before them, they met in a room draped with curtains, the lights on low. In one hand they held traditional glasses of bubbly , but in the other were sheets of paper they had filled with their personal data.
This twist on speed-dating was part of an experiment run by a team at Newcastle University in the UK. They wanted to know what would happen in a world where instead of vetting potential dates by their artfully posed selfies or carefully crafted dating-site profiles, we looked at data gathered by their computers and phones. Elsden and his colleagues want to explore other ways we can use data that gets collected as we go about our modern lives.
The team recruited their speed daters on social media and via posters around their university campus. A week before the event, the participants were sent a form to fill out. It asked for a host of specific numbers: shoe size, the farthest distance they had travelled from home, the earliest and latest times of day they had sent an email in the past month, their heart rate as they filled out the form.
It also left blank spaces for people to add whatever data they wanted.

By Chelsea Whyte. They found that women receive more messages than men, and most of the messages sent on the service go to only a small fraction of users. The most popular person in the study was a year-old woman in New York who received messages during the month-long study period. For men, desirability peaked at around 50 years old, while for women it peaked at 18 and dropped steadily with age.

Absolute dating also known as radiometric dating is based by the measurement of the content of specific radioactive isotopes of which the “half time” is known. Half time is the time needed for half of a given quantity of an isotope to decay in its byproducts. Comparing the quantity of the parent form and the byproduct will give a numerical value for the age of the material containing such isotopes. Example include carbonnitrogen, uranium-led, uranium-thorium.
Relative dating instead allows for identifying the sequential order of geological events one relative to the other. This is based on the concept that, in a normal depositionary sequence, the deepest layers are also the oldest. Absolute dating is actually a misnomer. The absolute dating is based on calculation of half life. The calculation are based on the percentages of parent, and daughter elements. These calculations are based on geological assumptions of uniform process, the lack of erosion of either the parent or daughter elements.
The results are often determined by the estimates of the presumed age of the strata based on relative ages. The age determined by relative dating is based on the rules of super imposition and the presumed age of strata based on fossils. The deeper strata is presumed to be older than strata above.
How does absolute dating differ from relative dating?
In , Rashied Amini was just another engineer in love. Unfortunately, his girlfriend had not come to the same conclusion. The numbers did not add up the same way for her. I bet I could build this. Thus Nanaya, a love prediction algorithm , was born. It was conjured in the hopes that love would listen to numbers. Amini started off with the basics, working part time on what would become a full-fledged dating-app startup.
His work as a rocket scientist gave him a framework. Romance, he figured, simply presented a different set of uncertainties.

Being on the shelf is only a problem if your shelf is dull. In fact, the older you get, the more interesting your shelf is likely to become and the harder it is to be coaxed off. And we are extending our own shelf-life everyday by staying fitter, healthier and more attractive for longer.
Women are no longer crying into their Chardonnay. Singles are more likely to be playing capoeira; dining at secret supper clubs; running with the Good Gym or digging up their home-grown kale. Which is why dating is such a problem. Why would you want to spend an excruciating hour getting to know a complete stranger when you could be enjoying ukulele karaoke with your mates or learning to make gin?

After a grueling arms race exposed to the never ending onslaught of invaders, our immune system has developed techniques to ensure clearance of infected cells. These adaptive immune cells use certain “markers” to identify health cells from intruders. I will be discussing the “yin and yang” effects of immune cells killing infected cells by varying concentrations of these “markers”.

But Marvin Rowe is no nut. The process is important because, unlike other methods of radiocarbon dating that destroy the sample being tested, LEPRS preserves it. It also works on tiny samples — even a flake of ink or paint — and is considered a more accurate means of dating. Because a lot of that part of New Mexico is private property or under land grants, such finds as the one in Coyote Canyon are rare, she said.
The tooth was found at a site near Coyote Creek north of Mora. The machine is used to date artifacts without damaging to the sample. The achievement has been decades in the making. Blinman adds that, under the best of circumstances, standard radiocarbon dating requires 30 milligrams of carbon. He says much of what he learned was by trial and error.
Traditional carbon dating estimates age based on content of carbon C , a naturally occurring, radioactive form of carbon, and requires destruction of an object. A piece of an organic object — a bone fragment or weaving, for example — is washed with acid at high temperature to remove impurities and then burned in a chamber. The carbon dioxide gas produced is run through an accelerator mass spectrometer, which measures the decay of radioactive carbon 14 — the more the carbon 14 has decayed, the older the object is.
‘Perhaps the most important isotope’: how carbon-14 revolutionised science
Fossilized roots dating back to million years ago, in Cairo, New York. The researchers say the new site is evidence that forests developed 2 to 3 million years earlier than previously thought. The findings were published recently in the journal Current Biology. The site, located in the town of Cairo, New York, has three unique root systems — evidence that ancient forests were comprised of several different tree species.
Dating past events can be difficult. Archaeologists often rely on carbon dating, which can be used on organic samples, but this technology usually gives a broad date range. Five years ago, a discovery was made that promises to change all that, at least in some cases. Global spikes in carbon concentration which occur sporadically may help us pinpoint historic events to a single year. Unfortunately, the cause of the spikes may also create chaos for our civilization.
He uses the carbon method to date organic objects up to around 40, years of age. He works primarily on techniques to improve the accuracy of carbon dating, such as Bayesian modelling, a mathematical method which allows the date range to be narrowed. In the upper atmosphere, cosmic particles hit gaseous atoms, causing them to release neutrons that in turn are captured by nitrogen and transformed into the radioactive carbon isotope.
Plants absorb carbon dioxide from the atmosphere. This carbon dioxide includes a tiny amount of carbon, so when the plant — or the animal that ate the plant — dies, the carbon uptake stops and the carbon slowly decays. Every 5, years, half of the carbon has gone. Therefore, the carbon concentration tells you how old the object animal, vegetable or even mineral is. However, production rates of carbon in the atmosphere can change, says Dee.
