The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.

Q: Are you saying that because I prefer to date [whatever race], I’m a racist? There are many situations that might not be explicitly romantic, but are nonetheless a lot like a first date. In short, “beautiful people” receive a lot of the same built-in benefits in our society that white people do. Beauty is a cultural idea as much as a physical one, and the standard is of course set by the dominant culture. One interesting thing about Ok Cupid’s interface is that we allow people to select more than one race, so you can actually look at people who’ve combined “white” with another racial description. In fact it goes a long way towards undoing any bias against you.
On an individual level, a person can’t really control who turns them on — and almost everyone has a “type,” one way or another.
In 2011, a Swedish team found soft tissue and biomolecules in the bones of another creature from the time of the dinosaurs, a Mosasaur, which was a giant lizard that swam in shallow ocean waters.
Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded.
That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.
Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs. Mary Schweitzer, associate professor of marine, earth, and atmospheric sciences at North Carolina State University, surprised scientists in 2005 when she reported finding soft tissue in dinosaur bones.
Move one square to the left, and you see that they think Latinos are 1% above average, and so on.
The color is there to make the big trends easy to see. Ok Cupid users are certainly no more open-minded than they used to be. Here are the numbers for 2009 till now — view each graph below to move through time.
Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate.
After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings.
These, together with many other remarkable concordances between samples from different fossils, geographic regions and stratigraphic positions make random contamination as origin of the C-14 unlikely". She started a firestorm of controversy in 20 when she reported that she had sequenced proteins in the dinosaur bone.
