Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.Carbon dating is used to work out the age of organic material — in effect, any living thing.It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.The UNC Lineberger Comprehensive Cancer Center played matchmaker recently, hosting a scientific “speed-dating” event to match surgeons with engineers based on mutual interests in solving real-world medical problems.The event featured many of the surgeons that are part of the Department of Surgery faculty.Science in its original sense was a word for a type of knowledge rather than a specialized word for the pursuit of such knowledge.
While the classification of the material world by the ancient Indians and Greeks into air, earth, fire and water was more philosophical, medieval Middle Easterns used practical and experimental observation to classify materials.
We want to be the leaders.” Teams came up with ideas for studying how colon cancer spreads in the blood, for studying radiation as a first-line treatment for sarcoma, and a potential new method for delivering pain medication to wounds.
The competition was a cross-campus initiative of UNC Lineberger, the Joint UNC/NC State Department of Biomedical Engineering and University of North Carolina School of Medicine Department of Surgery.
The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.
