Carbon 4 dating
Creating a web series just proves - we're not dead yet!
Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.
The results showed that Ötzi died over 5000 years ago, sometime between 33 BC. It is found in the air in carbon dioxide molecules.
The amount of carbon-14 in the air has stayed the same for thousands of years.
Dwindling clientele and new smoking ordinances have forced veteran bar-owner Murray to make a tough decision: it's time to close the bar. It's the first episodic story telling about real things that happen to real people as we get older.
However, Murray's hopes for a quiet closing are ... So many things I can relate to shown in a naturally comedic way. Age happens - and let's be real, it's funny.
Patients often ask oncologists how long a cancer has been present before causing symptoms or spreading to other organs.
The evolutionary trajectory of cancers can be defined using phylogenetic approaches but lack of chronological references makes dating the exact onset of tumours very challenging.
Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.We used a Bayesian phylogenomic approach, which accounts for possible dynamic changes in mutational rate, to reconstruct the phylogenetic tree and effectively 'carbon date' the malignant progression.The primary colon cancer emerged between 5 and 8 years before the clinical diagnosis.There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.Once an organism dies, it stops taking in carbon-14.
