Space movies regularly dispatch characters through an explosively decompressed airlock. But how likely is such a rapid ejection, taking into account the victim's location in the airlock and its volume. Assuming they are wearing a space suit, what is the best way to avoid expulsion, apart from grabbing something solid. We sweat to cool our bodies by evaporation, but when we wipe the sweat away — a natural reaction in humans — are we defeating that function and making ourselves hotter. Do we also hasten dehydration by making our bodies sweat more, to replace what we've wiped away. In other words, should we just leave the sweat to do its job?.

The carbon clock is getting reset. 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. The technique hinges on carbon, 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 from the atmosphere when they are alive. By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon decay can be worked out, thereby giving an age for the specimen in question. But that assumes that the amount of carbon in the atmosphere was constant — any variation would speed up or slow down the clock.

April 24, - The question was resolved by the study of tree rings: A key concept in interpreting radiocarbon dates is archaeological association: Once produced, the 14 C quickly combines with the oxygen in the atmosphere to form carbon dioxide CO 2. Subscribe now for unlimited access to online articles. There are a number of outlines of the skeletons in the standard literature but only one fleshed out reconstruction that I have ever seen. This provides a value for the background radiation, which must be subtracted from the measured activity of the sample being dated to get the activity attributable solely to that sample's 14 C. This has been described as a "second radiocarbon revolution", and with regard to British prehistory, archaeologist Richard Atkinson has characterized the impact of radiocarbon dating as "radical

Carbondated dinosaur bones are less than 40, years old. Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed. Carbon C dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22, to 39, years old. 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.

Danish Stone Age settlements may turn out to be hundreds, perhaps thousands, of years younger than we thought. A physicist from Aarhus University has together with archaeologists at the Gottorp Castle Museum in Northern Germany made a startling discovery: In sites where people ate fish, we might see errors in the Carbon dating of clay vessels. This is due to the fact that fish contain less of the radioactive substance Carbon 14 if they have lived in hard water.

There was also a historical test of a piece of linen performed in by Willard Libbythe inventor of the dating method. One of the earliest carbon dating tests was carried out on November 14, InRobert Eisenman and Philip R. Davies made a request to date a number of scrolls, which led to a series of tests carried out in Zurich on samples from fourteen scrolls.

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 14 Ca radioactive isotope of carbon. The method was developed by Willard Libby in the late s and soon became a standard tool for archaeologists. Libby received the Nobel Prize in Chemistry for his work in The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxidewhich 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 from that point onwards the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay.
