Could An Earthquake Be Responsible For The Image On The Shroud Of Turin?
2014-02-12 09:49:22

Springer Neutron radiation caused by 33 A.D. earthquake could have led to "wrong" 1988 radiocarbon dating of Shroud, suggest researchers An earthquake in Old Jerusalem might be behind the famous image of the Shroud of Turin, says a group of researchers led by Alberto Carpinteri of the Politecnico di Torino in Italy in an article published in Springer's journal Meccanica. They believe that neutron radiation caused by an earthquake could have induced the image of a crucified man - which...

For the first time a long temperature reconstruction on the basis of stable carbon isotopes in tree rings has been achieved for the eastern Mediterranean. An exactly dated time series of almost 900 year length was established, exhibiting the medieval warm period, the little ice age between the 16th and 19th century as well as the transition into the modern warm phase. Moreover, Ingo Heinrich from the GFZ German Research Centre for Geosciences and colleagues revealed that the modern warming...

3 billion-year-old Rocks Contain Microfossils Of Plankton
2013-06-06 21:18:25

Penn State Spindle-shaped inclusions in 3 billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to an international team of researchers. "It is surprising to have large, potentially complex fossils that far back," said Christopher H. House, professor of geosciences, Penn State, and lead author. However, the researchers not only showed that these inclusions in the rocks were biological in origin, but also...

New research in The FASEB Journal, based on carbon-14 dating, shows that despite repeated high-impact loading, the Achilles tendon is not renewed, but stays the same throughout adult life Notorious among athletes and trainers as career killers, Achilles tendon injuries are among the most devastating. Now, by carbon testing tissues exposed to nuclear fallout in post WWII tests, scientists have learned why: Like our teeth and the lenses in our eyes, the Achilles tendon is a tissue that does...

Radio Carbon Dating Improved With Sediment Measurementss
2012-10-19 13:02:37

April Flowers for redOrbit.com - Your Universe Online A research team from Oxford University's Radiocarbon Accelerator Unit has found a more accurate benchmark for dating materials, especially for older objects, from a series of radiocarbon measurements from Japan's Lake Suigetsu. As far back as 1993, researchers realized sediment cores from Lake Suigetsu would be useful for radiocarbon dating. However, the initial efforts encountered technical problems. The current team extracted...

Cold Cases Heat Up To Identify Remains Through Lawrence Livermore Approach
2012-10-10 16:01:46

In an effort to identify the thousands of John/Jane Doe cold cases in the United States, a Lawrence Livermore National Laboratory researcher and a team of international collaborators have found a multidisciplinary approach to identifying the remains of missing persons. Using "bomb pulse" radiocarbon analysis developed at Lawrence Livermore, combined with recently developed anthropological analysis and forensic DNA techniques, the researchers were able to identify the remains of a missing...

Ancient Carbon Resurfacing In Lakes
2012-10-05 08:04:08

April Flowers for redOrbit.com - Your Universe Online A new study is challenging current models of long-term carbon storage in lakes and rivers by revealing that a significant amount of carbon released into the atmosphere from lakes and rivers in Southern Quebec, Canada is approximately 1,000 to 3,000 years old. Current models and previous studies have shown there to be a tight coupling between the terrestrial and aquatic environment. So tight, in fact, that they expect aquatic bacteria...

'Faster-Ticking Clock' Indicates Early Solar System May Have Evolved Faster Than We Think
2012-05-02 07:00:54

Our solar system is four and a half billion years old, but its formation may have occurred over a shorter period of time than we previously thought, says an international team of researchers from the Hebrew University of Jerusalem and universities and laboratories in the US and Japan. Establishing chronologies of past events or determining ages of objects require having clocks that tick at different paces, according to how far back one looks. Nuclear clocks, used for dating, are based on...

Individual atoms of a certain chemical element can be very stubborn when it comes to separation, mainly because techniques rely on a difference in chemical and physical properties – atoms are almost identical in both regards. However, if you peer closely enough into the atoms, there are subtle differences that can have very big effects. These "different" atoms, called isotopes, are heavily relied on in areas of medicine and nuclear energy and now researchers have proposed a novel way...

Rising CO2 Levels At End Of Ice Age Not Linked To Pacific Ocean
2011-10-03 12:56:29

At the end of the last Ice Age, atmospheric carbon dioxide levels rose rapidly as the planet warmed; scientists have long hypothesized that the source was CO2 released from the deep ocean. But a new study using detailed radiocarbon dating of foraminifera found in a sediment core from the Gorda Ridge off Oregon reveals that the Northeast Pacific was not an important reservoir of carbon during glacial times. The finding may send scientists back to the proverbial drawing board looking for...


Word of the Day
jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
