Bio-archaeologists pinpoint oldest Northern European human activity

16.12.2005


Scientists at the University of York used a ‘protein time capsule’ to confirm the earliest record of human activity in Northern Europe.



A team of bio-archaeologists from York were able to provide the final piece of scientific evidence which confirmed that primitive stone tools discovered in East Anglia dated back around 700,000 years – 200,000 years earlier than any other traces of human colonisation of northern latitudes.

Dr Kirsty Penkman and Dr Matthew Collins were part of an international team, headed by the Ancient Human Occupation of Britain (AHOB) project, which studied the worked flint flakes discovered two years ago in a cliff at Pakefield near Lowestoft, Suffolk.


After members of the international team used stratigraphy to indicate the likely age of the flints, the York scientists were called in to confirm the antiquity of the artefacts using a newly-refined technique of amino acid analysis. The technique measures the extent of deterioration of proteins in fossils found close to the flints - in this case, opercula, the tiny trap-doors that close a snail’s shell.

The results of the research are published in the latest edition of Nature today (Thursday 15 December 2005).

Dr Penkman, an Associate member of AHOB, said: “The amino acids were very securely contained in enclosed crystals of the opercula, unchanged by environmental factors other than normal internal protein degradation. In effect, they are a protein time capsule, enabling us to confirm the Pakefield opercula were significantly older than 500,000 years, the previous earliest date for humans north of the Alps.”

Dr Collins said: “The method relies upon measuring the products of decomposition, so we had to isolate a protein sample that was well protected and did not leak the products of decay.”

Dr Penkman added: "Helping to demonstrate the antiquity of the Pakefield site has been very exciting, and we are now trying to apply the same technique to more sites in Britain and overseas. A systematic survey will enable us to build a framework which records the extent of protein degradation in different sites, so that we can link the patchy terrestrial records of past climate change with the long continuous records from ice cores and marine sediments".

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
