Vibeke Martens Hans Renssen. Climate changes on Greenland are currently threatening areas of archaeological importance that have not yet been excavated. Therefore, The National Museums of Denmark and Greenland have started several projects where decomposing wooden artifacts and bones will help identify the areas, which are most seriously threatened — and save them.
The remains of a rich pearl fishing industry in Qatar were abandoned for centuries until archaeologists recently unearthed them.

Variations between seasons may be erased in , and Norway will have a climate like today's southern France. Carbon emissions from Arctic soils threaten to greatly accelerate climate change by A particular type of wax that accumulates on the surface of plant root cells is vital for their nutrient balance, new study shows.
The results truly challenge the way we think about plant growth and plant root adaptations. Computing society needs to promote more gender equity and better ways at working together.
We present our experiences on trying to do so. A small town in northern Iceland has gone almost CO2-neutral. Researchers went there to find out how they did it and what we can learn from them. Drug-resistant infections are increasing globally. One new member of the superbug family has already caused severe illness in hospitalized patients. Here is what you need to know. Today CO2 is removed from industry by using molecules called amines, which react with CO2. DTU has developed a new method using molecules from the human blood to remove CO2.

The new technology could help prevent climate change. Babies who were just 10 months old and who later received a diagnosis of Autism Spectrum Disorder took less initiative than other children to communicate with adults. New research suggests that long-term stress is transmitted from human to dog. However, scientists from Syddansk Universitet are on the case using statistics to save endangered animals. A neurotransmitter in the brain affects whether we gain or lose weight, a new study in mice suggests. In a democratic society, we need to teach children to become critically aware and understand how data processing and digital technologies really work.
Biological insecticides are naturally derived pesticides that represent an environmentally friendly alternative to many of the existing pesticides used in agriculture.
More recently, spider toxins have been employed to develop highly specific pest control agents that have been introduced to the market. Universities that offer courses in archeometry offer these courses frequently as free choice for archeology students and these courses contain mainly a nonscientific overview over the possibilities that different scientific analyses offer to them.
Archaeological science can be divided into the following areas: . Techniques such as lithic analysis , archaeometallurgy , paleoethnobotany , palynology and zooarchaeology also form sub-disciplines of archaeological science. Archaeological science has particular value when it can provide absolute dates for archaeological strata and artifacts. Some of the most important dating techniques include:. Another important subdiscipline of archaeometry is the study of artifacts. Archaeometrists have used a variety of methods to analyze artifacts, either to determine more about their composition, or to determine their provenance.
These techniques include:. Lead , strontium and oxygen isotope analysis can also test human remains to estimate the diets and even the birthplaces of a study's subjects. Provenance analysis has the potential to determine the original source of the materials used, for example, to make a particular artifact. This can show how far the artifact has traveled and can indicate the existence of systems of exchange. Archaeometry has greatly influenced modern archaeology. Archaeologists can obtain significant additional data and information using these techniques, and archaeometry has the potential to revise the understanding of the past.
For example, the "second radiocarbon revolution " significantly re-dated European prehistory in the s, compared to the "first radiocarbon revolution" from Archaeometry is an important tool in finding potential dig sites. The use of remote sensing has enabled archaeologists to identify many more archaeological sites than they could have otherwise.

The use of aerial photography including satellite imagery and Lidar remains the most widespread remote-sensing technique. Ground-based geophysical surveys often help to identify and map archaeological features within identified sites.
