Thousand-year-old vineyards discovered in Alava, Spain Posted: 23 Dec 2013 10:10 AM PST Zaballa (Iruña de Oca) was a medieval settlement abandoned in the 15th century. The building of a manor monastery at the heart of it undermined the organization of the village in the 10th century with the creation of a highly significant rent-seeking system; it was later turned into a veritable factory, a specialised estate in the hands of local lords who, under the auspices of the economic boom in towns like Vitoria-Gasteiz, tried to obtain the maximum profits possible. In the end, the "flight" of its settlers towards the towns caused it to be abandoned. Today archaeologists are endeavoring to reconstruct and salvage our rural heritage by studying deserted settlements like Zaballa.

Roles, responsibilities of patient navigators defined Posted: 23 Dec 2013 08:48 AM PST New research defines the roles and responsibilities of patient navigators. With the rapid growth of patient navigation, the paper seeks to develop a framework to describe similarities and differences across navigators and clarify their place in the health care system, leading to greater standardization of the profession.

Solitons in a crystal: New light source could serve in geo-navigation, search for Earth-like planets Posted: 23 Dec 2013 07:07 AM PST By creating an optical soliton in a microresonator, scientists have found a new light source that could serve in geo-navigation, telecommunications, spectroscopy and the hunt for new Earth-like planets.

Resistance makes waves Posted: 23 Dec 2013 07:07 AM PST Even physics can give pointers for energy saving. An international team is now in a position to provide materials scientists with tips for the development of high-temperature superconductors, in a bid to make them earn their name. The term is currently used to describe materials including ceramic cuprates, which lose their electrical resistance at significantly higher temperatures than conventional superconductors, but still well below the freezing point of water.

Getting excited helps with performance anxiety more than trying to calm down, study finds Posted: 23 Dec 2013 05:39 AM PST People who tell themselves to get excited rather than trying to relax can improve their performance during anxiety-inducing activities such as public speaking and math tests, according to a new study.

Motor excitability predicts working memory Posted: 23 Dec 2013 05:38 AM PST Humans with a high motor excitability have a better working memory than humans with a low excitability. By measuring the motor excitability, conclusions can be drawn as to the general cortical excitability – as well as to cognitive performance. Working memory allows the temporary storage of information such as memorizing a phone number for a short period of time. Studies in animals have shown that working memory processes among others depend on the excitability of neurons in the prefrontal cortex.
