Traces of volcanic ash originating from islandic volcanoes have been found in the sediments of Laker Tiefer See in the Nossentiner-Schwinzer Heide natural park in Mecklenburg-Vorpommern.

An international team of geoscientists identified traces of in total eight volcanic eruptions on Island of which six could be precisely identified. The oldest eruption occurred 11,400 years ago and the youngest, from 1875, has been described in historical documents.

Generally, organic conductors has disorder structures so charge transfers from one place with high conductivity to another place with high conductivity. In such occasions, Coulomb blockade of charge transport takes place. It was thought that Coulomb blockade took place in low dimensional aggregates of inorganic particulates only at very low temperatures.

Imagine a new type of tyres whose structure has been designed to have greater adhesion on the road. Quite a timely discussion during the long winter nights. French physicists have now developed a model to study the importance of adhesion in establishing contact between two patterned, yet elastic, surfaces. Nature is full of examples of amazing adjustable adhesion power, like the feet of geckos, covered in multiple hairs of decreasing size. Until now, most experimental and theoretical studies have only focused on the elastic deformation of surfaces, neglecting the adhesion forces between such surfaces.

No one wants to knowingly buy products made with child labor or that harm the environment and that may be why few people want to know if their favorite products were made ethically. Even beyond that, people really don't like those good people who make the effort to seek out ethically made goods - because, like going on a cleanse, no one ever did so quietly.

Over the past decade, neuroimaging studies, basically taking snapshots of neural circuitry as behavior occurs and mapping cause to effect, have sought to identify components of a neural circuit that operates across various domains of creativity. A new paper suggests, however, that creativity cannot be fully explained in terms of the activation or deactivation of a fixed network of brain regions. Rather, the scholars say, when creative acts engage brain areas involved in emotional expression, activity in these regions strongly influences which parts of the brain's creativity network are activated, and to what extent.

Certain threats -- such as starvation or an attack by enemies -- turn on genes in carpenter ants that change their behavior in ways that help their colony survive, according to a study co-authored by NYU Langone researchers and published in the Jan. 1, 2016, edition of the journal Science. With related molecular pathways present in humans, the study may provide insights into mechanisms behind behavioral disorders.

Specifically, the research team found that compounds known to block the action of a group of enzymes, histone deacetylases (HDACs), activated genes that made one kind of carpenter ant worker behave like another, and without changing the instructions encoded in their genes.
