The transition from hunter-gatherer to sedentary farming 10,000 years ago occurred in multiple neighbouring but genetically distinct populations according to research by an international team including UCL.

"It had been widely assumed that these first farmers were from a single, genetically homogeneous population. However, we've found that there were deep genetic differences in these early farming populations, indicating very distinct ancestries," said corresponding author Dr Garrett Hellenthal, UCL Genetics.

Athens, Ga. - An international team of ecologists has identified the bat species with the greatest potential to harbor filoviruses--a family that includes Ebola virus. Writing in PLOS Neglected Tropical Diseases, they suggest that areas where many of these species overlap, notably in Southeast Asia, should be targeted for disease surveillance and virus discovery efforts.

EAST LANSING, Mich. -- Fathers play a surprisingly large role in their children's development, from language and cognitive growth in toddlerhood to social skills in fifth grade, according to new findings from Michigan State University scholars.

The research provides some of the most conclusive evidence to date of fathers' importance to children's outcomes and reinforces the idea that early childhood programs such as Head Start should focus on the whole family, including mother and father alike. The findings are published online in two academic journals, Early Childhood Research Quarterly and Infant and Child Development.

It is common knowledge that salt consists of the cation sodium and the anion chloride. However, the substance used to season food has been a cause of great concern to farmers for some time now: In times of climate change, more and more agricultural areas have to be irrigated. This inevitably leads to the increasing salinisation of soils, that is the accumulation of sodium and chloride ions.

Unlike classical crystals, quasicrystals do not comprise periodic units, even though they do have a superordinate structure. The formation of the fascinating mosaics that they produce is barely understood. In the context of an international collaborative effort, researchers at the Technical University of Munich (TUM) have now presented a methodology that allows the production of two-dimensional quasicrystals from metal-organic networks, opening the door to the development of promising new materials.

Johns Hopkins University researchers are the first to glimpse the human brain making a purely voluntary decision to act.

Unlike most brain studies where scientists watch as people respond to cues or commands, Johns Hopkins researchers found a way to observe people's brain activity as they made choices entirely on their own. The findings, which pinpoint the parts of the brain involved in decision-making and action, are now online, and due to appear in a special October issue of the journal Attention, Perception, & Psychophysics.
