Agriculture may have had many roots, DNA study suggests The skeletons of four ancient farmers have been found in Iran, and DNA tests indicate they have no genetic links to Aegeans, long thought to be the first farmers in Europe, which suggests that agriculture may have been developed more than once. DNA analysis of the […]
Everybody knows the force that is required to activate a light switch on a wall – a finger is enough. But how much force do you need to apply if the device was dramatically reduced to the “nanoscale world”, that is, how much force do you need to operate a “single-molecule switch”? This fundamental question […]

Cannabis use spread throughout Eurasia as Bronze Age dawned Ancient humans in both Asia and Europe started using cannabis as early as the end of the last ice age. Researchers say the use of cannabis intensified in East Asia around the beginning of the Bronze Age, then spread throughout Eurasia. New Scientist AI technique developed […]
In order to study new solid state magnetic properties appropiate new laboratory models are needed. In particular, there is a necessity for a substrate to investigate new forms of magnetic coupling with nanoscale ferromagnets and the exotic physics at the interface with semiconductor or superconductor materials. Now a team of researchers from DIPC and some […]
The stem cell research field shocked the scientific community back in 2006 thanks to Shinya Yamanaka, who found a way to obtain pluripotent stem cells from adult somatic cells . The recipe consisted of just four genes encoding for transcription factors allowing him to reprogram mouse fibroblasts into induced pluripotent stem cells (iPSCs). The “Yamanaka […]

Studies shed new light on Zika virus brain damage in infants Nearly 20% of babies infected with the Zika virus had normal head circumferences, which researchers said indicates a focus on microcephaly screening alone is too narrow, according to a study of about 1,500 newborns. Another study showed that brain tissues of infants with Zika […]
Autism is a highly prevalent spectrum disorder of the neurodevelopment. It is characterized by impaired social interaction, alterations in verbal and non-verbal communication, and restricted and repetitive behaviors. Considering these main differences, it had been difficult to have good animal models since these interactions were initially defined for humans but scientists are nowadays developing different […]
It is interesting how we describe social rejections – betrayal, exclusion from a group or a break-up from a romantic relationship are good examples: “he was cruel with me and it was painful”, “I suffered a lot during the divorce”, etc. Why we describe them as painful situations where there is no physical contact? If […]
