When it comes to hearing, the left and right sides of the brain work together, mouse research shows

 "Using a novel microscope that enabled us to see both  hemispheres at the same time, we found that some of those connections are between the right and left brain hemispheres, allowing functional specialization. When the brain does not get the right inputs, for example in hearing loss, these brain connections are missing. This obviously is an issue if we hope to restore hearing at a later age."

Sexing the Canvas: Art and Gender MOOC

Image
  What do paintings tell us about sex? How is art gendered? In this course we will study some of the world’s most beloved pictures guided by expert curators and art historians who step outside of the square, bringing a gendered reading to the masterpieces contained in the magnificent collections that we have been lucky enough to bring to the Coursera platform. In this course you will learn how: * Gender and sexuality is an integral part of the production and reception of works of art * To increase your understanding of paintings through theories of gender and sexuality * To understand key terms from gender-related theories of art history and museology * To recognise the operation of what is termed ‘the gaze’ and how it works in relation to paintings * Ideas about gender and sexuality can productively be employed in theorising art curatorial practices * To take the initiative in relating theoretical ideas about gender and sexuality to the reading and display of art and visual cultu...

A revisited history of cacao domestication in pre-Columbian times revealed by archaeogenomic approaches

Image
  Abstract "Humans have a long history of transporting and trading plants, contributing to the evolution of domesticated plants.  Theobroma cacao  originated in the Neotropics from South America. However, little is known about its domestication and use in these regions. In this study, ceramic residues from a large sample of pre-Columbian cultures from South and Central America were analyzed using archaeogenomic and biochemical approaches. Here we show, for the first time, the widespread use of cacao in South America out of its native Amazonian area of origin, extending back 5000 years, likely supported by cultural interactions between the Amazon and the Pacific coast. We observed that strong genetic mixing between geographically distant cacao populations occurred as early as the middle Holocene, in South America, driven by humans, favoring the adaptation of  T. cacao  to new environments. This complex history of cacao domestication is the basis of today's cacao ...
