In the news: "Beer Tastes Intoxicating" by Sabrina Richards The Scientist April 15, 2013 BT2725 Illustration of the behavior of neurotransmitters in a synapse between two neurons. Neurotransmitters are endogenous chemicals that transmit signals from a neuron to a target cell across a synapse. In response to an electrical signal in the transmitting neuron, vesicles containing neurotransmitters fuse with the cell wall allowing the neurotransmitters to enter the synapse. They move toward the receiving neuron and attach themselves to receptors (green), relaying the message. Extra neurotransmitters migrate back to the transmitting cell via reuptake transporters.

In the news: "Francis Crick's DNA letter to his son sells at auction for a record $6 million" by Alan Boyle NBC News April 10, 2013 P4437 : DNA double helix | Science Source Beta DNA. Computer representation of a segment of the beta form of the molecule Deoxyribonucleic Acid (DNA). This molecule contains all inherited instructions necessary for the development of a living organism. Atoms are shown as spheres. The DNA molecule is composed of two strands of atoms twisted into a helical shape. Each strand consists of an outer sugar-phosphate backbone (gold) from which the bases project inwardly (silver). The bases are thus paired in a complementary fashion like rungs on a ladder, making up the genetic code. This code is divided into segments called genes. DNA is also the vehicle of genetic inheritance between different generations. Credit: Kenneth Eward / BioGrafx / Science Source

In the news: "Bigger not always better for penis size" by Regina Nuzzo nature.com April 8, 2013 BF9389 This anonymous Persian anatomical illustration (Iran or Pakistan, ca. 1680-1750) depicts a man with his abdomen and chest opened to reveal the internal organs. In his right hand, he holds a second set of genitalia, and there is a sketch of the liver and gallbladder in the upper left corner. The artistic conventions employed in the production of this illustration indicate Western India as a place of production. The 16th- to 18th-century European convention of picturing partially dissected bodies as if they were alive, offering up parts of their own body for further inspection, can be seen here transferred to the Indian subcontinent. The anatomy of the exposed organs reflects indigenous Indian concepts as well as some medieval Galenic anatomy. This is one of six anonymous anatomical drawings on folia 554-559 at the end of a volume containing Tibb al-Akbar (Akbar&…

In the news: "Obama's Plan to Explore the Brain: A 'Most Audacious Project'" by Jon Hamilton  NPR April 2, 2013 SD3731 Brain pathways. Coloured 3-dimensional magnetic resonance imaging (MRI) scan of the white matter pathways of the brain, side view. White matter is composed of myelin-coated nerve cell fibres that carry information between nerve cells in the cerebrum of the brain (top half of image) and the brain stem (bottom centre). This image was created by an MRI scanner sensitised to the movement of water around the brain. Blue represents neural pathways from the top to the bottom of the brain, green represents pathways from the front (left) to the back (right), and red shows pathways between the right and left hemispheres of the brain.
