VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain
...ong-term memory and learning, including that which occurs with addiction to alcohol or other drugs, Miles said. In the study, approximately 400 genes were identified as alcohol regulated in at least one brain region of either mouse strain. According to Miles, most of these genes showed regulation in only o...Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

...rosclerosis, known as "hardening of the arteries," occurs when the inside walls of an artery become thicker and less elastic. This narrows the space for blood flow and can lead to angina and heart attacks in some people. Fatty buildups occur on the inner lining of an artery and gradually thicken into a pla...No relief for Pacific Northwest drought

Moreover, different kinds of rewards (in this case, the "rush" of romantic love, compared with the pleasing experience of looking at a pretty or handsome face) is also lateralized.
