Cocaine and the teen brain: New insights into addiction
22.02.2012 3:26 12 views 0 comments
From:
feeds.sciencedaily.com
 When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug's effects, scientists have found. Now two new studies identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse's sensitivity to cocaine. Read more »

 If you are looking for a particular object -- say a yellow pencil -- on a cluttered desk, how does your brain work to visually locate it? For the first time, neuroscientists have identified how different neural regions communicate to determine what to visually pay attention to and what to ignore. This finding is a major discovery for visual cognition and will guide future research into visual and attention deficit disorders. Read more »

From:
feeds.sciencedaily.com
 Not that long ago in a hot spring in Kamchatka, Russia, two groups of genetically indistinguishable microbes decided to part ways. They began evolving into different species – despite the fact that they still encountered one another in their acidic, boiling habitat and even exchanged some genes from time to time, researchers report. This is the first example of what the researchers call sympatric speciation in a microorganism. Read more »

 Researchers have found new evidence to explain how cholesteryl ester transfer protein (CETP) mediates the transfer of cholesterol from "good" high density lipoproteins (HDLs) to "bad" low density lipoproteins (LDLs). These findings point the way to the design of safer, more effective next generation CETP inhibitors that could help prevent the development of heart disease. Read more »

Cell energy sensor mechanism discovered

From:
feeds.sciencedaily.com
Researchers have discovered more details about how an energy sensing “thermostat” protein determines whether cells will store or use their energy reserves. The researchers have shown that a chemical modification on the thermostat protein changes how it’s controlled. Without the modification, cells use stored energy, and with it, they default to stockpiling resources. When cells don’t properly allocate their energy supply, they can die off or become cancerous.
