Brain behind the Brawn: Vital Molecule in the Brain Controls Appetite

...em nearly 300 million are obese. Scientists have narrowed their sights on a new molecule that works on the source of the problem – appetite, the main reason for over weight and obesity. This molecule in the brain is capable of making a person feel full, and satisfied, which is what the world needs to set t...

Stroke Linked to High Pollution Levels

Discerning Sour Taste

...es on the tongue,” explained Huang. “Therefore, we narrowed the search down to genes for proteins with a structure that would allow them to be in a cell membrane. Second, we ruled out candidates that were found in many different tissues and focused on those mainly in the taste cells. Third, we looked for a ca...

Sour Taste Sensors Identified

...in to be located in cell membranes. "That screen narrowed the list significantly, from 30,000 to about 10,000," Huang said. She then used what Zuker calls "a stroke of ingenuity" to reduce the list further. Proteins that could detect sour compounds are likely to be found only in small numbers of tissues, in...
