When you're on a diet, deciding to skip your favorite calorie-laden foods and eat something healthier takes a whole lot of self-control--an ability that seems to come easier to some of us than others. Now, scientists from the California Institute of Technology (Caltech) have uncovered differences in the brains of people who are able to exercise self-control versus those who find it almost impossible.

The key? While everyone uses the same single area of the brain to make these sorts of value-laden decisions, a second brain region modulates the activity of the first region in people with good self-control, allowing them to weigh more abstract factors--healthiness, for example--in addition to basic desires such as taste to make a better overall choice.

"The method we have developed means we can simultaneously detect various kinds of antibiotic residues (macrolides, tetracyclines, quinolones and sulfonamides) in honey", Antonia Garrido, lead author of the study and the researcher in charge of the UAL's Contaminants Analytical Chemistry Research Group, told Servicio de Información y Noticias Científicas (SINC).

In order to develop this method, the results of which have been published recently in the Journal of Agricultural and Food Chemistry, the researchers employed ultra performance liquid chromatography, a technique that makes it possible to separate the components of a sample, together with mass spectrometry, which permits the simultaneous identification of up to 17 antibiotics.

With the new movie ‘Star Trek’ opening in theaters across the nation, one thing movie goers will undoubtedly see is the Starship Enterprise racing across the galaxy at the speed of light but two Baylor University physicists believe they have an idea that can turn traveling at the speed of light from science fiction to science, and that their idea does not break any laws of physics.
