Results may help improve drugs for neurological disorders Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors (GPCRs). "The knowledge of how the peptide binds to its receptor should help scientists design...

A new study of the sense of smell lends support to a controversial theory of olfaction: Our noses can distinguish both the shape and the vibrational characteristics of odorant molecules. The study, in the journal Physical Chemistry Chemical Physics, demonstrates the feasibility of the theory — first proposed decades ago — that the vibration of an odorant molecule´s chemical bonds — the wagging, stretching and rocking of the links between atoms — contributes to...

Connie K. Ho for redOrbit.com — Your Universe Online A new study by German researchers found that a light-sensitive element that was mixed with the anesthetic propofol was able to be managed by light and the mixture could possibly be used to treat particular eye disorders. To begin, the scientists believe that inhibitory neurotransmitters can limit the activity of neurons and this reduction effect acts as the foundation for different anesthetics. In particular, propofol can work...

Michael Harper for redOrbit.com - Your Universe Online Cold feet are often equated to cowardice or second-thoughts when it comes to making a life-changing decision, such as going through with a marriage. Cold feet can also be more than just a joke people tell to be folksy. In fact, many people complain about their cold feet or the cold feet of a partner. Now, some physiologists have set their brains about figuring out why some people constantly have cold feet, saying a biological mechanism...

New research in the FASEB Journals demonstrates that blocking the delta opioid receptor in mice created resistance to weight gain and stimulated gene expression promoting non-shivering thermogenesis Imagine eating all of the sugar and fat that you want without gaining a pound. Thanks to new research published in The FASEB Journal (http://www.fasebj.org), the day may come when this is not too far from reality. That's because researchers from the United States and Europe have found that...
