Human Nose Can Distinguish More Than 1 Trillion Scents
2014-03-21 04:48:03

redOrbit Staff & Wire Reports - Your Universe Online For decades, experts have claimed that people were capable of detecting 10,000 different odors, but new research appearing in the March 21 edition of Science suggests that the actual number of scents detectable by the human nose is considerably higher. In fact, according to an experiment led by Andreas Keller of the Rockefeller University Laboratory of Neurogenetics and Behavior, human noses and brains are sensitive enough to...

Heart Attack Patients May Soon Have Side Effect-Free Drug Option
2014-03-12 06:36:52

April Flowers for redOrbit.com - Your Universe Online A new drug designed to stop a heart attack in its tracks, while reducing the damage caused, all without side effects, is one step closer to development thanks to a group of Melbourne scientists from Monash University. New hope for thousands of people who experience heart attacks and heart failure is provided by the study, published in a recent issue of Proceedings of the National Academy of Sciences. A team of scientists, led by...

Detailed Picture Of Protein Linked To Learning, Pain And Brain Disorders Created By Scientists
2014-03-07 11:26:29

Scripps Research Institute Researchers at The Scripps Research Institute (TSRI) and Vanderbilt University have created the most detailed 3-D picture yet of a membrane protein that is linked to learning, memory, anxiety, pain and brain disorders such as schizophrenia, Parkinson's, Alzheimer's and autism. "This receptor family is an exciting new target for future medicines for treatment of brain disorders," said P. Jeffrey Conn, PhD, Lee E. Limbird Professor of Pharmacology and director...

Brett Smith for redOrbit.com - Your Universe Online While scientists know that a superfamily of genes inside olfactory receptors is responsible for our sense of smell – we still don’t know the mechanism behind the interpretation of odor molecules into a particular smell. A new study published in the journal Molecular Biology and Evolution has found a distinct gene pattern in the olfactory receptors of fruit-eating bats – potentially shedding some light on the mechanism behind our...

Xray Maps GPCR
2013-12-20 12:57:28

redOrbit Staff & Wire Reports - Your Universe Online Researchers have used one of the brightest X-ray sources in the world to map the three-dimensional structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than has been previously possible. The new technique, described Friday in the journal Science, is a major leap forward in exploring GPCRs, a vast, hard-to-study family of proteins that plays a key role in human health...

STRASBOURG AND MONTRÉAL, Dec. 18, 2013 /PRNewswire/ - Domain Therapeutics, a France-based biopharmaceutical company that specializes in the research and development of new drug candidates that target G-protein coupled receptors (GPCRs), is pleased to announce the signing of a licensing and partnership agreement on GPCR biosensor technology with Université de Montréal (UdeM) and its commercialization unit, with the Institute for Research in Immunology and Cancer -...

Genetics Play A Large Part In Olfaction
2013-12-14 05:33:05

April Flowers for redOrbit.com - Your Universe Online People react differently to the same smells. Something that smells wonderful to you could be offensive to your friend, but why this is so has been a mystery. The answer could lie in your genetic makeup, says a research team from Duke University. Their findings, published in the early online edition of Nature Neuroscience, reveal that a difference at the smallest level of DNA — one amino acid on one gene — determines whether or not...

We each live in a unique odor world According to Gertrude Stein, "A rose is a rose is a rose," but new research indicates that might not be the case when it comes to the rose's scent. Researchers from the Monell Center and collaborating institutions have found that as much as 30 percent of the large array of human olfactory receptor differs between any two individuals. This substantial variation is in turn reflected by variability in how each person perceives odors. Humans have about...

Smell Processes In Our Brain Better Understood Through Locust Study
2013-11-26 09:53:56

April Flowers for redOrbit.com - Your Universe Online Environmental stimuli often trigger our sense of smell before we exhibit any other response. Smells trigger neurons in our brains that alert us to take action, but there are often more than one odor in our environments at any given time. Barani Raman, PhD, of the School of Engineering & Applied Science at Washington University in St. Louis, wanted to answer the question of how our brain processes multiple odors received...

Similar to passengers on an urban transit system, every protein made in the cell has a specific destination and function. Channels in cell membranes help direct these proteins to their appropriate target. Researchers at Boston University School of Medicine (BUSM) and their colleagues have now captured images of these channels as they open to allow proteins to pass through a membrane, while the proteins are being made. These findings are published as a Letter in Nature (Park, E. et al. 2013)....
