This is your brain on fatty acids
Saturated fats have a deservedly bad reputation, but Johns Hopkins scientists have discovered that a sticky lipid occurring naturally at high levels in the brain may help us memorize grandma's recipe for cinnamon buns, as well as recall how, decades ago, she served them up steaming from the oven. view more (2009-11-02)
Scientists find that the human nose is more complicated than a jumbo jet
Winter colds can give you a blocked up nose that stops you smelling chimney smoke, roasting chestnuts, warming winter puddings and the other seasonal scents. Now researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have not only discovered how air moves through the nose bringing you those smells but their work... view more...

Olfactory nerve cells expressing same receptor display a varied set of reactions
n a mouse model, University of Pennsylvania School of Medicine researchers discovered that olfactory sensory neurons expressing the same receptor responded to a specific odor with an array of speeds and sensitivities. view more (2006-02-03)
Researchers create first model for retina receptors
A team of scientists at the University of Oklahoma Health Sciences Center has created the first genetic research model for a microscopic part of the eye that when missing causes blindness. The research appears in a recent issue of the Journal of Biological Chemistry. view more (2008-10-01)
Unique estrogen receptor linked to metastatic breast cancer
Breast cancer awareness month may have passed, but researchers remain focused on the disease with a new study showing that a unique estrogen receptor found in breast cancer tumors is a predictor of tumor size and metastases. view more (2006-11-01)
Cancer vaccine one step closer
Andreea Ioan-Facsinay from Leiden University Medical Center has attached proteins from tumour cells to antibodies. With these she treated immune cells from a mouse. These treated cells were used to make a vaccine, which was shown to be effective in animal experiments. If the follow-up research is successful, vaccines against cancer will become... view more...

Study reveals biochemical signature of cocaine craving in humans
Using sophisticated brain-imaging techniques at the U.S. Department of Energy's Brookhaven National Laboratory, scientists from the National Institute on Drug Abuse (NIDA), Brookhaven Lab, and the University of Pennsylvania have uncovered the brain chemistry that underlies such "cue-induced" craving in cocaine addicts. view more (2006-06-14)
Depression diversity: Brain studies reveal big differences among individuals
Depressed people may have far fewer of the receptors for some of the brain's "feel good" stress-response chemicals than non-depressed people, new University of Michigan Depression Center research shows. view more (2008-05-08)
Our brains make their own marijuana: We're all pot heads deep inside
U.S. and Brazilian scientists have just proven that one of Bob Dylan's most famous lines--"everybody must get stoned"-- is correct. view more (2009-04-21)
New cannabis-like drugs could block pain without affecting brain, says study
A new type of drug could alleviate pain in a similar way to cannabis without affecting the brain, according to a new study published in the journal Pain on Monday 15 September. view more (2008-09-12)
Subliminal smells bias perception about a person's likeability
Anyone who has bonded with a puppy madly sniffing with affection gets an idea of how scents, most not apparent to humans, are critical to a dog's appreciation of her two-legged friends. Now new research from Northwestern University suggests that humans also pick up infinitesimal scents that affect whether or not we like somebody. view more (2007-12-07)
Scientists glimpse a rare human antibody which protects against AIDS
Scientists have obtained their first detailed glimpse of a rare antibody, called b12, which is capable of inactivating many different strains of HIV, the virus which causes AIDS. A crystal structure of b12 has been determined by scientists working at The Scripps Research Institute, California, and the Glycobiology Institute at Oxford University,... view more... (2001-08-08)
Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain. view more (2008-09-29)
DMSO raises a stink at sewage treatment plants
Researchers believe they've found the source of a stinking problem that has plagued areas surrounding sewage treatment plants for decades. view more (2005-12-21)
Increased sensitivity to nerve signals keeps diabetes at bay
Nerve signals relayed directly to the pancreas after eating a meal play a critical role in normal blood sugar control. view more (2006-06-07)
Why prostate cancer patients fail hormone deprivation therapy
The hormone deprivation therapy that prostate cancer patients often take gives them only a temporary fix, with tumors usually regaining their hold within a couple of years. view more (2009-01-05)
Scientists identify protein that may promote migraines
A University of Iowa study may provide an explanation for why some people get migraine headaches while others do not. The researchers found that too much of a small protein called RAMP1 appears to "turn up the volume" of a nerve cell receptor's response to a neuropeptide thought to cause migraines. view more (2007-03-09)
New understanding about mechanism for cell death after stroke leads to possible therapy
Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. view more (2009-11-23)
Like sweets? You're more like a fruit fly than you think...
According to researchers at the Monell Center, fruit flies are more like humans in their responses to many sweet tastes than are almost any other species. view more (2008-03-18)
Carvedilol shown to have unique characteristics among beta blockers
In a new study, researchers report that a class of heart medications called beta-blockers can have a helpful, or harmful, effect on the heart, depending on their molecular activity. view more (2009-11-23)
