Scientists discover how to send insects off the scent of crops
Biotechnology and Biological Sciences Research Council (BBSRC)-funded research, published this week in Chemical Communication, describes how scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food... view more... (2009-09-24)
Food peptides activate bitter taste receptors
Researchers from the Monell Center and Tokyo University of Agriculture have used a novel molecular method to identify chemical compounds from common foods that activate human bitter taste receptors. view more (2008-01-23)
Sound investment: A new mathematical method provides a better way to analyze noise
Humans have 200 million light receptors in their eyes, 10 to 20 million receptors devoted to smell, but only 8,000 dedicated to sound. view more (2006-07-27)
Penn study on olfactory nerve cells shows why we smell better when we sniff
Unlike most of our sensory systems that detect only one type of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell, according to University of Pennsylvania School of Medicine researchers in the March issue of Nature Neuroscience. view more (2007-03-14)
Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn. view more (2008-04-14)
Remembrance of smells past: how the brain stores those meaningful memories
Smells trigger memories but can memories trigger smell, and what does this imply for the way memories are stored? A UCL study of the smell gateway in the brain has found that the memory of an event is scattered across sensory parts of the brain, suggesting that advertising aimed at triggering memories of golden beaches and soft sand could well... view more...

Rice psychologist explores perception of fear in human sweat
When threatened, many animals release chemicals as a warning signal to members of their own species, who in turn react to the signals and take action. Research by Rice University psychologist Denise Chen suggests a similar phenomenon occurs in humans. view more (2009-03-09)
Nitric oxide plays a vital role in the formation of long-term memory in snails
Snails can teach us a great deal about how we form memories, according to a group of neuroscientists at the University of Sussex. Research by Dr Ildik'³ Kemenes, Professor Paul Benjamin, Professor Michael O'Shea and colleagues shows that nitric oxide plays a vital role in the formation of long-term memory in snails. This is of crucial importance... view more... (2002-02-18)
When smell cells fail they call in stem cell reserves
Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. view more (2007-04-30)
U of Minnesota researcher discovers the starting point of sun-induced skin cancer
According to a new study from the University of Minnesota, the earliest event in the development of sun-induced skin cancer may have been identified. view more (2008-05-15)
Oestrogen may be associated with virus (HPV) infection implicated in cervical cancer
The female hormone oestrogen may have a role in HPV viral infection, strains of which are implicated in cervical cancer, shows research in Sexually Transmitted Infections. view more (2002-06-17)
Personalized diets may offer relief to advanced cancer patients
It is well known that cancer patients undergoing chemotherapy and radiation therapy often experience nausea and loss of appetite. But until now, few researchers have looked into why this happens and what can be done to ensure that cancer patients maintain a healthy diet during treatment. view more (2007-03-12)
The brain is more adept at using the nose than previously realized
Brains are able to adjust automatically to the demands of distinguishing between small differences in smell, new research at the University of Chicago shows. view more (2007-04-30)
Gene determines whether male body odor smells pleasant
To many, urine smells like urine and vanilla smells like vanilla. But androstenone, a derivative of testosterone that is a potent ingredient in male body odor, can smell like either - depending on your genes. view more (2007-09-17)
A fading sense of smell may signal onset of Parkinson's disease
Many individuals with Parkinson's disease are able to recall losing their sense of smell well before the onset of more commonly recognized symptoms such as tremors, impaired dexterity, speech problems, memory loss and decreased cognitive ability. view more (2008-12-12)
Proteins that stop a major signaling pathway can also generate new proteins
Duke University Medical Center researchers have recently discovered that a crucial communications pathway in cells not only stops cells from making proteins, it also makes them go. view more (2008-04-25)
UCLA researchers discover how drug binds to neurons to stop drunken symptoms of alcohol
UCLA researchers discovered how an experimental drug, called Ro15-4513, binds to specific receptors on brain neurons, which helps explain how this drug stops the drunken behavioral symptoms of alcohol such as impaired motor coordination, memory loss and drowsiness. view more (2006-05-09)
Heat halts pain inside the body
The old wives' tale that heat relieves abdominal pain, such as colic or menstrual pain, has been scientifically proven by a UCL (University College London) scientist. view more (2006-07-06)
A case of false positive octreoscan in Crohn's disease
Neuroendocrine tumors, such as carcinoid tumors, overexpress somatostatin receptors in their membranes. Octreotide is an analogue whose molecule is a shortened version of somatostatin's with a high affinity for these receptors. view more (2008-09-22)
New study by Rice University psychologist finds women's brains recognize, encode smell of male sexual sweat
A new Rice University study published in the Journal of Neuroscience found that socioemotional meanings, including sexual ones, are conveyed in human sweat. view more (2009-01-08)
