Smell that memory
People can recall Viking museum experiences better after they've been exposed to Viking smells. This improvement occurred even though the recall interval was about six years and seems to show that smell has a vital role to play in memory. view more (1999-02-01)
Barrow researchers identify new brain receptor, possible target for Alzheimer's treatment
Barrow Neurological Institute researchers have identified a novel receptor in the brain that is extremely sensitive to beta-amyloid peptide (AB) and may play a key role in early stages of Alzheimer's disease. view more (2009-07-17)
Weizmann Institute scientists reveal how some aromas are bound up in our memories
From Proust's Madeleines to the overbearing food critic in the movie Ratatouille who's transported back to his childhood at the aroma of stew, artists have long been aware that some odors can spontaneously evoke strong memories. view more (2009-11-10)
Brown Chemists Explain the Origin of Soil-Scented Geosmin
Brown University chemists have found the origins of an odor - the sweet smell of fresh dirt. In Nature Chemical Biology, the Brown team shows that the protein that makes geosmin - source of the good earth scent - has two similar but distinct halves, each playing a critical role in making this organic compound. view more (2007-09-17)
Stoned sea-squirts
The psychoactive ingredient of the drug cannabis exerts its effects on the human brain by activating proteins known as cannabinoid receptors. Dr. Maurice Elphick of Queen Mary, University of London has uncovered the first evidence that cannabinoid receptors may not be unique to humans and other vertebrates. The genome of the sea- squirt was... view more... (2004-03-31)
Why some adults need security blankets
Many adults will remember a favourite soft toy or blanket which they used to carry around when they were a child - like Linus in the Peanuts cartoon strip. Or they will have seen their own children hanging on to a particular toy.

Before giving flowers or scattering rose petals on Valentine's Day, make sure your significant other has already gotten out of bed. view more (2006-02-03)
NYU Researchers id new class of photoreceptors,pointing to new ways sights-and smells-are regulated
The identification of a new class of photoreceptors in the retina of fruit flies sheds light on the regulation of the pigments of the eye that confer color vision, researchers at New York University's Center for Developmental Genetics report in a new study appearing in the Public Library of Science's journal, PloS Biology. view more (2008-04-22)
Scientists explain how 'death receptors' designed to kill our cells may make them stronger
It turns out that from the perspective of cell biology, Nietzsche may have been right after all: that which does not kill us does make us stronger. view more (2009-06-02)
Sell-by date "arbitrary" on some food packaging
New research on untreated green olives has found that products with a stated shelf-life of 2-3 years can be 'unacceptable' long before their sell-by date. The study, published in the Journal of the Science of Food and Agriculture, looked at the growing trend towards using polyethylene pouches which are vacuum-packed, filled with brine or packed in... view more...

Biologists find biological clock for smell in mice
Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours. view more (2006-12-19)
Research clarifies how brain replenishes memory-making molecules
Memory formation is thought to involve a strengthening of the communication between neurons in the part of the brain known as the hippocampus. view more (2005-12-22)
Deep-sea Ecosystem Engineers
Tube worms living at deep-sea oil seeps in the Gulf of Mexico significantly alter their habitat, similar to beavers altering the flow of a river. Researchers from Pennsylvania State University have just published an important finding in the journal Ecology Letters. A computer model of tube worm aggregations was created for Lamellibrachia luymesi,... view more... (2003-03-12)
Study examines treatment for olfactory loss after viral infection
Treatment with a glucocorticoid medication, either alone or in combination with Ginkgo biloba, appears to significantly improve the sense of smell in individuals with previous olfactory loss due to upper respiratory infections. view more (2009-10-20)
The first virtual reality technology to let you see, hear, smell, taste and touch
The first virtual reality headset that can stimulate all five senses will be unveiled at a major science event in London on March 4th. view more (2009-03-04)
New understanding of basic units of memory
A molecular "recycling plant" permits nerve cells in the brain to carry out two seemingly contradictory functions - changeable enough to record new experiences, yet permanent enough to maintain these memories over time. view more (2007-09-20)
Kids connect alcohol odors with mom's emotions
