Institute of Physics An implantable device that reduces blood pressure by sending electrical signals to the brain has been created by a group of researchers in Germany. The device has successfully reduced the blood pressure in rats by 40 per cent without any major side effects, and could offer hope for a significant proportion of patients worldwide who do not respond to existing medical treatment for the condition. The first results have been published today, 9 May, in IOP...

Max Planck Institute for Chemical Ecology Odorant receptors of recent insects evolved long after insects migrated from water to land. An insect’s sense of smell is vital to its survival. Only if it can trace even tiny amounts of odor molecules is it is able to find food sources, communicate with conspecifics, or avoid enemies. According to scientists at the Max Planck Institute for Chemical Ecology, many proteins involved in the highly sensitive odor perception of insects emerged...

Human Nose Can Distinguish More Than 1 Trillion Scents

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...

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...

Photoreactive compounds developed by LMU scientists directly modulate nerve-cell function, and open new routes to the treatment of neurological diseases, including chronic pain and certain types of visual impairment. All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of...

How Do Fruit Flies Detect Sweet Foods?

University of California - Riverside UC Riverside research opens door for investigations into taste receptors of mosquitoes and other deadly insects Insects represent remarkable diversity and have adapted to all sorts of ecological nooks and crannies. For example, they have taste receptors — novel proteins — with which they taste chemicals and make important choices about not only foods but also mates and where to deposit their eggs. These receptors are widely seen as being at the...

Odor Receptors Found In Lungs
2014-01-03 10:22:27

Brett Smith for redOrbit.com - Your Universe Online New research published in the American Journal of Respiratory Cell and Molecular Biology has revealed that odor receptors aren’t just found in the nose – they also line the lungs as well. However, instead of being used to detect the aroma of blueberry cobbler or a succulent roasting chicken, the odor receptors in the lungs trigger a response designed to protect the airways. “We forget,” said study author Yehuda Ben-Shahar,...

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...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
