Brett Smith for redOrbit.com - Your Universe Online Many a pleasant summer’s evening has been ruined by the onset of swarms of mosquitoes, and studies have shown that the flying pests are drawn to both the carbon dioxide we exhale and the scent of our skin. A new study, published in the journal Cell, has found that mosquitoes actually use the same olfactory mechanism to detect both carbon dioxide and skin odors. "It was a real surprise when we found that the mosquito's CO2 receptor...

Odor And The Brain: What The Nose Knows
2012-11-15 11:36:09

Lawrence LeBlond for redOrbit.com - Your Universe Online Specific patterns in the nasal passageway that determine which olfactory neurons are associated with which particular odors have remained a mystery for scientists. The human nose has millions of these olfactory neurons grouped into hundreds of different neuron types. And each of these neuron types expresses only one odorant receptor in one region of the brain, allowing that specific odor to be sensed. Now, researchers from UC...

In a dramatic breakthrough in the battle against malaria, researchers have identified a low-cost chemical that interferes with a mosquito's ability to detect humans, scientists said on Wednesday. Experts hope the findings could help develop the next generation of mosquito traps and repellents, which could confuse, deter or trap the insects. The chemicals consist of odor molecules that disrupt carbon-dioxide sensors that alert mosquitoes to exhaled human breath, which signals the presence of a...
