Assaulting the mosquito's sense of smell
The mosquito may be nature's most effective bioterrorist, accounting for millions of deaths each year. But the end of its eons' long reign of terror may be in sight. Scientists have begun to apply the power of genomics and molecular biology to understand how the mosquito detects the subtle chemical cues that lead it to its targets. (2001-11-26)

Growth factor stimulation leads to increase in new neurons in the brain
Emory University researchers have demonstrated that several regions of the adult rat brain have the capacity to acquire new neurons following the introduction of a growth factor into the brain's lateral ventricle, located in the depths of the cerebral cortex. The study is the first to show the presence of numerous new neurons in certain regions of the brain where they previously have not been found, and suggests that the adult brain may be able to replace neurons lost due to injury or disease.

Eavesdropping on the brain
At a given moment, the brain knows instantly how to classify what information it wants, and discard or store the rest. If we could get our sensors to do it just as well and just as fast, then problems might be solved that today defeat even the fastest computers. (2001-05-09)

Scientists find just how discriminating a worm can be: Unique system of overlapping odor sensors discovered
With only 32 of its 302 nerves dedicated to detecting the odors that drift through its world, the lowly roundworm seems hard pressed to smell food, let alone discriminate friend from foe. But researchers have discovered a unique system of overlapping sensors that enables the creature to tell smells apart. (2001-04-04)

(2000-08-27)

Dogs have a nose for it
American researchers are unlocking the secrets of a dog's amazing sense of smell to develop an artificial nose for sniffing out landmines. The machine mimics the way a dog samples air by 'breathing' air in and out, instead of drawing it straight through. (2000-08-22)

Parents' escape drinking evokes children's negative response to alcohol smell
Researchers at the Monell Chemical Senses Center in Philadelphia report in today's Alcoholism: Clinical and Experimental Research that children between the ages of 3 and 6 years are likely to dislike the smell of beer if their parents report drinking to escape feelings of unhappiness. (2000-08-13)

Gene found responsible for social amnesia
Reporting in the July issue of Nature Genetics, scientists at the Center for Behavioral Neuroscience at the Yerkes Regional Primate Research Center at Emory University have discovered in mouse studies that the oxytocin gene is necessary for forming social memories -- allowing you to recognize an individual you've seen before. (2000-06-18)

Blister beetles use sex and subterfuge to infiltrate bee's nests
Researchers from San Francisco State University report the first case of parasitic insects cooperating to mimic female host species. Forming wriggling masses that resemble and perhaps smell like female bees, newborn blister beetle larvae from the Mojave Desert seduce male bees into pseudocopulation as part of a three-step strategy to take over their nests. (2000-05-02)

Creating a standard spectrum of smell
Some people have a heightened sense of smell and can be overwhelmed by aromas. Some people suffer from smell blindness, a condition appropriately called (2000-03-25)

Bitter taste receptors identified
HHMI researchers and their colleagues have identified a new family of genes that encode bitter taste receptors. The research unveils the molecular logic behind the sense of taste, and may allow scientists to probe how tongue and brain work together to discern a chemical's taste. (2000-03-16)

Don't slight the birdbrain
In the February Neuron, Macklis, a neuroscientist at Boston's Children's Hospital, reports with his collaborators Constance Scharff and Fernando Nottebohm of Rockefeller University and others that they have coaxed high-level neurons in adult zebra finches to be replaced by the bird's endogenous precursor cells. (2000-02-23)

Neurons produced during adulthood react to stimuli
Brain cells that are produced in adult mammals respond to sexual stimuli, according to a team of biologists at the University of Massachusetts. The finding may eventually help in finding treatments for disorders such as stroke, Alzheimer's disease, and Parkinson's disease. (1999-10-24)

Scientists find first molecule that guides nerve cells through the brain
When nerve cells migrate from their birthplace to their permanent home in the brain, how do they find their way? Researchers have discovered the first molecular guide, a known protein called Slit. This protein doesn't attract young cells to where they need to go. It repels them, like a dog herding a flock of sheep. (1999-07-22)
