Smell-wars Between Butterflies And Ants (1/7/2008)

Smell-wars Between Butterflies And AntsAmong humans, making yourself smell more alluring than you really are is a fairly harmless, socially accepted habit that maintains a complete perfume industry. However, it is a matter of life and death for caterpillars of large blue butterflies that dupe ant workers into believing them to be one of the ant's own larvae. ...> Full Article



Scientists Reveal Role of Gene in Sensitivity to Thermal Pain (12/30/2007)

Scientists Reveal Role of Gene in Sensitivity to Thermal PainThe skin is the largest human sensory organ. What is not fully understood is how the skin responds to stimuli, especially to pain. Research by Nevena Milenkovic, Christina Frahm, Professor Gary Lewin and Dr. Alistair Garratt of the Max Delbrück Center for Molecular Medicine (MDC) in Berlin-Buch, Germany, has now demonstrated that Stem Cell Factor (SCF) and its receptor, c-Kit, play a central role in tuning the responsiveness of sensory neurons to heat stimuli. "As yet, c-Kit is the first example of a single gene being required for normal noxious heat sensitivity of C-fibers," according to the neurobiologists. Their paper has just been published online in Neuron *. ...> Full Article



How One Pest Adapted To Life In The Dark (12/24/2007)

How One Pest Adapted To Life In The DarkA type of beetle that lives its entire life burrowing through stored grain has been found to lack full colour vision, and what's more the vision it does have breaks the rules. Most other insects have trichromatic vision -- they are sensitive to ultraviolet, blue and long wavelength light. Scientists now reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths. ...> Full Article

Gene determines whether male body odor smells pleasant (9/18/2007)

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. While many people ascribe a foul odor to androstenone, usually that of stale urine or strong sweat, others find the scent sweet and pleasant. Still others cannot smell it at all. ...> Full Article


Whales evolved biosonar to chase squid into the deep (9/7/2007)

Whales evolved biosonar to chase squid into the deepBehind the sailor's lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths? ...> Full Article

Sour Taste Make You Pucker? It May Be In Your Genes (7/15/2007)

Scientists at the Monell Chemical Senses Center report that genes play a large role in determining individual differences in sour taste perception. The findings may help researchers identify the still-elusive taste receptor that detects sourness in foods and beverages, just as recent gene studies helped uncover receptors for sweet and bitter taste. ...> Full Article
