Tropical butterflies demonstrate novel mechanism for protecting themselves from cyanide in passion vine

July 12, 2000

A colorful butterfly species found in tropical rainforests in Central and South America has evolved a remarkable method for overcoming cyanide producing compounds in passion vines, according to biologists at The University of Texas at Austin. The scientists believe their discovery has potential implications for the development of safer tropical food crops -- which today are associated with chronic health problems.

Auditory brains different in homosexuals and heterosexuals

July 12, 2000

"A large number of physiological and behavioral measures reveal differences between heterosexuals and homosexuals," said McFadden. "The problem for science is to identify the mechanisms--presumably they are hormonal mechanisms--that produce these differences. Our findings suggest that the auditory system may be a valuable, if unlikely, tool for studying those causal mechanisms. Apparently whatever developmental mechanisms are acting to produce homosexuality are also affecting components of the auditory system."
