When a lonely and thirsty male zebra finch encountered a female, his thirst waned and he instead focused his attention on her, a shift reflected in the dopamine system.
“This one gene controls a switch between two alternative cell fates," said Professor Leslie Babonis.

An orb-weaver spider perched in the hub of its wheel-shaped web. The “claw” at the tip of each leg is “hooked” gently onto strategically placed strands of web silk and positioned to “listen” to the miniscule vibrations induced by sound waves that pass through the web.
A study of orb weaver spiders finds their massive webs act as auditory arrays that capture sounds, possibly giving spiders advanced warning of incoming prey or predators.

Fruit fly sperm with heads labelled with a red or a green fluorescent protein, swimming inside a female fruit fly’s reproductive tract.
Long considered exclusively male, a new study revealed that by four days after a sperm enters a female fruit fly, close to 20% of its proteins are female-derived.

Little is known about how higher cortical areas in the brain develop after the primary areas are in place. A new study by Cornell and Yale researchers, including professor emerita of psychology Barbara Finlay, uses computer modeling to show that the development and evolution of secondary visual cortical areas can be explained by the same process.
<p> Scientists have known that females of many species eat more to meet the demands of reproduction, and that females undergo widespread physiological and behavioral changes after mating. The mechanisms of these changes, however, are not well understood.</p>
