Tracking the happiness hormone: Electrochemical serotonin microsensors for stable long-term measurement in real time
Dysregulation of serotonin plays a role in many psychiatric disorders, including severe depression and anxiety. In the journal Angewandte Chemie International Edition, a research team has now introduced an implantable, electrochemical microsensor tha.....»»
Researchers identify the neurons that synchronize female preferences with male courtship songs in fruit flies
When it comes to courtship, it is important to ensure that one is interacting with a member of the same species. Animals use multiple sensory systems to confirm that potential mates are indeed suitable, with acoustic communication playing an importan.....»»
Examining the chemicals involved in insect mating
It's almost Valentine's Day, and love is in the air. Or in the waxy coating on your skin, if you are a vinegar fly. That's where flies encounter pheromones that play an important role in regulating sexual attraction......»»
Researchers uncover dynamics behind protein crucial in breast cancer
Watching a puppet show can teach you something about how estrogen works in the body, according to Rice University scientists whose research could open the door to new strategies for regulating the hormone—which could help prevent breast cancer an.....»»
Mating causes "jet lag" in female fruit flies, changing behavior
An innovative technique from Cornell University researchers finds seminal fluid protein transferred from male to female fruit flies during mating changes the expression of genes related to the fly's circadian clock......»»
Prairie voles without oxytocin receptors can bond with mates and young
The vital role of oxytocin—the "love hormone"—for social attachments is being called into question. More than 40 years of pharmacological and behavioral research has pointed to oxytocin receptor signaling as an essential pathway for the developme.....»»

Exercise curbs insulin production in fruit flies
Insulin is an essential hormone for humans and many other living creatures. Its best-known task is to regulate sugar metabolism. How it does this job is well understood. Much less is known about how the activity of insulin-producing cells and consequ.....»»
Fewer moths, more flies: Complex relationships between plants and pollinators have changed dramatically
Their service is invaluable. The army of insects and other animals that pollinates the numerous plants of this earth has an essential function. Without these flower visitors, numerous wild plants could reproduce only poorly—or not at all. Ecosystem.....»»
Unraveling the selective transport of sugar and a hormone that underlies male fertility in plants
Researchers at Nagoya University, Japan, have discovered a mechanism for the selective transportation of sugar and hormones in plants. The results also clarify that sugar transportation is necessary for male fertility in plants, which means pollen pr.....»»
Male fruit flies found to transfer chemical to females to induce sleep, so they won"t mate with other males
A team of researchers from Bariloche Atomic Center and Fundación Instituto Leloir—IIBBA—CONICET, both in Argentina, has found that male fruit flies inject females with a chemical while mating that makes them sleep after sex so that they will not.....»»
Fruit flies use two muscles to control pitch for stable flight
