Electric fish conduct electric duets in aquatic courtship

...gan in their tails to sense their surroundings and communicate their species, sex and social status with other fish. It is also the first study to successfully sort signals in electric fish based on sex. The research, which is the cover story in the July 1 issue of the Journal of Experimental Biology, is auth...

Turn-ons and turn-offs for neurons

...ons in our brain becomes active. These nerve cells communicate with each other by chemical and electrical impulses to compute incoming sensory information and integrate it via distinct brain regions. With 20,000 - 25,000 genes in our genome, most also expressed in neurons, there is now little doubt that neurons ...

Left-right wiring determined by neural communication in the embryonic worm

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...p forward in the understanding of how chloroplasts communicate with a cell’s nucleus when stresses such as drought, heat, salinity or light become too great on the organism. A research team that includes Shai Koussevitzky, a research associate in the University of Nevada, Reno’s College of Agriculture, Biotech...

Uniform language for describing genes of pathogenic and beneficial microbes

...ut microbe-host interactions will help researchers communicate information, and expand concepts from the studies of microbes and their hosts," said Maryanna Henkart, Director of the National Science Foundation's Division of Molecular and Cellular Biosciences. João Setubal, Deputy Director of the Virginia Bio...

In young mice, gregariousness seems to reside in the genes

...d in to the ultrasonic chattering that mice use to communicate with each other. For the more socially predisposed animal, gregariousness was the order of the day, says Lahvis: "A young mouse will seek social interaction and avoid isolation. The social life of these animals is a rich integration of behavior, v...

Metacognition: Faced with a test, rats can check their knowledge first

...nimals is made difficult by our limited ability to communicate with animals about abstract information or concepts. But in past work, metacognition in primates had been successfully probed by employing an ingenious technique: Animals were familiarized with a test that assessed a certain kind of knowledge that th...

Technology reveals 'lock and key' proteins behind diseases

...ied six proteins that interact with and presumably communicate with the ABC transporter Ycf1p, a yeast version of the human proteins CFTR and MRP. These newly discovered protein interactors represent novel potential pharmaceutical targets. Through a series of biochemical and genetic tests, the researchers discov...

Autism gene identified by researchers at Yale working with a global research consortium

Autism Spectrum Disorders are diagnosed in one in 150 children in the United States, affecting four times as many boys as girls. The diagnosis of autism has ...

Insomnia drug can improve brain function

...out of insomnia; 20 minutes later, she was able to communicate to her family, eat by herself, and move. These effects lasted for up to three hours. After systematically withdrawing all of her medications one by one, it was concluded that the positive effect was due to zolpidem. "This phenomenon was so reproducib...

University of Alberta researchers unravel intricate animal patterns

...is a connection between the signals animals use to communicate with each other and their behaviour," said Raluca Eftimie, a graduate student in the U of A’s Centre for Mathematical Biology. "But until now, the connection between the complex spatial group patterns that we can see in nature and the different ways ...

Biologists call for better choice of model organisms in 'evo-devo'

...ing sources. "We encourage evo-devo workers to communicate with funding agents so that the limited resources available will not be disproportionately channelled to the ‘big six? which, while important, cannot illuminate all evo-devo’s central themes.

Brain works more chaotically than previously thought

...urophysiology this means that nerve cells can only communicate with a small number of other nerve cells, i.e. only with those with which they are connected via synapses. This concept is the basis of the notion that neuronal information in the brain, somewhat like electricity in a computer, only spreads direction...
