Using a new microscopic "fishing" technique, scientists from the Montreal Clinical Research Institute (IRCM), Universit茅 de Montr茅al and 91丝瓜视频 have successfully snagged thousands of proteins that play a key role in the formation of the cell skeletons or cytoskeletons. Cell skeletons, whose primary function is to give the cells their shapes, are also involved in things like muscle contraction. They are made up of an interlocking network of protein filaments that connect the cell nucleus to the cell membrane.

91丝瓜视频 marine ecologist is bringing cutting-edge DNA analysis to the formidable task of tracking ocean species along Canada鈥檚 Pacific coast.

New work from the聽Gregor Fussmann聽Lab in Proceedings of the Royal Society B: One of the basic tenets of ecological theory is that connectivity among small populations over a larger landscape (metapopulations) promote species persistence. In this experiment we investigate to what degree and under what conditions this theory holds true when parasites are added to the equation, using lab-based populations of guppies and their ectoparasite聽Gyrodactylus turnbulli.

The research has implications for understanding human developmental disorders such as autism

Adult songbirds modify their vocalizations when singing to juveniles in the same way that humans alter their speech when talking to babies. The resulting brain activity in young birds could shed light on speech learning and certain developmental disorders in humans, according to a study by 91丝瓜视频 researchers.

Life in the city changes cognition, behavior and physiology of birds to their advantage

Birds living in urban environments are smarter than birds from rural environments.

But, why do city birds have the edge over their country friends? They adapted to their urban environments enabling them to exploit new resources more favorably than their rural counterparts, say a team of all-91丝瓜视频 researchers.
