Researchers Find Genes That Influence West Nile Virus

...ill provide a road map for other people to ask these types of questions." Another expert pointed out that the researchers have basically started to untangle how the virus uses the host's cellular processes to replicate. "The finding has good potential to provide us with novel targets in humans that can...

Homosexual behavior due to genetics and environmental factors

...ation-based survey of all adult (20-47 years old) twins in Sweden. Studies of identical twins and non-identical, or fraternal, twins are often used to untangle the genetic and environmental factors responsible for a trait. While identical twins share all of their genes and their entire environment, fraternal ...

DNA with a twist: New company to search for cancer drugs and antibiotics

... becomes tangled as a result of various cellular processes, such as replication, which ultimately stops these processes continuing. DNA topoisomerases untangle it. Without them cells die, says Inspiralis co-founder Dr Nicolas Burton. Topoisomerases are already targets for several drugs, including a...

Targeting gut bugs could revolutionize future drugs, say researcher

...nt focus of most drug development programmes, could provide an array of uncharted possibilities for fighting disease. Much research is still needed to untangle the precise role played by each different type of bug. Professor Jeremy Nicholson, one of the authors of the Perspective from the Department of Bio...

MIT probe may help untangle cells' signaling pathways

CAMBRIDGE, Mass.--MIT researchers have designed a new type of probe that can image thousands of interactions between proteins inside a living cell, giving them a tool to untangle the web of signaling pathways that control most of a cell's activities. "We can use this to identify new protein par...

Salk scientists untangle steroid hormone signaling in plants

When given extra shots of the plant steroid brassinolide, plants "pump up" like major league baseball players do on steroids. Tracing brassinolide's signal deep into the cell's nucleus, researchers at the Salk Institute for Biological Studies have unraveled how the growth-boosting hormone accomplis...

Knee injuries may start with strain on the brain, not the muscles

...st research and prevention of ACL injuries focuses below the waist in a controlled lab setting, but the U-M approach looks a bit north and attempts to untangle the brain's role in movements in a random, realistic and complex sports environments. The findings could have big implications for training program...

Free online toolkit provides standard measures for genome and population studies

Cold Spring Harbor Laboratory scientists trace a novel way cells are disrupted in cancer

... treatment. Cancers are enormously complex, and eventually, in most instances, they find ways of disrupting a large fraction of cellular processes. To untangle and reverse the changes, researchers seek to identify sequences of events in which molecules each affect one another in turn, ultimately inducing canc...

Woolly-mammoth gene study changes extinction theory

...olecular analysis of entire collections seems now possible, an effort that the team calls "Museomics."
