Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...ficance of their study, saying: “Understanding the genetics behind pathogen/immune system interactions in disease vector mosquitoes may help us understand why, for example, some types of mosquitoes can transmit a particular human pathogen while others cannot. If those that cannot have evolved an effective imm...

Understanding why C. difficile causes disease -- it's hungry

Researchers studying the genetics behind why C. difficile causes disease have come to a simple conclusion -- the bacteria do it because they are starving. That just might help them find a new treatment for what can sometimes be a very difficult disease to treat. "The genes responsi...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...the nerve endings," said Kyrkanides, whose work on genetics in dentistry led to broader applications. The common ground between arthritis and dentistry: a common site of arthritic pain is the jaw joint.

Scientists seek useful traits in wild cottons

...limiting fiber quality and yield potential, narrow genetics makes them more susceptible to insects and disease." Gannaway and other scientists believe future progress in cotton breeding can only be achieved if sufficient genetic variability remains in global breeding stocks. The mission of t...

...d animals differ". The next step will be to use genetics to localize and understand the brain circuits responsible for the spontaneous behavior. This step could lead directly to the development of robots with the capacity for spontaneous nonrandom behavior and may help combating disorders leading to compro...

NIDA study identifies genes that might help some people abstain from smoking

... Volkow. “It marks a movement from identifying the genetics of addiction vulnerability to identifying the genetic basis of successful abstinence. This knowledge could impact the success rate of cessation programs by helping health care providers choose the most appropriate treatment based on individual differ...

Stanford-led study closes in on genes that may predispose some people to severe depression

...is is one of the first big linkage studies on the genetics of depression." Researchers learned that depression is influenced by genetics by studying patterns of depression in twins and families. No single gene is thought responsible fo...

Researchers find gene mutation that causes infertility in male mice

... caused the infertility. While most studies on the genetics of fertility stem from analyses of mice that have had a custom gene "knockout," this is the first to reveal a dominant mutation that leads specifically to infertility in a mammal. The researchers believe this kind of dominant effect is closer to how ...
