Researchers firmly believe that alcoholism is a complex behavior that draws from both environmental and genetic factors. A recent examination of families selected for their smoking behavior has identified the same region of chromosome four that was identified by earlier studies as being linked to the initiation of alcohol consumption. Results are published in the December issue of Alcoholism: Clinical & Experimental Research.
"It is commonly observed that people that drink also smoke and vice versa," explained Kirk C. Wilhelmsen, associate professor in the departments of genetics and neurology at the University of North Carolina as well as corresponding author for the study. "This suggested to us that families selected for smoking behavior would also have an increased incidence of drinking behavior."
"Twin studies of alcohol consumption have a long history and were the first to suggest the importance of genetic factors in alcohol use and alcoholism," added Gary E. Swan, director of the Center for Health Sciences at SRI International and also an author of the study. "The identification of linkages between specific genomic regions of interest and alcohol use and abuse is an area of science that has been active for about seven years. A consistent finding from these studies is the linkage between a region of chromosome four containing several genes that produce enzymes involved in the metabolism of alcohol and families with a high frequency of alcohol abuse."

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.
Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
