Smoking is in the genes


Dutch researcher Jacqueline Vink has discovered that the number of cigarettes smoked per day and the level of nicotine dependence is largely down to a person’s genes. She investigated the smoking behaviour of more than 16,000 twins and their relatives.

Whether or not a young person starts smoking largely depends on his or her environment. Smoking friends and family members increase the chance that someone will take up smoking. Jacqueline Vink discovered that the variation between smokers in the number of cigarettes smoked per day is genetically determined. The same is true for the degree of nicotine dependency.

However, a predisposition for nicotine addiction does not mean that somebody will also become addicted or remain addicted. Smokers who have a genetic disposition can still stop smoking, even though they probably belong to the group who finds it hardest to quit.

Vink also investigated which genes play a role in smoking. She found that chromosomes 6 and 14 contain regions involved with taking up smoking. On chromosome 3 there is a region involved in the number of cigarettes that somebody smokes per day. Chromosome 10 contains a region that plays a role in both the number of cigarettes smoked per day as well as the chance that somebody takes up smoking. Further research is needed to determine exactly which genes are involved.

For her research, the Ph.D. student used data from a large study of more than 16,000 twins (and their relatives) from the Dutch Twin Register. Some of the people questioned also supplied DNA material for the study.

This study is part of the Addiction programme from NWO and ZonMw (Netherlands Organisation for Health Research and Development).

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
