Study finds poker players using drugs to enhance performance

A Nova Southeastern University study recently presented at a national conference found that 80 percent of poker players around the world reported using drugs and other substances to enhance their performance in poker.

Poker players are using drugs such as marijuana, cocaine, amphetamines, Valium, and other prescription medications, as well as substances including caffeine, energy drinks and guarana to get an edge over their opponents.

"The use these substances could allow poker players to stay awake longer, as well as focus and concentrate better, which would be a competitive advantage," said Kevin Clauson, Pharm.D., an associate professor at NSU's College of Pharmacy, who was the principle investigator in the study. "Stamina is important for any poker player because tournament poker and cash games can go on for many hours."

Using these substances can be harmful for poker players, Clauson said. Depending on the type of substance, he pointed out; there will likely be short-term and long-term side effects.

The NSU researchers initially interviewed players in Las Vegas during the World Series of Poker and then surveyed players online from across the globe, including North America, Europe, and Asia, with the majority of respondents coming from the US and Canada.

Respondents included professional poker players, semi-pro, amateur, and recreational players. Regardless of one's status, an overwhelming majority of poker involves some amount of money, Clauson said. The players surveyed played poker --- largely no-limit Texas hold' em ---- both in person and on the Internet. Most were males in their mid-20s.

About 73 percent of the respondents said they used drugs and other substances to focus and concentrate better. The rest used these products to calm their nerves, stay awake, and improve memory.

The results suggest that the use of substances to improve poker performance is widespread, especially at higher stakes, Clauson said. "Most people we surveyed are using some kind of a boost in order to play one of the most popular games in the world," he said.

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: 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...
