Advances in bioengineering had allowed scientists to understand the complex processes within the poppy plant that convert sugar to morphine,

One was that scientists hadn't figured out all of the steps involved in making morphine from glucose within the poppy plant--in particular

praised the researchers for stopping short of producing heroin and morphine, in their experiments. While noting that the work will need still refinement before it becomes a public health threat,

he marveled at how quickly developments had been unfolding in bioengineering--for morphine synthesis and other applications that would require policymakers to sit down with scientists

#'Home-brewed morphine'made possible Scientists have figured out how to brew morphine using the same kit used to make beer at home.

They have modified genetically yeast to perform the complicated chemistry needed to convert sugar to morphine.

But by borrowing DNA from plants, scientists have been genetically engineering yeasts that can perform each of the steps needed to convert sugar into morphine.

and the scientists say it should now be possible to put all the steps together and"brew"morphine.

"Morphine plays a vital role in pain relief in many hospitals, but it requires a poppy harvest to manufacture.

Brewed morphine could, eventually, be easier to produce. It could also allow scientists to tweak each of the steps to develop new types of painkiller.

and basic skills in fermentation would be able to grow morphine producing yeast using a a home-brew kit for beer-making,
