Quitting Smoking, Exoplanets and Carnivorous Plants!
Nicotine Replacement not the key for Smokers wanting to Break the Habit.
As many smokers try to fulfil resolutions to quit this month, nicotine replacement therapies have been shown to have no long-term benefits for smokers trying to kick the habit.
Following 787 adult smokers over five years, Gregory Connelly and colleagues from the Harvard School of Public Health found one third of smokers relapsed when trying to quit and saw no difference in this relapse between those using therapies such as nicotine gums and patches to those using other methods, or going cold turkey, in the long term.
Planets for Every star in our Galaxy
Our galaxy has
as many planets as it does stars according to scientists at the University of St Andrews.
Using gravitational microlensing to find planets located further away from their stars, Martin Dominik and colleagues discovered a large population of planets which calculations estimate to equal the number of stars in the Milky Way and further showed that stars without associated planets could be the exception.
Using Fungi to Fight Lead Pollution
Fungi could hold the key to fighting lead pollution according to research published in the journal
A known environmental pollutant, lead is a widely used structural and industrial material worldwide with previous efforts to contain or control levels in contaminated sites proving challenging.
Now Geoffrey Gadd from the University of Dundee has found that fungi can be used to transform lead into pyromorphite - it's most stable mineral form.
Worming a Plant meal
And finally, A carnivorous plant residing in the tropical savannahs of the Brazilian Cerrado region uses sticky underground leaves to trap and digest nematodes.
Ciao Pereira from the state university of Campinas fed nematodes labelled with isotopes of nitrogen to the plant Philcoxia Minensis and found significant levels of nitrogen thereafter in the leaves of the plant, proving the plants digestion and absoroption of the worms.
It's thought the plant uses phosphatase enzymes to directly breakdown the nematodes for nutrition.
The work was published this week in the journal
