Lycopene slows human prostate tumour growth in mice and combined with vitamin E is even better
...ts and natural compounds follow a bell-shaped dose response
curve, which means that very low or high doses may not work and that there is an optimal dose between the two extremes." The study showed that the lycopene and vitamin E were effectively taken up in the mice prostates in the same form as they are in ...

Plants will not save us from greenhouse gases
...ll University biologist Graham Bell, looked at the response
of algae to high carbon dioxide concentrations. Their findings showed that the plants could not adapt to high carbon dioxide conditions. This disproves the previous assumption that plants can take up extra carbon dioxide in the environment. According...
