Organic: Is it the future of farming? p792
In its pure form, maybe not. But elements of the organic philosophy are starting to be deployed in mainstream agriculture. Nature's reporters analyse this trend, assess the extent of organic farming worldwide, and frame the questions on which its wider adoption will depend.

Organic FAQs p796
In the developed world, sales of organic produce are growing rapidly. But how far can this trend extend? That depends on how strictly you define organic farming ... and the answers to three other pivotal questions.

Plant science: Tall storeys p807
The tallest living organisms are trees, but how tall could they be and what stops them growing any taller? Measurements at the tops of the world's tallest trees now provide quantitative answers to these questions.

Applied physics: Speed limit ahead p808
Are there any limits to what science and technology can achieve? When it comes to recording data in magnetic media, the answer is yes: there is a natural limit to the speed at which data can be encoded.

Genomic imprinting: Mice without a father p809
In mammals, genomes from both parents are generally needed to make viable offspring. But changing the expression of 'imprinted' genes can render the father's contribution dispensable.

Cancer: Enzymes play molecular tag p813
The B-RAF protein is often mutated in human cancers, contributing to their development. Although most known mutations stimulate its catalytic activity, others, surprisingly, impair it — yet still cause cancer.
