Beijing moves to root out GM crops

A ban on genetically modified crops is finally set to become law amid claims that mainland diners are unwittingly being served up transgenic rice.

The issue has sparked heated debate following media reports that GM rice has already made it on to the dinner plate, but the draft law has been met with criticism that it does not go far enough.

How Jingjing can help reveal the mysteries of DNA sequencing

What is DNA sequencing about? Let's take the panda as an example.

Organisms' genomes could contain billions of base pairs - nucleotides on opposite sides of a DNA strand. DNA sequencing uses biochemical methods to determine the order of these nucleotide bases, which have only four types. Their initial letters are A, T, G and C.

Inherited mess-up

A chimera is a creature from Greek mythology. It's made up of parts of several different animals. But when the term applies to humans, it's very real and very, very weird.

Bank to the future

Death is not what it used to be. When you officially log off for good, traces of your identity may still be discovered scattered across the internet. But if you want to leave more than just a shadowy presence and achieve a kind of immortality, you can sign up for a new service run by Swiss DNA Bank.

A leader needed for next green revolution

No winner of the Nobel Peace Prize could claim to have saved as many lives as the late Norman Borlaug. The high-yield, disease-resistant wheat varieties the American pioneered in the 1960s in response to a looming population crisis earned him the title 'father of the green revolution'.

DNA evidence needs to be handled with care

A group of Israeli scientists has recently caused alarm by showing how DNA evidence can be manufactured - showing how it is theoretically possible, using sophisticated techniques in molecular biology and genetic profiling, to fabricate DNA evidence to implicate an innocent person or violate his or her privacy.

Premier Wen comes out in full support of GM crops

The central government will use transgenic crops to boost farmers' incomes and reinvigorate the rural economy, Premier Wen Jiabao told Science magazine.

Mr Wen, a geologist by training, said science and technology were the 'well- springs' of development. In contrast to previous ambiguity, he openly supported the commercial growth of genetically modified crops.

Dinosaur thinking is no match for gene geniuses

When Edinburgh scientists announced the successful cloning of Dolly the sheep more than a decade ago, people around the world were amazed and concerned. They knew, instinctively, that something morally problematic had just happened. Something similar happened again in the world of genetic research last week.

Crop crisis ignites drive for transgenic rice

Last summer brought nothing but scarcity for the rice farmers of Licun village in Fujian province. Half of their regular strains of hybrid rice died despite an abundance of rainfall, sunshine, pesticide, fertilisers and sweat.

Their big fear is that there will be poor harvests again this year.

Question of the week: What do you think about genetic engineering?

Chan Kin-kan, 15, Diocesan Boys' SchoolPeople say that genetic engineering is unnatural and even evil. But this 'evil' technology reduces production costs, meaning the poor can afford more food. Genetically engineered crops have better resistance to pests and diseases. They have a longer shelf life, so are easier to transport.
