Nature magazine’s flip-flop today (April 2002) over the testing protocols involved in determining GM maize contamination in Mexico - the Centre of Genetic Diversity for the vital food crop - is just the latest in a string of absurdities as the scientific community struggles over what to do as genetically-modified germplasm invades the genetic homelands of the world’s food supply.

MIT says an army of NanoWalkers (microbots) will be performing sub-atomic operations within three months. The development signals a new era in technology as industry prepares to move "down" from genomes to atoms.

Thumbelina with an attitude: Hundreds of three-legged robots the size of a thumb, complete with onboard computers, powerful microscopes, and biosensors will be ready to manufacture nano-scale materials by mid-2002, according to researchers at the Massachusetts Institute of Technology (MIT) Bioinstrumentation Laboratory. A 'nano' is a measurement of one-billionth of a meter. Only 32 millimeters in diameter, the microbots are designed to manipulate atoms. Responding to infrared signals allowing each microbot to act independently or collectively on myriad tasks, the little machines (dubbed "NanoWalkers") are capable of executing 48 million instructions and making 4,000 nano-maneuvers per second. MIT expects to have at least 300 microbots hard at work in an enclosed card-table sized chromium chamber by June. The chromium surface provides an energy source for the robots which will receive their marching orders from a master computer in the box's ceiling.

Si no tiene nada bonito que decir, ¿mejor quedarse callado?

El comité de políticas del CGIAR, la red de científicos agrícolas más grande del mundo, reunido la semana pasada, evadió todas las preguntas difíciles relacionadas con el maíz transgénico en México, centro de diversidad genética de ese cultivo, pese a que el año pasado(2001) y reiteradamente el mes pasado (01/2002), la Secretaría de Medio Ambiente de México confirmó que las variedades nativas de maíz en por lo menos dos estados están contaminadas con ADN de maíz genéticamente modificado.

Unnatural Rejection? The academic squabble over Nature magazine's peer-reviewed article is anything but academic:

More than 144 farmer and other Civil Society Organizations from 40 countries have signed a Joint Statement being released today on the Mexican GM Maize Scandal. The Statement comes on the eve of an international science policy meeting in Los Banos, Philippines where a global response to the scandal will be discussed. The 144 organizations are demanding that the UN Food and Agriculture Organization (FAO) and the Consultative Group on International Agricultural Research (CGIAR) work together with the Convention on Biological Diversity to halt the contamination of the Mesoamerican Centre of Genetic Diversity for maize - one of the world's most important food crops. News that genetically modified (GM) maize was turning up in farmers' varieties first appeared in Nature Biotechnology magazine last September and was confirmed in November by a peer-reviewed article in Nature. According to the 170 signatories to today's Joint Statement, the academic and industry attacks on the findings of the Mexican Government and U.S. university researchers has been orchestrated to keep the scandal from embarrassing the biotech industry as it tries to lift the European, Brazilian, and Mexican moratoria (de facto or otherwise) on genetically modified seeds or foods. If the Philippine meeting of the Genetic Resources Policy Committee of the CGIAR does not act decisively and immediately to protect farmers in Mesoamerica, civil society will take the issue directly to the April meeting of the Biodiversity Convention in the Hague, and the World Food Summit in Rome in June. The text of the Joint Statement follows.
