Genetically modified (GM) plants that use Bt (Bacillus thuringiensis), a common soil bacterium, to kill pests won't harm the pests' natural enemies, according to new research by Cornell entomologists. That is welcome news for ecologists and farmers in the debate over GM plants. Much of the debate surrounding the use of GM crops focuses on their effect on organisms that aren't pests.

Even as corn prices rise with the demand for biofuels, a simmering dispute percolates in Mexico where genetically modified imports from the U.S. are both welcomed and damned. In a debate that pits sovereignty against science, grassroots networks of peasant groups and their allies in academia are challenging the top-down strategies of corporate farming and biotechnology for feeding the world.

Government is making biosafety a priority not only in terms of genetically-modified organisms in food but also in terms of food products entering the country's borders. Chantal Arendse of the Biosafety Directorate in the Department of Agriculture said on Wednesday that while government was treading a fine line between those in favour and those opposed genetically modified organisms (GM organisms), strides were being made in biosafety.

Laut yang dalam dan dingin, atau sumber hidrotermal bersuhu tinggi di daerah vulkanis, adalah tempat teraman bagi kehidupan jasad renik untuk tetap lestari karena jauh dari cengkeraman tangan manusia.

Para ilmuwan dari Australia menemukan jumlah kehidupan di bawah dasar samudra dua kali lipat dibandingkan dengan yang pernah ditemukan sebelumnya. Sampel tanah yang diambil di lepas pantai Newfoundland mengungkap ada mikroba bersel tunggal yang hidup pada suhu tinggi di kedalaman 1.626 meter di bawah dasar laut.
