for cuticle tanning opens up possibilities of targeting this protein as a way of weakening the beetle's physical defenses against mechanical, chemical and biological injuries, Muthukrishnan said. Better insecticides could be developed as a result of ...
Relic of life in that Martian meteorite? A fresh look
...s important because magnetite is known to act as a catalyst
in the formation of MMC. Macromolecular carbon present within the carbonate globules in ALH84001 may represent the first evidence of non-biological synthesis of organic molecules on Mars. "Although we haven't settled the debate on whether evidence ...
