Ethanol Fallout: Health Risks for Livestock
With Uncle Sam pushing the production of ethanol for fuel, U.S. farmers are planting more corn than at any time since World War II, and garnering premium prices for each harvested bushel. But many livestock operations are getting hit with a double whammy: higher feeds costs and corn-derived feed that’s carrying triple the normal load of fungal poisons.

Alien Pizza, Anyone?
Although many biochemical molecules come in left-handed and right-handed versions, life on Earth uses one version exclusively, and some controversial experiments suggest this preference might not be due to chance.

Compounds pass the smell test
A vile-smelling but versatile class of compounds may find a role in more chemistry laboratories with the introduction of easily made, inoffensive versions. Isonitriles, chemicals characterized by a triple bond between a carbon and a nitrogen atom, are useful in many reactions. But many chemists have shunned them because of their pungency, says Michael C. […]
