Agriculture's origin may be hidden in 'invisible' clues
As scientists attempt to learn about the origins of agriculture in the New World, they're focusing on what, for the most part, is invisible - microscopic plant crystals, tiny starch grains and fossilized pollen. These microscopic plant traces reliably record the earliest use of domesticated plants, says Texas A&M University anthropologist Vaughn Bryant, who is also the director the university's palynology laboratory.

Scientists unravel complicated genetic disease in one fell swoop
Scientists consider themselves lucky when an inherited disease is due to a single gene, like Huntington disease, for example. But most inherited diseases arise from a number of genetic changes that add up to trouble, making it difficult for geneticists to find everything that's to blame. In the April 15 advance online edition of Nature Genetics, scientists report that three regions -- parts of chromosomes 3, 10 and 19 -- are crucial for causing a complex genetic disease and together explain its complicated inheritance pattern.
