Genetic clues found for common congenital brain disorder
...uch milder cerebellar abnormalities are common.The hunt for the Dandy-Walker genes began when a child from Kansas with a missing piece of chromosome 3 was found to have DWM and was referred to Dr. Dobyns for an evaluation. Inspired by this clue, Inessa Grinberg, an M.D./Ph.D. student working with Millen a...Study narrows search for genes placing men at increased risk for prostate cancer

In their genome-wide hunt for gene duplications and losses in humans and great apes, Sikela and colleagues have highlighted genomic regions likely to have influenced primate, and in particular human, evolution....'Trap' crop saves Texas cross timbers melon production
...ot right to work.Mitchell had been involved in the hunt for the cause of yellow vine disease since the mid 1990s. In 1991, yellow vine disease made its premier performance in Texas and Oklahoma, striking melon and cantaloupe fields with a vengeance. Some fields were completely wiped out. By the mid-1990s...Hopkins to found first center for comprehensive study of epigenetics

In the hunt for these details, scientists have focused on four RNA building blocks, or nucleotides, deep within the machine that are identical in every species, from bacteria to humans. Because they sit where the protein chain is actually built, these "universal...From algae, weeds and people: new genetic clues to complex obesity syndrome
... to just 688. To see if these data might help the hunt for disease genes, Dutcher contacted Katsanis. In 1999, a Canadian team of researchers had determined that BBS5 was in a particular region of chromosome 2. In 2003 and 2004, Katsanis, the Canadians and their colleagues presented evidence that faulty ...Whales, seals or men? Who stole all the fish?
...Norwegian ships set sail to resume their country's hunt of minke whales, and Canadian hunters are continuing their cull of harp seals, the largest for 50 years. Debates over whether such animals degrade fish stocks have raged for years. Japan and Iceland, for example, continue to press the International ...Teachers turn to Tolkein to explain physics
