    Bad Karma can ruin palm oil crops

    Palm oil producers thought they had licked shortages of edible oil and biofuel in the 1980s, when they learned to make genetically identical copies of high oil-yielding palms. But when the cloned palms matured, some plants made shriveled fruits with very little oil. Exactly how these dry, “mantled” fruits spawned from twins of oil-gushing palms has been a mystery ever since.

    Oil-barren...

    DNA tags mostly deleted in human germ cells

    Mom and dad’s lifestyle may leave less of a mark on future generations than scientists have suspected.

    In the first weeks after conception, some of the cells in human embryos get their genetic blueprints scrubbed clean, conclude three new studies published June 4 in Cell. Those cells, the ones that become sperm or eggs, could beget the tiny embryos’ future offspring.

    The genetic...

    DNA disorganization linked to aging

    Old cells do not go gently into that good night. In people who age prematurely, changes in the way that DNA is tightly packed in cells leads to mayhem that promotes the aging process, researchers have discovered.

    Werner syndrome, a genetic disorder also known as adult progeria, leads to graying hair, cataracts, osteoporosis and other signs of aging in people in their 20s. Researchers...

    Catalog of DNA modifications produces surprises

    A series of fine-tuned maps of DNA packaging in human cells reveal dynamic new views of how the genome’s instructions are carried out to build a person. The maps also offer surprising insights into what goes wrong in diseases such as Alzheimer’s and cancer.

    The maps and discoveries made after examining them are being published February 18 in more than 20 scientific papers in Nature and...
