    A success for designer life

    Synthetic biologists are scientists who create custom organisms in the lab. Their efforts have just taken a big step forward. They have created the first lab-made yeast chromosome. The advance could lead to entirely synthetic organisms customized to produce food, fuel or medicine.

    Tomatoes’ tasteless green gene

    The tomatoes your great-grandparents ate probably tasted little like the ones you eat today. The fruit used to have more flavor. A lot more flavor. In fact, tomatoes “were once so flavorful that you could take one in your hand and eat it straight away just like we regularly eat apples or peaches,” according to plant scientist Alan Bennett. He belongs to a team of international scientists who now think they know one reason why the fruit has lost so much flavor. Although some unripe tomatoes have a dark green patch near the stem, farmers prefer that their unripe tomatoes are the same shade of green all over. The consistent coloring makes it easier for them to know when the fruit should be picked.
