Most of the many factors for determining leaf size turn out to put on the brakes, rather than promote growth

The tips of two adult fruit fly testes, viewed under a confocal microscope, are filled with dividing germ cells (green). About one quarter of these germ cells die by an alternative death pathway called germ cell death (pink and red)

How does a helpful virus often used for gene therapy break into cells?

“Deregulation scores” of hundreds of brain tumor patients: Each row corresponds to a pathway (that is, a biochemical process), and each column to a sample taken from a patient. Every colored spot stands for a number – the value of the “deregulation score” of the corresponding pathway, as determined for a particular patient. Dark blue stands for the activity of the pathway in normal brain tissue, whereas dark red indicates a high level of deviation from normal behavior. The clearly distinct group of normal b
