  Two new studies that could ultimately help with the diagnosis and treatment of leukemia were published in the Sunday edition of the journal Nature Genetics. In the first, a team of scientists from the Center for Cancer Biology (CCB) at the University of Australia and the University of Washington discovered a genetic defect that they says indicates a pre-disposition to contract acute myeloid leukemia and myelodysplasia. According to a University of Washington press release,...

Plants are very sensitive to light conditions because light is their source of energy and also a signal that activates the special photoreceptors that regulate growth, metabolism, and physiological development. Scientists believe that these light signals control plant growth and development by activating or inhibiting plant hormones. New research from Carnegie plant biologists has altered the prevailing theory on how light signals and hormones interact. Their findings could have implications...

Genetic mechanism once thought rare may allow rapid cell production We take our blood for granted, but its creation requires a complicated series of steps, starting with the formation of blood stem cells during early embryonic development, followed by progressive differentiation into the progenitors of red cells, white cells and platelets, and ultimately the full set of blood cells. Now, in the July 9 issue of Cell, researchers at Children's Hospital Boston report a surprising twist in how...

Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
