  • Drought may take toll on Congo rainforest, NASA satellites show
    A new analysis of NASA satellite data shows Africa's Congo rainforest, the second-largest tropical rainforest in the world, has undergone a large-scale decline in greenness over the past decade. Scientists use the satellite-derived "greenness" of forest regions as one indicator of a forest's health. While this study looks specifically at […]
  • Rural microbes could boost city dwellers' health, study finds
    The greater prevalence of asthma, allergies and other chronic inflammatory disorders among people of lower socioeconomic status might be due in part to their reduced exposure to the microbes that thrive in rural environments, according to a new scientific paper.
  • Male or female? First sex-determining genes appeared in mammals some 180 million years ago
    The Y chromosome, which distinguishes males from females at the genetic level, appeared some 180 million years ago. It originated twice independently in all mammals. Scientists have managed to date these events that are crucial for both mammalian evolution and our lives, because the Y chromosome determines whether we are born as a boy or girl.
  • Picky male black widow spiders prefer well-fed virgins
    New research shows that male black widow spiders prefer their female mates to be well-fed virgins -- a rare example of mate preference by male spiders. The study found they can tell whether a potential mate is well-fed and unmated by pheromones released by females.
  • Enzymes that help fix cancer-causing DNA defects disovered
    An important enzyme pathway that helps prevent new cells from receiving too many or too few chromosomes, a condition that has been directly linked to cancer and other diseases, has been discovered by researchers. Near the end of cell division, the enzyme Cdc14 activates Yen1, an enzyme that ensures any breaks in DNA are fully repaired before the parent cell […]
