While mole infestations are oftentimes commonplace on farmlands, and workers would gladly do anything to eliminate the threat, scientists are still puzzled by these subterranean creatures. The animals feature pinhead-sized eyes that are useless, given that they are covered by a thin layer of skin. This raises the que... |

One of the fundamental truths about our bodies is that most cells need oxygen to survive. We inhale the chemical each breath we take, then take it to our lungs, where the precious molecules are then attached to hemoglobin, one of the most important proteins we have. Hemoglobin itself is housed on red blood cells, ele... |

Experts from the Monash Immunology and Stem Cell Laboratories have recently managed to bring the goal of creating fully functional, mature red blood cells from stem cells a bit closer. They designed a line of human embryonic stem cells (hESC) to become fluorescent only when it is differentiated into RBCs, and then wa... |

This is the champ diver of the birds' world, not just the largest penguin. A new study, published in the "Journal of Experimental Biology", attempts to decode the secret of why emperor penguins can dive down to 1,850 ft (565 m) for up to 23 minutes (with an average of 6 minutes) with a sole breath: a special hy... |

We know that hemoglobin, the iron-rich pigment of the blood's red cells is the carrier of the oxygen from lungs to tissues and carbon dioxide from tissues to lungs. Now, a team from Wake Forest University, the National Institute of Health and other institutions has found, in a research published online on Nov. 4... |

The feces of most vegetarian mammals are greenish, due to the plant's green pigment called chlorophyll, which cannot be digested. Birds' feces are whitish, as they are covered in dry urine, made of white uric salts. When carnivores eat bones, their feces can result whitish due to the mineral salts from the ... |
