A team of paleontologists has discovered a new dinosaur species they're calling Abydosaurus, which belongs to the group of gigantic, long-necked, long-tailed, four-legged, plant-eating dinosaurs such as Brachiosaurus.

The origins of flowering plants from peas to oak trees are now in clearer focus thanks to the efforts of University of Florida researchers.

For the first time, scientists have sequenced the entire genome of the pea aphid, a notorious horticultural and agricultural pest. The findings reveal the extent of the genetic collaboration of the aphid host with its bacterial symbiont, which may account for some of the extraordinary characteristics of this insect.

Iron containing short nerve branches in the upper beak of birds may serve as a magnetometer to measure the vector of the Earth magnetic field (intensity and inclination) and not only as a magnetic compass, which shows the direction of the magnetic field lines. Already several years ago, the Frankfurt neurobiologists Dr.Gerta Fleissner and her husband Prof. Dr. Günther Fleissner have discovered these structures in homing pigeons and have, in close cooperation with the experimental physicist Dr. Gerald Falkenberg (DESY Hamburg), characterized the essential iron oxides."After we had shown the system of dendrites with distinct subcellular iron-containing compartments in homing pigeons, immediately the question was posed whether similar dendritic systems may be found in other bird species, too", as Gerta Fleissner, the principal investigator, comments. Meanwhile they could describe similar candidate structures in the beaks of various avian species. X-Ray-fluorescence measurements at DESY demonstrated that the iron oxides within these nervous dendrites are identical. These findings were published few days ago in the high-ranking interdisciplinary online journal PlosOne.
