Changes in Australian ecosystems tied to arrival of exotic animals
...al Australia since European colonization, the team derived
proportions of grasses compared to bushes and trees in the diet of emus that laid their eggs between 300 and 14,000 years ago. The team then compared eggshells collected in the past 25 years with those going back to the last glacial maximum 15,000 y...

UCSF study of HIV patients identifies interleukin-7 as a key factor in controlling T-cells
...ls. T-cells are disease fighting white blood cells derived
from the thymus that are essential for a healthy immune system. Infection with HIV destroys T-cells and decreases T-cell production resulting in immunodeficiency. The researchers found that the level of interleukin (IL)-7, a cytokine that stimulate...
New species of early bird discovered in Mongolia by team of research scientists
...fore Apsaravis. The name of this type specimen is derived
from the Sanskrit Apsara, or winged consorts prominent in Buddhist and Hindu art, and the Greek aves, or bird; Ukhaana refers to Ukhaa Tolgod. Apsaravis ukhaana is part of the collection of the Mongolian Academy of Sciences, to which it will be retu...

A bizarre new predatory dinosaur unearthed on Madagascar
...The first part of the name of this new dinosaur is derived
from masiaka, the Malagasy word for "vicious", and sauros, which is Greek for "lizard". The second, part, knopfleri, honors singer/songwriter Mark Knopfler, lead singer of the musical group Dire Straits. The reason for the reference to Knopfler is t...

UCSF-led study points to pivotal, early event in cancer development
... The researchers placed the two cell types, both derived
from normal breast tissue, in separate culture dishes to observe their growth patterns. The differences were quickly apparent. The fibroblasts displayed the classic characteristics of normal cell behavior. They maintained an active cell cycle for s...
UW researchers show that the human genome is helpless in the face of chocolate

Plants as plants: gene could convert crops to plastics factories
...lastics are produced by making chains of compounds derived
from petroleum. Scientists call these chains polymers, and the individual molecules that form the chain are called monomers. One reason scientists are interested in making plastics from plants is that plants produce an amazing array of compounds that...
Rat study shows high-fat diet impairs concentration and memory
...o three dietary groups -- those fed high-fat foods derived

Scientists detail parts of biological motor' key to cell life
... Though the research was conducted on proteins derived
from the fruit fly, the findings have implications for humans as well, Barbar noted. "LC8 is virtually the same in humans as it is in flies, so it must be so important that it didn't change through evolution," she said....
