Data from the research plots on Tumamoc Hill reveal changes in the Sonoran Desert and have been important to key advances in the science of ecology.
Researchers at the University of Arizona’s Tumamoc Hill have digitized 106 years of growth data on individual plants, making the information available for study by people all over the world.
Knowing how plants respond to changing conditions over many decades provides new insights into how ecosystems behave. (more…)
COLLEGE PARK, Md. – You may not know Lee Berger by name, but you may have seen the work of his production teams in many of 2012’s biggest movies: “Django Unchained,” “The Hunger Games,” “Life of Pi” and “Snow White and the Huntsman.”
Berger ’76 is president of the film division of Rhythm & Hues Studios, a Los Angeles-based company that does everything from animating the Chipmunks to creating fantastic worlds (“The Chronicles of Narnia”).
“This is a very competitive industry,” says Berger. “We don’t normally get to pick and choose, and we’re lucky that Ang Lee chose us (for ‘Life of Pi’).” (more…)
A new study in the journal Neuron suggests that the brain uses a different region than neuroscientists had thought to associate objects and locations in the space around an individual. Knowing where this fundamental process occurs could help treat disease and brain injury as well as inform basic understanding of how the brain supports memory and guides behavior.
PROVIDENCE, R.I. [Brown University] — Where are you?
Conventional wisdom in brain research says that you just used your hippocampus to answer that question, but that might not be the whole story. The context of place depends on not just how you got there, but also the things you see around you. A new study in Neuron provides evidence that a different part of the brain is important for understanding where you are based on the spatial layout of the objects in that place. The finding, in rats, has a direct analogy to primate neuroanatomy. (more…)
Hospitals that continue CPR longer have better survival rates from cardiac arrests, according to a study published online Sept. 5 in The Lancet. The findings challenge the assumption that, if a pulse is not restored soon, continuing resuscitation efforts is futile.
The results also showed that patients who recovered after an extended CPR effort were no more likely to suffer brain damage than are patients revived after a shorter effort. (more…)
Researchers have made a major advance in efforts to regenerate damaged hearts. They discovered that transplanted heart muscle cells, grown from stem cells, electrically couple and beat in sync with the heart’s own mucle.
The grafts also reduced the incidence of arrhythmias (irregular heart rhythms) in a guinea pig model of myocardial infarction (commonly known as a heart attack).
This finding from University of Washington-led research is reported in the Aug. 5 issue of Nature. (more…)
