eScholarship@UMMS is a digital repository offering worldwide access to the research and scholarly output of the University of Massachusetts Medical School community. The goal is to bring together all of the University's research under one umbrella, in full text whenever possible, in order to showcase, preserve, and provide access to that research. eScholarship@UMMS is administered by the Lamar Soutter Library.

Patricia Chocano-Bedoya (University of Massachusetts, Amherst) et al. American Journal of Epidemiology, doi: 10.1093/aje/kws363 "Einen Haken hat die segensreiche Wirkung von Eisen und Zink allerdings: Eine signifikante Wirkung trat nur dann auf, wenn die Frauen mehr davon eingenommen hatten, als es der eigentlich empfohlenen Tagesdosis entspricht. "Weitere Studien sind deshalb dringend nötig, um festzustellen, ob die Vorteile einer höheren Eisen- und Zinkgabe die Risiken aufwiegen", betonen die Forscherinnen. Ebenfalls weiter untersucht werden muss ihrer Ansicht nach, warum ein weiteres Mineral, Kalium, PMS sogar zu fördern scheint. Selbst Frauen, die über längere Zeit knapp weniger als die empfohlene Tagesdosis von 4.700 Milligramm Kalium aufgenommen hatten, entwickelten häufiger Beschwerden als Teilnehmerinnen mit sehr niedrigen Kaliumwerten. Warum das so ist, müsse aber noch geklärt werden, sagen Chocano-Bedoya und ihre Kolleginnen."

Harald Ott: Scientists at the Massachusetts General Hospital in Boston have created a bioengineered kidney that can be transplanted back into a rat, where it begins making urine"

A team of scientists from the California Institute of Technology, Princeton, Drexel University, and the Massachusetts Institute of Technology have formed the first professional scientific organization based entirely in virtual worlds. Meta Institute for Computational Astrophysics (MICA) conducts professional seminars and popular lectures, among other events, for its growing membership.

The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to double by mid-century and triple by the end of the century. Even in light of unprecedented conservation, the additional energy needed is simply not attainable from long discussed sources these include nuclear, biomass, wind, geothermal and hydroelectric. The global appetite for energy is simply too much. Petroleum-based fuel sources (i.e., coal, oil and gas) could be increased. However, deleterious consequences resulting from external drivers of economy, the environment, and global security dictate that this energy need be met by renewable and sustainable sources. The dramatic increase in global energy need is driven by 3 billion low-energy users in the non-legacy world and by 3 billion people yet to inhabit the planet over the next half century. The capture and storage of solar energy at the individual level personalized solar energy drives inextricably towards the heart of this energy challenge by addressing the triumvirate of secure, carbon neutral and plentiful energy. This talk will place the scale of the global energy issue in perspective and then discuss how personalized energy (especially for the non-legacy world) can provide a path to a solution to the global energy challenge. Daniel G. Nocera is the Henry Dreyfus Professor of Energy at the Massachusetts Institute of Technology, Director of the Solar Revolutions Project and Director of the Eni Solar Frontiers Center at MIT. His group pioneered studies of the basic mechanisms of energy conversion in biology and chemistry. He has recently accomplished a solar fuels process that captures many of the elements of photosynthesis outside of the leaf. This discovery sets the stage for a storage mechanism for the large scale, distributed, deployment of solar energy. He has b

Traditional methods of transmitting data, such as fibre optics or laser-based radar, require roughly 100 photons to transmit a single bit of data. Now a team led by Saikat Guha at Raytheon BBN Technologies in Cambridge, Massachusetts, say they can transmit 10 bits on a single photon - a 1000-fold improvement.

An immune-suppressing drug called rapamycin could possibly treat Hutchinson-Gilford progeria syndrome (HGPS), a rare genetic disease that causes premature aging, and advance biological understanding of the normal aging process, according to researchers from the National Human Genome Research Institute (NHGRI) at the National Institutes of Health, the University of Maryland and Massachusetts General Hospital. Progeria is a genetic disorder characterized by dramatic premature aging. "Progerin that causes progeria also accumulates, although in very small amounts, in normal aging," said Dimitri Krainc, M.D., Ph.D., associate professor of neurology at Harvard Medical School. "However, if rapamycin proves to have beneficial effects in lifespan in humans it is safe to assume that it will not be just because it may clear progerin from cells, but also because it clears other toxic products that accumulate during aging."
