Public Release: 9-Jun-2009
 Journal of the American Society for Mass Spectrometry{DISSERTATION} VBI researchers develop new method for breast cancer biomarker discovery Three researchers from the Virginia Bioinformatics Institute at Virginia Tech have developed and evaluated a new one-step bioanalytical approach that allows them to profile in detail complex cellular extracts of proteins. The method has allowed the scientists to look at how the levels of proteins change in breast cancer cells when they are treated with hormones or cancer drugs like tamoxifen.

Cancer Research{DISSERTATION} Colon cancer screening technique shows continued promise in new study Recent clinical trials show that a new colon cancer screening technique created by Northwestern University researchers has a high enough sensitivity that it could potentially be as or more successful than a colonoscopy in screening for colon cancer.

Journal of Morphology{DISSERTATION} Discovery raises new doubts about dinosaur-bird links Researchers at Oregon State University have made a fundamental new discovery about how birds breathe and have a lung capacity that allows for flight -- and the finding means it's unlikely that birds descended from any known theropod dinosaurs.

American Astronomical Society Meeting Astrophysical Journal Letters{DISSERTATION} Red giant star Betelgeuse is mysteriously shrinking The red supergiant star Betelgeuse, which is so large it would extend to Jupiter's orbit in our solar system, has steadily shrunk over the past 15 years, according to UC Berkeley physicists. Since 1993, its radius has gone down by 15 percent, equivalent to the radius of Venus's orbit. This conclusion comes from unique laser interferometer observations by laser inventor and Nobel Laureate Charles Townes and his colleague, Edward Wishow.

Proceedings of the Royal Society B{DISSERTATION} 'Weedy' bird species may win as temperatures rise Climate change is altering North American winter bird communities in ways that models currently favored by ecologists fail to predict. Current distributions of animals among different climate zones suggest that, as habitats warm, numbers of species will increase and that those species will be smaller in size and restricted to narrower geographic ranges, but only one of those predictions has held for North American birds over the past quarter century.

Molecular Ecology{DISSERTATION} Study shows animal mating choices more complex than once thought When female tiger salamanders choose a mate, it turns out that size does matter -- tail size that is -- and that's not the only factor they weigh. Findings of a Purdue University study show that animals make more complex decisions about choosing mates than once thought.

American Astronomical Society Meeting{DISSERTATION} To 300 million light years, and beyond -- a new way to measure cosmic distances Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement technique. They discovered that a rare type of giant star, often overlooked by astronomers, could make an excellent signpost for distances up to 300 million light years -- and beyond.

Geology{DISSERTATION} Fossil bone bed helps reconstruct life along California's ancient coastline Sharktooth Hill near Bakersfield, Calif., is the home of the most extensive marine bone bed in the world, a 100-square-mile layer of shark, seal, ray, whale, turtle and fish bones. A UC Berkeley professor and five Berkeley Ph.D.s have analyzed the 15-million-year-old fossils to decipher the history of what used to be the California coastline, reconstructing a 700,000-year period of warming climate and teaming sea life.

Journal of Paleontology{DISSERTATION} Fossil teeth of browsing horse found in Panama Canal earthworks Rushing to salvage fossils from the Panama Canal earthworks, Aldo Rincon, paleontology intern at the Smithsonian Tropical Research Institute, unearthed a set of fossil teeth. Bruce J. MacFadden, curator of vertebrate paleontology at the Florida Museum of Natural History, University of Florida in Gainesville, describes the fossil as Anchitherium clarencei, a three-toed browsing horse, in the May 2009 issue of the Journal of Paleontology.

But what if you did not have to change the search terms yourself? What if the search engine could do that for you?

Nature{DISSERTATION} Caltech scientists create nanoscale zipper cavity that responds to single photons of light Physicists at the California Institute of Technology (Caltech) have developed a nanoscale device that can be used for force detection, optical communication and more. The device exploits the mechanical properties of light to create an optomechanical cavity in which interactions between light and motion are greatly strengthened and enhanced. These interactions, notes Oskar Painter, associate professor of applied physics at Caltech and the principal investigator on the research, are the largest demonstrated to date.

Science{DISSERTATION} At long last, how plants make eggs Scientists at the University of California-Davis, have discovered that a plant hormone called auxin is responsible for development of the egg cell in a plant's embryo sac. In unraveling this fundamental issue in plant biology, the work provides the first definitive report of a plant hormone acting as a morphogen and offers tantalizing new insights into the evolutionary pathway that flowering plants took 135 million years ago when they split off from gymnosperms.

Current Biology{DISSERTATION} 'Pelvis has left the building' New research shows that when two species of stickleback fish evolved and lost their pelvises and body armor, the changes were caused by different genes in each species. That surprised researchers, who expected the same genes would control the same changes in both related fish. The findings shed new light on how evolution produces diversity in nature, and on the evolution of limb loss.

Science{DISSERTATION} New proxy reveals how humans have disrupted the nitrogen cycle Researchers from Brown University and the University of Washington have found a new proxy to measure the impact of fossil fuel emissions on the global nitrogen cycle. The scientists use nitrogen isotopes found in a Greenland ice core to link nitrates to the rise in nitric oxides since the industrial period. The research also shows the greatest change in the isotope ratios occurred between 1950 and 1980, following a rapid increase in fossil fuel burning. Results are published in Science.

{DISSERTATION} Does service learning produce better engineers, attract women to the field? Tufts' School of Engineering researchers have launched a study to determine the extent to which service-learning might help engineering programs attract and retain students, particularly women. The research, which is funded by a $500,000 grant from the National Science Foundation, will address two prevailing, but unproven, beliefs about service-learning in the engineering classroom.
