Study: Predatory dinosaurs had bird-like pulmonary system

...ick O'Connor, an assistant professor of biomedical sciences at Ohio University's College of Osteopathic Medicine and lead author on the study, which was funded in part by the National Science Foundation. O'Connor and collaborator Leon Claessens of Harvard University visited museums in New York, Berkeley, Chi...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

.... Epstein, an associate professor of environmental sciences at the University of Virginia and a co-author of the new study. The scientists determined that the increasing summer temperatures in northern Alaska could not be attributed to regional atmospheric circulation patterns or to a reduction in sea ice in ...

Ants, not evil spirits, create devil's gardens in the Amazon rainforest, study finds

...n, notes Gordon, associate professor of biological sciences at Stanford. "The system harnesses two fundamental tools:formic acid, which many ant species use for other purposes, and the basic circulatory system of all vascular plants," she says. A census of the rainforest from 2002 to 2004 revealed that devil...

Skull study sheds light on dinosaur diversity

... said Wilson, an assistant professor of geological sciences and an assistant curator at the University of Michigan Museum of Paleontology. But as prevalent as titanosaurs were, they left behind surprisingly few skulls. Paleontologists have found plenty of other titanosaur bones, providing a picture of a group...

Genetic variation alters response to common anti-clotting drug

...he University of Washington's department of genome sciences and first author of the paper, wanted to better understand the genetic basis for variability in warfarin response. "If you want to predict dose, you need to know more about the genes that control variability," explained Rieder. The team focused on a...

Birds and bats sow tropical seeds

... restoration ecology and a professor of biological sciences at UIC, will lead the multi-year test, funded initially by a five-year, $500,000 grant from the National Science Foundation. Co-investigators include Christina Martinez-Garza, a biologist on the faculty of the Autonomous University of Morelos in Mexi...

UW-Madison scientists zero in on drugs' sweet spots

...y of Wisconsin-Madison professor of pharmaceutical sciences Jon S. Thorson, describes a series of experiments that boosted the cell-killing potency and tumor specificity of the drug, derived from the foxglove plant and used to stimulate the heart. The drug is suspected to have anti-cancer properties, but its ...

Firefly protein lets researchers monitor molecule linked to cancer

...okinetics," says Piwnica-Worms in reference to the sciences that study the effects, distribution and dissipation of drugs. "Traditionally the only ways we could do those kinds of studies were either to test for levels of the drug in the blood or to label the drug with a radioactive tracer. "In the case of NF...

Micro RNAs play role in egg making

...Jonathan Minden, associate professor of biological sciences at Carnegie Mellon and one of the paper's authors. The findings will be published online the week of Aug. 8 by the Proceedings of the National Academy of Sciences (PNAS). "If miRNAs are missing from a developing egg, then it fails to develop to ter...

UW scientists report a new method to speed bird flu vaccine production

...nfluenza expert and a professor of pathobiological sciences in UW-Madison's School of Veterinary Medicine. Monkey kidney cells are used routinely for generation of seed strains for vaccine production because they are not known to carry any unknown infectious agents and do not cause tumors. According to Kawa...

Fighting malaria by manipulating mosquitoes' sense of smell

...ence J. Zwiebel, associate professor of biological sciences at Vanderbilt, who is the lead investigator on the project. The mixtures developed in the project could be useful against other disease-carrying mosquitoes, such as those that spread dengue fever and those that carry the West Nile virus. In addition...

Study hints at role of stem cell genes in testicular, breast cancers

...ofessor of obstetrics, gynecology and reproductive sciences and co-director of the UCSF Human Embryonic Stem Cell Center. "This is the first indication that these genes are markers of breast cancer. The finding might lead to information about where breast cancers come from," Clark adds. "Are they derived fr...

Delaware scientists make significant advance in study of small RNAs

...e C. Meyers, assistant professor of plant and soil sciences in the College of Agriculture and Natural Resources. To identify the small RNAs, the scientists used the transcriptional profiling technology called Massively Parallel Signature Sequencing (MPSS), which was developed by Solexa Inc. of Hayward, Cali...

University of Delaware researchers develop cancer 'nanobomb'

...e result of interdisciplinary research. "Different sciences come together to make this work," he said, citing cancer biology, physics, electrical and computer engineering and chemistry. "Interdisciplinary research provides for fresh perspectives and brings about new ideas, which is probably the way to go in t...

MIT researcher finds neuron growth in adult brain

...g; Wei-Chung Allen Lee, an MIT brain and cognitive sciences graduate student; and Hayden Huang, a mechanical engineering research affiliate -- used a method called two-photon imaging to track specific neurons over several weeks in the surface layers of the visual cortex in living mice.
