A team of scientists, including several from the Smithsonian Institution, discovered that leaves of flowering plants in the world's first rainforests had more veins per unit area than leaves ever had before. They suggest that this increased the amount of water available to the leaves, making it possible for plants to capture more carbon and grow larger. A better plumbing system may also have radically altered water and carbon movement through forests, driving environmental change. "It's fascinating that a simple leaf feature such as vein density allows one to study plant ...

CINCINNATI—Hepatitis B virus (HBV) continues to be a major health issue in the United States despite prevention strategies. Now, research at the University of Cincinnati (UC) provides evidence that current prevention and screening standards are worth the cost and may even need expansion to include more of the population, further helping prevent the spread of this life-threatening disease. The findings are published in the May 3, 2011 advance online edition of the journal Clinical Infectious Diseases. Mark Eckman, MD, UC Health physician and professor of medicine, ...

PROVIDENCE, R.I. [Brown University] — The cactus, stalwart of the desert, has quite a story to tell about the evolution of plant communities found the world over. In a paper published in the early edition of the Proceedings of the National Academy of Sciences, Brown University biologists and colleagues have discovered that the rapid speciation of cacti occurred between 5 and 10 million years ago and coincided with species explosions by other succulent plant groups around the world. The researchers propose that a prolonged dry spell and possibly lower levels of atmospheric ...

SEATTLE – Many patients who undergo bone marrow or blood stem cell transplantation to treat blood cancers or a "pre-leukemic" condition called myelodysplasia experience a decline in mental and fine motor skills due to the toll of their disease and its treatment. A new study led by researchers at Fred Hutchinson Cancer Research Center, published in the May 2, 2011 online edition of the Journal of Clinical Oncology, found that overall, these effects are largely temporary and that most patients can expect a return to normal motor and memory function within five years. However, ...

Many people reach toward the back of the fresh-produce shelf to find the freshest salad greens with the latest expiration dates. But a study led by U.S. Department of Agriculture (USDA) scientists may prompt consumers to instead look for packages that receive the greatest exposure to light--usually those found closest to the front. The study was led by postharvest plant physiologist Gene Lester while at the Agricultural Research Service (ARS) Crop Quality and Fruit Insects Research Unit in Weslaco, Texas. ARS is USDA's chief intramural scientific research agency. Lester ...

WESTERVILLE, OH – Imagine a battlefield medic or emergency medical technician providing first aid with a special wad of cottony glass fibers that simultaneously slows bleeding, fights bacteria (and other sources of infection), stimulates the body's natural healing mechanisms, resists scarring, and—because it is quickly absorbed by surrounding tissue — may never have to be removed in follow-up care. Or, imagine diabetics with hard-to-heal wounds finding a source of relief from the battle against infections and limb amputation. Those scenarios are the hope of the developers ...

COLUMBUS, Ohio – A team of researchers is beginning to see exactly what the response to threats looks like in the brain at the cellular and molecular levels. This new information, including the discovery that a model of social stress can increase inflammation among brain cells, should provide new insight into how the stress response affects inflammatory and behavioral responses. It may also provide new targets for drugs treatments in the continuing struggle to curtail depression and anxiety. Scientists from Ohio State University's Institute of Behavioral Medicine ...

PROVIDENCE, R.I. – A new study from Rhode Island Hospital has found that more than one in 10 catheter-related bloodstream infections due to Staph aureus in hospitalized adults are caused by infected peripheral venous catheters (PVC).

The study is published in the journal Infection Control and Hospital Epidemiology and is now available online in advance of print. Senior author Leonard Mermel, ...

This release is available in French. Montreal, May 3, 2011 – Most Canadian teenagers are expected to make their own decisions, while Chinese adolescents are still heavily influenced by their parents, according to a study published in the Journal of Business Research. Led by Concordia University and the University of Texas at Arlington researchers, the investigation found child-rearing practices appear to impact teen outlooks and decision-making patterns differently across cultures. Why? Parenting varies in both countries, since Canada is an individualist culture and ...

Boston- Researchers from Boston University School of Medicine and Boston Medical Center have found that by adding one family physician per 1,000, or 100 per 100,000, could reduce hospital readmission costs by $579 million per year, or 83 percent of the Patient Protection and Affordable Care Act (ACA) target. These findings currently appear on the website of the "Robert Graham Center," a primary care think tank. Growth of family physicians has fallen over the last decade due to payment disparities and other strong incentives for subspecialization, and lack of accountability ...

HOUSTON -- (May 3, 2011) -- A Rice University-led team of physicists this week offered up one of the first theoretical explanations of how two dissimilar types of high-temperature superconductors behave in similar ways. The research appears online this week in the journal Physical Review Letters. It describes how the magnetic properties of electrons in two dissimilar families of iron-based materials called "pnictides" (pronounced: NICK-tides) could give rise to superconductivity. One of the parent families of pnictides is a metal and was discovered in 2008; the other ...

CAMBRIDGE, Mass. -- MIT chemical engineers have designed a new type of drug-delivery nanoparticle that exploits a trait shared by almost all tumors: They are more acidic than healthy tissues. Such particles could target nearly any type of tumor, and can be designed to carry virtually any type of drug, says Paula Hammond, a member of the David H. Koch Institute for Integrative Cancer Research at MIT and senior author of a paper describing the particles in the journal ACS Nano. Like most other drug-delivering nanoparticles, the new MIT particles are cloaked in a polymer ...
