DAVIS, CA -- In peach trees, as in other plants, the energy used to create carbohydrates that support growth and development comes from solar radiation through the process of photosynthesis. Peach tree productivity is therefore dependent on the tree's photosynthetic efficiency and effectiveness in distributing and using carbohydrates. A basic knowledge of carbon assimilation and partitioning concepts at the whole-tree level can aid growers in understanding how peach trees grow and help them adopt cultural practices that maximize production. Carbon assimilation and partitioning ...

RIVERSIDE, Calif. – Ever wondered why flies are attracted to beer? Entomologists at the University of California, Riverside have, and offer an explanation. They report that flies sense glycerol, a sweet-tasting compound that yeasts make during fermentation. "Insects use their taste system to glean important information about the quality and nutritive value of food sources," said Anupama Dahanukar, an assistant professor of entomology, whose lab conducted the research. "Sugars signal high nutritive value to flies, but little is known about which chemical cues flies use ...

COMO, ITALY -- Traditionally addressed through hand-weeding and/or herbicide application, controlling weeds is one of most costly operations in nursery production. Increased labor costs have made hand-weeding prohibitive as the sole method of weed control, and although herbicides may be effective and less expensive, non-target herbicide loss can be as high as 86% and can harm the environment. To address the economic and environmental impact of weed problems, nursery producers are looking for more sustainable and cost-efficient techniques to control weeds in container-grown ...

AMHERST, Mass. – New, high-precision equipment orbiting Earth aboard the Hubble Space Telescope is now sending such rich data back to astronomers, some feel they are crossing the final frontier toward understanding galaxy evolution, says Todd Tripp, leader of the team at the University of Massachusetts Amherst. Galaxies are the birthplaces of stars, each with a dense, visible central core and a huge envelope, or halo, around it containing extremely low-density gases. Until now, most of the mass in the envelope, as much as 90 percent of all mass in a galaxy, was undetectable ...

Vultures in South Asia were on the brink of extinction until Lindsay Oaks and Richard Watson, from The Peregrine Fund in the US, undertook observational and forensic studies to find out why the number of birds was falling so rapidly. They discovered the vultures were being poisoned by residues of an anti-inflammatory drug (diclofenac) used in cattle and other livestock, whose carcasses they feed on. The work is presented in a chapter of the new book, 'Wildlife Ecotoxicology - Forensic Approaches,' published by Springer. According to the authors: "The story is far from ...

National Science Foundation- (NSF) funded researchers may have at last answered a 50 year-old conundrum. They may now know how Antarctica's Gamburtsev Subglacial Mountains were formed, which has been a question for scientists since their discovery in 1958. Researchers involved in a highly complex research deployment to the Gamburtsev Subglacial Mountains, a centerpiece of the 2007-2009 International Polar Year (IPY), conclude the mountains formed as a result of multiple tectonic events, rather than a single event. This week's journal Nature reports the findings. According ...

A new, unprecedented national survey of African American Catholics by University of Notre Dame researchers reveals several significant insights into individual religious engagement and identifies several notable demographic trends facing the church. The survey was sponsored by the National Black Catholic Congress and Notre Dame's Institute for Church Life and Office of the President. Notre Dame social scientists Darren W. Davis and Donald B. Pope-Davis, who coauthored the report, set out to test the validity of anecdotal accounts that African American Catholics were ...

A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago, according to two Princeton University reports that reject the prevailing theory that the extinction was caused by a single large meteorite. Princeton-led researchers found that a trail of dead plankton spanning half a million years provides a timeline that links the mass extinction to large-scale eruptions of the Deccan Traps, a primeval volcanic range in western ...

HUNTINGTON, W.Va. – Recent studies conducted at Marshall University have demonstrated that nanoparticles of cerium oxide -- common diesel fuel additives used to increase the fuel efficiency of automobile engines -- can travel from the lungs to the liver and that this process is associated with liver damage. The data in the study by Dr. Eric R. Blough and his colleagues at Marshall's Center for Diagnostic Nanosystems indicate there is a dose-dependent increase in the concentration of cerium in the liver of animals that had been exposed to the nanoparticles, which are ...

COLUMBIA, Mo. – More than 20 years ago, Charles Borduin, a University of Missouri researcher, developed a treatment for juvenile offenders that has become one of the most widely used evidence-based treatments in the world. Now, he has found that the treatment continues to have positive effects on former participants more than 20 years after treatment. Throughout the course of his career, Borduin, professor of psychological sciences in the College of Arts & Science, has pioneered the treatment called Multisystemic Therapy (MST) as a way to prevent serious mental health ...

KANSAS CITY, MO -- Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells. Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division. In a study published in the Nov. 17, 2011 issue of PLoS Genetics, ...

WASHINGTON, November 17, 2011 -- Factors such as low hemoglobin levels, increased systolic blood pressure, and male gender are linked to a higher risk of silent cerebral infarcts (SCIs), or silent strokes, in children with sickle cell anemia (SCA), according to results from a large, first-of-its-kind study published online today in Blood, the Journal of the American Society of Hematology (ASH). Silent strokes are the most common form of neurological injury found in SCA, with more than 25 percent of children with the disorder suffering a SCI by age six,1 and nearly 40 ...

While shorter days and colder weather move many of us to hunker under the covers, researchers who spent their summers in fieldwork are more likely to be hunched over microscopes and curled over keyboards, scrutinizing samples and crunching data from their summer's labors. One such researcher is marine biologist William Gilly, who spent a month last summer in Mexico's Sea of Cortez tracking the sometimes-elusive Humboldt squid. Researchers from several universities were on the voyage. Gilly is in the second year of a quest to understand the surprisingly strong impact ...

LIVERMORE, Calif. -- In order to separate human-caused global warming from the "noise" of purely natural climate fluctuations, temperature records must be at least 17 years long, according to climate scientists. To address criticism of the reliability of thermometer records of surface warming, Lawrence Livermore National Laboratory scientists analyzed satellite measurements of the temperature of the lower troposphere (the region of the atmosphere from the surface to roughly five miles above) and saw a clear signal of human-induced warming of the planet. Satellite measurements ...

ITHACA, N.Y. - Like a shadowy character just hidden from view, a mystery atom in the middle of a complex enzyme called nitrogenase had long hindered scientists' ability to study the enzyme fully. But now an international team of scientists led by Serena DeBeer, Cornell assistant professor of chemistry and chemical biology, has pulled back the curtain using powerful synchrotron spectroscopy and computational modeling to reveal carbon as the once-elusive atom. The research was published online Nov. 17 in the journal Science. "For chemists, one of the first steps you ...
