URBANA – Although advances in agronomy, breeding, and biotechnology have dramatically increased corn grain yields, soil test values indicate that producers may not be supplying optimal nutrient levels. Moreover, many current nutrient recommendations, developed decades ago using outdated agronomic management practices and lower-yielding, non-transgenic hybrids, may need adjusting. Researchers with the University of Illinois Crop Physiology Laboratory have been re-evaluating nutrient uptake and partitioning in modern corn hybrids. "Current fertilization practices may ...

A new study with college roommates shows that a particular style of thinking that makes people vulnerable to depression can actually "rub off" on others, increasing their symptoms of depression six months later. The research, from psychological scientists Gerald Haeffel and Jennifer Hames of the University of Notre Dame, is published in Clinical Psychological Science, a journal of the Association for Psychological Science. Studies show that people who respond negatively to stressful life events, interpreting the events as the result of factors they can't change and ...

'Keep it simple' is a good rule of thumb when designing biocontrol programs to combat weeds and invasive plants, according to a meta-analysis of studies by UBC biodiversity experts. Biocontrol programs use an invasive plant's natural enemies (insects and pathogens) to reduce its population. Most biocontrol programs combine many different enemies – typically about three different species, but sometimes as many as 25 – with the hope that at least one will prove effective. But more isn't necessarily better. Some combinations of enemy species can actually end up competing ...

A new report on the potential effects of climate change on NOAA's Olympic Coast National Marine Sanctuary uses existing observations and science-based expectations to identify how climate change could affect habitats, plants and animals within the sanctuary and adjacent coastal areas. It also outlines new management recommendations for the sanctuary, and sanctuary officials called it the first step toward addressing them. They also said the report issued by the sanctuary, Climate Change and the Olympic Coast National Marine Sanctuary: Interpreting Potential Futures, ...

A study just published in the Journal of Marine Biology sheds new light on the relatively rare but occasionally recorded presence of white sharks in waters surrounding the Hawaiian Islands, and suggests a new method to help distinguish between white sharks and close relatives, such as mako sharks. The paper, titled "Occurrence of White Sharks in Hawaiian Waters", was written by Kevin Weng of the University of Hawai'i – Manoa's School of Ocean and Earth Science and Technology (SOEST) and Randy Honebrink of the Hawai'i DLNR Division of Aquatic Resources (DAR). According ...

Numerous epidemiologic studies have shown that a diet high in salt is associated with an increased risk of gastric cancer. Now Timothy L. Cover and colleagues of Vanderbilt University show that high dietary salt combined with infection by the ulcer-causing bacterium Helicobacter pylori greatly increases the risk of cancer. The study was published ahead of print in the journal Infection and Immunity. In the study, the researchers infected Mongolian gerbils with H. pylori. One set of gerbils received a regular diet; the other, a high salt diet. At the end of the experiment ...

The most common cause of lower respiratory tract infections in infants and young children, respiratory syncytial virus (RSV), can be transferred during pregnancy to an unborn baby, according to Cleveland Clinic Children's Hospital research published online this week in the journal PLOS ONE. In animal models, the study shows that RSV is able to spread across the placenta from the respiratory tract of the mother to the fetus, and is present in the lungs after birth, throughout development and into adulthood. RSV is considered the primary cause of infant pneumonia and has ...

Adding "chemical shift" techniques to MRI can help differentiate clear cell renal cell carcinoma from other types of renal cell cancer, a new study shows. That differentiation can help physicians better determine treatment for these patients. The study, conducted at Massachusetts General Hospital in Boston, included 156 patients with proven renal cell cancer. Clear cell renal carcinoma contains microscopic areas of fat, which is not seen on conventional imaging, said Dr. Azadeh Elmi, lead author of the study. "Chemical shift MRI enables us to quantify even small amounts ...

2D plus 3D breast imaging increases cancer detection rates by 11%, and could be particularly useful in detecting cancer in women with dense breasts, a new study suggests. Researchers at Yale University Smilow Cancer Hospital in New Haven, CT, reviewed the screening mammograms of 14,684 patients. Forty-two cancers were found in 8,769 patients who had only 2D imaging (a cancer detection rate of 4.8 per 1,000), said Dr. Jaime Geisel, a lead author of the study. Thirty-two cancers were found in the group that had 2D plus 3D (tomosynthesis) imaging, for a cancer detection ...

One view 3D breast screening (tomosynthesis) means less radiation dose and about five seconds less compression, but a study from Yale University, New Haven, CT, found that obtaining both views is necessary to help ensure that a cancer won't be missed. There are practices in Europe that have reported performing only a single view, specifically the mediolateral oblique (MLO) view, said Dr. Noa Beck, the lead author of the study. Two views are standard in the U.S. for 3D breast screening; "we wanted to see if one view would be sufficient," she said. Seven breast imagers ...

One venous puncture, rather than two, is a safe and effective approach to intravascular ultrasound-guided inferior vena cava filter placement in critically-ill patients, a new study shows. Inferior vena cava filter placement is done to prevent or treat pulmonary emboli or deep venous thrombosis. "The majority of institutions use a dual venous puncture technique, while we use a single venous puncture technique," said Dr. Andrew Gunn, of Massachusetts General Hospital in Boston. "We were interested to know if the different approaches affected technical success, clinical ...

Boston – More than three years after the United States Preventive Services Task Force (USPSTF) recommended against routine mammogram screening for women between the ages of 40 and 49, a study from Brigham and Women's Hospital (BWH) finds that mammogram rates in the United States have not declined in that age group, or any other. The study results are published in the April 19, 2013 online edition of the journal Cancer. "If the USPSTF recommendations had been widely adopted, we would have expected to see a significant decline in mammography rates among women in their ...
