UMaine teams with fishermen to study affects of trawling on seafloor ecology

...had been made in the short term. "Scientists were predicting it would take decades for recovery, but didn't have an opportunity to look at it," said Knight. "This is the first project that has been able to look at areas closed for six years. We're already seeing signs of recovery after a significant amount of ...

Bacteria can help predict ocean change

... of species on land and sea, "we have some hope of predicting how changes are going to happen," Fuhrman said. ...

UCI scientists find chlorine may contribute to ozone formation

Standard methods of predicting air pollution don't take atmospheric chlorine into account, but the chemical could be responsible for 10 percent or more of daily ozone production in local air, research at UC Irvine has found. Air measurements taken nearly nonstop in the Irvine are...

AIDS vaccine research offers new insights on survival

...ction with an AIDS-like virus offer a new means of predicting an AIDS vaccine's effectiveness, a discovery that could help scientists as they test these vaccines in clinical trials. Led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and the Vaccine Research Center (VRC) at the National Institut...

New strategy developed to combat West Nile Virus

...for Disease Control. Many early hydrologic models predicting the transmission of West Nile Virus and other mosquito-borne diseases may have been a bit too simplistic, relying on factors such as total rainfall to estimate disease risk, said Jeffrey Shaman, an assistant professor of atmospheric sciences at Orego...

AIDS study challenges conventional treatment guidelines for HIV patients

...mount of HIV particles in the blood as a method of predicting a patient's ability to fight off the disease. The study, published in the current issue of JAMA (Journal of the American Medical Association), indicates that the amount of HIV in a patient's blood (commonly known as the viral load) is much less relia...

Better sludge through metagenomics

...h a view to understanding how the system works and predicting and averting failures or crashes. "This is a first step in a much broader strategy employing a systems biology approach to the study of microbial communities with the goal of designing predictive models to understand how these communities function,...

Circadian gene helps the brain predict mealtime

...ing the brain's cerebral clockwork responsible for predicting mealtime--with this tool in hand, it will be possible to anatomically localize areas of the brain that are involved in food anticipation. Looking forward, the researchers expect that this will allow the study of how these areas interact with other br...

Molecules in blood foretell development of preeclampsia

New way of tracking muscle damage from radiation

...nce imaging (MRI) could become a valuable tool for predicting the risk of muscle injury during and following radiation therapy, according to investigators at St. Jude Children's Research Hospital. The researchers report that MRI can spot the immediate injury done by radiation therapy to the muscles of childr...

Cryoablation -- A new treatment option for some kidney tumor patients

...the last 20 years, and the American Cancer Society predicting nearly 52,000 people will be diagnosed this year, with nearly 13,000 dying from it, another option for some patients is good news say the researchers. "Additional study is still necessary, but we are confident that percutaneous cryoablation will...

How to manage forests in hurricane impact zones

...een the most active on record, with climatologists predicting that heightened activity could continue for another 10 to 40 years. In early April, Colorado State University meteorologists predicted a very active 2007 hurricane season for the Atlantic coast, with 17 named storms, including 5 major hurricanes. The...

Bats prey on nocturnally migrating songbirds

...concentrations in bats' blood throughout the year, predicting major seasonal shifts in isotopic signatures towards bird prey in spring and, especially, during autumn. In parallel, isotopic signatures of whole insect bodies and passerine muscular tissues were tracked throughout the year, serving as a control. Th...

Climate change could trigger 'boom and bust' population cycles leading to extinction

...ity and specificity of the adrenal gland volume in predicting preterm birth within five days from the time of examination proves that 3-dimensional ultrasound evaluation of the fetal adrenal gland has the desired test characteristics to define a population at risk," they said. The current study creates the b...

Are one-third of costly implanted heart devices unnecessary? New study suggests yes

...ital and the OHVC, have studied the use of MTWA in predicting patients' risk for several years. Last spring, they published results from the same group of ischemic cardiomyopathy patients, showing that the MTWA test was able to predict the risk of death from any cause, even after they adjusted the data for ...
