Forgetful Casanovas are lucky in love. At least that's how University of Florida researchers interpret the results of new research on the mating habits and nervous systems of prairie voles.
A new study found that taking two NSAIDs was associated with lower scores on a health-related quality of life assessment. Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat arthritis, which affects one-third of all adults. These drugs are available in both prescription and over-the-counter forms and are one of the most commonly prescribed medications in the world. Because of their widespread availability, patients may take both forms at the same time, either because of inadequate pain relief or because they are unaware that they are taking two drugs in the same therapeutic class.
Ice caps on the northern plateau of Baffin Island in the Canadian Arctic have shrunk by more than 50 percent in the last half century as a result of warming, and are expected to disappear by the middle of the century. Researchers also find tantalizing evidence that ancient tropical eruptions of volcanoes triggered Little Ice Age.
A new study of age-related macular degeneration, the disease that affects more than nine million Americans, will pave the way for the biopharmaceutical industry to develop better treatments and cures.
The combined supercomputing power of the UK and US 'national grids' has enabled scientists to simulate the efficacy of an HIV drug in blocking a key protein used by the lethal virus. The method -- an early example of the Virtual Physiological Human in action -- could one day be used to tailor personal drug treatments, for example for HIV patients developing resistance to their drugs.
The terrorist attacks of Sept. 11, 2001, changed our lives in a number of different ways, not only socially and politically, but also in the way in which we dream. According to the results, dreams after 9/11 showed more intense images, but were not longer, more dreamlike or more bizarre. In addition, they did not contain more images of airplanes or tall buildings. In fact, not a single dream involved planes flying into towers, or anything close to that, even though all participants had seen those images many times on TV.
Splash! Ooch! Yum! And so another unsuspecting insect victim of Nepenthes alata (N. alata), commonly known as the carnivorous pitcher plant, falls victim to the digestive fluids at the bottom of the plant's famous cup-shaped leaf.
Smokers have a two-fold increased risk of developing colorectal polyps, the suspected underlying cause of most colorectal cancers, according to a new study.
Revolutionary technology aims to 'make safety a sure thing.' Aircraft, cars, medical equipment and industrial robots are all examples of modern systems which contain safety-related processors. New technology makes it easier to develop systems with predictable behavior - a key requirement for safe systems.
A treatment commonly given for anemia, promotes blood-vessel growth in the eye, an effect that could either improve/worsen disease for patients with cancer, diabetic retinopathy, or retinopathy of prematurity. The effects on retinopathy depend on the timing of when the erythropoietin treatment is given.
While biomedical, electronics, and other branches of research are marching steadily into the realm of the smaller-than-small nanometer scale, building needed materials at this scale has been problematic. Recently, however, a team from The Scripps Research Institute unveiled a novel approach to the problem that yields a material with novel properties, which some might find reminiscent of Flubber. The material is produced using naturally occurring proteins as templates for uniform, self-assembled, nano-scale construction.
Youths with insomnia, particularly chronic insomnia, are at greater risk of future somatic and especially psychological problems, according to one of the largest epidemiologic studies of insomnia among adolescents ever conducted in the United States.
First results from a new scientific instrument at the W. M. Keck Observatory in Hawaii are helping scientists overturn long-standing assumptions about powerful explosions called novae and have produced the first unified model for a nearby nova called RS Ophiuchi.
High levels of the Ki-67 protein are associated with poor prognosis in early breast cancer patients, but it may not able to predict which patients will benefit from additional chemotherapy. The percentage of proliferating cells in a tumor is a predictor of breast cancer prognosis. The level of Ki-67 expression is sometimes used as a measure of cell proliferation. Some studies have suggested that breast tumors with a high percentage of cells expressing Ki-67 are more responsive to chemotherapy.
