Patients already taking warfarin who develop an acute stroke appear more likely to experience a brain hemorrhage following treatment with an intravenous clot-dissolving medication, even if their blood clotting function appears normal, according to a new study. - [Read more]

Social insects -- ants in particular -- are usually thought of as selfless entities willing to sacrifice everything for their comrades. However, new research suggests that ant queens are also prepared to compromise the welfare of the entire colony in order to retain the throne. - [Read more]

Bad behavior in childhood is associated with long-term, chronic widespread pain in adult life, according to the findings of a study following nearly 20,000 people from birth in 1958 to the present day. The research found that children with severe behavior disturbances had approximately double the risk of chronic widespread pain by the time they reached the age of 45 than children who did not have behavior problems. - [Read more]

Governor Sonny Perdues water conservation bill is one step closer to becoming law after the Senate approved the proposal, which is also up for consideration in the House.

A new assay allows scientists to discover whether ticks are carrying disease-causing bacteria and which animals provided their last blood meal. Assay results suggest three emerging diseases in the St. Louis area are carried by lone star ticks feeding on record-high populations of white tailed deer. - [Read more]

Pharmaceutical companies could substantially reduce the expense of costly treatments for cancer and other diseases produced from mammalian or bacterial cells by growing these human therapeutic proteins in algae -- rapidly growing aquatic plant cells that have recently gained attention for their ability to produce biofuels. - [Read more]

Most people are familiar with security technology that scans a persons handprint or eye for identification purposes. Now we are closer to practical technology that can test someones voice to confirm their identity. - [Read more]

In one of the first such studies involving human patients with schizophrenia, researchers have provided evidence that deficits in a brain chemical may be responsible for some of the debilitating cognitive deficits -- poor attention, memory and problem-solving abilities -- that accompany the delusions and hallucinations that are the hallmarks of the disorder. - [Read more]

Tornadoes have struck parts of Arkansas, injuring four people and destroying a handful of homes.

A study shows that frequent napping is associated with an elevated prevalence of type 2 diabetes and impaired fasting glucose in an older Chinese population. - [Read more]

A three-year field program now underway is measuring carbon distributions and primary productivity in the Northwest Atlantic Ocean to help scientists worldwide determine the impacts of a changing climate on ocean biology and biogeochemistry. - [Read more]

Visitors to national parks and forests are encouraged to use bear spray when they encounter grizzlies, but disposing of the bear spray canisters is a problem that students have addressed. - [Read more]

An expert calls for change in the way researchers and pharmaceutical companies collect and report adverse symptom information in clinical trials submitted to the Food and Drug Administration, and how the FDA represents this information on drug labels. - [Read more]

Flooding in Mozambique killed two people and displaced hundreds of families, prompting the government to step up rescue operations and issue a red alert for some areas.

Leaked e-mails, punctured arguments lead to closer scrutiny of climate science.

Sonic hedgehog is at work in mice limb buds in what is known as the ectoderm, the cell layer that gives rise to skin, researchers discovered. Finding Sonic hedgehog here is akin to discovering that yeast has crept from the batter to the frosting, where it has the surprising effect of limiting how much the cake rises. In this case, instead of causing appendages to grow in mice, Sonic hedgehog prevents digits from developing. - [Read more]

Share + Mar 10, 2010 3:32 pm US/Eastern NEW YORK In the coming months were going to by paying for our unusually cold South Florida winter every time we pick up orange juice at the store.

While general relativity describes well the behavior of the solar system, Einsteins theory of gravity and spacetime has not been tested on cosmological scales. Now, a team has analyzed data on 70,000 galaxies to show that the theory is so far the best description of the universe, at least out to 3.5 billion light years from Earth. Specifically, theories without dark matter do not fit the observations. - [Read more]

A newly discovered ability for people to taste fat could hold the key to reducing obesity, researchers believe. They also found that people with a high sensitivity to the taste of fat tended to eat less fatty foods and were less likely to be overweight - [Read more]

Rivers are rising across Iowa as snow melts and rains are forecast in the state.

A new study finds that obese children as young as 3 years old have elevated levels of C-reactive protein, a marker of inflammation that in adults is considered an early warning sign for possible future heart disease. - [Read more]

Older men with high levels of the hormone IGF-I (insulin-like growth factor 1) are at increased risk of cancer death, independent of age, lifestyle and cancer history, according to a new study. - [Read more]

Papaya extract seems to have a toxic effect on cancer cells in culture, suggesting a potential treatment. Scientists documented for the first time that papaya leaf extract boosts the production of key signaling molecules called Th1-type cytokines. This regulation of the immune system, in addition to papayas direct anti-tumor effect on various cancers, suggests possible therapeutic strategies that use the immune system to fight cancers. - [Read more]

A researcher believes pottery found throughout the North American Southwest comes from a religion of peace-seeking women in the violent, 13th-century American Southwest. These women sought to find a way to integrate newly immigrating refugees and prevent the spread of warfare that decimated communities to the north. - [Read more]

The experimental drug belatacept can prevent graft rejection in kidney transplant recipients while better preserving kidney function when compared with standard immunosuppressive drugs, data from two international phase III clinical trials show. - [Read more]

Researchers in Austria are investigating the effects of the Earths atmosphere on our planets shape, its rotation and its gravitational field. The researchers aim is to develop a better understanding of the Earths system and to support the development of the Global Geodetic Observing System (GGOS). - [Read more]

Measurements of hemoglobin A1c (HbA1c) more accurately identify persons at risk for clinical outcomes than the commonly used measurement of fasting glucose, according to a new study. HbA1c levels accurately predict future diabetes, and they better predict stroke, heart disease and all-cause mortality as well. - [Read more]

Removal of the ovaries (bilateral oophorectomy) while performing a hysterectomy is common practice to prevent the subsequent development of ovarian cancer. This prophylactic procedure is performed in 55% of all U.S. women having a hysterectomy, or approximately 300,000 times each year. A new article suggests that this procedure may do more harm than good. - [Read more]

Scientists have found evidence of a catastrophic event they believe was responsible for halting the birth of stars in a galaxy in the early universe. The researchers observed the massive galaxy as it would have appeared just three billion years after the Big Bang when the Universe was a quarter of its present age. - [Read more]
