July 3 (UPI) -- Norwegian oil company Statoil said Monday it was anticipating more potential near its promising Johan Castberg field after finding oil in a frontier area.The Norwegian Petroleum Directorate, the nation's energy regulator, confirmed the presence of oil in a well drilled about 14 miles southwest of the Johan Castberg field in the Barents Sea. The discovery was made in a wildcat well, one drilled in an area not previously known to hold hydrocarbons."We are particularly pleased to have proven resources in a type of play that has not been explored before," Jez Averty, senior vice president for regional exploration, said in a statement. "This opens interesting opportunities."The NPD put the preliminary size of the discovery, dubbed Kayak, at between 25 million and 50 million barr...

'Brain-eating' amoeba found in 2 water systems

Health
Brain-eating amoebas have been detected in two water systems in Louisiana, the state's health department said Thursday. Health officials reassured residents that drinking tap water is still safe and taking precautions in pools and showers can reduce their risk of infection. Health officials confirmed the presence of Naegleria fowleri, commonly known as the brain-eating amoeba, in Ouachita Parish’s North Monroe Water System and Terrebonne Parish’s Schriever Water System during routine water testing. The Louisiana Department of Health said it notified public health officials and the administrators of the water systems on Thursday afternoon. The health department urged residents to avoid getting water in their noses, which is how the organism can infect the brain. The department also advis...

June 12 (UPI) -- Why pass along the genes of a single mate when you can impart one's offspring with DNA from three fathers? Such is the unique reproductive strategy used by hybrid all-female populations of ambystomatid salamanders.When biologists from the University of Iowa sequenced the genome of all-female, or unisexual, salamanders, they found equal portions of DNA from three different species, Ambystoma laterale, Ambystoma texanum and Ambystoma tigrinum."We're hypothesizing the successful individuals have balanced gene expression," Maurine Neiman, a professor of biology at Iowa, said in a news release. "This balance might have been a prerequisite for the emergence and continued success of this particular hybrid lineage."Researchers believe all-female salamanders employ a reproductive t...
