Premature births may be linked to seasonal levels of pesticides and nitrates in surface water

...d States as a whole during April through July, the same months as pesticides and nitrates reach their maximum concentrations in surface water. This year's presentation expands upon that work. "A growing body of evidence suggests that the consequence of prenatal exposure to pesticides and nitrates as ...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...ousands of genes for variations. Everyone has the same genes, but variations in them influence whether or not a person gets a specific disease. In this study, researchers compared variations found in the scans of 413 adults who had bipolar disorder with variations found in the scans of 563 healthy adult...

Scientists develope a new model of artificial canine skin

High-dose anticlotting drug cuts heart attack, death risk in half

...5 and p=0.98, respectively). Findings remained the same when the analysis was restricted to 7 randomized controlled trials only. Further analysis showed that the higher the underlying risk of complications related to blood clotting, the greater the benefit from high-dose clopidogrel. The study will be...

Magnetic computer sensors may help study biomolecules

...the electron "spins" in the magnetic layers in the same (on) or opposite (off) directions. NIST researchers made an array of spin valves, each about one by four micrometers in size, patterned on a 200-nanometer-thick silicon nitride membrane in fluid. When the spin valves are turned on, a local magnetic f...

Researchers attach genes to minichromosomes in maize

...inichromosomes are able to function in many of the same ways as chromosomes but allow for genes to be stacked on them. Although other forms of genetic modification in plants are currently utilized, the new minichromosomes are particularly useful because they allow scientists to add numerous genes onto one...

Gene thought to assist chemo may help cancer thrive

...as the gene p53. While both groups had roughly the same amount of the protein encoded by p53, the cancer group had mutations in their p53 that caused the gene’s corresponding protein not to function.The benign group's p53 was normal. Five years later, only 30 percent of the chemotherapy cancer patients...
