Omega-3 fatty acids are unsaturated fats found in some fish such as salmon and herring and in smaller amounts in eggs and chicken.
New research from the Child & Family Research Institute shows the typical North American diet of eating lots of meat and not much fish is deficient in omega-3 fatty acids and this may pose a risk to infant neurological development.
This discovery is an important step towards developing dietary fat guidelines for pregnant and breastfeeding women. Current dietary recommendations evolved from the 1950’s emphasis on reducing saturated fat intake to lower the risk of cardiovascular disease.
U.S. Forest Service scientists believe an Oregon State University graduate student working on a cooperative project with the agency’s Pacific Southwest Research station on the Tahoe National Forest has photographed a wolverine, an animal whose presence has not been confirmed in California since the 1920s.
Katie Moriarty, a wildlife biology student, was conducting research on another carnivore called the American marten when a remote-controlled camera she set photographed the animal on February 28, 2008. Forest Service scientists who are experts at detecting rare carnivores believe the photographed animal is a wolverine.
The North American wolverine is the largest member of the weasel family. Adult males weigh 26 to 40 pounds, while females are 17 to 26 pounds.
In the latest issue of Nature Biotechnology, EuroStemCell scientist Elena Cattaneo from University of Milano along with Mauro Toselli from University of Pavia, Elisabetta Cerbai from the University of Florence and Ferdinando Rossi of University of Torino have challenged findings published in the same journal last year that amniotic fluid-derived stem cells can produce cells of the nervous system.
Amniotic fluid is the liquid that surrounds the fetus during pregnancy.
Scientists in Japan have discovered a new species of bacteria, Microbacterium hatanonis, that can live in hairspray, according to the results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology.
“Contamination of cosmetic products is rare but some products may be unable to suppress the growth of certain bacteria,” says Dr Bakir from the Japan Collection of Microorganisms, Saitama, Japan. “We discovered a new species of bacteria called Microbacterium hatanonis, which we found contaminates hairspray.
Growing concern over increased levels of atmospheric carbon dioxide has prompted new interest in techniques for removing the gas from the smokestacks of such large-scale sources as coal-fired electric power plants. But to minimize their economic impact, the cost of adding such controls must be minimized so they don’t raise the price of electricity significantly.
Researchers have developed a new, low-cost material called hyperbranched aluminosilica for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas.
Transfer RNA is an ancient molecule, central to every task a cell performs and thus essential to all life. A new study from the University of Illinois indicates that it is also a great historian, preserving some of the earliest and most profound events of the evolutionary past in its structure.
Of the thousands of RNAs so far identified, transfer RNA (tRNA) is the most direct intermediary between genes and proteins. Like many other RNAs (ribonucleic acids), tRNA aids in translating genes into the chains of amino acids that make up proteins. With the help of a highly targeted enzyme, each tRNA molecule recognizes and latches onto a specific amino acid, which it carries into the protein-building machinery.
