We've all heard that eating fish is good for our brains and memory. But what is it about DHA, an omega-3 fatty acid found in fish, that makes our memory sharper? Medical researchers at the University of Alberta discovered a possible explanation and just published their findings in the peer-reviewed journal Applied Physiology, Nutrition, and Metabolism. Principal investigator Yves Sauve and his team discovered lab models fed a high-DHA diet had 30 per cent higher levels of DHA in the...

Buttery shrimp. Fried eggs. Burgers and fries. New research suggests there may be a biological reason why fatty and cholesterol-rich foods are so appealing together. It has been known for more than 40 years that dietary fat promotes cholesterol uptake, but fundamental aspects of that process remain poorly understood. James Walters, Ph.D., and his colleagues at the Carnegie Institution for Science are using zebrafish to better understand the cellular mechanisms of cholesterol processing and...

Ursolic acid -- a waxy substance found in apple peel -- increases muscle and brown fat in mice on a high-fat diet: These mice burn more calories and have reduced obesity, pre-diabetes and fatty liver disease than mice not receiving the supplement Obesity and its associated problems such as diabetes and fatty liver disease are increasingly common global health concerns. A new study by University of Iowa researchers shows that a natural substance found in apple peel can partially protect...

Findings suggest ways to increase oil production for biofuels and industrial processes Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have identified key elements in the biochemical mechanism plants use to limit the production of fatty acids. The results suggest ways scientists might target those biochemical pathways to increase the production of plant oils as a renewable resource for biofuels and industrial processes. "Now that we understand how this...

Single cell oils (SCO), produced by and extracted from some single-celled microorganisms, are featured with high levels of the major very long chain polyunsaturated fatty acids (PUFA). SCO are essential for health and potential sources of bio-diesel. There has been a long history of interest in the exploitation of microorganisms as oil and fat providers, due to the continuing diminution of arable land and climate change making animal and plant sourced oils even more limited. However, such...

Scientists are reporting development of a healthy "designer fat" that, when added to infant formula, provides a key nutrient that premature babies need in high quantities, but isn't available in large enough amounts in their mothers' milk. The new nutrient, based on hazelnut oil, also could boost nutrition for babies who are bottle-fed for other reasons. Casimir Akoh and colleagues explain that human milk is the "gold standard" for designing infant formulas. Mothers naturally provide the...

For the first time, researchers at the University of California, San Diego have peered inside a living mouse cell and mapped the processes that power the celebrated health benefits of omega-3 fatty acids. More profoundly, they say their findings suggest it may be possible to manipulate these processes to short-circuit inflammation before it begins, or at least help to resolve inflammation before it becomes detrimental. The work is published in the May 14, 2012 online Early Edition of the...

Chalcone-isomerase protein holds much promise of economic benefit A curious twist in a family of plant proteins called chalcone- isomerase recently was discovered by Salk Institute for Biological Studies scientist Joseph Noel and colleagues at Iowa State University led by Eve Wurtele. Pursuing basic scientific discovery, they found three similar proteins that could soon translate into positive results for bio-renewable fuels, commodity chemicals like plastics, food security and...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
