Study reveals new technique for fingerprinting environmental samples

...om the Pacific and Artic ocean depths separated by thousands of miles. The DNA was then sequenced and analyzed by the JGI. While different environments present different metabolic pictures, this research, Rubin said, facilitates a holistic perspective on environmental systems, something that many scientists wi...

Different microarray systems more alike than previously thought

...on of equipment that can analyze the expression of thousands of genes at once to create a genetic "fingerprint," suggests these different microarray technologies are more alike than once thought. Published in the May 2005 issue of Nature Methods, the study provides new hope that the mounds of information gene...

First technology to remove prions that cause vCJD from blood launched

...b (vCJD) prions may no longer be a concern for the thousands of people who require a transfusion. Pall Corporation (NYSE: PLL) announced today the Council of Europe (CE) marking of its Leukotrap® Affinity Prion Reduction Filter System. It is the first and only technology that removes infectious prions that may...

Cooperation is key—a new way of looking at MicroRNA and how it controls gene expression

... and society have been fascinated by those tens of thousands of stretches of DNA within the nuclei of cells we call our genes. One thing that has become clear in the last several decades, however, is that while our genes contribute to human health and disease, it is not always the genes themselves that matter...

New project aims to make large-scale lobster farms feasible

...rfarm, Inc., discovered that lobster larvae by the thousands happened to be settling on large submerged cages the company uses to raise fish. The cages, anchored in 100 feet of water, are about 50 feet high by 80 feet in diameter, making for a total of 12,000 square feet of lobster larvae-snagging surface area...

Migratory songbirds have a specialized night-vision brain area

...man Award to Jarvis. To migrate successfully over thousands of miles at night, night-migratory birds need to see where they fly, as well as navigate by stars and the earth's magnetic field. Surprisingly, Jarvis said, recent scientific evidence has suggested that birds have specialized molecules in their visua...

Doctors closer to using gene analysis to help trauma patients

...n St. Louis. Traumatic injuries claim hundreds of thousands of lives each year in the United States. In addition, millions of patients are hospitalized, at an annual cost to society of more than $200 billion. Patients may face a long and difficult recovery period riddled with many potentially fatal complicati...

To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter

There are chinook salmon populations in Idaho in which an occasional male stays put and matures when only 6 inches long ?that is, he's able to fertilize eggs at even that diminutive size, s...

South African Tribunal Asks For Damages Estimates in GSK AIDS Drug Case

UCLA scientists store materials in cells natural vaults

...d Geffen School of Medicine at UCLA have exploited thousands of tiny capsules in cells to store vast amounts of biomaterial. Dubbed vaults ?for their high arches reminiscent of cathedral ceilings ?these naturally occurring capsules may prove less likely to elicit an immune response than foreign carriers like v...

Findings have implications for tracking disease, drugs at the molecular level

...cles under conditions where people usually look at thousands or millions of stain molecules. This could allow us, for instance, to track a single molecule of a drug in a cell or other biological sample." Other advantages of the technique are that the gold particles can be prepared easily, have very low toxici...

The biggest family tree ever

...ravel the origins and migratory history of mankind thousands of years back in time by analyzing genetic samples from at least 200,000 people all over the world. National Geographic and IBM are embarking on the Genographic Project, a landmark, five-year global study of human migratory history. The project will...

Designing vaccines by computer
