Breakthrough developments in rheumatoid arthritis reported

...at leads to painful joint swelling. Scientists are cracking the genetic code that makes the immune system wage an attack on a person’s joints. Over the last decade, Dr. Gregersen and his colleagues have been amassing a genetic database complete with siblings with rheumatoid arthritis (and some family members ...

The chimpanzee stone age

Even a little cooling helps after cardiac arrest

... healthy? To answer this, Sea Grant biologists are cracking open common marsh snails and counting parasitic worms. Their claim: the more parasites, the healthier the marsh. While the parasite hypothesis may conflict with conventional ideas about infectious disease and human health (malaria, for example, is c...

How healthy is that marsh? Biologists count parasites

Scientists discover a genetic code for organizing DNA within the nucleus

...eagues from Northwestern University in Chicago, in cracking the genetic code that sets the rules for where on the DNA strand the nucleosomes will be situated. Their findings appeared today in Nature. The precise location of the nucleosomes along the DNA is known to play an important role in the cell's day ...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...anostructure to serve as a reservoir for water, no cracking or shrinkage is observed. The cells are maintained in the necessary fluidic environment." The cell-architected nanostructure is, he says, "an amazing way to preserve a cell." The cells already have emerged still viable after examination in electr...

Cracking the genetic code for control of gene expression

...elsinki, Finland, came together to advance towards cracking the code for how gene expression is controlled. The results of this work are published in Cell, in January 2006. A genome milestone was reached in 2001 when sequencing of the human genome was completed. This has been followed by complete chemical re...

Carnegie Mellon scientists show brain uses optimal code for sound

...scientists traipsed through the woods and recorded cracking branches, crunching leaves and wind rustling through leaves before returning to the laboratory to de-code the information contained in this rich set of sounds. They also discovered what they consider the most "natural" sound: if they play back a rand...
