South America's vast pantanal wetland may become next everglades, UNU experts warn

...nal commodities ?mainly cattle and fishing ?cannot compete in today's marketplace," says UNU-PREP Director Dr. Teixeira. "Traditional farmers are selling their land to outsiders and large scale agriculture is taking place in the high-lands surrounding the Pantanal. In most cases, these newcomers do not know ...

Scientists solve structure of key protein in innate immune response

...LPS binding. Most, if not all, of the CD14 ligands compete with LPS for CD14 binding. Therefore, they probably share the same binding pocket with LPS." Ligands other than LPS can be accommodated in the pocket due to its large size, the flexibility of its rim, and the multiple grooves available for ligand bi...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...o molecular motors -- dynein and kinesin -- do not compete for control, even though they want to move the same cargo in opposite directions," said Paul Selvin, a professor of physics at the University of Illinois at Urbana-Champaign and corresponding author of a paper to appear in the journal Science, as par...

Two are better than one

...the antibodies were shown to cooperate rather than compete for distinctly different attachment points on the architecture of the receptors, resulting in the assembly of a large, springy molecular scaffolding between the receptor towers. The interlocking system grips and pulls the receptors towards each other...

Science study holds implications for gene therapy and stem cell biology

...larly how they grow and what factors cause them to compete with other stem cells or turn into more stem cells versus differentiating into different kinds of stem cells. "The next step would be to increase the availability of genes that enhance stem cell fitness using this novel approach. Simultaneously, we ...

Bacteria use host's immune response to their competitive advantage

...break through our immune defenses, they must first compete against other bacterial species to colonize the mucus-lined surfaces of our noses. Competition between two common nose bacteria involves some interesting trickery, according to a new study in PLoS Pathogens. "We're looking at how bacteria use their ...

Bacteria are key to 'green' plastics, drugs

...milar chemical reactions. That means the two don't compete or interfere with one another. In fact, Bennett and San designed the paths to be complimentary, but even so, they were gratified to see how well the process worked once both paths were put in place. "Our experiments in the laboratory have produced n...

Researchers create infectious hepatitis C virus in a test tube

They also showed that HepG2 cells, which do not express CD81 but can support HCV RNA replication, could not be infected by HCVcc unless they express CD81. Liver failure due to hepatiti...

Organic farms produce same yields as conventional farms

...onventionally produced crops. Organic farming can compete effectively in growing corn, soybeans, wheat, barley and other grains, Pimentel said, but it might not be as favorable for growing such crops as grapes, apples, cherries and potatoes, which have greater pest problems. ...

Researchers create functioning artificial proteins using nature's rules

Sugar helps control cell division

...as protein controllers, and it frequently seems to compete with phosphate groups for the same spots on proteins. Hart suggests that a particular balance between O-GlcNAc and phosphates on proteins may help fine-tune their activities. The researchers' next steps are to examine select proteins modified by O-G...
