Largest study of human 'interactome' reveals a novel way

...s in yeast and 2,284 genes in mice whose effect on survival was known, according to Pandey. "Our much larger database on genes and proteins gave us the information to set the record straight on how to measure a protein's importance," he says. Using this kind of comprehensive comparison of information about ...

Wisconsin scientists discover a master key to microbes' pathogenic lifestyles

..." These changes, according to Klein, are really a survival program for the microbe, conferring resistance to the host's immune responses. The diseases caused by the fungi can be especially serious for immune compromised individuals, and some human populations seem to be more at risk for acquiring the infect...

Minimal genome should be twice the size, study shows

...emoves many of the genes that are essential to the survival of bacteria, according to researchers from Heidelberg (Germany), Manchester (UK), Budapest (Hungary) and Bath (UK). The researchers made this discovery after developing a new approach to genome modelling which, given the organism's evolutionary hist...

By comparing the long-term survival of breeders and non-breeders, Dammann and Burda found that the former lived extraordinarily long (up to 20 years) and on average about twice as long as their non-breeding counterparts. The researchers were also able to show that this pattern was not ...

Horseshoe crab decline threatens shorebird species

...he red knot's dependence on the horseshoe crab for survival has attracted the interest of local, state, and international wildlife management officials and researchers.
