We are family: the imperative for a chimpanzee genome project
...not get AIDS; instead, the virus lives in peaceful symbiosis
with the chimp immune system. Less commonly known is that chimps do not develop Alzheimer's disease, despite sharing a gene that is a high risk for Alzheimer's in humans. In addition, cancers such as breast, lung, and prostate tumors are apparently...
A harmonic 'Mnage trois'
...any, and their colleagues have discovered a unique symbiosis
between bacteria and a marine worm, described in Nature, issue May 17th 2001. The term symbiosis
typically evokes an image of beneficial interactions between two individuals, the symbiont and the h...
Important pathogens and cures belong to little-known group of fungi
...ier than previously thought. Therefore, the lichen symbiosis
has played a larger than expected role in the evolution of fungi. One of the consequences of this early origin is that several major lineages of non-lichenized Ascomycota species unexpectedly turn out to be derived from lichen-forming ancestors. The...
Drugs from sea study finds sponge health link to bacteria
...titute of Marine Science (AIMS). Understanding the symbiosis
of such microbes and sponges is a critical step in studying potential biologically active, possibly medicinal, compounds in such bacteria. Sponges are recognized as rich sources of new compounds with biologically active ingredients that could qualify...

Plant-fungal symbiosis found in high-heat extreme environment
...ssen Volcanic National Park have found evidence of symbiosis
between fungi and plants that may hold clues to how plants adapt to and tolerate extreme environments. The research was funded in part through the National Science Foundation's (NSF) Microbial Observatories Program and published in the Nov. 22 issue ...
Seaweed uses chemical warfare to fight microbes
...e antimicrobial compound could be the byproduct of symbiosis
between the seaweed and an as-yet unidentified microbe. If this is the case, it would be one of the rare examples of such a chemical defense for plants and animals, researchers reported. They believe that further investigations of chemically mediated...
Science historians ponder naming 'enemies' in science literature
