Mystery of the Dying Bees Solved
jamie points out news of a study attempting to explain the decline of honeybee populations across the US. As it turns out, the fungus N. ceranae that was thought to be killing off bee colonies had a partner in crime — a DNA-based virus that worked in tandem with N. ceranae to compromise nutrition uptake. From the NY Times:
"Dr. Bromenshenk's team at the University of Montana and Montana State University in Bozeman, working with the Army's Edgewood Chemical Biological Center northeast of Baltimore, said in their jointly written paper that the virus-fungus one-two punch was found in every killed colony the group studied. Neither agent alone seems able to devastate; together, the research suggests, they are 100 percent fatal. 'It's chicken and egg in a sense — we don't know which came first,' Dr. Bromenshenk said of the virus-fungus combo — nor is it clear, he added, whether one malady weakens the bees enough to be finished off by the second, or whether they somehow compound the other's destructive power. 'They're co-factors, that's all we can say at the moment,' he said. 'They're both present in all these collapsed colonies.'"
RNA retroviruses, such as HIV.
Are bees an integral part of our society, and do they need to be present else we die off somehow.
If you'll excuse a slight over simplification: Yes.

For example, the flu is an RNA based virus... ;^)
Perhaps you might want to stick to writing computer programs
Somehow?
Do you eat any fruits or eat anything that ever ate a fruit? Including fruits that some people think are vegetables, tomatoes, peppers, cumcumbers, etc?
If so thank a bee. We do not have the man power to pollinate our crops by hand, without bees no fruit.
Bees are the primary pollinators in our world. Without them we'll have serious issues with plant growth and our food supply
Are bees an integral part of our society, and do they need to be present else we die off somehow....the impact of the species becoming extinct is not unimportant as let's say the platapus....I think if we can, we should help the species by giving them some sort of cure, if we can find it....else we might go without honey in our future.
Honey is just a nice side benefit - many many crops rely on bees to pollinate them. So much so that in the US, farmers pay people to drive hives around on trucks to pollinate their fields at the right time. Before this study, the stress of transport was thought to be connected to collapse disorder; it may still be a contributing cause.
As a practical beekeeper I feel it is my duty to take this one step further and speculate on how to apply this finding to saving my bees. Virus transmission should be kept to a minimum, I can't think of much else to do to keep a virus like this in check. The primary vector for honeybee viruses is the varroa mite and this pest continues to be the primary killer of honeybees despite all of the hubub about this "Colony Collapse Disorder". Finding that this mite has a hand in CCD is no surprise to me. Nosema is not new to the beekeeping world although N. ceranae is a bigger problem than the tamer N. apis that we're used to dealing with. The treatment is the same though, feed Fumidil B. The bad news is that there isn't much new here so there won't be a silver bullet cure. Keep the bees healthy as best we can, that's about all I can see here.
That farmers have to pay to have hives driven round because they liberally spray insecticides which wipe out local populations of native insects, including bees.

Bees are shipped all over the world, Australia and Israel are big bee colony producers.
The main reason that bacteria are easier to attack than fungi is that, since they are further down the evolutionary chain (they are prokaryotes, not eukaryotes like the fungi and humans), they are more likely to have proteins different enough from ours to serve as safe targets for drugs. Finding a protein that is foundamental for a fungi's survival yet different enough from the human counterpart is the main obstacle in developing effective antifungals.
The problem with viruses is that since they use the host's cellular machinary, they usually have a small amount of unique proteins, and thus exacerbating the problem mentioned above. BTW, an antiviral drug doesn't have to prompt the immune system's response (Interferon does that, but others, such oseltamivir, do not).
P.S. It's 2AM, I don't feel like including Wikipedia links. Feel free to look up what you need yourself. Sorry.
