Mystery of the Dying Bees Solved 347
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.'"

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.

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.

I assume you're joking, but just in case:
Honey is not the main thing we get from bees. The main thing we get from bees is pollination, and our food supply would suffer significantly if they were wiped out.

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.

Really all that needs to be developed is a weak fungicide that targets it, and that's not as hard as it sounds.
Actually, it is not that easy. Antibiotics (for bacteria) are easier to make than antifungals and that is one of the reasons why we don't have so many anti-fungal drugs for humans (and hu-womans).
Granted, when you develop a drug for bees you are less worried about side-effects than you are with humans, but it's still not that easy.

Bees aren't the only pollinating insects. Certain kinds of flies also do a decent job. Many plants are also self-pollinating, to one extent or another. And there's always the option of doing it manually.
That said, bees are extremely vital and their disappearance is cause for serious concern.

Brown is like its name, thick, earthy, think fresh turned earth, with sugar.
Green is as well, light, airy, with a sharpness - and there is the rub. Many do not like a sharpness in their sweet.

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.

I started this year and the time investment is very low once the colony is established. Most of the time they'll be happier if you just leave them alone.
