Bee Disease Still A Mystery, Despite New Advances In Undersanding Common Virus




Scientists are one step closer to understanding the recent demise of billions of honey bees after making an important discovery about the transmission of a common bee virus. Deformed wing virus is passed between adult bees and to their developing brood by a parasitic mite called Varroa destructor when it feeds. However, new research suggests that the virus does not replicate in Varroa, highlighting the need for further investigation.

Rubber 'Snake' Could Help Wave Power Get A Bite Of The Energy Market
A device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves. Named after the snake of the same name because of its long thin shape, the Anaconda is closed at both ends and filled completely with water. It is designed to be anchored just below the sea's surface, with one end facing the oncoming waves.

Development Of Laser Spectrometer Opens The Way For More Effective Carbon Trading, Drug Development And Carbon Dating
Carbon offsets increasingly are becoming a major component in the arsenal for reducing global warming. Even Bon Jovi, the Rolling Stones and the Dave Matthews Band are doing it: acquiring carbon offsets to reduce the carbon footprint of their tours. As more organizations and businesses start trading in carbon offsets, the need for accurate measurements of carbon emissions also is becoming critically important for fair and exact exchanges.

where to get helium
me and my friend are making a very large blimp and were wondering what we should do for gas

going to a store to get it filled up is out of the question simply because it will be much too large. not only that we still need to do things like balance it and test its flight out and everything. we're using garbage bags as the membrane and trying to keep it as simple as possible to avoid small leaks but they cant be stopped without adding a lot of tape.

so i was wondering a few things

helium or hydrogen

hydrogen would be a lot cheaper and would end up having a lot more lift which we need all the lift we can get because we live at 6500 ft
but its also explosive, and hard to find. i have no idea where i would find hydrogen and whether or not most companies would even sell to an individual.

helium is very stable but has the worse part of the items mentioned before cost and lift.
although it is way easier to get helium apparently you can go to almost any party store and just pick a tank up for like $20

would another gas be suitable?

any help would be greatly appreciated
in fact if you do contribute significant help we would be willing to put a "sponsored by" on the side of the blimp
