Really? A single bee. What does that tell anyone?

http://evolution.anthro.univie.ac.at/institutes/urbanethology/resources/articles/articles/publications/NEL230202R03scent.pdf Interesting question. I would say yes they probably can smell fear but do you see them targeting newcomers standing beside a hive or the person presenting the biggest...

To adjust the z height I am using a motorised stage. Its a 3/4 million pound scope!

Hi Itma, No to both questions. In the confocal microscope out of focus light is blocked with a pinhole. I set the z dimensions and how many steps or focus planes and how thick they should be, then it acquires all the slices. In Image J I deconvolved the stack to increase the resolution. All the...

Hi all, Just for your interest, this is a confocal stack of some pollen grains found in my honey. The stack has been average projected to form the 2D image after deconvolution in Image J. The pollen was then artificially coloured using Photoshop. LC

Thanks for the replies everyone. The problem really is when using the valve to fill jars no matter how well tightened the screws are the action of sliding it up to let honey out eventually moves honey around the opening. After enough jars it gets messy and although backward pressure helps as...

Hi all, I have had enough of the standard honey bucket gate valves (they leak all around the opening when using) and would like to put a lever style metal one in for next year. Would any type of gate valve made with stainless steel grade 304 be acceptable? Anybody already done this?

Is it that you want to clean the slides to look at the specimens that are on them already? A wipe with some alcohol will remove oil etc. If it is to recycle the slides (permanent mounts) please don't bother. I'd rather dry and reuse teabags.

Not sure if that is allowed, the problem I can see is how do you get all the info required at the right sizes on a lid?

Some bad and some terrible jokes guys! Thinking sideways, there could be something in this for the pollination crowd. If you started the bees off with a bit of caffeinated syrup they might concentrate their efforts to that locality?

And yes you can get mounts to reduce magnification.

Hey, To work out magnification you measure the size you see on the screen. On my screen your third image is about 190 mm. Based on Ruary's figure quoted as 0.102 mm for a crocus pollen this would leave your magnification at 190/0.102 = 1863x And the oil is from the pollen as you were told. LC

Just to add the equation: field size = field number on lens / magnification - as alanf pointed out this should be checked when you go looking for a stereomicroscope. (This is of course different from depth of field which typically decreases with higher magnification as well).

The stereo effect comes from not only twin lenses but the way the images are inclined by a few degrees. I would also point out, perhaps wrongly, that Baggyone did not say it was suitable for dissection. Maybe a picture or two of pollens from one of these Lidl things might be useful here?

The fact remains that you can't use high magnification to view dissection, so its not a red herring.. Horses for courses I agree with

What makes a digital microscope a compound microscope? It could have one lens and the image projected onto a CCD, this isn't a compound microscope. The reason why the digital microscope might not be suitable for dissection is that the magnification is typically too high compared to a...
