- Bugscope TeamWe are pumping down.
- Bugscope Team1.8 x 10-4
- Bugscope Team1.7
- Bugscope Team1.6
- 3:35 pm
- Bugscope Team1.5
- Bugscope Team1.4
- Bugscope Teamalmost there
- 3:42 pm
- Bugscope Teamhey tony, welcome back
- Bugscope TeamTony we are setting up.
- Bugscope Teammaking the presets for your session. Cool?
- 3:53 pm
- 3:58 pm
- 4:04 pm
- 4:10 pm
- Bugscope TeamAlright that is it. You are the supreme ruler, Dr C.
- Bugscope Teamhi leticia
- Bugscope TeamHi Leticia! Are you with Dr Clishem?
- Bugscope Teamwe are ready anytime tony
- Bugscope Teamor are you from the Outer World somewhere?
- Bugscope Teamhi chad, welcome to bugscope
- Studenthello alex... this is great
- Bugscope TeamHello!
- Bugscope TeamWhere are you?
- 4:16 pm
- Bugscope TeamOh cool.
- GuestThank you for sharing your technology with us today!
- Bugscope Teamno prolemo
- Bugscope Teamyeah no problemo
- Bugscope Teamthe fruit fly's eye is a little desiccated
- Bugscope Teamyou can still see its antennae
- Bugscope Teamgo ahead and ask us any questions you may have
- Bugscope Teamand a minute ago we could see brochosomes, from a leafhopper, on the surface of the compound eye.
- Guestwhat are the little parts that look like rice?
- Studentwhat are the rice looking things on the eye
Bugscope Teamthose are called setae (pronounced see-tee)
- Bugscope Teamsetae help insects to sense their environment
- Studentwhat do the see tee do
- Bugscope Teamsetae can be mechanosensory or chemosensory, among other things
- 4:21 pm
- Bugscope Teamthese setae are thought to hep the fly sense wind movement while flying
- Studenthow do they sense their environment
- Bugscope Teambut some setae near the mouth might sense chemicals, for tasting and smelling
- Bugscope Teamwell, since insects have a hard exoskeleton, which can't feel anything, the setae stick through that and connect to nerves underneath
- Studentwhy do they have ridges
- Bugscope Teamand the setae sense temp, chemicals, movement, etc. and transmit that info to the nerves
- Bugscope Teamthe compound eye is made up of thousands of individual facets, each with a lens in it, the facet is called an ommatidium
- Studentthis is really coollll
- Studentnice whats the white flacks around the setae
Bugscope Teamwell, i'm not sure what that big white blob is, probably juju
- Studenthead and shoulders
- Bugscope Teamjuju = not part of the bug or any symbiotic organism
- Bugscope Teamright, dandruff could be juju, although it does come from us, so maybe not :)
- Bugscope Teaminsects have TONS of setae, all over
- Guestwhy is the wing lined with spikes?
- Bugscope Teamthey must have setae, or else they wouldn't feel anything
- Studentwhat do the hairs do on the wings
- Bugscope Teamthose spikes are setae again
- Bugscope Teamthe setae help the insects to know what's going on around it in its environment
- Bugscope Teamsensory feedback
- Bugscope Teamthese setae are probably mechanosensory, they feel wind movements, and aid in the flight of the insect
- Studentwhy do they differ in shape than the ones on the eye
Bugscope Teamgood questions. i'm not 100% sure, but different needs develop different setae
- 4:26 pm
- Studentdifferent nerves?
Bugscope Teamhmm, good question, but i'm not sure about the nerves under the exoskeleton, but yeah, probably the nerve is different so that it can sense different inputs
- Studentthank you
- Bugscope Teamwe aren't sure exactly what this is, but it is an aquatic insect and it kinda looks like a roly poly
- Studentdo all bugs have setae
Bugscope Teamwell, i think all, yes, but i could be wrong
- TeacherCould we now open up the controls to the students?
Bugscope Teamyes, just let us know who wants control
Bugscope Teamjust let us know who you would want to have control
- TeacherCindy will now take control
- Bugscope Teamcindy has control now
- Studentwhat is the smallest part of exoskeleton and what are those bumps on the claw
- 4:31 pm
- Bugscope Teamthe claw here has some juju stuck to it. looks like some plant material and some other stuff
- Guestwhat is the smallest part of exoskeleton
Bugscope Teamhmm, well, the exoskeleton covers the entire insect, so i'm not sure what the smallest part would be...
- Guestwhat would be interesting to look at on this specimen?
Bugscope Teamthe scope can magnify many times over, and there is detail of great interest if you zoom up, give it a try
- Studentwhat end are we looking at
- Bugscope Teamthis is one of those insects that rolls into a ball when you disturb it
- TeacherCould you please let Wafa take over the controls?
Bugscope Teamwafa has control
- Bugscope Teamwafa has control
- Bugscope Teamthere are spiracles (breathing holes), palps, mandibles, bacteria, compound eyes, crochets, prolegs, etc. etc. etc.
- Bugscope Teamalso, look at the different presets, you can click on any preset and it'll move you to that location
- Studentis this the head of the bug
Bugscope Teamyep the head is small, but it's near the top
- Bugscope Teamwaya, you have control
- Teacherwafa's controls are sort of frozen
- 4:36 pm
- Bugscope Teamwafa, i mean, sorry
- Bugscope Teamhmm, wafa, try refresh F5
- Bugscope Teammaybe the network is having problems, we are seeing wafa go in and out of connection
- Bugscope Teamare you all on a wired network, or wireless?
- Bugscope Teamokay tony, you have control again
- TeacherWe are wired.
- Bugscope Teamare you able to control tony?
- Bugscope Teamif not, let me know
- Bugscope Teamtry clicking on a preset
- Studentwhat are the two things surrounding the mouth
Bugscope Teamthose are mandibles, they help it to shove food into it's mouth, or cut up food
- TeacherIt's thinking.
- Bugscope Teamhmm, something must be wrong, hold on
- Studentthank you
- Guestwho uses bugscope te most elementary, highschool or universities
Bugscope Teamit is K through 12, although sometimes we have teachers and/or college students
- Studentmore juju
- Bugscope Teamwait, those are palps i think not mandibles
- Bugscope Teampalps help taste the food, or smell it
- Bugscope Teamokay, i think i fixed the scope, tony give it a try again, i'm unlocking now
- Studentthats crazy
- TeacherShould I try to control now?
Bugscope Teamyep, give it a try
- 4:41 pm
- Bugscope Teamyay!
- Bugscope Teamchas conway built the entire 2.0 website, it is much better than 1.0
- Bugscope Teamscott robinson has been with bugscope since 1998
- Bugscope Teamscott is one of the original developers
- Guestthe whole thing is quite impressive!!
Bugscope Teamyeah, when chas built this website, i was like, dude, you RULE!!!
- Bugscope Teamcate and i came on later. cate is an electron microscopist. i'm a sysadmin
- GuestI agree!!
- GuestCan we use this from home, too?
Bugscope Teamanyone in the world can login to a session live, as guest...
- Bugscope Teamscott is also an electron microscopist, and he's also manager of this microscopy suite lab
- TeacherLet wafa try again.
- Bugscope Teamall you need to run bugscope is a browser
- Studentmore and different setae?
Bugscope Teamthese look like mechanosensory setae again, sensing wind
- Guestthat is cool are class is going to teach were in education
- Studenthow much does this bug weigh
Bugscope Teami have no idea!!! but good question. i wonder if it's possible to build a scale in the scope.. probably not because the sample needs top be absolutely still
- Bugscope Teamwe try to chat in a way the kids will enjoy it. we are not stiff science geeks. well we may be that, but we try to make science fun for the kids.
- Studenthow does the juju stick to the body
Bugscope Teamwell, dust collects on anything, but before the bug goes into the scope, we coat it with gold-palladium, which helps the electrons bounce off the sample
- 4:46 pm
- Bugscope Teamso the dust gets trapped inside the gold-palladium
- TeacherPlease give Magdasz the controls
- Studentgold palladium please explain what palladium mean
Bugscope Teamit is a metal compound that is very thinly coated onto the sample. this is required for any electron microscope, otherwise the sample would charge up and you wouldn't get any image at all
- Bugscope Teambut some juju is cool to look at, like pollen, bacteria, brochosomes, etc.
- Studenthow much gold is needed to coat a fly
Bugscope Teamvery little, there is a special machine that breaks up the gold-palladium into a very fine dust that settles onto the sample
- GuestI don't see the presets
- Studentthank you guys
- Studenton the eye
- Bugscope Teameach facet of the compound eye has a lens in it
- Studentwhat is the name of the long thing by the eyes on the head
Bugscope Teamwell, the thing coming out of the middle of the head is the proboscis
- Bugscope Teamand the lens is fixed, unlike human eyes that can move the lens around
- Bugscope Teamthe long thing coming out the side, that was an antenna
- 4:51 pm
- Bugscope Teamthe proboscis curves up, like a party favor
- Studentnice info
- Bugscope Teambut this is the proboscis that the fly uses to feed. it pukes on it's dinner, then sucks up the puke and food with the proboscis... yum!!!!
- Bugscope Teamfocusing can be hard
- Studentdoes it act as a tongue
Bugscope Teamwell, i don't think so, the palps would be more like a tongue. but if the proboscis had setae on it (not sure if it does) then those setae would probably taste/smell things...
- Bugscope Teamtry one way, if it gets worse, go another way
- Bugscope Teamnice!!!!
- Guestwhat were the black spots
Bugscope Teamnot sure, what black spots?
- Studentdoes the puke dissolve the food
- Guestwhy does it need to vomit to eat its food?
Bugscope Teamit can only digest liquids, so it's vomit turns hard food into a liquid and thus is can eat it
- Bugscope Teamthe puke works like our saliva to break down the food
- Studentdo you have any spides
- GuestI think they were on the leg...
- Guestew thanks
- Studenti bet
- Guestwhat is that
- Guestwhat are we looking at?
- Bugscope Teamtry clicking on the scale bar in the lower left, it'll tell you
- Bugscope Teamwell, it'll tell you what preset we are on
- TeacherWe are going to drive around for about 15 more minutes
- Bugscope Teambut as to what this is specifically, i'm not sure, if you zoom out i can tell you
- Guestits the eye?
Bugscope Teamwell, no, this is a part in front of the eye i think? try zooming out
- 4:56 pm
- Bugscope Teamand try focusing too... let me know if you need help
- TeacherGive Tony (Dr. C) the controls.
- Bugscope Teamfocus can be tricky to control
- Guestso what does it do?
Bugscope Teamwhat does focus do? is changes the magnification very slightly
- Bugscope Teami would generally stay away from focus unless you aboslutely need it
- Guestno not that
- Bugscope Teamstill not sure what this is?
- Guestthe part thats in front of the eye
Bugscope Teamthe curved thing? that's the proboscis
- Guestwhat is the farthest school that has participated on bugscope??
Bugscope Teamchina, japan...
- Bugscope Teamthis is a small moth
- Studentcan we look at the spiracle breathing hole
Bugscope Teamsure, ask tony to click on preset #7
- Bugscope Teamoops, sorry, had it locked, just unlocked it
- Bugscope Teamtry preset #7 tony
- Bugscope Teamthis is a spiracle
- TeacherWhat's a true bug
Bugscope Teamit is an order of species that comprises about 80,000 different insects
- Bugscope Teamthis is how bugs breathe
- Teachergive chad controls
- Studentcan we rotate 90 degrees
Bugscope Teamwell, you can sometimes do things like that with an ESEM, but it's complicated, and for bugscope we don't do that.... sorry
- GuestWhat is coming out of the hole?
Bugscope Teamsometimes spiracles will have setae or some kind of chitin that helps to block stuff from falling into it
- 5:02 pm
- Studentits cool
- Studentwhat if juju becomes stuck in the hole
Bugscope Teamgood question, it has like nose hairs, or setae hairs
- Studentwhat is chitin
Bugscope Teamchitin is like your finger nails, the exoskeleton is made up of chitin
- Studenti am i buggin you guys with all the questions
Bugscope Teamheh, buggin is cool when in bugscope
- Bugscope Teamwow cool! that pattern looks like the inside of the exoskeleton, i'm not sure i've seen that before. VERY COOL!
- Bugscope Teamyeah, that pattern is on the inside of the exoskeleton. good job tony, you are doing great.
- Bugscope Teamcheck out the scale bar lower left
- Bugscope Team5 um is 5 microns
- Bugscope Teamone micron = one millionth of a meter
- Bugscope Teammicrons are micrometers
- TeacherWhat should we absolutely look at before we quit?
Bugscope Teamtry preset #1, it's a pollen grain
- Bugscope Teamnice
- Bugscope Teamthat ball with spikes, that's a pollen grain
- Bugscope Teamwe often find pollen grains on insects
- Bugscope Teamthe spikes make it easy for it to get caught in stuff, like setae
- Bugscope Teamalso, mold spores
- Bugscope Teambees, which we didnt see today, are very hairy
- Studentwhat is a leafhopper
Bugscope Teamthey are little green insects that you might notice hopping in the grass, especially if you disturb it
- Bugscope Teama leafhopper is a common insects, you've seen them before
- 5:07 pm
- Studentwhats the background
- Guestwhat is the big whole in the body?
Bugscope Teamthat's where someone stuck it with a pin for a display box
- Bugscope Teaminsects have guts, just like humans do
- Bugscope Teamso when this dude got nailed, the guts probably came all out and stuff...
- Studentwho funds you guys
Bugscope Teamthe projects was originally funded years ago, but now we work simply on the side, to keep this project going. some people are woking on getting more funding though...
- Guestthat is not right!
- Bugscope Teamwe stick these insects onto double stick carbon tape. it often looks like it has popped bubbles. we also sometimes use silver paint on top of that to help 'glue' the insects down
- GuestIs this actual table salt or some other type?
Bugscope Teamthis is table salt, but from wendy's restaurant
- Studentthats crazy you should ask uncle sam
Bugscope Teamyeah, people are writing grants as we speak
- Bugscope Teamwendy's puts something in their salt that makes it look like this. other salt doesn't look so interesting
- GuestI hope you get the funding! Thank you for taking your own time to provide us with such a great science tool!!
- Guestwhat do they put in with their salt?
Bugscope Teamscott may know, but he's offline now, sorry
- Studentgood for you guys
- Bugscope Teamthanks chadvanp
- Bugscope Teamthey may put sodium azide in the salt but that is only a guess
- Bugscope Teamscott is back
- Studentwhat is azide
- 5:12 pm
- Bugscope Teamso you have double bonds between the N's
- Guestthank you!!
- Bugscope TeamThank You!
- Bugscope Teamthanks cindy, good work!
- TeacherI think we are done. Time to go to FAT SANDWICH COMPANY.
- Bugscope TeamI am sorry I had a tour right when you started.
- Studentof course what was i thinking
- Bugscope Teamhmmm, i'm hungry
- Studentnan3 i should of known
- Bugscope Teamgood job tony, good session
- Bugscope Teamyeah sounds good
- TeacherI've just told my undergrads here to watch Ms. Schaab's session on Thursday. in Park Ridge. Ciao!
- Bugscope Teamlater guys!
- Guestthanks bye
- Bugscope Teamremember your bugscope member page: http://bugscope.beckman.illinois.edu/members/2010-015
- Bugscope Teamnice session everyone, closing it out now
