- Guest What are we looking at?
- Bugscope Team hi meg, welcome to bugscope
- Bugscope Team these are tenent setae
- Bugscope Team on a ladybug
- Guest How is the instrument moving the sample around?
Bugscope Team the sample is still, not moving at all.
- Bugscope Team well, that's not true completely
- Bugscope Team the stage does move in the X and Y and Z
- Guest I have a group who will be on line on May 2. Will they be able to move the bug?
Bugscope Team absolutely, you will have controls to move around, change the magnification, focus and brightness. you also click on any preset and it will move to that preset
- Bugscope Team i just gave you control, you should see controls on the right side now
- Bugscope Team but we'll need to take control back soon, we are setting up presets for a class coming on in 30 minutes
- Bugscope Team you getting the hang of it? any questions?
- Bugscope Team focus can be tricky,
- Bugscope Team at any time, you can click on a preset and it'll take you there
- Guest I'm impressed with what this does....is my computer slow?
Bugscope Team did you run the compatibility test yet?
- Bugscope Team you don't need a super fast computer at all. just broadband network
- Bugscope Team and there is some lag, that is totally normal. we are sending video through the internet to your browser, and that does have a little bit a lag
- Bugscope Team you just need to wait a second or so after each command you give the scope
- Bugscope Team there you go, nice focus
- Bugscope Team meg, we need to take back control now, to continue presets
- Bugscope Team you are welcome to watch the session if you want, and ask questions
- Bugscope Team you can also login early to your session as well, or any other session before yours
- Guest Thank you so very much!
- Bugscope Team you are welcome
- Bugscope Team you did great, but if you have any more questions please let us know
- Bugscope Team i see you haven't run the comat test yet, please do that before your session
- Bugscope Team http://bugscope.beckman.illinois.edu/compatibity
- Guest I'm on a differant computer than the one which we'll be using so I have someone who will test it for me. Thanks
Bugscope Team ah yes, run the test from the computer(s) you will be using for the session
- Bugscope Team you'll need to enter in your password
- Bugscope Team good thinking meg
- Guest Do I need to enter the password to watch this session?
Bugscope Team nope, as a guest you don't need a password at all
- Bugscope Team you only need your password when you run the compatibility test and for your session
- Guest I love what you do and hope we can get more schools involved.
Bugscope Team thanks meg, we've been around for 11 years. this is bugscope 2.0, much better than the last version
- Bugscope Team your students won't need the password, that is if your students are logging in separately.
- Guest Is Chas running the tool now?
- Bugscope Team nope, cate (not logged in yet) is actually controlling the scope itself, gathering the presets
- Bugscope Team once we are done with presets, cate will login and then we'll wait for the teacher/students to login
- Bugscope Team cate is a microscopist, so she is very good at finding cool/interesting places on the insects
- Guest I wrote about your outreach in the March 2010 Microscopy Today.
Bugscope Team way cool!
- Bugscope Team thank you!
- Guest We'd like to get SEMs into more schools across the country.....
Bugscope Team cool, but they cost a lot. that's part of the reason we did bugscope. students can control an ESEM as if it were in their school!
- Bugscope Team Do you have a link to that MT article?
- Guest Sure....Microscopy Today is free online and you can call up the March issue.
- Guest There are currently about11 schools actively using in-house SEMs. Volunteers and donors have made these possible.
Bugscope Team wow, 11! that is great. i wouldn't have guessed that many
- Bugscope Team hi mr. orton, welcome to bugscope
- Teacher hello
- Bugscope Team welcome welcome
- Bugscope Team we are setting up presets for your session
- Teacher students are logging in
- Student yes we are
- Student How is everyone this afternoon?
- Bugscope Team cool, welcome students!
- Bugscope Team welcome to bugscope
- Student Helllo everyone\
- Student hello
- Student thanks your the best alex
- Student Yeah, so what are we looking at exactly
Bugscope Team there are live images from an electron microscope, your teacher will be controlling it soon.
- Student i have no lue
- Student clue
- Student it looks like fins
- Bugscope Team we just have a couple more presets to get, then we'll start the session
- Bugscope Team these are buttefly scales
- Student okkay sounds goood alex
- Bugscope Team butterflies have scales all over
- Bugscope Team we are not 100% sure it's a butterfly, but we are 90% sure
- Bugscope Team it's not a moth
- Bugscope Team moth's also have lots of scales
- Student how do you know the difference
- Student oh... never mind
- Student what is this?
- Student wait, yeah how do you know the difference
Bugscope Team well, we work with entomologists and they are good at identifying insects
- Bugscope Team this is a cricket head
- Student that looks cool
- Student why does this look gray
- Student :S
- Student are the scales the same?
- Student mr orton y dnt u say anything
- Student that looks creepy what is it?
- Student He doesnt know enough...
- Bugscope Team this is a spider claw
- Student oooh kool
- Student yummy:)
- Student What kind of spider?
- Teacher it takes me longer because I care aboiut speling
Bugscope Team that's cool, no problem. i sometimes misspell things. no one is perfect
- Student how big are they?
- Student I can really tell
- Student hahahaha
- Bugscope Team WE ARE READY!!!!
- Student YAY!!!!:)
- Student yeah
- Bugscope Team mr. orton, i just unlocked the session, you should see controls on the right side of the image now
- Student is that the same for humans?
- Bugscope Team go ahead and move around, if you get lost, just click on a preset and it'll move there
- Student thats good to know
- Bugscope Team This is very cool -- I can't say I've seen a claw like this before
- Student i don't know what i'm doing.
Bugscope Team Your class is controlling an electron microscope. However, only one person can control at a time, right now it's Mr. Orton. We're here to answer questions and explain what you're seeing
- Student me niether..lol
- Bugscope Team these are all live images from an electron microscope. it's black and white because there is no light used to get the image. it's all done with electrons
- Student me ether
- Teacher let's give control to gonzagaballer
Bugscope Team they have control
- Student oh really
- Bugscope Team go ahead and ask any questions you have
- Student thats a spider claw?
- Student looks like wings
- Bugscope Team ok! gonza, you've got control of the scope now
- Bugscope Team this is a very powerful electron microscope. you can change the mag on these insects up to 40,000x
- Student kinda creepy though
- Student looks blurry
Bugscope Team sure, things can be out of focus, but there is a control for changing the focus
- Bugscope Team the scope can mag much higher than that, but for these insects, 40,000x is about the highest to get a good image
- Student what's that
- Student is the hair coarse or fine?
- Bugscope Team The hair, setae, on spiders is often incredibly complex with intricate branching and patterns. More so than any other insects I've seen
- Student yeah what is that
- Bugscope Team this is a ladybug palp
- Student palp?
Bugscope Team these vacuum cleaner nozzle looking things are used to taste or manipulate food for the ladybug
- Bugscope Team And especially around their spinnerets where the create the silk used for their webs
- Bugscope Team a palp is kind of like a tongue, it is used to taste food, but also to manipulate it
- Student ohhh
- Bugscope Team Yes, palps are kind of like extra little hands for helping shovel food into your mouth, or to taste it
- Bugscope Team notice how the palp is near the mouth area
- Student cool
- Bugscope Team that palp can taste and smell food, and also help shovel food into the mouth
- Student that looks pretty weird
- Student so kinda like tastbuds
Bugscope Team exactly!
Bugscope Team Exactly. We'd call the setae on them "chemosensory", because they give the insect chemical information
- Bugscope Team The swooping part going behind the palp is one of the two antennae
- Student tastebuds*
- Teacher nice job gonzo
- Student Chas is confusing
- Bugscope Team like, if humans didn't such long hands, they wouldn't be able to eat so well, so we'd probably need palps, little things on the side of our heads that could shovel food into our mouths
- Bugscope Team Yeah, you're doing a great job driving
- Teacher let's give control to DTMxPlatas
Bugscope Team done, DTM has control
- Student wow...
- Student rolly polly
- Student i used to think these were cute?
Bugscope Team scott, who isn't on right now says they look like mean librarians
- Student cool!!!!!!!!!!!
- Student how bout a nose?
Bugscope Team nope, no noses. insects have hair like things called setae. some setae are chemosensory and can smell things. palps also smell things, so do antennas
Bugscope Team Insects don't have noses because they don't have lungs like we do. Instead of breathing through their mouth and into lungs like we do, insects have many smaller openings called "spiracles" through which air diffuses and provides oxygen directly to the body tissues. This is less efficient than using lungs to oxygenate blood that circulates to the organs, which is part of the reason why insects are limited in size
- Student do they have eyes
Bugscope Team yep, compound eyes
- Student where
- Student whats that mean?
Bugscope Team Compound eyes differ from ours in that they're made up of many smaller facets -- each a functional primitive eye. Then their brains combine together all of the images from the primitive eyes to see the world around them, similar to how our brains merge the views from both our eyes
- Bugscope Team Yep. Rolly pollys, also called pill bugs, actually have gills on their underside which allows them to breath in moist environments
- Student ohhh,
- Student where are the eyes
Bugscope Team preset #2 is a compound eye. ask DTM to click on preset #2
- Teacher Nice work Platas!
- Bugscope Team cool!
- Bugscope Team this is a close-up of a compound eye
- Student what is this
- Bugscope Team those bumps are called ommatidia, each one has a lens in it
- Student they have hairs?
Bugscope Team yes they are short and stiff to help navigate through wind currents
- Student thats the compound eye
Bugscope Team yep
- Student ???
- Student what are the spikes
Bugscope Team those are called setae, and they are though to help the insect fly by sensing wind speed and direction
- Student are they sharp?
Bugscope Team they are pretty sharp looking, but we wouldn't be able to feel them- they are too small
- Student oh ok
- Student what insect is this
Bugscope Team click on the scale bar in the lower left of the image, that'll tell you lots of cool info about the current image
- Student what kind of spider is this
- Student does spider hair grow just like humans?
Bugscope Team I'm not sure. I don't know whether it continually grows and falls out like us or if it gets created once when the exoskeleton is formed
- Student i don't like spiders , i'm scared.
Bugscope Team sorry, it'll be okay though, the little critter is RIP
- Student wow
- Student this looks like an elephant
Bugscope Team haha it's a cricket and you can see its palps really well
- Student now what is this
- Student that helps a lot
- Student what is this for
Bugscope Team this palp helps the cricket to taste and smell its food
- Student why are they so ugly?
Bugscope Team well, they don't have mirrors that small so they have learned not to care about their looks.... :)
- Student whats that?
- Student Spiders get haircuts at the barber every two weeks
- Bugscope Team This is a haltere. It bounces back and forth during flight
- Student whats that hole thing
- Bugscope Team A fruit fly
- Student whats it 4
- Bugscope Team The motion of the haltere is sensed by the fly and it helps the fly to fly in a straight line through the air even when there are gusts of wind
- Bugscope Team It works much like a gyroscope helps a plane navigate
- Student LOL!
- Student I dont think Mr. Orton has a mirror either
- Student hahaha muchoz funnyz
- Student kool
- Student that looks pretty cool
- Teacher nice
- Student hahaha
- Teacher Shouldn't insult the man with the gradebook
Bugscope Team ha! good comeback mr. o!
- Student Why not, grade cant get any worse
- Teacher let's give control to gibby
Bugscope Team go gibby
- Bugscope Team Here you can very clearly see the array of round facets in the compound eye
- Student LOL funny
- Bugscope Team every little circle is a small eye, called an ommatidium
- Student lol
- Student thats alot of eyes!!!
- Student *potty break brb
- Bugscope Team the lenses in the compound eye are fixed, they can't move around like our lens can. so they have hundreds of lenses pointed in a curved area, that way they have good peripheral vision
- Student can we look at it a little closer
- Student so theire eyes are more powerfull then ours
Bugscope Team well, our eyes have certain abilities theirs don't. i think our eyes work for us pretty well, and compound eyes work well for insects
Bugscope Team Our eyes are very versatile, they have both near and far vision, but they require a lot of maintenence (eyelids, tears, muscles to move them, etc). Insect eyes are very low maintenance and simpler for their brains to process
- Student how many lenses do they have
Bugscope Team Some have tens, some have hundreds. It tends to depend on how important their vision is for survival. Flying insects will have more than insects which live underground in the dark
- Bugscope Team those are antennae hanging down from its head
- Student what is this
- Student i think it would be cool if we would have compound eyes to see what is like to look at things how they do
Bugscope Team i think if we suddenly had compound eyes we would be way creepy looking with these huge bulbous eyes
- Student how long do they live
- Bugscope Team some ants don't have any eyes at all, they use their chemosensory setae to follow chemical trails of their mates
- Student they dont?!
- Student oh wow
- Student why is their mouth in segments kinda
- Student whats their life span?
- Student how about if there sensory breaks
- Student how do they know where to drop
- Student what is that???
- Student those are eggs dah
Bugscope Team They are called 'lamellate' antennae, from a June beetle like Alex said. They unfold when the beetle is smelling the air.
- Bugscope Team this is the end of an antenna on a june bug, i think
- Student yea we would be ugly
Bugscope Team Some people wearing those huge wrap-around sunglasses have already achieved the look
- Student yeah i think we would look very weird
- Student whats their life span?
Bugscope Team june bugs live part of their lives as a larva, but once an adult, it'll like maybe a season, couple of months maybe?
- Student salt? thats not a bug
Bugscope Team we don't always have to look at salt. We sometimes put other interesting things in the scope for you to see
- Bugscope Team Hi all - sorry I'm a little late to your session! :)
- Student its okkay Rob nice to have you!
- Student LATE thats not good!!!!
- Teacher please give control to Cheer16
- Student like sugar
Bugscope Team We were contracted by Domino sugar once to look at some of their products for them
- Bugscope Team Cheer16 is in control!
- Student i agree with you Chas 2
- Bugscope Team :)
- Student :)
- Bugscope Team mmmm, sugar...
- Student this looks like something from the ocean
- Student i agree
- Bugscope Team We're looking at hairs on the bottom of an insect's foot, called tenant setae.
- Bugscope Team These help the insect hold onto smooth surfaces, like glass, or a smooth leaf surface.
- Student it looks like a seaenemeny
- Student don't they get worn out from walking
Bugscope Team You can think of it kind of like a koosh ball - the setae compress and curve against the substrate, and I believe they are tipped with a little ball of oil.
- Student wow thats cool
- Bugscope Team These tenant setae sometimes have pores which excrete a sticky substance to help them adhere to walls, window glass, ceilings, etc
- Bugscope Team Yes, what Chas said.
- Student ewww
- Student is this one burned
Bugscope Team it looks like it is rotting or got covered in some liquid and the liquid dried. Not a very good specimen
- Student yeah Chas
- Bugscope Team Geckos have a similar pad of hairs, but they are 10-100x smaller and rely on a dry-adhesion property unique because of their small size
- Student looks like lint or something
- Bugscope Team Hm, I think this is the broken base of an antenna.
- Student looks like a pineapple
- Bugscope Team You can see a screw head!
- Student is htat a star
- Student that
- Bugscope Team make a wish!
- Bugscope Team try not to drive off the edge.
- Teacher please give control to Liz
Bugscope Team liz has control now, go liz!
- Bugscope Team you are controlling a $600,000 microscope so be careful!!! haha
- Student why liz
Bugscope Team because liz is cool....
- Student my rims are worth that much
Bugscope Team Yeah but can't look at bugs close up with a set of 22"ers
Bugscope Team sweet
- Student i made my wish hopefully it will come true
- Student how do you know
- Student i have a bugatti veyron
Bugscope Team pretty fast/expensive car...
Bugscope Team Look up the bugatti veyron national geographic special on youtube, it's fascinating and scientifically interesting to boot!
- Student lol jk
- Student i don't think liz can handle the controls
- Student i agree with cesar21
- Student true true
- Bugscope Team liz, you are doing great!
- Bugscope Team good work, focus the other way if the first way doesn't work
- Student bye
- Student well
- Student are you sure alex
- Student its hard to control the scope
- Student thanks a lot but i have to run to another class! thanks admins
- Bugscope Team you all did great, good work
- Student THANKS!!!!:)
- Bugscope Team you are welcome
- Student hey dont be hating no liz
- Bugscope Team Great job guys, it was great to have you on
- Student now what is this??
Bugscope Team A fly to the left, and the round things are impressions/bubbles in the carbon tape used to stick the bugs down
- Teacher some have to go, but some can stay if that is alright
Bugscope Team that is totally fine, you've got the scope until 3PM central, another 30 minutes
- Student i'm not hating liz i'm hating elizabeth
- Student its a les16
- Student hey thats my sister ima tell her jst watch
- Bugscope Team This is a great close-up of a fly mouth (at the top) and the eye (at the bottom)!
- Bugscope Team notice all the setae (hairs), you'll see a lot of that on insects...
- Student thanks Chas 2 thats good to know
- Bugscope Team the setae function as sensory organs, in that they feel the environment with those setae
- Student why are u so serious les16
- Bugscope Team insects have a hard outer shell called an exoskeleton, and it can't feel anything. so those setae stick through the exoskeleton and connect to nerves underneath, and that's how it feels things
- Student thats blurry
- Bugscope Team click again to stop moving liz
- Teacher please let Les 16 have control
- Teacher buckle up!
- Bugscope Team there ya go, good work liz!
- Student its pretty cool how were able to see all those small things that the insects have
Bugscope Team right on!
- Student is it to late to get off
- Student click or ticket
Bugscope Team It doesn't rhyme unless you say 'click it or ticket'
- Student click it*
- Bugscope Team go ahead and click on a preset les16, it'll take you there
- Bugscope Team d'oh
- Bugscope Team any problems les16?
- Bugscope Team can we help?
- Student i got it now thanks
- Bugscope Team We're off in the middle between bugs. If you choose a preset from the lower right it'll get you started going from an interesting spot
- Student i don't think she knows what shes doing
- Student what is this??
Bugscope Team that looks like a piece of juju- something that isn't part of the bug like dust or dirt
Bugscope Team It's hard to say this close. I think it's a bit of crud stuck on a spider's fang.
- Student she needs more practice
- Student what is on the fang
- Student garbage
- Student so the fang isnt smooth
Bugscope Team No, the ribbing may be there to reduce friction and help it slide into the victim more easily
- Bugscope Team There's the whole fang - you can see the pore at the very tip where venom flows into a bite!
- Student smooth as the rockies
- Teacher smooth to us but not to an electron
Bugscope Team exactly, or maybe not to an insect
- Student is that hole used to extract blood
Bugscope Team No, the spider will drink that through a mouth, which is between the fangs.
- Student thats cool are all fangs like that
Bugscope Team I am not sure, but any spider that makes venom has to inject it from somewhere.
- Teacher nice job les
- Teacher PLease gice control to cesar
- Student Got to run...thanks for everything Admins!
- Bugscope Team No problem!
- Bugscope Team cesar, you've got control of the senate and the kingdom... i mean, the scope.
- Student what is htat on the top
- Student that
- Bugscope Team these bumps are the sticky tape that we stick the bugs to
- Bugscope Team it keeps the bugs still
- Student oh
- Student oh thats cool
- Student What is this
- Bugscope Team This is a scarab beetle. You can tell because the antennae look like those little combs (they're called 'lamellate').
- Student do their joints have something soft so the bones dont wear out
Bugscope Team Actually, yes. Insect joints are coated in a rubbery protein called 'resilin', which helps them move smoothly and conserves a lot of kinetic energy.
- Bugscope Team this is a june bug head
- Student i mean exoskeleton
- Student oh thanks bob i mean rob jk lol
- Bugscope Team june bugs are like beetls
- Bugscope Team well, they are beetles, a genus of scarab beetles
- Student thats good to know
- Bugscope Team You can often times see complex patterns of setae or ribbing of the exoskeleton in or around the joints which I presume also helps reduce friction
- Student oh ok thanks
- Student oh i see
- Student what is that black hole
Bugscope Team Looks like where they were mounted with a pin previously
- Student oh
- Student how does their mouth work
Bugscope Team the mouths of chewing insects work side to side, compared to our mouths. and those of insects seem much more complicated. We don't have palps to help us eat and taste food, either. Of course.
Bugscope Team One of the insects on here, the 'true bug,' has a straw instead of jaws. It sticks it inside plant stems or seeds and drinks the juices.
- Student can we take a look at the bottom???
Bugscope Team you mean the underside, which is actually the dorsal surface?
- Teacher about 3 minutes left
- Bugscope Team here you can see those lamellated antennae
- Student cool
- Bugscope Team we usually mount insects on their backs so that we see the ventral side, where almost everything is happening
- Teacher thanks alot for all your help today
- Bugscope Team this is the tip of the abdomen
- Bugscope Team Thank You!
- Teacher We need to get going guys
- Bugscope Team thanks for using bugscope today. Feel free to sign up again in the future!
- Bugscope Team your class was great
- Bugscope Team oops flexible
- Bugscope Team Thanks for the questions!
- Student thanks for the stuuf htat you thought us
- Student stuff
- Bugscope Team you are welcome les 16
- Bugscope Team good work!
- Bugscope Team mr. orton, remember, all the chat and images are saved to your member page...
- Student ok thanks ofr letting us use it
- Teacher We'll be back
- Bugscope Team http://bugscope.beckman.illinois.edu/members/2010-018
- Student bye and thanks a lot
- Bugscope Team heh sounds great, thanks
- Bugscope Team over and out...
- Teacher Have a great day
- Bugscope Team bye mr orton
