- 7:26am
- Bugscope Team session enabled, rxl started
- 7:38am
- Bugscope Team I need to get the sample out of the hood. This will be a busy morning -- the ironworkers will be in around 8 or so to (we hope) safely hoist the new nanoCT unit into the basement and then move it into the space we're preparing for it. Later today we have a series of tours for Chicago students.
- 8:09am
- Bugscope Team Cate done fixed it Leroy.
- 8:20am
- 8:26am
- 8:35am
- 8:41am
- Bugscope Team hey there welcome to bugscowpe
- Student what is the bug suppose to be?
- Bugscope Team This is the head of a fruit fly -- the ocellus.
- Bugscope Team This is Scott, as Console, for now.
- Bugscope Team we made a lot of rock presets and finished up with a few insectos.
- 8:46am
- Bugscope Team you can now drive if you would like
- Guest Scott, can you bring up the rock/fossil we sent over? (I am a teacher for the class)
- Student could we see an eye?
- Bugscope Team controls to drive, i mean
- Bugscope Team there's a compound eye
- Student thank u
- Bugscope Team with hundreds of individual facets, called ommatidia
- Bugscope Team Holland you can drive to the fossil.
- Bugscope Team Try one of the presets.
- Bugscope Team (one of the fossil presets)
- Student well hello all
- Student is my rock there. lets take a look at it
- Bugscope Team hello there, welcome to bugscope
- Bugscope Team So you *can* drive.
- Bugscope Team you can scroll through the presets to the right and see the rock ones
- Student since i was 16
- Student Interesting....
- Bugscope Team Holland has control of the microscope.
- Bugscope Team presets 1-9 are rock/fossil
- Teacher Scott -is there a rock sample with a fossil
- Student hello
- Student gazoontight
- Student what are we looking at here?
Bugscope Team this is (was) a compound eye
- Student bug
- Bugscope Team holland, you have control of the scope, try clicking on a rock preset (1-9)
- Student im lost
- Student me 2
- Guest WHAT UPPPPPP
- Student awesome im lovin this thing
- Student meow
- Bugscope Team these are images from a electron microscope, holland is controlling the scope
- Bugscope Team alright this is the edge of an embedded shell
- Student Was this shell from the fossil we sent?
Bugscope Team yes
Bugscope Team yes, presets 1-9 are all from the rock you sent us
- Student tyler = superbad
- Bugscope Team this is on the big l' rock you sent us
- Student quit being immature people
- 8:51am
- Guest This is just so amazing. I can't believe we can really see this. Wow
- Student Oh, wow...
- Student cam we see #2
- Student can*
- Bugscope Team there was a lot of loose stuff on the fossil, and we spent a little time cleaning it up
- Bugscope Team like sand and dirt
- Student The presets on the side 1-9 are the rocks we sent? im lost
Bugscope Team yes
- Bugscope Team we sonicated it a few times
- Bugscope Team yeah Weezy. Can you see the presets to the right of the chat here?
- Student what would form something like this?
- Guest rocks are really actually pretty interesting!
- Student yes im lookin at them now
- Student me 2
- Guest its awesome
- Bugscope Team Holland is driving and has the ability to move wherever he chooses
- Student thats a she
- Bugscope Team or change mag, focus, etc.
- Bugscope Team Sorry Holland. She..
- Student What type of rock was it?
- Student enhance
- Guest enhance
- Guest enhance
- Guest Can you identify a rock for me WEEZY WEE
- Student what type of fossil do you believe this to be
- Bugscope Team well originally (nice, Bud28 Bladerunner) it was calcium carbonate
- Student BUD28!! yesss!!
- Student what type of rock is this embedded in?
- Student Originally? You mean it's not anymore?
- Student whats that crack right there
- Student whats that crack?
- Guest bud28 you sound like you know what your talking about
- 8:56am
- Student zoom in on that cracjk
- Bugscope Team Well if it is fossilized it was probably substituted for by another mineral.
- Student Are these just different sides of the rock? did you guys break the rock up to find all these or were they visable?
- Guest yes that is true scott
- Bugscope Team OOF
- Guest miss holand afterward lets look at the crystal #2
- Student what is the crack in?
- Bugscope Team Cate says Stop. Give me a hard copy.
- Bugscope Team we can't go around corners like Deckard.
- Bugscope Team it is hard to tell where the crack is - it would be good to back off a little to see where you are
- Bugscope Team Holland let us know if you need any help navigating.
- Bugscope Team looks like you are doing fine
- Bugscope Team the crack was at the edge of the shell
- Student enhance
- Student what type of shell this might be?
- Student what type of shell might this be
- Student would this be sedimentary?
- Bugscope Team it's a tiny clam shell
- Bugscope Team yes I think it would be sedimentary
- Bugscope Team there is a boatload of fossil material in this rock
- Student would it be found in shallow or deep water?
- Guest deep
- Student Can we look at #2?
- Guest very deep
- Student what is that
- Bugscope Team these look like bottlecaps
- Bugscope Team these things that look like bottle caps are coral
- Student on what
- Student what does coral consist of
- 9:01am
- Bugscope Team you can see cubic crystals in them
- Student is there any way to specify a type of coral, or is it just "coral"?
- Guest can we see further into the crystals
- Student is number 7 on the right from the San Andreas fault?
Bugscope Team no that was just the name we gave for it
- Student this sample
- Student this #3....the coral are #2....And I think all of them are from the fossil we sent
- Bugscope Team yeah the whole mini San Andreas
- Student they just gave them clever names
- Bugscope Team Thanks Thornberry.
- Student so what r we looking at now?
Bugscope Team this is coral of some sort
- Student Hes over there gettin numbers
- Student the cerrio...whats that?
- Bugscope Team if we can get your permission we'll bust this up a little after this session and see what else is in there
- Student coral
- Bugscope Team we are thinking also of putting this into the microCT
- Student I'm pretty sure we don't need the rock back....
- Student cheerio
- Student yes
- Student is there anyway we can look at 13
- Bugscope Team so we can get xray images of the interior
- Guest that'd be great!
- Guest that'd be great!
- Student where did it get the hole/dent from?
- Bugscope Team markyville Holland can drive to preset 13
- Student thank you very much for taking your time to do this
- Bugscope Team the hole is where one of the coral organisms once lived
- Student ahhh i c
- Guest Scott, can you go back to
- Guest is this rock a good find is there anything valueable in it
- Student so coral is actually a living thing
- Bugscope Team yes but we are looking at the inorganic remnants
- Student lol yeah...they live in these shell kinda things...
- Guest Scott, can be go back to sample #five
- Student what part of the coral is living?
- Guest could i sell this for money
- Bugscope Team this is a little tricky to do with the SEM
- Student Joshua Klienschmitt= robin-yo-hood
- Bugscope Team prob'ly not that valuable but cool to image in parts
- Student is bugscope only in gray scale?
Bugscope Team yes, but we can do elemental analysis on the images, and then false color the image after the fact.
- 9:07am
- Student yes
- Bugscope Team we are using electrons, not light, to collect the images
- Student with all these fossils so close together, were they around the same time period?
Bugscope Team they are probably from the same coral
- Student and did they live in close relation?
- Bugscope Team the samples are in a vacuum chamber and we are beaming 5 kV electrons at them
- Guest Scott, can we go back to sample number five that we sent in, teacher requesting
- Student All of the samples 1-9 are ours, I think....
- Bugscope Team yes, that is right, samples 1-9 are all yours, the rock you sent us
- Student Ok, so would the coral and shells form together?
- Student or apart
- Bugscope Team the little coral organisms form a CaCO3 shell to protect their soft bodies
- Guest what would you say in your expertise form this rock fossil
- Student can we look at the cheerio
- Bugscope Team we are back to preset 5
- Student could we zoom out a little
- Student what causes the little holes, are those weathering?
- Student how old do you think this fossil could possibly be
- Student really old?
- Student why is the surface wavy? what causes this formation?
- Student this is the shell
- Bugscope Team so this was part of sediment at the bottom of a stream or lake or ocean, and over time other minerals seeped in to replace the original mineral
- 9:12am
- Student can you tell about how old this fossil may be
- Guest what are we looking at now
- Student when you cleaned it, how much dirt actually came off?
Bugscope Team there was a lot of dirt that came off, we cleaned it in detergent, sonicated it a few times and picked away at a few parts
- Bugscope Team the Cheerio is back
- Student is that a sponge?
- Guest Scott, areyou able to identify the cubed objects
- Bugscope Team this looks like a diatom
- Student Is that a cherio you eat?
- Student what is a diatom
- Student yeah....a fossilized cheerio.
- Guest is it important
- Bugscope Team the cubed objects are some sort of cubic crystal, of course, not NaCl but we don't know what it is now
- Student i think u'd get a little sick if u ate it
- Student what is a diatom
- Bugscope Team later we might be able to do EDS on it and see what it is made of
- Student What is an EDS?
- Student ??
- Bugscope Team diatoms are silica skeletoned usually unicellular aquatic organisms
- Student thanks
- Bugscope Team they come in a multitude of shapes
- Student so there found in water?
- Student zoom in on the hole
- Guest what is the jagged material
- Student Did you guys plate this in gold?
- Student now was gold added to enhance the picture?
- Guest what are the holes
- Bugscope Team EDS is energy dispersive spectroscopy, which is elemental analysis
- Bugscope Team Hello all!
- Bugscope Team when we beam electrons at a sample we get x-rays back, and we can collect the energies of the x-rays and use them to determine what the sample is composed of
- Student Hello Annie
- Bugscope Team Hi Annie!
- Student whats in that hole?
- Student enhance
- Student u no
- Student this looks like a cave
- Student go inside the hole
- Guest big foot
- Student do lil organisms live in there?
- Student nick
- Student Quit being immature
- Bugscope Team Shawn they could live in here
- Student what r those lines?
- Guest what are the little lines on the rock
- 9:17am
- Bugscope Team actually we cleaned the dirt off of this sample before we put it in the 'scope
- Guest and that hole
- Student thanks scott
- Bugscope Team right now the scalebar says 2um which is about as big as a bacterium
- Bugscope Team and we might have wiped out, like, whole colonies of leprachauns
- Guest thanks cate
- Bugscope Team 1 um = one micron = one millionth of a meter
- Student really!
- Guest and bigfoot
- Student What are the lines on the rock face?
- Student ya get money
- Student lets see some wood
- Guest what type of wood is it
- Student what she said
- Guest oak i like oak
- Bugscope Team the sample is drifting a bit
- Guest Scott, is this slide number one
Bugscope Team the preset drifted a little bit, scott will find it in a sec
- Bugscope Team making it hard to image
- Student what do u mean by "drifting"?
- Student moving?
- Student was any gold added to this sample?
- Student is there any way to clear up the image more once upclose?
- Bugscope Team here is something we did not see earlier
- Student whats this an image of?
- Student wood
- Student this does not seem like wood to me
- Student the smaller ovals. what are those?
- Bugscope Team we coated the sample with gold-palladium to make it conductive
- Student why would you need it to be conductive?
- Bugscope Team you know this is like what often happens -- we see things that generate further questions
- Student §how old is it§
- Guest Scott, what didn't you see earlier
- Bugscope Team we did not see these individual circular bodies
- Guest Scott, what are the lines inside the circular areas
- 9:22am
- Student would those be more coral?
- Bugscope Team At first I thought it was where I had scraped it
- Student on the right side it looks similar to snake scales
- Bugscope Team but I think it is naturally occurring fractures
- Student looks like abdominals
- Guest what type of wood it this
- Student fractures in the rock or the wood?
- Guest can u telll
- Bugscope Team Rainman you may be correct -- we may be looking at the extended bodies of the coral organisms, fossilized
- Student how does wood become petrified
- Student § how old is it §
- Guest good q
- Guest yeah age
- Guest Scott, do you think the circular areas are individual plant cells
- Student What are those litle holes everywhere?
- Guest how does it become petrified
Bugscope Team it usually happens when the plant is underground. Mineral-rich water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay away, a stone mould forms in its place.
- Guest good question
- Student can would zoom a little more on the oval?
- Student Hi Austin, Whens Practice?
- Guest scott your smart
- Student Why are there little holes everywhere?
- Student 7:15
- Student the little holes, do those form because the material doesnt become entirely petrified?
- Student thanks
- Guest make it rain Rainman!
- Guest what are the flowing cracks
- Bugscope Team I imagine you are right -- something did not allow minerals to flow fully into the crevices
- Student can other materials rather than wood becom petrified?
- Student from the water
- 9:28am
- Guest what type of minerals
Bugscope Team most often a silicate, such as quartz
- Guest like water crevices and erosion
- Student Can other materials rather than wood become petrified scott?
- Student Pick 13
- Student 13
- Guest 13
- Guest 13
- Student 13
- Student 10
- Student 13
- Guest Schott, can we go to sample 10
- Student BOOOO 13!!
- Bugscope Team yes lots of other materials can become petrified if the conditions are right
- Student 13
- Student thanks
- Guest Scott, can you zoom out to low magnification on the bug
- Student yes i like bugs
- Student does it have fur??
- Student what type of bug is this? a fly?
- Guest what are the eyes
Bugscope Team the 2 compound eyes are the round parts on either side of its head
- Student May we go to 13 next?
- Student what happened to the antenna
- Student things u see with
- Student so what kind of bug is this?
- Guest the bulbouse part or the small dots
- Bugscope Team this does not have fur for sure
- Student how many eyes does it have?
- Guest its a flea
- Bugscope Team it has two compound eyes
- Student is this a fly of some sort
Bugscope Team This is a true bug in the order Hemiptera
- Guest compounded?
Bugscope Team it has many facets in the eye called ommatidia that each collect and image/part of an image and send it back to the brain
- Bugscope Team Not Stephanie: If you like bugs, then you will really like the book -- Buzzwords by May Berenbaum, a terrific scientist that studies bugs for living.
- Student its a bug
- Guest its missing an antenna. i wonder what happened....
- Student what are the tiny strans coming off of the legs and such?
- Guest Scott, can you zoon into the mouth
- Guest many eyes
- Bugscope Team this is a true bug -- hemiptera
- Student thanks
- Student ill buy it
- Student its like a bunch of little eyes combined into one....
- Student how many facets make each eye?
- Bugscope Team Holland this is as much as we can see of the tip of the piercing mouthparts
- Student what r facets?
- 9:33am
- Bugscope Team facets are 'little faces,' as in diamond facets
- Guest or mouth
- Guest scott, does the mouth of the bug have actual teech
Bugscope Team Not this insect. Their mouths are modified for sucking.
- Student how big is the bugs brain?
- Student is himiptera a species of some sort
Bugscope Team Hemiptera is an order
- Student small
- Guest its only about the size of a pind head Robin
- Bugscope Team Hemiptera means half wing.
- Student can they think
Bugscope Team That is an area of active research....they can respond to stimuli, and they can learn, but we don't have a lot of evidence that they can actually think about something, and figure out what the best strategy is. They don't plan for the future. Their behaviors are mostly hardwired.
- Student what does that mean
- Student is this a organism the students there are doing or did someone else send this in??
Bugscope Team this is from our own personal bug stock that we have
- Guest so if they see 360 you cant sneek up on them and kill them very well
- Bugscope Team ptera means wing and hemi means half
- Student thanks scott
- Student is this bug native to indiana
- Student where is this but native to
- Student where is the bug native
- Student bug**
- Student is this a common type of bug?
- Student Scott, are these students there are doing, or another schools?
- Guest sucking what blood?
Bugscope Team human or animal
- Bugscope Team so this does not have teeth but has a sharp inner portion of the proboscis that is hardened and has serrated edges like a steak knife
- Student what IS this bug
- Bugscope Team this is a common type of bug and in this case really is a bug
- Student what other insects fall into the order of Himiptera?
Bugscope Team stink bug, leafhopper, shield bug, aphids, cicadas, bed bugs, and kissing bugs
- Student this is like the mosqitous from bugs life
- Student leafbugs, I think....
- Student alright you told me that this bug was a hemiptera but do you know the actual name of this bug
Bugscope Team I think this is a plant bug in the family Miridae, but I am not 100% positive
- Student And cicadas....i just googled it
- Bugscope Team they are differentiated from other insects by their mouthparts and by the way their elytra covers the wing
- Student What times lunch?
- Student Im here to save the day
- Guest so exactly how big is this bug
- Bugscope Team the elytra is the hard shell over the wing, like in a ladybug
- Student is this bug native to the midwest and or all around the world
- Student 13!!!
- Guest can we see a huge bee
Bugscope Team sorry we dont have any bees in the microscope right now
- Student 13
- Student thanks annie
- Student can we see 13 please
- Guest like the giant black and yellow ones
- Student 13
- Guest and the sgtinger
- Bugscope Team okay moving to preset 13
- Guest oh
- Bugscope Team which is a crustacean
- 9:38am
- Student Yayyy
- Guest like a yellowjack
- Guest those are huge
- Guest you scientist need a bee
Bugscope Team Dark Knight: If you visit a natural history museum, then you can see many kinds of bugs. You are right about bee. Honey Bees are very popular for studying at UIUC. Why would that be?
- Student what are the tiny Satae on their legs used for??
- Student what would a cicada killer be classified as?
Bugscope Team It is a Hymenoptera in the family Specidae
- Student wow wat are the litle thornlike things hanging from the shell
- Bugscope Team cicada killer is a hornet
Bugscope Team Not a hornet...hornets are in the family Vespidae
- Bugscope Team Annie...
- Student can i take control?
- Bugscope Team like a mondo bigboy wasp
- Guest because they are so common in our area
- Bugscope Team okay Spiderman
- Guest because they are more interesting and dangerous killer bees are know to kill people
Bugscope Team Dark Knight: There was a PBS show on Honey Bee. You can get some details about UIUC research at: http://www.life.uiuc.edu/robinson/
- Student yes nick i agree
- Guest i want a bug scope
- Guest price?
- Student are the shells of this insect used for a protection?
Bugscope Team Yes, the exoskeleton of insect protects the insect from dehydration and other injury. It is also the first line of defense against pathogens.
- Student why do you put them on their back?
Bugscope Team usually the more interesting parts like their legs and eyes are best seen when they are on their backs
- Student Whens lunch Mrs. Krucina?
- Student ur making me hungary
- Guest and we study chitin and use it for police armour
- Bugscope Team we mount them on their backs so you can see the limbs and the mouthparts
- Guest like kevlar
- Student spider man is frozen, can i take control?
Bugscope Team go for it
- Student yeah....its the new kevlar....
- 9:43am
- Student can someone answer my questions please?
Bugscope Team yup, just did.
- Bugscope Team Spiderman are you not able to drive because of the way we have things set up?
- Guest can chitin be transformed into an armour wore by humans
- Bugscope Team Sorry marky Mark
- Guest like we develop spider web to develop armour
- Guest or fabric
- Student I dont know waht happened
- Bugscope Team spider silk is really strong like steel and it is lighter than steel
- Bugscope Team it is already used to help render explosives harmless
- Bugscope Team chitocan
- Bugscope Team chitosan
- Student what are the litle thornlike haris on the shell?
- Bugscope Team Often it takes me a few minutes to answer questions because I am trying to be as complete as possible. Please be patient.
- Student hairs not haris
- Student lol
- Guest see guys, bugs are good!
- Guest really chitosan render explosive harmless how?
- Bugscope Team they are tiny setae that may help prevent dirt from getting into the plates
- Student bugs r awesome
- Student Thanks Scott...it was real scope ya out later!
- Student so the exoskeleton is actually plates?
- Student Go to 2
- Guest if we can make chitosan armour for vehicles then they cant be harmed by bombs
- Student Cam we view the salt cond.?
- Bugscope Team Weezy Wee: You can also download your own copy of virtual scope via -- http://virtual.itg.uiuc.edu/
- Bugscope Team thanks for coming to bugscope 40oz and weezy
- Bugscope Team you have control rainman
- Student what is a setae?
Bugscope Team insect hairs, they are to help the insect sense the environment around them
- Bugscope Team I think the chitosan mixes with the chemicals and makes them so they are less volatile
- Bugscope Team setae are the tiny hairlike things
- Guest how can u transform small chitosan into an armour
- Student the presents dont seem to work
Bugscope Team we are going to get them to work again,hang on
- Student Thank you everyone for your time today
- Student preset*
- Guest volatile?
- 9:48am
- Guest waht chemicals
- Student acid solfate calcium
- Bugscope Team the chemical components of the explosives are apparently coated with the chitin derivative chitosan so that they are not in such close proximity
- Bugscope Team and that prevents them from being volatile in that sense of the word
- Bugscope Team where volatile means ready to explode
- Guest laymen terms
- Guest volatile??????
- Bugscope Team volatile to a chemist would mean that something evaporates easily
- Student is this the salt
- Guest thanks scott'
- Guest how would u incorporate something like that
- Student what formed these crystals?
- Bugscope Team these are cubic crystals
- Guest to help people
- Student of what
- Student No
- Bugscope Team we will have to do EDS to determine what these crystals are composed mof
- 9:53am
- Bugscope Team of
- Student what are the crystals composed of
Bugscope Team we dont know, we would have to analyze it through EDS
- Student oh ok
- Bugscope Team they resemble NaCl but are not likely
- Student Yes i am
- Student howdy all
- Guest then what
- Student EDS?
Bugscope Team energy dispersive spectroscopy. it is where the microscope reads the xray energies coming off the sample
- Student Knights Unite!!!
- Student so you can tell what they are composed of by the energy it reads?
- Student will we be able to tell what the crystals are later?
- Student could you post the EDS results here so we could see it later?
Bugscope Team we might be able to, I'll leave that to scott
- Student will it be posted after the EDS scan?
- Student when are you gonna do EDS to determine the crystals?
- Teacher Scott - we will sign off soon at 10am your time - thanks so much - Bulldog
- Student what she said
- Bugscope Team Thanks Bob.
- Student hurray
- Student thanks for all you help i really appreciate it
- Student thanks
- Student THANKS FOR EVERYTHING!!!
- Guest thanks scottyknight
- Student ive learned a lot of new things
- Student thank you for all this interesting magnifications
- Bugscope Team We can check it out when we get done this morning and send Bob/Holland the results
- Student Thanks for looking at those samples for us, you were really helpful
- Student are these naturally occuring?
Bugscope Team yes we think so, we didnt do this when cleaning
- Guest scottyknight
- Student You guys rock, thanks for your time!
- Bugscope Team yes these are naturally occurring
- Guest saholland@avon-schools.org
- 9:58am
- Bugscope Team hey cool Thanks Holland
- Student ok thx
- Student day
- Bugscope Team alright we are over and out...
- Bugscope Team ok we have the email and will do EDS later
- Bugscope Team thank you annie and umesh, i am closing the session down now
- Bugscope Team Thanks, Cate. Thanks, Annie (all the best in CA), and thanks Scott. Talk to you all later.
