- 7:26 am
- Bugscope Teamsession enabled, rxl started
- 7:38 am
- Bugscope TeamI 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.
- 8:09 am
- Bugscope TeamCate done fixed it Leroy.
- 8:20 am
- 8:26 am
- 8:35 am
- 8:41 am
- Bugscope Teamhey there welcome to bugscowpe
- Studentwhat is the bug suppose to be?
- Bugscope TeamThis is the head of a fruit fly -- the ocellus.
- Bugscope TeamThis is Scott, as Console, for now.
- Bugscope Teamwe made a lot of rock presets and finished up with a few insectos.
- 8:46 am
- Bugscope Teamyou can now drive if you would like
- GuestScott, can you bring up the rock/fossil we sent over? (I am a teacher for the class)
- Studentcould we see an eye?
- Bugscope Teamcontrols to drive, i mean
- Bugscope Teamthere's a compound eye
- Studentthank u
- Bugscope Teamwith hundreds of individual facets, called ommatidia
- Bugscope TeamHolland you can drive to the fossil.
- Bugscope TeamTry one of the presets.
- Bugscope Team(one of the fossil presets)
- Studentwell hello all
- Studentis my rock there. lets take a look at it
- Bugscope Teamhello there, welcome to bugscope
- Bugscope TeamSo you *can* drive.
- Bugscope Teamyou can scroll through the presets to the right and see the rock ones
- Studentsince i was 16
- StudentInteresting....
- Bugscope TeamHolland has control of the microscope.
- Bugscope Teampresets 1-9 are rock/fossil
- TeacherScott -is there a rock sample with a fossil
- Studenthello
- Studentgazoontight
- Studentwhat are we looking at here?
Bugscope Teamthis is (was) a compound eye
- Studentbug
- Bugscope Teamholland, you have control of the scope, try clicking on a rock preset (1-9)
- Studentim lost
- Studentme 2
- GuestWHAT UPPPPPP
- Studentawesome im lovin this thing
- Studentmeow
- Bugscope Teamthese are images from a electron microscope, holland is controlling the scope
- Bugscope Teamalright this is the edge of an embedded shell
- StudentWas this shell from the fossil we sent?
Bugscope Teamyes
Bugscope Teamyes, presets 1-9 are all from the rock you sent us
- Studenttyler = superbad
- Bugscope Teamthis is on the big l' rock you sent us
- Studentquit being immature people
- 8:51 am
- GuestThis is just so amazing. I can't believe we can really see this. Wow
- StudentOh, wow...
- Studentcam we see #2
- Studentcan*
- Bugscope Teamthere was a lot of loose stuff on the fossil, and we spent a little time cleaning it up
- Bugscope Teamlike sand and dirt
- StudentThe presets on the side 1-9 are the rocks we sent? im lost
Bugscope Teamyes
- Bugscope Teamwe sonicated it a few times
- Bugscope Teamyeah Weezy. Can you see the presets to the right of the chat here?
- Studentwhat would form something like this?
- Guestrocks are really actually pretty interesting!
- Studentyes im lookin at them now
- Studentme 2
- Guestits awesome
- Bugscope TeamHolland is driving and has the ability to move wherever he chooses
- Studentthats a she
- Bugscope Teamor change mag, focus, etc.
- Bugscope TeamSorry Holland. She..
- StudentWhat type of rock was it?
- Studentenhance
- Guestenhance
- Guestenhance
- GuestCan you identify a rock for me WEEZY WEE
- Studentwhat type of fossil do you believe this to be
- Bugscope Teamwell originally (nice, Bud28 Bladerunner) it was calcium carbonate
- StudentBUD28!! yesss!!
- Studentwhat type of rock is this embedded in?
- StudentOriginally? You mean it's not anymore?
- Studentwhats that crack right there
- Studentwhats that crack?
- Guestbud28 you sound like you know what your talking about
- 8:56 am
- Studentzoom in on that cracjk
- Bugscope TeamWell if it is fossilized it was probably substituted for by another mineral.
- StudentAre these just different sides of the rock? did you guys break the rock up to find all these or were they visable?
- Guestyes that is true scott
- Bugscope TeamOOF
- Guestmiss holand afterward lets look at the crystal #2
- Studentwhat is the crack in?
- Bugscope TeamCate says Stop. Give me a hard copy.
- Bugscope Teamwe can't go around corners like Deckard.
- Bugscope Teamit is hard to tell where the crack is - it would be good to back off a little to see where you are
- Bugscope TeamHolland let us know if you need any help navigating.
- Bugscope Teamlooks like you are doing fine
- Bugscope Teamthe crack was at the edge of the shell
- Studentenhance
- Studentwhat type of shell this might be?
- Studentwhat type of shell might this be
- Studentwould this be sedimentary?
- Bugscope Teamit's a tiny clam shell
- Bugscope Teamyes I think it would be sedimentary
- Bugscope Teamthere is a boatload of fossil material in this rock
- Studentwould it be found in shallow or deep water?
- Guestdeep
- StudentCan we look at #2?
- Guestvery deep
- Studentwhat is that
- Bugscope Teamthese look like bottlecaps
- Bugscope Teamthese things that look like bottle caps are coral
- Studenton what
- Studentwhat does coral consist of
- 9:01 am
- Bugscope Teamyou can see cubic crystals in them
- Studentis there any way to specify a type of coral, or is it just "coral"?
- Guestcan we see further into the crystals
- Studentis number 7 on the right from the San Andreas fault?
Bugscope Teamno that was just the name we gave for it
- Studentthis sample
- Studentthis #3....the coral are #2....And I think all of them are from the fossil we sent
- Bugscope Teamyeah the whole mini San Andreas
- Studentthey just gave them clever names
- Bugscope TeamThanks Thornberry.
- Studentso what r we looking at now?
Bugscope Teamthis is coral of some sort
- StudentHes over there gettin numbers
- Studentthe cerrio...whats that?
- Bugscope Teamif we can get your permission we'll bust this up a little after this session and see what else is in there
- Studentcoral
- Bugscope Teamwe are thinking also of putting this into the microCT
- StudentI'm pretty sure we don't need the rock back....
- Studentcheerio
- Studentyes
- Studentis there anyway we can look at 13
- Bugscope Teamso we can get xray images of the interior
- Guestthat'd be great!
- Guestthat'd be great!
- Studentwhere did it get the hole/dent from?
- Bugscope Teammarkyville Holland can drive to preset 13
- Studentthank you very much for taking your time to do this
- Bugscope Teamthe hole is where one of the coral organisms once lived
- Studentahhh i c
- GuestScott, can you go back to
- Guestis this rock a good find is there anything valueable in it
- Studentso coral is actually a living thing
- Bugscope Teamyes but we are looking at the inorganic remnants
- Studentlol yeah...they live in these shell kinda things...
- GuestScott, can be go back to sample #five
- Studentwhat part of the coral is living?
- Guestcould i sell this for money
- Bugscope Teamthis is a little tricky to do with the SEM
- StudentJoshua Klienschmitt= robin-yo-hood
- Bugscope Teamprob'ly not that valuable but cool to image in parts
- Studentis bugscope only in gray scale?
Bugscope Teamyes, but we can do elemental analysis on the images, and then false color the image after the fact.
- 9:07 am
- Studentyes
- Bugscope Teamwe are using electrons, not light, to collect the images
- Studentwith all these fossils so close together, were they around the same time period?
Bugscope Teamthey are probably from the same coral
- Studentand did they live in close relation?
- Bugscope Teamthe samples are in a vacuum chamber and we are beaming 5 kV electrons at them
- GuestScott, can we go back to sample number five that we sent in, teacher requesting
- StudentAll of the samples 1-9 are ours, I think....
- Bugscope Teamyes, that is right, samples 1-9 are all yours, the rock you sent us
- StudentOk, so would the coral and shells form together?
- Studentor apart
- Bugscope Teamthe little coral organisms form a CaCO3 shell to protect their soft bodies
- Guestwhat would you say in your expertise form this rock fossil
- Studentcan we look at the cheerio
- Bugscope Teamwe are back to preset 5
- Studentcould we zoom out a little
- Studentwhat causes the little holes, are those weathering?
- Studenthow old do you think this fossil could possibly be
- Studentreally old?
- Studentwhy is the surface wavy? what causes this formation?
- Studentthis is the shell
- Bugscope Teamso 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
- 9:12 am
- Studentcan you tell about how old this fossil may be
- Guestwhat are we looking at now
- Studentwhen you cleaned it, how much dirt actually came off?
Bugscope Teamthere 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 Teamthe Cheerio is back
- Studentis that a sponge?
- GuestScott, areyou able to identify the cubed objects
- Bugscope Teamthis looks like a diatom
- StudentIs that a cherio you eat?
- Studentwhat is a diatom
- Studentyeah....a fossilized cheerio.
- Guestis it important
- Bugscope Teamthe cubed objects are some sort of cubic crystal, of course, not NaCl but we don't know what it is now
- Studenti think u'd get a little sick if u ate it
- Studentwhat is a diatom
- Bugscope Teamlater we might be able to do EDS on it and see what it is made of
- StudentWhat is an EDS?
- Student??
- Bugscope Teamdiatoms are silica skeletoned usually unicellular aquatic organisms
- Studentthanks
- Bugscope Teamthey come in a multitude of shapes
- Studentso there found in water?
- Studentzoom in on the hole
- Guest what is the jagged material
- StudentDid you guys plate this in gold?
- Studentnow was gold added to enhance the picture?
- Guestwhat are the holes
- Bugscope TeamEDS is energy dispersive spectroscopy, which is elemental analysis
- Bugscope TeamHello all!
- Bugscope Teamwhen 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
- StudentHello Annie
- Bugscope TeamHi Annie!
- Studentwhats in that hole?
- Studentenhance
- Studentu no
- Studentthis looks like a cave
- Studentgo inside the hole
- Guestbig foot
- Studentdo lil organisms live in there?
- Studentnick
- StudentQuit being immature
- Bugscope TeamShawn they could live in here
- Studentwhat r those lines?
- Guestwhat are the little lines on the rock
- 9:17 am
- Bugscope Teamactually we cleaned the dirt off of this sample before we put it in the 'scope
- Guestand that hole
- Studentthanks scott
- Bugscope Teamright now the scalebar says 2um which is about as big as a bacterium
- Bugscope Teamand we might have wiped out, like, whole colonies of leprachauns
- Guestthanks cate
- Bugscope Team1 um = one micron = one millionth of a meter
- Studentreally!
- Guestand bigfoot
- StudentWhat are the lines on the rock face?
- Studentya get money
- Studentlets see some wood
- Guestwhat type of wood is it
- Studentwhat she said
- Guestoak i like oak
- Bugscope Teamthe sample is drifting a bit
- GuestScott, is this slide number one
Bugscope Teamthe preset drifted a little bit, scott will find it in a sec
- Bugscope Teammaking it hard to image
- Studentwhat do u mean by "drifting"?
- Studentmoving?
- Studentwas any gold added to this sample?
- Studentis there any way to clear up the image more once upclose?
- Bugscope Teamhere is something we did not see earlier
- Studentwhats this an image of?
- Studentwood
- Studentthis does not seem like wood to me
- Studentthe smaller ovals. what are those?
- Bugscope Teamwe coated the sample with gold-palladium to make it conductive
- Studentwhy would you need it to be conductive?
- Bugscope Teamyou know this is like what often happens -- we see things that generate further questions
- Student§how old is it§
- GuestScott, what didn't you see earlier
- Bugscope Teamwe did not see these individual circular bodies
- GuestScott, what are the lines inside the circular areas
- 9:22 am
- Studentwould those be more coral?
- Bugscope TeamAt first I thought it was where I had scraped it
- Studenton the right side it looks similar to snake scales
- Bugscope Team but I think it is naturally occurring fractures
- Studentlooks like abdominals
- Guestwhat type of wood it this
- Studentfractures in the rock or the wood?
- Guestcan u telll
- Bugscope TeamRainman you may be correct -- we may be looking at the extended bodies of the coral organisms, fossilized
- Studenthow does wood become petrified
- Student§ how old is it §
- Guestgood q
- Guestyeah age
- GuestScott, do you think the circular areas are individual plant cells
- StudentWhat are those litle holes everywhere?
- Guesthow does it become petrified
Bugscope Teamit 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.
- Guestgood question
- Studentcan would zoom a little more on the oval?
- StudentHi Austin, Whens Practice?
- Guestscott your smart
- StudentWhy are there little holes everywhere?
- Student7:15
- Studentthe little holes, do those form because the material doesnt become entirely petrified?
- Studentthanks
- Guestmake it rain Rainman!
- Guestwhat are the flowing cracks
- Bugscope TeamI imagine you are right -- something did not allow minerals to flow fully into the crevices
- Studentcan other materials rather than wood becom petrified?
- Studentfrom the water
- 9:28 am
- Guestwhat type of minerals
Bugscope Teammost often a silicate, such as quartz
- Guestlike water crevices and erosion
- StudentCan other materials rather than wood become petrified scott?
- StudentPick 13
- Student13
- Guest13
- Guest13
- Student13
- Student10
- Student13
- GuestSchott, can we go to sample 10
- StudentBOOOO 13!!
- Bugscope Teamyes lots of other materials can become petrified if the conditions are right
- Student13
- Studentthanks
- GuestScott, can you zoom out to low magnification on the bug
- Studentyes i like bugs
- Studentdoes it have fur??
- Studentwhat type of bug is this? a fly?
- Guestwhat are the eyes
Bugscope Teamthe 2 compound eyes are the round parts on either side of its head
- StudentMay we go to 13 next?
- Studentwhat happened to the antenna
- Studentthings u see with
- Studentso what kind of bug is this?
- Guestthe bulbouse part or the small dots
- Bugscope Teamthis does not have fur for sure
- Studenthow many eyes does it have?
- Guestits a flea
- Bugscope Teamit has two compound eyes
- Studentis this a fly of some sort
Bugscope TeamThis is a true bug in the order Hemiptera
- Guestcompounded?
Bugscope Teamit 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 TeamNot Stephanie: If you like bugs, then you will really like the book -- Buzzwords by May Berenbaum, a terrific scientist that studies bugs for living.
- Studentits a bug
- Guestits missing an antenna. i wonder what happened....
- Studentwhat are the tiny strans coming off of the legs and such?
- GuestScott, can you zoon into the mouth
- Guestmany eyes
- Bugscope Teamthis is a true bug -- hemiptera
- Studentthanks
- Studentill buy it
- Studentits like a bunch of little eyes combined into one....
- Studenthow many facets make each eye?
- Bugscope TeamHolland this is as much as we can see of the tip of the piercing mouthparts
- Studentwhat r facets?
- 9:33 am
- Bugscope Teamfacets are 'little faces,' as in diamond facets
- Guestor mouth
- Guestscott, does the mouth of the bug have actual teech
Bugscope TeamNot this insect. Their mouths are modified for sucking.
- Studenthow big is the bugs brain?
- Studentis himiptera a species of some sort
Bugscope TeamHemiptera is an order
- Studentsmall
- Guestits only about the size of a pind head Robin
- Bugscope TeamHemiptera means half wing.
- Studentcan they think
Bugscope TeamThat 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.
- Studentwhat does that mean
- Studentis this a organism the students there are doing or did someone else send this in??
Bugscope Teamthis is from our own personal bug stock that we have
- Guestso if they see 360 you cant sneek up on them and kill them very well
- Bugscope Teamptera means wing and hemi means half
- Studentthanks scott
- Studentis this bug native to indiana
- Studentwhere is this but native to
- Studentwhere is the bug native
- Studentbug**
- Studentis this a common type of bug?
- StudentScott, are these students there are doing, or another schools?
- Guestsucking what blood?
Bugscope Teamhuman or animal
- Bugscope Teamso 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
- Studentwhat IS this bug
- Bugscope Teamthis is a common type of bug and in this case really is a bug
- Studentwhat other insects fall into the order of Himiptera?
Bugscope Teamstink bug, leafhopper, shield bug, aphids, cicadas, bed bugs, and kissing bugs
- Studentthis is like the mosqitous from bugs life
- Studentleafbugs, I think....
- Studentalright you told me that this bug was a hemiptera but do you know the actual name of this bug
Bugscope TeamI think this is a plant bug in the family Miridae, but I am not 100% positive
- StudentAnd cicadas....i just googled it
- Bugscope Teamthey are differentiated from other insects by their mouthparts and by the way their elytra covers the wing
- StudentWhat times lunch?
- StudentIm here to save the day
- Guestso exactly how big is this bug
- Bugscope Teamthe elytra is the hard shell over the wing, like in a ladybug
- Studentis this bug native to the midwest and or all around the world
- Student13!!!
- Guestcan we see a huge bee
Bugscope Teamsorry we dont have any bees in the microscope right now
- Student13
- Studentthanks annie
- Studentcan we see 13 please
- Guestlike the giant black and yellow ones
- Student13
- Guestand the sgtinger
- Bugscope Teamokay moving to preset 13
- Guestoh
- Bugscope Teamwhich is a crustacean
- 9:38 am
- StudentYayyy
- Guestlike a yellowjack
- Guestthose are huge
- Guestyou scientist need a bee
Bugscope TeamDark 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?
- Studentwhat are the tiny Satae on their legs used for??
- Studentwhat would a cicada killer be classified as?
Bugscope TeamIt is a Hymenoptera in the family Specidae
- Studentwow wat are the litle thornlike things hanging from the shell
- Bugscope Teamcicada killer is a hornet
Bugscope TeamNot a hornet...hornets are in the family Vespidae
- Bugscope TeamAnnie...
- Studentcan i take control?
- Bugscope Teamlike a mondo bigboy wasp
- Guestbecause they are so common in our area
- Bugscope Teamokay Spiderman
- Guestbecause they are more interesting and dangerous killer bees are know to kill people
Bugscope TeamDark Knight: There was a PBS show on Honey Bee. You can get some details about UIUC research at: http://www.life.uiuc.edu/robinson/
- Studentyes nick i agree
- Guesti want a bug scope
- Guestprice?
- Studentare the shells of this insect used for a protection?
Bugscope TeamYes, the exoskeleton of insect protects the insect from dehydration and other injury. It is also the first line of defense against pathogens.
- Studentwhy do you put them on their back?
Bugscope Teamusually the more interesting parts like their legs and eyes are best seen when they are on their backs
- StudentWhens lunch Mrs. Krucina?
- Studentur making me hungary
- Guestand we study chitin and use it for police armour
- Bugscope Teamwe mount them on their backs so you can see the limbs and the mouthparts
- Guestlike kevlar
- Studentspider man is frozen, can i take control?
Bugscope Teamgo for it
- Studentyeah....its the new kevlar....
- 9:43 am
- Studentcan someone answer my questions please?
Bugscope Teamyup, just did.
- Bugscope TeamSpiderman are you not able to drive because of the way we have things set up?
- Guestcan chitin be transformed into an armour wore by humans
- Bugscope TeamSorry marky Mark
- Guestlike we develop spider web to develop armour
- Guestor fabric
- StudentI dont know waht happened
- Bugscope Teamspider silk is really strong like steel and it is lighter than steel
- Bugscope Teamit is already used to help render explosives harmless
- Bugscope Teamchitocan
- Bugscope Teamchitosan
- Studentwhat are the litle thornlike haris on the shell?
- Bugscope TeamOften it takes me a few minutes to answer questions because I am trying to be as complete as possible. Please be patient.
- Studenthairs not haris
- Studentlol
- Guestsee guys, bugs are good!
- Guestreally chitosan render explosive harmless how?
- Bugscope Teamthey are tiny setae that may help prevent dirt from getting into the plates
- Studentbugs r awesome
- StudentThanks Scott...it was real scope ya out later!
- Studentso the exoskeleton is actually plates?
- StudentGo to 2
- Guestif we can make chitosan armour for vehicles then they cant be harmed by bombs
- StudentCam we view the salt cond.?
- Bugscope TeamWeezy Wee: You can also download your own copy of virtual scope via -- http://virtual.itg.uiuc.edu/
- Bugscope Teamthanks for coming to bugscope 40oz and weezy
- Bugscope Teamyou have control rainman
- Studentwhat is a setae?
Bugscope Teaminsect hairs, they are to help the insect sense the environment around them
- Bugscope TeamI think the chitosan mixes with the chemicals and makes them so they are less volatile
- Bugscope Teamsetae are the tiny hairlike things
- Guesthow can u transform small chitosan into an armour
- Studentthe presents dont seem to work
Bugscope Teamwe are going to get them to work again,hang on
- StudentThank you everyone for your time today
- Studentpreset*
- Guestvolatile?
- 9:48 am
- Guestwaht chemicals
- Studentacid solfate calcium
- Bugscope Teamthe chemical components of the explosives are apparently coated with the chitin derivative chitosan so that they are not in such close proximity
- Bugscope Teamand that prevents them from being volatile in that sense of the word
- Bugscope Teamwhere volatile means ready to explode
- Guestlaymen terms
- Guestvolatile??????
- Bugscope Teamvolatile to a chemist would mean that something evaporates easily
- Studentis this the salt
- Guestthanks scott'
- Guesthow would u incorporate something like that
- Studentwhat formed these crystals?
- Bugscope Teamthese are cubic crystals
- Guestto help people
- Studentof what
- StudentNo
- Bugscope Teamwe will have to do EDS to determine what these crystals are composed mof
- 9:53 am
- Bugscope Teamof
- Studentwhat are the crystals composed of
Bugscope Teamwe dont know, we would have to analyze it through EDS
- Studentoh ok
- Bugscope Teamthey resemble NaCl but are not likely
- StudentYes i am
- Studenthowdy all
- Guestthen what
- StudentEDS?
Bugscope Teamenergy dispersive spectroscopy. it is where the microscope reads the xray energies coming off the sample
- StudentKnights Unite!!!
- Studentso you can tell what they are composed of by the energy it reads?
- Studentwill we be able to tell what the crystals are later?
- Studentcould you post the EDS results here so we could see it later?
Bugscope Teamwe might be able to, I'll leave that to scott
- Studentwill it be posted after the EDS scan?
- Studentwhen are you gonna do EDS to determine the crystals?
- TeacherScott - we will sign off soon at 10am your time - thanks so much - Bulldog
- Studentwhat she said
- Bugscope TeamThanks Bob.
- Studenthurray
- Studentthanks for all you help i really appreciate it
- Studentthanks
- StudentTHANKS FOR EVERYTHING!!!
- Guestthanks scottyknight
- Studentive learned a lot of new things
- Studentthank you for all this interesting magnifications
- Bugscope TeamWe can check it out when we get done this morning and send Bob/Holland the results
- StudentThanks for looking at those samples for us, you were really helpful
- Studentare these naturally occuring?
Bugscope Teamyes we think so, we didnt do this when cleaning
- Guestscottyknight
- StudentYou guys rock, thanks for your time!
- Bugscope Teamyes these are naturally occurring
- Guestsaholland@avon-schools.org
- 9:58 am
- Bugscope Teamhey cool Thanks Holland
- Studentok thx
- Student day
- Bugscope Teamalright we are over and out...
- Bugscope Teamok we have the email and will do EDS later
- Bugscope Teamthank you annie and umesh, i am closing the session down now
- Bugscope TeamThanks, Cate. Thanks, Annie (all the best in CA), and thanks Scott. Talk to you all later.
