- 7:25 am
- Bugscope Teamhello katy!
- Teacherhello! this is Katy, the teacher, I'm just setting up their computers and then, if you don't mind, I'll look around to get an idea of what we
- Teacherwhat we'll look at.
- Teacherthey cannot come in (homeschool group) until 9:30am...
- 7:30 am
- Bugscope TeamKaty we are making the presets now; it'll take a few minutes...
- Teachersounds good. we're supposed to have 7 students...and me! take your time...
- 7:37 am
- 7:43 am
- 7:50 am
- 7:56 am
- Teacherthis is so cool...thanks for all of the extra specimens. I miss SEM!!!
- 8:01 am
- Bugscope Teamyou should have your pick from a lot of presets/insects
- 8:10 am
- Bugscope TeamKaty you can try driving now if you want.
- Teacherthanks-awesome...I'll play around now...
- Bugscope TeamLet us know if you have any trouble.
- Bugscope Teamthe Adjust buttons are for contrast/brightness.
- Bugscope TeamFocus is stepwise, in one direction or the other.
- Bugscope TeamWhen you click to drive you also need to click to stop.
- Bugscope Teamnice...
- 8:15 am
- Teachermost of the SEM I did back in the day (not too long ago) was not digital and we used polaroid. so, I'm impressed!
- Teacherthis is an environmental SEM, right? but are we using it as such?
Bugscope Teamwe are using it as a regular SEM and not as an ESEM right now
- Bugscope Teamlike type 55 film and sodium sulfite?
- Teacheryes, and the green scanning screen in a dark room. ;) but when I moved on to grad school, things were digital.
- Teacher(all liver or liver cells, or our 3-d liver model)
- Bugscope Teamyou cultured liver cells?
- 8:20 am
- Bugscope Teamhepatocytes
- Teacheryes, but also looked at sections after partial hepatectomy during regeneration and also after seeding cells into our bioreactor to look at cell organization.
- TeacherI cultured hepatocytes, but my focus was on the endothelial and stellate cells and their role in angiogenesis and fibrosis, etc.
- Teachernow I'm teaching! ;)
- Teacherabout research...
- Bugscope Teamit is interesting that parts of the liver die, like from drinking alcohol, and scar tissue forms, and then the liver regenerates but has to grow through the scar tissue
- Bugscope Teamis what you are doing today normal or a sideline?
- Teacheryes! but eventually cannot. the stellate cell population "activates" or changes phenotype and becomes myofibroblast-like...this in turn causes the scarring...and prevents O2 from getting to the cells, etc.
- Teacherduring normal regeneration (after parts of the liver are cut out), the stellate cells seem to partially and reversibly activate when needed but they revert back to their quiescent state. They are the "communicators" and architects of the liver.
- Teacherthese bugs are much cooler though. ;)
- Bugscope Teamthats why we look at bugs and not something else, because they are much cooler to kids
- 8:26 am
- Bugscope Teambut sometimes, like today, we put other things in the scope like salt
- Bugscope TeamHello all!
- Teacheris that "wendys" as in the restaurant or as in a person you know? ;)
Bugscope Teamthe restaurant. they have different salt then we have seen before, ther eis more structure to it
- TeacherHi Annie!
- Teacherthe students should be arriving as we speak.
- Bugscope TeamHi Annie!
- Bugscope TeamAnnie is our entomologist, connecting from California for the summer.
- Teacherhmm...that's kind of scary. how does the structure seem different? more layers of structure?
- Teachercool! now someone can answer all of the kids questions instead of google!
- Bugscope TeamWe think that there is an anti-clumping agent that makes them look like this.
- Bugscope TeamAztec salt.
- Teacherthe kids are here now....let me show them how to login in...only two laptops so they are sharing. I also have a projector screen up.
- Bugscope Teamcool beans
- 8:32 am
- Bugscope TeamHi Kev, and T.I.E.!
- Bugscope TeamLet us know when you have questions.
- StudentHi
- Studenthello!
- Bugscope TeamKaty we can also give control to a student if you would like to give them a chance to drive
- Bugscope TeamThis is salt -- sodium chloride -- from a Wendy's restaurant.
- Studentcant wait to start
- Bugscope TeamNaCl
- Studenthi T.I.E.
- Studentyo kev
- Studentwhat's up?
- Studentu r right across from us! u know!
- Bugscope TeamOOF
- Bugscope Teambetter...
- Studentyup
- Bugscope Teammuch better -- you are good at this
- Studentout of focus
- Studentthank you
- Studentthis is cool!
- Studentwhat?
- Bugscope TeamI am sitting in front of the microscope, Cate is at the computer next to the 'scope, Annie is in Cali...
- Bugscope Teamthis is salt from Wendys if you didnt already know
- Studentkev, stop talking!
- Bugscope TeamIn California where it is 6:37 am
- Studentwe knew
- Teacherwe're going to take a look at the insects we sent in and then the other cool specimens you provided.
- Bugscope Teamthis is a so-called environmental scanning electron microscope but we are using it as a normal SEM
- Studentthe salt looks cool!
- 8:37 am
- Teacherwe'll go back to that later--we think its cool too.
- Bugscope Teamthis is your spider
- Studentthe spider is scary!
- Bugscope Teamwhere the spinnerets are
- Teacherit was in my bedroom!
- Studentoh gross!!!!!!!!!!!!!!
- Bugscope Teamspider booty
- Studenteek!!!
- Teacherhey!
- Studenthahaha
- Bugscope Teamclearly when the spider is alive this is not shriveled like it is now
- Studentewww!
- StudentI killed one yesterday
- Teacherspiders eat mosquitoes which sting me and bother me a lot more than this spider.
- Bugscope Teamgood that spiderman doesn't have spinnerets
- Studentis this where the webbing stuff comes from?
- Studentyes
- Bugscope Teamyes it is hard to see the spinnerets here with all of the setae around them, but they are the smooth hairlike things
- Studentu dont know that, kev!!!
- Bugscope Teamkev was right
- Bugscope Teamthey produce different kinds of web, and some are not sticky
- Bugscope Teamthe dots are the bases of setae that have broken off
- Studentthanks scott
- Bugscope Teamyou can see that the surface of the body is infolded, quite a bit
- Studentspiders have 8 eyes
- Studentyou can tell were girls
- Bugscope Teamand when the spider was alive it would have been expanded
- 8:42 am
- Studentreally?
- Studentdo u know if this spider is a female or male
Bugscope Teamwe think it is a female
- Bugscope Teamspiders are softbodied -- they are not like most of the insects, which have exoskeletons
- Studentoh thanks
- Bugscope Teammale spiders have larger palps -- the armlike things in front of the face
- Teachermy controls disappeared
- Teacherthere they are
- Studentgood
- Bugscope Teamyou can see now that this is where one of the setae had been
- Studentwhat are setae?
Bugscope Teaminsect hairs
- Bugscope Teamspiders, you know, are very sensitive to vibration
- Studentis a setae anything like a sautay
Bugscope Teamit is pronounced see-tee
- Studentthanks
- Studentjocking!
- Bugscope Teamand the setae (see-tee) are hairlike structures that have (often) sensory functions
- Studentthats not how you spell jokeing
- Bugscope Teamsome setae (singular is seta) are chemosensory and some are mechanosensory -- like cat or rat whiskers
- StudentT.I.E can't spell!
- TeacherI heard that they help the insects stick to the wall.
Bugscope Teamsome setae do. a specific setae called tenent setae, which we have a few presets of today
- Bugscope Teamor, as Cate says, mice whiskers, to be fair
- 8:48 am
- Studentwhat is the thing in the middle of circle?
Bugscope Teamthat is a broken off seta (which is a singular setae)
- Bugscope Teamyesterday we saw tenent setae on a spider that had finer tiny setae attached to them
- Teacheroh yes! ;) they'd like to look at the spider's eyes, so I'm going to go to that preset and hand over control.
- Studentthank you cate
- Bugscope Teamgeckos have something similar but about a tenth the size
- Bugscope TeamLet us know who you would like to confer control to
- Studentwhat is that?
- Bugscope Teamthe eyes are kind of beat up looking
- Bugscope Teamfour, and two, and two
- Studentthis eye is very interesting i would like to lern more about it.
- Bugscope Teamyou can see 6 eyes in the front, and to eyes on either side on top of the head
- Bugscope TeamKev do you want to drive?
- TeacherHello, I'm Alex
- Bugscope TeamOh I see.
- TeacherKaty's letting me drive
- Bugscope TeamI don't know how much work has been done into how spiders see
- Studentno thanks
- Bugscope TeamI know that some spiders, like jumping spiders, are visual predators, and apparently can see as well as we can.
- Bugscope TeamThe eyes, when we have not coated them with gold-palladium and we are not imaging only the surface, seem to have pupils in them like people eyes
- Bugscope TeamKaty: You all are asking good questions. One comment: You will have access to all your images via the database after the session.
- Bugscope TeamAnd some spiders, like the ones that spin large elaborate webs, can hardly see at all. They sense their prey by vibration
- Studentwe had to change our name cause we loggedout
- Bugscope Teamthat is a disadvantage of SEM -- that we cannot see through things that are normally transparent.
- 8:53 am
- Bugscope TeamThere is a big black widow and a bunch of her babies (I guess) living in an upside down pot outside my house here.
- Bugscope Teamso should we ask what TIE or TIEE stands for?
- StudentT.I.E the spider is ALIVE! HA HA HA HA HA !!!!!!!!!!
- Bugscope TeamCan you save a baby for us?
- Studentwe just made it up
- Studentnice kev
- Bugscope Teamblack widows like to stay in one place, fortunately
- Bugscope TeamThey are still pretty big--and I am not 100 sure they are the babies. But, I can try to catch one without getting bitten
- Studenta black widow!? i do not want one of those!!!!!!
- StudentT.I.E.E. out, I know where you live!
- Studenthaha kev i live with you!
- Bugscope TeamMaybe..I think they are giant babies
- StudentI ment look out!
- Bugscope Teamthey are really beautiful -- they are shiny like wet plastic
- Bugscope TeamI hope they don't eat her
- Studentwhat are shiny?
Bugscope TeamBlack widow females
- Bugscope Teamthis is some juju on one of the eyes
- Studentwhat is that?
- Bugscope Teamblack widows are shiny
- 8:58 am
- Bugscope Teamuh-huh, yes she is really gorgeous. We had one living in the house last year and one in the car too.
- Bugscope Teamoh maybe the other ones are boys
- Bugscope TeamThey are not agressive at all
- Studentwhat is juju?
- Studentdoes the female black widow eat the male black widows?
Bugscope TeamIf she is hungry and he is not fast enough to get away
- Bugscope TeamI have one of those jumping spiders living in my car, in the trunk
- Studentoh
- Bugscope Teamjuju is our word for slime or other unidentifiable debris
- TeacherWhat is the juju
- Studenti hate jumping spiders! why dont you take it out?
Bugscope Teamscott like to keep pet spiders
- Bugscope TeamSpiders are usually not aggressive at all. They would rather just run away than have to bite you. The venom is expensive to make, and they certainly can't eat you.
- Studentoh, thanks.
- Bugscope Teamin this case it is some oil or something that is on the eye and charging up with electrons
- Bugscope TeamI just had one of my favorite spiders, from this building, die
- Studentso do I
- Student hey we asked that question kev!
- Bugscope Teamso of course Cate cut it in half and put it on this stub
- Studentwhat is that hair?
- Studentwhy do you keep spiders for pets? do you study them?
- Bugscope Teammore sensory setae
- Studentthanks
- Bugscope Teamyou can see one of its claws in the lower left corner
- Studenti see it! i see it!
- 9:03 am
- Bugscope Teamthis is the season for bugscope, but it is not what we do all of the time
- Bugscope Teamtheres some spider fangs
- Studentlook at those fanges
- Studentlook out! T.I.E.E.
- Studentthats not how you spell fangs
- Studentwhat us SEM, TEMetc.?
Bugscope TeamSEM is what we are using now, the Scanning Electron Microscope, and the TEM is another electron microscope we have that stands for Transmission Electron Microscope
- Studentis that it's mouth?
- Bugscope Teamits hard to see the end of the fangs on spiders. I would love to see the venom pores
- Studenti would 2 cate
- Bugscope Teamsometimes when a male spider wants to mate with a female spider and not get devoured, he will make a packet of web and stick it on the chelicerae so they cannot open and she cannot bite
- Studentwhat is the chelicerae?
Bugscope Teamthose are the buck teeth looking things where the fangs are attached
- Studentcool
- Bugscope Teamwe had read about that and then one week we found a female spider with a wad of web stuck right between the chelicerae
- Bugscope Teamthe chelicerae, or chelicers, are the jaw-like things that the fangs are attached to
- Studentis the spider on it's back?
- Studentyou are me understand cate thank you
- Bugscope Teamas Cate says they look like buck teeth
- 9:08 am
- Studentwhy are the spiders legs curled up? is it dead?
- Bugscope Teamyes it is on its back -- we often mount bugs, etc., on the dorsal side so we can view the ventral side
- TeacherHow do we capture images?
Bugscope Teamyou are capturing images as you are looking at them. All your images are saved as we go along and can be viewed from your teacher page in the transcript
- Bugscope Teamyeah sorry it is dead -- one of the spiders you sent was still alive
- Studentopps!
- Bugscope Teamyou can imagine that it would be hard to image a living spider
- Studentthanks Scott
- Bugscope Teamthis is the spider you sent, the dead one
- Studentthe spider looks squished!
Bugscope Teamyeah..the abdomen deflates when they die
- Studentis that its butt
- Bugscope Teamyes not to put too fine a point on it
- Bugscope Teamas Dickens would say
- Bugscope Teamoof
- Bugscope TeamOOF
- Bugscope Teamyay!
- Studentwhat are those two half circles?
- TeacherWhat is the part we're looking at now?
- Studentthat's better
- Bugscope Teamsome of these spinnerets produce sticky web and some produce smooth web
- Studentwhat are the little tiny circles
Bugscope Teamthose are where the setae broke off
- 9:13 am
- Student?
- Bugscope Teamyou can tell that the tiny circles are where setae were lost
- Studentok
- Studentwow!
- Bugscope Teamspiders, if they get stuck in their own web, can eat their way out
- Studentyes i can see into the holes
- Bugscope Teamthey also recycle their web by eating it
- Studentthats one way to recycle!
- Studentwish we could do that!
- Bugscope Teamnote that Spiderman does not seem to recycle. And Peter Parker does not have web for breakfast.
- Bugscope Teamthis is one of the claws; we were thinking that the spider could slide along the nonsticky web with it.
- Bugscope Teamspider silk is 5 times as strong as steel
- Bugscope Teamit has a built-in comb
- Studentyou know what else i noticed, scott loves spiderman
- Bugscope TeamI just had some web with my yogurt and cereal...mmm
- Bugscope Teamnot really
- Studentgood
- Bugscope TeamI like Iron Man now.
- Studenti want to have that for lunch!
- StudentOK
- Studentone order of a hamburger and web, please!
- 9:19 am
- Studentwhat are we looking at now?
- Bugscope Teamon Wikipedia it says that 16 ounces of spider web could circle the world
- Bugscope TeamCool Brett let us know if you have questions.
- Studentreally?
- Studentwhat is this
- Bugscope Teamthis is a caterpillar
- Studentdo spiders have teeth?
Bugscope Teamno, they have fangs that they use to inject venom into their prey. The venom liquifies the inside of the prey's body, and the spider sucks down the juices. No chewing involved.
- Bugscope Teamspiders have fangs, but they do not chew
- Studentwe have now become T.I.E.E.K.! (kev joined us!)
- Studentspiders have fangs, right?
- Bugscope Teamspiders inject venom into their prey that immobilizes them and also liquefies the insides of the prey.
- Bugscope Teamspiders drink their prey like a milkshake
- StudentHow many fangs do spiders have?
- Bugscope Teamtwo
- Studentis this the same spider we were looking at a moment ago?
- TeacherIs this the head??
- StudentWhat is the big round part?
- Bugscope Teamthis is kind of disappointing -- yes it is the head
- Studentno its not its a caterpillar
- Studentthank you e1
- Bugscope Teamit is disappointing because there is a lot of slime on the head that obscures its features
- Studentyour welcome e2
- StudentWho (or what) is e1 and e2?
- 9:24 am
- Studentis it dead?
Bugscope Teamyes, all the bugs in the scope are dead right now
- Studentwe are sitting across from you.Duh
- StudentKaty: speak up!
- Studentwhat would happen if thay were alive?
- Bugscope Teama lot of insects, including the caterpillar forms of insects, release slime that is toxic or tastes bad to discourage other insects, or birds, or especially ants, from eating them
- Bugscope Teamit would be hard to pump down the scope to high vacuum if they werent dead, because they are juicy, and even if you did pump it down, the insects would have no air and they would be getting hit with a high energy beam which should kill them
- TeacherOkay, but I am not Katy
- Bugscope Teamthere is a vacuum in the specimen chamber, so the insects would have to close their spiracles and hold their breath, for awhile...
- StudentDo caterpillars have teeth?
Bugscope TeamI believe they have a set of hinged jaws
- Studentkev you are sitting across the room from him too you have a voice!
- Studenthinged jaws?
- Bugscope Teamno insects have what we would think of as teeth, but sometimes the jaws are hardened with minerals such as calcium
- Bugscope Teamtrapjaw ants are said to have harded jaw tips
- Bugscope Teamwhoops, you drove off the edge of the world
- StudentOOF!
- Bugscope Teamhardened jaw tips, that is
- Bugscope Teamyeah Kev
- Studenti had apet caterpiller once. i found it in the bathroom
- StudentWhat are we looking at?
- StudentOFF!!!
- Bugscope Teamdid it grow up into something you recognized?
- Studenttot
- Studenti mean oof!
- 9:29 am
- Studentno it died in infancy
- Bugscope Teamhere is one of its suction cup legs
- Bugscope Teamthis is like Alien, an alien foot
- Student"Tot" means toddlers out toddling
- Studentwe are smart you know, it would have grown into a moth or a butterfly
- Bugscope Teamor like a squid sucker
- StudentWhat is the thing we are looking at now?
- Studentwhat
- Bugscope Teamyeah Cate says it could have been a maggot
- Bugscope Teamscott is mean
- Studentit looks like one
- Studentpbjb
- Bugscope Teamthis is a deflated proleg
- Studenthaha cate good one lol
- Bugscope Teama professional leg
- Studentkev are you learning anything?
- StudentWhat is the big thing in the middle of the image?
- Bugscope Teamthat is the proleg
- Bugscope Teamof the caterpillar
- StudentWhat is a proleg?
Bugscope TeamThey are the little squishy legs on the abdomen of caterpillars. They aren't "really" legs, because insects only have six legs.
- Studentis that all hair
- Bugscope Teamthose are setae
- Bugscope Teamthe hairs are setae
- Studente2 just forgot how to spell hair . e2, i'm a little tierd
- 9:34 am
- StudentWhat are the spike things that are sticking out from the proleg?
- StudentHaha e2
- Studentyeah what is it
- StudentWhy are you laughing at each other, e1 and e2?
- TeacherKaty says that it is illegal to kill a preying mantis in some states
Bugscope TeamI just looked it up: Turns out that's an urban legend and completely false. It has never been illegal to kill a praying mantis in any U.S. state, nor is there any federal protection for mantids. No species of mantid is listed as threatened or endangered in the U.S. There are no fines for killing them.
- Studenthaha kate
- Studentkev, you don't know us! e2 and e1 rock!
- Studentyour not kev your an imposter!
- Studentis that a leg?
- StudentSome people are double-jointed; are some spiders double-jointed?
Bugscope TeamNope, spider and insect legs can only bend so far in one direction. No tricks or dislocating or yoga-induced flexibility
- Teacherkev is driving
- Bugscope Teamthose are called prolegs, as Annie says, because they are insects, and if insects are defined as having six legs then the leg-like things are called prolegs. Sometimes to be an entomologist you have to think like a philosopher.
Bugscope Teamhahah
- 9:39 am
- StudentThank you, Cate.
- StudentWhat is this? Is it part of the skin?
Bugscope Teamthis is part of the compound eye of a fruit fly
- Teacherthis is a fruitfly eye
- Bugscope TeamThere are several requirements for being an insect...having six legs groups the class Hexapoda
- Bugscope TeamSpiders an choose to eject their legs from their bodies if they want -- for example if they sense poison coursing toward their bodies through a leg they can just let it go
- StudentT.I.E.E. just got a new member BB
- Bugscope TeamTIEEBBK
- StudentSpiders can eject their legs? Do they grow them back?
Bugscope TeamSpiders do molt as adults, and so they can usually grow back their legs---so long as there is minimal damage to the tissue at the base of the leg
- Bugscope Teamthere are setae in between the ommatidia, which are the individual parts of the eye
- Studentyescott thats right
- Bugscope Teamthey don't grow them back
- Bugscope Teamuh-oh---I might be wrong.
- Bugscope Teamgood thing Annie is here
- Bugscope Teamshe is being super sweet -- she is right
- StudentZoom out
- Studentwhat are the pointy things?
- StudentIf they don't grow their legs back, how can they survive?
- Bugscope TeamCate says they can molt several times as juveniles but not as adults.
- Bugscope Teamreally...Pete's tarantulas molt all the time
- Bugscope TeamBut (Cate says) the tarantula-like spiders live longer and molt as adults.
- StudentDaddy Long-Legs grow their legs back though, right??
- 9:45 am
- Studentwho pete?
Bugscope TeamPete is my lab mate who has two or three tarantulas
- Bugscope Teamah-hah! Some spiders (like tarantulas) molt throughout their lives. Some do not. We are both right
- Studentwho pete
- Bugscope TeamWhere is Ian?
Bugscope TeamAsleep
- StudentKaty\Kev: can you zoom out so we can see better
- Studentwhos ian
- Bugscope Teamabout DaddyLongLegs, if you look at them up close they are crustacean like
- Studentare you all asleep?
Bugscope TeamNo, Ian, another entomologist, is currently sleeping. SInce it is not 8 am here yet
- StudentHi, Fred
- GuestG'day
- Bugscope Teamthe controls should work now
- Bugscope TeamLooks like the server crashed... Cate had to fit it.
- Studenthi there fred
- Bugscope Teamhere is your ladybug
- StudentKev is back
- Studentyuk!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
- Bugscope Teamthis ladybug looks like Maria Shriver to me.
- 9:50 am
- StudentOH YOU MUST BE TIERD
- Bugscope Teamwait, that didn't make sense. It is 7:50 am here.
- StudentHow many lenses do the compound eyes have?
- Bugscope TeamAnnie is, like, all energy.
- Studente2 is to cant spell
- Bugscope TeamI am not too bad, I still haven't really adapted to pacific time. I am a morning person
- StudentWhat are the large things by the mouth? Are they jaws are pinchers?
- Studenttalk
- Bugscope Teamthere are two sets of palps -- mandibular and maxillary
- Bugscope Teamthe things at the top of the screen that are forked are hinged jaws
- StudentWhat exactly are we looking at right now?
- Bugscope Teamthat help the ladybug manipulate and taste its food, which could be aphids
- StudentDoes anyone know how many lenses the compound eyes have?
Bugscope TeamIt varies between species.
- Bugscope Teamwe are looking into the mouth, as much as possible
- Studentno. do you
- Bugscope Teamit depends on the insect, of course -- there can be thousands of individual ommatidia
- Studenthello, umesh
- Bugscope Teamsome ants have very few ommatidia
- Bugscope TeamFruit flies apparently have 750 per eye
- Bugscope Teamyou could easily count them in many ants
- Bugscope Teamsome ants are blind, too
- Studenti mean alot
- StudentOof
- Studentwhere is scot J?
- 9:55 am
- StudentWho's umesh?
- Studentvery OOF
- Bugscope Teamyou can tell when you look at ants that they use their antennae, primarily, to get information about the Outer world.
- StudentstillOOF
- StudentIt looks like swish cheese\
- Bugscope Teamclick to stop
- Studentwhat?
- Bugscope Teamwhoever is driving
- Studentoofoofoof
- StudentZOOM OUT
- Studentguys hes working on it!
- Studentgoing to a new thing
- Studentsee
- Studenthello, anyone there?
- Bugscope Teamwe might restart the server if we can't get things going...
- StudenttEACHER IS WORKING ON IT
- 10:00 am
- Bugscope Teamthe preset apparently moved and the microscope control is angry
- Studentare you guye taking a nap?
- StudentT.I.E.E. your caps lock is on.
- Bugscope Teamwe will have to sacrifice a grad student to the microscope to get things working again
- Studentnot enymore
- Bugscope TeamOOF now
- Bugscope TeamI am glad I am in CA
- StudentOOF OOF OOF
- Bugscope Teami think it should be working again
- Bugscope Teamit wouldn't have been Annie -- she keeps us, most of us, in line
- Bugscope Teamsorry about that. Our server computer is dying and we are replacing it soon with a mac mini
- StudentWhat is this??
- StudentE2 is with Kev
- Bugscope Teamthis is one of the legs of the mosquito
- Teacherthis is emma singing on to drive the crazy bus.
- Bugscope Teamyou can see the scales
- Studentlooks like a tree
- Bugscope TeamEmma let us know if you need some help.
- Studenta very small tree
- Teacheryeah, we are looking at a mosquito
- Studentright....
- StudentAre these the pads that help the mosquito stick to things?
Bugscope Teamno these are scales that help the mosquito slip out of spiderwebs and out of the mouths of birds
- Teacherthanks scott
- Bugscope Teamthose are wing scales
- Studentreally?
- Bugscope TeamI am not sure if we saw any tenent setae on the mosquito tarsi.
- Bugscope Teampresets 19, 10, 8 are all places where insects have the sticky pads
- 10:05 am
- Teacherwhat are the pointy things?
- StudentT.I.E.B.B.K.A. now!
- Bugscope Teamthe pointy things are spines that are likely sensory
- Teacherokay thanks.
- StudentDriver: Zoom out, please
- Bugscope Teamthe driver grayed out but is back now
- Bugscope Teamwe think they are sensory because they penetrate the cuticle, and thus they likely connect to the nervous system
- StudentEmma OOF!
- Bugscope Teamthese are fruit fly sticky pads
- Bugscope Teamthese are tenent setae, but they are slightly OOF, as Kev says.
- Bugscope Teamlooks like a plant
- Bugscope Teamlooks like here a preset might have moved unless you drove
- Bugscope Teamok we have it back
- Studentis Fred asleep, or dead?
- Teachersorry
- Bugscope Teamhere is where a mosquito bites you, sometimes we see a lancet poking out
- Bugscope Teamyeah this is the tip of the mosquito proboscis
- Bugscope Teamonly female mosquitos bite
- Studentew
- Studentew
- Studentew
- Teacheri thnk i knew that
- Teachere1 is short for emma
- Bugscope Teamwho's e2?
- StudentEve
- 10:11 am
- Teachere2 is eve
- Studente1 move up
- Teachere2 you are a traitor
- Studentthis is Kev
- StudentHow long do mosquitoes live?
- Bugscope Teamthis is jsut a sheath for the lancet, or stylet, that is inside
- Studente1, im just with kev!
- Teachernot too long i dont think
- Bugscope Teamthe lancet is very sharp and has serrated edges like a steak knife
- Studentyup
- Teacherhow dare you!
- Bugscope TeamNot very long--there are some that will overwinter as adults. But during the summer, most mosquitoes will live about 2 weeks max
- Studentha
- Bugscope Teamthe lifespan of mosquitos varies -- some may live only as long as 4 days
- Teacherkev, let my person go!
- Bugscope Teamand as Annie says, some females can overwinter and lay their eggs in the spring
- Studentno way
- Bugscope TeamFred was probably not sleeping. He has other stuff to do and checks in occasionally to see how we are doing.
- Bugscope Teamit's like having the game on, for him
- Studentwhat ire the thingd on the screen part of his legs?
- 10:16 am
- Teacherdeformed!
- Bugscope TeamKev what?
- Studentnever mind
- Bugscope Teamthe legs are lined with scales
- Bugscope Teamthe wings are made of chitin like the body
- Studentwhat is coming from his mouth
- Bugscope Teamcuticle
- Teacherwhat are those round things
- Bugscope Teamthe donuts are where its antennae used to be
- Bugscope Teamthe proboscis projects from the mouth
- Studenthis face is wierd
- StudentWhat are the round this near its eyes
Bugscope Teamthose are where antennae used to be attached
- TeacherOOPS!
- Bugscope Teamthe proboscis is prehensile like a monkey's tail.
- Studentare you looking at this bug right now everyone
- Bugscope Teamit can probe around and find a good place to bite
- StudentThank you Cate, sorry for the typo.
- Bugscope Teamyes Kev.
- Studentis he under a microscope?
- Studentwell duh
- StudentYou would think that the antennae would be very delicate; how do they not get damaged?
Bugscope TeamThey are less delicate when the insect is alive. Parts get brittle when the insect dies
- Student what i mean is is he in your room?
- Bugscope TeamKev it is a girl and she is inside a scanning electron microscope
- Teacherscott i think only spider monkeys have prehensile tails
- Bugscope Teamwe can show you what the chamber looks like now
- Studentoh thank you scott
- Teacherokay
- Bugscope Teamokay like a spider monkey then
- Teachermuch better
- 10:21 am
- Teachercool!
- Studentthis pic is cool
- Bugscope Teamnow you should be able to see the inside of the specimen chamber of the 'scope
- Studentyes
- Bugscope Teamyou can see the sample, on a sort of platter that is 1.75 inches across
- Bugscope Teamthe cone at the top of the image is where the electrons come down the column
- Studentdoes it have to be dark in the room to see the bugs better?
Bugscope TeamWhen we are looking at things in the TEM we have to have it very dark most of the time
- Bugscope Teamand the cage to the right top is the secondary electron detector
- Bugscope TeamI like it to be dark in the room, but not everyone does
- TeacherScott, sorry i know everything about mammals. i couldnt help my self
- Studentok that is interesting
- Bugscope Teamits ok, you can call out scott when ever you know hes wrong. thats how he learns
- Bugscope Teamthe electron beam comes down the column and is moved from side to side by scanning coils
- Studentwhat time is it in CA now, cate
- Bugscope Team8:25am now
Bugscope Teammy time
- Bugscope Teamso the beam moves like a typewriter, sort of, rastering across the sample
- 10:26 am
- Bugscope Teamthe electron beam is considered primary electrons, and when it hits the sample it produces secondary electrons from the sample surface
- Bugscope Teamwhich is coated with gold palladium
- Bugscope Teamlooks like the driver is grayed out. we can hand the controls over to a person in the students section
- Studenthow does katy get back on?
- Studentyes but its ok
- Studentkaty wants controls to go to E1
- Bugscope Teamyou can log back in as Katy (the teacher) again if you like
- Bugscope Teamgot it
- Studentgot what scott?
- Bugscope Teamscott gave e1 control
- StudentI like my typewriter
- StudentHow many different types of misquitoes are there?
Bugscope Teamaccording to a website I was on earlier, there are 140 types.
- StudentOkay, eve is groovin up to take the controls!
- Studenthi y'all! it's e2!
- StudentE2 is goingto drive
- Student140? wow
- Studentdoes anyone like the Beatles?
- Bugscope Teamthat number could be wrong. That was just according to a site I was at
- Studentsorry its taking a little time
- Studentthat was E1
- Studentnot Kev
- 10:31 am
- Bugscope Teamtake your time
- Studentwhat are the dots on the eyes?
Bugscope Teamthe eyes are kind of smooshed, but if the driver wants, she can take the mag up on one of them
- Bugscope TeamI used to like the Beatles, some songs more than others, but if I buy a CD I will not listen to it
- Bugscope TeamAnnie has to log out! I have to go do some research! Have a great rest of the session
- Studenttraitor!
- Bugscope Teamthe tiny dots?
- Studentthat was E1 again
- Bugscope Teambrb
- Studentwhat is brb
- Bugscope Teambe right back
- StudentBe right back
- Studentthanks
- Bugscope Teamyou can increase the mag even more if you want
- Studentthis is cool
- StudentIs there any advantage to having compound eyes??
- StudentE1 is falling asleeZZZZ...
- Studentthat was E!
- StudentImean E1
- Bugscope Teamwhen we do electron microscopy it is easy to forget that the samples we are looking at are frozen in time, and sometimes they are also dehydrated, like now
- Studentpop quiz for cate: can you name all of the kinds of mosquitos?!
Bugscope Teamno way
- 10:36 am
- Studentwhat are the little dots
- Student?
- Bugscope Teamwe used to think the little dots were analogous to rods or cones in human eyes.
- Studentwow! high mag
- StudentKev if i wanted punctuation i would put it in
- StudentWhat are the advantages or disadvantages of having compound eyes?
Bugscope Teamscott is answering it, hold on :)
- Studentsorry
- Studentapoligie accepted
- Studentthanks E1
- Bugscope Teamcompound eyes give an insect an advantage over us in that they may have better peripheral vision
- Studentwho hungry?
- Studentim talking to myself again
- Studenthey!
- Studentthat was E1
- Bugscope Teamthey have many lenses instead of just a couple of big ones, and if some of the ommatidia get dirty there are often enough that it does not matter
- Studentcan flys see color
- Student?
- Studentcan flies see all of the colors we can?
- Studentommatidia?
- Studentwhat T.I.E.E.
- Student?
- Bugscope Teamsome insects can see more colors than we can
- Bugscope Teamommatidia are the eye facets
- Studentwhat about moqutios?
- 10:41 am
- Studentwhat are ommatidia?
Bugscope Teamthey are the individual parts of the compound eye
- Student?
- Studenthello?
- Studentgood by
- Bugscope TeamCate found a site that says that compound eyes have essentially a much faster refresh rate -- they can see faster than we can by far
- Studentthanks
- StudentDriver: can you zoom out so we can look at something different now?
- Bugscope TeamEmma is drivin'
- Studentzoom out
- Studentno, e2 is
- Studentits eve
- StudentZoom out so we're not looking at such minute details
- Studentim sitting
- Studentlookin at a june bug
- StudentOut! Zoom out!
- Studentemma is sitting next to kev
- Studentnow lets look at a july bug :)
- StudentEmma has bad punctuation
- Bugscope Teameach of the ommatidia will get a bit of the "image" and this gets pieced together and made into a "mosaic". Flying insects like mosquitos have very large compound eyes which will give them almost 180 degree view
- Student.
- StudentWhat is that?
- Studentwhat is what
- Student?
- Bugscope Teama "july" june bug
- Studenta June bug
- StudentThanks, Scott
- Studentt thought it was a june bug
- Bugscope Teamyou can see that it has lost the terminal end of one antenna
- Bugscope Teamthis is the head, the club-looking thing is an antenna
- Bugscope Teamit looks much like a june bug
- Studentnow lets seea "may fly"
- Bugscope Teamwe don't have mayflies today
- Studentare you all looking at the exact thing we are looking at?
- 10:46 am
- Bugscope Teamhaha kev, I get it :p
- Bugscope Teamyes we are looking at the beetle -- is that what you see?
- Bugscope Teamdo you think we would be looking at something different?
- Studentwhat is that thing low center?
- Bugscope Teamif not hit refresh
- StudentWhy does it have only one antenna?
Bugscope Teamthe other one broke off. Antennae are easy to break, as well as legs, when insects are dead
- Studenteww what is it!
- Studentno we are looking at a June bug
- Bugscope Teamthe thing between the forelegs we have seen before but I do not know what it is
- Studentthat was E1
- Bugscope TeamE1 it looks like a june bug but it is small
- Bugscope Teamcompared to a june bug
- StudentT.I.E.E. it probably broke off
- Studentexactly what cate said
- Studentwho is kk?
- StudentPan the view so we can see the rest of the insect, plese
- Studenthave you seen the movie "the blue butterfly"? it is all about insects
Bugscope TeamI have never seen it
- Studentwhat is that
- Student?
- 10:52 am
- Bugscope Teamthat was some debris on the tarsus of the beetle
- Bugscope Teamtarsi, or tarsomeres, are the 'forearm' segments
- Bugscope Teamthe debris had at least one scale
- Studentit is really good
- Student.
- StudentWhat is the fan thing we are now looking at?
- Bugscope Teamdoes the movie have real insects in it?
- StudentTHEY DONT KNOW
- Studentyes. iots
- Bugscope Teamnot the Jerry Seinfeld kind with only four legs
- Studenti mean lots
- Bugscope Teamyeah I am sorry I don't know what this is
- StudentNo not like that
- StudentIs kk still here?
- Bugscope Teamwe have seen them and they seem to be sensory but I don't know what its function is
- Bugscope Teamthere is more and more to know...
- Studentis this part of his mouth?
- StudentIf you are still here, speak to us.
- Bugscope TeamE1 this is something that is part of the thorax
- StudentT.I.E.E. i will call you uu!
- Studentcool
- Bugscope TeamWhen Cate is not writing she is looking stuff up.
- 10:57 am
- StudentWhich is the most complex part of the insect? The head, thorax, or the abdomen?
- Studenthahahahahahaha Katy is tooooooooo!
- Bugscope TeamI am not sure we could answer that correctly -- maybe the head
- Bugscope Teamtiny bit OOF
- Bugscope TeamJunebugs are also known as May beetles. odd
- Studentlookin at a butterfly
- StudentEmma and Kev are feeling dead
- StudentZZZZZZZZZZZZZZZZZZZZZZZ
- Studentwhat?
- Bugscope Teamwhen we were looking at this before we put it into the 'scope we could see that it reflects yellow, bluegreen, and blue light, depending on the angle at which you hold it
- Studentkaty just applied the heart starting machine
- Bugscope TeamThis is a long session, and we have only a 1.75-inch stub of things to look at.
- Studentwhat part of the butterfly are we looking at
- StudentThe wings always seem to have veins; why is this?
- Student?
- Studenti pity you
- Studentvains?
- Bugscope Teamthis is a closeup of only a couple of scales
- Bugscope Teamsome of the veins carry hemolymph, which is like blood
- Bugscope Teamthe scales are analogous to feathers on a bird
- Studentbutterflys have scales
- Bugscope Teambut these are like easily detachable scales
- Studentis that what gives them their color?
- Student?
- StudentInsects have exoskeletons, so why would the veins be on the outside?
- Studentgood question!
- Bugscope Teamthey seem to have both pigmented and structural colors
- 11:02 am
- Bugscope Teamthere are no veins on the inside
- Studentwhat do you mean by structural colors
- Studentthis is Katy now btw.
- Bugscope Teamthey have an open circulatory system
- Studentscott you are still a traitor but when my play about the beatle sis famous im sure youll come see it
- StudentI see that it is noon, so we don't want to take up all of your friday. I just want to thank you very much--we had soooo much fun and learned so much!!!
- Bugscope Teamstructural colors are produced by light refraction
- StudentBy, all. Thanks for your good answers.
- Bugscope Teamthanks for all of your great questions
- Studentcan we all access the images using the password 'katy?'
- Bugscope Teamwe love bugscope
- Bugscope Teamyes E1
- Studentthanks for your great answers, guidance, and funny jokes!
- Bugscope Teamlike if you remember records - the black grooves on the record produce colors that are not from pigments
- Studentwhat a great project
- Bugscope Teamjust go to your member page and click on the transcript
- Bugscope TeamThank You!
- StudentThank you all for teaching us about Bugscope we all had a lot of fun! from, T.I.E.E.B.B.K.K.A.!
- StudentGood by. Thanks you!!!
- Studentthose are all of our initials
- Studentbye!
- Studentsee ya!
- Bugscope TeamBye!
- Student;) So long, from sunny western NY!
