- Bugscope Teamhello nancy
- Bugscope TeamHi Nancy
- Bugscope Teamwhere are you from?
- Guesthi, tucson az
- Bugscope Teamhola juan
- Bugscope TeamThings are pretty quiet right this moment, we're waiting for a live connection from Columbia. Ah, they just arrived
- Guesthi..a little late
- Bugscope TeamHola!
- Bugscope TeamHi MenDuGo!
- Guesthi how are you_
- Bugscope TeamGood!
- Bugscope TeamJuan!
- Teacherhi again
- Bugscope TeamHola, bienvenidos a bugscope
- Bugscope TeamBienvenidos.
- GuestThanks!
- TeacherGracias.
- Bugscope Teamhola marval
- Bugscope Teamhola marval
- Studenthello!!!!!
- Bugscope TeamYou can see on the screen where the microscope has been imaging for a long time today.
- Bugscope TeamWe burned a mark on this eye.
- Teacherthe guys are just gettin logged..give us a minute
- Studenthello
- Bugscope Teamno problemo
- Guestwhat objects we are observing
- Bugscope TeamJuan you have control, and if things do not seem to work for you let us know. And take your time.
- Studenthi Cate!!
- Bugscope Teamthis image is a close up of a compund eye
- Bugscope Teamcompound eye i mean
- Studentholaa
- Studentwhat are we watching?
- Bugscope TeamMenDuGo this is a bugscope connection with a class in Colombia.
- Bugscope Teamthese are images from an ESEM (environmental scanning electron microscope)
- Bugscope Teamthis is the compound eye of an insect, I think a true bug, but I don't remember right now. Someone would have to take the magnification down a little
- GuestI know Scott I am a student of Juan
- 11:26 am
- Bugscope Teamdescachaladrada, that is a long name, but once you get the hang of it it's nice!
- Studentduarte
- Bugscope Teamme llamo alejandro
- Bugscope TeamCool!]
- Studentand now??
- Bugscope TeamOops.
- Studentsanti how are you
- Bugscope TeamSo MenDuGo totally cool.
- Bugscope Teama limb is covering part of the head
- TeacherHi!!!
- Bugscope Teamhola juan
- Bugscope TeamWe are concerned that there will be a big lag time when you actually drive the 'scope. So let us know if we need to drive or can help in any way from here.
- Bugscope Teamvery nice to see you again, you should have control now
- Bugscope TeamJuan has control of the 'scope now.
- Bugscope TeamThis is a 'true' bug.
- Bugscope Teamyes, juan, if your lag is bad, then please let us know, we can drive for you, and show you interesting things, and tell you about them.
- Teacherwhat is the reason why som students are getting logged out automatically??
Bugscope Teamwe do not know of anything that would do that on our end
- Bugscope Teamif any of you have questions, please just ask
- Studentjuan lets go and do it
- Bugscope TeamThere are two true bugs on the sample stage and some other insects as well.
- GuestHi again, can you tell me what type of insect it is?
Bugscope TeamThis looks like what we call a plant bug
Bugscope Teamthis is a true bug. True bugs have piercing mouthparts.
- Bugscope TeamBut it happens sometimes.
- Bugscope TeamThis is a hemipteran.
- Studentwhat type of insect is that
- Student what is this?
- Guesthoo cool
- StudentHi!!
- Studentwhats that?
- Bugscope Teamjuan, maybe the limited network bandwidth is causing some students to be logged out or disconnected. maybe double up students on a computer will help?
- StudentA bug
- Bugscope TeamThey have piercing mouthparts and a particular orientation of their wings that characterize them.
- Teacherwhat degree do you guys have?
Bugscope TeamI have a masters degree in entomology and I am working on my PhD
- Bugscope Teamof their wings/elytra.
- Guestwhat is the common name of insect_
- Bugscope Teamvarious degrees
- StudentWhats the name of the insect we are looking at?
Bugscope TeamI believe this is a plant bug, an insect in the family Miridae.
- Studentwhat is the real size of the byg
- Bugscope Teami have a master degree in music composition
- Studentwhat is the real size of the insect
Bugscope Teamwell, the insects are anywhere from millimeters to centimeters, if you zoom out, you can see the whole insects, and then look at the scale bar in the lower left of the image for scale
- Bugscope TeamI have a bachelor degree in Physics
- Bugscope Teamyou can get an idea of the size from the scale bar on the lower left side of the screen.
- 11:31 am
- Studentwhat is the common name of that bug
Bugscope TeamI think it is a plant bug
- StudentWhat is the real size of the insect?
- Bugscope Teamnot sure of the common name
- Studentwhich is the scientific name?
Bugscope TeamI am not sure of the species...I study beetles--which are hard enough!
- StudentWhat have you studied?
Bugscope TeamI study the evolution of pheromone communication in longhorned beetles.
- Bugscope Teamit is probably a little more than a cm long
- Bugscope TeamI have a degree in English and Biology and have been doing electron microscopy since I got out of college 25 years ago.
- Guestlol
- Bugscope Teamplease try clicking on one of the presets when you are ready. We are anxious to see how much control you have.
- Studentwith what kind of electronmicroscope are we watching this insect?
- Bugscope TeamSo far it looks good.
- Bugscope Teamif you want to go to a different insect/object, you can click on a preset in the lower right corner
- Bugscope TeamThis is a field emission scanning electron microscope.
- Bugscope Teamthis is an environmental scanning electron microscope (ESEM), here is a picture of it: http://www.itg.uiuc.edu/ms/equipment/microscopes/esem/
- Teacherare we going to see any other insects?
- Bugscope Teamit is actually an environmental scanning electron microscope, but we are using it in HiVac mode now.
- Studentwhat kind of special characteristics it has?
Bugscope Teamcheck out this webpage for information on this scope: http://www.itg.uiuc.edu/ms/equipment/microscopes/esem/
- GuestOk, I have some quiestions: What is the common name of the Hemipteran?
Bugscope TeamThe common name for insects in the order Hemiptera is true bugs
- Bugscope Teamif you want to see another insect have Juan click on one of the presets, to the right of this chat box on his computer.
- Bugscope Teamif that does not work let us know
- Bugscope Teamcool looks like it is working
- Teacherok..im changing the view to another insect
- Bugscope Teamjuan is controlling the scope now. we can give control to any other student at any time. but onle one person at a time
- 11:36 am
- Bugscope Teamyou can see the eyes take up most of the area of the head
- StudentDo you have a general picture of the microscope?
Bugscope Teamyes, there is a picture of it on this website: http://www.itg.uiuc.edu/ms/equipment/microscopes/esem/
- Studentwhat is the name of this insect
Bugscope Teamthis is just a small moth. I dont know the particular species
Bugscope TeamThis is a moth
- Bugscope Teamthe proboscis (its mouthpart) is curled up in the middle of the head
- Studentwhat is this?
- Bugscope Teamthis microscope has backscattered electron detectors, energy-dispersive spectroscopy (elemental analysis), a Peltier heating/cooling stage, electrical feedthroughs, two hot stages, etc.
- StudentA fly
- Bugscope Teamyou can see now that this is several mm long.
- Bugscope Teamthis is a moth -- you can tell by the scales
- Bugscope Teama moth is a couple of millimeters, i think, or maybe bigger?
- StudentWhy the image is white and black and not colored?
Bugscope Teamthese images are from an electron microscope, and the images are gathered NOT with light, but with electrons, so it's a totally different way of accessing an image and thus we only see shares of grey, not colors
- Bugscope Teamwe are very happy to be connecting with Colombia. This is the first time we have connected with the southern hemisphere.
- TeacherCan I change the position of the image? (dispace the cebter?)
Bugscope TeamYes, go ahead and try the Click to Center tool in the controls on the right
- Studentwhat are that little things in the mouth
Bugscope TeamThose are scales that have rubbed off of the moth's body. Moths and many butterflies are completely covered with scales.
- Bugscope Teamthe image is produced by collecting secondary electrons from a sample that has been coated with gold-palladium.
- Teacherwe're happy to paticipate on this project to...\
- Teachertoo..
- Bugscope Teamoops we did connect with Australia, but never South America.
- StudentOK, thanks
- Bugscope Teamyes, you are doing great juan! keep going!
- Studentthank you annie
- Bugscope Teamyou are welcome!
- Bugscope Teamthe samples are in a vacuum chamber, and we beam electrons at them.
- TeacherI still can't find a way to move the picture
- Bugscope Teamjuan - try click to center
- Studentannie what did you study
- Studenthow much eyes do this insect has?
- Bugscope Teamjuan - there is probably too much lag to "click to drive", so use "click to center" instead
- Studentcan you give us specific characteristics of this bug please
- Teacherok click to drive is the option..got it
- Studenthow many guest do you have per day?
Bugscope TeamWe are a research facility, so students at the University here come to use it all day. We typically do 2-3 remote bugscope sessions a week though
- 11:42 am
- Bugscope Teamclick to drive will be slow because of lag
- Bugscope Teamthe electron beam passes continuously across the surface of the sample, and as it does it produces secondary electrons that are pulled toward a photomultiplier tube -- a PMT -- that gives us the assembled image.
- Bugscope Teamtry click to center instead
- Studentannie, what did you study and what specializations do you have
Bugscope TeamI am a PhD student in entomology. I got my master's degree in 2005 and will hopefully finish my PhD next spring. I study pheromones in longhorned beetles.
- Bugscope Team92 um is 92 microns, or 92 micrometers
- Bugscope Teamthe u should be a Greek mu.
- Studentannie what did you study
Bugscope TeamAnnie has been, and is studying Entomology -- a.k.a. the study of insects
- Teacherok..i'll let it in click to center...
- Bugscope Teamfor reference, a bacillus is normally 2 microns in length
- Bugscope Teamjuan - you can also click on a preset (lower right side) and then the scope will move to that preset
- Bugscope Teamwith click to center, you should be able to click somewhere on the image and the software will make that the center of the screen
- StudentIn which part of the insect are we?
Bugscope Teamthis is the head
- StudentAnnieeeeeee
Bugscope Team;)
- StudentWhat is the high zoom the microscope can raise?
Bugscope Teamthe highest possible, is 600,000x, but with insects, you can't see much past 20,000x or 30,000x
- Studentheyy how much eyes do this insect has?
Bugscope Teamthe eye is called a compound eye, which is made up of individual facets, or ommatidia
- Bugscope Teamcediel - this is the eye of a moth, a compound eye
- Bugscope Teammost of these are airdried and coated with 7 or 8 nm of gold-palladium to make them conductive.
- Bugscope Teamthis is the head of the moth
- Bugscope Teamand we are looking at a few ommatidia -- the facets of the compound eye
- Bugscope TeamI am going to try to remember to collect lots of interesting insects for bugscope when I am out in the field this summer.
- Bugscope Teamyou can see from the scalebar that we are at a fairly high magnification now, for insects
- Studentscott what did you study and what are your specializations
- Bugscope Teamnow you can see the scalebar says 720 nanometers
- Bugscope Teamwow, 77,000x, nice
- Studentwhat are the basic advantages of the microscope youre using?
Bugscope TeamLight microscopes are fundamentally limited in their resolving power (resolution) by the wavelength of the light you use, about 300-700nm. Electron microscopes use much smaller particles and so they can magnify about 100x greater than light microscopes. Also, because the electrons don't penetrate the surface, you get exceptional surface detail even on things that appear transparent
- Bugscope Team720 nanometers is approximately the width of the wavelength of red light, so this detail would be impossible to observe using a light microscope
- 11:47 am
- Bugscope Teamwow, 155,000x!
- Bugscope TeamI worked with amphibian pigment cells for 5 years, mostly doing TEM. Then I was at a dental school for 10 years and looked at teeth, and bacteria, bone, implants, lots of stuff.
- StudentHow many zoom are we using at this momment?
Bugscope Teamcheck out the number in the upper right, magnify, it says 155,000x, now 77,000x
- Teacherwhich insect has been the most difficult to analyze??
- Bugscope Teamnormally when we want to go to very high mag we at closer to the sample and the image will look better
- StudentAt which temperature does the microscope need to be, and what is its size?
Bugscope TeamThe microscope is generally at room temperature, and itself is about the size of a mini refridgerator, but fills a room with supporting equipment
- Bugscope Teamfor bugscope we have the sample at a long working distance
- Bugscope Teamthe microscope is now at room temperature
- Studentwhat are the basic advantages of the microscope youre using?
- Studentwhat parts of the bug are we looking at
Bugscope TeamWe are looking at the eye
- Bugscope Teamwhen we work in wet mode sometimes we work at 4 C
- TeacherHow can you control the intensity of the beam (and what effect does it have over the image?)?
Bugscope TeamThe shape of the electron beam can be controlled using magnetic fields, because *moving* charged particles feel a force from magnetic fields. This allows us to focus the electron beam on the sample and improve resolution.
Bugscope TeamEssentially, we're using electromagnets to shape the electron beam the way a light microscope uses glass lenses to shape an optical beam. We don't often vary the intensity of the beam, a.k.a. the spot size, except in extreme situations where we want to generate a lot of X-rays for atomic composition analysis
- Bugscope Teamthe microscope uses liquid nitrogen
Bugscope TeamThe liquid nitrogen is used to cool an extra X-ray detector
- Bugscope Teamthis microscope will allow us to work without making the sample conductive
- Bugscope Teamscott is always scaring me by pouring liquid nitrogen by my feet
- Studentwhat parts of the bug can we see now
Bugscope TeamWe are still looking at the eye of the moth
- Bugscope TeamDescach this is still just a few eye facets
- Teachernice question juan
- StudentHow much time do we still have?
- Bugscope TeamNow we are looking at a fly mouth
- Bugscope Teamnow we see the proboscis of a fruit fly
- Studentwhat is this?
- Guestwhat is that
- Studentwhat is the maximun size of a the sample you use in a microscope?
- 11:52 am
- Bugscope Teamthe stage is 50 mm across
- Guestmosca de la fruta
- Bugscope Teamthat's right mosca de la fruta
- Guestyes i knoe annie
- Bugscope Teamthis is part of the feeding apparatus that normally does not look good because (normally) the samples are air-dried
- Studentbye! thanks for all
- Guestthank you good bye
- Bugscope Teambut Cate critical point dried this sample for oyu
- Bugscope Teamyou
- Studentthank you annie, scott, chasfo, chas , cate and alex!!!
- StudentOK thak you very much
- Teacherok..this is the first group..they're leaving now..thank you so much...theres another group coming

- Bugscope Teamyou are coming to the US in december?
- Bugscope Teamnice Alex
- Guestyes
- Bugscope Teamcool!
- Teacherget me some nice girls
- Studenton june
- Studentto LA
- Bugscope Teamwell we are in Illinois, south of Chicag
- Studentmy cousin is Pamela Rueda, she is a Biologist
- Bugscope TeamChicago
- Bugscope TeamHey Cool.
- Studentand his housband discovered a new specie of fish
- Bugscope Teamyou dont want to go to Illinois, especially in the summer. It's all humid and sticky :p
- Bugscope Teamcomo se dice June? Juno?
- 11:57 am
- Teacherbye thank u for everything!!!!!!!
- Bugscope Teamjunio
- StudentJunio
- Bugscope TeamOops Junio got it, gracias
- StudentOK bye and thank you very much for all
- Student]have a nice day
- Bugscope Teamgracias!
- Bugscope Teambuenas dias
- Bugscope TeamYou too Thank You!
- Bugscope TeamSo Juan you seem to be able to control the 'scope well.
- Bugscope Teamjuan you did well driving, do you have any questions?
- TeacherI'm organizing the other group..so far so good..:)
- Bugscope Teamcool
- Bugscope Teamuna hora mas
- Bugscope Teamyou are doing a great job controlling the scope.
- Bugscope Teamjuan, keep in mind, all the images and chat are saved on your member webpage: http://bugscope.beckman.uiuc.edu/members/2008-023
- Bugscope Teamuh oh
- Bugscope Teamhe''ll be back
- Bugscope Teamhola JD
- Bugscope Teamhola Kiko
- Bugscope Teamlike the hasta la vista dude
- Bugscope Teamhola terrozco
- Bugscope Teamhola juan!
- Teacherhola caracoles
- Teacherhola tema
- 12:02 pm
- Teacherhola alex
- Teacherteam
- Studenthello
- Bugscope Teamdo you say equipo for team?
- Teacherque tamano tiene el insecto?
- Studentyes
- Teacherque tamaÑo tiene esa mosca
- Bugscope Teamtamano?
- Bugscope Teamthis is a fruit fly
- Studentjulicar
- Bugscope Teamwhat ---- has the insect?
- Teacherwhat size?
- Studenthola chahin
- Bugscope Teammosca de la fruta
- Bugscope Teamthis is less than a cm long
- Teacheris it female o male?
Bugscope Teamthis is female
- Bugscope Teamnotice the scale bar in the lower left of the image
- Teacherwe have an issue here...i have logged in again under the nick Juan_Carlos
- Teacherwhat size is the fruit fly?
Bugscope Teamit is less than a centimeter big
- Bugscope Teamit is okay juan, we know who you are as long as you log in as teacher
- Teacheri am mer nerd
- Bugscope TeamJuan because you could not use your name again? that happens to us
- Teacherthe nicks are all messed up...is that normal?
- Teacheri love to study
- Bugscope TeamJuan this is a nerd paradise, here where we work
- Studenthow much zoom does the microscope has?
- Teacherwhat kind of insect is that
- Bugscope Teamfruit fly
- Bugscope Teamthis is a fruit fly
- Bugscope Teamit eats the fungi that is made on rotting fruit
- Teacherwhat did you study?
- Bugscope Teamwe can go over 800,000x but for publishable images usually no more than 200,000x
- Bugscope TeamI studied English and Biology.
- Bugscope Teami studied music composition in college
- Studenthi scott
- Bugscope Teami studies Physics
- Studenthi scott
- Bugscope TeamI quizzed out of Spanish but it was long ago
- TeacherI want to see another insect!!!
Bugscope Teamgo ahead and click on a preset to move to another insect
- Bugscope Teamit is black and white because we are not using light -- we are using electrons
- 12:07 pm
- StudentHMM..DO YOU GUYS LIKE YOUR JOBS??
- Bugscope TeamHola SanManu
- Bugscope Teamwe like what we do
- Studentwhy is in black and white
Bugscope Teaminstead of using light to gather the image, the ESEM uses electrons, so the image is gathered in degrees of grey, not color
- Teacheris there another machine better to watch insects?
- Bugscope Teami love my job. i am always learning something new
- Bugscope Teamalex - all yours, I can't type fast enough
- Teacherhow are you out there
- Bugscope Teamwe are privileged to be able to use electron microscopes all day
- Teacherwhatb is the real size of the insect? i really love this
- Teacherhow are the eyes of the fly?
- Bugscope Teambecause we are using electrons rather than light, we do not see colors
- Studentbut... are you always doing this?
- Bugscope Teamthe electron beam is smaller than the wavelengths of visible light
- Bugscope Teamwe dont always do bugscope. We have around 3 sessions of bugscope a week
- Studenthow is the structure of the fly
- Studentanimal
- Bugscope Teamthis is a microscopy laboratory and we train people to use all kinds of microscopes
- Studentscott: how does an electron microscope work?
- Studentwhat is the structure?
- Teacherwhy if you studied music are you doibg this alex?
Bugscope Teambecause being a computer person pays the bills much better than music does
- Bugscope Teamwhen we see eyes that are broken, sometimes, it appears that they are actually crystalline like glass lenses
- Bugscope Teamthe compound eyes have individual parts called ommatidia and they each get a part of an image of whats around them and send it back to their brain
- Bugscope Teamthe samples are in a vacuum, and we beam primary electrons at the samples, with a great deal of control
- Bugscope Teamfocus!
- Studenthow is liquid nitrogen useful during the process?
Bugscope Teamliquid nitrogen is used to cool down the EDAX, which is a separate device that can sense chemical composition of what is in the scope
- Bugscope Teamthe ocelli are found on top of their head so we don't always see them. They act like a compass
- Bugscope Teamwhat we get back are secondary electrons that give us the images we see
- Teacher do you work with something else???????
Bugscope Teamyes, some researchers look at compounds, or metals, or bone scaffolds, etc.
- 12:12 pm
- Bugscope Teamliquid nitrogen is not used for the ESEM directly
- Bugscope Teamin between each of the ommatidia are little spikey hairs called setae (see-tee)
- Bugscope Teamwe use liquid nitrogen with this microscope just to keep the field effect transistor cooll enough so that the signal to noise will be high
- StudentWhat function does those hairs have?
Bugscope Teamthe hairs, called setae, are used for sensory, chemosensory or mechanosensory. the setae connect to nerves underneath the exoskeleton
- Bugscope Teamthe hairs on the eyes help the fruit fly judge windspeed
- Teacherwhich size is the butterfly?
Bugscope Teamwe didn't put the whole butterfly on the aluminum stub, we only cut off a piece of the wing because the scales are interesting to look at
- Studenthi, again
- Studentmelo te amo
- Bugscope Teamas Cate said we are supposed to call the hairs setae
- Bugscope Teamhola again ManDuGo
- Studentwhich part of the insect are we?
Bugscope Teamthis is just a part of a monarch butterfly wing
- Teacherscott what did study?
- Bugscope Teamthe stuff on the bottom is silver paint
- Bugscope Teamit helps ground the electrons
- Bugscope Teamthis as Cate says is just a portion of the wing
- Teacherthe hairs in the eyes help for what???
Bugscope Teamthe setae in the eyes are for sensing wind movement and air speed, they help the fly to respond very quickly to things in its path
- Studentwhat kind of buttlerfly is
Bugscope Teamthis is a part of the wing of a monarch butterfly
- Teacherare you happy with your work scot?
- Bugscope Teamthe hairs on the fruit fly eyes help it judge wind speed/direction
- Teacherscott what did you study?
Bugscope Teamhe studied biology and english
- Teacheryou are all butterflies!!
- 12:17 pm
- Bugscope Teammariposas
- Bugscope Teamd'oh
- Bugscope Teamjuan, are you logged in as "wonder boy" or is that someone else?
- Teacherare there other machines to analize insects?
- Teacherwhat does this butterfly eat??
Bugscope Teamit eats milkweed, which is often poisonous to many other animals
- Bugscope TeamI was afraid I would become an English teacher so I added biology
- Teacherthat is someone else..sorry for that comment...\
- Bugscope Teamah, no problem juan, we were all kids ourselves one day ;)
- Bugscope Teamyou could use a light microscope, of which there are many types, to study insects
- Bugscope Teamsince the butterfly likes to eat from milkweed, other predators won't eat it because it is poisonous from eating it as well
- Studentso tell me, what are we exactly trying to see?
- Bugscope Teamwe have several cool microscopes in our lab: electron, atomic force, confocal, reflected, etc.
- Studenthow fast does the butterfly is able to f
- Bugscope Teamhere we see the scales of the Monarch butterfly, but we are at low mag...
- Studenthey i have a question, do we have this kind of technology in colombia?
- Bugscope Teamthe colors of the scales are apparently not real colors but structural colors
- Studentwhat is vacuum used for during the process?
- Bugscope Teamit is very likely you have several of these microscopes in Colombia
- Teacherwhat is this?
- Teacherwhich is your function?
- 12:22 pm
- Bugscope Teamthe vacuum ensures that the electrons can fly unimpeded through space
- Bugscope Teamor smaller
- Bugscope Teamthe scalebar is in the lower left so you can see right now is is saying 1mm
- Studentwas it dificult to upload this sistem to internet??
- Bugscope Teamelectron microscopes are specialized CRTs.
- Bugscope Teamwe wrote the first control software over 9 years ago
- Teacherwhen did you start this virtual system and why?
- Teacherwhere does it lives?
- Studentwhat does CRTs means?
- Bugscope TeamChas rewrote it recently
- Studentwhat is CRTs?
Bugscope TeamCRT means cathode ray tube
- Bugscope Teamcrt is a cathode ray tube, which is what a TV is
- Studentwhich is the fuction of the hair in the bugs?
Bugscope Teamthe hairs are called setae (see-tee), and they are connected to nerves underneath the exoskeleton, they help the insect to sense its environment
- Studentis this the mos powerful microscope ever made?
- Bugscope Teambut in this case the cathode is controlled so that the electron beam can be collimated and directed,using scanning coils, in a pattern at the sample
- Bugscope Teamthere are now more powerful microscopes, but this is a particularly good one
- Bugscope Teamsetae (hairs) can be chemosensory or mechanosensory, so they can help the insects sense things in many cool ways
- Studenthow many people are you able to have conected at the same time???
Bugscope Teambugscope can take 25-30 people maximum, more than that and the lag is so bad. it also depends on your network connection, if you are fast, then we can take more
- Studenthow mucvh does a microscope like this cost
- Studenthow much is one of those microscopes?
- Bugscope Teamwhen you have a more powerful microscope, as in better resolution, you have to also give up something, like the size of the sample or the depth of field
- Bugscope Teamthis cost about $600,000 in 1998
- Bugscope Teamwe don'e to have anymore than 20, it tends to create a big lag sometimes as well as a lot of confusion when they are all typing at once
- 12:27 pm
- Bugscope Teambut our dollar is not what it used to be!
- Teacherwhat is the capacity of this microscope?? the maximun zoom?
- Bugscope Teamwe can actually magnify over 800,000x
- Studentare the pictures shown by the electronic microscope all in black and white?
Bugscope Teamyes, it is all black and white because the image is gathered with electrons, not light, but we can false color the images afterward, using elemental analysis of the image
- Bugscope Teambut for useful publishable images no more than about 200,000x
- Studentso, is that the bugs mouth?
- Bugscope Teamthe images are black and white because we are not using light to collect the images -- we are using electrons
- Bugscope Teamin the middle of the image looks to be a palp, which helps the insect taste or eat food
- Bugscope Teamelectrons are smaller than the wavelengths of visble light (400 to 700 nm)
- Studentbyer vhsdf\
