Bs, shpw it in real time, i've seen how very expensiv3 electron microscopes work, this looks lik3 a very old microscop3 may aswell be cellular debris.

contrast is not so important as 3-d and this can be done by fotostacking, so forget contrast enhancement

DIC makes no sense because oblique illumination gives the same imaging.

I am sceptic-look Thaidomid genetic med, look at Prozac, benzodiasepines side effects. Mother cells failed. Still bio farming, natural diet, sport, art, meditation, joga, acupunture, herbal healing, permaculture, biodiversity, ayurweda is the the best. I beg scientists to know this metods. Permaculture ecosystem biodiversity, natural herb, music healing. Please talk with bio farmers. Learn from them, help them rescue planet- neutralise toxins and waste in trash industry, producing recycle natural materials, clean water and air by producing natural membranes, filters, bacteria fermentation and acids, replacing chemical conservants, 3D food printers-liofilisates, dry herbs, ferment bacteria, maybe vitamines. Dont go into medicine. Replace pesticides. Please. Natural architecture materials-this you can bio design. Natural homes. We need more natural and ethical medicine because it has better results. I was not believe but it is truth. Life organisms is not toys-this is living, intelligent materials-they react, behave, feel. Science must understand this. People drop medicines and get heal with natural diet, sport, changing habits. We need only remove sugar and chemicals from food, environmant, heal addictions, aggression-thats all. Change finance, work, education, social system. Turn towns green with solar and vertical vegetable gardens. Toxic ambition and competition leads science and business. GMO only in labs or house design. We cant allow gmo to natural environmant-wild nature dies. GMO corn to feed animals- they get sick, need eat grass-vit K, we have stroke, heart attacks because animals font eat natural grass, don't see Sun, live in stress and dirt-we throw tones of food, we must design global production. HMO plants are less vitamines, taste, they need pesticides, they are living one season-seeds are useless. Please check farming and soul recovery programs with mushrooms, bacterias. Pesticides kill bees-they was precisely designed-structural analogs, Nobel prize and failed. Killing naturę, mutate kids living near by fields. Biodiversity fields font nerd pesticides. Feromone cathes for bugs, animals on fields- ducs, wild birds eat snales and worms. Its one system. Science and hunters, chemicals ruin this

That's why chagas chronic stage 4 cardiomyopathy kills faster than stage 4 lung cancer. This happens in the heart. Very painful when the cells burst soon after this occurs. Bedbugs are a vector for transmission as well as kissing bugs. 10% of cases get diagnosed, Chagas should be well known by now, love the video!

Surely the best lecture on NGS prep for beginners. Would love to see more lectures from Prod. Chow!

How do you know there are nucleic acids in the sample? Because you were told that them purification technique is real?

He's brainwashed

This is science fiction that creates huge profits for these computer ,manufacturers

SIR COULD YOU PLLZ PROVIDE SOME REFFENCE BOOK FOR FACS ??

Seriously Carolyn, what a GOAT. Lesbian swagger and brain for days

Thanks 👍👍👍

Very interesting work!

It has been 5 years since this video came out. What is the best NGS Machine now and what an approximate price could be?

thank you it helps a lot

It's been a while since I set up Kölher illumination. I taught a class in this when I was younger. That is one beautiful microscope you've got there... much better than anything I've used. But yes, the first step is set it to bright field. (No filters)

Thanks for the explanation Prof

astrolab

I hope one day I lecture on iBiology.

Very informative! Thank you

Why has this video been seen so little? Thesee technologies open the world for possibilities, possibilities that actually might just allow us to continue inhabiting mother earth.

centering the condesor iris is nonesense. The light source field iris is to be centered. The condensor must always be fixed centerd in the main light path to objective and ocular lenses

Really insight full video 👍 Thanks for uploading 😀

Excelente información

Thank you so much!

Un saluto ai king che lo stanno guardando

Here is my train of thought please correct me if I missed or misintepreted any of the information: So epifluroscence uses excitation ligth to excite a sample however it is inefficent (specificlaly for deep tissue sample) because it doesnt focus on one focal point and out of focus ligth blurs otu the sample not allwoign for analysis for a specific point in the tissue. Confocal microscopy is much mroe better due to the pinhole which blocks out out-of-focus light to better analyze a tissue sample however the problem comes in the scattering of the ligth due to deep tissue penetration and since the confocal micrsocopy works with shorter wavelegnths, and as mentioned in the video previously less scattering and absorption occurs at infrared (longer wavelengths). Therefore, two photon microscopy is most opimal for focusing on a specific focal point in a deep tissue sample due to the use of higehr wavelengths leading to less scattering and focsu on one focal point without out of focus light coming in and overall excitation light is longer than confocal and epifluorescence microscopy techniques.

Great video , thanks for the reference

Excellent lecture. we will miss you Joe!

Thank you so much for this introduction of sc-RNA Seq. This video helps me a lot to understand each steps even though I didn't have much of understanding about this field. Thank you again.

experiments and trafficking for developing Nanotechnology and Synthetic biology. The involved scientist have the same mind set like Dr Joseph Mengele had. Many NS scientist moved after worls war II by Operation Paperclip and until today continue their terrible work against humanity!

Great tutorial

For some reasons.. I think we won't find a lot of flatearther or even Trump supporter in this comment section.

Why isn't the upper green ray parallel to the focal plain, as previously explained?

Fantastic video

Dear Dr. David, I'm really excited for your work. Sir, I'm working on synthetic biology approach to increase sesquiterpene on bacterial system. Please suggest me some important things so that i can achieve my desired product in a large scale scale🙏🙏
