      @Liam Jarrett This is one of the most unhinged and misinformed takes I have probably ever seen. I don't think for a second that you could justify this silly argument. The premise behind it sets up the most unfathomable slippery slope one could even imagine. Why do you even get up in the morning or do anything at all that could advance your life or others? Following your thought process, does doing that also make you selfish, reckless and contributing to overpopulation to some degree?

      It wasnt invented at all in stanford, they just innovated on an ancient microscope design known as a leeuwenhoek single sphere lens microscope. There is a massive difference between inventing something and innovating upon sonething, Antonie Van Leeuwenhoek deserves all the credit for the original design as well as over 100 microscope patents that HE INVENTED from 1640 - 1723 and is recognized as the father of microscopy and microbiology.

    To the people wondering, 'There aren't 51 billion people on Earth.' He meant that more than 100 billion people LIVED on Earth, not LIVING. Half of them have been diagnosed with malaria. But if this was invented back then, it would SAVE 51 billion lives, hence the title. I hope people see this so they don't get confused with the amount of population with the number of inhabitants that the Earth HAD.

      0:35 the video states exactly that. 100 billion people have lived on earth. More than half of them died of malaria.
      Therefore about 51 billion people died of malaria during the history of humanity.

      @Zenmasterme I read a lot of condescension in these comments and especially from you. Ignoring simple facts such as that the pricing on their site is for private sale. This would be one of the largest contributing factors to how they recover R&D costs and generate profit for future endeavours. Do you really think that this is the price they would charge to supply a NGO or charity?
      They aren't aiming to "diagnose or differentiate the many strains of Malaria" but to provide a proof of concept of what's achievable on a minimal budget.They have more than achieved their goal.
      You may have worked in laboratories throughout the world but you clearly lack effective intelligence and emotional maturity.

      D 3 жыл бұрын +18

      @Zenmasterme cute, your attempt to overwhelm the discussion with specifics doesnt change the what they are saying. You are getting ahead and beyond what they are talking about. This is triage and you are talking treatment. Two different stages of the same issue. Odldy enough you gave up on the cost issue you were so hard set on? Is that because you can't argue the facts? Credentials mean nothing when you are close minded and opposed to the idea that someone may have outdone you.
      They are coming up with solutions that educate and help. You are profiteering, saying that only the "expert" should talk and only the "expert" can help.

    Feeling nostalgic as that spinning thing is called chakkarghinni here in India. It is a common toy in rural areas.
    Mind blowing and super ingenious to create such an awesome device using simple materials.
    Cheers to these scientists from India, who still at heart felt the need for such device at far end rural places and created such masterpiece !

      It's more along the lines of for 68 cents you can detect an illness in one person that over the history of time killed 51 billions lives. disregarding the fact that knowing your sick doesn't cure it, and that the cost is per patient, this is still friggig great.
