From early detection of breast cancer to steering medicine-delivering micro-robots, learn how this cutting-edge technology could open up a new world of possibility when it comes to seeing, tracking and diagnosing disease.

    Hi. Could someone help me? I broke my laptop 20 days ago. I need 100$ for a new laptop immediately. It costs 600$, but I have only 500$. I am a computer engineering student. I have to do many projects. Without laptop I am staying behind the class.

    This is momemtous, groundbreaking, revolutionary! A massive leap in cancer detection, screening tools, cancer monitoring, cardiovascular imaging/detection/screening, saving millions if not billions of future lives. Let’s hope its cheap, accesible and scalable and without side effects – coupled with AI and remote human support it could be a key component of decentralized, personalized diagnosis at home amongst many other use cases

      We live too long as it is. 60-65 is enough time to do whatever one thinks they should do. The carrying capacity of the planet is limited and so should we be.

    what a liar. he tries to claim that photoacoustic imaging can capture brain signaling. He is a complete liar. he literally explained how photoacoustic imaging works, and brain signals would not respond. he’s a disgusting human seeking fame and fortune to inflate his ego.

    We’re so enthralled with wether or not we can do something that we never stop to think if we should. What science calls discovery I call the rape of the natural world.

    Fascinating technology from the 2010s. It does have its promises but its penetration does not match that of an ultrasound, plus need to have studies on the effects of laser in human trials.

    We cured cancer in 2001 but then they realised they would lose billions in cancer research charities. cancer came from the nuke tests. The U.S tested 200 nukes on their own land the moon and even TRIED blowing up the ATMOSPHERE lots of them died from radiation and their wife’s had deformed babies.
