At the University of Southern California, Professor Behrokh Khoshnevis has built a colossal 3D printer that can build a house in 24 hours. Khoshnevis's robot comes equipped with a nozzle that spews out concrete and can build a home based on a set computer pattern. The technology, known as Contour Crafting, could completely revolutionize the construction industry. The Contour Crafting system would glide along the rails and lay down cement. Once that part of the process is finished, humans would do the rest of essential tasks like hanging doors and installing windows. Contour Crafting could also reduce the total cost of owning a home. It could also make it easier to repair homes damaged by devastating weather events. While this project is still being tested, Khoshnevis asserts that this won't eliminate jobs in this sector, but actually create more.

Dr. Omid Farokhzad is an Associate Professor at Harvard Medical School and a physician-scientist in the Department of Anesthesiology at Brigham and Women’s Hospital. He received his M.D. and M.A. from Boston University School of Medicine. Dr. Farokhzad directs the Laboratory of Nanomedicine and Biomaterials at BWH, which he established in 2004. He is a faculty member of the Brigham Research Institute Cancer Research Center at BWH.
Over the last decade, a revolution in so-called nanomedicine has spurred the development of drugs intended to act like our own cellular machinery, as well as tiny robots that may help doctors diagnose and treat diseases.
One such innovation is a cancer drug that consists of particles 100 nanometers long. That means you could fit 1,000 of them across the diameter of a human hair, study researcher Dr. Omid Farokhzad said at the World Science Festival.
The particles are coated with waterlike molecules that allow them to travel inside the body without being detected by the immune system, Farokhzad said. Their surfaces contain molecules that provide them with a "GPS" to seek out abnormal cancer cells.
Once they find a cancer cell, the particles stick, and like a Trojan horse, the cancer cells take them inside where they can release medicine that's toxic to the cell, Farokhzad said.
