The purple in the center is the cell’s nucleus. Surrounding it are wispy blue and white microtubules and filaments that make up the cell’s cytoskeleton. The cytoskeleton is made from protein structures called microtubules—the wispy threads surrounding the purple DNA-containing nucleus—and filaments of a protein called actin, seen here as the fine blue meshwork in … Read more
The UC Berkeley Nobel laureate who identified how cells transport and secrete proteins answers a few questions. What is the most exciting field of science at the moment? Neuroscience. There is so much that we don’t know about the brain. Do you believe in God? No, I don’t. But I respect others who do, in … Read more
UCLA scientists have developed a cell phone attachment that acts as a microscope and detects pathogens such as E.coli, which contaminates food and drinking water. “The platform is actually a microscope installed on the cell phone, but using some spatial microfluid devices, we converted to a specific sensor of bacteria. We envisioned that such a … Read more
