Optogenetics: Using Light to Control Cells and Possibly Treat Blindness
Introduction Optogenetics—the technique of genetically modifying cells so they respond to light—has transformed neuroscience research. By inserting genes for light-sensitive proteins (like channelrhodopsins) into specific neurons, scientists can turn electrical activity “on or off” with pulses of light. Beyond basic...

Is Type 1 Diabetes Curable? Progress on Beta Cell Regeneration
Introduction Type 1 diabetes (T1D) is an autoimmune disorder where the body’s immune system attacks and destroys the insulin-producing beta cells in the pancreas. Without adequate insulin, cells cannot properly absorb glucose, leading to high blood sugar and long-term health...

Bionic Pancreas: Tech and Biology Merging to Cure Diabetes
Introduction Diabetes affects millions globally, requiring strict blood sugar management to avoid complications. Traditional care involves manual insulin injections or pumps, guided by fingerstick glucose checks or continuous glucose monitors (CGMs). Despite these tools, daily life remains burdensome. Now, cutting-edge...
