Vision you can’t see: How the brain senses the time of day
by Nicolai Penafigures by Jasmin Joseph-Chazan Toward the end of the 20th century, the intricate biology of how the eye produces visual information was thought to be well understood– a combination of sensors and circuits in the eye extract features of visual scenes. This information is conveyed from the eye to the brain by specialized neurons that physically connect the two structures (Figure 1, blue). … Continue reading Vision you can’t see: How the brain senses the time of day

Liquid-within-liquid compartments: a groundbreaking discovery in biology
by Hannah Blumefigures by Salvador Balkus In some ways, a living cell is like a shoreline, where some creatures build their homes on rocky, solid structures while others live in shifting and dynamic sands. This ecosystem needs both rigid and fluid structures to support life, and similarly, individual cells in our bodies use both structured and fluid compartments to carry out vital functions. The existence … Continue reading Liquid-within-liquid compartments: a groundbreaking discovery in biology

The Making of ChatGPT: From Data to Dialogue
by Shreya Johrifigures by Cynthia Moncada-Reid What if AI could design personalized workout plans, craft tailored travel itineraries, or even compose cover letters for job applications? With the advent of ChatGPT, it can. ChatGPT is an AI-powered chatbot that uses a cutting-edge machine learning architecture called GPT (Generative Pre-trained Transformer) to generate responses that closely resemble those of a human. Developed by OpenAI, ChatGPT is … Continue reading The Making of ChatGPT: From Data to Dialogue

Are microglia the hero or the villain in Alzheimer’s disease?
by Gizem Terzioglufigures by MJ Park Alzheimer’s disease is a progressive neurodegenerative disorder that affects millions of people worldwide, and despite years of research efforts, there is still no cure. However, recent studies have highlighted the crucial roles of microglia, the resident immune cells of our brain, in the development and progression of Alzheimer’s disease. But the question remains: do microglia defend our brain against … Continue reading Are microglia the hero or the villain in Alzheimer’s disease?
