MIT’s Tiny Implant Could Replace Daily Insulin Injections for Type 1 Diabetes

April 1, 2026April 1, 2026 Pooja Kashyap

MIT engineers just cracked a 30-year-old problem, they kept the transplanted insulin-producing cells alive inside the body without suppressing the immune system. This problem has haunted medicine for decades. To understand that, let’s first consider a situation, you wake up, grab your insulin pen, and inject yourself before breakfast. You’ll do this again at lunch, followed by dinner, again before bed. For millions of people living with type 1 diabetes, this four-times-daily ritual is just the price of staying alive.

Scientists Discover Safer Alternative to Opioids for Chronic Pain

March 30, 2026March 30, 2026 Pooja Kashyap

Researchers discover how morphine relieves pain in the brain and create a gene therapy that mimics its effects without addiction risks. A breakthrough that could transform chronic pain treatment. You hit your toe, and right away it feels like the worst pain ever. But the strange thing is, the pain isn’t exactly the same as the actual injury. Scientists say pain works in a weird way, it’s not just about what your body feels. There’s also an emotional part to it, like a sudden fear or discomfort that makes you…

Northwestern Medicine Doctors in Chicago Saved a Patient After Removing Both Lungs

February 2, 2026February 2, 2026 Pooja Kashyap

The man from Missouri should have been dead by spring 2023. By the time a medical helicopter delivered him to Northwestern Memorial Hospital on a rolling bed of tubes and machines, his body was already struggling to survive. What started as a seasonal flu had curdled into a resistant infection that was essentially melting his lungs from the inside.

OCD Isn’t About Needing Certainty, It’s About a Brain That Can’t Update Beliefs

February 1, 2026February 1, 2026 Pooja Kashyap

Each one of us, sometimes or the other has this weird habit or maybe obsession of checking if we’ve locked the front door or not. You check once, locked. Check again, still locked. Third check. Fourth check. By the tenth check, you’re not actually discovering anything new, yet you can’t shake the doubt. For people with obsessive-compulsive disorder, this scenario is almost… daily. These individuals aren’t indecisive because they can’t think clearly. Instead, recent neuroscience research reveals that their brains struggle to update beliefs based on new information. A study…

AI Is Learning to Predict and Control Cell Fate with scDiffEq

January 27, 2026January 27, 2026 Pooja Kashyap

Have you ever realized that at the very beginning, you started out as just one tiny cell. From that single cell, all the different parts of your body, like your brain cells, heart muscles, blood cells, even skin developed. The question is, how does that one original cell somehow “know” what to turn into? How does it decide to become a brain cell or a heart cell, instead of just staying the same?

Microcompartments: A Hidden Layer Inside Our DNA

October 21, 2025October 21, 2025 Pooja Kashyap

For decades, scientists believed that when a cell divides, its genetic material, called the genome, temporarily loses its 3D organization. And it consequently becomes a “blank slate” before rebuilding itself.

Artificial Neurons That Learn Like the Brain: The DRAM–MoS₂ Breakthrough

September 3, 2025September 3, 2025 Pooja Kashyap

I came across some research from Fudan University recently that really caught my attention – Artificial neuron merges DRAM with MoS₂. As the headline suggests, they’ve built an artificial neuron that doesn’t just copy the way brain cells connect to each other, but also how they adjust their own internal behavior.

The Discovery of Hemifusomes Challenges Old Views on Cell Structure

June 27, 2025June 27, 2025 Pooja Kashyap

In a breakthrough discovery, a new thing in cell biology called a hemifusome has come to light. It showed up when researchers used cryo-electron tomography (cryo-ET), it’s one of the ways to take super-detailed 3D images of cells while they’re still in a fairly natural state. Unlike traditional electron microscopy, which involves a lot of processing that can mess with delicate structures, cryo-ET keeps things closer to how they actually are in living cells. It was Dr. Seham Ebrahim and her team who used this method to uncover hemifusomes in…

ComMAND Circuit Enables More Precise Control Of Gene Therapy

April 30, 2025April 30, 2025 Pooja Kashyap

For years, researchers have been trying to fix genetic diseases by simply adding back the missing gene. The idea is pretty straightforward, if a disease is caused by a faulty or missing gene, just give the patient a working copy. But the tricky part has always been figuring out how to control how much of that gene gets used in the body.

Neuroscience Shows Memory Depends on More Than Just Perception

April 22, 2025April 22, 2025 Pooja Kashyap

If you’ve ever tried to remember where you parked your car while also keeping track of your grocery list, you’ve felt the limits of working memory. A new study from researchers at NYU and Ohio State digs into how the brain decides what to hold onto more carefully and most importantly, how it does it.

Infomorphic Neurons: Self-Learning AI Inspired by Biology

March 29, 2025March 29, 2025 Pooja Kashyap

Imagine if artificial neurons could learn like the ones in our brains, adapting, making decisions on their own, and figuring things out without needing a central command. That’s exactly what scientists are working on with a new kind of artificial neuron called infomorphic neurons. Unlike traditional artificial neural networks, these neurons don’t need an external system to guide their learning. Instead, they learn in a self-organized way, just like biological neurons do.

How Your Brain Filters Information: The Science of Excitation and Inhibition

March 10, 2025March 10, 2025 Pooja Kashyap

Neurons in our brain are constantly taking in and distributing information, be it sound, sight or touch, everything is getting processed in the real time. But how exactly does this work? Recent research sheds light on how groups of neurons work together to encode and process information. The study has surfaced some interesting insights about the balance between excitation and inhibition in the brain.

AI’s Potential: Revolutionizing Healthcare

January 14, 2025January 31, 2025 Pooja Kashyap

The healthcare industry is leveraging conversational artificial intelligence to improve patient engagement. These conversational AIs are based on large language models (LLMs), which provides a window to level up patients’ interactions with the health care systems as these framework offers customized and efficient support.

Synthetic Phosphorylation Networks: A Breakthrough in Cell Signaling

January 8, 2025January 23, 2025 Pooja Kashyap
