T cells are built to detect and destroy cancer cells with surgical precision—recognition, lock-on, and apoptosis. But tumors evolve ways to evade them. Modern immunotherapy is about tipping that balance back.

A fruit fly brain, mapped in full. 🧠 What looks like abstract art is a complete network of neural wiring and vasculature. Because it’s so small, scientists can trace nearly every connection, linking circuits directly to behavior and uncovering rules that scale to human brains.

Not all TMS is the same. Studies show standard targeting can miss by >1 cm, and optimized placement can differ by ~14 mm. Small changes = different circuits. Same protocol, different dose. In any other field, that’s a dosing problem.

Microplastics are no longer just in the environment. New data shows they’re in 100% of human brains studied, with higher concentrations linked to tumor growth.

This image shows hippocampal pyramidal neurons—the cells that support memory and break down in Alzheimer’s disease. As these neurons degenerate, the circuits behind learning and recall begin to collapse.

A study in Cerebral Cortex analyzed brain scans from 365 individuals (ages 5–24) and found localized differences along white-matter pathways involved in language, social behavior, and sensory processing. Autism may reflect distributed wiring differences across brain networks.

⚔️ Natural killer (NK) cells are part of the immune system’s frontline defense. Unlike other immune cells, they don’t need prior exposure to recognize a threat. In this microscope footage, an NK cell identifies and destroys a cancer cell, releasing molecules that trigger its death

Stroke doesn’t just damage the brain, it may reshape it. A new study finds the injured hemisphere can appear biologically “older,” while regions in the opposite hemisphere look “younger.” A possible sign the brain is reorganizing to compensate for lost function. 🧠

3D light sheet fluorescence microscopy is giving researchers a new view of Alzheimer’s disease. By imaging entire intact mouse brains, scientists can map amyloid plaques across the brain and see how they align with the vascular network. Credit to the team at Gubra!

Glutamatergic neurons are the brain’s primary drivers of excitation, fueling learning, memory, and cognition through synaptic plasticity. When disrupted, they’re linked to depression, schizophrenia, Alzheimer’s, and epilepsy. Understanding them = understanding how the brain adapts.

Alzheimer’s doesn’t look the same in every brain. New research shows early tau buildup varies across racial and ethnic groups. Will this change the way we approach treatment?

🧠 Cancer + the nervous system = a deeply complex network. AI is emerging as the tool to decode these nonlinear interactions—revealing how tumors behave, adapt, and evolve. Not replacing biology—just finally making sense of it.

Neurons reaching out to form connections. These tiny extensions search for nearby cells, and when they meet, a synapse can form — the foundation of how the brain communicates. 🧠

How Stress Shapes Organ Development Mechanical strain doesn’t just deform tissue, it can fracture it. In embryos and zebrafish hearts, controlled cracks guide cavity formation and build trabeculae.

A single CRISPR injection removed an HIV-like virus from infected primates by cutting viral DNA directly out of the genome. Instead of lifelong suppression, gene editing may allow permanent removal of HIV from viral reservoirs, a major step toward a cure.

New BMJ review on psychedelic medicine shows the strongest evidence for psilocybin in depression and MDMA in PTSD. The science points to neuroplasticity, brain network changes, and psychological flexibility. The real challenge now is scalability and real-world implementation.
