New atlas reveals the journey of human cells throughout development

All the cells of the body come from the same tiny clump of stem cells and share the same set of genes. But by following different patterns of activating those genes, they quickly embark towards different destinies, becoming tissues as diverse as liver, blood and brain.Tracking this process in humans—who […]

Yale-led project continues probe into biological markers of autism

Five years ago, a Yale-led partnership launched a landmark study to identify the biomarkers, or biological indicators, of autism that could help diagnose, track, and assess treatments in patients. Since then, the Autism Biomarkers Consortium for Clinical Trials has discovered the first two biomarkers for any psychiatric disorder to be accepted into […]

Small molecule, big potential for treating prostate cancer

Prostate cancer growth is often driven by male sex hormones called androgens. Hormone therapy is commonly administered to lower the level of androgens in the body, but relapse is common when the cancer cells develop resistance to these therapies. A multidisciplinary team of cancer researchers led by Angela Koehler, the […]

A DNA-based nanogel for targeted chemotherapy

Current chemotherapy regimens slow cancer progression and save lives, but these powerful drugs affect both healthy and cancerous cells. Now, researchers reporting in ACS’ Nano Letters have designed DNA-based nanogels that only break down and release their chemotherapeutic contents within cancer cells, minimizing the impacts on normal ones and potentially eliminating painful […]

Broadening the Taxonomy of Cellular Senescence in Aging

Cells enter a senescent state constantly throughout life, largely because they have reached the Hayflick limit on replication, but also due to molecular damage, cancerous mutations, injury to tissue, radiation, or other causes. A senescent cell stops replicating, swells in size, and begins to secrete a mix of inflammatory signals, […]
