Why Research Matters?

What if we could map the cellular conversations happening inside a tumor?
In this episode of Why Research Matters, Varunika Goyal speaks with Dr. Hamim Zafar, Associate Professor at IIT Kanpur, about computational biology, spatial biology, and the future of cancer research. Dr. Zafar explains how his lab uses machine learning and genomics to understand tumor evolution, cellular heterogeneity, and the interactions between cancer cells and their surrounding microenvironment.
A key focus of the conversation is Renoir, a computational tool developed by his lab that helps decode cell-to-cell communication in spatial transcriptomic data. Renoir goes beyond identifying ligand–receptor interactions by examining the downstream genes affected by these signals.

In this episode of Why Research Matters, Dr. Varunika Goyal speaks with Dr. Oliver Bower, a developmental biologist and gene-editing researcher, about human embryonic development, CRISPR-Cas9, base editing, prime editing, preimplantation genetic testing, and the future of reproductive medicine.
Dr. Bower explains what happens during the first seven days of human embryonic development and why this stage is important for genetic research. The conversation also explores how inherited diseases such as sickle cell disease, beta thalassemia, cystic fibrosis, Huntington’s disease, and muscular dystrophy can be identified.
They discuss the differences between CRISPR-Cas9, base editing, and prime editing, as well as the risks of embryo gene editing, germline editing, designer babies, informed consent, regulation, and the controversial case of He Jiankui.
This episode offers an accessible introduction to the science, possibilities, and ethical challenges of editing the human genome.

How does a single cell become an embryo? Developmental biologist Dr. Özge Özgüç explains why early life is not controlled by genes alone. Cells also use physical forces to divide, move, fold, attach, and organize into an embryo. This clip explores the hidden mechanics behind development, microscopy, stem cell models, IVF research, and why biology is also physics.
