See-through Brains

From Nature Videos

Scientists have come up with a way to make whole brains transparent, so they can be labelled with molecular markers and imaged using a light microscope. The technique, called CLARITY, enabled its creators to produce the detailed 3D visualisations you see in this video. It works in mouse brains and human brains; here the team use it to look into the brain of a 7-year-old boy who had autism.

Nature’s Smallest Factory: The Calvin Cycle

By Cathy Symington at TedEd

A hearty bowl of cereal gives you the energy to start your day, but how exactly did that energy make its way into your bowl? It all begins with photosynthesis, the process that converts the air we breathe into energizing glucose. Cathy Symington details the highly efficient second phase of photosynthesis — called the Calvin cycle — which converts carbon dioxide into sugar with some clever mix-and-match math.

Targeting Cancer Cell Metabolism

From Nature Video

Cancer cells are hungry. To feed their rapid growth and division, their metabolism changes. Moreover, they use sugar (glucose) in a different way to normal cells. This animation, created by Nature Reviews Drug Discovery, explores the key aspects of the altered metabolism in cancer cells and explains how these can be exploited for the development of new anticancer strategies.

How Microbes Make Us Who We Are

Rob Knight Lecture at Ted Talks

Rob Knight is a pioneer in studying human microbes, the community of tiny single-cell organisms living inside our bodies that have a huge β€” and largely unexplored β€” role in our health. β€œThe three pounds of microbes that you carry around with you might be more important than every single gene you carry around in your genome,” he says. Find out why.
