From a bee’s hexagonal honeycomb to the elliptical paths of planets, symmetry has long been recognized as a vital quality of nature. Einstein saw symmetry hidden in the fabric of space and time. The brilliant Emmy Noether proved that symmetry is the mathematical flower of deeply rooted physical law. And today’s theorists are pursuing an even more exotic symmetry that, mathematically speaking, could be nature’s final fundamental symmetry: supersymmetry. Join some of the world’s preeminent scientists to explore the core role symmetry plays in our unraveling of nature’s deepest secrets—and catch a glimpse of profoundly important symmetries that may be awaiting us just over the horizon.

This is one of several films made at Imperial College London in conjunction with ICI. The entire film, except for a short end sequence, was shot in the laboratory of Professor Eric Laithwaite at Imperial College London. This is one of many examples demonstrating electromagnetic forces and in particular the linear induction motor for which Eric Laithwaite was famous. Many of what he called his 'toys' are seen, these are models that help demonstrate the concepts and forces of electromagnetic induction etc.
This was currently the best transfer from 16mm film that we had of this unique engineer in his 'work place', but for a better quality version please now go here: https://youtu.be/CmKF72CPR0s

Wastewater treatment is an essential part of modern infrastructure, and it's function is simpler than you might think. Take a closer look at how wastewater treatment plants work and how your waste gets turned back into clean water that you can drink.

TRANSCRIPT:
Plants are amazing. They create energy from sunlight and they use this energy to create what we use for our food, fuel and fibre, and this takes us on a journey deep into the inner world of a plant cell.

Plant cells collect sunlight and use it to convert water and carbon dioxide into sugar. This process is called photosynthesis. Photosynthesis happens inside the many green chloroplasts found around a plant cell.

The movement of water, carbon dioxide and other molecules like nitrogen, sugars and salts are vital for good plant health.

But how do water and other solutes get into the cell? Aquaporins are here to help. Aquaporins are tiny protein channels that are created in plant cells. They facilitate diffusion, the movement of important solutes, across cell membranes.
Aquaporins can be found in different membranes of the cell.

Water, carbon dioxide, and more is moved across these membranes, via aquaporin channels, as required.

Let’s see how plant cells create aquaporins when needed.

Proteins like aquaporins are coded for by genes. This is a sequence of information within a cell’s DNA. A message, called RNA, is first created from a gene through a process called transcription.

Messages move out of the nucleus to the ribosome. Here, the RNA message is “read” to create an aquaporin protein. This process of building a protein from an RNA message is called translation.

Aquaporins, like all proteins in a cell, have a unique structure. An aquaporin’s main function is to act as a channel that sits in a membrane. The aquaporin’s structure reflects this role.

Through research we can come to understand how aquaporins work, and how they work best. We can apply this knowledge to produce higher yielding crop plants by maximising their photosynthesis, improving their salt tolerance and enhancing their ability to survive challenging environmental conditions. And more efficient and resilient crops will ensure a secure food future.

Fertile land is scarce in Egypt. All of life depends on water from the Nile River. 85 million Eyptians are settled along its banks. The rest of the country is desert. Egyptian and German scientists have now found a way of cultivating forests in the desert sand.

It looks like a fata morgana. But the forests in the Egyptian desert are real. They're watered with processed sewage. 24 such forests have sprung up across the country over the past eight years. The sewage is rich in nutrients and fuels the growth of plants like mahagony, eucalyptus and sisal.
