Lucie's book "15 Million Degrees: A Journey to the Centre of the Sun" is available to buy now - https://geni.us/2oB8V

110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system.

Light takes eight minutes to reach Earth from the surface of the Sun. But its journey within the Sun takes hundreds of thousands of years. What is going on in there? What are light and heat? How does the Sun produce them and how on earth did scientists discover this? Since the Royal Institution was founded in 1799 our knowledge of the Sun has changed dramatically and much of the work was carried out at the Ri.

Join Lucie Green for an enlightening talk, taking you from inside the Sun to its surface and to Earth, to discover how the Sun works, how a solar storm can threaten the modern technology that society relies on and more of the latest research in solar physics.

Lucie Green is a Professor of Physics based at the Mullard Space Science Laboratory, UCL’s Department of Space and Climate Physics. She studies activity in the atmosphere of our nearest star, the Sun. In particular, she looks at immense magnetic fields in the Sun’s atmosphere which sporadically erupt into the Solar System.

Lucie is very active in public engagement with science, regularly giving public talks and appearing on TV shows like Sky at Night.

Aquaponics combines two growing methods, aquaculture and hydroponics, to create a self-contained, well-balanced ecosystem. Fish are fed and raised in a tank and as gravity pulls the wastewater through a hydroponic garden, bacteria feed on the waste, breaking it down into essential nutrients for the plants to grow. The system then returns the cleaned water back to the fish reservoir so the process can begin again.

In this episode, Charles Collins shares his backyard aquaponic and hydroponic gardens where he's able to grow tilapia, leafy greens, peppers, herbs and so much more, all in the suburban desert. Together we grow!

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.
