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.

Join me Thursday October 29th at 2:30PM Eastern time as I welcome to the Mbongi, Psychologist and Africologist, Wade Nobles, PhD. Dr. Nobles is a founding member of the Association of Black Psychologists and former national President (1994-95). He is Professor Emeritus of Africana Studies and Black Psychology at San Francisco State University and the author of over one hundred (100) articles, chapters, research reports and books; the co-author of the seminal article in Black Psychology, Voodoo or IQ: An Introduction to African Psychology. In this conversation we will discuss Black Psychology today, in what areas it has been most successful and other areas needed currently to further permeate, and current and future works in the making. This will be a powerful powerful show that you do not want to miss. So set your reminder, like, and share with friends and colleagues.

Imagine transforming barren and empty landscapes into abundant food forests, layered with mangoes, legumes, garlic, herbs and corn.

SwaYYam in South India is doing just this by using agroforestry and alley cropping to revitalise soils, produce an abundance of crops and educate local farmers.

Agroforestry and alley cropping allow multiple crops to be stacked in one space, with tree crops providing shelter for low-lying plants and holding water in the soil with their roots. Fast growing biomass plants are used as groundcover and then as a mulch to feed the soil. Nitrogen-fixers make nitrogen available in the soil for other plants and a range of crops are grown for year-round food.

Swales and ploughing on the contour work with the land's orientation to maximise water capture. Deep irrigation and pitcher irrigation take water deep to the roots of trees, especially young sapling plantings.

SwaYYAm and their educational centre, Open Shell Farm, enables local farmers to learn regenerative farming methods, helping them create their own sustainable incomes through healthy soils and bountiful harvests.

SwaYYAm is a recipient of the 2020 Permaculture Magazine Prize: https://www.permaculture.co.uk..../articles/2020-perma

Malvikaa from SwaYYam shares the story of the project and some of their techniques in PM108: https://www.permaculture.co.uk/issue/summer-2021

⁣When the Soviet Union collapsed in 1990, Cuba's economy went into a tailspin. With imports of oil cut by more than half – and food by 80 percent – people were desperate. This film tells of the hardships and struggles as well as the community and creativity of the Cuban people during this difficult time. Cubans share how they transitioned from a highly mechanized, industrial agricultural system to one using organic methods of farming and local, urban gardens. It is an unusual look into the Cuban culture during this economic crisis, which they call "The Special Period." The film opens with a short history of Peak Oil, a term for the time in our history when world oil production will reach its all-time peak and begin to decline forever. Cuba, the only country that has faced such a crisis – the massive reduction of fossil fuels – is an example of options and hope.

What do trees talk about? In the Douglas fir forests of Canada, see how trees “talk” to each other by forming underground symbiotic relationships—called mycorrhizae—with fungi to relay stress signals and share resources with one another.
