For all we understand about the universe, 96% of what’s out there still has scientists in the dark. Astronomical observations have established that familiar matter—atoms—accounts for only 4% of the weight of the cosmos. The rest—dark matter and dark energy—is invisible to our telescopes. But what really is this dark stuff? How do we know it’s there? And what does it do? From the formation of galaxies to the farthest reaches of space, it appears that darkness rules. Without dark matter and dark energy, the universe today and in the far future would be a completely different place. We were joined by leading researchers who smash together particles, dive into underground mines, and explore the edges of the known universe in search of clues to nature’s dark side.

How far would you go to improve your focus, memory, or even learning ability? Would you be willing to strap on headgear that delivers electrical shocks to targeted areas of your brain? You may soon have that option. It’s called trans-cranial direct current stimulation, and it’s currently being tested on soldiers and used by gamers, students, and others looking for a cognitive edge. But questions linger: does it work? What are potential long-term effects? And how should it be regulated?

Following on from the multiple award-winning "Limits of Perception" and "Time Limits", this is the third and final part of the trilogy of films that explores the limits of our everyday perceptions and beyond, showing that the world is a far more remarkable place than most of us ever realise. Humans are visual creatures -- sight is our main sense. Yet our eyes often deceive us in peculiar ways. There is far more to light than meets the eye. This fascinating documentary explores the human's visible spectrum of light and ventures even further into territories we cannot sense by ourselves without technical equipment: from coloured light to gamma rays, that could destroy all life on Earth, as well as radio waves, without which our modern society would be impossible. The film also follows the great pioneers, from Newton and Einstein, to Herschel and Roentgen, whose genius uncovered the marvels of the electro-magnetic spectrum and took us far beyond the limits of light.

Recently, Lola Eniola-Adefeso and colleagues published a commentary in Cell describing the systemic inequities in research funding through the NIH, which have created a barrier to the success of Black scientists. By funding applications from Black investigators at approximately half the rate of similarly trained white investigators, the NIH has created a burden on Black scientists that leads some to abandon academia, and slows or blocks promotion of others, limiting their scientific achievement and career trajectory.

In this webinar, Eniola-Adefeso shares her personal journey through academia and the set of recommendations offered in the article for NIH policies to eliminate the funding disparity, as well as action items for fellow scientists, the private sector, and academia to overcome the racism that is endemic in the sciences.

0:01 Introduction by Pat Stayton
7:08 Lola Eniola-Adefeso Begins Presentation
1:15:50 Q&A

This event was moderated by Pat Stayton, PhD, Director, Molecular Engineering and Sciences Institute, University of Washington

About the Speaker:
Lola Eniola-Adefeso is the University Diversity and Social Transformation Professor in the Department of Chemical Engineering at the University of Michigan, as well as a Miller Scholar and Vice Chair for Graduate Studies at the University of Michigan. She is also the co-founder of Asalyxa Bio, which is developing an innate immune cell targeting platform to treat inflammatory diseases.

This event was held as part of our series Amplified: Race and Reality in STEM on February 22, 2021. Amplified: Race and Reality in STEM aims to give a national platform to speakers to have candid conversations around race and diversity in the STEM fields. Launched in 2020 as part of Gladstone’s commitment to diversity, equity, and inclusion, this series is hosted in partnership with Georgia Tech, the Molecular Engineering & Sciences Institute at University of Washington, and The University of Texas at Austin. We hope these discussions spark change throughout the sciences.
