This mini-lecture introduces the future battery. The Faculty of Applied Science and Textiles (FAST) and the Institute of Textiles & Clothing (ITC) organized the mini-lecture series for more than three years. The lectures aim to enrich students' knowledge in creative perspectives and arouse their interest in Sciences, Fashion and Textiles. In view of the unpredictable development of the COVID-19 pandemic, the upcoming mini-lecture Series will be switched from face-to-face mode to online mode.

What if we looked at Parkinson's as an neurological electrical problem? Brain researcher Eleftheria Pissadaki and her team study dopamine neurons, the neurons that selectively die during Parkinson's. They discovered that the bigger a neuron is, the more vulnerable it becomes because it simply requires more energy. This new insight is reframing the disease -- and by "finding the fuse box for each neuron" and figuring out how much energy it needs, may help us neuroprotect our brain cells.

Sue Desmond-Hellmann is using precision public health -- an approach that incorporates big data, consumer monitoring, gene sequencing and other innovative tools -- to solve the world's most difficult medical problems. It's already helped cut HIV transmission from mothers to babies by nearly half in sub-Saharan Africa, and now it's being used to address alarming infant mortality rates all over the world. The goal: to save lives by bringing the right interventions to the right populations at the right time.

Dr. Bustamante begins his talk by explaining why one would wish to study biochemical reactions at the level of a single molecule. He explains that many processes within the cell are carried out by very few molecules. By studying single molecules, it is possible to obtain details about the mechanism of a reaction that cannot be ascertained by studying a population of molecules. Bustamante goes on to describe the technique of optical tweezers and how it can be used to manipulate single molecules. His lab has successfully used this method to follow DNA transcription one molecule at a time and RNA translation one codon at a time. In both cases, single molecule studies provided detailed information about complex biochemical processes.
