The chemical origin of life on earth | Marcel Eleveld | TEDxAlkmaar

How did life originate? This is one of the most fundamental questions of humankind and the central question of my PhD research. In my talk I will guide you through what we know so far about simple molecules becoming complex living systems and I will share my view on how we can further unravel the mystery of the origin of life of earth.

This Molecule Could Explain the Origin of Life

Hydrogen cyanide is a molecule that appears to be at the heart of the creation of life. To create it, scientists need a burst of energy the equivalent of an endless lightning storm.

Where is the Origin of Life on Earth?

To answer the iconic question “Are We Alone?”, scientists around the world are also attempting to understand the origin of life. There are many pieces to the puzzle of how life began and many ways to put them together into a big picture. Some of the pieces are firmly established by the laws of chemistry and physics. Others are conjectures about what Earth was like four billion years ago, based on extrapolations of what we know from observing Earth today. However, there are still major gaps in our knowledge and these are necessarily filled in by best guesses.

We invited talented scientists to discuss their different opinions about the origin of life and the site of life’s origin. Most of them will agree that liquid water was necessary, but if we had a time machine and went back in time, would we find life first in a hydrothermal submarine setting in sea water or a fresh water site associated with emerging land masses?

Biologist David Deamer, a Research Professor of Biomolecular Engineering at the University of California, Santa Cruz, and multi-disciplinary scientist Bruce Damer, Associate Researcher in the Department of Biomolecular Engineering at UC Santa Cruz, will describe their most recent work, which infers that hydrothermal pools are the most plausible site for the origin of life. Both biologists have been collaborating since 2016 on a full conception of the Terrestrial Origin of Life Hypothesis.

Lynn Rothschild, Senior Scientist at NASA’s Ames Research Center and Adjunct Professor of Molecular Biology, Cell Biology, and Biochemistry at Brown University, who is an astrobiologist/ synthetic biologist specializing in molecular approaches to evolution, particularly in microbes and the application of synthetic biology to NASA's missions, will provide an evolutionary biologist’s perspective on the subject.

Origins of Life: Chemical Origins - Chemistry and the Origins of Life

These videos are from the ComplexityExplorer.org course 'Origins of Life. This course aims to push the field of Origins of Life research forward by bringing new and synthetic thinking to the question of how life emerged from an abiotic world.

This course begins by examining the chemical, geological, physical, and biological principles that give us insight into origins of life research. We look at the chemical and geological environment of early Earth from the perspective of likely environments for life to originate.

Taking a look at modern life we ask what it can tell us about the origin of life by winding the clock backwards. We explore what elements of modern life are absolutely essential for life, and ask what is arbitrary? We ponder how life arose from the huge chemical space and what this early 'living chemistry' may have looked like.

We examine phenomena, that may seem particularly life like, but are in fact likely to arise given physical dynamics alone. We analyze what physical concepts and laws bound the possibilities for life and its formation.

Insights gained from modern evolutionary theory will be applied to proto-life. Once life emerges, we consider how living systems impact the geosphere and evolve complexity.

The study of Origins of Life is highly interdisciplinary - touching on concepts and principles from earth science, biology, chemistry, and physics. With this we hope that the course can bring students interested in a broad range of fields to explore how life originated.

The course will make use of basic algebra, chemistry, and biology but potentially difficult topics will be reviewed, and help is available in the course discussion forum and instructor email. There will be pointers to additional resources for those who want to dig deeper.

This course is Complexity Explorer's first Frontiers Course. A Frontiers Course gives students a tour of an active interdisciplinary research area.The goals of a Frontiers Course are to share the excitement and uncertainty of a scientific area, inspire curiosity, and possibly draw new people into the research community who can help this research area take shape!

Origins of Life Systems Chemistry, John Sutherland, Cambridge

Origins of Life Systems Chemistry

By reconciling previously conflicting views about the origin of life – in which one or other cellular subsystem precedes, and then ‘invents’ the others – we suggested a new modus operandi for its study. Guided by this, we uncovered a cyanosulfidic protometabolism which uses UV light and the stoichiometric reducing power of hydrogen sulfide to convert hydrogen cyanide, and a couple of other prebiotic feedstock molecules which can be derived therefrom, into nucleic acid, peptide and lipid building blocks. We are now considering the transition of systems from the inanimate to the animate state through intermediate stages of partial ‘aliveness’, and recent progress in the elaboration of building blocks into larger (oligomeric) molecules and systems in this context will also be described.

The Origins of Life Speaker Series explores the conditions and circumstances that led to the diversity of life on Earth. The interdisciplinary series will connect the formation of planets, the evolution of early Earth, and the complex chemistry and delivery of the fundamental organic molecules that serve as the building blocks of early life, and how they can establish complex, self-replicating systems of cells and genetic material.

Can chemistry solve the origin of life? Perry Marshall, Denis Noble and Lee Cronin

Can chemistry crack the mystery of the origin of life? Justin is joined by Perry Marshall who has established the $10m Evolution 2.0 Prize for anyone who can show a natural explanation for life.

Lee Cronin of Glasgow University is confident that his experimental research could win it. Denis Noble also joins the conversation as they discuss the nature of life and whether current evolutionary theory can account for its origins.

Abiogenesis 101, The Origin of Life Introduction

Today, we learn about the Origin of Life on Earth. How did life emerge from the inanimate world? Scientists have a good explanation of how abiogenesis could have occurred. We know life emerged spontaneously by chemical processes that we understand, but we don't know exactly what happened 3.5 billion years ago in the primordial soup.

How did life begin? This Abiogenesis video will give you a good explanation of how many scientists think the primordial soup could have lead to the origin of life on earth. Please watch if you are interested where LUCA, the last universal cellular ancestor, came from. We also discuss the RNA world hypothesis.

I also speculate on the chance of life occurring. Are we alone in the universe? I don't think so.

The Future of Representation | Khalid Ouaziz | TEDxAlkmaar

Growing up as an ambitious Moroccan kid born in Alkmaar was an experience filled with perseverance, doubt, learning to deal with my Moroccan and Dutch identity and to be confident when teachers said ‘Music won’t bring you any success!’. I’ve had the pleasure of international hits, touring the world, and publish my world views with an annual magazine that showcases greatness in diversity in the Netherlands. I would love to share my ideas on the importance of role models and inclusiveness.
