109 – Bruce Damer on The Origins and Future of Life

Posted by in categories: biological, computing, space travel

Bruce Damer is a living legend and international man of mystery – specifically, the mystery of our cosmos, to which he’s devoted his life to exploring: the origins of life, simulating artificial life in computers, deriving amazing new plans for asteroid mining, and cultivating his ability to receive scientific inspiration from “endotripping” (in which he stimulates his brain’s own release of psychoactive compounds known to increase functional connectivity between brain regions). He’s about to work with Google to adapt his origins of life research to simulated models of the increasingly exciting hot springs origin hypothesis he’s been working on with Dave Deamer of UC Santa Cruz for the last several years. And he’s been traveling around the world experimenting with thermal pools, getting extremely close to actually creating new living systems in situ as evidence of their model. Not to mention his talks with numerous national and private space agencies to take the S.H.E.P.H.E.R.D. asteroid mining scheme into space to kickstart the division and reproduction of our biosphere among/between the stars…

As oceans warm, microbes could pump more CO2 back into air, study warns

Posted by in categories: biological, climatology, sustainability

The world’s oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year—a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their bodies. When plankton die, they sink, taking the carbon with them. Some part of this organic rain will end up locked into the deep ocean, insulated from the atmosphere for centuries or more. But what the ocean takes, the ocean also gives back. Before many of the remains get very far, they are consumed by aerobic bacteria. And, just like us, those bacteria respire by taking in oxygen and expelling carbon dioxide. Much of that regenerated CO2 thus ends up back in the air.

A new study suggests that CO2 regeneration may become faster in many regions of the world as the oceans warm with changing climate. This, in turn, may reduce the deep oceans’ ability to keep locked up. The study shows that in many cases, bacteria are consuming more plankton at shallower depths than previously believed, and that the conditions under which they do this will spread as water temperatures rise. The study was published this week in the journal Proceedings of the National Academy of Sciences.

“The results are telling us that warming will cause faster recycling of carbon in many areas, and that means less carbon will reach the and get stored there,” said study coauthor Robert Anderson, an oceanographer at Columbia University’s Lamont-Doherty Earth Observatory.

Scientists Unveil a ‘Brain Decoder’ That Turns Neural Activity Into Speech

Posted by in categories: biological, information science, neuroscience

The spoken word is a powerful tool, but not all of us have the ability to use it, either due to biology or circumstances. In such cases, technology can bridge the gap — and now that gap is looking shorter than ever, with a new algorithm that turns messages meant for your muscles into legible sounds.

Converting the complex mix of information sent from the brain to the orchestra of body parts required to transform a puff of air into meaningful sound is by no means a simple feat.

Microbes may act as gatekeepers of Earth’s Deep Carbon

Posted by in categories: biological, climatology, sustainability

Two years ago a team of scientists visited Costa Rica’s subduction zone, where the ocean floor sinks beneath the continent and volcanoes tower above the surface. They wanted to find out if microbes can affect the cycle of carbon moving from Earth’s surface into the deep interior. According to their new study in Nature, the answer is affirmatively—yes they can.

This groundbreaking study shows that microbes consume and—crucially—help trap a small amount of sinking carbon in this zone. This finding has important implications for understanding Earth’s fundamental processes and for revealing how nature can potentially help mitigate climate change.

The Origins of Us: Evolutionary Emergence and The Omega Point Cosmology — A New Book That Makes You Question The Nature of Reality but Provides You with Surprising Answers | Press Release

Posted by in categories: cosmology, evolution, neuroscience, physics

Ecstadelic Media Group releases a new non-fiction book The Origins of Us: Evolutionary Emergence and The Omega Point Cosmology by Alex M. Vikoulov as a Kindle ebook (Press Release, San Francisco, CA, USA, April 22, 2019 01.00 PM PST)

The Science and Philosophy of Information book series is adapted for general audience and based on the previously published grand volume titled The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution” by digital philosopher Alex Vikoulov on the ultimate nature of reality, consciousness, the physics of time, and philosophy of mind. In this book one of the series, the author addresses some of the most flaming questions in science and philosophy: Where do we come from? What are the origins of us? What is our role in the grand scheme of things?

# 1 Hot New Release” in Amazon charts in Cosmology and Evolution, the book starts with a story that happened almost exactly 400 years ago that has had a tremendous “butterfly” effect on us modern humans.

Researchers develop new variant of Maxwell’s demon at nanoscale

Posted by in categories: biological, nanotechnology, quantum physics

Maxwell’s demon is a machine proposed by James Clerk Maxwell in 1897. The hypothetical machine would use thermal fluctuations to obtain energy, apparently violating the second principle of thermodynamics. Now, researchers at the University of Barcelona have presented the first theoretical and experimental solution of a continuous version of Maxwell’s demon in a single molecule system. The results, published in the journal Nature Physics, have applications in other fields, such as biological and quantum systems.

“Despite its simplicity and the large amount of work in the field, this new variant of the classical Maxwell demon has remained unexplored until now,” notes F\xE8lix Ritort, professor from the Department of Fundamental Physics of the UB. “In this study, we introduced a system able to extract large amounts of work arbitrarily per cycle through repeated measurements of the state of a system.”
