Astronomers Just Found Some of The Most Massive Black Holes Discovered in Our Universe
Posted by Genevieve Klien in categories: cosmology, evolution, physics
A study on dozens of galaxies within several billion light years of our own has revealed black holes that far exceed our expectations on just how big these monsters can grow.
The discovery not only helps us better understand the evolution of our Universe’s building blocks, it leaves us with a new intriguing question – just how do black holes like these get to be so incredibly massive?
By now, the collapsed cores of massive stars known as black holes need no introduction. We’ve heard about their cosmic crashes rippling space-time, watched them belch, and expect to capture the closest look yet at their nature very soon.

We are already Artificial Intelligence

By Eliott Edge
“It is possible for a computer to become conscious. Basically, we are that. We are data, computation, memory. So we are conscious computers in a sense.”
—Tom Campbell, NASA
If the universe is a computer simulation, virtual reality, or video game, then a few unusual conditions seem to necessarily fall out from that reading. One is what we call consciousness, the mind, is actually something like an artificial intelligence. If the universe is a computer simulation, we are all likely one form of AI or another. In fact, we might come from the same computer that is creating this simulated universe to begin with. If so then it stands to reason that we are virtual characters and virtual minds in a virtual universe.

Why I Spent A Week Without My Phone … — By Gigi Falk | Thrive Global
Posted by Odette Bohr Dienel in categories: computing, evolution, fun
“My phone habits are, I’d like to think, better than most. I seldom take my phone out in company and it’s a rare site to see me scrolling through social media. But when I’m walking to or from work, standing in an elevator, or eating by myself, I’ll often be checking emails, texting friends, or reading articles.”

Why Do We Age? The Disposable Soma Theory Answers the Riddle
Posted by Brady Hartman in categories: evolution, life extension
Summary: Why Do We Age? Scientists answer the question with the latest evolutionary theory of aging, the disposable soma theory, which supports the longevity benefits of calorie restriction. With commentary by leading geroscientist, Tom Kirkwood. [This article first appeared on the website LongevityFacts.com. Author: Brady Hartman. ]
The process of aging, or growing old, presents an apparent contradiction to people who believe in Darwin’s theory of evolution. Aging increases the vulnerability of an organism, which ultimately leads to its death. How could evolution favor a process that gradually increases mortality and decreases the ability to reproduce?
Leading scientists have found an answer to this puzzling contradiction and offer us new theories to explain why we age and die using evolutionary theory – the idea that aging confers an evolutionary advantage.

How bacteria turbocharged their motors
Posted by Klaus Baldauf in categories: evolution, habitats, nanotechnology
Using detailed 3D images, researchers have shown how bacteria have evolved molecular motors of different powers to optimize their swimming.
The discovery, by a team from Imperial College London, provides insights into evolution at the molecular scale.
Bacteria use molecular motors just tens of nanometres wide to spin a tail (or ‘flagellum’) that pushes them through their habitat. Like human-made motors, the structure of these nanoscale machines determines their power and the bacteria’s swimming ability.

The Quest for Immortality, Rebooted
Posted by Derick Lee in categories: biotech/medical, evolution, life extension, neuroscience, singularity, transhumanism, virtual reality
Shermer’s journey into the present-day search for human domination over death and society’s ills introduces readers to all forms of what he calls “techno-optimism,” meaning the belief that technological progress means an end to death — or, at the very least, to aging and social decay. There are the cryonicists who want to freeze us, and those who want simply to freeze our brains, with all their neural connections and associated memories (the connectome). The transhumanists want to enhance us so thoroughly — through means both natural and artificial — that we become godlike, “taking control of evolution and transforming the species into something stronger, faster, sexier, healthier and with vastly superior cognitive abilities the likes of which we mere mortals cannot conceive”; the Omega Point theorists think we will all one day be brought back to life in a virtual reality. Believers in “the singularity” contend that it is possible to upload the human brain to a server without losing the essence of what makes you you. And, of course, there are those who try to cure us of aging, so that our bodies and minds will cease to deteriorate and our life spans will increase ad infinitum. Shermer visits each of these and other utopian theories with detail and considered analysis, drawing readers along increasingly unrealistic (or are they?) possibilities for our future evolution. It’s a journey as boggling as it is engrossing.
In “Heavens on Earth,” Michael Shermer explores the lengths to which mankind will go to ensure our souls’ survival beyond existence on this mortal coil.

Has human evolution reached its peak?
Posted by Philip Raymond in categories: aging, evolution, genetics, life extension
According to a French physiologist, humans have reached the peak of our height, lifespan and physical fitness.
I suspect that from our vantage point (a narrow snapshot of human evolution), we lack sufficient data to arrive this sweeping conclusion. Nevertheless, mainstream media is taking this research seriously.

The Ten Best Science Books of 2017
Posted by Derick Lee in categories: biotech/medical, evolution, science
But the best science and tech writing goes one step further. With delight and mystery—and sans unnecessary jargon and technical details—this genre can help us better understand some of the world’s most complex and abstract concepts, from gravitational waves (Gravity’s Kiss) to Darwinian evolution (The Evolution of Beauty) to antibiotic resistance (Big Chicken). Each of these remarkable tomes from 2017 does just that, shining a light on the hidden connections and invisible forces that shape the world around us. In doing so, they make our experience of that world that much richer.
