Hacking sleep: Meet the transhumanists making sleep obsolete

Posted by in categories: health, life extension, neuroscience, transhumanism

Not everyone wants to sleep in. A growing transhumanism community wants to sleep less, and better, and they’re going to great lengths to make it happen.

For those unaware, transhumanism is an intellectual and cultural movement that aims to improve the human condition, to push beyond our biological limitations, largely through technological advancements. They’re particularly focused on extreme longevity. But with treatments for an extended healthy life still works in progress (and playing out on a very long timeline), some transhumanists have turned their attention to sleep.

The average well-rested person sleeps eight hours a day. The average American lives 79 years. That’s a little more than just 50 years being awake. Life is much shorter than you realized — at least if you agree with your typical sleep-hacker that sleeping is wasted downtime.

Roomba advances robot intelligence with a model that can map your house and remember where it’s cleaned

Posted by in categories: habitats, neuroscience, robotics/AI

The future of household robots owes a lot to 19th century American explorers Lewis and Clark.

At least, that’s what iRobot CEO Colin Angle told a crowd of reporters at a press event in New York on Sept. 16, introducing the Roomba 980, iRobot’s newest trashcan-lid-shaped vacuuming robot. It may look like every other Roomba the company has released over the past decade or so, but this one has a new trick: It knows how to map out its surroundings and find its way home.

“Roomba’s mission is to clean, which is not as exciting as Lewis and Clark,” Angle said, “But nonetheless very important.”

DARPA Has Made a Brain Implant That Boosts Your Memory

Posted by in categories: biotech/medical, neuroscience

In what may seem like a Hollywood blockbuster, Defense Advanced Research Projects Agency (DARPA) has developed an implant that goes directly onto the human brain.

The agency wrote in a statement their device is showing promise with improving patient’s memory tests scores. It is “raising hope that such approaches may someday help individuals suffering from memory deficits as a result of traumatic brain injury or other pathologies.”

DARPA’s Restoring Active Memory (RAM) program presented their preliminary findings at the ‘Wait, What? A Future Technology Forum,’ which is also hosted by the agency at St. Louis.

A fast cell sorter shrinks to cell phone size

Posted by in categories: biotech/medical, mobile phones, neuroscience

“The current benchtop cell sorters are too expensive, too un-safe, and too high-maintenance. More importantly, they have very low biocompatibility. The cell-sorting process can reduce cell viability and functions by 30–99 percent for many fragile or sensitive cells such as neurons, stem cells, liver cells and sperm cells. We are developing an acoustic cell sorter that has the potential to address all these problems.”


Researchers describe an acoustic cell sorter capable of the kind of high sorting throughput necessary to compete with commercial fluorescence activated cell sorters.

Edit: some have commented asking about neurons. Please see the article linked above and the following articles for more information. We probably should have tried to clarify the unknowns more in the image itself. Apologies.

Is Quantum Space-Time a Scale-Free Network Like Facebook?

Posted by in categories: neuroscience, quantum physics, space

Researchers from Queen Mary University of London and Karlsruhe Institute of Technology have developed a model that applies ideas from the theory of complex networks, such as the brain or the Internet, to the fundamental quantum geometry of space-time.

The research is published in Scientific Reports with the title “Complex Quantum Network Manifolds in Dimension d > 2 are Scale-Free.” The research paper is freely available online.

“We hope that by applying our understanding of complex networks to one of the fundamental questions in physics we might be able to help explain how discrete quantum spaces emerge,” said author Ginestra Bianconi.

The Imminence of Transhuman Technologies

Posted by in categories: bioengineering, ethics, existential risks, genetics, health, innovation, neuroscience

Progress always seems to ride a slippery slope. Innovations generally bring a plethora of potential benefits and just as many dangers, the obvious and the hidden. Technologies that tamper with our biological constructs is well underway in the neuro- and biotech industries. Historically, innovations in medicine have usually been beneficial on the aggregate.

But these new breakthroughs go beyond preventing and healing pre-existing causes. Transhuman technologies hold the promise of enhancing who we are as individuals and potentially as an entire species, and the decisions surrounding these technologies are far from simple. Dr. Nayef Al-Rodhan, a philosopher, neuroscientist, and director of the Geneva Center for Security Policy, believes we should be acting now to prepare for the inevitable and the unpredictable ramifications.

Framing Human Motivation

Considering our mixed track record as a species in rolling out groundbreaking innovations, discussing and finding potential solutions to many of the hidden dangers, and obvious ones, seems more than reasonable. One of the more puzzling questions is, where do we begin to have a pragmatic conversation on the ethics of these technologies?

There are plenty of theories about what drive human decisions, not least because human morality is infinitely complex and our minds crave frames through which to make sense of chaos. Dr. Al-Rodhan has his own conception of what drives human motivations. He makes meaning using the lens of “5 P’s” – Power, Pride, Profit, Pleasure, and Permanence – which he posits drive human motivations. “This is my view, the foundation of my outlook…this perceived emotion of self interest drives our moral compass.”

Curing Alzheimer’s

Posted by in categories: biotech/medical, genetics, health, life extension, mobile phones, neuroscience, space

Dr Michael Fossel is a PhD and MD heading up telomerase research and therapy and has kindly written a blog article for Bioviva detailing the work both they and his company Telocyte are doing to fight back against Alzheimer’s.


How Alzheimer’s Can Be Prevented and Cured…

Michael Fossel, MD, PhD

As I said in my medical textbook on aging, “If age is a thief, then the greatest treasure we lose is ourselves.” We fear Alzheimer’s not simply because it takes away our health, but because it steals our souls.

You’re not irrational, you’re just quantum probabilistic: Researchers explain human decision-making with physics theory

Posted by in categories: neuroscience, quantum physics

The next time someone accuses you of making an irrational decision, just explain that you’re obeying the laws of quantum physics.

A new trend taking shape in not only uses to explain humans’ (sometimes) paradoxical thinking, but may also help researchers resolve certain contradictions among the results of previous psychological studies.

According to Zheng Joyce Wang and others who try to model our decision-making processes mathematically, the equations and axioms that most closely match human behavior may be ones that are rooted in quantum physics.
