Dynamics of Telomere Rejuvenation during Chemical Induction to Pluripotent Stem Cells

Posted by in categories: biotech/medical, life extension

Chemically induced pluripotent stem cells (CiPSCs) may provide an alternative and attractive source for stem cell-based therapy. Sufficient telomere lengths are critical for unlimited self-renewal and genomic stability of pluripotent stem cells. Dynamics and mechanisms of telomere reprogramming of CiPSCs remain elusive. We show that CiPSCs acquire telomere lengthening with increasing passages after clonal formation. Both telomerase activity and recombination-based mechanisms are involved in the telomere elongation. Telomere lengths strongly indicate the degree of reprogramming, pluripotency, and differentiation capacity of CiPSCs. Nevertheless, telomere damage and shortening occur at a late stage of lengthy induction, limiting CiPSC formation. We find that histone crotonylation induced by crotonic acid can activate two-cell genes, including Zscan4; maintain telomeres; and promote CiPSC generation. Crotonylation decreases the abundance of heterochromatic H3K9me3 and HP1α at subtelomeres and Zscan4 loci. Taken together, telomere rejuvenation links to reprogramming and pluripotency of CiPSCs. Crotonylation facilitates telomere maintenance and enhances chemically induced reprogramming to pluripotency.

Milestone claimed as experimental nuclear reactor reaches temperature of the Sun

Posted by in category: nuclear energy

One of the possible pathways to limitless and clean energy can be found in hollow, doughnut-shaped chambers known as tokamak nuclear fusion reactors. A relatively new player on the scene, a UK company called Tokamak Energy, is claiming a new milestone in the area after heating its ST40 device to 15 million degrees Celsius, similar to temperatures found at the center of the Sun.

Volkswagen tests quantum computing in battery research

Posted by in categories: business, information science, internet, quantum physics, robotics/AI

For the first time, Volkswagen experts have succeeded in simulating industrially relevant molecules using a quantum computer. This is especially important for the development of high-performance electric vehicle batteries. The experts have successfully simulated molecules such as lithium-hydrogen and carbon chains. Now they are working on more complex chemical compounds. In the long term, they want to simulate the chemical structure of a complete electric vehicle battery on a quantum computer. Their objective is to develop a “tailor-made battery”, a configurable chemical blueprint that is ready for production. Volkswagen is presenting its research work connected with quantum computing at the CEBIT technology show (Hanover, June 12–15).

Martin Hofmann, CIO of the Volkswagen Group, says: “We are focusing on the modernization of IT systems throughout the Group. The objective is to intensify the digitalization of work processes – to make them simpler, more secure and more efficient and to support new business models. This is why we are combining our core task with the introduction of specific key technologies for Volkswagen. These include the Internet of Things and artificial intelligence, as well as quantum computing.”

The objective is a “tailor-made battery”, a configurable blueprint Using newly developed algorithms, the Volkswagen experts have laid the foundation for simulating and optimizing the chemical structure of high-performance electric vehicle batteries on a quantum computer. In the long term, such a quantum algorithm could simulate the chemical composition of a battery on the basis of different criteria such as weight reduction, maximum power density or cell assembly and provide a design which could be used directly for production. This would significantly accelerate the battery development process, which has been time-consuming and resource-intensive to date.

Why the Future of Brain Enhancement and Mental Health is Digital and Pervasive

Posted by in categories: biotech/medical, health, neuroscience

It was a great pleasure to share latest data and insights with a fantastic community of researchers, engineers, innovators and investors last week, hosted by the Imperial College Centre for Neurotechnology in London. Hope you enjoy the overview slides!

Presentation by Alvaro Fernandez hosted by the Imperial College Centre for Neurotechnology in London.

Description: As seen in patent and investment trends, research findings and consumer/patient behaviors, Mental Health and Brain Enhancement are rapidly evolving in transformational ways which some call “empowering” and some “controversial.” Alvaro Fernandez, Editor-in-Chief of independent market research firm SharpBrains, will present and discuss the latest market data and forecasts on how digital platforms are poised to revolutionize brain & mental health diagnostics, monitoring, therapies and enhancement.

Can Machines Design? An Artificial General Intelligence Approach

Posted by in categories: futurism, robotics/AI

Abstract: Can machines design? Can they come up with creative solutions to problems and build tools and artifacts across a wide range of domains? Recent advances in the field of computational creativity and formal Artificial General Intelligence (AGI) provide frameworks for machines with the general ability to design. In this paper we propose to integrate a formal computational creativity framework into the G” odel machine framework. We call this machine a design G” odel machine. Such a machine could solve a variety of design problems by generating novel concepts. In addition, it could change the way these concepts are generated by modifying itself. The design G” odel machine is able to improve its initial design program, once it has proven that a modification would increase its return on the utility function. Finally, we sketch out a specific version of the design G” odel machine which specifically aims at the design of complex software and hardware systems. Future work could be the development of a more formal version of the Design G” odel machine and a potential implementation.

Here’s my speech and panel participation from yesterday at the Annual Danish Top Executive Annual Summit via VL-dognet 2018: It was covered by Danish Jyskebank TV. My panel included a minister, an ambassador, a country company head, a television host, and Sophia the Robot. I had a great time at the wonderful event (hosted at a castle), and the Danish people are very nice. The Vice President of the EU spoke a few sessions before me. My solo speech that started my afternoon session was on the future of politics and transhumanism. It’s the first 10 minutes of the video:

Edward Snowden: ‘The people are still powerless, but now they’re aware’

Posted by in categories: encryption, privacy, security

Developers at major technology companies, outraged by the Snowden disclosures, started pushing back. Some, such as those at WhatsApp, which was bought by Facebook a year after the story broke, implemented their own encryption. Others, such as Yahoo’s Alex Stamos, quit rather than support further eavesdropping. (Stamos is now the head of security at Facebook.)

Five years after historic NSA leaks, whistleblower tells the Guardian he has no regrets.

The Trump Self-Defense Doctrine for the New Space Era

Posted by in categories: security, space

A new space era is dawning and will be upon us by the early 2020s. In the face of emerging novel threats and vulnerabilities, whether the self-defense doctrine allows us to counter the threat before the attack occurs can make the difference between peace and war.

President Trump unveiled the America First National Space Strategy on March 23 covering both commercial and civil space, and national security space. This important document has drawn few comments, which are typified by the observation of founder and editor Marcia Smith that “the Trump strategy contains little that is new.”

Indeed, most of the national security provisions, which are the focus of this article, are only different in rhetoric but not in substance from those of the Obama administration and it’s predecessors. However, that they are the same is fine because they are equally essential for the new space era.
