Chaos synchronization between linearly coupled chaotic systems

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

Chaos, as a very interesting nonlinear phenomenon, has been intensively studied in the last three decades [10], [13]. It is found to be useful or has great potential in many disciplines such as in collapse prevention of power systems, biomedical engineering applications to the human brain and heart, thorough liquid mixing with low power consumption, secret communication technology, to name just a few [10], [13], [24].

Over the last decade, many new types of synchronization have appeared: chaotic synchronization [3], [4], lag synchronization [9], adaptive synchronization [2], phase synchronization [6], and generalized synchronization [9], to mention only a few. Since the discovery of chaos synchronization [3], there has been tremendous interest in studying the synchronization of chaotic systems [10]. Recently, synchronization of coupled chaotic systems has received considerable attention [1], [2], [5], [7]. Especially, a typical study of synchronization is the coupled identical chaotic systems [1], [6].

In 1963, Lorenz found the first classical chaotic attractor [12]. In 1999, Chen found another similar but topologically not equivalent chaotic attractor [11], [21], [22], as the dual of the Lorenz system, in a sense defined by Vanĕc̆ek and C̆elikovský [23]: The Lorenz system satisfies the condition a12 a21 0 while Chen system satisfies a12 a21 0. Very recently, Lü et al. produced a new chaotic system [14], [15], which satisfies the condition a12 a21 =0, thereby bridging the gap between the Lorenz and Chen attractors [15], [16], [17].

In a week, we can tell if something slows aging

Posted by in categories: biotech/medical, life extension, robotics/AI

The early-stage development of many age-targeting compounds often involves studies of their effects on the lifespan of the transparent nematode (worm) model Caenorhabditis elegans. A highly manual process, this exercise is time-consuming and only produces data on one endpoint – lifespan.

Durham University associate professors David Weinkove and Chris Saunter invented a technology that automates measurements of movement in many large populations of worms simultaneously. Crucially, this technology goes beyond measuring lifespan, also capturing information about how worms’ health declines as they age – their healthspan.

Longevity. Technology: Together, Weinkove and Saunter have co-founded a spinout company called Magnitude Biosciences, leveraging their innovative platform to test drugs and other interventions for their capacity to prolong healthspan. We caught up with Weinkove to learn more about the background to the company and where it goes from here.

Remedium Bio closes successful $2.3m expanded seed raise

Posted by in categories: biotech/medical, life extension

Remedium Bio has announced that it has closed more than $2.3m in its expanded seed round financing. Funding from the raise is being used to study Remedium’s lead product, a single-injection gene therapy potentially capable of reversing cartilage loss; this research is being conducted in collaboration with scientists from Tufts University School of Medicine who are engaged in researching rheumatic disorders.

The financing was led by Sherwood Ventures and included participation from, LongevityTech. Fund, Primo Medical Group, Angel Star Ventures, Apis Health Angels, MicroVentures, and Guindy Alumni Angels.

Longevity. Technology: Remedium’s pipeline includes therapeutic indications in osteoarthritis, diabetes, stroke and other large unmet clinical needs.

Biotech firm wants to grow human embryos for organ harvesting

Posted by in categories: biotech/medical, genetics, life extension

A biotech firm wants to create “synthetic” human embryos that would be used to harvest organs in order to facilitate transplants and treat conditions such as infertility, genetic disease, and aging, according to researchers.

The Israel-based company, Renewal Bio, claimed that it successfully used advanced stem cell technology and artificial wombs in order to grow mouse embryos which continued to develop for several days.

Will Artificial Intelligence Take Control? Can Computers Think?

Posted by in category: robotics/AI

Headlines such as “MACHINE COMES TO LIFE” and “GOOGLE ENGINEER URGENT WARNING” have led many to believe that science fiction has become reality, with artificial intelligence reaching the level of human consciousness. What are the religious implications? And what are the facts? What do we know about how artificial intelligence really operates?
