If the Institute for Print and Media Technology at Chemnitz University of Technology has its way, many loudspeakers of the future will not only be as thin as paper, but will also sound impressive. This is a reality in the laboratories of the Chemnitz researchers, who back in 2015 developed the multiple award-winning T-Book—a large-format illustrated book equipped with printed electronics. If you turn a page, it begins to sound through a speaker invisibly located inside the sheet of paper. “The T-Book was and is a milestone in the development of printed electronics, but development is continuing all the time,” says Prof. Dr. Arved C. Hübler, under whose leadership this technology trend, which is becoming increasingly important worldwide, has been driven forward for more than 20 years.

“Considering the whole industry is still in its preliminary stage, BSN has a long way to go,” Liu said. “It’s expensive to build a blockchain. Different platforms have different structures. Data are not interchangeable. Relevant projects are hard to promote. These problems have yet to be addressed by BSN.”


Last year was a big year for blockchain projects in China after President Xi Jinping called for further development of the technology at the end of 2019, but the country continues to shun cryptocurrencies like bitcoin.

“TECLA (an acronym which stands for “Technology and Clay”) is a habitat consisting of two interconnected housing units, each covered by a semi-spherical dome. The units have been built using multiple Crane Wasp printing units operating simultaneously. Crane WASP is defined by the manufacturer as “a collaborative 3D printing system capable of printing houses” and can print various materials — such as earth-based materials, concrete mortar, and geopolymers — with a maximum speed of 300 mm/s and a maximum printing area of 50 sqm per unit. The design of the habitat features two or more “cocoon-like” housing units, whose shape vaguely resembles that of a sea urchin, in which structure, insulation, and finishes coincide. The thick raw earth walls of the units have a hollow structure consisting of several clay “waves”, which makes them at the same time relatively lightweight, resistant, and highly insulating. About 200 printing hours are required to build each unit, which consists of 350 clay layers, each 12 mm thick.”


Designed by Mario Cucinella and build by WASP, TECLA is a prototype house near Ravenna, Italy, made by 3D-printing a material based on locally-sourced clay.

The Hallmarks of Aging are well established, but what is less discussed is the impact of microbes. Viruses, including SARS-CoV-2 and HSV-1 cause mitochondrial dysfunction-more specifically, they cause mitochondria to release some of their DNA, which triggers antiviral immunity. When considering that blood levels of mitochondrial DNA increase during aging, is aging characterized by an increased viral burden?

This is the SECOND PART of the interview with Harold Katcher in Modern Healthspan YouTube channel.


Dr. Harold Katcher is a professor of Biology at the University of Maryland. He has been a pioneer in the field of cancer research, in the development of modern aspects of gene hunting and sequencing. He carries expertise in bioinformatics, chronobiology, and biotechnology. Dr. Katcher is currently working in the capacity of Chief Technical Officer at Nugenics Research exploring rejuvenation treatments in mammals.
In May 2020 there was a paper published on biorxiv about the rejuvenation of rats by over 50%. We did a review of the paper which you can find linked to above. In this interview series we talk with Dr. Harold Katcher, one of the main authors of the paper about the experiment, the steps to get validation, commercialization and how the results fit into his theories of aging.

In this video we talk about how the results from the experiment will be validated in two third party labs. One of which will use Rhesus monkeys and the other, under Dr. Greg Fahy, will use dogs.
