CORRECTIONS:
- I’m currently hiring folks to help me with editing and image overlays so there may be some errors in overlays (as in this episode) as we build up a team. I ask for your patience.
- At 1 hour 27 minute mark, we overlay an image of Brian Greene. We meant to overlay an image of Michael Green, an early pioneer of string theory: https://bit.ly/michael-green-physicist.
- The image overlay of the heliocentric model is incorrect.

New collaborative research published in the journal Nature Communications by scientists from Japan, Russia and the US contains the genetic analysis on a species of African midge, which can survive a wide array of extreme conditions including large variations in temperature, extreme drought and even airless vacuums such as space. The team successfully deciphered the genetic mechanism that makes the midge invulnerable to these harsh conditions. Prof. Noriyuki Satoh and Dr. Takeshi Kawashima of Prof. Satoh’s Marine Genomics Unit, as well as Prof. Alexander Mikeyhev of the Ecology and Evolution Unit, and Mr. Manabu Fujie and Dr. Ryo Koyanagi of the DNA Sequencing Section at the Okinawa Institute of Science and Technology Graduate University have contributed to the collaboration.

The midge, Polypedilum vanderplanki, is capable of anhydrobiosis, a unique state that allows an organism to survive even after losing 97% of its body water. Anhydrobiotic organisms are also able to survive other severe conditions such as extreme temperatures ranging from 90°C to-270°C, vacuums and high doses of radiation; all of which would be lethal to most other life forms.

The midge found in northern Nigeria lives in an environment where the dry season lasts for at least six months and droughts can last up to eight months. By the time eggs have hatched and larvae have developed, the pools of water they breed in have dried up. However these dried larvae can survive in this dehydrated state for more than 17 years. “This is a very interesting kind of phenomena,” remarks Prof. Satoh. “The first descriptions of this midge were more than 60 years ago… But serious research started only ten years ago.”

What might happen after the Cybernetic Singularity? Can we refine our theological philosophies in light of new evidence? Are we alone in the Universe? Can you achieve Cybernetic Immortality? When and how can we transcend the human condition? These are some of the questions addressed in my new book THEOGENESIS: Transdimensional Propagation & Universal Expansion. This awe-inspiring volume is to be released on October 1 2021 as part of The Cybernetic Theory of Mind series and is available now to pre-order on Amazon. #THEOGENESIS #TransdimensionalPropagation #UniversalExpansion #CyberneticTheoryofMind #cybernetics #theology #futurism #posthumanism

Ecstadelic Media Group announces the release of the next book in The Cybernetic Theory of Mind series by Alex M. Vikoulov ― THEOGENESIS: Transdimensional Propagation & Universal Expansion ― available as a Kindle eBook on Amazon.

Half-billion-year-old critter belonged to an extinct group of animals.

Palaeontologists have dug up a brand new animal species from the Cambrian era, more than 500 million years ago. Remarkably, Titanokorys gainesi was about half a metre long – which is giant compared to most of the other, pinky-finger-sized species alive at the time.

“The sheer size of this animal is absolutely mind-boggling,” says Jean-Bernard Caron, from the Royal Ontario Museum (ROM) in Canada. “This is one of the biggest animals from the Cambrian period ever found.”

The Cambrian period spanned from around 541 to 485 million years ago. It was a critical time in the evolution of life on Earth because it marked a massive explosion in diversity, with most of the major groups of animals we know today emerging, from arthropods and molluscs to echinoderms and chordates (us).

Summary: Researchers have identified 2,000 genes in humans linked to longevity. The genes are associated with biological mechanisms that drive the prolongation of life in mammals, including DNA repair, coagulation, and immune response.

What determines the life expectancy of each species? This is a fundamental and highly complex question that has intrigued the field of research throughout history. From the evolutionary point of view, the major cause of these differences between species lies in their ecological adaptations. For example, life expectancy is longer in species adapted to living in trees, underground, or with large body mass, since all these adaptations reduce mortality by predation.

A cancer vaccine could be an effective way to prevent cancer from evolving and becoming resistant to treatment, new research suggests.

Scientists were investigating the use of a cancer-killing virus in clinical trials, and observed, as they had also seen in mice, that although some patients initially responded to the treatment, their tumours soon became resistant.

The researchers showed that the specific mutations causing tumour cells to become resistant to the viral treatment, could be anticipated and exploited using a vaccine which, when tested in mice, was shown to trigger the immune system to destroy treatment resistant tumour cells.

Scientists have developed a cancer vaccine that in mice was shown to trigger the immune system to destroy treatment-resistant tumor cells.

The late 21st century belongs to Superhumans. Technological progress in the field of medicine through gene editing tools like CRISPR is going to revolutionize what it means to be human. The age of Superhumans is portrayed in many science fiction movies, but for the first time in our species history, radically altering our genome is going to be possible through the methods and tools of science.

The gene-editing tool CRISPR, short for clustered regularly interspaced short palindromic repeats, could help us to reprogram life. It gives scientists more power and precision than they have ever had to alter human DNA.

Genetic engineering holds great promise for the future of humanity. A growing number of scientists including David Sinclair believe that we will soon be able to engineer and change our genes in a way that will help us live longer and healthier lives.

But how much should we really tinker with our own nature? What is the moral responsibility of scientists and humans towards future generations?

Lasers that ‘softly’ burn paper could be the next evolution in printing. Former students of the University of Technology in Delft, Netherlands, have developed a technology that can print on any kind of paper without consumables, such as toner or ink.

This technique is not unlike burning paper using a magnifying glass and sunlight.

The same principle has been created in a laboratory using an infra-red laser ray, which passes through the set of special lenses and burns the paper, printing black carbon dots.

A plant fossil from a geological formation in Scotland sheds light on the development of the earliest known form of roots. A team led by researchers at GMI – the Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences, the University of Edinburgh, and the University of Oxford realize the first 3D reconstruction of a Devonian plant based exclusively on fossil evidence. The findings demonstrate that the appearance of different axis types at branching points resulted in the evolution complexity soon after land plants evolved sometime before 400 million years ago. The results are published in eLife.

New research demonstrates how the oldest known root axed developed more than 400 million years ago. The evolution of roots at this time was a dramatic event that impacted our planet and atmosphere and resulted in transformative ecological and climate change.
