Dystopian artificial wombs would "reinvent evolution" through genetic engineering and use artificial intelligence to monitor physical features

ectolife
Last week we published an article about a dramatic decline in sperm count globally that could threaten mankind's survival - sperm count has dropped by 62% from 1973 to 2018.

Additionally, we have published numerous articles on the negative effect Covid injections have on both male and female fertility as well as the drop in birth rates, and increase in miscarriages and stillbirths after mass vaccination campaigns began.

After creating the problem, well, voila! There's a solution looming on the horizon - artificial wombs. So many people simply do not understand how fast humanity is being transformed or what's coming.

This artist's illustration shows the location and size of a hypothetical cloud of dust surrounding our solar system.
Scientists used NASA's Hubble Space Telescope to identify the presence of an unexplained glow amid the blackness of space.

The deep darkness of space might not actually be so dark in our solar system.

Astronomers analyzed over 200,000 images from NASA's Hubble Space Telescope, making tens of thousands of measurements to try to locate a residual background glow in the night sky. The project is called Skysurf, which is based at Arizona State University and involves researchers there and around the world.

The team harvested the data from the images and then subtracted the glow from planets, stars, galaxies and even ethereal zodiacal light, which is light reflecting off dust within our solar system.

Light-based computer could outpace traditional electrical chip designs

A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space.

Computer chips are made up of millions or billions of logic gates. These tiny components carry out the most basic of operations, such as checking if one bit of data matches another. It is by combining these gates in vast numbers that tasks like downloading a file, playing a video or running a computer game are managed.

Traditional chips work by ferrying electrons, but Yi Zhang at Aalto University, Finland, and his colleagues have managed to create optical logic gates that perform the same functions with light.

Optical computers have been created before, but they involve complex hardware and are limited to certain applications. Zhang says these new gates can be built from a single layer of molybdenum disulphide crystals just 0.65 nanometres thick using existing manufacturing techniques and they could be designed to carry out universal tasks in a small package.

Body defense against viral threats also regulates intestinal function and gut health

coronavirus
Besides the skin, the digestive tract is the tissue that is most exposed to environmental influences such as bacteria and viruses. Therefore, cells that form these barriers to the interior of the body also have special defence mechanisms. A research team led by Professor Dr Thorsten Hoppe has now shown that RNA interference, or RNAi for short, which is known to be a viral defence mechanism, also prevents the overproduction of the body's own proteins in intestinal cells. The study 'ER-Associated RNA Silencing Promotes ER Quality Control' has been published in the journal Nature Cell Biology.

Comment: This study is interesting because it highlights another way that normal exposure to viruses might have beneficial effects for the body, providing further support for a symbiotic relationship between viruses and human beings. See also:

Ice ages recur more frequently than previously assumed

Ross Ice Shelf, Antarctica
A chance find of an unstudied Antarctic sediment core has led University of Otago researchers to flip our understanding of how often ice ages occurred in Antarctica.

Lead author Dr Christian Ohneiser, of the Department of Geology, says it turns out they were much more frequent than previously assumed.

"Until this research, it was common knowledge that over the last million years global ice volume, which includes Antarctica's ice sheets, expanded and retreated every 100,000 years.

"However, this research shows they actually advanced and retreated much more often - every 41,000 years - until at least 400,000 years ago," he says.

The study, published in Nature Geosciences, came about after Dr Ohneiser sampled a sediment core from the Ross Sea for a different project which was designed to reconstruct the retreat of the Ross Ice Shelf after the last ice age.

"The 6.2 metre core was recovered in 2003 and placed in an archive in the US, but was not studied further. I sampled it because I was expecting the core to have a record spanning the last 10,000 or so years.

"I conducted a paleomagnetic analysis on the core, which reconstructs changes in the earth's magnetic field, and found a magnetic reversal showing it was much older and had a record spanning more than 1 million years."

Sedimentary and magnetic mineral indicators enabled Dr Ohneiser to reconstruct how big the Ross Ice Shelf, and the West Antarctic Ice Sheet which feeds the shelf, were.

This illustration provided by researchers depicts Kap Kobenhavn, Greenland, two million years ago. Scientists have analyzed 2-million-year-old DNA extracted from dirt samples in the area, revealing an ancient ecosystem unlike anything seen on Earth today.
Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. Today, it's a barren Arctic desert, but back then it was a lush landscape of trees and vegetation with an array of animals, even the now extinct mastodon.

"The study opens the door into a past that has basically been lost," said lead author Kurt Kjær, a geologist and glacier expert at the University of Copenhagen.

With animal fossils hard to come by, the researchers extracted environmental DNA, also known as eDNA, from soil samples. This is the genetic material that organisms shed into their surroundings — for example, through hair, waste, spit or decomposing carcasses.

Studying really old DNA can be a challenge because the genetic material breaks down over time, leaving scientists with only tiny fragments.

But with the latest technology, researchers were able to get genetic information out of the small, damaged bits of DNA, explained senior author Eske Willerslev, a geneticist at the University of Cambridge. In their study, published Wednesday in the journal Nature, they compared the DNA to that of different species, looking for matches.

A dialogue with ChatGPT on Intelligent Design

Here is an interesting chat between me and OpenAI's ChatGPT on the topic of intelligent design. Interesting especially how it ended. Think of ChatGPT as a context-dependent natural language generator that tries to respond relevantly to textual prompts from human users to simulate conversation. The first of these conversation bots goes back to the 1960s with Joseph Weizenbaum's Eliza program. The current incarnation of these programs have become much more sophisticated, exploiting machine learning and big data.

Comment: LOL. Caught in an evolutionary dead end?

University of Minnesota Twin Cities researchers have discovered a new method to move objects using ultrasound waves, opening the door for using contactless manipulation in industries such as robotics and manufacturing. In the above image, University of Minnesota students Matthew Stein, Yujie Luo, and Sam Keller interact with an object that has a metamaterial surface.
The study is published in Nature Communications, a peer-reviewed, open-access scientific journal.

While it's been demonstrated before that light and sound waves can manipulate objects, the objects have always been smaller than the wavelength of sound or light, or on the order of millimeters to nanometers, respectively. The University of Minnesota team has developed a method that can move larger objects using the principles of metamaterial physics.

Metamaterials are materials that are artificially engineered to interact with waves, like light and sound. By placing a metamaterial pattern on the surface of an object, the researchers were able to use sound to steer it in a certain direction without physically touching it.

"We have known for a while that waves and light and sound can manipulate objects. What sets our research apart is that we can manipulate and trap much bigger objects if we make their surface a metamaterial surface, or a 'metasurface,'" said Ognjen Ilic, senior author of the study and the Benjamin Mayhugh Assistant Professor in the University of Minnesota Department of Mechanical Engineering.

"When we place these tiny patterns on the surface of the objects, we can basically reflect the sound in any direction we want. And in doing that, we can control the acoustic force that is exerted on an object."

Surprise kilonova upends established understanding of long gamma-ray bursts

Long gamma-ray bursts can be generated by neutron star mergers, study finds.

Artist’s impression of GRB 211211A. The kilonova and gamma-ray burst is on the right. The blue color represents material squeezed along the poles, while the red colors indicate material ejected by the two inspiralling neutron stars that is now swirling around the merged object. A disk of ejecta emitted after the merger, hidden behind the red and blue ejecta, is shown in purple. A fast jet (shown in yellow) of material punches through the kilonova cloud. The event occurred about 8 kiloparsecs from its host galaxy (left). 
For nearly two decades, astrophysicists have believed that long gamma-ray bursts (GRBs) resulted solely from the collapse of massive stars. Now, a new study upends that long-established and long-accepted belief.

Led by Northwestern University, a team of astrophysicists has uncovered new evidence that at least some long GRBs can result from neutron star mergers, which were previously believed to produce only short GRBs.

After detecting a 50-second-long GRB in December 2021, the team began searching for the long GRB's afterglow, an incredibly luminous and fast-fading burst of light that often precedes a supernova. But, instead, they uncovered evidence of a kilonova, a rare event that only occurs after the merger of a neutron star with another compact object (either another neutron star or a black hole).

In addition to challenging long-established beliefs about how long GRBs are formed, the new discovery also leads to new insights into the mysterious formation of the heaviest elements in the universe.

The research was published today (Dec. 7) in the journal Nature.

Irreparable vaccine-induced harm: Open Letter to the New Zealand government

COVID-19 vaccine surveillance and pharmacovigilance data

In my past professional life - probably a decade ago, I had a client named Dr. Charlton Brown. Dr. Brown, at the time, was CEO and co-innovator at Immune Targeting Systems Ltd (UK). I always enjoyed working with Charlton, as we share a certain curiosity for science/knowledge and a dry wit. It turns out that Charlton has been part of the medical freedom resistance and has been working to get the word out about the risks of mRNA vaccines. Up until his email to me earlier this week, I had no idea.

This isn't the first time that people from my "former" professional life have emailed me to let me know that they are supportive of what I have been doing. In fact, I had a former colleague from my time at the Salk Institute in the 1980s write to me to express their support for me this week. These emails always lift my spirits as sometimes this seems like a very lonely fight, although the people writing in the comments section of this Substack also let me know that Jill and I are not alone - and this community often saves me from my own dark musings about the state of the world.

I have no idea how many scientists and physicians are quietly, sometimes secretly, questioning the public health policies in this country and globally. But I do know that dissidents of the new normal are slowly finding their voice and are speaking out.
