Mushrooms Are A Highly Evolved Extraterrestrial Species — Organic Internet [VIDEO]

Posted by in categories: alien life, genetics, internet, life extension, robotics/AI

It is a crazy thought, right?! To think that mushrooms could be alien life. But before you dismiss the idea, take a look at some of principles of the theory. The main concept was formulated by the ingenious psychonaut philosopher Terrence McKenna, and goes along following lines.

Like no other form of life on our planet, the spores of mushrooms are almost perfectly suited to space travel. They can survive high vacuum and insanely low temperatures; the casing of a spore is one of the most electron dense materials in nature, to the point where McKenna says it is almost akin to a metal; global currents are even able to form on the quasi-metallic surface of an airborne spore, which then acts as a repellent to the extreme radiation of space. It is a mind boggling thought that something could evolve to be so perfectly suited to explore the universe.

An Interview with Prof. Vittorio Sebastiano of Turn.Bio

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

We recently attended the Undoing Aging Conference in Berlin and had the opportunity to interview Professor Vittorio Sebastiano of Turn. Bio, a company developing partial cellular reprogramming techniques to reverse cellular aging.

As we age, our cells experience changes to their epigenetic markers, and this, in turn, changes gene expression, which is proposed to be a primary reason we age. Recently, there has been considerable interest in resetting these epigenetic markers to reverse cellular aging; induced pluripotent stem cell (iPSC) creation uses similar techniques.

Could deafness be reversed? Scientists re-grow damaged hair cells that have been killed off by age or noise inside the ear…


Researchers from the University of Rochester found that viruses, genetics and even existing drugs could cause little hairs to regrow in the inner ear. These hairs pick up on noises entering the ear.

Chinese, US researchers create monkeys with human-like brain development

Posted by in categories: genetics, neuroscience

A group of monkeys were found to have “human-like” brain development, including faster reactions and better memories, after a joint Sino-American team of researchers spliced a human gene into their genetic makeup.

Researchers from the Kunming Institute of Zoology at the Chinese Academy of Sciences (CAS), and the University of North Carolina in the United States modified the genes of 11 monkeys (eight first-generation and three second-generation) with the addition of copies of the human gene MCPH1.

Microcephalin (MCPH1) is a key factor in our brain development and, in particular, eventual brain size. Mutations in the gene can lead to the developmental disorder microcephaly, which is characterized by a tiny brain.

By Far the Strangest Scientific Discovery of 2018: Your Memories Are a Viral Infection

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

Agree or Disagree?


According to two papers published in Cell on January 11, 2018, the making of memories and the processes of learning resemble, of all things, a viral infection. It works like this: The shells that transport information between neurons are assembled by a gene called Arc. Experiments conducted by two research teams revealed that the Arc protein that forms a shell, functions much like a Gag, a gene that transports a virus’s genetic material between cells during an infection. For example, the retrovirus HIV uses a Gag in exactly this manner.

Nature versus nurture: Environment exerts greater influence on corn health than genetics

Posted by in categories: biological, food, genetics, health, sustainability

Oops, duh, Eureka… shouted Archimedes… Or something.


Corn leaves are teaming with bacteria communities (the leaf “microbiome”) that influence plant health and performance, and scientists are still figuring out how. A team of scientists led by Dr. Jason Wallace recently published a study in the open access Phytobiomes Journal that advances what we know about these bacterial communities by investigating their relationships with corn genetics. According to Dr. Wallace, “the end-goal of all this research is to understand how crops interact with their microbial communities so we can harness them to make agriculture more productive and sustainable.”

In one of the largest and most diverse leaf microbe studies to date, the team monitored the active bacteria on the leaves of 300 diverse lines of corn growing in a common environment. They were especially interested to see how corn genes affected bacteria and found there was little relationship between the two — in fact, the bacteria were much more affected by the environment, although genetics still had a small role.

This is an interesting discovery that “breeding probably isn’t the best way to address this,” Dr. Wallace says. Instead, “the leaf community is probably better changed through farmer management.” That is, farmers should be able to change growing practices to enhance their current crops rather than seek out new plant varieties.

Study debunks ‘depression genes’ hypotheses

Posted by in categories: genetics, neuroscience

Using genetic and survey data gathered from individuals via the UK Biobank, 23andMe, and the Psychiatric Genomics Consortium, they set out to see if any of the genes, or gene variants, were associated with depression either alone or when combined with an environmental factor like childhood trauma or socioeconomic diversity.


A new study assessing data from 620,000 individuals found that the 18 most highly-studied candidate genes for depression are no more associated with depression than randomly chosen genes.

Depression genes debunked: analysis dashes highly studied link

Posted by in categories: genetics, neuroscience

Research out of the University of Colorado Boulder has dashed research into a potential link between certain genes and depression. The conclusion follows an analysis of both survey and genetic data from more than half a million people, which found that 18 candidate genes and random genes were equally associated with cases of depression.

The new study, which was recently published in the American Journal of Psychiatry, looked at 18 highly-studied ‘candidate genes,’ each of which had previously been studied in association with depression a minimum of 10 times. The results were called “a little bit stunning” by study senior author Matthew Keller.

According to the study, these 18 candidate genes weren’t associated with depression more than other randomly chosen genes. Past research into the genes that had indicated a link between the two were called false positives, though the researchers caution that this doesn’t mean depression isn’t heritable.

‘Jumping genes’ drive many cancers

Posted by in categories: biotech/medical, genetics

Wang and his colleagues found that many cancers that get switched into overdrive and boost tumor growth have jumping genes that function as a kind of stealthy “on switch.” These cryptic switches can force a gene to be turned on all the time, even though it should be off.


Mistakes in DNA are known to drive cancer growth. But a new study, from Washington University School of Medicine in St. Louis, heavily implicates a genetic phenomenon commonly known as “jumping genes” in the growth of tumors.

The study is published March 29 in the journal Nature Genetics.
