The biological basis of mental illness

Posted by in categories: biological, evolution, genetics, neuroscience

Psychiatry as a field, meanwhile, quivers with theoretical uncertainty. It has not become a sub-speciality of neurology, as one might have expected if mental illness mapped directly to neural behaviour. And common genetic variations with large effects on mental disorders are elusive. The various incarnations of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) have enabled diagnostic consistency and the objectification of mental illnesses. But the DSM has resulted in overlapping diagnoses, and contrived symptom-cluster checklists. At times, it impinges on the territory of healthy mental function. Allen Frances, chair of the task force that wrote the manual’s fourth edition in 1994, revolted against out-of-control mental diagnosis in his 2013 book DSM: Saving Normal.


Adrian Woolfson weighs up a study on the role of evolution in conditions such as depression and anxiety.

Research suggests life thrived on Earth 3.5 billion years ago

Posted by in category: evolution

This study provides some of the first information regarding how robustly ancient life was metabolizing. Microbial sulfate metabolism is recorded in over 3 billion years of sulfur isotope ratios that are in line with this study’s predictions, which suggest was in fact thriving in the ancient oceans. This work opens up a new field of research, which ELSI Associate Professor Shawn McGlynn calls “evolutionary and isotopic enzymology.” Using this type of data, scientists can now proceed to other elements, such as carbon and nitrogen, and more completely link the geochemical record with cellular states and ecology via an understanding of enzyme evolution and Earth history.

Who’s afraid of transhumanism? (We all should be)

Posted by in categories: biological, evolution, life extension, transhumanism

Project fear? Should we pay attention to American Jesuits?


But the fundamental ambition of transhumanism is more problematic. Its architects champion a use of technology to accelerate the evolution of humanity so radically that at the end of the process humanity as such would disappear. A superior posthuman being would emerge. According to Wikipedia, “Transhumanism is the intellectual and cultural movement that affirms the possibility and desirability of fundamentally improving the human condition through applied reason, especially by developing and making widely available knowledge to eliminate aging and to greatly enhance human intellectual, physical, and psychological capacities.” From its inception, the abolition of human death and aging has been one of the goals of transhumanism as it engineers a new being freed from the biological constraints of the current human condition.

From its inception, the abolition of human death and aging has been one of the goals of transhumanism.

AHS18 Michael Rose — Evolutionary Biology of Diet, Aging, and Mismatch

Posted by in categories: biological, evolution, life extension, mathematics

Human health depends on age and evolutionary history. Firstly, adaptation is age-specific, with Hamilton’s forces of natural selection leading to much greater adaptation at earlier ages than later ages. This of course is how evolutionary biologists explain the existence of aging in the first place. Secondly, when environmental conditions change, it takes surprisingly few generations for populations to adapt to such new conditions, at least at early ages when natural selection is intense. Thirdly, at later ages, when the forces of natural selection are weak, natural selection will often fail to produce adaptation to a selective environment that is not evolutionarily ancient. All three of these themes will be illustrated using both explicit mathematical theory and findings from experimental evolution. At the end of the presentation, we will apply these general scientific insights to the case of human evolutionary history, human aging, and optimal human diets.

A cure for cancer? Israeli scientists say they think they found one

Posted by in categories: biotech/medical, evolution

A small team of Israeli scientists think they might have found the first complete cure for cancer.

“We believe we will offer in a year’s time a complete cure for cancer,” said Dan Aridor, of a new treatment being developed by his company, Accelerated Evolution Biotechnologies Ltd. (AEBi), which was founded in 2000 in the ITEK incubator in the Weizmann Science Park. AEBi developed the SoAP platform, which provides functional leads to very difficult targets. “Our cancer cure will be effective from day one, will last a duration of a few weeks and will have no or minimal side-effects at a much lower cost than most other treatments on the market,” Aridor said. “Our solution will be both generic and personal.”

It sounds fantastical, especially considering that an estimated 18.1 million new cancer cases are diagnosed worldwide each year, according to reports by the International Agency for Research on Cancer. Further, every sixth death in the world is due to cancer, making it the second leading cause of death (second only to cardiovascular disease).

Evolution calls on us to lose weight slowly over time

| Local | http://idahostatejournal.com/ Cutting calories (dieting) and increasing caloric expenditure (exercise) cause your brain to activate neurons that will not allow you to utilize fat or lose weight.


Recently, and at a most appropriate time, another study published in the journal eLife has given explanation as to why your current New Year’s Resolution diet will not work.

About 10,000 light years away from Earth, a black hole is engaged in a stellar feast, devouring the gases of a nearby star.


A stellar meal provides tantalizing new evidence about black hole evolution.

Synthetic organisms are about to challenge what ‘alive’ really means

Posted by in categories: evolution, space

And there will be increasing pressures to continue this research. We may need to accelerate the evolution of terrestrial life forms, for example, including homo sapiens, so that they carry traits and capabilities needed for life in space or even on our own changing planet.

All of this will bring up serious issues as to how we see ourselves – and behave – as a species. While the creation of multicellular organisms that are capable of sexual reproduction is still a long way off, in 2019 we will need to begin a serious debate about whether artificially evolved humans are our future, and if we should put an end to these experiments before it is too late.

Scientists develop method to visualize a genetic mutation

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

A team of scientists has developed a method that yields, for the first time, visualization of a gene amplifications and deletions known as copy number variants in single cells.

Significantly, the breakthrough, reported in the journal PLoS Biology, allows early detection of rare genetic events providing high resolution analysis of the tempo of evolution. The method may provide a new way of studying mutations in pathogens and .

“Evolution and disease are driven by mutational events in DNA,” explains David Gresham, an associate professor in New York University’s Department of Biology and the study’s senior author. “However, in populations of these events currently cannot be identified until many cells contain the same mutation. Our method detects these rare events right after they have happened, allowing us to follow their trajectory as the population evolves.”
