Scientists find worms that recently evolved the ability to regrow a complete head

Posted by in categories: evolution, neuroscience

An international group of researchers including biologists from the University of Maryland found that at least four species of marine ribbon worms independently evolved the ability to regrow a head after amputation.

Regeneration of amputated is uncommon but does exist throughout the —from salamanders, spiders and sea stars that can regrow appendages to a of ribbon worm that can regenerate an entire individual from just a small sliver of tissue. But regenerative abilities were broadly assumed to be an ancient trait that some species managed to hold on to while most others lost through evolution.

This new study, which was published in the March 6, 2019 issue of Proceedings of the Royal Society B, turns that assumption on its head. In a survey of 35 species of marine ribbon , the researchers found that the ability to regenerate an entire head, including a brain, evolved relatively recently in four .

Fifty Billion Planets In Our Milky Way Galaxy Are Likely To Be Free Floaters, Says New Study

Posted by in categories: evolution, space

Homeless free-floating planets are likely to be rampant within the Milky Way, says new study. Young, dense loose clusters of stars are pretty raucous places early in their evolution.

Bacteria in frog skin may help fight fungal infections in humans

Posted by in categories: biotech/medical, evolution, existential risks

In the past few decades, a lethal disease has decimated populations of frogs and other amphibians worldwide, even driving some species to extinction. Yet other amphibians resisted the epidemic. Based on previous research, scientists at the INDICASAT AIP, Smithsonian and collaborating institutions knew that skin bacteria could be protecting the animals by producing fungi-fighting compounds. However, this time they decided to explore these as potential novel antifungal sources for the benefit of humans and amphibians.

“Amphibians inhabit humid places favoring the growth of , coexisting with these and other microorganisms in their environment, some of which can be pathogenic,” said Smithsonian scientist Roberto Ibáñez, one of the authors of the study published in Scientific Reports. “As a result of evolution, amphibians are expected to possess that can inhibit the growth of pathogenic and fungi.”

The team first travelled to the Chiriquí highlands in Panama, where the , responsible for the disease chytridiomycosis, has severely affected populations. They collected samples from seven to find out what kind of skin bacteria they harbored.

Neutrinos seen in the clustering of galaxies

Posted by in categories: evolution, particle physics

In early times, the universe was an energetic mix of strongly interacting particles. The first particles to break free from this dense soup were neutrinos, the lightest and most weakly interacting particles of the Standard Model of particle physics. These neutrinos are still around us today, but are very hard to detect directly because they are so weakly interacting. An international team of cosmologists, including Daniel Baumann and Benjamin Wallisch from the University of Amsterdam, have now succeeded in measuring the influence of this ‘cosmic neutrino background’ on the way galaxies have become clustered during the evolution of the universe. The research was published in Nature Physics this week.

Masterpiece: “The Syntellect Hypothesis”

Posted by in categories: alien life, evolution, life extension

Foreword to the Syntellect Hypothesis.


I had the honour of writing the foreword of Alex Vikoulov’s recently published masterpiece and bestseller “The Syntellect Hypothesis”. Hereunder you can read my foreword:

“If you picked up this book, it is not unlikely that you may have heard of the early 20th century philosophical movement of Cosmism. This movement, which originated in Russia, was striving for conquering the planets and stars, for radical life extension, immortality and resurrection of our loved ones by the means of technology. Perhaps one of its most important pioneers was Konstantin Tsiolkovsky, whose aspirations did not only venture into the realm of the Macro, but also explored the Micro. He spoke of the atomic world as being animated and can thus be considered a kind of cosmist-panpsychist.

Hachimoji DNA doubles the genetic code

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

Researchers in the US have built an “alien” DNA system from eight building block letters, so expanding the genetic code from four and doubling its information density. The new system meets all of the requirements for Darwinian evolution and can also be transcribed to RNA. It will be important for future synthetic biology applications and expands the scope of molecular structures that might be capable of supporting life, both here on Earth and more widely in the universe.

One of the main characteristics of life is that it can store and pass on genetic information. In modern-day organisms, this is done by DNA using just four building blocks: guanine, cytosine, adenine and thymine (G, A, C and T). Pairs of DNA strands form a double helix with A bonding to T and C bonding to G.

Four more building blocks .
