The evolution of AAVs in cell and gene therapy

Posted by in categories: biotech/medical, evolution

AAV development for cell and gene therapy in 2023 is being impacted by manufacturing and regulation challenges, however advancing technologies offer opportunity, according to leaders in the field.

As proven by recent regulatory approvals sweeping the cell and gene therapy industry, particularly within Europe and the US, these pioneering treatments have demonstrated great capacity in helping to resolve hard-to-treat diseases.

Supermassive black hole accretion disk seen ‘on the edge’ for 1st time

Posted by in categories: cosmology, evolution

Astronomers have observed the outer edge of a disk of matter surrounding a feeding supermassive black hole for the first time.

These observations could help scientists better measure the structures that surround these cosmic monsters, understand how black holes feed on those structures and put together how this feeding influences the evolution of galaxies that house such phenomena.

Scientists Discover ‘Pure Math’ Is Written Into Evolutionary Genetics

Posted by in categories: evolution, genetics, mathematics

Mathematicians delight in the beauty of math that so many of us don’t see. But nature is a wonderful realm in which to observe beauty born out of mathematical relationships.

The natural world provides seemingly endless patterns underpinned by numbers – if we can recognize them.

Luckily for us, a motley team of researchers has just uncovered another striking connection between math and nature; between one of the purest forms of mathematics, number theory, and the mechanisms governing the evolution of life on molecular scales, genetics.

Earth’s ancient breath: Study links atmospheric oxygen and mantle chemistry

Posted by in categories: chemistry, evolution

An international team of scientists has found a crucial link between the chemistry of Earth’s deep mantle and its early atmosphere. The study uncovers new insights into the evolution of life on our planet and the surge of atmospheric oxygen.

The scientists focused their investigation on magmas formed in ancient subduction zones, areas where portions of Earth’s crust sink back into the mantle.

The experts examined a critical juncture in Earth’s history known as the Great Oxidation Event (GOE), which occurred between 2.1 and 2.4 billion years ago.

The collective intelligence of cells during morphogenesis as a model for cognition beyond the brain

Posted by in categories: biotech/medical, chemistry, ethics, evolution, neuroscience

Michael Levin talk for the Mind, Technology, and Society (MTS) talk series at UC Merced on January 23, 2023. Abstract: Each of us makes the remarkable journey from the physics and chemistry of a quiescentunfertilized egg to that of a complex human being. How can we understand the continuousprocesses that scale up minds from the tiny physiological competencies of single cells to the large-scale metacognitive capacities of large brains? Here, I will describe a framework known as TAME-Technological Approach to Mind Everywhere — which enables identifying, understanding, andrelating to unconventional cognitive agents. I will use the example of the collective intelligence ofcells during morphogenesis to illustrate how we can begin to widen the lessons of multiscale neuroscience well beyond neurons. This will be essential as we head into a future that will bepopulated by a wide range of evolved, designed, and hybrid beings with novel bodies and novelminds. I will conclude with a case study of our new synthetic biorobot (Xenobots) and a discussionof the implications of these ideas for evolution, biomedicine, and ethics.

The potential of targeting mitochondria-associated programmed cell death for age-related disease treatment

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

Scientists have recently reviewed the available literature to examine the critical roles played by mitochondria in maintaining homeostasis. The review summarized the involvement of mitochondria in age-related disease progression and highlighted its potential as a therapeutic target of these diseases. This review has been published in Experimental & Molecular Medicine.

Mitochondria is a cytoplasmic organelle in most eukaryotic cells and is enclosed by two phospholipid membranes: the inner mitochondrial membrane (IMM) and outer mitochondrial membrane (OMM). These membranes separate functionally compartmentalized structures, i.e., matrix and intermembrane space. Mitochondria contain a unique genetic code, mitochondrial DNA (mtDNA).

During evolution, most mitochondrial genes were lost or translocated to nuclei. However, genes that remained in mtDNA encode for essential translational apparatus, i.e., ribosomal RNAs and transfer RNAs. In addition, these genes also encode proteins that are key components of oxidative phosphorylation system (OXPHOS) complexes embedded in the IMM.

What If We Became Cyborgs?

Posted by in categories: cyborgs, evolution, life extension

How would it feel to control objects with your mind? Or hear colors? Or maybe even live forever? Well, if you want to find out, all you have to do is become a cyborg. How would being part machine affect us? Would it cause a greater divide between the rich and the poor? And is this the next step in human evolution?
