Investigators discover new mechanism to boost RNA therapies

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

Investigators from the Smidt Heart Institute at Cedars-Sinai have identified how biological pacemaker cells—cells that control your heartbeat—can “fight back” against therapies to biologically correct abnormal heartbeat rates. The research also uncovered a new way to boost the effectiveness of RNA therapies by controlling this “fighting back” activity.

This novel concept, published today in the peer-reviewed journal Cell Reports Medicine, is an important step in the evolution and creation of biological pacemakers—which aim to one day replace traditional, electronic pacemakers.

“We are all born with a specialized group of heart that set the pace for our heartbeats,” said Eugenio Cingolani, MD, senior author of the study and director of the Cardiogenetics Program in the Smidt Heart Institute at Cedars-Sinai. “But in some people, this natural is too slow, leading to the need for an electronic pacemaker.”

Transhumanism and Human Genetic Engineering — ROBERT SEPEHR

Posted by in categories: bioengineering, genetics, life extension, nanotechnology, robotics/AI, transhumanism

Transhumanism advocates the use of current and emerging technologies such as genetic engineering, artificial intelligence, and nanotechnology, to augment human capabilities, enhance longevity, and improve cognition. The term “designer baby” refers to a child who would develop from an embryo or sperm or egg that had been genetically altered. Is there a covert political agenda behind this allegedly altruistic scientific movement?

Robert Sepehr is an anthropologist and author.

How CRISPR lets us take the next step in evolution | Max Plach | TEDxOTHRegensburg

Posted by in categories: biotech/medical, computing, ethics, genetics

Biophysist and Biochemist Dr. Maximilian Plach talks about a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called “designer babies.” Max reviews how CRISPR-Cas9 works — and asks the scientific community to pause and discuss the ethics of this new tool. Max has earned his PhD in biophysics and computational biology at the University of Regensburg, Germany. He is now Chief Scientific Officer of 2bind, a dynamic and growing company focused on providing biophysical research services for biotech and pharma industries. It is therefore no wonder that Max closely follows the latest breakthroughs and developments in biotech and biomedical technology. He is a long viewer and listener of TED talks; the more exotic, the better. Or who doesn’t remember the talk about the world’s worst city flags? This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Organotypic cultures as aging associated disease models

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

Aging remains a primary risk factor for a host of diseases, including leading causes of death. Aging and associated diseases are inherently multifactorial, with numerous contributing factors and phenotypes at the molecular, cellular, tissue, and organismal scales. Despite the complexity of aging phenomena, models currently used in aging research possess limitations. Frequently used in vivo models often have important physiological differences, age at different rates, or are genetically engineered to match late disease phenotypes rather than early causes. Conversely, routinely used in vitro models lack the complex tissue-scale and systemic cues that are disrupted in aging.

Scientists Discover Four Critical Genes Tied to Suicide

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

A study published Wednesday in the JAMA Psychiatry journal shows that four key genetic variations are more common in military veterans who have taken their own life or considered it.

Scientists from Duke University in Durham, North Carolina, found the pattern while analyzing blood samples from a database that included 633,778 U.S. veterans, cross-referenced with the International Suicide Genetics Consortium of more than 549,000 individuals.

The obtained samples were sequenced to create genetic profiles compared to participants’ medical records, showing that 121,211 recorded cases of attempted suicide or thoughts about killing themselves.
