Model suggests how ancient RNA may have gained self-cutting ability essential for life

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

Scientists have long pondered the beginnings of life on Earth. One theory is that RNA, which is ubiquitous across all domains of life, played a central role in early life. Similar to DNA, RNA possesses the ability to store genetic information. However, to initiate life’s processes, early RNA must have also possessed the capability to self-replicate and catalyze biochemical reactions independently, without the assistance of specialized enzymes.

Can Transhumanism Rescue The West From The Threat Of AI?

Posted by in categories: biotech/medical, genetics, geopolitics, robotics/AI, transhumanism

Here’s a new Forbes review by world leading futurist Tracey Follows on the book: Transhuman Citizen:


What does Transhumanism, Ayn Rand and the U.S. Presidential election have in common? They are the connecting themes in a new book by Ben Murnane entitled, “Transhuman Citizen”

The book tells the story of Zoltan Istvan, a one-time U.S. Presidential candidate, who drove a coffin-shaped bus around the U.S. attempting to persuade the public that death is not inevitable and that transhumanism is a political as much as a scientific solution to the troubles of the 21st Century.

Clinical trial: Some sarcoma patients improve with T cell immunotherapy

Posted by in categories: biotech/medical, genetics

A clinical trial led by researchers at Washington University School of Medicine in St. Louis has shown that a T cell immunotherapy—in which the patients’ own T cells are genetically modified to attack and kill cancer cells—is effective in treating some patients with rare cancers of the body’s soft tissues.

Genetic Variants and Cannabis: Unraveling Risk Factors for CUD

Posted by in categories: biotech/medical, genetics

“The increases in THC levels found in cannabis could mimic some of the more pronounced effects that we see for people who are slower metabolizers,” said Dr. Christal Davis.


How can genetics influence cannabis consumption? This is what a recent study published in Addictive Behaviors hopes to address as a team of researchers investigated a link between how genetic variances influence how a person metabolizes THC, which could not only determine future use but also the chances of succumbing to cannabis use disorder, or CUD. This study holds the potential to help cannabis users, medical professionals, legislators, and the public better understand the physiological influences of cannabis use, even at the molecular level.

For the study, the researchers enlisted 54 participants between 18–25 years of age, 38 of whom suffered from CUD while the remaining 16 suffered from non-CUD substance abuse. It has been determined that individuals aged 18–25 have a three times greater likelihood of having CUD compared to individuals over the age of 26. After obtaining blood samples from each participant, the researchers tested them for differences in gene markers, specifically pertaining to THC-metabolizing enzymes. Additionally, each participant was instructed to fill out a questionnaire regarding their experiences with cannabis use and how it makes them feel when they use it.

Groundbreaking study shows how lifestyle changes can reverse biological aging

Posted by in categories: biological, genetics, life extension

In a groundbreaking study led by Dr. Karen Fitzgerald, six women between the ages of 45 and 65 experienced a remarkable reduction in their biological age by an average of five years in just eight weeks. The findings offer promising insights into the potential of lifestyle changes to combat aging.

The study, which focused on the distinction between chronological age and biological age, revealed that while chronological age remains fixed, biological age — the age of one’s cells — can be influenced and even reversed through targeted interventions.

Using Dr. Steven Horvath’s epigenetic clock, which measures 353 markers associated with methylation changes linked to aging, the researchers assessed the participants’ biological age before and after the intervention.

‘Exhausted’ immune cells in healthy women could be target for breast cancer prevention

Posted by in categories: biotech/medical, genetics

Everyone has BRCA1 and BRCA2 genes, but mutations in these genes—which can be inherited—increase the risk of breast and .

The study found that the in breast tissue of healthy women carrying BRCA1 or BRCA2 gene mutations show signs of malfunction known as exhaustion. This suggests that the immune cells can’t clear out damaged breast cells, which can eventually develop into breast cancer.

This is the first time that exhausted immune cells have been reported in non-cancerous breast tissues at such scale—normally these cells are only found in late-stage tumors. The results raise the possibility of using existing immunotherapy drugs as early intervention to prevent breast cancer developing, in carriers of BRCA1 and BRCA2 gene mutations.

Unlocking TNA: Researchers Develop Artificial Building Blocks of Life

Posted by in categories: biotech/medical, genetics

Groundbreaking research has led to the creation of threofuranosyl nucleic acid (TNA), offering enhanced stability and therapeutic potential, with applications in drug delivery and diagnostics.

The DNA carries the genetic information of all living organisms and consists of only four different building blocks, the nucleotides. Nucleotides are composed of three distinctive parts: a sugar molecule, a phosphate group, and one of the four nucleobases adenine, thymine, guanine, and cytosine. The nucleotides are lined up millions of times and form the DNA double helix, similar to a spiral staircase.
