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.”

Perfect cervical cancer screening results hint at the shadowy role of epigenetics

Posted by in categories: biotech/medical, genetics

Cervical cancer is the fourth most common cancer for women yet the leading cause of cancer-related death in developing countries, an unfortunate statistic that highlights the importance of access to screening. Through a comprehensive trial involving thousands of subjects, a newly designed test has been found to greatly outperform current screening methods in terms of both cost and accuracy, while also shedding new light on the mechanics at play.

World Population Might Go to 40 Billion by 2150 But We Can Already Feed All Those People

Posted by in category: futurism

Well that’s good news.


I see several parts to the problem where many people believe the doomer overpopulation myths.

The fear story resonates with deep caveman fears of starvation. Any individual person can experience hunger. This reinforces and validates the fear of potential starvation.

Understanding 3D Printing Tolerances for Engineering Fits

Posted by in categories: 3D printing, engineering

In Tutorials

Tolerance and fit are essential concepts for any engineer designing mechanical assemblies.

Accounting for tolerances ultimately optimizes both the prototyping and production processes, reducing the material cost of iteration, lowering post-processing time, and mitigating the risk of accidentally broken parts.

Journal Club December 2018 — Fisetin is a senotherapeutic that extends health and lifespan

Posted by in categories: futurism, life extension

The topic for the December Journal Club will be the recently published paper – Fisetin is a senotherapeutic that extends health and lifespan. This commonly available supplement and a plant-based polyphenol appears to influence the aging process in mice by clearing senescent cells, one of the suggested reasons we age.

One-carbon Metabolic Pathway Implicated In Age-Related Immunosenescence

Posted by in category: life extension

A recent study by Harvard Medical School scientists suggests that defective one-carbon metabolism and cellular respiration might contribute to age-related immunosenescence, the decline of immune function typically observed during aging [1].
