Great new episode with renowned geneticist Christopher Mason who talks about his book on how we will need to bioengineer our own species in order to expand beyond our solar system.

Geneticist Christopher Mason chats about his new book, “The Next 500 Years: Engineering Life to Reach New Worlds” from MIT Press. We discuss both the nuts and bolts and the philosophy driving our expansion offworld. Mason’s goal is to preserve our species by expanding to an Earth 2.0 in order to avoid our star’s own Red Giant endgame.

First discovered in 1984, retrons are floating ribbons of DNA in some bacteria cells that can be converted into a specific type of DNA—a single chain of DNA bases dubbed ssDNAs (yup, it’s weird). But that’s fantastic news for gene editing, because our cells’ double-stranded DNA sequences become impressionable single chains when they divide. Perfect timing for a retron bait-and-switch.

Normally, our DNA exists in double helices that are tightly wrapped into 23 bundles, called chromosomes. Each chromosome bundle comes in two copies, and when a cell divides, the copies separate to duplicate themselves. During this time, the two copies sometimes swap genes in a process called recombination. This is when retrons can sneak in, inserting their ssDNA progeny into the dividing cell instead. If they carry new tricks—say, allowing a bacteria cell to become resistant against drugs—and successfully insert themselves, then the cell’s progeny will inherit that trait.

Because of the cell’s natural machinery, retrons can infiltrate a genome without cutting it. And they can do it in millions of dividing cells at the same time.

Widely used to monitor and map biological signals, to support and enhance physiological functions, and to treat diseases, implantable medical devices are transforming healthcare and improving the quality of life for millions of people. Researchers are increasingly interested in designing wireless, miniaturized implantable medical devices for in vivo and in situ physiological monitoring. These devices could be used to monitor physiological conditions, such as temperature, blood pressure, glucose, and respiration for both diagnostic and therapeutic procedures.

To date, conventional implanted electronics have been highly volume-inefficient—they generally require multiple chips, packaging, wires, and external transducers, and batteries are often needed for energy storage. A constant trend in electronics has been tighter integration of electronic components, often moving more and more functions onto the integrated circuit itself.

Researchers at Columbia Engineering report that they have built what they say is the world’s smallest single–chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly. The study was published online May 7 in Science Advances.

7:01 they talk about Church’s comments of ending aging by 2030. Also this appears to be a part one.

In this video Professor Church talks about his theory of aging and touches on his ideas on the future of aging.

I still don’t get how there seems to be No organized effort anywhere to achieve the ability to 3D print a perfect genetic match of all organs by 2025 — 2030. You would think some government somewhere would want to work round the clock on this.

NIBIB-funded engineers at the University of Buffalo have fine-tuned the use of stereolithography for 3D printing of organ models that contain live cells. The new technique is capable of printing the models 10–50 times faster than the industry standard-;in minutes instead of hours-; a major step in the quest to create 3D-printed replacement organs.

Conventional 3D printing involves the meticulous addition of material to the 3D model with a small needle that produces fine detail but is extremely slow —taking six or seven hours to print a model of a human part, such as a hand, for instance. The lengthy process causes cellular stress and injury inhibiting the ability to seed the tissues with live, functioning cells.

Getting closer.

Drugs and vaccines circulate through the vascular system reacting according to their chemical and structural nature. In some cases, they are intended to diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the side effects it causes —are a function of how well it can reach its target.

“A lot of medicines involve intravenous injections of drug carriers,” said Ying Li, an assistant professor of mechanical engineering at the University of Connecticut. “We want them to be able to circulate and find the right place at the right time and to release the right amount of drugs to safely protect us. If you make mistakes, there can be terrible side effects.”

Harvard’s Wyss Institute has created a new gene-editing tool that enable scientist to perform millions of genetic experiments simultaneously.

Researchers from the Harvard’s Wyss Institute for Biologically Inspired Engineering have created a new gene-editing tool that can enable scientists to perform millions of genetic experiments simultaneously. They’re calling it the Retron Library Recombineering (RLR) technique, and it uses segments of bacterial DNA called retrons that can produce fragments of single-stranded DNA.

When it comes to gene editing, CRISPR-Cas9 is probably the most well-known technique these days. It’s been making waves in the science world in the past few years, giving researchers the tool they need to be able to easily alter DNA sequences. It’s more accurate than previously used techniques, and it has a wide variety of potential applications, including life-saving treatments for various illnesses.
