Weird, right?

The team’s critical insight was to construct a “viral language” of sorts, based purely on its genetic sequences. This language, if given sufficient examples, can then be analyzed using NLP techniques to predict how changes to its genome alter its interaction with our immune system. That is, using artificial language techniques, it may be possible to hunt down key areas in a viral genome that, when mutated, allow it to escape roaming antibodies.

It’s a seriously kooky idea. Yet when tested on some of our greatest viral foes, like influenza (the seasonal flu), HIV, and SARS-CoV-2, the algorithm was able to discern critical mutations that “transform” each virus just enough to escape the grasp of our immune surveillance system.

Summary: Better glucose uptake compensates for age-related motor deterioration and extends lifespan in fruitflies.

Researchers from Tokyo Metropolitan University have discovered that fruit flies with genetic modifications to enhance glucose uptake have significantly longer lifespans.

No that’s not clickbait.
Being able to stop and reverse aging is probably something every single person has yearned for at some point in their life. Now researchers are finally seeing successful implementations of methods for reversing aging in Animal cells. This creates the potential for countless benefits for humans. These range from simply preventing age related illness all the way to allowing women the opportunity to have kids at any point in their life when they are ready. We are living in very exciting scientific times.

Researchers from Tokyo Metropolitan University have discovered that fruit flies with genetic modifications to enhance glucose uptake have significantly longer lifespans. Looking at the brain cells of aging flies, they found that better glucose uptake compensates for age-related deterioration in motor functions, and led to longer life. The effect was more pronounced when coupled with dietary restrictions. This suggests healthier eating plus improved glucose uptake in the brain might lead to enhanced lifespans.

The brain is a particularly power-hungry part of our bodies, consuming 20% of the oxygen we take in and 25% of the glucose. That’s why it’s so important that it can stay powered, using the glucose to produce adenosine triphosphate (ATP), the “energy courier” of the body. This chemical process, known as glycolysis, happens in both the intracellular fluid and a part of cells known as the mitochondria. But as we get older, our brain cells become less adept at making ATP, something that broadly correlates with less glucose availability. That might suggest that more food for more glucose might actually be a good thing. On the other hand, it is known that a healthier diet actually leads to longer life. Unraveling the mystery surrounding these two contradictory pieces of knowledge might lead to a better understanding of healthier, longer lifespans.

A team led by Associate Professor Kanae Ando studied this problem using Drosophila fruit flies. Firstly, they confirmed that brain cells in older flies tended to have lower levels of ATP, and lower uptake of glucose. They specifically tied this down to lower amounts of the enzymes needed for glycolysis. To counteract this effect, they genetically modified flies to produce more of a glucose-transporting protein called hGut3. Amazingly, this increase in glucose uptake was all that was required to significantly improve the amount of ATP in cells. More specifically, they found that more hGut3 led to less decrease in the production of the enzymes, counteracting the decline with age. Though this did not lead to an improvement in age-related damage to mitochondria, they also suffered less deterioration in locomotor functions.

Important here is at 38:13 where he says not only is his TAME trial paid for but an organization is going to pay a billion dollars per year on aging. He was not allowed to give details but it was going to start this month. I’ll be watching for the news.

The creatures made famous by Game of Thrones went extinct some 13000 years ago. Now geneticists know a little more about where they come from.

A team of researchers at Columbia University has developed a way to allow DNA strands to store more data. In their study, published in the journal Science, the group applied a small amount of electricity to DNA strands to allow for encoding more information than was possible with other methods.

For several years, researchers have been looking for ways to increase data storage capacity—storage requirements are expected to exceed capacity in the near future as demand skyrockets. One such approach has involved encoding data into strands of DNA—prior research has shown that it is possible. In the early stages of such research, scientists manually edited strands to add characteristics to represent zeroes or ones. More recently, researchers have used the CRISPR gene editing tool. Most such studies used DNA extracted from the tissue of deceased animals. More recently, researchers have begun efforts to move the research to living animals because it will last longer. And not just in the edited strands—the information they contain could conceivably be passed on to offspring, allowing data to be stored for very long periods of time.

Back in 2017, another team at Columbia University used CRISPR to detect a certain signal—in their case, it was the presence of sugar molecules. Adding such molecules resulted in gene expressions of plasmid DNA. Over time, the editing process was improved as genetic bits were added to represent ones and zeroes. Unfortunately, the system only allowed for storing a few bits of data.

Aging is, at least for now, inevitable, and our eyes are not immune to those changes. Vision loss is, in fact, one of the top 10 causes of disability in the US., however, shows that this might be reversible in the future.

A large team of geneticists, ophthalmologists, and other scientists used a group of molecules called Yamanaka factors to turn cells in the eyes of mature mice back to a youthful state. This reversed the damage done by aging, and the cells were then able to regenerate, connect back to the brain, and vision was restored in both models of normal aging and glaucoma.
