On December 2nd, we brought you the news that Microsoft Research developed a new method that allows it to read and write much faster in DNA format. In the last month or so, three other new developments have popped up in DNA storage.
Scientists at the Center for Synthetic Biology from the Northwestern University, Illinois, have revealed a demonstration on DNA storage encoding that manages to fulfill three bits of information in an hour, according to Technology Networks. This new method “relies on an enzymatic system.”
Then, a team from the Georgia Tech Research Institute (GTRI) has devised a microchip that can significantly improve the speed at which data can be written in DNA form, according to the BBC. The team expects a 100x improvement over current technologies for DNA storage.
Finally, a team in China at Southeast University in the country’s Jiangsu Provincemade has been reported to be engineering a new process that could produce the first mass-market DNA storage device, according to TechRadar.
Combining knowledge of chemistry, physics, biology, and engineering, scientists from McGill University develop a biomaterial tough enough to repair the heart, muscles, and vocal cords, representing a major advance in regenerative medicine.
“People recovering from heart damage often face a long and tricky journey. Healing is challenging because of the constant movement tissues must withstand as the heart beats. The same is true for vocal cords. Until now there was no injectable material strong enough for the job,” says Guangyu Bao, a PhD candidate in the Department of Mechanical Engineering at McGill University.
The team, led by Professor Luc Mongeau and Assistant Professor Jianyu Li, developed a new injectable hydrogel for wound repair. The hydrogel is a type of biomaterial that provides room for cells to live and grow. Once injected into the body, the biomaterial forms a stable, porous structure allowing live cells to grow or pass through to repair the injured organs.
This is the same type of double double DOUBLE down on hyperbolic and aggressive anti expert BS that has pushed a not insignificant portion of the population of the US to throw a violent tantrum against covid19 vaccines and wearing a piece of cloth on their face to keep from DYING. Similarly, ultra environmentalists on the far left have ceased to try to protect the environment FOR future generations. Now they want to protect the environment FROM future generations. They’ve become ANTIHUMAN, often to a disturbingly horrific — if hilariously stupid — extent. LITERALLY. Unless you think we shouldn’t build anything on the sterile, irradiated and dead surface of the moon by polluting it — or any other moon, asteroid, or planet by stepping on it’s surface with our filthy monkey feet. Or throwing trash into the SUN because we’d be…
👉😏🙄POLLUTING IT!🙄🤪👈
There is a reason why experts are experts. It isn’t because they want to eat children on pizza with Hillary Clinton with space lizards, nor because they want an irradiated earth beneath their feet. Nuclear power is clean, cheap, and safe. Until fusion gets here, and with electric vehicles quickly becoming the dominant mode of transportation every minute that ticks by, nuclear power isn’t just preferential, its absolutely REQUIRED if we want to get a handle on global warming while simultaneously maintain or improve the standard and quality of life we are accustomed to, and that developing nations will, already are, and SHOULD be seeking for themselves too. Building nuclear power into the foundation of a developing nations energy generation and distribution infrastructure from day one will PREVENT all the massive amount of damage that will inevitably exponentially accelerate global warming and pollution, lowering the quality of life in that nation which will in turn prompt even GREATER use of fossil fuels to mitigate temporarily. Heat caused by fossil fuel powered global warming is dealt with symptomatically by turning up the air-conditioning. Dangerous spikes in particulates and pollution in the air is symptomatically dealt with by using high energy consuming industrial or home air filtration systems, etc. If all that energy comes from coal or other fossil fuels, that lovely tesla you’ve got plugged in to charge in your garage overnight is doing just as much damage to the environment as that douchebag down the street with his fire eagle painted hummer filling up on gasoline before he goes to a kid Rock show that he’s actually LOOKING FORWARD TO!

Due to last years success, I am back with an updated list of my 5 most promising anti-aging compounds.
There are more than 200 different geroprotective compounds. Some of these are already available as supplements, some are in clinical trials and some have FDA approval. Which are my top 5 that I think i most promising in terms of their anti-aging effects (so focusing more on healthspan than lifespan). And note the use of “promising” — there is still much work to be done to better investigate the long-term safety, dose and timings of different supplements which you should always bear in mind.
Anyway, I made this video more for a bit of fun and to make a longer summary video to pull ideas together from multiple previous videos with some new info too! So hope you like it! And disclaimer — this is not recommendation or health advise — i am not a medical doctor!!
Few developments have rocked the biotechnology world or generated as much buzz as the discovery of CRISPR-Cas systems, a breakthrough in gene editing recognized in 2020 with a Nobel Prize. But these systems that naturally occur in bacteria are limited because they can make only small tweaks to genes. In recent years, scientists discovered a different system in bacteria that might lead to even more powerful methods for gene editing, given its unique ability to insert genes or whole sections of DNA in a genome.
New research from The University of Texas at Austin dramatically expands the number of naturally occurring versions of this system, giving researchers a wealth of potential new tools for large-scale gene editing.
Other scientists had identified clusters of genes that use CRISPR to insert themselves into different places in an organism’s genome, dubbed CRISPR-associated transposons (CASTs). Earlier work has shown they can be used to add an entire gene or large DNA sequence to the genome, at least for bacteria.
Roddenberry Entertainment has created a non-fungible token (NFT) of sci-fi legend Gene Roddenberry’s signature on the first-ever Star Trek contract. It will be stored on the DNA code of bacteria.
Scientific ingenuity means cameras keep on getting smaller and smaller, and the latest to appear is not only incredibly tiny – the same size as a grain of salt – it’s also able to produce images of much better quality than a lot of other ultra-compact cameras.
Using a technology known as a metasurface, which is covered with 1.6 million cylindrical posts, the camera is able to capture full-color photos that are as good as images snapped by conventional lenses some half a million times bigger than this particular camera.
And the super-small contraption has the potential to be helpful in a whole range of scenarios, from helping miniature soft robots explore the world, to giving experts a better idea of what’s going on deep inside the human body.

Science isn’t all lab coats and test tubes. Beautiful visuals can engage people—especially students—and inspire them to learn about science more broadly.
Scientists have often invited the public to see what they see, using everything from engraved woodblocks to electron microscopes to explore the complexity of the scientific enterprise and the beauty of life. Sharing these visions through illustrations, photography, and videos has allowed laypeople to explore a range of discoveries, from new bird species to the inner workings of the human cell.
As a neuroscience and bioscience researcher, I know that scientists are sometimes pigeonholed as white lab coats obsessed with charts and graphs. What that stereotype misses is their passion for science as a mode of discovery. That’s why scientists frequently turn to awe-inducing visualizations as a way to explain the unexplainable.
