A New Technology Could Help Solve a DNA Mystery
The human genome’s inner workings could be revealed through new Cornell-developed technology.
Researchers from Oxford Nanopore Technologies, Weill Cornell Medicine, and the New York Genome Center have created a new technique to evaluate the three-dimensional structure of the human DNA, or how the genome folds, on a massive scale. The genome is the entire set of genetic instructions, either DNA or RNA, that allow an organism to function.
Using this technique, the researchers showed that groups of simultaneously interacting regulatory elements in the genome, as opposed to pairs of these elements, may influence cell activity, including gene expression. Their research, which was recently published in the journal Nature Biotechnology, may help clarify the connection between cellular identity and genome structure.
“Knowing the three-dimensional genome structure will help researchers better understand how the genome functions, and particularly how it encodes different cell identities,” said senior author Dr. Marcin Imieliński, associate professor of pathology and laboratory medicine and computational genomics in computational biomedicine at Weill Cornell Medicine and a core member of the New York Genome Center. “The ways that we’ve had to study genome structure have given us amazing insights, but there have also been key limitations,” he said.
For example, previous technology to examine the genome’s three-dimensional structure enabled researchers to investigate how often two loci, or physical sites on the genome, interact with one another. Traditionally, pairs of loci known as enhancers and promoters—components in the genome that interact with one another to control gene expression—have been discovered.
Information about these pairings offers incomplete insight into genome structure and function. For instance, linking a folding pattern to how the genome encodes for a specific cell identity—like a liver, lung, or epithelial cell—has been difficult, said Dr. Imieliński, who is also a member of the Englander Institute for Precision Medicine and the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine. Scientists have theorized that this folding influences gene expression. “But how cell types are encoded, particularly in the structure of DNA, has been a mystery,” he said.
Dr. Imieliski and his research team, which included first author Aditya Deshpande, a recent graduate of the Tri-Institutional Ph.D. Program in Computational Biology & Medicine who worked in Dr. Imieliski’s lab, created a new genome-wide assay and algorithm that allows them to study groups of loci rather than just pairs.
They adapted Hi-C (chromatin conformation capture), a standard approach that evaluates a combination of DNA and protein to assess three-dimensional genome structure, to nanopore sequencing, or the high-throughput sequencing of long, continuous strands of DNA molecules. The new test, named Pore-C, allowed the researchers to examine tens of millions of three-dimensional locus clusters.
They also developed statistical methods to determine which locus groupings were important, based on whether they interacted cooperatively to affect gene expression. “Many three-dimensional interactions of the genome are not important,” Dr. Imieliński said. “Our analytic methods help us prioritize the group interactions that are likely to matter for genome function.” As a key finding of the study, the researchers found that the most significant cooperative groupings of DNA elements occurred around genes associated with cell identity.
Future experiments will explore which specific groupings of genomic components are essential for various aspects of cell identity. The new technology may also help researchers to understand how stem cells, the immature, master cells of the body, differentiate into different cell types.
In addition, researchers may be better able to understand abnormalities in cancer cells. “In the future, this technology may be really helpful in understanding how cancer cell genomes are rearranged, and how those rearrangements drive the altered cell identities that enable cancers to grow and spread,” Dr. Imieliński said.

Uncover the extraordinary story of the Rebbe’s Dollar distribution, a powerful tradition that has transformed lives and inspired acts of kindness across the globe.
The Rebbe’s one-dollar bill, a symbol of charity and compassion, continues to embody the spiritual legacy of Rabbi Menachem Mendel Schneerson, inspiring countless individuals to embrace a life of giving and kindness.
Every Sunday, people from all walks of life – Jews and non-Jews alike – would line up outside the Rebbe’s residence at 770 Eastern Parkway in Brooklyn, New York, eager to receive a dollar bill and a blessing from the Rebbe.
It was a testament to the universal nature of the Rebbe’s message of love, kindness, and the power of good deeds.
The Rebbe would hand out dollar bills to each individual, instructing them to donate the money to a charity of their choice. Through this small act of giving, the Rebbe instilled the value of charity and the potential of a single dollar to create positive change.
The use of lab grown diamonds NZ in jewellery has been growing rapidly over the last few years. This is because they are eco-friendly, and they cost less than mined diamonds. However, it is essential to understand the differences between a lab-grown and a mined diamond before making a purchase decision.
A Lab-Grown Diamond is a synthetic diamond created by humans in a lab instead of being mined from the ground. They are similar to natural diamonds in almost every way, except that they do not cloud or lose their luster over time.
There are several processes that can be used to grow a diamond in a lab, but the most common ones are High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These methods are incredibly complex, but they have the same end goal: to replicate the conditions that naturally occur when a diamond grows on the earth’s surface.
Unlike mined diamonds, formed after millions of years of exposure to extreme heat and temperatures within the earth’s crust, lab-grown diamonds are created by scientists in a controlled environment. This allows them to mimic the same physical and chemical properties of natural diamonds, while also being significantly cheaper and environmentally friendly.
How They’re Made
When a diamond seed is placed inside of a sealed chamber, it is pressurized and heated until the carbon particles break down and crystallize into a fully grown diamond. This process is called growing a diamond in a lab, and many companies have done it since the 1960s.
In addition to being more sustainable, lab-grown diamonds are more ethical than mined diamonds because they don’t heavily impact the environment. For example, a study by Frost & Sullivan found that for each carat of diamonds mined using traditional methods, nearly 100 square feet of land is disturbed and more than 5,798 pounds of mineral waste are created.
Another great thing about lab-grown diamonds is that they don’t consume as much water in the making process. This is because the processes involved in creating a mined diamond require significant amounts of water, and they also create a lot of pollution.
This can lead to many issues, including depleted water supplies and environmental calamities. In addition, the soil can be destroyed, and in turn, the land is rendered unusable once mining operations have ceased.
It is also worth noting that lab-grown diamonds don’t contribute to global warming like mined diamonds, as their carbon is sourced from CO2 emissions. This is a very good thing for the planet, and it is one of the major reasons why people are switching to lab-grown diamonds instead of mined diamonds.
If you want to buy a piece of jewellery with a lab-grown diamond, you’ll need to do some research and make sure that you are getting a good deal on the product. You can do this by checking out prices at different retailers and comparing the costs. You can then choose which option is best for you and your budget.
