When scientists discovered DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Houston, TX — Oct 8, 2020 - In a letter published today in the New England Journal of Medicine, a team of physicians from Baylor College of Medicine, Texas Children’s Hospital, and the University of California, San Francisco, describe a remarkable case of a Type 1 diabetes (T1D) patient, who no longer needs insulin to maintain optimal blood sugar levels. The physicians employed a precision/personalized medicine approach to specifically target the underlying genetic mutation, which was the primary driver of this patient’s diabetes.

“To the best of our knowledge, this is the first example of a T1D patient who has experienced a complete reversal of insulin-dependence and we are excited by the prospect that that could be a viable therapeutic strategy for a subset of T1D patients” said corresponding author Dr. Lisa R. Forbes, deputy director for clinical services and community outreach for the Texas Children’s William T. Shearer Center for Human Immunobiology and assistant professor of Pediatrics, Immunology, Allergy and Retrovirology at Baylor.

T1D is a chronic condition in which the pancreas produces little to no insulin, a hormone that maintains sugar levels in the blood. Currently, the treatment options available to T1D patients consist of managing blood sugar levels with insulin, diet and exercise to prevent further complications.

A man with terminal heart disease is responding well three days after being given a genetically modified pig heart in a first-of-its-kind surgery, his doctors reported on Monday.
The surgery, performed by a team at the University of Maryland Medicine in the United States, is among the first to demonstrate the feasibility of a pig-to-human heart transplant, a field made possible by new gene editing tools.
If proven successful, scientists hope pig organs could help alleviate shortages of donor organs.
For David Bennett, a 57-year-old from Maryland, the heart transplant was his last option.

I am happy to say that my recently published computational COVID-19 research has been featured in a major news article by HPCwire! I led this research as CTO of Conduit. My team utilized one of the world’s top supercomputers (Frontera) to study the mechanisms by which the coronavirus’s M proteins and E proteins facilitate budding, an understudied part of the SARS-CoV-2 life cycle. Our results may provide the foundation for new ways of designing antiviral treatments which interfere with budding. Thank you to Ryan Robinson (Conduit’s CEO) and my computational team: Ankush Singhal, Shafat M., David Hill, Jr., Tamer Elkholy, Kayode Ezike, and Ricky Williams.


Conduit, created by MIT graduate (and current CEO) Ryan Robinson, was founded in 2017. But it might not have been until a few years later, when the pandemic started, that Conduit may have found its true calling. While Conduit €™s commercial division is busy developing a Covid-19 test called nanoSPLASH, its nonprofit arm was granted access to one of the most powerful supercomputers in the world €”Frontera, at the Texas Advanced Computing Center (TACC) €”to model the €œbudding € process of SARS-CoV-2.

Budding, the researchers explained, is how the virus €™ genetic material is encapsulated in a spherical envelope €”and the process is key to the virus €™ ability to infect. Despite that, they say, it has hitherto been poorly understood:

The Conduit team €”comprised of Logan Thrasher Collins (CTO of Conduit), Tamer Elkholy, Shafat Mubin, David Hill, Ricky Williams, Kayode Ezike and Ankush Singhal €”sought to change that, applying for an allocation from the White House-led Covid-19 High-Performance Computing Consortium to model the budding process on a supercomputer.

It depends.

Warp drive. Site-to-site transporter technology. A vast network of interstellar wormholes that take us to bountiful alien worlds. Beyond a hefty holiday wish-list, the ideas presented to us in sci-fi franchises like Gene Roddenberry’s “Star Trek” have inspired countless millions to dream of a time when humans have used technology to rise above the everyday limits of nature, and explore the universe.

But to guarantee the shortest path to turning at least some of these ideas into genuine scientific breakthroughs, we need to push ideas like general relativity to the breaking point. Tractor beams, one of the most exotic ideas proposed by the genre that involves manipulating space-time to pull or push objects at a distance, take us beyond the everyday paradigm of science, to the very edge of theoretical physics. And, a team of scientists examined how they might work in a recent study shared on a preprint server.

“In researching sci-fi ideas like tractor beams, the goal is to push and try to find a demarcation point where something more is needed, like quantum gravity,” said Sebastian Schuster, a scientist with a doctorate in mathematical physics from the Charles University of Prague, in an interview with IE. And, in finding out if tractor beams can work, we might also uncover even more exotic forces, like quantum gravity. So strap in.

The company is developing novel therapeutics targeting aging in humans and dogs by using genetically modified adeno-associated virus (AAV) vectors to deliver copies of the SIRT6 gene variant found in centenarians. SIRT6 has already been shown to have significant capabilities to repair DNA damage, and Genflow’s aim is to show that it can also improve healthspan and, potentially, increase lifespan. “Our business model is to develop our lead compound, GF-1002, that has already yielded encouraging pre-clinical results,” Leire told us. “We are currently undertaking pre-clinical trials which are expected to take approximately two years.


SIRT6 targeting longevity biotech announces intention to float on the London Stock Exchange, with IPO later this month.

Sinclair’s first episode. Enjoy.


In this episode, Dr. David Sinclair and co-host Matthew LaPlante discuss why we age. In doing so, they discuss organisms that have extreme longevity, the genes that control aging (mTOR, AMPK, Sirtuins), the role of sirtuin proteins as epigenetic regulators of aging, the process of “ex-differentiation” in which cells begin to lose their identity, and how all of this makes up the “Information Theory of Aging”, and the difference between “biological age” and “chronological age” and how we can measure biological age through DNA methylation clocks.
