EARD 2023 Panel Discussion: Is Aging Truly Reversible?

Posted by in categories: bioengineering, neuroscience, quantum physics

A nice talk. At 18 minutes dude says healthspan is way more important than lifespan. Never mind that large sign behind him that says lifespan. But, not to knock it too much, yes healthspan is important too.


Dr. Oliver Medvedik, Dr. Aubrey de Grey, Dr. Peter Fedichev, Dr. Hanadie Yousef, Reason, and Dr. Hans Keirstead debate whether or not aging is truly reversible at the Longevity+DeSci Summit NYC (EARD 2023). \

A global dataset of pandemic- and epidemic-prone disease outbreaks

Posted by in categories: bioengineering, biotech/medical, genetics, nanotechnology

I believe nanomachines or new advanced rna antivirals that can target one’s own variants of viruses will be game changers to prevent future global pandemics. Also eventually new genetic engineering could allow for the end to all viruses with some sorta Omni vaccine.


Measurement(s) Pandemic-and epidemic-prone disease outbreaks Technology Type(s) Text mining using R Sample Characteristic — Organism Disease outbreaks Sample Characteristic — Environment spatiotemporal region Sample Characteristic — Location Global.

Why ‘resurrection biology’ is gaining traction around the world

Posted by in categories: bioengineering, biotech/medical, existential risks, genetics

Resurrection biology — attempting to bring strings of molecules and more complex organisms back to life — is gaining traction in labs around the world.

The work is a far cry from the genetically engineered dinosaurs that escape in the blockbuster movie “Jurassic Park,” although for some scientists the ultimate goal is de-extinction and resurrecting animals and plants that have been lost.

Other researchers are looking to the past for new sources of drugs or to sound an alarm about the possibility of long-dormant pathogens. The field of study is also about recreating elements of human history in an attempt to better understand how our ancestors might have lived and died.

Bioengineers building the intersection of organoids and AI with ‘Brainoware’

Posted by in categories: bioengineering, biotech/medical, robotics/AI

Feng Guo, an associate professor of intelligent systems engineering at the Indiana University Luddy School of Informatics, Computing and Engineering, is addressing the technical limitations of artificial intelligence computing hardware by developing a new hybrid computing system—which has been dubbed “Brainoware”—that combines electronic hardware with human brain organoids.

Advanced AI techniques, such as and , which are powered by specialized silicon computer chips, expend enormous amounts of energy. As such, engineers have designed neuromorphic computing systems, modeled after the structure and function of a human brain, to improve the performance and efficiency of these technologies. However, these systems are still limited in their ability to fully mimic brain function, as most are built on digital electronic principles.

In response, Guo and a team of IU researchers, including graduate student Hongwei Cai, have developed a hybrid neuromorphic computing system that mounts a brain organoid onto a multielectrode assay to receive and send information. The brain organoids are brain-like 3D cell cultures derived from and characterized by different brain cell types, including neurons and glia, and brain-like structures such as ventricular zones.

This first CRISPR gene-editing treatment is just the beginning. Here’s what’s coming next

Posted by in categories: bioengineering, biotech/medical, chemistry, food, genetics, robotics/AI

2023 was the year that CRISPR gene-editing sliced its way out of the lab and into the public consciousness—and American medical system. The Food and Drug Administration recently approved the first gene-editing CRISPR therapy, Casgevy (or exa-cel), a treatment from CRISPR Therapeutics and partner Vertex for patients with sickle cell disease. This comes on the heels of a similar green light by U.K. regulators in a historic moment for a gene-editing technology whose foundations were laid back in the 1980s, eventually resulting in a 2020 Nobel Prize in Chemistry for pioneering CRISPR scientists Jennifer Doudna and Emmanuelle Charpentier.

That decades-long gap between initial scientific spark, widespread academic recognition, and now the market entry of a potential cure for blood disorders like sickle cell disease that afflict hundreds of thousands of people around the world is telling. If past is prologue, even newer CRISPR gene-editing approaches being studied today have the potential to treat diseases ranging from cancer and muscular dystrophy to heart disease, birth more resilient livestock and plants that can grapple with climate change and new strains of deadly viruses, and even upend the energy industry by tweaking bacterial DNA to create more efficient biofuels in future decades. And novel uses of CRISPR, with assists from other technologies like artificial intelligence, might fuel even more precise, targeted gene-editing—in turn accelerating future discovery with implications for just about any industry that relies on biological material, from medicine to agriculture to energy.

With new CRISPR discoveries guided by AI, specifically, we can expand the toolbox available for gene editing, which is crucial for therapeutic, diagnostic, and research applications… but also a great way to better understand the vast diversity of microbial defense mechanisms, said Feng Zhang, another CRISPR pioneer, molecular biologist, and core member at the Broad Institute of MIT and Harvard in an emailed statement to Fast Company.

New, DNA-Dependent Gene Editing Technology Could Shift the Paradigm of Precise Editing

Posted by in categories: bioengineering, biotech/medical, chemistry

For instance, the pegRNA molecules used in prime editing are difficult and expensive to chemically synthesise or laborious to clone, which hampers the crucial optimisation of prime-editing efficiency. Additionally, the reverse transcriptase (RT) enzymes used in prime editing are relatively error-prone and have low processivity, which may limit the precision and size of edits that can be introduced. Furthermore, RTs have a low affinity for dNTPs, which can impact prime-editing efficiency in non-dividing and differentiated cells.

To address these issues, two research groups led by Dr. Ben Kleinstiver at Mass General Hospital (MGH) & Harvard Medical School, and Dr. Erik Sontheimer at the RNA Therapeutics Institute (UMass Chan Medical School) have independently developed new approaches that build upon prime editing by replacing RT with another type of enzyme, namely a DNA-dependent DNA polymerase. This change permits the use of DNA instead of RNA as a template for editing, potentially addressing some of the main limitations of prime editing by allowing higher efficiency and adaptability.
