CRISPR Used Inside a Person’s Body for the First Time Ever

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

Doctors at the Casey Eye Institute at Oregon Health & Science University in Portland have announced the first-ever use of the revolutionary gene editing tool, CRISPR, inside of a person’s body. The tool was used to modify the genes responsible for a particular form of inherited blindness, and those responsible for the pioneering effort say there is real potential here to not only restore the patient’s vision, but open up a new line of medicines specifically used to target and alter DNA.

In an Associated Press report, which comes via NBC, the companies that make the treatment used in the procedure, including Cambridge, Massachusetts-based Editas Medicine and Dublin-based Allergan, highlighted the possibilities moving forward if the trial proves to be successful. Charles Albright, chief scientific officer at Editas, said that “We literally have the potential to take people who are essentially blind and make them see.”

Emerging Trends in Micro- and Nanoscale Technologies in Medicine: From Basic Discoveries to Translation

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

We discuss the state of the art and innovative micro- and nanoscale technologies that are finding niches and opening up new opportunities in medicine, particularly in diagnostic and therapeutic applications. We take the design of point-of-care applications and the capture of circulating tumor cells as illustrative examples of the integration of micro- and nanotechnologies into solutions of diagnostic challenges. We describe several novel nanotechnologies that enable imaging cellular structures and molecular events. In therapeutics, we describe the utilization of micro- and nanotechnologies in applications including drug delivery, tissue engineering, and pharmaceutical development/testing. In addition, we discuss relevant challenges that micro- and nanotechnologies face in achieving cost-effective and widespread clinical implementation as well as forecasted applications of micro- and nanotechnologies in medicine.

DARPA Is Creating a Travel Adapter That Will Be Implanted in Soldiers’ Bodies

Posted by in categories: bioengineering, biotech/medical, food, military

‘Through advances in medical devices and synthetic biology, DARPA’s new Advanced Acclimation and Protection Tool for Environmental Readiness (ADAPTER) program aims to develop a travel adapter for the human body, an implantable or ingestible bioelectronic carrier that can provide warfighters control over their own physiology. The integrated system will be designed to entrain the sleep cycle – either to a new time zone or back to a normal sleep pattern after night missions – and eliminate bacteria that cause traveler’s diarrhea after ingestion of contaminated food and water,’ reads a DARPA statement on the new device.”


The adapter is meant to regulate sleep patterns and protect against diarrhea.

Can Genetic Engineering Bring Back the American Chestnut?

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

The tree helped build industrial America before disease wiped out an estimated three billion or more of them. To revive their lost glory, we may need to embrace tinkering with nature.

New molecular insights into how gut bacteria influences memory

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

New research from an international team of scientists has tracked a compelling series of connections between the gut microbiome and memory. Using a novel mouse model engineered to simulate the genetic diversity of a human population, the study illustrates how genetics can influence memory via bacterial metabolites produced in the gut.

Over the past few years there has been significant research interest in the relationship between memory, cognition and the gut microbiome. While certain families of bacteria that live in our gut have been implicated in memory function, this new study set out to investigate the connection from a different angle, starting with the role genetics play in this relationship.

“To know if a microbial molecule influenced memory, we needed to understand the interaction between genetics and the microbiome,” explains co-corresponding author on the study, Antoine Snijders.

Stanford University lab repurposes scuba gear into reusable PPE

Posted by in categories: bioengineering, biotech/medical

Bioengineering professor Manu Prakash runs a lab at Stanford University that uses low-cost materials to create effective scientific devices. He returned from a recent vacation with some scuba gear — as well as a cold. While he tested negative for COVID-19, he stayed cautious and self-quarantined for two weeks. During that time, he reworked his snorkel mask into a reusable face shield for healthcare providers by combining it with a medical-grade filter. Dubbed the Pneumask, Prakash and his team tested the device and sent their findings to the FDA, which cleared it as a face shield or surgical mask, but not as a respirator. According to The Washington Post, this decision was made so that the masks could go out to healthcare workers immediately, as clearing the device as a respirator would require more time.


Manu Prakash and his team at Stanford University have turned a standard scuba mask into a reusable medical face mask.

Making sense of the viral multiverse

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

In November of 2019—likely, even earlier—a tiny entity measuring just a few hundred billionths of a meter in diameter began to tear apart human society on a global scale. Within a few months, the relentless voyager known as SARS-CoV-2 had made its way to every populated corner of the earth, leaving scientists and health authorities with too many questions and few answers.

Today, researchers are scrambling to understand where and how the novel coronavirus arose, what features account for the puzzling constellation of symptoms it can cause and how the wildfire of transmission may be brought under control. An important part of this quest will involve efforts to properly classify this emergent human pathogen and to understand how it relates to other we may know more about.

In a consensus statement, Arvind Varsani, a molecular virologist with ASU’s Biodesign Center for Fundamental and Applied Microbiomics and a host of international collaborators propose a new classification system, capable of situating coronaviruses like SARS-CoV-2 within the enormous web of viruses across the planet, known as the virosphere.

Why synthetic biology is about much more than resurrecting woolly mammoths

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

Synthetic biology has been described as a kind of “genetic engineering on steroids”.


Synthetic biology …Simply mentioning this term — whether at a cocktail party or on a pop culture TV show — evokes a plethora of responses. These could range from puzzled looks to questions about the somewhat famous, though likely quixotic, quest to resurrect a woolly mammoth from remnants recovered in Siberia. Also, on the radar screen is synthetic biology as applied to the development of drugs and biological weapons. But flying below the radar — and, oddly, the sweet spot for investments by governments and private industry — is a less sexy focus on the industrial uses of synthetic biology. Such uses range from environmental clean-ups to new energy sources.
