I got a chip implanted in a biohacking garage

Posted by in categories: bioengineering, biological, cyborgs, food, genetics, health, neuroscience

In the underground movement known as, people are taking their health into their own hands. Biohacking ranges from people making simple lifestyle changes to extreme body modifications.

One popular form of focuses on nutrigenomics, where biohackers study how the foods they eat affect their genes over time. They believe they can map and track the way their diet affects genetic function. They use dietary restrictions and blood tests, while tracking their moods, energy levels, behaviors, and cognitive abilities.

Genetically modified mice pave the way for customized medicine in a rare disease

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

An international research team led by Dr. Ana Guadaño at the Alberto Sols Biomedical Research Institute (IIBM, a combined CSIC-UAM center) and involving the Complutense University of Madrid (UCM), used CRISPR gene editing techniques to incorporate into mice a mutation of the MCT8 protein responsible for transporting thyroid hormones to the interior of the cell.

Patients with mutations in this protein suffer from Allan-Herndon-Dudley syndrome, a that takes the form of serious neurological alterations, in which each patient may reveal a different mutation of MCT8.

This study, published in Neurobiology of Disease, describes the first avatar model for the disease—in other words, the first animal model with the same as various .

Hugo de Garis — From Nanotech to Femtotech — There’s Plenty More Room at the Bottom

Posted by in categories: bioengineering, biotech/medical, genetics, information science, nanotechnology, robotics/AI

Discusses the possibility of Femtotech and the technological possibilities it may unlock. Not long ago nanotechnology was a fringe topic; now it’s a flourishing engineering field, and fairly mainstream. For example, while writing this article, I happened to receive an email advertisement for the “Second World Conference on Nanomedicine and Drug Delivery,” in Kerala, India. It wasn’t so long ago that nanomedicine seemed merely a flicker in the eyes of Robert Freitas and a few other visionaries!

But nano is not as small as the world goes. A nanometer is 10–9 meters – the scale of atoms and molecules. A water molecule is a bit less than one nanometer long, and a germ is around a thousand nanometers across. On the other hand, a proton has a diameter of a couple femtometers – where a femtometer, at 10–15 meters, makes a nanometer seem positively gargantuan. Now that the viability of nanotech is widely accepted (in spite of some ongoing heated debates about the details), it’s time to ask: what about femtotech? Picotech or other technologies at the scales between nano and femto seem relatively uninteresting, because we don’t know any basic constituents of matter that exist at those scales. But femtotech, based on engineering structures from subatomic particles, makes perfect conceptual sense, though it’s certainly difficult given current technology.

Editing out HIV: application of gene editing technology to achieve functional cure

Posted by in categories: bioengineering, biotech/medical

face_with_colon_three year 2021.


Highly active antiretroviral therapy (HAART) successfully suppresses human immunodeficiency virus (HIV) replication and improves the quality of life of patients living with HIV. However, current HAART does not eradicate HIV infection because an HIV reservoir is established in latently infected cells and is not recognized by the immune system. The successful curative treatment of the Berlin and London patients following bone marrow transplantation inspired researchers to identify an approach for the functional cure of HIV. As a promising technology, gene editing-based strategies have attracted considerable attention and sparked much debate. Herein, we discuss the development of different gene editing strategies in the functional cure of HIV and highlight the potential for clinical applications prospects. Graphical Abstract.

The CRISPR Apostle: Rodolphe Barrangou

Posted by in categories: bioengineering, biotech/medical, drones, food, genetics, health

http://www.iBiology.org.

For millennia, humans have been harnessing #microbes to produce everything from breads, to cheeses, to alcohol. Now these tiny organisms have produced another powerful revolution — the gene editing tool CRISPR. Rodolphe Barrangou, Ph.D., was working at the food company Danisco, where he was trying to produce yogurt lines resistant to contamination. In a series of groundbreaking experiments, he helped uncover what CRISPR was, how it worked, and why it could be so transformative.

How to edit the genes of nature’s master manipulators

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

CRISPR, the Nobel Prize-winning gene editing technology, is poised to have a profound impact on the fields of microbiology and medicine yet again.

A team led by CRISPR pioneer Jennifer Doudna and her longtime collaborator Jill Banfield has developed a clever tool to edit the genomes of bacteria-infecting viruses called bacteriophages using a rare form of CRISPR. The ability to easily engineer custom-designed —which has long eluded the —could help researchers control microbiomes without antibiotics or harsh chemicals, and treat dangerous drug-resistant infections. A paper describing the work was recently published in Nature Microbiology.

“Bacteriophages are some of the most abundant and diverse biological entities on Earth. Unlike prior approaches, this editing strategy works against the tremendous genetic diversity of bacteriophages,” said first author Benjamin Adler, a postdoctoral fellow in Doudna’s lab. “There are so many exciting directions here—discovery is literally at our fingertips.”

Biomembrane research findings could advance understanding of computing and human memory

Posted by in categories: bioengineering, biological, computing, health, nanotechnology

While studying how bio-inspired materials might inform the design of next-generation computers, scientists at the Department of Energy’s Oak Ridge National Laboratory achieved a first-of-its-kind result that could have big implications for both edge computing and human health.

Results published in Proceedings of the National Academy of Sciences show that an artificial is capable of long-term potentiation, or LTP, a hallmark of biological learning and . This is the first evidence that a cell membrane alone—without proteins or other biomolecules embedded within it—is capable of LTP that persists for many hours. It is also the first identified nanoscale structure in which memory can be encoded.

“When facilities were shut down as a result of COVID, this led us to pivot away from our usual membrane research,” said John Katsaras, a biophysicist in ORNL’s Neutron Sciences Directorate specializing in neutron scattering and the study of biological membranes at ORNL.
