Lab-grown Blood Stem Cells

Growing blood stem cells in a lab may be the key to producing a limitless supply of blood. This has potential to bypass the difficult process of finding a matching donor and doing blood marrow transplants. Limitless Lab-Grown Blood Is ‘Tantalizingly Close’ After 20 Years – [singularityhub.com] Blood stem cells are things of wonder: hidden […]

Stem Cell Nano-mesh Regenerates Tendons

A polymer mesh fabric seeded with stem cells can help in the regeneration of rotator cuff tendons. Stem Cell Fabric Innovation Regrows Rotator Cuffs – [uconn.edu] The combination of the “nano-mesh” with stem cells seems to be critical. Surgeons will sometimes inject stem cells into rotator cuff repairs, but results from this technique are mixed. […]

Smart Wound Stitches Collect Data

The use of smart thread in wound sutures (stitches) allows them to wirelessly collect data that can help doctors diagnose the healing process. Researchers invent “smart” thread that collects diagnostic data when sutured into tissue – [tufts.edu] For the first time, researchers led by Tufts University engineers have integrated nano-scale sensors, electronics and microfluidics into […]

3D Printing Stem Cell Bio-Ink

3D printing accumulates finely articulated layers to create complex three dimensional objects by extruding the material through jets, like ink-jet printers. Stem cells have shown tremendous potential to regenerate and replace tissues in human bodies. Using a polymer extracted from seaweed, researchers have created a “bio-ink” that contains stem cells and can be used in […]

Gel Grows New Blood Vessels in Rats

An injectable gel that has shown results in growing new blood vessels in rats is now being developed in pre-clinical trials at the University of Texas. If this therapy can be moved forward into human trials, it is hoped it will be useful for treating the deterioration of blood vessels in diabetics. Regenerating Blood Vessels […]

Fasting Diet Mimics Genetic Disease Protection

Laron Syndrome is a genetic disorder that causes low levels of a growth hormone known as IGF-1. High levels of IGF-1 have been linked to cancer, diabetes and other diseases, while low levels seem to protect against them. There is a growing pool of evidence that various forms of intermittent fasting can also produce lower […]

Fixing Brains With Engineered Neural Tissue

Micro Tissue Engineered Neural Networks (micro-TENNs) are preformed neural network structures which can serve as a foundation for reconstruction of damaged brain pathways. These engineered tissues are being injected into the brains of lab rats for testing. If the neural network tissue is “trained” with a specific knowledge set before being injected, it might become […]

Teixobactin, the First New Antibiotic Class in 28 Years

In 1928, Alexander Fleming discovered that penicillin has the ability to kill many disease causing bacteria, creating a new kind of medication known as antibiotics. Over the years since then, many variations of penicillin have been discovered and other groups or “classes” of antibiotics have also been found. Each class of antibiotics continues to be […]

BioHacking and Security

Homebrew bio-hacking kits will enable bio-terrorism and change the face of security requirements. Once, genetic engineering required big expensive laboratory environments. A cheap kit won’t make you an instant genetic engineering expert but it can start you down the path to understanding how it works. Homebrew chemistry, electronics, and computer kits have sparked interest and […]

Soldier, Heal Thyself

An old proverb, “Cura te ipsum” (Latin), means “Physician, heal thyself”. DARPA is beginning work on a project that will enhance the ability of the human body to heal itself. The project will focus first on mapping the neural pathways involved in disease and injury and then on investigating the potential of modulating nerve activity […]
