Korea: Researchers 3D Printing Tracheas with Epithelial Cells & Chondrocytes

Posted by in categories: 3D printing, bioprinting, biotech/medical

Korean researchers have been experimenting further in the bioprinting of tracheal implants, publishing recent results in ‘Trachea with Autologous Epithelial Cells and Chondrocytes.’ The team of scientists details their use of polycaprolactone and hydrogel mixed with nasal epithelial and auricular cartilage cells.

After bioprinting an artificial trachea with these materials and tissue, they transplanted them into 15 rabbits, six of which were a control group. The goal was to find a way to overcome tracheal problems due to tumors, the most common of which are adenoid cystic carcinomas and squamous cell carcinomas. Previously there have been substantial challenges in creating viable tracheas that are anatomically correct and can produce a ciliated epithelium. Issues have arisen with infection, implants that become dislodged, have migrated, or experienced obstruction.

New milestones in helping prevent eye disease with Verily

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

Over the last three years, Google and Verily—Alphabet’s life sciences and healthcare arm—have developed a machine learning algorithm to make it easier to screen for disease, as well as expand access to screening for DR and DME. As part of this effort, we’ve conducted a global clinical research program with a focus on India. Today, we’re sharing that the first real world clinical use of the algorithm is underway at the Aravind Eye Hospital in Madurai, India.


Google and Verily share updates to their initiative to diagnose diabetic eye disease leveraging machine learning.

A newly discovered stem cell that keeps bones growing

Posted by in category: biotech/medical

Bone elongation requires the maintenance of a growth plate of cartilage. Two studies have now identified stem cells specific to this structure that give rise to both cartilage cells and bone-marrow stem cells. Identification of a stem cell that promotes the growth of long bones.

Researchers move closer to practical photonic quantum computing

Posted by in categories: biotech/medical, computing, quantum physics

For the first time, researchers have demonstrated a way to map and measure large-scale photonic quantum correlation with single-photon sensitivity. The ability to measure thousands of instances of quantum correlation is critical for making photon-based quantum computing practical.

In Optica, The Optica l Society’s journal for high impact research, a multi-institutional group of researchers reports the new measurement technique, which is called correlation on spatially-mapped photon-level image (COSPLI). They also developed a way to detect signals from single photons and their correlations in tens of millions of images.

“COSPLI has the potential to become a versatile solution for performing quantum particle measurements in large-scale photonic quantum computers,” said the research team leader Xian-Min Jin, from Shanghai Jiao Tong University, China. “This unique approach would also be useful for quantum simulation, quantum communication, quantum sensing and biomedical imaging.”

Poll: Two Thirds of Americans Support Human Gene Editing to Cure Disease

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

Questions about using technologies like CRISPR to gene edit human embryos gained immediacy last month, when Chinese scientists claimed to have edited the genes of two babies in order to protect them against HIV — a move that prompted an international outcry, but also questions about when the technology will be ready for human testing.

“People appear to realize there’s a major question of how we should oversee and monitor use of this technology if and when it becomes available,” Columbia University bioethicist Robert Klitzman told the AP of the new research. “What is safe enough? And who will determine that? The government? Or clinicians who say, ‘Look, we did it in Country X a few times and it seems to be effective.

Chemists Grew A “Synthetic Brain” That Stores Memories in Silver

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

“It’s dangerous to directly correlate things like, ‘This is a brain!’” Gimzewski told ZDNet. “It’s exhibiting electrical characteristics which are very similar to a functional MRI of brains, similar to the electric characteristics of neuronal cultures, and also EEG patterns.”

Rare ‘semi-identical’ twins discovered during Australian woman’s pregnancy

Posted by in category: biotech/medical

A rare set of semi-identical twins – only the second set ever reported in the world – have been identified in Australia.

The now 4-year-old boy and girl from Brisbane share all of their mother’s DNA but only a part of their father’s DNA, making them identical on their mother’s side but fraternal on their father’s, a statement detailing the discovery said.

This was also the first time semi-identical twins have been identified during pregnancy, according to a case report recently published in the New England Journal of Medicine.

Boosting Cellular Housekeeping with Exercise and Fasting

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

In order to remain healthy and functional, cells have a number of maintenance systems that help them to dispose of metabolic waste and unwanted proteins. Autophagy is perhaps the best-known example of how cells purge their waste, and another is the ubiquitin-proteasome system (UPS). Researchers are working on ways to boost the activity of the UPS to improve cellular health.

The ubiquitin-proteasome system

During normal cellular function, proteins being constructed in the cell can sometimes become misfolded and start to accumulate over time, which can cause the cell to become dysfunctional and encourage diseases such as Alzheimer’s to develop as the system gums up with bent and broken proteins.
