Brilliant Bacteria: Programming Bacteria to Make Materials

Brilliant Bacteria: Programming Bacteria to Make Materials

Researchers at Duke have used synthetic biology techniques to engineer bacteria to produce a protein capable of constructing an electronic pressure sensor when supplemented with gold nanoparticles. With a variety of future applications, this technology will diversify how we use microorganisms in biophysical systems.

A Graft that Grows With You: How Grafts Become a Part of Your Heart

A Graft that Grows With You: How Grafts Become a Part of Your Heart

Cardiovascular disease is the leading cause of disease and death in the U.S, yet patients with faulty arteries are forced to deal with synthetic arterial grafts that degrade slowly, prompting further invasive treatment that costs patients, families, and medical personnel time and money. Ramak Khosravi, MD/PhD candidate at Yale, has come up with a method that she hopes will produce a graft that can seamlessly integrate into human bodies.

Silly Bacteria: Tricks are for Kids

Silly Bacteria: Tricks are for Kids

The influence of pathogens, either directly or indirectly, to manipulate vector microbiota for their own benefit, has not been very well described. This study has demonstrated that a pathogen can effectively “trick” vector microbiota and enhance infection. This allows better colonization of the vector.

Insight into Eyesight: Reawakening Retinal Stem Cells

Dr. Bo Chen and his team of researchers at Yale University have figured out a way to activate the stem cell ability of MGs, a special group of glial cells in the retina. Their discovery could someday help restore eyesight to patients whose retinas have been damaged by disease.

Q&A: Three’s a Crowd—How can a baby have three parents?

For parents whose children are at risk of inheriting a mitochondrial disorder, genetic material from a third person can help them conceive a healthy child. Mitochondria are maternally inherited organelles, so if a mother’s mitochondrial DNA is mutated, her children
