Could deafness be reversed? Scientists re-grow damaged hair cells that have been killed off by age or noise inside the ear…
Researchers from the University of Rochester found that viruses, genetics and even existing drugs could cause little hairs to regrow in the inner ear. These hairs pick up on noises entering the ear.
Earlier this year, we hosted the Ending Age-Related Diseases 2018 conference at the Cooper Union, New York City. This conference was designed to bring together the best in the aging research and biotech investment worlds and saw a range of industry experts sharing their insights.
Joe Betts Lacroix of Y Combinator and Vium discusses the different ways in which entrepreneurs can focus on overcoming the diseases of aging, namely direct, indirect, and money-first approaches, and the strengths and weakness of each.
Joe was the primary technical founder of hardware/software startup OQO, which entered the Guinness Book of World Records for building the smallest fully featured PC. His experience spans from biotech research to electronics design. Very experienced in invention, prosecution and monetization of intellectual property, he has over 80 patents granted and pending in fields ranging from biophysics and safety systems to antennas, thermal systems, user interfaces, and analog electronics. He has written numerous peer-reviewed publications in fields such as biophysics, genetics, electronics, and robotics. Joe holds a Harvard A.B., an MIT S.M. and a Caltech research fellowship.
Researchers healed mice with a genetic metabolic disorder that also affects humans by using a new editing tool to target and correct genetic mutations.
Some babies are born with the metabolic disorder phenylketonuria and need a special diet so that the amino acid phenylalanine doesn’t accumulate in the body. Excess phenylalanine delays mental and motor development. If left untreated, the children may develop mental disabilities.
The cause of this metabolic disorder is a mutation in a gene that provides the blueprint for the enzyme phenylalanine hydroxylase (Pah). The enzyme, which is produced by the cells of the liver, metabolizes phenylalanine.
A team of Tufts University-led researchers has developed three-dimensional (3D) human tissue culture models for the central nervous system that mimic structural and functional features of the brain and demonstrate neural activity sustained over a period of many months. With the ability to populate a 3D matrix of silk protein and collagen with cells from patients with Alzheimer’s disease, Parkinson’s disease, and other conditions, the tissue models allow for the exploration of cell interactions, disease progression and response to treatment. The development and characterization of the models are reported today in ACS Biomaterials Science & Engineering, a journal of the American Chemical Society.
The new 3D brain tissue models overcome a key challenge of previous models –the availability of human source neurons. This is due to the fact that neurological tissues are rarely removed from healthy patients and are usually only available post-mortem from diseased patients. The 3D tissue models are instead populated with human induced pluripotent stem cells (iPSCs) that can be derived from many sources, including patient skin. The iPSCs are generated by turning back the clock on cell development to their embryonic-like precursors. They can then be dialed forward again to any cell type, including neurons.
The 3D brain tissue models were the result of a collaborative effort between engineering and the medical sciences and included researchers from Tufts University School of Engineering, Tufts University School of Medicine, the Sackler School of Graduate Biomedical Sciences at Tufts, and the Jackson Laboratory.
Michael Schein: How did you end up working at the forefront of biology and technology?
Andrew Hessel: I have the strangest career ever. I originally got into the life sciences simply because all the other areas of technology just weren’t that interesting to me. Most technology falls apart and ends up in the junkyard. Cars rust. Even buildings can burn down. But biotech is different because even though organisms die, DNA gets passes on. Unfortunately, as I quickly learned, most scientists make really crappy money. So I thought: Let me find a way to pursue what I’m interested in but in a way that lets me make a good living. With that in mind, I’ve detoured into a medley of different technology companies. Eventually I made my way to work that’s at the intersection of biological research and computers. That’s how I ended up doing what I do now.
Schein: Tell us about the specific kind of biotech that takes up most of your headspace these days.
