Yelling at stem cells.

Acoustics experts have created a new class of sound wave — the first in more than half a century — in a breakthrough they hope could lead to a revolution in stem cell therapy.

The team at RMIT University in Melbourne, Australia, combined two different types of acoustic sound waves called bulk waves and surface waves to create a new hybrid: “surface reflected bulk waves”.

Johnny Matheny is the first person to attach a mind-controlled prosthetic limb directly to his skeleton. After losing his arm to cancer in 2008, Johnny signed up for a number of experimental surgeries to prepare himself to use a DARPA-funded prosthetic prototype. The Modular Prosthetic Limb, developed by the Johns Hopkins Applied Physics Laboratory, allows Johnny to regain almost complete range of motion through the Bluetooth-controlled arm.

And the Singularity rolls ever on. And on.

An advanced “molecular prosthetic” — a cell with synthetic gene circuits that can be implanted into an organism to take over metabolic functions that the organism cannot perform itself — has been developed by ETH Zurich scientists.

Moximed, a firm with offices in Hayward, California and Zurich, Switzerland, recently won the European CE Mark to introduce its Atlas Knee System. We just got hold of photos of the Atlas and more information on how it works. The device is a knee joint unloader designed to reduce the pressure applied to the joint and to push off the eventual need for a knee replacement. The device works like the shock absorbers in your car, but instead for the knee. It results in less damage to the cartilage within the knee, letting it last longer than it would naturally without the support of the Atlas.

The company hopes the device will allow patients to maintain an active lifestyle they’re used to while improving satisfaction, reducing repeat surgeries, and lowering pain.

From the announcement:

We may be fed a tale of ever expanding life expectancy, but while average lifespans may be rising maximum years are unchanged. If we want to keep extending the clock we need more than antibiotics and nutrition.

The easy work is done

While improving living standards and reducing infant mortality was not an easy job in itself, it extended years without fundamentally changing human biology. The incredible changes brought by the 20th century yielded longevity — but predominantly did so by lifting the majority closer to those luckier few. Even in the ancient world individuals seemingly lived over 80 years old; it was simply a rarer event to do so. You were significantly more likely to be felled by a disease beforehand, and many never reached such an advanced age as a result.

Patients needing surgery to reconstruct body parts such as noses and ears could soon have treatment using cartilage which has been grown in a lab.

The process involves growing someone’s cells in an incubator and then mixing them with a liquid which is 3D printed into the jelly-like shape needed.

It is then put back in an incubator to grow again until it is ready.

Three research groups, working independently of one another, reported in the journal Science on Thursday that they had used the Crispr-Cas9 technique to treat mice with a defective dystrophin gene. Each group loaded the DNA-cutting system onto a virus that infected the mice’s muscle cells, and excised from the gene a defective stretch of DNA known as an exon.

Without the defective exon, the muscle cells made a shortened dystrophin protein that was nonetheless functional, giving all of the mice more strength.

The teams were led by Charles A. Gersbach of Duke University, Eric N. Olson of the University of Texas Southwestern Medical Center and Amy J. Wagers of Harvard University.
