A new class of sound wave has been developed for the first time in 50 years that could revolutionize the use of stem cells in medical treatments.
This new class can be used as a “supervaccine” that can deliver vaccines and other medicines directly to the lungs in record time.
Dr Millers paper here hits the nail on the head for me about aging research and how we can speed it up.
“The time spent by gerontologists debating whether aging is a single process or many would be better devoted to trying to figure out the mechanistic links between the master clock whose existence is strongly suggested by the unitarian argument and the many cell-specific, organ-specific, and organism-wide processes that march in crude synchrony at species-specific rates.”
Yes! This is exactly the attitude to take. Too much debate and argument instead of buckling down and getting the research done to prove or disprove aging hypotheses. Cut to the chase and lets just do it.
Analyzing expressions is an increasingly hot topic among tech companies.
It’s not clear what it plans to do with it yet, but Apple has gobbled up a startup whose technology can read facial expressions.
The tech giant has reportedly acquired Emotient, a San Diego-based company that uses artificial technology to detect emotion from facial expressions, Apple confirmed to The Wall Street Journal. The company’s technology has primarily been used by advertisers, doctors, and retailers, though it’s not clear what Apple AAPL 0.66% plans to do with it.
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.

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.
