Getting vaccinated with oxygen micro-bubbles may be the next big breakthrough in saving lives. When lungs or airways are compromised our bodies brain and major organs shut down because of the lack of oxygen. This condition is called hypoxemia. Current attempts to bypass the lungs have involved attempting to inject oxygen directly into the bloodstream. This has had limited success.
Researchers at Boston Children's Hospital, however, have been experimenting with a new way of delivering oxygen to the blood using microscopic nanobubbles of oxygen encased in a foamy lipid suspension that releases the gas directly when injected like a vaccine. In the image below you can see one of the microscopic nanobubbles in yellow, adjacent to some red blood cells.
So far the test subjects, rabbits with obstructed airways, have remained alive and stable without taking a breath for 15 minutes. The results of this research have been published in the journal, Science Translational Medicine. What does this mean for victims suffering from pneumonia, a heart attack, stroke, asthma, drowning or airway injuries? When administered the microscopic bubble infusion temporarily stops the hypoxemia, which can give a medical trauma team the opportunity to restore airway or lung function. From rabbits to larger animal trials and finally human clinical trials, we may soon see this discovery become a regular part of CPR and emergency medical procedures, saving countless lives.
The current maximum time of use for microscopic nanobubble injections is 30 minutes with serum volume being the limiting factor. The researchers, however, are working on increasing the ratio of microscopic bubbles to fluid to extend the therapy.

Over many centuries, attempts have been made to get food production out of the cities. Produce comes from the land and is transported into the cities. In most western cities, abattoirs have disappeared. Markets are still there, but no longer have a central role in our shopping.
Star Trek Into Darkness: Eye candy for the amygdala. Yes, this is another Hollywood blockbuster depicting a dystopian future with big explosions and small innovations. However, the first ten minutes are worth the price of the ticket. I was pleasantly surprised to see J.J. Abrams using the Ancient Aliens theory and a huge wink to author Zecharia Sitchin's work in the opening scene located on the fictional (depending on who you ask) world of Nibiru.
Spray-on skin. Lab-grown ears. Human tissue grown in a petri dish. We're going deep into sci-fi territory (and it is already happening).
“Extropy” is celebrating its first quarter of a century. The idea was formally introduced as a philosophy of the future in 1988, and many things have happened from the end of the 20th century to the beginning of the 21st century. A new millennium has been born and the philosophy of extropy is well-suited for these new times of accelerating change, full of challenges and opportunities.
One definition of resilience is “the ability to cope with shocks and keep functioning in a satisfying way”. Resilience is about the self organizing capacity of systems. This means the ability to bounce back after disaster, or the ability to transform if a bad stage has happened.
This is my last posting for the next few days. I will be taking my office apart so that we can move to our new apartment downtown next Tuesday. I will be unplugged and disconnected except by tablet. Expect me to be back in the saddle before the end of next week probably in time to provide you with some more headlines. In the interim these are the stories I share with you this week:
