The Academy evacuated more than 600 families and 110 dormitory residents from the base the evening of June 27.

YF-12A makes a low pass.
Caption reads:
EDWARDS AIR FORCE BASE, Calif., Sept. 30—NEW INTERDEPTOR PUTS ON SHOW—The Air Force’s speedy new interceptor, the YF12A, flashes across Edwards Air Force Base, Calif., today in a low-level pass during the first public demonstration of the plane. The plane was flown at low speeds, in contrast to the better than 2000-miles-per-hour capability.

Boston Scientists Invent Particles That Allow Humans to Live Without Breathing



The invention, developed by a team at Boston Children’s Hospital, will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure.This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient.


The solution has already been successfully tested on animals under critical lung failure. When the doctors injected this liquid into the patient’s veins, it restored oxygen in their blood to near-normal levels, granting them those precious additional minutes of life.


The particles are composed of oxygen gas pocketed in a layer of lipids, a natural molecule that usually stores energy or serves as a component to cell membranes. Lipids can be waxes, some vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, or—as in this case—fats.


These fatty oxygen particles are about two to four micrometers in size. They are suspended in a liquid solution that can be easily carried and used by paramedics, emergency crews and intensive care personnel. This seemingly magic elixir carries “three to four times the oxygen content of our own red blood cells.”


Similar solutions have failed in the past because they caused gas embolism, rather than oxygenating the cells. According to John Kheir, MD at the Department of Cardiology at Boston Children’s Hospital, they solved the problem by using deformable particles, rather than bubbles.


“We have engineered around this problem by packaging the gas into small, deformable particles. They dramatically increase the surface area for gas exchange and are able to squeeze through capillaries where free gas would get stuck.”

Paris in June. Some come for the shopping, the museums, the sidewalk cafes, the romantic evening strolls through the city of light. And then there’s the crowd that’s jonesing for the hangar-and-asphalt vibe of Eurosatory, the massive biannual military bazaar that sprawls over the exhibition grounds near Charles de Gaulle airport. The exhibition is designed to be a showcase for European land systems companies, but it is also the best hands-on venue for the latest technology and innovations in Israel’s often-secretive defense industry.
