On the International space station in the experiment, the scientists put it on fire a mixture of heptane and isooctane. Such experiments conducted by astronauts to study combustion in microgravity, according to the website of NASA.
Unlike flame on the Ground, on Board the spacecraft torch does not have the form of drops and breaks up into a multitude of fiery balls, which is associated with weak gravity in earth orbit.
The flame formed from igniting the mixture of droplets of heptane and isooctane. Initially, the light from the fire went out, then formed a light blue spherical shell with a diameter of 15 to 20 centimeters around the ignition source.
Inside the sphere then began to appear bright yellow dots formed smoldering soot. Reaches a temperature of two thousand degrees Celsius. Over time, these hot spots are leaving the field and burn out.
In the experiment, the FLEX-2 (Flame Extinguishment Experiment 2) astronauts had to learn how to control fire, including and simmer it on Board the ISS.
Scientists from Canada, China, the UK and the USA estimated the proportion of deaths associated with the pollution of the environment of fine particles (less than 2.5 microns in diameter). A study published in the journal Nature, and briefly about it, reports the University of California, Irvine (USA).
Zoologists from Japan and the UK have studied the aerodynamics of the flight of the mosquito. To do this, they needed to consider in slow motion the movement of an insect in the air. Angled wingspan of a mosquito is only 40 degrees, which is two times less than that of the bees. Study and videos available on the website of Nature.
Scientists from Moscow state University created the first detailed maps of the spatial organization of the genome in mouse cells at early stages of embryo development. For this purpose they used they developed a new approach based on the method Hi-C, which is the fixation of the contacts between DNA sites.
