A heroic critter squad of gerbils, mice and geckos and other such animals were launched into orbit on Friday, April 19th for beginning a one month Russian experiment for the study of how space travel can affect the living creatures. Scientists assure that this space mission will bring back the animals alive.



The animal astronauts crew launched into the orbit at 6:00AM EDT atop a Soyuz 2 rocket built by Russian that took off from Baikonur Cosmodrome in Kazakhstan. The rocket carried Bion-M1 space capsule that has 15 geckos, 8 Mongolian gerbils, and 45 mice several other species. These are expected to live in orbit for a month, flying 575 kilometers above Earth while the scientists will monitor their health on the ground.

Nicole Rayl, the project manager of NASA's part of the mission, says that there’s been a history of this sort of biological research in the past forty years, and NASA along with Russian side has been working in this area for all this time, which is remarkable. He further added that each mission brings an exceptional focus, be it the specimens being flown or the actual duration of mission.

While the project is being run and supervised by Federal Space Agency of Russia, namely Roscosmos, a panel of scientists from all over the world is also overseeing the many experiments of the mission. Scientists will be monitoring a number of health metrics of animals in space. The spacecraft will transmit information on the animals’ health along with various other conditions in the capsule.




One of the experiments done by NASA focuses on how radiation and microgravity can affect the sperm life in mice. Rayl said that in case humans start visiting other planets on longer flights, it's very important to know if people can reproduce by sex in space. A few missions can really take decades, so reproduction in space could become a necessity.

Other experiments will take the wider view, examining how different systems in body are connected and altered during a spaceflight. The scientists often have keenly targeted experiments where they will closely be examining, say, “functions of cardiovascular system.”

After spending a month in the orbit, Bion-M1 will fall to the ground and scientists will start running tests on the collected animals. While the geckos, gerbils, mice and other species survive their fall through the atmosphere of Earth, scientists will caringly euthanize these animals for getting the data they require.

Technology has become extremely advanced in the past few years. Scientists have been researching on a variety of avenues to make life easier, better and convenient for people. Research is being conducted on various aspects to introduce new technology every day that can prove to be beneficial in the long run. However, it seems that nature seems to beat out all the efforts. What’s your reaction when you see ants crawling? You are probably thinking of getting an ant trap to get rid of them. But, think again because the new research done by scientists has released something very unique about these busy little creatures.


According to the new research, the German insects are able to sense an earthquake even before it hits. The ants can predict an earthquake in advance. It has been discovered by researchers that it is the preference of red wood ants in Germany to build their colonies over active faults as well as fractures where the earth tends to rupture. In Germany, at the University of Duisburg-Essen, Gabriele Berberich asserted that they had noticed a change in the behavior of ants when an earthquake having a magnitude of over 2.0 would strike the area. In addition, he added that the behavior of these ants would not return to normal even a day after the earthquake had passed.

The research was presented by Gabriele Berberich at the annual meeting of the European Geosciences Union that took place in Vienna. Between the years 2009 and 2012, the ants were tracked by Berberich’s team round the clock and they had discovered that there were approximately 15000 ant mounds that were lining the active faults. It was found by the team that it was the habit of the ants to keep on doing their usual activities during daytime, but they would retreat to their mounds as soon as nighttime arrived.

However, Berberich’s team found out that just before an earthquake, the routine of the ants would undergo a noticeable change. The ants tended to remain outside of their mounds even at night and thus stayed awake. They did so despite the fact that this left them vulnerable to other predators of the night. It was further stated in the research that the change in the attitude of the ants only occurred when the earthquake was over the magnitude of 2.0. This is the smallest magnitude of earthquakes that can be felt by human beings.

It is suggested by Berberich that the ants are able to sense the oncoming earthquake through the shifts that take place in the magnetic field of the Earth and also by picking up gas emissions. She said that the red wood ants possessed magneto receptors for sensing electromagnetic fields and also had chemo receptors for identifying the gradients of carbon dioxide. It is still unclear how the ants are able to react to the stimuli and in order to determine it, further research is required. Therefore, Berberich said that they wish to visit more tectonically active areas to see if they react to larger earthquakes.
