Genetic engineering has shown the connection between the fins and hand The technology of gene editing is a useful topic in medicine. Most genetic engineering is still associated with conventional medical practice, at least so it turns out. Scientists from the University of Chicago used CRISPR to identify key evolutionary relationship between the fin and the arm. The researchers altered the genes of fish-zebras, which are responsible for the fins so that certain cells began to glow. Further, they found after observi...
Science has taken the first steps toward artificial uterus The first 13 days after conception, still remain a mystery to science. Hormone levels are too low to register a positive result of a possible test, but scientists simply do not have any methods of analysis at this stage of fetal development. If scientists do not know and can not determine the moment of conception, then they are not able to observe the development of the embryo the first two weeks. Science, of course, researched the process of de...
How does a long trip in space on the brain activity of a person? In the period of the future mission to Mars, astronauts will have to leave the protective magnetic field of the Earth. As such anti protective the procedure will affect their brain activity? When they go into deep Space high-energy cosmic rays would flash the case of the space suit and easily get to the organs of the body. It may cause irreparable harm to the health of astronauts who will go to conquer the Red planet.

Doctors managed to return the sensitivity of the patient`s arm using a new type of prosthesis 10 years ago Nathan Copeland was in an accident, with the result that his motor functions were partially paralyzed. Now, thanks to a team of scientists from the University of Pittsburgh, Copeland, maybe the commands of the brain to control robotic arms and even feels the pressure from touching anything. Such a wonderful sensation gave him a new modification attached artificial hands instead of the lost.
It"s a real achievement, this is a seriou...
Hi, thank you very much for the
work that you did for me, I
really liked the style of the
writer and all the facts were
presented in the concrete and
precise form, it was absolutely
not difficult to cope with huge
amount of information for
My friend told me about this
service, at the beginning I didn't
want to try it, but when the
paper was really urgent, I asked
for help here and I received my
paper just in time not to fail the
exam. Thank you, sorry, don't
know the name of the writer.
