Primordial gravitational waves, The Inflation and The Big Bang
The detection of gravitational waves by a team of scientists involved in the BICEP 2 collaboration is a prodigious discovery similar in importance and scale
to the discovery of Higgs field and it has consequences for cosmology and our perception of the
universe. The discovery has confirmed the last untested prediction of
Einstein's Relativity.
The BICEP 2 collaboration, the theoretical physicist Alan Guth, who proposed the Inflationary cosmology in 1980, the Russian American physicist Andrei Linde, who is the father of the Theory of Inflation and Eternal Inflation, may be crowned with Nobel Prize.
The Inflation offers an explanation for some very important problems in cosmology. Inflation makes one prediction, the existence of a primordial gravitational wave background with particular properties. Such gravitational waves would leave a characteristic signature in the CMB maps, namely a slight circular polarization waves.
For detecting the circular polarization wave or the called the B mode signal, BICEP 2 was able to measure features that are 1/100000000 of the CMB signal, which is itself 1/100000000 of the ambient thermal radiation. The BICEP 2 has got to be one of the most precise measurements in the history of science.
The existence of the CMB was a prediction of the Big Bang Theory and its detection provided the best evidence for the Big Bang, the BICEP 2 is the evidence that convinces us that Inflation really happened.

BIOMOD: Design and construction of possible biomolecular gravity sensor
Currently different theories describe the presence of gravitational fields which has apparently been crucial during the biological evolution and development of the living beings when they emerged from the sea towards the continental land. Our work describes the design and development of a set of possible biomolecular sensors which could detect changes in the gravitational forces. These molecules are expressed by specific genes in Drosophila melanogaster flies and have homologous in the most animal species including humans. This group of genes was detected by microarrays techniques comparing RNA sequences extracted from the pupae stage under real or simulated microgravity. Additionally, the development of a correlation algorithm such as a function between the MAS 5.0 and Affymetrix RMA allowed demonstrating that these group of genes meet with all the mathematical and physical conditions of a sensor. Future applications of these sensors in biotechnology, astrobiology, and medicine are highly encouraging.
