The mosquito, one of the most annoying insects of the summer season, is capable of flying in the rain despite the fact that a single drop from the sky weighs 50 times more than this tiny insect. How is it possible? Researchers at the Georgia Institute of Technology (USA) have used high-speed footage to unravel the mystery. And they have discovered that it does this thanks to its strong exoskeleton and low mass.

Incredible as it may sound, in 1972 a physicist decided to use science to answer this question. In an article published anonymously in the specialized magazine 'Applied Optics' the result was presented explaining that the calculations had been based on two passages from the Bible.

From now on, bad students will be able to justify themselves by stating that they are bad at physics "because it is difficult", and furthermore this fact is scientifically proven. Although it is something that almost all mortals knew, an article published in the journal Physical Review Letters confirms that, at least for certain problems, physics is very complicated.

For the first time in history, scientists at the University of Southampton (UK) have used physics and mathematics to recreate the natural sounds of other worlds, from lightning on Venus, to the winds on Mars and the crunching of ice from the volcanoes of Titan, the moon of Saturn. In addition, they have modeled the effects of different atmospheres, pressures and temperatures on the human voice on Mars, Venus and Titan.

Any child who plays on the beach knows that the physical properties of dry and wet sand are quite different: it is impossible to...

The challenging conclusion that CERN physicists came to after a recent experiment that pointed out that neutrinos travel faster than light (and therefore Einstein's theory of relativity was wrong) could be due to a cable failure. fiber optic cable from a GPS receiver, which was not making contact with the main clock.

Mathematicians from the University of Manchester are working on the theory of invisibility cloaks to develop covers that protect buildings and structures from vibrations and natural disasters such as earthquakes. As announced by William Parnell and his colleagues in the journal 'Proceedings of the Royal Society A', camouflaging certain components of structures with pressure rubber would allow large seismic waves not to "see" the building and "pass by", so that this would not suffer any damage.

Scientists at the Nanoscale Physics Research Laboratory at the University of Birmingham, UK, have broken a record by creating the world's smallest Valentine's heart. It is made of atoms and measures 5 nanometers by 3.5 nanometers, too tiny to be visible by the human eye, or even to be observed with the help of a conventional light microscope.
