Physicist Andrew Dickerson, from the Georgia Institute of Technology in Atlanta (USA), has calculated the optimal speed at which dogs and other furry animals should shake themselves to remove water after a bath and remain completely dry.
The lunar soil contains frozen water, carbon monoxide, carbon dioxide, silver, mercury ... according to a NASA study published today in the journal Science and carried out from the remains studied by the LCROSS probe.
"Rivers in crisis" warns the cover of the latest issue of the journal Nature. The figures in the report you refer to are staggering: environmental stress, agricultural runoff, pollution and invasive species threaten the rivers that serve 80% of the world's population.
With the help of ESA's Herschel Space Telescope, an international team of astrophysicists has discovered the first carbon-rich red giant with water vapor in its atmosphere. It is called CW Leonis, it is located in the constellation of Leo, 500 light years from Earth, and with a radius of 500 suns it is the brightest extrasolar object in the sky in the infrared. Details are published today in the journal Nature.
The Dolphin Hydrofoil watercraft, designed by Nikko Van Stolk, meets all the requirements to become the watercraft of the future. Although at the moment it is only a concept, its creator has conceived two hydrofoils, an elliptical front and a rear one, which allow it to rise when moving, almost as if it were flying.
A team of scientists has presented a clinical trial during the National Meeting of the American Chemical Society (ACS for its acronym in English) that shows that drinking two cups of water before eating helps you lose weight and fight obesity.
In recent months, some studies have been published suggesting that the interior of the Moon contains more water than scientists previously thought, but now a new analysis of lunar samples collected during NASA's Apollo missions indicates that the Moon essentially it does not have any water.
If we fill a glass with water to the brim and carefully place a needle on its surface, we will verify that, miraculously, it does not sink. The truth is that it is not a miracle but a diaphanous example of what in physics is known as surface tension, which makes the water form drops and does not spread. And it is that the water is wet, but not much.
