The world being comprised of a multiple of nations has its advantages but also a lot disadvantages. One of the most important facts is that we do not use the same time measuring system, the same temperature system, not even the metric system. So, something had to be done so that someone from a foreign country knew ho... |

Regardless of the current season or your location on the globe, the weather affects you, one way or another. If you don't want weather conditions to take you by surprise, make sure you're always up-to-date with the local forecast. It may not always be completely accurate, but it does give you a general idea... |

There is a series of physical phenomena issues which prevents astronauts from having a hot drink in the cold solitude of outer space. Recently, this problem has been addressed by two Costa Rican students who have successfully built a coffee maker that would overcome the cruel restrictions of outer space.Perhaps the t... |

Experts have put much time into coming up with the ideal technical, physiologic and mathematic factors that are responsible for people taking their perfect shower. This will help the Mira Showers company produce the devices that would eventually create the ultimate showering experience. A group of scientists fro... |

The Galileo thermometer, or thermoscope, is a device named after the Italian physicist Galileo Galilei and designed to measure temperatures with a relatively good accuracy, although today it is mostly used as a decoration item. Unlike most classical thermometers, the Galileo thermoscope relies on the buoyancy princip... |

A thermometer is a device that can be used to measure the temperature of a certain object. Some of the most widely used and popular thermometers are the mercury and alcohol ones, although over the years several other types have been built, based on different physical changes that occur with the variation of temperatu... |

It is obvious that global warming is already impacting clime, water regime, plant and animal life. So far, a new analysis published in the journal Nature is the most exhaustive one, gathering data on the effects of global warming around the world, from cannibalistic polar bears to melting glaciers and earlier-bloomin... |

With the help of the Very Large Telescope, ESO astronomers have recently obtained an ultraviolet signature of carbon monoxide molecules inside a well hidden galaxy located 11 billion light years away from Earth. The VLT used its UVES spectrograph for a period of 8 hours to study the galaxy, during which time it obtai... |

The summer is coming and our thermo-regulation system will be once again pushed to the limits. Did you know that the human body is more resistant to cold than it is to heat? The fact is that we have physiological mechanisms more effective for combating the cold than the heat. Temperature is a parameter characterizing... |

Very little is known about how high-temperature gas in a condensed state - such as the one inside giants like Jupiter, Saturn or other gas giant exoplanets in the galaxy - behaves. In order to get a better understanding of the evolution of gases in these exact thermodynamic conditions, a collaboration between the Lab... |

The summer of 2007 registered the record of ice melting in the Arctic. Now, satellite data obtained by NASA reveals that the Arctic ice has recovered weakly, despite a very cold winter, and this summer melting could be another hit.In some Arctic areas, the colder-than-average winter of 2007-2008 has caused an increas... |

Temperature can have an unlimited increase but it cannot drop below -273.15o C (0 absolute). Every minute, each square cm of the Earth's surface receives about 2 calories from the Sun. The human body too produces heat, following the burning of organic chemicals. In 1620, Francis Bacon stated that movement is the... |

There are 112 active or inactive volcanoes in Costa Rica, but Poas, 2,700 m (9,000 ft) tall, is extremely unusual. It is not the most active (this being Arenal, 1,500 m/5,000 ft tall) nor the tallest (this being Irazu, 3,400 m/11,330 ft tall), but it has two craters: an active one, while the other holds a lake surrou... |

The Earth's mantle can stretch up to 2,900 kilometers below the surface, thus the only way to study it is to conduct measurements on the speed of seismic waves which travel through it, in order to determine the rough composition and density. However, a new research conducted relatively recently has shown that ag... |

You already know this: the sex chromosome from your father dictated your sex: boy for Y, girl for X. It's the same case with all the mammals. The mother will always come with an X chromosome. But in reptiles, there are neither sex chromosomes, nor sex portions on the chromosomes. All the eggs have the potential ... |

You may have heard about scorpions, cockroaches or mice resisting atomic explosions during nuclear tests. "As tough as a bacterium" can turn into a scientific saying.

The only warm-blooded ("homeotherm") animals are mammals and birds. The rest are denominated cold-blooded or poikilotherm. Indeed, poililotherm ("with variable temperature") is a proper denomination. Birds and mammals generate warmth on their own, by burning calories, to maintain a constant body temperature. The poik... |
