Leaf-cutter ants are arguably among the most amazing living things in the entire world. They are mostly renowned for their ability to grow fungus “gardens” and also for the fact that they can carry chunks of leaves that are several times their body size and weight. Now, scientists have found yet another r... |

Researchers proposed a long time ago that atmospheric pressure might be one of the key factors determining the habitability of Earth-like planets. Over geological timescales, of millions to billions of years, variations in this pressure may be what determines a planet's ability to foster primitive life. A new st... |

Nitrogen is one of the important chemical for life on Earth. It composes the majority of our atmosphere, and it is an inert gas, meaning that it does not interact with other chemicals in its stable form. But the amounts of nitrogen in the air are currently changing, with the main additional sources being the burning ... |

Scientists at the California Institute of Technology (Caltech) recently made a discovery that may open up the way of studying the planet's elusive nitrogen cycle. While the paths other chemicals, such as carbon, take are relatively well known, nitrogen is still a bit of a mystery in the way it takes to circle th... |

Quantum computers are currently one of the largest objectives for the electronics industry. They will be able to calculate immensely complicated codes faster and more accurately than the current technology can, as they will make use of the quantic principle of superposition. This principle dictates that a quantum bit... |

Astronomers have known for a long time that the Sun is currently at the middle of its life cycle, having already burnt for more than 4.6 billion years. As a yellow main sequence star, it is expected to live a full life of about 10 billion years, but naturally, during this time, it will evolve. Sadly for Earth, this i... |

Researchers dealing with drills in the Antarctic ice sheets have recently managed to identify the chemical traces of a supernova explosion that took place more than 1,000 years ago, by analyzing minute amounts of the particles that remained trapped in the ice. The samples that have been analyzed for the new research ... |

Pluto is one of the smallest planets in the solar system, and it's located very far away from the Sun, beyond the orbit of Neptune. It's one of the dwarf celestial bodies, having a diameter of only one fifth that of the Earth. But, unlike our planet, it's made almost entirely out of rock and ice, and f... |

A team of astronomers led by Stephen Tegler from the Northern Arizona University in Flagstaff were culling through pictures of the biggest dwarf planet beyond Neptune called Eris, when they came across a startling discovery. The small plutoid (as this type of planets is named) sported major changes in its surface com... |

A typical Self-Contained Underwater Breathing Apparatus, or scuba gear for short, usually consists of a tank containing compressed air and a mouthpiece used to regulate the flow of air from the tank into the lungs. But breathing air in this manner is extremely inefficient, especially while considering the application... |

Most nitrogen pollutants released by humans into the Earth's atmosphere end up in the ocean, where they act as fertilizers and increase the production of marine plant life. This in turn determines a high absorption of carbon dioxide into oceanic sinkhole, according to a study carried out by Robert Duce, Atmosphe... |

Atoms are formed of a positively charged nucleus - containing protons and neutrons - and an outer shell of electrons spinning around the nucleus. Now, we know that the nucleus is found in the center of the atom, but individual electrons spinning at high speeds around the nucleus are rather hard to localize, which is ... |

Dry ice is basically frozen carbon dioxide. It might not sound like much but dry ice bears some unique properties that make it ideal for certain cooling applications. First of all, as its name says, it's dry, meaning that unlike other ices, such as frozen water, it does not go through a liquid state when heated.... |

Toothed whales represent the diving champions of all air-breathing animals. Sperm whales dive at depths of over 1,200 m (3,600 ft) for more than an hour, while Cuvier's beaked whale (a type of toothed whale) holds the record for diving amongst any sea mammal - 1,900 m (6,330 ft), that translate into 190 atmosphe... |

Diamonds have fascinated humans ever since they were discovered, with their breathtaking beauty and unsurpassed hardness. Thus, modern technology is seeking for new ways of synthesizing such crystals in industrial facilities, in order to make them available for everybody. An allotrope form of carbon, the diamond is t... |

For decades now, the United States used nitrogen-based fertilizers, believing that it would benefit the soil by building organic carbon into it; but a group of scientists studying the soil has recently found that nitrogen actually fertilizers deplete the carbon reserves from it.Scientist from the University of Illino... |

What's the similarity between your gut and the bottom of the ocean? Well, they're both dark and oxygen-poor places. And full of bacteria. Now, a group of Japanese researchers has discovered that some of the nastiest germs thriving in the human intestine, triggering some severe diseases could have evolved f... |

Many acids result from the combination of a nonmetal oxide with water.Water can be found in nature, the oxides can be dumped by human activity, especially the burning of fossil fuels. This is how acid rains result: rains filled with acids. The main causes are the nitrogen and sulfur oxides, that give nitric and sulfu... |

This is the process that fuels life on Earth: plants simply mix carbon dioxide from the air, water and sunlight to turn them into biomass and oxygen. Chemists would also like to be able to use CO2 as a carbon source just like in the photosynthesis for synthesizing organic reactions, but this is not as simple as it mi... |
