According to a paper published in the online journal arXiv, it would appear that dark matter interacts with the human body more often than scientists first calculated. The new results suggest that the elusive stuff interacts with atoms in our bodies around 100,000 times per year.
Dark matter is a quantity that was ... |

When various organisms and plants first began conducting photosynthesis, the process did not result in the production of oxygen (anoxygenic photosynthesis). However, in time, a switch occurred, which enabled the emergence of an oxygenic (oxygen-production) version of the process. A team of experts now analyzes how th... |

The conclusions of a new scientific study indicate that our planet's atmosphere oscillated between a hydrocarbon-free and a hydrocarbon-rich state some 2.5 billion years ago, before the Great Oxygenation Event occurred.
This phenomenon saw the release of vast amounts of oxygen in the atmosphere, and ultimately... |

A heart attack is known among cardiologists as both myocardial infarction (MI) or acute myocardial infarction (AMI). It occurs when insufficient blood flow to a portion of the heart muscle leads to the death of the starved cells.
In many cases, heart attacks occur as a result of a blockage obstructing the coronary ... |

Data collected back in 2007, near Murmansk, in northwestern Russia, indicate that the emergence of oxygen in Earth's atmosphere did not occur in a single bound, but rather in small steps characterized by numerous starts and stops.

About 2.3 billion years ago, vast amounts of molecular oxygen (O2) made their way into Earth's atmosphere, during an time known as the Great Oxygenation Event (GOE). New data suggest that the molecules existed before that time, trapped in oceanic “oxygen oases.” At this time, the gas makes up for mor... |
