Viruses are the most numerous biological entities on the planet. Now researchers have identified over 140,000 viral species living in the human gut, more than half of which have never been seen before.
According to a new study, Earth, Venus and Mars were created from small dust particles containing ice and carbon. The discovery opens up the possibility that the Milky Way may be filled with aquatic planets.
A new study suggests that the extinction of North America’s largest mammals was not driven by over-hunting by rapidly expanding human populations following their entrance into the Americas. Instead, the findings, based on a new statistical modelling approach, suggest that populations of large mammals fluctuated in response to climate change, with drastic decreases of temperatures around 13,000 years ago initiating the decline and extinction of these massive creatures.
Scientists have put forth a new theory that could explain the origin and journey of the comet that killed the Chicxulub impactor and others like it.
A new study provides evidence of a mechanism by which climate change could have played a direct role in the emergence of SARS-CoV-2, the virus that caused the COVID-19 pandemic.
Life is an experience that everyone has and thinks they can recognize. A quality we think is very important. Yet no one can define it.
