The discovery of Earth's youngest-ever banded iron formation is changing how scientists understand the evolution of complex life, according to a study by University of Alberta geologists.
Every living organism expresses fine cellular protrusions known as cilia. Flagellates need them to move, roundworms to find food, and sperm to move towards the egg. Cilia form fine protective hairs in the lungs and play a ...
Cell division is one of the most fundamental processes of biology. It's what allows all living things to grow, multiply and form complex structures. But scientists still don't understand many of the details behind the process.
A team of researchers affiliated with several institutions across the U.K. has developed a framework for using virtual reality (VR) systems to teach chemistry. In their paper published on the open access site Science Advances, ...
Toxoplasmosis is a widespread infection caused by the parasite Toxoplasma gondii, which multiplies within a host and irreversible tissue damage. Humans primarily become infected by eating undercooked meat and poorly washed ...
Data from the international Cassini spacecraft have revealed complex organic molecules originating from Saturn's icy moon Enceladus, strengthening the idea that this ocean-world hosts conditions suitable for life.
Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus. Southwest Research Institute scientists ...
In recent decades, researchers have been able to produce structures from single atoms. One of the first examples was presented by D. M. Eigler and E. K. Schweizer in 1990 in Nature, a tiny IBM logo formed from just a few ...
Some of the earliest complex organisms on Earth—possibly some of the earliest animals to exist—got big not to compete for food, but to spread their offspring as far as possible.
In the past two decades, NASA spacecraft have identified potentially habitable environments throughout the solar system and beyond. Spacecraft on Mars have found evidence that lakes and streams once covered the planet, protected ...
