Memory for stimulus sequences distinguishes humans from other animals — ScienceDaily

Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities. Despite these differences, however, it has been difficult to identify specific mental capacities that distinguish humans from other animals. Researchers at the City University of New York (CUNY) and Stockholm University have […]

Volcanic eruptions triggered dawn of the dinosaurs — ScienceDaily

Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new Oxford University research has found. The Triassic extinction took place approximately 200 million years ago, and was proceeded by the dinosaur era. […]

On the road to creating an electrodeless spacecraft propulsion engine — ScienceDaily

Researchers from Tohoku University have been trying to find out how the plasma flow is influenced by its environment via laboratory experiments. And in doing so, have made headway on research towards creating an electrodeless plasma thruster used to propel spacecraft. The universe is made up of plasma — a gas so hot that its […]

Chemists develop hydrogel strings using compound found in sea creatures — ScienceDaily

Rice University chemists can thank the mussel for putting the muscle into their new macroscale scaffold fibers. The Rice lab of chemist Jeffrey Hartgerink had already figured out how to make biocompatible nanofibers out of synthetic peptides. In new work, the lab is using an amino acid found in the sticky feet of mussels to […]
