Production of ethylene is one of the most important chemical processes used today, with about 300 million metric tons of the tiny chemical produced each year. Ethylene gas is used to create everyday items like shopping bags and plastic film packaging.

A team of archaeologists at the Institute of Archaeology, HUN-REN Research Center for the Humanities, in Hungary, working with a colleague from Stockholm University, has revisited a mystery: a Roman era lynx skeleton buried in a pit with four dog skeletons, all layered above it.

In a study published in Science Advances, scientists have used new lithium isotope (δ7Li) data to show that continental clay export promoted organic carbon burial and thus atmospheric oxygenation during the Cambrian period.

University researchers have shown that a transition to green wastewater-treatment approaches in the U.S. that leverages the potential of carbon-financing could save a staggering $15.6 billion and just under 30 million metric tons of CO2-equivalent emissions over 40 years.

Seven hundred million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today's standards, the animal had a front and a back, a top and a bottom. This was a groundbreaking adaptation at the time, and one which laid down the basic body plan which most complex animals, including humans, would eventually inherit.

New research from the Crowther Lab at ETH Zurich illustrates a critical barrier to natural regeneration of tropical forests. Their models—from ground-based data gathered in the Atlantic Forest of Brazil—show that when wild tropical birds move freely across forest landscapes, they can increase the carbon storage of regenerating tropical forests by up to 38%.

Paleontologists from Flinders University have described three unusual new species of giant fossil kangaroo from Australia and New Guinea, finding them more diverse in shape, range and hopping method than previously thought.
