OAKLAND, Calif. - More than 80 percent of all waste from Pennsylvania's oil and gas drilling operations stays inside the state, according to a new study that tracks the disposal locations of liquid and solid waste from these operations across 26 years. Numerous human health hazards have been associated with waste from oil and gas extraction, including potential exposure to compounds known to cause cancer.

The iconic "death roll" of alligators and crocodiles may be more common among species than previously believed, according to a new study published in Ethology, Ecology & Evolution and coauthored by a researcher at the University of Tennessee, Knoxville.

New research from the University of East Anglia reveals how soil bacteria build the only known enzyme for the destruction of the potent global warming and ozone-depleting gas nitrous oxide.

Alongside carbon dioxide (CO2) and methane, the greenhouse gas nitrous oxide (N2O), commonly known as 'laughing gas', is now a cause for great concern, and there is much international focus on reducing emissions.

Researchers from Drexel University and Trinity College in Ireland, have created ink for an inkjet printer from a highly conductive type of two-dimensional material called MXene. Recent findings, published in Nature Communications, suggest that the ink can be used to print flexible energy storage components, such as supercapacitors, in any size or shape.

Of all the different possible methods to combat anthropogenic climate change conceived of so far, among the least studied is climate engineering.

An umbrella term for large-scale projects designed to disrupt the Earth's carbon cycle or radiation balance, climate engineering has only relatively recently been included in the conversation about methods that could mitigate the harm caused by carbon emissions.

Scientists from the University of East Anglia have discovered a unique oil eating bacteria in the deepest part of the Earth's oceans - the Mariana Trench.

Together with researchers from the China and Russia, they undertook the most comprehensive analysis of microbial populations in the trench.

The Mariana Trench is located in the Western Pacific Ocean and reaches a depth of approximately 11,000 metres. By comparison, Mount Everest is 8,848 metres high.

Well-adorned or well-endowed - but not both. Evolutionary biologists at the University of Zurich have for the first time demonstrated that male primates either have large testicles or showy ornaments. Developing both at the same time may simply take too much energy.

New Haven, Conn. - Cthulhu is calling from the ancient depths -- and this time, researchers are only too happy to speak its name.

Researchers at Yale, Oxford, the University of Leicester, Imperial College London, and University College London have identified a 430 million-year-old fossil as a new species related to living sea cucumbers. They named the creature Sollasina cthulhu, after H.P. Lovecraft's tentacled monster, Cthulhu.

A study announcing the discovery appears April 10 in the journal Proceedings of the Royal Society B.

CAMBRIDGE, MA -- The biggest source of global energy consumption is the industrial manufacturing of products such as plastics, iron, and steel. Not only does manufacturing these materials require huge amounts of energy, but many of the reactions also directly emit carbon dioxide as a byproduct.

The discovery provides a new characteristic 'biosignature' to track the remains of ancient life preserved in rocks which are significantly altered over billions of years and could help identify life elsewhere in the Solar System.
