Snffing out origins of methane: instrument identifies methane's origins in mines, deep-sea vents...

Methane is a potent greenhouse gas, second only to carbon dioxide in its capacity to trap heat in Earth's atmosphere for a long time. The gas can originate from lakes and swamps, natural-gas pipeli...

Nine steps to survive 'most explosive era of infrastructure expansion in human history'

A team of scientists call attention to nine issues that must be considered if there is to be any hope of limiting the environmental impacts of the ongoing expansion of new roads, road improvements,...

Full-annual-cycle models track migratory bird populations throughout the year

Many birds spend only a few months of the year in their breeding range before leaving to spend the winter in another region or even on another continent, and models that only make use of data from ...

Advancing multiple approaches for characterizing permafrost microbes in a changing climate

To better characterize the microbial activities in the thawing permafrost, scientists have reported on the application of multiple molecular technologies: "omics."<img src="//feeds.feedburner.co...

NASA Ames reproduces the building blocks of life in laboratory

NASA scientists studying the origin of life have reproduced uracil, cytosine, and thymine, three key components of our hereditary material, in the laboratory. They discovered that an ice sample con...

Animal functional diversity started out poor, became richer over time

The finding refutes a hypothesis by the famed evolutionary biologist Stephen J. Gould that marine creatures underwent an 'early burst' of functional diversity during the dawn of animal life.<img...

New data provided by seabed sediments on the climate within the Mediterranean basin over the cour...

Scientists have found new data on the weather in the Mediterranean basin over the course of the past 20.000 years thanks to the chemical composition of sediments deposited in its seabed.<img src...

A new level of earthquake understanding: Surprise findings from San Andreas Fault rock sample

Researchers studied quartz from the San Andreas Fault at the microscopic scale, the scale at which earthquake-triggering stresses originate. The results could one day lead to a better understanding...

Mystery solved: Why seashells' mineral forms differently in seawater

For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, someti...

Water in smog may reveal pollution sources

The chemical signature of water vapor emitted by combustion sources such as vehicles and furnaces has been found in the smoggy winter inversions that often choke Salt Lake City. The discovery may g...
