Genetic diversity is essential to the survival of a species. It’s easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two distinct versions of the species’ genome. Genetic diversity is essential to the survival of a species….

Foreign direct investments (FDI) in tropical countries in extractive industries like mining, logging and fossil fuels have a long, environmentally destructive track record in tropical countries. Are FDI in food systems another extractive industry?

A new study has unveiled surprising findings about mercury pollution: where it comes from and how it moves through the environment vary significantly depending on the ecosystem. In drier regions, most mercury is deposited through rain and snow. In wetter, forested areas, gaseous mercury from the air sticks to leaves, which then fall and carry…
When natural gas leaks from a subsurface pipeline, a ground cover of water/snow saturation, asphalt paving or a combination of these can cause the gas to migrate away from the leak site up to three to four times farther than through dry soil, a new study has found. When natural gas leaks from a subsurface pipeline,…
In the wake of the 2020 COVID-19 lockdowns, researchers in northern Italy noticed that notwithstanding the partial suspension of travel and industrial production in the region, the level of particulate matter in the atmosphere remained high.

You might think eating more sustainably requires drastic changes, such as shifting to a vegan diet. While a plant-based diet is undeniably good for the Earth, our new research shows modest changes to your eating habits can also have significant environmental benefits. You might think eating more sustainably requires drastic changes, such as shifting to a…
Crust and lithospheric mantle—the thinnest and thickest layers of the Earth’s lithosphere—and a wide range of dynamic processes that deform them can be studied by using high precision geodetic data taken directly from Global Navigation Satellite Systems (GNSS). GNSS data and data products can measure and help the user understand such factors as the Earth’s…
Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of thousands of different types of stars. Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers…
