Mars attracts: How Earth"s interactions with the red planet drive deep-sea circulation
Scientists from the Universities of Sydney and Sorbonne University have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulati.....»»
Rising desertification shows we can"t keep farming with fossil fuels
Three-quarters of Earth's land has become drier since 1990. Droughts come and go—more often and more extreme with the incessant rise of greenhouse gas emissions over the last three decades—but burning fossil fuels is transforming our blue planet......»»
Enzymes evolved mix-and-match characteristics to shape nitrogen metabolism diversity across the planet
To boost crops more efficiently in the future, the evolutionary past may hold key insights. The way that plants process nutrients has a rich back story—they rely on enzymes that have been evolving for billions of years. However, these enzymes are o.....»»
Could the ESA"s PLATO mission find Earth 2.0?
Currently, 5,788 exoplanets have been confirmed in 4,326 star systems, while thousands more candidates await confirmation. So far, the vast majority of these planets have been gas giants (3,826) or Super-Earths (1,735), while only 210 have been "Eart.....»»
Early Earth"s oceans of magma may have accelerated the moon"s departure
The Earth and moon have been locked in a gravitational dance for billions of years. Each day, as the Earth turns, the moon tugs upon the oceans of the world, causing the rise and fall of tides. As a result, the Earth's day gets a little bit longer, a.....»»

Image analysis highlights Aldabra Atoll"s remarkable shoreline resilience over 51 years
Despite sea level rise in the Western Indian Ocean, more than 60% of Aldabra Atoll's shoreline remained unchanged from 1960 to 2011, based on aerial and satellite image analysis. On average, the shoreline changed at a rate of 0.25 ± 0.36 meters per.....»»
How sulfur affects the carbon cycle of subtropical seagrass meadows: New findings from Florida Bay
Seagrass meadows have an important climate protection function due to their long-term carbon storage potential. An international research team led by the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) has now been able to show that seagr.....»»
Human settlement of Mars isn"t as far off as you might think
Could humans expand out beyond their homeworld and establish settlements on the planet Mars? The idea of settling the red planet has been around for decades. However, it has been seen by skeptics as a delusion at best and mere bluster at worst......»»
NASA"s Lucy spacecraft prepares for second Earth gravity assist
On Dec. 12, at 11:15 p.m. EST, NASA's Lucy spacecraft, currently in a two-year orbit around the sun, will skim Earth's atmosphere, passing only about 220 miles (360 kilometers) above the surface. This close flyby will result in a "gravity assist," pu.....»»
