Flowing water on Mars: What that means for ‘The Martian’
Faced with a sudden and urgent need for food, Mark Watney did what any astronaut stranded on Mars would do: he filled his living quarters with Martian soil, fertilized it with his own waste, built a contraption to chemically create water, and grew some potatoes.

Gulf Stream ring water intrudes onto continental shelf like “Pinocchio’s Nose”
Ocean robots installed off the coast of Massachusetts have helped scientists understand a previously unknown process by which warm Gulf Stream water and colder waters of the continental shelf exchange. The process occurs when offshore waters, originating in the tropics, intrude onto the Mid-Atlantic Bight shelf and meet the waters originating in regions near the Arctic. This process can greatly affect shelf circulation, biogeochemistry and fisheries.

Titan’s “bucket brigade” brings liquid to moon’s north pole
Researchers think they have found a veritable bucket brigade that has been slowly but surely drenching the north pole of Saturn’s moon Titan – the only world in the solar system, other than Earth, to have lakes, seas and rainy weather.

Asteroids have “fractured and pulverized” the moon’s subsurface
Large asteroids that crash into the moon cause fractures to the lunar crust that extend up to 25 kilometers (16 miles) below the moon’s surface, finds a new study. These cracks could contain a record of asteroid impacts that bombarded the inner planets billions of years ago, possibly shedding new light on the formation of our solar system and the origin of life on Earth, according to researchers.

High water tables can be a boon to crop yields
High water tables can be a bane to crop yields, compelling many farmers to drain their fields so their crops don’t drown when it rains.
But a high water table may not always be a bad thing. A new study shows it is actually a boon for some fields and during certain times of the growing season, casting light on opportunities for improving yield efficiency to meet global food demands.

Terraced craters: Windows into Mars’ icy past
Scientists studied terraced craters on Mars and found an underground chunk of ice the size of California and Texas combined.

New study shows significant tsunami strength for parts of Southern California
Tsunamis generated by earthquake faults off the Santa Barbara coast could pose a greater danger to the cites of Ventura and Oxnard than previously thought.
