Lost & Found: The ancient Aitape Skull may be from the oldest known tsunami victim New research suggests that a skull fragment discovered in 1929 came from a tsunami victim some 6,000 years ago.

Tsunami are among the most destructive natural events that happen on our planet. From the Japanese term meaning “harbor wave”, tsunami occur when large volumes of water are quickly moved about in the ocean, which can be driven by events READ MORE

Life May Be Even Older Than We Thought! Careful analyses of the composition of ancient rocks betrays the presence of life

How long has life been around on Earth? Is life an inevitable part of planet formation? The second question is tough to answer, but if life formed soon after the planet formed, then this has important ramifications for the abundance READ MORE

Caves Host Gooey Biofilms Built by Methane-Eating Bacteria Scientists try to understand the composition of snottites, which are collections of bacteria named for their resemblance to boogers.

Although bacteria are unicellular and may be freely swimming in water or crawling on sediments, in many environments they live in clumps called biofilms. Biofilms are groups of bacteria that grow on a surface and huddle together by sticky carbohydrates READ MORE

Is Organic Farming Really Better? It Depends. Organic farming and conventional farming each have their own strengths and weaknesses that depend on application.

Forests Recover Well When Humans Get Out of the Way Being too eager to help a forest recover may be a waste of precious money

It goes without saying that forests are important. As the lung of our planet, they strongly contribute to converting carbon dioxide that we exhale into oxygen for us to breath. Since the dawn of civilization, forests have been under threat. READ MORE

Bacteria-Powered Battery Helps Remove Lake Pollution Combining aquatic plants with a microbial fuel cell effectively reduces nitrogen pollution in water

Nitrogen pollution is a big problem in standing water such as lakes and ponds. The nitrogen comes from many sources, often agricultural fertilizers. Some of this nitrogen is in the water, but the rest of it is actually trapped in READ MORE

Grow High-Tunnel Lettuce Year Round on Fish Waste Flow-through aquaponics may help improve winter lettuce yields for farms using high tunnels, giving fish poop a whole new purpose.

A group of agricultural researchers at West Virginia University wanted to find out if it was possible to grow lettuce year round using high tunnel aquaponics instead of traditional greenhouse methods. Aquaponics is a term that combines “aquaculture,” the practice READ MORE

What Causes Ice Ages? A New Proposal. Ice ages in the Southern Hemisphere are influenced primarily by sea surface temperature and atmospheric carbon dioxide

A new international study casts doubt on the leading theory of what causes ice ages around the world — changes in the way the Earth orbits the sun. The researchers found that glacier movement in the Southern Hemisphere is influenced READ MORE

When Dolphins Learned to Swim Convergent evolution in land to sea transitions in marine predators across major mass extinctions

For more than 250 million years, four-limbed land animals known as tetrapods have repeatedly conquered the Earth’s oceans. These creatures–such as plesiosaurs, penguins and sea turtles–descended from separate groups of terrestrial vertebrates that convergently evolved to thrive in aquatic environments. READ MORE

Hydrofracturing in the Greenland Ice Sheet New meltwater is not likely to further lubricate the Greenland Ice Sheet waterslide

Surface meltwater regularly travels to the bottom of the Greenland Ice Sheet and lubricates the flow of the ice into the ocean, but new research indicates that future increasing volumes of this meltwater are unlikely to speed the flow of READ MORE
