Using Gas Bubbles in Lava to Predict Ancient Air Pressure Scientists can estimate what the atmospheric pressure was on Earth 2.7 billion years ago, and the findings may help us understand how life formed

What was the weather like in New York last week? You can look it up on What was it like on March 7, 1953, in the pre-internet era? You might be able to find it at the library, in READ MORE

For a Cooler Climate, Just Add Ice Should scientists attempt to slow climate change by intentionally increasing the size of the Greenland Ice Sheet to reflect sunlight away from the planet?

Should we geoengineer larger ice caps to reflect radiation away from the Earth to cool the climate? Is this a good idea? This article briefly explores these questions, based on the work of Jacob Haqq-Misra of Blue Marble Space Institute of Science.

Lasers and Fool’s Gold Give a Glimpse Into Our Ocean’s Past The amount of pyrite in the sea floor gives us an idea of how much oxygen was in the ocean millions of years ago.

The amount of trace elements in ocean pyrite correspond to ocean oxygen concentrations at different points in geologic time.

New Cavity Discovered in the Great Pyramid of Egypt Cosmic rays from space allowed scientists to detect a mysterious 4000 year old cavity deep in the Great Pyramid

An international team of scientists recently detected a new cavity in the 4000 year old Great Pyramid of Egypt! The detection method, muon tomography, is non-intrusive and so the discovery still awaits confirmation using more traditional techniques that involve (minimally READ MORE

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
