Blue-green algae’s response to different nitrogen pressures may tell us what fossils to look for and what those fossils tell us about ancient air pressure.
by Sumeet Kulkarni Guest Contributor, BMSIS Young Scientist Program What was the weather like in New York last week? You can look it up on weather.com. What was it like on March 7, 1953, in the pre-internet era? You might be READ MORE
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.
The amount of trace elements in ocean pyrite correspond to ocean oxygen concentrations at different points in geologic time.
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
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
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
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
In a last scientific hurrah, the Cassini spacecraft has detected that hydrogen is being ejected from the moon’s ice-covered ocean.
All life on Earth survives because of the sun. Plants use a process called photosynthesis to transfer energy from the Sun’s rays into the sugars that build their stems and leaves. Animals either eat the plants directly, or eat other READ MORE
