Bacteria with Nanowires can Electrocute Metals Instead of Breathe Recycling Expensive and Toxic Metals with Bacteria

All life on Earth has to respire. For us this means inhaling oxygen to fuel our metabolism and exhaling waste gases like carbon dioxide. When we do this, we move the energy  from the food we eat to the oxygen READ MORE

Believe it or not, we can (kind of) measure the air pressure of early Earth! 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.

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.

Chasing Alien Worlds with a Flying Telescope SOFIA is the name of a telescope that flies in the stratosphere to collect data that is unimpeded by the Earth's atmosphere

The airborne Stratospheric Observatory for Infrared Astronomy (SOFIA) is a flying observatory aboard a modified Boeing 747 that takes infrared astronomy readings at approximately 41,000 feet above the Earth’s surface. It recently observed a mini-eclipse of the extrasolar planet named READ MORE

Why is the Sun Yellow? Red dwarf stars are much more common, so are we a fluke?

Jacob Haqq-Misra, Ravi Kopparapu, and Eric Wolf attempt to address this question in a recent paper titled “Why do we find ourselves around a yellow star instead of a red star?” and published in International Journal of Astrobiology.

Betting on Aliens Would you invest in the search for extraterrestrials for a chance to win big?

If intelligent aliens exist somewhere in the depths of space, then should we see signs of their technology? This question has motivated scientists involved in the search for extraterrestrial intelligence (SETI) to hunt for evidence of tell-tale signs of alien READ MORE

New Method for Detecting Signs of Life In the Universe A classic “biosignature,” or sign of life, is the presence of three gasses in a planet’s atmosphere -- oxygen, ozone, and methane.

by Marc Claire Research Scientist Detecting life on a planet beyond Earth would be one of the coolest things ever! In our paper, we talk about detecting signs of life on other planets that breathe out oxygen. While this strategy READ MORE

Expedition to find rare pipefish in Queensland Australia

My research interests are centered on the evolutionary relationships among species of seahorse and pipefish in the family Syngnathidae through morphological study and DNA sequencing. This entails collecting and observing fish for study via scuba diving and photography in shallow inshore water in READ MORE
