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.

A crater on Mars may be a future landing site Rock formations on the Jezero Crater on Mars give us clues that there were probably active rivers there at some point.

Here on Earth, scientists study layers of sediment like dirt and sand to better understand how rocks form. The same contextual clues geologists use to explain how sedimentary rocks form on Earth can also be applied to extraterrestrial planets. Recent READ MORE

What happens if we send signals into space? Scientists explore potential risks of intentionally and unintentionally transmitting information into space

By Margareth Cheng-Campbell Blue Marble Space Institute of Science, Young Scientist Program For over a hundred years, humans on Earth have been using radio transmissions to communicate with each other. This ability to communicate around the globe has brought people READ MORE

How Bacteria Platoons Communicate to Conquer How bacteria called Pseudomonas communicate with each other during infection

The more we know about how pathogenic bacteria arrive to and colonize our bodies, the better we can take measures to help our immune system combat them. While most bacteria that we coexist with are beneficial to us or at READ MORE

Detecting Distant Planet Atmospheres From Afar Recent research on exoplanet GJ 1132 b that revolves around a M-dwarf star has discovered an atmosphere with traces of compounds existing on Earth

By Nandita Hari Guest Contributor Humans have always been fascinated with the vastness of the universe and its hidden truths. For ages we have tried to explore and study the sky. The earliest study of the sky involved using the READ MORE

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

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

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.

Managing Mars: Who Has a Right To It’s Resources? Two scientists propose a method of divvying up Martian resources based on the concept of “Cooperative Sovereignty”

By Spandan Dash BMSIS Young Scientist Program Humans have long been fascinated by the huge Cosmos above us. Perhaps this fascination has been best put to words by Carl Sagan in his influential book, Cosmos: “The Cosmos is all that READ MORE

Can You Teach an Old Gene New Tricks? Scientists put an ancient gene into modern bacteria, like pressing rewind and play on evolution.

By Grishma Gupte BMSIS Young Scientist Program Evolution explains how living things change over successive generations, giving rise to diversity. Across the evolutionary history of Earth, the formation, changes, and extinction of species have been observed. Even though evolution happens READ MORE
