Scientists were able to get molecular information from 1.7 million years old teeth using a new method that could completely change how we study extinct organisms.

An analysis of samples taken from the Iceman’s stomach has revealed new details about what people were eating thousands of years ago!

In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass...

It’s time for molecular analysis! On this episode of Crash Course Organic Chemistry, we’re learning about mass spectrometry and infrared spectroscopy through the lens of a forensic investigation. Put on your lab coats, and let’s solve...

What is proteomics? It's the study of the interactions, function, composition, and structures of proteins and their cellular activities. Dr. Chandni Kumar is a molecular biologist who works with proteins to ascertain all kinds of things...

The Martian climate remains one of the solar system's biggest mysteries: although cold and dry today, myriad surface features on Mars carved by flowing water attest to a much warmer, wetter past. What caused this dramatic transition?...

MAVEN is the first spacecraft specifically designed to study the Mars upper atmosphere, in order to better understand the evolution of its climate. By measuring windspeed and direction near the top of the...

What do you do if you have a sample from another planet, and you want to find out if it contains a certain molecule...maybe even one that will reveal that the planet can sustain life? When scientists face a situation like this, they...

Sample Analysis at Mars (SAM) is a suite of instruments developed for use on the Mars Science Laboratory. By looking for evidence of water, carbon, and other important building blocks of life in the Mars soil and atmosphere, this...
