Formation of amino acids by abiotic means in the oceanic lithosphere

By Allan Mai ‘20 Experimental studies and thermodynamic calculations have shown that abiotic synthesis of amino acids and hydrocarbons – specifically during the hydrothermal alteration of mantle rocks – is theoretically possible. However, this phenomenon has only recently been demonstrated in a terrestrial setting. Benedicte Menez and his team at the Institut de Physique du Globe de Paris used high resolution imaging techniques to obtain … Continue reading Formation of amino acids by abiotic means in the oceanic lithosphere

Determining the Sex of a Fingerprint

By Shannon Bohman ’19 An new innovative test may help determine whether a fingerprint comes from a man or a woman. Certain amino acids are twice as prevalent in women than in men, meaning that testing for amino acid concentration found in fingerprints can determine the gender of the person they belong to. For more than a century, fingerprints have been analyzed as if they … Continue reading Determining the Sex of a Fingerprint
