To Improve Conservation Efforts of Shark Species

Wendy Wu ’22  As a keystone species, sharks play a large role in maintaining a marine ecosystem. Unfortunately, climate change, habitat loss, and commercial fishing have led to sharp declines in shark populations around the world. To conserve and rebuild shark populations, many island nations have established marine protected areas (MPAs). The effectiveness of a MPA depends on whether it accommodates the species’ behavior and … Continue reading To Improve Conservation Efforts of Shark Species

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
