Sewage Can Soon Be Converted into Bio-based Fuel

Sewage Can Soon Be Converted into Bio-based Fuel

Recent research findings at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) has shown that wastewater treatment plants may have the potential to produce biocrude oil, which is a petroleum-substitute synthetic fuel, from ordinary sewage (1). The technological process being considered is called hydrothermal liquefaction (HTL) (2). In HTL, […]

Potential for Evaporation Energy to Become Main U.S. Power Source Ryan Kilgallon ’21   According to research conducted at Columbia University, renewable evaporation energy has the potential to create 325 gigawatts of power, nearly 70 percent of the country’s current power production, using lakes and reservoirs throughout the United States. […]

Astronomers Identify Rare Comet-like Binary Asteroid

Astronomers Identify Rare Comet-like Binary Asteroid Aadil Islam ‘21 Spotting a shooting star in the sky is an infrequent spectacle in itself, yet a German-led group of astronomers appears to have doubled their fortune this past year. In September of 2016, NASA’s Hubble Space Telescope was used to spot 288P, […]

Cassiopea jellyfish prove that sleep requires no brain By Armando Ortiz ’19 The mechanisms of sleep and its effects on the nervous system continue to baffle scientists with many unanswered questions surrounding this topic. One recent study on primitive jellyfish further adds to scientists’ questions about the origin of sleep […]

A Genetic Explanation for the Process of Aging

Genes direct the process of autophagy, a cellular degradation mechanism that is essential for destroying dysfunctional proteins, but can go awry as an organism ages.

Ancient DNA Explains Human Origins and Prehistory By Bradley Fox, ‘21 Genetic information from fifteen different Ancient African individuals living between 1,000 and 8,000 years ago has given modern researchers key information on the migration patterns of ancient humans (1, 2). A recent study, released in the journal Cell on […]
