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, […]

  Nerve Stimulation Restores Consciousness in Previously Vegetative Individual By Bradley Fox, ‘21   More than 15 years ago, a 35-year-old man was involved in a near-fatal car accident that left him in a vegetative state. Since then, the man has been without improvement, persistently bound in a crippling state […]

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 […]
