Sleep Loss and College Student Performance

The college experience is of great value in providing emerging adults with a structured environment in which they can gain the knowledge, skills, and independence to chart their own path, become successfully employed, and contribute to society. However, this experience comes at great cost given rising tuition fees and ballooning student debt, and thus, it is vital that the college years be as efficacious as possible. A potential obstacle to maximizing success in college is the high prevalence of sleep loss and irregular sleep schedules among college students.

Microbial Farming for Future Agriculture

Intensification farming practice which mainly depends on agrochemical fertilizers and pesticides to meet the global food demand causes many problems to the environment. For instance, the high rate of synthetic nitrogen fertilizers utilization in the farmlands could damage the environment through some chemical and biological processes such as leaching, run-off, and volatilization.

Compare and Contrast Gene Regulation in Bacteria and Human

To understand how gene regulation is controlled in both prokaryotic (Bacteria) and eukaryotic (Human) cells, we have to understand how a gene codes a functional protein in a cell. The process occurs in slightly different manners. 

Prokaryotic organisms (i.e. Bacteria) are single-cell organisms which lack a nuclear membrane, and their DNA floats freely in the cell cytoplasm. The transcription and translation processes occur simultaneously in the cytoplasm. When the resulting protein is not required, the transcription process is stopped. As a result, the fundamental method to control what type of protein and how much protein is expressed in a prokaryotic cell is the regulation of DNA transcription. When more protein is needed, more transcription occurs. Therefore, in the prokaryotic cell, the control of gene regulation is mostly at the transcriptional level.
