Mixed fungal cultures: a more potent method of crude oil biodegradation

2022, Biology, Engineering • February 27, 2022

A diagram showing how a fungal cell combines with the hydrocarbon compounds in oil (Image Source: Li et al., CC BY 4.0) Oil spillage has always been a major challenge to environmental health, especially in top oil producing countries like China, Saudi Arabia, and India. For instance, it has been shown that a 2010 oil …

Genomic Research For All Humanity

2022, Biology, Medicine • January 26, 2022

From DNA to Life. (Source: Wikimedia Commons, William Crochot) Our DNA is like a secret code – 6 billion base pairs (per cell) but only 4 letters, repeated over and over in a seemingly random order. The structure appears relatively simple, but those nitrogenous bases of DNA store the secrets of life, death, evolution, and …

The Looming Pandemic of Antimicrobial Resistance

2022, Biology, Medicine • January 24, 2022

Extensive and irresponsible use of antimicrobial drugs is one of the leading causes of antimicrobial resistance. (Source: Wikimedia Commons, freestocks.org) Most of us never thought that our lives would intersect with a pandemic. Yet, COVID-19 may not be the only pandemic witnessed in the 21st century. Antimicrobial resistance (AMR) is standing in the wings, ready …

Oncogenic Competence in Melanoma: Assessing the Cancerous Potential of Different Cell Lineages to Identify New Anti-Tumor Targets

2021, Biology, Medicine • November 28, 2021

Cover Image: Melanoma in a skin biopsy with H&E stain.. (Source: Wikimedia Commons, KGH) Melanomas, like most cancers, result from genetic mutations that effect cell cycle proteins, causing uncontrollable cell replication. These mutations can occur as a cell is replicating and differentiating from pluripotent cell lineages into more specialized forms. In melanomas, the onset of a …

Acoustic Reporter Genes: The Newest Breakthrough in Cell Visualization

2021, Biology • September 24, 2021

Figure: A fluorescent protein is expressed in human epithelial cells of the Henrietta Lacks (HeLa) strain. Scientists have long used reporter genes coding for fluorescent proteins to visualize the expression of genes of interest. Now, the development of acoustic reporter genes allows the same sort of local visualization to be achieved by sound. (Source: Wikimedia …
