Learn how the CRISPR prokaryote immune response systems were first discovered and the development of the CRISPR-Cas9 gene-editing tool.
We must preserve microorganisms for research continuity and to prevent frustrating delays. Here are several reliable ways to do it.
Digital images are essential to communicate your data. Get the information and tools you need to take your scientific illustration to the next level!
T4 DNA ligase is the swiss army knife of ligases, but it can’t always do it all. Find out what it’s good at and the alternatives available for the things it struggles with.
As the vast majority of bacteria cannot be readily cultured in the laboratory [1], culture-dependent methods to investigate bacteria grossly underestimate the diversity of bacterial communities. To investigate unculturable bacteria without isolating them, culture-independent methods such as sequencing have been used. Unculturable bacteria can be identified by PCR amplification and sequencing of housekeeping genes such…
What is the first image which comes to mind when you think about microalgae? Green scum that covers the surfaces of ponds? Unsightly stains on pavements and walls? Far from being a nuisance in ponds, lakes, drains and on surfaces, microalgae are fascinating microorganisms which are used to understand various biological processes. Microalgae have been…
Does your laboratory resemble the nest of an overly enthusiastic laboratory rat that went on a scavenger hunt and squirrelled away all that it has found? Do you find yourself playing Jenga with stacks of Petri dishes and freezer boxes? Have you ever attempted to decipher the meaning of the mysterious string of numbers on…
Estimates indicate that there may be up to 2 billion living species of organisms, each with conserved and unique biological mechanisms that are vital for survival. How do scientists understand them all? Enter model organisms. Model organisms, as the name implies, are living things which are used as representative models for understanding other organisms. They…
Biologists have a long tradition of drawing specimens as a form of data collection before the invention of the camera. The ability to present information in the form of illustrations is an important but often understated skill in a scientist’s toolkit. Scientific illustrations in publications run the gamut from schematics, 3D models, cartoons, and even…
Imagine that you want to test the efficiency of an antimicrobial treatment in inhibiting a certain bacterial pathogen. As part of the experiment, you expose the bacteria to the treatment and monitor the cultivability of the microorganism by counting the number of colony forming units (CFU) formed on culture media. If the microorganism is sensitive…
