But when I learned that some of them had spontaneously developed optic vesicles—that is, precursors to eyes—I realized that ...

Our body fat may turn out to be a secret weapon in our everlasting fight against cancer. A new study released this week ...

In my own brief foray into the laboratory as an undergrad, I poured agar into probably hundreds of petri dishes, a tedious ...

There have been hundreds of successful experiments in petri dish cell cultures, dozens in lab animals, and in late 2004, an RNAi therapy was tested in humans for the first time. Yet experts in the ...

A large petri dish containing multiple clear and orange beads that are initially separated is shaken. Both the clear and orange beads become uniformly distributed throughout the container. Place the ...

In it, an apparently normal-looking petri dish is treated so as to reveal a message when wetted with water vapor. The contrast between hydrophobic and hydrophilic surfaces, which is not visible to ...

Weady noted that as the experiment continued, new stress hubs emerged in their simulated Petri dish, leading to shorter cells–a sign of slowed growth. The particles formed concentric circles, ...

It is therefore important that any petri dish or agar used is sterilised before use, and that aseptic techniques are used to inoculate the plates. An inoculating loop can be used to transfer bacteria.
