This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Tetramates are bioactive natural products that feature a pyrrolidine-2,4-dione ring. Approximately 14% of sequenced strains of Streptococcus mutans, a causative agent of human dental caries, bear the muc biosynthetic gene cluster (BGC) to produce mutanocyclin (MUC). MUC is a tetramate that inhibits leukocyte activity, which protects S. mutans from the host’s immune attacks. Some S. mutans strains can also accumulate the intermediates of MUC biosynthesis called reutericyclins (RTCs), which have antibacterial activity. A recent study revealed that the feature ring in MUC is closed via lactam bond formation. This contrasts with most other tetramates, which form their rings via Dieckmann cyclization. It was found that RTC is converted to MUC via the deacylase MucF. Distribution analysis revealed that BCGs like muc are widespread in human-associated bacteria..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

WWII  POW Escape Tools: Monopoly and concealment tools
Unrestricted Use
0.0 stars

During WWII Monopoly game boards, along with other types of games were used to hide small undetectable items such as a tiny compass, files, and silk maps. POW's used the items to escape. When America entered the war, they used the British model to incorporate hidden escape tools into board games through the US Army's Escape and Evasion section, run by the expertise of a Civil Engineer turned Intelligence Officer, Captain, Robley Winfrey.

One way to introduce these documents would be:

1) To ask students to come up with a list of items that might be needed to escape from a POW camp.

2) After a list is generated, I would set out several board
games and ask students to design a way to hide the items within the game.

3) Then, after sharing their plans, I would use the
documents to reveal the actual way items were concealed
This could be done through a variety of formats: student research, power point, short film clip, etc.

Follow up discussion: technology and ingenuity used to develop for these tools
