First, a loop back to his LAST (2020) SFI Seminar on 3D structure of living systems from biofilms to rainforest canopies:

"People often think of societies as cooperative, but some societies are NOT very cooperative. I prefer to put the focus on them as groups."
"Societies are just one aspect of belonging. There are groups *within* societies & that's what psychologists mostly focus on."

A few words on how this spray is generated and why the #beetle is not harmed in the process:
Hydroquinone and hydrogen peroxide are secreted by specialized glands and stored in a tank. Other glands produce catalyst enzymes such as catalases and peroxidases. 1/7
Hydroquinone and hydrogen peroxide are secreted by specialized glands and stored in a tank. Other glands produce catalyst enzymes such as catalases and peroxidases. 1/7
When the contents of the two glands are mixed, oxygen forms and in turn reacts with hydroquinone to convert it to benzoquinone. Pressure due to the buildup of oxygen then causes the hot mixture of water and benzoquinone to be expelled. 2/7
The explosion chamber is made of a mixture of chitin, proteins and waxes, which protect the beetle’s soft interior from the chemical mix, the high temperatures and the pressure. To withstand the #explosive force, the blast consists of a series of micro-pulses. 3/7

The TTFNC was founded on July 10th 1891 in order to: “...give pleasure to its members by observation of animal, insect and plant life in Trinidad”.

In 1892, the first issue of our peer-reviewed journal was published as an outlet for our members to publish interesting and novel #NaturalHistory observations. It continues to this day as "Living World, the Journal of the TTFNC". ttfnc.org/livingworld/in… 2/n #130yearsofTTFNC
The first issue of our journal included J. E. Tanner's breakthrough discovery that #leafcutter #ants (locally known as #bachacs) cultivate fungus & feed it to their larvae, rather than eating the leaves directly as previously thought. 🐜🌿🍄3/n #130yearsofTTFNC

Scout-initiated group raiding in ants is an incredibly rich collective behavior that can now be studied in the lab. Exciting new @biorxivpreprint from our lab @RockefellerUniv with @VChandra_ & @asafffgal biorxiv.org/content/10.110…. (1/8)
Scout-initiated group raids are stereotyped in the sequence of events, but there is interesting variation in the length of some phases. Lots of cool collective decision making and navigation as well. @biorxiv_evobio @biorxiv_neursci @biorxiv_ecology. biorxiv.org/content/10.110… (2/8)
Turns out that group raiding is the evolutionary precursor of army ant mass raiding, one of the most spectacular collective phenomena out there. However, we actually know very little about how collective behavior evolves mechanistically in any animal group. (3/8)
