To-day at 1:18 pm (CT) we all received a Presidential Alert, a wireless check, text message on our cellphones. It could have been either a thrill or terrifying depending upon our political affiliation. As an political independent, I sought more information about it and found and excellent article Trump Is Not Texting You in The Atlantic, which explains in detail about this mandated Wireless Emergency Alerts system.

There is a brief note in The New York Times explaining Why Onions Make Us Cry? It turns out that when we cut onions it releases  a chemical called lachrymatory factor (LF) which irritates our eyes. LF is by product of two molecules located in cells: sulfenic acid precursor floating around and a protein called alliinase in cytoplasm, which are released when onions are crossed and produce irritating LF. This chemical is used by plants as defense mechanisms from microbes & animals. An undergraduate student Josie Silvaroli, an undergraduate at Case Western Reserve University in Ohio helped explained this puzzle in a paper published in ACS Chemical Biology in July 2017.
