infinity-imagined:

A helical TALE protein molecule wrapped around a double helix of DNA.  TALE stands for “Transcription Activator-Like Effectors”, they are produced by Xanthomonas bacteria when entering a plant cell.  They manipulate the host cell by switching on certain genes that make the plant cell more susceptible to infection.  TALE subunits bind to the nucleotides of DNA in a 1:1 ratio, and each subunit has a pair of amino acids that is specific to a single DNA base.  This enables the TALEs to recognize and activate specific sequences of DNA.

With and without UV light #minutephysics pumpkin

Derek and Henry are at my house and they made this insanely cool secretly UV-activated water molecule out of pumpkins. 

Of course they did. These guys!

cinnamic-aldehyde:

Nickel tetracarbonyl.  A highly toxic, but very useful organonickel compound.  Nickel tetracarbonyl is produced industrially during the purification of nickel metal.  It is synthesised by passing carbon monoxide gas over impure nickel at 130˚C to selectively remove pure nickel.  The gas is then heated up to 250˚C where it will decompose back into nickel metal and carbon monoxide.  As with most nickel salts, nickel tetracarbonyl is very toxic, with its LD50 being around 3ppm for a 30 minute exposure.

as a celebration of my recent return to the worlds of chemistry and academia, let’s share a moment of appreciating how interesting looking molecular orbitals are.  (in case you are vaguely curious as to what they are, each one is a depiction of where the electrons orbit around in a molecule.)
