"Dewdrop" by M.C. Escher, mezzotint, ca. 1948. Raindrop on a leaf reflecting intricate details of a window.
Just discovered the M.C. Escher museum offers guided tours for blind & visually impaired visitors (sells out quickly!). What a lovely opportunity to experience his tessellations and mind-bending buildings.

What Are the Best Schools to Study Marine Biology?
In this edition of βAsk a Marine Biologist,β Dr. David Shiffman gives aspiring marine scientists things to consider when looking for in a college or university.
ICYMI: My longest article ever for Scuba Diving Magazine answers one of the most frequent career advice quesions I receive... and the answer probably isn't what you think!

Columnar basalt outcrop in Shenandoah National Park (large lab the size of a small lab for scale). Viewpoint from below the outcrop. Columns were much larger than expected (column cross-section diameter ~50cm). Basalt is weathered with a greenish-tan weathering rind. πOutcrop: Compton Gap, Virginia (Mile 10).

Plastic is everywhere.
On todayβs dive, the E/V Nautilus/ ROV Hercules encountered a crushed plastic bottle on the abyssal plain- in the remote Pacific (Cook Islands @ 5,198 meters).
