Introducing the most versatile piece of laboratory equipment: the septum. It’s a septum! It’s a makeshift SureSeal! It’s a makeshift vial adapter! It’s a holder for reaction tubes!

Small changes add up to big results. You can activate the movement.

In this video, mixtures of inks (likely printer toners) and fluids move and swirl. Magnetic fields contort the ferrofluidic ink and make it dance, while less viscous fluids spread into their surroundings via finger-like protuberances. (Video credit and submission: Antoine Delach)

slanty sides or die trying

This is the heated debate amongst chemistry students: what’s the best way to draw 5-membered rings? 1) The ergonomic flat bottom with low error rates but clumpy bond angles. 2) The slick-slanty-sided pentagon with classy bond angles, but when it goes wrong it goes very wrong.

What’s your verdict?

That one time my roommate couldn't watch Shane's Asagao Academy stream so I live-texted it to her instead (part 2).

Graphene Safely Interacts With Neurons in the Brain

Researchers have shown that graphene can be used to make electrodes that can be implanted in the brain, which could potentially be used to restore sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as Parkinson’s disease.

The research is in ACS Nano. (full access paywall)

While you see many varieties of the common mold in your house and garden, the scientific word to describe them has a fascinating history.  Aspergillus is a genus of 300 or so common molds found in all types of climates around the world.  The Aspergillus mold was first catalogued in 1729 by the Italian priest and biologist Pier Antonio Micheli. These molds are in the fungus kingdom and while almost all are microscopic, colonies of the mold are easily recognizable and can grow quite large. Viewing the fungi under a microscope, Micheli was reminded of the shape of an aspergillum, which is the Latin word for a holy water sprinkler, itself from Latin spargere meaning to sprinkle, and named the fungus for the shape of the sprinkler.

You can see the similarity above, in the image of a silver aspergillium next to a microscopic view of aspergillus mold next to a colony of aspergillus mold growing on a damp terra cotta pot.
