If I should think of all things in the world,A tiny neuron in my brain is you.Your axon weaves throughout my cortex, twirled—About my thalamus your dendrites grew.When not around, chloride ions invadeAnd inhibit my action potential,Obstructing second-messenger cascadeAnd making sodium less substantial.Occipital lobe neural synapsesFire when you enter my field of view—My nervous system instead collapsesAs neurites shrug and declare, “I am through.”For when you're here my whole body goes […]
As SCOTUS debates the constitutionality of Proposition 8 and DOMA this week, Facebook users all over the nation have become part of a burgeoning social media trend. Supporters of marriage equality have been changing their profile pictures to the icon on the left, a version of the Human Rights Campaign logo designed specifically to indicate [...]
Over at Copasetic Flow, I wondered briefly last week whether electrical engineering notation and quantum mechanics notation had shared a common background and if so, which was the progenitor. A few days ago I came across a helpful article by … Continue reading →
There is nothing either good or bad, but thinking makes it so. - William Shakespeare, Hamlet According to a poll from the Pew Research Center that has come out just in time for this week’s historic decisions on marriage equality, we should all be concerned. As it turns out, there’s a tremendous amount of bias [...]

Large groups of humans emulate natural phenomena in surprising ways,
especially when faced with extreme conditions such as riots, rock
concerts, or earthquakes.
They may behave like molecules in a gas or in solid material, schools
of fish, or flocks of birds, all without thinking or direction,
researchers have […]
The big news today is that our Universe is a little older than we thought, has a little more matter in it, and is every bit as strange as we’ve come to expect. Some numbers got shifted around a bit, but things are pretty much what we cosmology-watchers expected. It’s not a bad thing, in [...]
Identifying a genetic basis for human intelligence is fraught with huge ethical, social, and political implications. If we knew of gene variants that increased intelligence, would we try to engineer them into our children? Or use them to determine who gets college loans? Or maybe just discourage people carrying the wrong variant from having children? So you'd think that researchers working on that topic would proceed with extra caution, and make sure their conclusions were absolutely

If you ever find yourself working in an infectious disease laboratory, whether it’s of the diagnostic or research variety, the overarching goal is not to put any microbes in your eye, an open wound or your mouth. Easy enough, right? Wear gloves, maybe goggles, work in fume hoods and don’t mouth pipette. When working with [...]
