atively coarse resolution of diffusion MRI to the subcellular level of electron microscopy. That’s a story for another day, but if you’re interested in this topic, I highly recommend Sebastian Seung’s eminently readable 2012 book, Connectome: How the Brain’s Wiring Makes Us Who We Are. Back to the Allen Institute datasets. When you click on ‘Mouse Connectivity’, the site presents you with an index of injection sites, 47 in all….

Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids
…molecules themselves break down into a surprisingly small number of building blocks. The proteins that make up all of the living things on this planet and ensure their appropriate structure and smooth function consist of only 20 different kinds of building blocks. Nucleic acids, specifically DNA, are even more basic: only four different kinds of molecules provide the materials to build the countless different genetic codes that translate into all…

…almost twice as likely to say that they don’t want to live or work near a person with mental illness if they read an article about a person with mental illness involved in a mass shooting, according to a study published March 20 in the American Journal of Psychiatry.

Featured today are 10 more women who broke boundaries by their presence in physics. They lived from 1711 to 2000. While I again limited information to one paragraph, I tried to highlight how they got their start, what universities, family members, and scientists were supportive of them. For these women, without the support of fathers, mothers, husbands, and mentors (all male with one exception) their life in science would not have happened. Whil…
