  • Unicorns and Brainbows

    orite, shown below: A cerebellar flocculus, a lobe in the cerebellum, from the original Brainbow paper (Source) Since its original description, researchers have used the Brainbow concept extensively — it has been cited 361 times, according to the Web of Science – and extended it into zebrafish and fruit flies, both species that researchers frequently use in experiments to trace gene expression and how animals develop. But though Lich…

  • Tiptoe through the thalamus…

    ection of images, collected by injecting hundreds of mice, preparing thousands of brain slices, and represents gigabytes upon gigabytes of data, which Allen Institute researchers have then reconstructed into a kind of virtual 3D brain. In the parlance of neuroscientists, this dataset represents a first-pass attempt at a “connectome” – a brain-wide map of neural connections. But it’s definitely not the last; the connectome is vast beyond re…

  • Friday roundup: Nature is beautiful, weird, terrifying, & gross, and vaccines are a social responsibility

    d to head up the Pentagon’s 100-year Starship project . Nature is beautiful. Nature is weird. Nature is terrifying. National Geographic has collected together its best “Photo of the Day” selections from 2012, and this one has stayed with me since I saw it earlier this year. Astonishing.  Otters chase a butterfly . You may know that a group of crows is called a “murder.” But did you know that a group of otters…

  • Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids

    …ll selection of different materials: bricks, mortar, iron, glass, and wood. Arranged in different ways, these few materials can yield a huge variety of structures. We encountered functional groups and the SPHONC in Chapter 3. These components form the four categories of molecules of life. These Big Four biological molecules are carbohydrates, lipids, proteins, and nucleic acids. They can have many roles, from giving an organism structure to be…

    …s to capture, store, and interpret — about a terabyte’s worth per hour. Using those data, Keller and Ahrens tracked the activity of individual neurons (well, more or less — they actually tracked neuron-sized 3D pixels, called “supervoxels”) as they turned on and off, from which they could identify collections of neurons (supervoxels) that appeared to act in synchrony and might therefore be part of the same neuron cir…

  • After Newtown missteps, journalists get guidelines

    …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. Interestingly, this tendency is the same even if the article avoids any mention of mental illness. This may be because this link between violence and mental illness is deeply engrain…
