In class 2.737 (Mechatronics), the most powerful teaching tools include pen and paper: “Students have to be able to work out things on a piece of paper, and make sketches, and write down key calculations in order to be creative,” David Trumper says. https://lnkd.in/e8FAesqr

Nature Neuroscience publishes a special issue on glia! Our August issue just went live, and it's a special issue on glia. Glia is a blanket term that refers to several very different cell-types: astrocytes, microglia and oligodendrocytes (as well as their antecedents, oligodendrocyte precursor cells). Research into glia has become one of the most exciting and dynamic subfields of neuroscience, yet there is still much to be discovered about the diverse forms and functions of these cells. As the editors of Nature Neuroscience, we have been exhilarated by the pace of discoveries in this area and are delighted to showcase some of this transformative work in our pages. This month’s issue represents a celebration of glia from start to finish. We begin by highlighting some exciting papers about glia that have been published in other journals in recent weeks. We share conversations with established leaders and emerging voices in the field, Lucas Cheadle, Sonia Mayoral, Beth Stevens and Andrea Volterra. A Review from Lindsay Osso and Ethan Hughes challenges the dogmatic view of myelin as static and illuminates what is known about its renewal and remodeling. We also present primary research papers that reflect the breadth of the glial research field. Tewari et al. describe how astrocytic regulation of synapses depends on perineuronal nets, and O’Shea et al. characterize border-forming wound-repair astrocytes that emerge following spinal cord injury or stroke. Foerster et al. demonstrate a role for oligodendrocyte heterogeneity — specifically cells of dorsal versus ventral origin — in brain development, and we learn about roles for oligodendrocyte lineage cells in diseases that have mostly been thought of as involving neurons: neurofibromatosis type 1 and prion-induced neurodegeneration. Three papers examine interactions between microglia and other glial cell types: Kedia, Ji and colleagues reveal how CD8+ T cells trigger microglia to damage myelin in a mouse model of Alzheimer’s disease; Chen, Luan, Liu and colleagues describe how brain injury causes astrocytic ATP release (an ‘inflare’) that in turn signals to microglia; and Huang, Wang and colleagues examine how plexin-B1 expressed in periplaque reactive astrocytes in a mouse model of Alzheimer’s disease restricts access of microglia to amyloid plaques. Brown et al. even describe some circuit maturation processes that do not require microglia. And, rest assured, we have some compelling papers for our neuron-loving readers, too.

In the face of threats from other groups, humans, chimpanzees, and a selection of other species get closer to their own.

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan.
