Supernova Flashes and Silver Linings

New research from the Weizmann Institute of Science reveals that “cells in our brain form little hexagonal grids that keep us oriented, map-like, in our surroundings.” Weizmann’s resident blogger describes this finding as “a pyrotechnic flash of insight that changes how we understand the brain to work.” Game developers delight; this discovery shows “that you can really apply mathematical models to understand how our mammalian brains get their bearings.” It may also have immediate implications for understanding human brain disorders such as vertigo. Meanwhile, on ERV, Abbie Smith explores a silver lining emerging from ongoing research into the viral scourge known as HIV. Abbie explains that HIV viruses genetically reprogrammed by scientists to “modify relapsed acute lymphoblastic leukemia (ALL) patients T-cells” are prolonging and possibly saving the lives of kids. Continued genetic modification could transform HIV into a powerful tool for fighting cancer and other diseases. Finally, on The Pump Handle, Elizabeth Grossman writes that rapid job growth in oil and gas industry is shining a light on some of the most dangerous jobs on the planet. Elizabeth writes, “Last year, 112 oil and gas industry workers were killed on the job and about 9,000 suffered non-fatal, work-related injuries and illnesses.” Hazards include toxic chemicals, respirable silica, and radiation exposure, not to mention “motor vehicle crashes, fires, electrocution and explosions.” But a new alliance between OSHA, NIOSH, and the National STEPS Network promises to fight for better workplace safety for these very important employees. Oh and for those not satisfied with a metaphor: some real supernova goodness from Ethan Siegel.
