WOODS HOLE, Mass. Understanding how the brain works is a paramount goal of medical science. But with its billions of tightly packed, intermingled neurons, the human brain is dauntingly difficult to visualize and map, which can provide the route to therapies for long-intractable disorders. In a major advance published next week in Nature, scientists for the first time report the structure of a fundamental type of tissue organization in brains, called neuropil, as well as the developmental pathways that lead to neuropil assembly in the roundworm

Researchers looking for mRNA were ridiculed by colleagues Luckily, that didn t stop them

Researchers looking for mRNA were ridiculed by colleagues. Luckily, that didn’t stop them. Sixty years ago, the scientists who were pioneering the technology that would make today s COVID-19 vaccines possible were mocked and dismissed February 18, 2021 In this illustration, a ribosome (centre) is producing a protein (red) from an mRNA template (multicoloured); the COVID-19 vaccine uses mRNA to teach our bodies to recognize and attack the virus’s protein (Juan Gaertner/Science Photo Library/Getty Images) A few days before Christmas, Matthew Meselson, a 90-year-old professor at Harvard, called his university’s health service to inquire about being vaccinated against COVID-19. He was eager for his shot. Meselson felt imprisoned in his Cambridge apartment, just blocks from the campus where he’d worked for six decades. He’d officially retired from teaching at the beginning of 2020, but continued his research as much as possible throughout the pandemic, wearing a K95 mask t
