Mesmerising microbes: bacteria as you’ve never seen it before – in pictures
“As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative.”
"She criticized my organizational skills and told me that she didn’t see a passion or spark for doing research in me."
Pleading to passion are cop outs for not paying your, or providing sufficient guidance. This was squarely on the PI to begin with, by not reading the room or asking for timely feedback on workload. The the response left a culture of fear (nor one of responsibility and disclosure). Poor management as ever.
“The first known calculation of the Earth’s circumference was made 2300 years ago by a man called Eratosthenes. I remember in school, how impressed I was by how accurately the Earth’s circumference was measured such long time ago. Today we’re going to take a closer look on how his calculation was made.”
“The Harvard team established the practical makings of the first quantum internet by entangling two quantum memory nodes separated by optical fiber link deployed over a roughly 22-mile loop through Cambridge, Somerville, Watertown, and Boston.”
You can tell #Kuhn is thinking of #Wittgenstein, PI here: "to imagine a language means to imagine a form of life." This is from "Scientific Knowledge as Historical Product," 1977, first essay in The Essential Tension and also in The Last Writings of Thomas S. Kuhn.
Environmental historian Vicki Szabo and her team of archaeologists, historians, folklorists and geneticists are trying to figure out medieval Icelanders' attitudes to blue whales. Did they revere them as their protectors? Did they hunt them for food? Was it both? @hakaimagazine's Andrew Chapman reports on the work of this multi-disciplinary team, and what their findings might tell us about historical and modern whale populations.
