So far it seems that the cases are being caused by viruses from the West African clade, which triggers milder disease than the other family of … Continue reading Monkeypox

Which Computational Universe Do We Live In?

"In 1995, Russell Impagliazzo of the University of California, San Diego broke down the question of hardness into a set of sub-questions that computer scientists could tackle one piece at a time. To summarize the state of knowledge in this area, he described five possible worlds — fancifully named Algorithmica, Heuristica, Pessiland, Minicrypt and Cryptomania — with ascending levels … Continue reading Which Computational Universe Do We Live In?

Histotripsy: Solid Tumor Oblation With Ultrasound

"Early tests suggested that the sound waves successfully decimated up to 75 percent of liver tumor material in the rat bodies, which enabled the little critters' immune systems to jump into action and beat the leftover cancerous tissues out of existence, preventing reemergence......The new treatment is called "histotripsy," and it noninvasively directs ultrasound waves so that the … Continue reading Histotripsy: Solid Tumor Oblation With Ultrasound
