New research based on the findings, published in several papers Wednesday in Nature and its sister journals, represents a “leap in understanding of the human body,” according to the Human Cell Atlas consortium. Regev compared scientific knowledge of cell biology before the Human Cell Atlas initiative with a “15th century map.”“Now, years later, the resolution of the map is a lot higher,” she said. The cell atlas aims to fill in a missing link between genes, diseases and treatment therapies. During the Covid-19 pandemic, the Human Cell Atlas community used the available data to reveal that the nose, eyes and mouth were most vulnerable to infection. “It was only clear through the Human Cell Atlas data that those cells were … entry points before the virus continued into the internal organs.

CNN —In a historic first, scientists have used gene editing to induce virgin birth in fruit flies, a major step in unlocking the mysteries of the intriguing phenomenon known as parthenogenesis. The researchers used fruit flies because they’re considered “model organisms,” meaning the flies are among a list of organisms that scientists have long studied in depth to gain a better fundamental understanding of biology. Fruit flies’ short life spans of about 80 days have made it easy to observe changes throughout generations relatively quickly. And prior research into fruit flies is so extensive it’s possible to order genetic mutations for some flies online. “There’s just so many tools,” Sperling said, “and the tools are easily, cheaply available to all researchers” when it comes to fruit flies.

CNN —If you have type 2 diabetes, drinking more coffee, tea or plain water may lower your risk of dying prematurely from any cause by about 25%, a new study found. However, drinking more sugar-sweetened beverages raised the risk of heart disease by 25% and the risk of dying from a heart attack or another cardiovascular event by 29%, the study said. Adults with type 2 diabetes who drink more coffee or tea lower their risk of heart disease, a new study said. There was a 26% lower risk of early death associated with drinking coffee, 21% for tea, 23% for plain water and 12% for low-fat milk. When both sugar-sweetened and artificial no-calorie drinks were replaced with coffee, tea, plain water and low-fat milk, there was an even lower risk of heart disease and death from any cause.
