Whales and dolphins can resist cancer and their DNA reveals why
Whales, dolphins and porpoises are much better at fighting cancer than we are, and a DNA analysis brings us closer to understanding why cetaceans can do this Source: https://www.newscientist.com/article/2268865-whales-and-dolphins-can-resist-cancer-and-their-dna-reveals-why/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
A new study reveals that quantum physics can cause mutations in our DNA
Quantum biology is an emerging field of science, established in the 1920s, which looks at whether the subatomic world of quantum mechanics plays a role in living cells. Quantum mechanics is an interdisciplinary field by nature, bringing together nuclear physicists, biochemists and molecular biologists. …

How Oracle Sells Repression in China
In its bid for TikTok, Oracle was supposed to prevent data from being passed to Chinese police. Instead, it’s been marketing its own software for their surveillance work. From a report: Police in China’s Liaoning province were sitting on mounds of data collected through invasive means: financial records, travel information, vehicle registrations, social media, and surveillance camera footage. To make sense…
