nature Magazine – March 23, 2023 issue: One of the main hurdles to putting autonomous cars on the road is how to ensure the reliability of the artificial intelligence that replaces the human driver. Evaluating the safety of an AI driver to the level of a human in a naturalistic environment would require testing across hundreds of millions of miles — something that is clearly impractical.

From mice with two fathers to cures for debilitating diseases, the transformative power of genomic technology requires some big decisions on what we want to do with it

Fears are rising about bird flu’s potential to spark a human pandemic, as well as its destruction of wildlife and farmed birds. An 11-year-old girl tragically died in Cambodia last week after catching avian influenza. That followed reports earlier this year of the virus spreading from mammal to mammal through a mink farm, and causing mass mortality in Peruvian birds and sea lions. Since the beginning of 2022, more than 50 million poultry birds in the United States, and a similar number in Europe, have either died of the disease or been killed in efforts to stem its spread. Can bird flu be stopped, and if yes, how?
Ancient philosopher Anaximander’s discoveries about rain, wind and the cosmos may make him the true force behind modern science, argues physicist Carlo Rovelli in his newly republished first book
Your cells crackle with electric signals that guide embryonic development and heal wounds. If we can learn to tweak this “bioelectric code”, we might be able to prevent cancer and even grow new limbs
Moves by Google, Microsoft and Baidu to bring AI chatbots into their search engines may bring big advantages, but they could also damage many industries and change the very way we interact with the web
