1 . Artificial intelligence (AI) has amazing potential to change the world, and we’ve only just begun to scratch the surface. As AI matures and people move further away from distinct programming and monitoring of systems, unidentified bias (偏见) might make decisions continue for a long time that cause
All too often, data sets are incomplete and the sample represented in the data set does not
Bias resulting from AI algorithms themselves, or algorithmic bias, is equally

2 . Climate experts have warned about the many ways a warming planet can negatively affect human health.
One long-held prediction that appears to be coming true — according to the results of a study recently published in Nature Scientific Reports — is how climate change might enhance
Vibrio vulnificus (创伤弧菌) flourishes in salty or brackish waters above 68℉. Infections are currently rare in the U.S., but that’s likely to change. Using 30 years of data on infections, scientists at the University of East Anglia in the U.K. found that Vibrio vulnificusis
“We’re seeing the core
Based on the latest data on how much the world’s water and air temperatures will rise, the scientists predict that by 2081, Vibrio vulnificus infections could reach every state along the U.S. East Coast. Currently, only about 80 cases are reported in the U.S. each year; by 2081, that could go up to over three-fold, the authors say.
Such a proliferation could have serious health consequences. Vibrio vulnificus kills approximately 20% of the healthy people it infects, and 50% of those with weakened immune systems. There is little evidence that antibiotics can
Warming sea temperatures aren’t the only reasons behind the rise of Vibrio vulnificus. Hotter air also draws more people to the coasts and bays, bringing them into closer contact with the bacteria.
“The bacteria are part of the natural marine environment, so I don’t think we can
