SAN FRANCISCO--(BUSINESS WIRE)--Jun 6, 2023--

Artificial intelligence (AI) can generate Caucasian faces that seem more realistic than actual human faces, according to a new study. As per the research, published in Psychological Science and led by experts at the Australian National University (ANU), more people thought the AI-generated white faces were human than the faces of real people. The study found, however, that the same did not apply to faces generated of people of colour. If white AI faces are consistently perceived as more realistic, this technology could have profound implications for people of colour by ultimately reinforcing racial biases online Dr Amy Dawel According to senior author of the paper, Dr Amy Dawel, the reason for the notable difference between generated Caucasian faces and people of colour comes down to the fact that AI algorithms are trained disproportionately on white faces. Dr Dawel said: “If white AI faces are consistently perceived as more realistic, this technology could have profound implications for people of colour by ultimately reinforcing racial biases online. “This problem is already apparent in current AI technologies used to create professional-looking headshots. “When used for people of colour, the AI is altering their skin and eye colour to those of white people.” Researchers found when it comes to AI “hyper-realism”, most people did not realise they were being fooled. Study co-author and ANU PhD candidate Elizabeth Miller said researchers found that most of the study participants who were most confident that their answers were correct paradoxically thought that the AI faces were real. She said: “This means people who are mistaking AI imposters for real people don’t know they are being tricked.” The researchers were also able to discover why AI faces are fooling people. Although there were still physical differences between the AI and human faces, study participants still managed to misinterpret them. Dr Dawel revealed more in-proportion faces were typical signs that AI had generated a face. However, people mistook it as a sign of humanness. She added: “We can’t rely on these physical cues for long. AI technology is advancing so quickly that the differences between AI and human faces will probably disappear soon.” She said this could have profound implications regarding online misinformation and identity theft. Dr Dawel urged public transparency around AI so society can identify issues with the technology before they become more significant problems. “Given that humans can no longer detect AI faces, society needs tools that can accurately identify AI imposters,” she said. “Educating people about the perceived realism of AI faces could help make the public appropriately sceptical about the images they’re seeing online.” Read More AI among the biggest threats to the UK, cyber security agency warns Meta faces renewed criticism over end-to-end encryption amid child safety fears Call of Duty launch sparks record traffic on broadband networks Crypto investment fraud warning issued by major bank Council investigating extent of cyber attack that affected website and systems Setback for Ireland as EU legal adviser recommends revisit of Apple tax case

A new planet has been discovered and apparently it is pretty fluffy - like candy floss. The exoplanet, WASP-193b, was discovered 1,232 light-years away and while it's nearly 50 percent bigger than Jupiter, it's light and fluffy making it as dense as the sweet treat. According to a team led by astronomer Khalid Barkaoui of the University of Liège in Belgium, the planet orbits a Sun-like star named WASP-193. This star is around 1.1 times the mass and 1.2 times the radius of the Sun and is very close to the Sun in temperature and age. The planet orbits the star around once every 6.25 days. Barkaoui and his colleagues also found its radius is around 1.46 times the radius of Jupiter. But its mass is incredibly small by comparison: just 0.139 times Jupiter's.

This is a lot less dense than other planets like Jupiter and Earth. And as a point of comparison, cotton candy has a density of 0.05 grams per cubic centimeter which is why they made the link. There are few other examples of a planet like this existing but its close proximity to a star may give an indication as to how it came to exist as its heat is likely to have warmed up the planet's puffy atmosphere, which is mostly made up of hydrogen and helium. This state of the planet is only set to last for around a few ten million years as the temperatures and winds emitted from the star are only likely to strip back the atmosphere further. Due to this scientists cannot fully recreate or determine what is causing WASP-193b's unique atmosphere but is it likely to be a continued source of study to try and determine the cause of this phenomenon. You probably won't find this planet sold at fairgrounds any time soon though. Have your say in our news democracy.
