Ever wondered how optical illusions actually work? Wonder no more. A new study by University of Exeter visual ecologist Jolyon Troscianko, and neuroscientist Daniel Osorio from the University of Sussex in the UK has weighed in on the debate over whether we perceive things weirdly because of certain errors in the ways our brain processes colour, shade, and shape or because of our eye's function or the brain's neurological wiring. They reckon it is all in the eyes. The pair found ways our visual neurons – cells that process information coming in from the eyes – work, showing how they can affect our perception of patterns on different scales. "Our eyes send messages to the brain by making neurons fire faster or slower," said Troscianko. "However, there's a limit to how quickly they can fire, and previous research hasn't considered how the limit might affect the ways we see colour."

"Our model shows how neurons with such limited contrast bandwidth can combine their signals to allow us to see these enormous contrasts, but the information is compressed – resulting in visual illusions," said Troscianko. "The model shows how our neurons are precisely evolved to use every bit of capacity." Have your say in our news democracy.

Elon Musk’s X, formerly known as Twitter, slowed down access to rivals and news organisations, according to a new report. The company seemingly added a delay of as long as five seconds when people clicked on links to go elsewhere on the web, according to a Washington Post report. The delay was applied to a host of rival websites, including Facebook, Instagram and Bluesky. It was also used on the websites of news organisations that have been critical of Mr Musk, such as Reuters and the New York Times. Clicking a link on X to one of the affected websites resulted in a delay of about five seconds before the webpage loaded, the Washington Post reported, citing tests it conducted on Tuesday. Reuters also saw a similar delay in tests it ran. By late Tuesday afternoon, X appeared to have eliminated the delay. When contacted for comment, X confirmed the delay was removed but did not elaborate. Billionaire ElonMusk, who bought Twitter in October, has previously lashed out at news organizations and journalists who have reported critically on his companies, which include Tesla and SpaceX. Twitter has previously prevented users from posting links to competing social media platforms. Reuters could not establish the precise time when X began delaying links to some websites. A user on Hacker News, a tech forum, posted about the delay earlier on Tuesday and wrote that X began delaying links to the New York Times on Aug. 4. On that day, Musk criticized the publication’s coverage of South Africa and accused it of supporting calls for genocide. Reuters has no evidence that the two events are related. A spokesperson for the New York Times said it has not received an explanation from X about the link delay. “While we don’t know the rationale behind the application of this time delay, we would be concerned by targeted pressure applied to any news organization for unclear reasons,” the spokesperson said on Tuesday. A Reuters spokesperson said: “We are aware of the report in the Washington Post of a delay in opening links to Reuters stories on X. We are looking into the matter.” Bluesky, an X rival that has Twitter co-founder Jack Dorsey on its board, did not reply to a request for comment. Meta, which owns Facebook and Instagram, did not immediately respond to a request for comment.
