Your response to this baffling optical illusion could depend on where you grew up
Last year we covered the 'coffer' illusion, a visual riddling that was blowing/bending/frying/breaking the internet's collective mind. And like all the best illusions, it seems this one keeps on giving, as new scientific research has revealed that your perception of it could be influenced by one unexpected factor.
For the uninitiated, the coffer illusion depicts what appears to be a series of rectangles – but actually contains 16 circles. They're initially hard to spot, but once you've managed it, they can't be unseen (spoiler alert: they're in the gaps between the rectangles). How quickly you find the circles, though, could depend on where in the world you grew up.
As reported by the Guardian, a study led by Ivan Kroupin at the London School of Economics has explored how people from different backgrounds interpret the coffer illusion, found that "people in the UK and US saw it mainly in one way, as comprising rectangles – while people from rural communities in Namibia typically saw it another way: as containing circles."
So why the difference? The suggestion is that those hailing from western industrialised countries "are generally exposed to highly 'carpentered' environments, with lots of straight lines, right angles," whereas rural Namibians, for example, see the circles first because "their environments being dominated by structures such as round huts instead of angular environments."
"During the data collection, it was quite striking to see individuals immediately identify and describe features of an image - circles - which took all authors a significant amount of time to identify at all," the study explains, before going on to suggest different responses to the illusion could hint at larger visual discrepancies between people. "In sum, the world does not look the same to all of us—the present results show this at the very least. And it remains a possibility that such cultural variation exists even at layers of visual perception previously assumed to be universal."

What's Up With That? Why do some Columbus streetlights look blue or purple?
I'm curious about the blue streetlights on 23 near Lazelle Road. Are they a blue hue to keep people awake? To conserve energy? To hurt drivers' eyes? Total mystery to me. I have to admit, this week's "What's Up With That?" query truly had me stumped. After more than six years working in the news business in this market, I'm pretty familiar with most of the major goings-on in Columbus, Ohio, even if I sometimes have to tap a reporter on the shoulder to help me answer a question. But while I live just a few miles from the stretch referenced by this week's submitter, I was woefully unfamiliar with the infamous blue lights on State Route 23. I turned first to the Ohio Department of Transportation, assuming they managed the lighting along 23. But I was redirected to the Columbus Division of Power (a regular guest in this series), as that's in fact controlled by the city. (As reporter Jordan Laird told you while I was on glorious vacation, nothing is simple when it comes to Columbus boundaries.) Luckily, the city was able to get me a prompt response. Here's what I learned. As I said, I've not seen the blue streetlights myself. And while I am committed to this feature and its success, given it is summer and the sun doesn't go down until about an hour after my daughter has gone to bed, I didn't venture out to get a look. But George Zonders, public relations specialist for Columbus Public Utilities, knew exactly what our reader was talking about, and assured me it was not a tribute to Prince (or the artist formerly known as same). "This is an issue our Division of Power and other streetlight utilities across the country have encountered for several years now, and is specific to light-emitting diode (LED) lights. These lights have a natural light blue or purple hue; during the manufacturing process they are covered with a phosphor coating, which adjusts the color temperature to make the blue/purple light appear white. Over time, that coating can degrade and reveal the original color, which is most often reported as light purple. "Streetlight manufacturers have since addressed this problem, but because LED lights last so long (we are in the process of upgrading all of our lights to LED) our Division of Power occasionally still receives calls about purple lights around the city, and we expect that to continue. We began receiving reports about this location and another nearby (off South Old State Road) within the past few days, and we are preparing to replace those lights with new ones." It's not just a Columbus phenomenon. The same purple-ish hued streetlights have appeared nationwide, according to USA TODAY. If you, like our reader, find your eyes bothered by discolored streetlights, you need not suffer in silence. Zonders asked anyone who notices one (or another streetlight issue) to report it via 311: dial 311 or 614-645-3111, email 311@ or go online to I really loved answering this week's question because I learned something, about my own neck of the woods no less. I'm hoping to add some more queries to my roster that will similarly edify me, and our readers. Do you have a question you want answered? Email me at ekennedy@ or you can send your questions to newsroom@ ideally with "What's Up With That?" in the subject line. Thank you to the many of you who have already submitted questions; we're hard at work getting answers to them, and we look forward to hearing from more of you!

Road closures are 'shocking', councillor says
The closure of major routes in a city is "shocking and completely daft", a councillor says Roads in Bristol including Bath New Bridge in Temple Meads and the dual carriageway Passage Road in Henbury are closed for repairs. Mark Watson, the local councillor for Henbury and Brentry and the Leader of the Bristol Conservative Group, said: "Someone somewhere has not planned this properly. It's shocking. I'm not disputing the works need doing but if they waited a week, schools would be off. It is completely daft." Helen Godwin, mayor of the West of England, said the repairs will "lay the foundations for a better transport system overall for the West of England". More news stories for Bristol Watch the latest Points West Listen to the latest news for Bristol While Passage Road - in the north of the city - is closed southbound, traffic will need to follow the signposted diversion via Crow Lane, Henbury Road, and Falcondale Road for onwards travel. Pedestrians and cyclists will still be able to use the road. The works are needed to rebuild a section of the road because it was originally constructed with poor quality materials, the city council said. The work on Passage Road is happening while the Henbury transport scheme is being built - which has already seen widespread disruption in the area. Meanwhile, work to repair Bath New Bridge, part of Bath Bridges roundabout on the A4 Bath Road, has started on Monday. Its repair forms part of the council's £16m New Cut bridge's restoration programme that is restoring eight crossings over five years. Only one lane of the bridge can remain open while the repair work takes place, meaning significant delays are to be expected when heading into the city centre on the A4. From Monday, York Road will reopen one-way travelling from Bath Bridges roundabout towards Bedminster Bridges roundabout. Follow BBC Bristol on Facebook, X and Instagram.
