Who doesn't love a good ol' optical illusion? Well apparently, if you can spot the second tiger in this trippy image, you're in the top one per cent of intelligent people – and it's much more difficult than you think. Asides from the obvious striped cat in the middle of the jungle, there's another "hidden tiger" that's left people scratching their heads. Sign up to our free Indy100 weekly newsletter Take a look: Found it yet? If you've spotted the hidden tiger in this image, then (apparently) you're smarter than most people. Discussing the importance of optical illusions to better understand our brains, scientists Kim Ransley and Alex O. Holcombe, of the University of Sydney told The Conversation: “Visual illusions show us that we do not have direct access to reality,” “They can also provide an inkling of the mental processing that delivers our experience of the viewable world. “Indeed, it is the processing happening inside our brains that is the basis for many illusions. “Rather than delivering information from our eyes in nearly raw form as a camera would, the brain tries to determine what is actually out there. “When the information entering the eye is ambiguous, the brain must make educated guesses.” Still need help? Take a closer look at the tiger itself. More specifically, its torso. The reason the optical illusion is so difficult to crack is because there is no image of a second tiger. In fact, it's the three words: "THE HIDDEN TIGER" stretched across its stomach and back leg. For the most part, optical illusions are a bit of fun, but they also hold real value for scientists.

A nearly two-week manhunt for a dangerous murder convict Danelo Cavalcante came to an end on Wednesday as he was captured in Pennsylvania. Pennsylvania State Police are set to hold a press conference on the capture at 9.30am. For 14 days, Cavalcante managed to elude hundreds of law enforcement officers, including tactical teams in full combat gear, tracking dogs, cops on horseback and on aircraft. Pennsylvania State Police Lt Col George Bivens had credited Cavalcante’s upbringing in rural Brazil for his ability to hide in the vast wooded terrains in Chester County. The jailbreak on 31 August sparked fear among residents of the county’s suburbs, who were urged to keep their homes secure following a series of break-ins believed to be linked to Cavalcante. On 11 September, fears reached a fever pitch as Cavalcante stole a gun from a garage. Cavalcante managed to get ahold of clothing, food, and even stole a van that he used to drive more than 25 miles from his original hiding spot in Longwood Gardens. He was spotted multiple times throughout the 14-day ordeal and the sightings repeatedly forced law enforcement to expand their search perimeter and prompted three school districts and a popular botanical garden to close. Throughout his escape, Cavalcante showed up at the home of two former associates. Cavalcante escaped from Chester County Prison while awaiting a transfer to state prison. Last month, he was sentenced to life for murdering his ex-girlfriend. Chester County District Attorney Deb Ryan previously said that Cavalcante would not be returning to the county prison once he was captured. Cavalcante began his escape at around 8.50am on 31 August while other inmates in the exercise yard played basketball. He stretched his body to fit the length of a hallway and “crab-walked” onto the roof. He then climbed over razor wire and jumped from the roof. It was only nearly an hour later that correction officers realised an inmate was missing during a head count. The prison was locked at 9.50am and the 911 centre was notified of the escape 10 minutes later. Chester County Prison acting warden Howard Holland said that Cavalcante’s jailbreak was similar to another inmate’s escape back in May. During that incident, a tower officer immediately reported the situation to prison staff and the inmate was apprehended within minutes. The officer tasked with surveilling the area during Cavalcante’s escape did not report the incident. He has been placed on administrative leave and his performance is being investigated by the state attorney’s office. Cavalcante killed his ex-girlfriend Deborah Brandao in front of her children in 2021. Prosecutors say Cavalcante killed Brandao to prevent her from telling police that he was wanted in a 2017 killing back in Brazil. Authorities believe he was trying to return to Brazil after Brandao’s murder before he was captured in Virginia.
