Can Americans spell the National Spelling Bee's winning words? The BBC challenged Americans to spell words used in the last three Scripps National Spelling Bee competitions. Shrey Parikh, a 14-year-old, won the competition this year after correctly spelling 32 words in a 90-second lighting round tiebreaker. He defeated 12-year-old Ishaan Gupta, who spelled 25 words correctly. Parikh won out against 247 spellers competing in the annual contest, aged between nine and 15, taking home a $52,000 (£39,000) cash prize.

Fans react to Stephen Colbert's final show Fans lined up outside the Ed Sullivan Theater one last time for "The Late Show" as Stephen Colbert prepared to host his final episode, marking the end of the franchise's 33-year run on CBS. The network announced last summer that the show would end, calling it "purely a financial decision against a challenging backdrop in late night. Colbert took on the show on September 2015 after David Letterman retired from the role he'd held for 22 years. Rescuers removed the vehicle from near the shoreline and police arrested the driver, who was attempting to use the vehicle's wade mode. As part of the ongoing investigation into the crash that killed 14 people, officials released footage showing the engine detaching during takeoff.

An escaped tiger believed to be owned by Germany's Tiger Queen has been shot dead by police after attacking one of its keepers, according to local media reports. Police say a 73-year-old man was seriously injured after being attacked on Sunday while he was inside the animal's enclosure, located in a privately-owned facility on the outskirts of the German city of Leipzig. The tiger escaped the enclosure and was found shortly after by armed police, who shot and killed the animal. The site of the enclosure is believed to be owned by controversial trainer and private owner Carmen Zander, who describes herself as Germany's Tiger Queen. The animal was one of eight big cats kept at the industrial site near the German town of Schkeuditz, according to local media.

More than 4,000 police officers have been deployed to London, as crowds start to gather for two rival protests in the capital. Police will use drones, police horses and dogs and have armoured vehicles on standby. Officers will also manage a so-called sterile zone between the Unite the Kingdom march, organised by far-right figure Tommy Robinson, and a pro-Palestinian demonstration. The Metropolitan Police has called it one of the most significant policing operations in years. In addition to the protests, tens of thousands of football fans are expected at Wembley Stadium for the FA Cup Final on Saturday afternoon.

The Metropolitan Police has warned that it is preparing for potential violence and hate speech crimes across two protests in London this Saturday. More than 4,000 officers will be drafted in to police the rival events - possibly one of the largest protest deployment in decades - amid fears that far-right demonstrators could clash with pro-Palestine marchers if the two groups are not kept apart. In addition, tens of thousands of football fans are also expected at Wembley Stadium for the FA Cup Final, adding further pressures on the capital's police. Scotland Yard said the risks meant it had to impose the highest degree of control. Measures the Met is planning include the first authorisation of live facial recognition cameras at a demonstration.

A man has been charged after allegedly threatening Andrew Mountbatten-Windsor during an incident near his home on the Sandringham Estate in Norfolk. Norfolk Police earlier said a man was arrested shortly after 19:30 BST on Wednesday after officers received a report of a man a behaving in an intimidating manner in Wolferton. The Daily Telegraph reported Mountbatten-Windsor was threatened by a balaclava-clad man while out walking his dogs and fled to his car along with his security. Alex Jenkinson, 39, of Stowmarket, Suffolk, has been remanded in custody and is due to appear at Norwich Magistrates' Court on Friday. Police said he has been charged with two counts of using threatening, abusive or insulting words or behaviour to harass someone or cause alarm or distress and failing to provide a specimen of blood in custody.

Driverless cars are becoming more common in some California cities, but when the autonomous vehicles violate traffic laws, police haven't been able to ticket them - until now. The state's Department of Motor Vehicles (DMV) has announced new regulations on autonomous vehicles (AVs), including a process for police to issue a notice of AV noncompliance directly to the car's manufacturer. The new rules, which will go into effect 1 July, are part of a larger 2024 law that imposed deeper regulation on the technology. There have been a number of reports of the cars breaking traffic laws, including during a San Francisco blackout last year. The California DMV is calling the new rules the most comprehensive AV regulations in the nation.

Figure 4: Impact of the proportion of injected noise for learning Paragraph Embeddings on XSum dataset. PPLint and the PPL of the generation obtained from training PLANNER on the corresponding z at different noise level. We observed when the value of p is within (0, 0.7), there Performing a grid search on each task using diffusion models is an expensive process. However, it has been observed that an increase in the value of p leads to a deviation between the two. This could be attributed to a higher conversion error that occurs when p is excessively large. A.2 Selection of number of latent code k The parameter k determines the number of latent codes used to represent a paragraph and therefore controls the compression level. Latent codes with smaller values of k are easier to model using the diffusion model, but may struggle to accurately preserve all the information in the original text. Additionally, smaller values of k offer computational efficiency as the sequence length for the diffusion model is k. To determine the best set of latent codes, we conducted experiments using three different methods: 1) selecting the first k hidden vectors, 2) selecting the last k hidden vectors, and 3) selecting interleaving hidden vectors, one for every L k hidden vectors. The results of the ablation study are presented in Table 5. Based on our findings, we observed no significant difference among the different choices, so we opted for option 1). Furthermore, we discovered that increasing the value of k does not lead to a dramatic improvement in performance. To balance between efficiency and performance, in most of our study we only use k =16 Setup BLEU_clean BLEU_robust First k (k=16) 79.59 43.17 A.3 Reconstruction, denoising and interpolation examples In Table 6, we present examples that demonstrate the adeptness of the trained Variational Paragraph Embedder in providing clean and denoised reconstructions. Additionally, we showcase interpolation results (Table 7, 8) derived from two random sentences in the hotel review dataset. The interpolated paragraph is usually coherent and incorporates inputs from both sentences, characterizing the distributional smoothness of the latent space.

Japan zoo staffer allegedly dumps wife's body inside incinerator A popular Japanese zoo has delayed its opening for the summer season after an employee told police he had disposed of his wife's body in the zoo's incinerator, local media reported. Asahiyama Zoo in the northern city of Asahikawa was supposed to welcome visitors on Wednesday in time for Japan's Golden Week holiday period, after completing a three-week maintenance break. But the city government says the zoo will now remain closed until Friday as investigations continue. Last week, police searched the zoo grounds after the employee told them he had disposed of his wife's body in the zoo's incinerator, local media reported. The incinerator was used to dispose of animal carcasses when they died.

A recent attack on Sam Altman's home and OpenAI offices has put corporate security under renewed scrutiny. Records reveal how much some tech firms spend to arm up. Elon Musk called violent crime in San Francisco " horrific " and moved the offices of his social media business X outside the city in 2024 because of safety and business considerations. Other local tech companies have attempted to address their security concerns by partnering directly with cops. Airbnb and Salesforce are among businesses that for years have contracted San Francisco police to protect their offices on a regular basis, according to public records obtained by WIRED.
