Police received information nearly immediately after the killing. It took Las Vegas police 27 years to make an arrest

For years, US law enforcement officials blamed their failure to solve hip-hop star Tupac Shakur’s murder on the lack of cooperation from key witnesses, and on gang members’ “snitches get stitches” culture.

But testimony in a much-delayed murder trial, which concluded this week, almost 30 years after Shakur’s death, highlighted just how much law enforcement officials knew about the shooting, and how early.

We all know tiredness can lead to hunger, and vice versa. But there are so many other ways our habits in these areas are linked. Here are some easy tweaks to help us feel properly refreshed

A study published in the journal Nature Health last month found that food choices and meal timings have “immediate and measurable effects” on sleep. It was just the latest in a growing body of research into the link between diet and rest. Here is the latest science on what to eat for better sleep – and how sleep deprivation can affect your dinner the next day.

Bandleader Femi Koleoso brings together the England and Arsenal star, the musician and the artist to discuss adversity, creativity and Black British culture

• ‘On the other side of pain there can be renewal’: Ezra Collective’s Femi Koleoso on reasons to hold onto hope
• ‘Like painting with light’: photographer Temi Adegbayibi on capturing the energy of music
• My cultural awakening , featuring Ezra Collective

Femi Koleoso I wanted to bring together people who inspire me and whose work I think evokes hope and joy. Yinka, the first time I saw your work I thought: this is exactly what joy looks like – it’s bold, colourful and the perfect embodiment of that feeling. Leona’s music has brought me joy ever since hearing you when you were on The X Factor. You’re one of the most iconic Black British singers we’ve ever had. With you, Eberechi, your transfer to the Gunners meant a lot to a lot of Arsenal fans, but personally it was a really beautiful way of seeing that things do work out for the good people. Can you tell me about your journeys to where you are now?

Leona Lewis I grew up in Hackney and I was surrounded by music because my dad was a DJ. He had a million records he would play all the time. I gradually discovered people like Whitney Houston, Chaka Khan and Oleta Adams mainly through my dad and I got really drawn to powerful female singers. I started singing all the time. When I was at school, I had a hard time because I was bullied – singing and writing music became a way to find my voice, my joy and my confidence. From then, I knew music was what I was going to do with my life: I didn’t know how I would get there but I knew I had to. It’s interesting that you do a lot of youth work, Femi, because I went to a lot of youth groups in north London while I was getting into music and then from 14 to 17 I enrolled in the Brit School. It helped me establish my voice and since then I’ve always been obsessed with music and it’s become my therapy: my joy, my pain, everything.

More than 400 competitors battle windy conditions on Easdale, a year after tampered-with stones made headlines

“Want to touch it?” Jonny Jennings asked, clutching the World Stone Skimming Championship trophy in his arms as he waited for the ferry. The mind games from the 2025 men’s champion had started hours before this year’s competition had even begun. The 38-year-old had travelled from Kentucky to Easdale island just off the west coast of Scotland to defend his title. He was not giving it up without a fight.

On Saturday, more than 400 of the world’s best stone skimmers descended on the tiny island in the Inner Hebrides, normally home to just 60 residents. From Argentina to India, Hong Kong to Jamaica, more than 30 countries were represented, ferried over in groups of 10 from the mainland.

A Dr Seuss-style story written in seconds alerted me to the power – and perils – of the technology. But how can children embrace it without forgetting core skills?

When I was growing up, my dad and I often talked about a story we wanted to write together. It was called “The Day Nobody Went to Disneyland”. One day, the story goes, the weather is so perfect that everyone in the world decides to stay away from Disneyland because they expect it to be far too busy. But my dad, who has the same thought as them, sees the disappointment on my face that morning – and decides to risk it. We set off. And when we arrive, the park is completely empty. Nobody else was brave enough to visit. We have everything – the rides, shows, food – to ourselves.

I loved the idea of writing that story. But, as so often happens, we were too busy to do anything about it. Life ran away from us. I grew up, and we both forgot about it.

Leon Panetta tells Guardian US is risking ‘forever war’ and says Pentagon ‘turmoil’ sending message of weakness

Donald Trump’s war with Iran is likely to drag on for another six months, Leon Panetta, the former US defense secretary, has warned, as the US president struggles to find his way out of the controversial conflict.

Panetta declared in an interview that the war with Iran – launched by Trump over six months ago – risks becoming another “forever war in the Middle East”, with no clear end in sight.
