Toto Wolff has dampened expectations on Mercedes’ highly-anticipated upgrade for the next race in Imola despite Lewis Hamilton calling for a one-second upgrade after the Miami Grand Prix. After qualifying a lowly 13th, Hamilton finished sixth in Miami on Sunday with team-mate George Russell a respectable fourth - but still way out of Red Bull’s league after another one-two finish for the reigning world champions. While Hamilton insisted he needed a “second upgrade” worth around one second, Wolff believes the upgrade for Imola may not even be worth half-a-second, instead saying it will be a “good baseline”, adding: “I don’t think we’ll get there and suddenly we’re half a second faster and in the middle of a fight. We won’t.” Elsewhere, Max Verstappen sends a chilling warning to his title rivals, Wolff lambasts Hamilton’s Mercedes car after qualifying and George Russell criticises unusual pre-race introductions.

If you’re anything like us, the first coffee of the day is the only thing that can get us up on a morning – and it turns out, there’s real science behind it. Everyone knows that coffee can give us a welcome caffeine hit, but it’s now been revealed that the drink also gives us an extra ‘special boost’ too. Scientists have claimed that the act of drinking a cup of joe gives the body a lift, making us more alert, which can’t be replicated merely with caffeine. In fact, new research shows that drinking hot coffee activates additional areas of the brain. Sign up to our free Indy100 weekly newsletter Scientists from the University of Minho in Portugal and elsewhere looked into the effects of coffee outside of just caffeine content as part of a study – and they found that plain caffeine didn’t have the same impact. In fact, a cup of coffee also influenced working memory and goal-directed behaviour. “There is a common expectation that coffee increases alertness and psychomotor functioning. When you get to understand better the mechanisms underlying a biological phenomenon, you open pathways for exploring the factors that may modulate it and even the potential benefits of that mechanism,” study co-author Nuno Sousa explained. Experts said that drinking coffee actually increased the connectivity in the brain’s more advanced nerve network controlling vision, and other parts involved in working memory, cognitive control and goal-directed behaviour – something not found when participants only took caffeine. Researchers also said that if subjects wanted to not just feel alert but ready to go, caffeine alone might not do the job. “Acute coffee consumption decreased the functional connectivity between brain regions of the default mode network, a network that is associated with self-referential processes when participants are at rest,” study co-author Maria Picó-Pérez said. “The subjects were more ready for action and alert to external stimuli after having coffee,” she added.
