A man who has spent 'millions' trying to biologically lower his age in order to live longer reveals he drinks alcohol every morning for breakfast. Bryan Johnson, 45, has the 'biological age' of an 18-year-old, and is projected to live to be 200. He made the shocking confession on Steven Bartlett's Diary Of A CEO podcast, where he told of how his final meal of the day is done by 11am.

Ever wondered why people say they can smell rain before it rains? They are not pulling your leg - there is real science behind it. It is all because of petrichor, made up from the Greek words "petra", meaning stone, and '"ichor", which refers to the golden fluid that flows in the veins of the gods in their mythology. It basically means the the "smell of rain" with the phrase coined by Australian scientists Joy Bear and Richard Thomas in 1964. Jeff Weber, a meteorologist with the University Corporation for Atmospheric Research Unidata Program Center told the Mirror: "Petrichor is caused by oils derived from plants, primarily leaves, that accumulate over dry periods. These oils settle into soils or onto pavement over time and are released into the atmosphere by being disturbed by rainfall." According to the Met Office, the reason people claim to smell rain because it comes is because "when a higher humidity is experienced as a precursor to rain, the pores of rocks and soil become trapped with moisture forcing some of the oils to be released into the air".

This is when raindrops landing on soil "trap tiny air bubbles on the surface which then shoot upward" and "burst out of the drop throwing aerosols of scent into the air where they are then distributed by the wind". The smell is produced by a soil bacteria which releases a chemical called geosmin, which provides an "earthy", musky or fresh aroma. Before it rains, a person might be able to smell the scent of ozone, or O3, which is a naturally present gas in the atmosphere which gets its name from the Greek word 'ozein', or smell. It sometimes indicate that a storm is on the way because pockets of gas are pushed down to ground level by winds. This means that those who are sensitive to the smells will likely be able to pick them up. So now you know. Have your say in our news democracy.

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.
