Flower power: How plants bounce back after crushing blows

Flower power: How plants bounce back after crushing blows

Science
Some flowers can recover with remarkable speed after a major accident, such as being walked upon by humans.Scientists found that species including orchid and sweet pea could re-orient themselves in 10-48 hours after an injuryThese plants are able to bend, twist and reposition their stems to ensure that they reproduce. But others such as buttercups fail to bounce back after damage.The remarkable abilities of some flowers to recover quickly from serious injury, have been previously overlooked by science, say the authors of this new work. Researchers looked at 23 native and cultivated flower species in the UK, Europe, Australia and North and South America. They examined spe...

SpaceX blows up rocket to test astronaut escape system

Technology
SpaceX has blown up a rocket to test an astronaut escape system as part of the company's final trial before it can fly manned missions. A Falcon 9 rocket lifted off from Cape Canaveral on Sunday - a day later than originally scheduled due to bad weather -and was attached to a Dragon crew capsule containing two mannequins. To test the emergency abort system, the capsule boosted off from the Falcon 9 just over a minute later around 12 miles above the Atlantic Ocean.The rest of the rocket then deliberately shut off its engines and descended into a fiery blast.The remaining capsule, which SpaceX hopes will eventually carry astronauts Doug Hurley and Robert Behnken to the International Space Station, then released several parachutes and splashed down into the Atlantic Ocean. ...

SpaceX Starship prototype blows its top

Science
SpaceX's Starship rocket prototype experienced a major failure during pressurisation testing on Wednesday.A video from the scene in Texas showed the top part of the vehicle rupture.Cryogenic propellants that were being loaded at the time dispersed across the Boca Chica facility in a huge cloud.The US company bills Starship as an all-purpose transportation system of the future. It will be used to ferry people and cargo off Earth, and to destinations around the globe.The Mk-1 prototype was due to begin practice flights to an altitude of 20km in the coming weeks. In a tweet, SpaceX CEO Elon Musk said that could no longer happen and the ship would be retired.Development work is already being directed at another prototype, labelled th...

Amir Khan vs Billy Dib RESULT: Brit blows smaller man away with fourth-round knockout, calls out Manny Pacquiao

Sports
TOO STRONG It was a simple night's work for Khan Amir Khan floored Billy Dib twice to secure a fourth-round knockout on Friday night in Saudi Arabia. The Brit made his physical attributes tell against his overmatched, undersized, late-replacement opponent and put him away without any trouble. Getty The performance echoed Khan’s comeback win over Phil Lo Greco last year In the opening round, the size difference between the pair was blatant as super-featherweight Dib jumped up 17lbs to face welterweight Khan on short notice. Although nothing hugely significant landed from either man, it seemed to be only a matter of time. Come the second, this theory proved true as the Brit decked the Australian with a big left hook. Dib survived the
