Lizzie Deignan takes second behind Anna van der Breggen in Amstel Gold Race

  Lizzie Deignan takes second behind Anna van der Breggen in Amstel Gold Race Great Britain's Lizzie Deignan finished second to team-mate Anna van der Breggen as the women's Amstel Gold Race in Holland returned to the calendar for the first time in 14 years. Olympic road race champion Van der Breggen attacked with 7km, and one daunting climb up Cauberg, left and finished 55 seconds clear in her home race.Deignan was in a chasing pack of five at the business end of the 121km route and came out on top in a bunch sprint for the line.There was a rare tie for third behind her, as Orica Scott's Annemiek van Vleuten and WM3's Katarzyna Niewiadoma could not be separated.

We all know what is (sorta) the world ' s smallest road car . What about racers ? There are lots of oddly-proportional race cars out there, and perhaps none are odder than the Mk. 1 Shadow Can Am car from 1970.

  A race between the world’s smallest cars is about to begin © Provided by Quartz The racers have snazzy names: Green Buggy, Swiss Nano Dragster, Windmill, Dipolar Racer, Ohio Bobcat Nano Wagon, and Nims-Mana Car. Each car will spend some 36 hours speeding around a challenging French racetrack. There will be drama, twists, and lots of turns.

But what makes this race unusual is that the cars don’t have wheels, motors, or even fuel. The drivers can only watch the action on a computer screen, because they are a billion times bigger than the cars. Welcome to the inaugural NanoCar Race.

The cars are single molecules, the track is made of gold, and the environment will be chilled to near absolute zero (about -270°C or -450°F). The only way to move the racers is via a series of electric shocks, with each jolt pushing them about 0.3 nanometers—less than a thousandth the width of a human hair. To win, the cars have to “run” for 100 nanometers.

Vettel battles to second 2017 victory in Bahrain

  Vettel battles to second 2017 victory in Bahrain Sebastian Vettel clinched his second victory of the season at the Bahrain Grand Prix after a superb race strategy saw him triumph over polesitter Valtteri Bottas and championship rival Lewis Hamilton in the race. Bottas got a good start off the line and managed to retain the lead into the first corner, however, Hamilton bogged down and lost second place to Vettel on the opening lap. The opening laps saw the top five cars maintain within three seconds of each other, proving that the cars can follow each other fairly closely in the early stages of the race. Max Verstappen was unlucky to crash out on lap 12 with brake failure after a pit stop to try and undercut the leading Mercedes following Vettel’s initial stop. On the following lap, Carlos Sainz collided into the Williams of Lance Stroll as he exited the pitlane in an attempt to pass the Canadian into Turn 1, the safety car had to then make an appearance to retrieve the stricken cars. A five-second penalty was handed to Hamilton as he held up Daniel Ricciardo in the pit entry as the safety car was called, this meant a huge strategy conundrum for the Mercedes team. After swapping positions on lap 27 to allow Hamilton tsome free air, the positions reversed after both drivers made their pitstops and Hamilton served his penalty. Hamilton made a late pit stop in an attempt to chase down Vettel, however, the gap was too large for the Briton to make up.

The only way to follow the action is with a sophisticated scientific instrument known as a scanning tunneling microscope (STM). After each car gets an electric jolt, the STM will take three minutes to scan the race track and tell the contestants whether or not their cars moved.

This week, the six contestants will battle it out in trials to determine the top four. The final competition will begin on April 28. Because the race will be too slow to watch in real time, the organizers will create a short animation every hour and post it online.

The aim of the race is not to win money or fame, but to get people excited about nanotechnology and molecular machines. The 2016 Nobel Prize in chemistry went to pioneers in the field, but public awareness about the potential of the technology remains low.

The race should provide valuable scientific insights for experts, too. A better understanding of the physical characteristics of molecular machines could help identify new applications such as relaying information or making chemical reactions go faster.

Bottas remains positive despite second row start in Russia .
Valtteri Bottas is remaining positive ahead of the Russian Grand Prix despite narrowly missing out on pole position as Ferrari locked out the front row. The Finn looked in contention for pole throughout the qualifying session but a mistake at the final corner saw him pipped to pole by less than a tenth of a second. Speaking after qualifying, Bottas said: “I think we can see Ferrari were quicker today. We were close in the end, but not close enough. “All weekend they’ve had the upper hand and they’ve managed to extract more out of the tyres. They are looking very strong here and, as we’ve seen so far this year, Ferrari have a good race pace and we expect it to be the same tomorrow. Bottas, though, believes that the work the team carried out overnight will be critical to the performance in the race. With a one kilometre run down to Turn 2, he is keen to bounce back from his defeat in qualifying and beat the Ferraris into the lead at the start of the race. “We made an improvement from yesterday,” Bottas added. “It wasn’t quite enough but I think the changes we made overnight should help us in the race. “Tomorrow is where it counts and starting on the second row is still not a bad place to begin the race. There’s a very long run down into Turn 2 and a lot of slipstreaming. Ferrari is ahead today, but hopefully not tomorrow.
