A sticker paying tribute to Bianchi will be made available to all F1 drivers in Hungary this weekend, courtesy of the Grand Prix Drivers' Association.

World champion Lewis Hamilton has asked his Twitter followers to help  with ideas for his own sticker in memory of Bianchi.

Manor driver Will Stevens tweeted: Arrived in Hungary for what's going to be an emotional weekend, but we race on! That's what we do and what Jules would want! #JB17 #CiaoJules."

Lotus's Romain Grosjean, meanwhile, posted an image from "beautiful Budapest".

At last weekend's British Grand Prix they were clearly the second quickest car, decisively ahead of the Ferrari, until the rain came - and that puts them back where they were at the end of 2014.

They were leapfrogged over the winter by Ferrari, after the Italian team made a major improvement to their engine and a more subtle one to their car.

But a significant upgrade package introduced by Williams in Austria, the race before Silverstone, and then developed further for Silverstone, has put Williams back in the game.

Considering the resources they are working with - a budget of no more than half of that of Mercedes and Ferrari - that is a remarkable achievement.

And it gives them a strong foundation to head to the next race in Hungary on 24-26 July with every confidence that they can finish at least third in the championship again, if not potentially think about challenging Ferrari for second.

That will put them in a much more comfortable position financially going into 2015 and give them the chance to keep building on the revival they have been going through since the start of last season.

That's the positive. The negative is that Williams will have come away from Silverstone a little bit disappointed about both their result and their handling of the race on the way to it.

They were running one-two for the first 19 laps but they ended upfinishing fourth and fifth, having been leapfrogged not only by the two Mercedes cars but also Sebastian Vettel's Ferrari.

The star told the BBC another actor had once asked him for advice on whether they should take drugs for a role.

"Someone came to me and said, 'I'm going to play a drug addict - should I try the drug?' and I was like, 'no'," he said.

Gyllenhaal has dramatically lost weight for some of his roles, but said it was "with a watchful eye of an expert".

The actor shed most of his body fat for his current role in boxing movie Southpaw, out this week.

A gruelling training schedule saw him work out for six hours every day for six months to get down to 175lbs (79kg) - 15lbs (7kg) less than his normal weight.

For his Bafta-nominated role in last year's Nightcrawler, Gyllenhaal dropped 30lbs (13.6kg) for the part of gaunt paparazzo Lou Bloom.

He previously admitted he lived on a diet of kale salad and chewing gum, while running 15 miles every night to get into character.

The actor is not alone in dramatically changing his body shape for roles.

Christian Bale lost 63lbs (28.6kg) in four months for his part in 2004 film The Machinist, and Matthew McConaughey lost 38lbs (17kg) for his Oscar-winning Dallas Buyers Club role.

"When I did Nightcrawler I went to a doctor first," Gyllenhaal said.

"It wasn't like I was doing what Christian did in The Machinist, but I was very careful about it. It affects your body, but I try to be as safe as I can. Sometimes things get a little dangerous, but you always have to be mindful.

"There tends to be a narrative of actors taking risks that I think is dangerous to put out there, particularly as young actors thinking about [their] craft," he added.

"There's a fine line [about having a craft and a technique, but] you have to know that these things are done with preparation."

In 2013, Tom Hanks revealed past film roles which involved him having to manipulate his weight contributed to him developing Type 2 diabetes.

He told the BBC at the time he had ruled out future roles requiring drastic weight gain following his diagnosis.

"I've talked to a number of actors who have gained weight for roles and - just out of the sheer physical toll on one's knees and shoulders - no-one wants to do it again," he said.

A day earlier the two sides exchanged fire near the border, with one soldier killed and two more injured.

Turkey is to let the US carry out air strikes against the Islamic State group from a key military base near the Syrian border, US officials have said.

Turkish police also launched raids to arrest suspect IS militants on Friday morning in more than 100 locations in Istanbul.

The raids were carried out in 26 districts of the city and involved 5,000 officers. Members of the the outlawed Kurdistan Workers' Party (PKK) were also arrested.

A statement released by Prime Minister Ahmet Davutoglu's office said that F-16 jets had hit three IS targets in Syria.

The decision to carry out the attacks was taken at a security meeting called after Thursday's border clashes.

Turkish state TV said that the jets had not violated Syrian air space as they attacked the border town of Havar.

The US is expected to step up bombing raids against IS after reaching an agreement with Turkey to use the Incirlik airbase.

The agreement was finalised in a phone call between President Barack Obama and his Turkish counterpart Recep Tayyip Erdogan on Wednesday. It was confirmed by US officials speaking on condition of anonymity.

The use of the Incirlik airbase broadens the US military's ability to strike IS targets - one US official told the New York Times it was a "game changer".

Once used in raids against former Iraqi leader Saddam Hussein, the base is near to Turkey's long border with Syria, and significantly narrows the distance to the IS stronghold of Raqqa.

The announcement was made as Sharknado 3: Oh Hell No! premiered on US TV on Wednesday on the Syfy channel.

It ended with a piece of space shuttle hurtling towards April, played by Tara Reid, and the caption: "You decide if #AprilLives or #AprilDies".

Sharknado 3 will premiere on Syfy in the UK on Thursday.

As the film reached its cliffhanger, a voice-over informed US fans they would find out the outcome of the Twitter vote and April's fate in a fourth instalment of the franchise.

"Now's your chance to be part of Sharknado history," it said, "You decide if April lives or April dies.

"Her fate will be revealed in Sharknado 4. Because we're not done yet!"

Reid confessed the twist came as a surprise to her too, telling the Hollywood Reporter: "That was a shocker! I didn't expect that!"

"I think that's going to be a big turning point for the franchise. It gives it some excitement, and it's giving the fans a chance to interact.

"No matter what happens, I'm proud to be a part of this phenomenon."

After the first two films saw a tornado of sharks hitting first LA and then New York, Sharknado 3 sees the action moving to Washington and Florida.

The made-for-television disaster film also stars Ian Ziering as Fin and David Hasselhoff as Fin's dad, as well as cameos from Jerry Springer, Bo Derek and former X Factor stars Jedward, who recorded the theme song.

The Sharknado franchise has taken social media by storm, with the first two films generating more than a billion tweets between them. Sharknado producer, Chris Regina, hopes this latest stunt will prove just as engaging.

"I'm hoping that we're going to break the internet this time with the "April lives, April dies" at the end," Regina told Hollywood Reporter.

"I think it's going to be precedent-setting. I can't think of an instance where another network has done something of that nature at the end of an event. Hopefully it's a TV first."

But despite fans' interest in the franchise, it has yet to win over the critics.

"Having now watched "Sharknado 3: Oh Hell No!" I find myself in the position of having to write about it. And I am not sure which is worse, really, or even how to proceed," said Robert Lloyd, writing in the LA Times.

The California Supreme Court rejected his petition to review the case brought by Judy Huth - meaning her lawyers can now question Mr Cosby under oath.

The 78-year-old is facing a string of sexual assault accusations dating back decades.

He has always maintained his innocence and has never been criminally charged.

Ms Huth alleges that Mr Cosby plied her with alcohol before sexually assaulting her.

Her lawyer, Gloria Allred, described it as a "major victory" and says she intends to take a sworn deposition from the comedian within the next month.

Earlier in the week, the LA police department confirmed that it was investigating "certain complaints against him".

Court documents relating to the case brought in 2005 Andrea Constand - an employee at Temple University in the 1970s - were published earlier this month, after the Associated Press news agency applied to a judge to have the sealed papers made public.

They revealed Mr Cosby had admitted obtaining Quaaludes from several doctors to give to women before sexual encounters, but did not take them himself.

Mr Cosby is now suing Ms Constand for breaching a confidentially agreement after the New York Times obtained a full copy of the deposition.

Dozens of women have accused the comedian of sexually assaulting them but most of the claims are barred by statutes of limitations. They restrict the length of time in which legal actions can be taken after an alleged crime has been committed.

The accusations, which Mr Cosby has described as "fantastical" and "uncorroborated", have led to some of his stand-up shows being called off and the cancellation of some TV projects.

Muslim convert Adam Brookman said he travelled to Syria last year to do humanitarian work, local media said.

Police have not named the returning man but confirmed an Australian involved in the conflict had turned himself in.

Mr Brookman would be the first person to return from Syria or Iraq since Australia made it a crime to assist militant groups in the Middle East.

He may face arrest when he arrives at Sydney airport.

The Melbourne nurse told Fairfax Media in May that he had travelling to Syria in 2014 to use his nursing skills to help people caught in Syria's civil conflict, but was then was forced to help IS.

The Australian Federal Police (AFP) said the man's return from Syria, via Turkey, was being managed "in co-operation with relevant local authorities".

It said he had not been charged but was under investigation for his activities in Syria.

Under Australia's Foreign Fighters legislation, it may be enough to simply be in Syria or Iraq to face charges.

The legislation has made it easier to ban terrorist organisations.

It also strengthened the offences of training with, recruiting for and funding terrorist organisations and made it easier to prosecute foreign fighters by making it illegal to travel to a declared area overseas.

In December, 2014, Australia proscribed travel to Syria's Raqqa province, which is held by IS.

According to the government, at least 100 Australians are fighting with terror groups in the Middle East, and another 150 people in Australia are known to be supporting such groups.
