you go to sleep for four hours, and then i am going to personally wake all of you up. he's begun a major study of the effects of lack of sleep on the brain. so i joined volunteers at western university ontario, trying out his test, which anyone can sign up for online. they're designed to reveal how our brains are functioning — reasoning, memory, and decision—making. to demonstrate how tiredness may affect that, we stayed up until liam, and then had just four hours sleep. but all too soon... good morning, fergus. time to get up! we were about to repeat the brain tests we'd done the previous night. how are you feeling? err... i'm feeling... like i haven't had enough sleep. most of our scores went down compared to the night before.

how did you do this morning? worse. this was the worst you ever did? this was the worst ever, yes. 0h, kisses for your sister, that's really nice. but sylvie, whose daughters wake her several times a night, improved her score. maybe i've just gotten used to functioning on very little sleep. i have to be on as soon as my kids wake up. as for me... i finished and i've done quite badly! i also did the tests while having my brain scanned. after a normal night's sleep, my brain was functioning well. the bright orange blobs are areas of increased activity. and this is the scan done after four hours' sleep. there's not much going on. it's pretty clear there is much less activity in these areas of the brain that we know are crucial for things like decision—making, problem—solving and memory. so, our 24—hour culture could be having a serious impact on society.

those signing up to the world's biggest sleep study will help show the extent of the problem and reveal how much sleep we need for our brains to be at their best. fergus walsh, bbc news, ontario, canada. newsnight is coming up on bbc two. here's emily. tonight after grenfell we reveal the failures at the heart of the system which is meant to keep our homes safe from fire. but to a former housing minister. join me now on bbc two. here on bbc one, it's time for the news where you are. hello and welcome to sportsday — i'm hugh woozencroft. here's what's coming up this evening. heather watson wows at eastbourne as she beats the world number nine to reach round three. the british and irish lions have failed to impress

so far in new zealand — head coach warren gatland has now been labelled desperate by his opposite number. frank de boer is looking up — he's the new manager of crystal palace and says he wants their struggles to stop. good evening, just one week from now we'll be at wimbledon for the first day of the championships and the preparations are well under way. there's already been an encouraging win today forformer british number one heather watson who knocked out fourth seed dominika cibulkova at the aegon classic at eastbourne. she moves on to face russia's anastasia pavlyuchenkova next. paul garrity watched the action. heather watson's fortunes have been outshone of late by those of eastbourne residentjohn cantal. looking for form and with wimbledon

just around the corner the british number three was quick out of the blocks against the defending champion. dominika cibulkova by contrast was hesitant and reluctant to spend any time away from the baseline and watson took the first set 7—5. a world ranking slipped to 126, her opponent number six, set 7—5. a world ranking slipped to 126, her opponent numbersix, but the british player was running rings around her. cibulkova is known for her speed and aggression, but watson howe ran and outplayed her, soon arriving at match point. commentator: we play on, three match points have come and gone, cibulkova has broken back. no matter, a fourth match point duly arrived and cibulkova was beaten 7—5, 6—3. eight of the top ten began the eastbourne tournament and even if watson's progress is halted she has already received a huge boost of confidence to ta ke received a huge boost of confidence to take into wimbledon next week. paul geraghty, bbc news. i felt really good out there today,

playing the long match yesterday in the wind and those conditions set me up the wind and those conditions set me up really well for today because as windy today and i saw the ball a lot bigger, my serve was coming together. a good win for watson. and defeat for the british women's number two naomi broady who lost in three sets to the czech republic's kristina pliskova. broady won the second set on a tie—break but lost the decider 6—1. british men's number two kyle edmund was beaten in the first round of the men's singles at eastbourne by american donald young, ranked 47 in the world. edmund lost the first set but fought back to take the second 6—3 before losing the decider by the same score. there was some success though for marcus willis in the first round of wimbledon qualifying — the briton reached the third round at last year's wimbledon before losing to roger federer on centre court. he still has a chance of making this year's tournament proper after being slovakia's andrey martin, despite being ranked 241 places lower than his opponent.

willis now faces fellow briton liam broady — brother of naomi — in the next qualifying round. the first round is always tricky, a bit nervy at the start, he was serving very well, under pressure i served well and played a couple of good games to break. obviously happy with the win, i know i have more in me out there. get on the practice court and see howl me out there. get on the practice court and see how i play in the next match. you don't expect to go on your phone reading venues. at the same time dan likes to enjoy himself —— that news. he's obviously taken it too far this

time. he knows more than anyone else what he's done and he's got no one else to blame. it could be a pivotal week for the british and irish lions on their tour of new zealand. their defeat to the all blacks in the first test two days ago means the series will be lost with a repeat outcome in the second match in wellington this saturday. before then, the lions face another tough—looking game against super rugby side the hurricanes early tomorrow morning. warren gatland has been involved in one or two feisty exchanges with his opposite number steve hansen this week and things escalated again earlier today. our sports correspondent katie gornall is in wellington. after the british and irish lions we re after the british and irish lions were soundly beaten by the all blacks in auckland things have got heated between the two coaches ahead of the second test in wellington with the all blacks boss steve hansen calling warren gatland predictable and a little bit desperate. it was in response to gatland's comments about new

zealand's treatment of their scrum—half conor murray. he thinks murray was unfairly targeted and could have been potentially injured. predictable comments from gatland. two weeks ago it was weak cheated in the scrums, last week it was blocking and now he is saying this. is really disappointing because what he is implying is we are intentionally going out to injure somebody, that's not the case and we have never been like that and as a new zealander i would expect him to know that in the new zealand side it is not about intentionally hurting anybody, it is about playing hard and fair. galland said he would speak to dhahmaan to the referee about it before the second test but before that the lions face the para canes here, the starting 15 have been announced, jack nowell and george north and jonathan joseph will start. those players are among those looking to play their way into the testing. gatlin said there are opportunities still to be grabbed. it wasn't exactly a secret but crystal palace officially announced frank de boer

as their new manager earlier. the former netherlands captain replaces sam allardyce who left selhurst park at the end of last season. de boer has previously coached ajax and inter milan. and has been outlining his thoughts on his new role. to play in the premier league, it's a club that still can grow further and further. because every english clu b and further. because every english club in the premier league can spend a lot of money so they have the possibility to do something well with that money. i think there is a lot of prospective for this club to bea lot of prospective for this club to be a solid premier league club, and this is the most important thing right now. first of all, i didn't meet the players, so first of all i have to see them, of course. i have

my ideas and maybe one or two signings that i think is necessary. but first of all i want to see all of the players who are here right 110w. nathaniel chalobah and nathan redmond will both face fitness tests in the morning before a decision will be made on their participation for england's u21s in their semifinal against germany at the european championship in poland. tomorrow afternoon's game is england's first semi in the tournament since 2009. in a moment the thoughts of our football correspondent ian dennis but first here's england manager aidy boothroyd evoking memories of euro 96. obviously it wasn't the ending that we wanted, but i think a lot of people of that generation have a real affinity with england— germany games. they are always big games and exciting games. both teams have got good players. i hope that the build—up to the... the game is as

good as the build—up. new zealand have won this year's america's cup with a 7—1win over oracle tream usa. it was a dominant display from the kiwis who erased memories of four years ago when their 8—1 lead became a painful 9—8 defeat to the americans. tony husband reports from bermuda. the celebrations are well under way here in bermuda for kiwi fans and sailors. this has been a dominant display in the world's oldest international sporting trophy and the kiwis will be celebrating long into the night. the final result never really in doubt, they won 7—1, they won eight in all since the series began. the secret behind it, perhaps the technology they had in the boat in the shed behind us. they managed to produce foils that were a little different, they were radical in those designs and they certainly proved to be the quickest out on the water. it's also redemption for

them, four years ago in san francisco they were beaten in heartbreaking style by the same oracle heartbreaking style by the same ora cle tea m heartbreaking style by the same oracle team they have just defeated so oracle team they have just defeated so comprehensively. they are already talking about the next america's cup, the 36th edition likely to go to auckland. there will be a lot more celebrating before that happens. tony husband, bbc news, bermuda. very good indeed from them. that's all from sportsday. thank you forjoining us. coming up in a moment, the papers. hello and welcome to our look ahead to what the the papers will be bringing us tomorrow. with me are rosamund urwin, columnist at the evening standard and dan bilefsky, staff writer at the new york times. welcome both of you. we will talk to

them ina welcome both of you. we will talk to them in a moment after we bring you up—to—date with the front pages for tomorrow morning. these are the first editions. ‘thanks a billion' is the headline on the front page of the i — referring to the conservative—dup deal with northern ireland getting an extra £1 billion. the price of support for the minority government. the telegraph says the agreement may come at an even greater cost with the dup possibly coming back for more. the mirror splashes with the deal and shows a picture of theresa may and arlene foster shaking hands outside downing street. the metro says the three million eu citizens living in the uk will be required to apply for id documents to stay after brexit. one of the stories in the guardian is the us supreme court's decision to partially allow donald trump's travel ban on six mainly muslim countries to take place. the daily express reports an operation, using a plastic liner in the gut, could cure type two diabetes.

and the times shows a picture of hms queen elizabeth, britain's new £3 billion aircraft carrier, which passed through the river forth before starting trials in the north sea. let's get straight down to it and let's begin, i think, with the dup deal, the front page in most of the papers. yes. photos, which, it's almost as if theresa may's shaking hands with arlene foster and arlene foster is the dominant character in the picture on the front of the i. it does but theresa may didn't sign the document herself, she didn't lower herself to that. this is what the dup is good at. they radically underestimated them, they thought, well, they have ten mps. a pushover. yes. on the friday after it turned out we had a hung parliament they

thought they would get the deal quickly. i was writing about it at the time and everything was frantically changing and it has been 18 days now. this is what the dup has done for many years. they are good at letting negotiations go down to the wire because they know that squeezes out more of what they want. and actually they have an awful lot of what they want. the headline is
