“... which surround breast cancer are an example of these difficulties. The cause of the disease is unknown, although many factors, including geographical, reproductive and social influences, have been shown to produce a slight increase in risk. Attempts at early detection are still being evaluated, and it is not yet clear what benefit ‘screening’ will ...”

“... merely in office at the time. This is three lines less than Bonar Law, dubbed by Asquith as the unknown prime minister, which proportionately must make Russell practically unheard-of. Such are the revenges of history, or at least of historians. Not that Asquith comes off much better when his 12 lines are measured against Lloyd George’s 92, nor even ...”

“... The dormitory had been built in the 1980s. Cockroaches were everywhere, even lukewarm water was unknown and gas was available only at certain times. Katya came from a military family in Sevastopol. Her father, a retired navy officer, was living in Rostov on Don in order to get a Russian pension, which was much higher than the Ukrainian one. When I knew ...”

“... solely on feeling. But I was struck, leaving the courtroom for the final time, by how much remains unknown, unresolved.*The first half of the trial gave voice to the victims of the attacks; in the second half, the court looked more carefully at the accused. But the people whom one would most wish to hear from were absent. We can’t hear from Samy Amimour, who ...”

“... other than that he was a young black male. They made eye contact, and he ran, for reasons unknown. The officers arrested him and placed him face down. Unable to breathe, he asked for an inhaler, to no avail. The officers found a sliding knife on him, which is legal to carry, but charged him with possession of a switchblade, which isn’t. He was then ...”

“... of his depictions of women is particularly evident in the prints. One lithograph portrait of an unknown woman, breasts bared, navel impossibly high, is titled Woman with Red Hair and Green Eyes: Sin. Munch’s women loll around on beds with hangovers or try to entrap poor frightened men with their long red (danger!) hair. They seem to be ciphers for his own ...”

“... guard. Almost everyone was wearing a face-mask. I spent the night brooding about the proximity of unknown people and the poorly circulated air. Hypochondria is infectious, I thought. Over the following weekend – 26-27 April – things started to get odd. Each day began with thick fog, pushed unwillingly aside by a cold sun. Police cars circled the streets ...”

“... who first subjected him to a Jesuitical interview that takes place in another stage set – an unknown room, three chairs and a single bed, a cellphone and an alarm clock. There is a beseeching, earnest boy, an arrogant, dismissive woman, and a suitcase full of money, to be taken to Budapest for an arms deal. These stock situations might have something to ...”

“... at an early age and was compounded, during his brief attempt at postgraduate research, by ME, an unknown illness half a century ago. Kyle’s best known work is his history of Suez, published in 1991: he was in his late sixties, with a sterling career as a journalist and several fellowships behind him, by now a senior associate member of St Antony’s and ...”

“... conclusion was immediately criticised by other scientists, who complained that the Russians, for unknown reasons, had examined only four of the twenty bone samples they had received, choosing particularly those bones, like the skull, that polonium would be unlikely to penetrate. The Swiss team found levels of polonium that were 36 times higher than ...”

“... expedition was a triumph of surveying – they managed to chart hundreds of miles of previously unknown coastline – but their inexperience in polar travel and inadequate supplies meant that the journey back to civilisation, across the ‘Barren Ground’, turned into a catastrophe. Food ran out while they were still days from safety, and the men were ...”

“... from Miller’s office at night; in Miller’s discovery that Barbara Hellerman was killed by an unknown assailant in the New York subway. Violence against women is no longer a controlling device wielded by the thought police but something real. There are no redundant details in The Horned Man. A lot may remain unexplained, but it’s hard to find anything ...”

“... Washington Post at the end of June, Barton Gellman and Jo Becker revealed much that was previously unknown, if not entirely unsuspected, about the way Cheney operates. Gellman and Becker’s series was more concerned with Cheney’s methods than with his motives (Halliburton is mentioned only once), and this was surely the right emphasis: what politicians do ...”

“... is anachronistic when applied to societies where such emphasis on individuality was unknown. There is no evidence of professional arbitration in England as there is in contemporary Ireland, where the brithem was a legal expert who regularly heard disputes. Nor is there any sign of the bonus homo, the single private arbitrator of Roman ...”

No wonder he sought out stasis. The hands of the young dancers were adapted to a precise and disciplined school of movement over long years of training. Wrist, palm, thumb and fingers ...”
