Do you wake up every day feeling too tired, or even upset If so, then a new alarm clock could be just for you. The clock, called SleepSmart, measures your sleep cycle, and waits【C1】______you to be in your lightest phase of sleep【C2】______ rousing you. Its makers say that should 【C3】______you wake up feeling refreshed every morning. As you sleep you pass【C4】______ a sequence of sleep states—light sleep, deep sleep and REM (rapid eye movement) sleep—that 【C5】______ approximately every 90 minutes. The point in that cycle at which you wake can【C6】______how you feel later, and may【C7】______ have a greater impact than how much or little you have slept. Being roused during a light phase 【C8】______you are more likely to wake up energetic. SleepSmart 【C9】______ the distinct pattern of brain waves 【C10】______during each phase of sleep, via a headband equipped 【C11】______ electrodes and a microprocessor. This measures the electrical activity of the wearer" s brain, in much the【C12】______way as some machines used for medical and research【C13】______ , and communicates wirelessly with a clock unit near the bed. You【C14】______the clock with the latest time at 【C15】______you want to be wakened, and it 【C16】______duly wakes you during the last light sleep phase before that. The 【C17】______was invented by a group of students at Brown University in Rhode Island 【C18】______ a friend complained of waking up tired and performing poorly on a test."【C19】______sleep-deprived people ourselves, we started thinking of【C20】______to do about it," says Eric Shashoua, a recent college graduate and now chief executive officer of Axon Sleep Research Laboratories, a company created by the students to develop their idea. 【C17】

Google already has a window into our souls through our Internet searches and it now has insight into our ailing bodies too. The Internet giant is using its vast database of individual search terms to【C1】______ the emergence of flu up to two weeks 【C2】______government epidemiologists. Google Flu Trends uses the【C3】______of people to seek online help for their health problems. By tracking【C4】______for terms such as "cough", "fever" and "aches and pains", it claims to be able to【C5】______estimate where flu is【C6】______. Google tested the idea in nine regions of the US and found it could accurately predict flu【C7】______between 7 and 14 days earlier than the federal centres for disease control and prevention. Google hopes the idea could also be used to help【C8】______other diseases. Flu Trends is limited【C9】______ the US. Jeremy Ginsberg and Matt Mohebb, two software engineers 【C10】______in the project, said that【C11】______in Google search queries can be very 【C12】______. In a blog post on the project they wrote: "It turns【C13】______that traditional flu surveillance systems take 1 to 2 weeks to collect and【C14】______surveillance data but Google search queries can be【C15】______counted very quickly. By making our estimates【C16】______each day, Flu Trends may provide an early-warning system for outbreaks of influenza." They explained that 【C17】______ information health would be kept【C18】______. "Flu Trends can never be used to identify individual users【C19】______we rely on anonymised, aggregated counts of how often certain search queries【C20】______ each week." 【C18】
