The vast majority of fitness trackers count your steps and are worn around the wrist, but now there's a device that's designed to be worn like a necklace and monitors tiny movements to improve your posture. The Fineck device aims to address neck pain by tracking tiny movement, spotting bad habits and suggesting exercises via an accompanying app. Made from silicone and titanium , Fineck monitors a wearer's movement, balance, posture and movement thanks to sensors inside. The Mountain View California-based firm says that a high percentage of people suffer from neck pain and associated problems, probably caused by more individuals doing office jobs, which generally involve leaning over computer keyboard. The device contains sensors, several different types of instruments to monitor movement, plus a monitor to shake. It connects to an IOS app via Bluetooth so that wearers can see their bad habits and play "neck training" games. The app warns of health risks and records a user's activity to build up a customer personal health description. The necklace shakes to give smart advice, such as reminding wearers to sit up straight. The app also allows users to set goals, like many other wearables do. "Fineck is the first wearable device for your neck that tracks your neck activity and warn you when you are in a bad posture for too long. You can also exercise your neck with Fineck's interactive games." The company writes on Kickstarter. "No matter where you are and what you are doing at office, on the go, or simply just feeling bored, Fineck will bring you enriched exercise experience through motion sensing games and therapies." It also claims that it is "the world's first titanium wearable device". The metal is widely used in fashion stuff that you can wear or carry to match your clothes because it is lightweight, durable and does not tend to cause allergic reactions. It also offers additional features such as shaking to indicate alerts on a user's smartphone, but it is not currently clear whether it can also be used... We can infer from the passage that the Fineck device will _ . A) actually not cause allergic reactions. B) enrich your life by providing "neck training" games C) monitor a wearer's movement due to the material it is made of D) help to correct your improper postures

How can you tell if someone's lying? The answer is, they're probably not. Traditional economics says that people are rational beings who will lie if it's to their advantage. A recent university study has shown that, actually, we're pretty honest --especially when we're at home. Researchers in Germany phoned people at home and asked them to toss a coin. There was a strong financial incentive to fake the result: if the coin landed tails-up, the participants would receive money or a gift ticket, while if the coin landed heads-up, they would get nothing. Because they were on the phone, they knew there was no risk of getting caught if they lied. And yet people told the truth.Over hundreds of tosses, a coin will land tails-up roughly 50% of the time. In this study 0ver half the people asked (55.6%) said that the coin landed heads-up, which meant they would receive nothing. Previous studies had found that people were more dishonest. In those laboratory studies, 75% of people reported a winning coin and claimed a reward. So the research team thinks it's being in our own homes which makes us play fair, although it's not yet clear why. In fact both types of study show people are surprisingly reliable. Even in the laboratory, 25% of people turned down a reward by telling the truth. The researchers say this is because honesty is highly valued in human society.We care about our reputation and our sense of ourselves as respectable people. So lying has a psychological cost and it seems this cost is more important than the financialbenefits of lying . Which of the following is TRUE according to the research? A) There was no risk of getting caught lying if people were on the phone. B) The participant would receive nothing if he said the coin landed tails-up. C) The studies could help to correct the mistakes of the participants D) people would play fair and behave acceptably if invited to the laboratory.

Each year, about 10,000 to 100,000 animal species die off. They join the countless species that have gone extinct over the course of Earth's history - and extinction means forever. At least it used to. Scientists are now closing in on the ability to bring back extinct species. No, this doesn't mean the plot of Jurassic Park is going to become a reality. Researchers need DNA to bring back a species. DNA is the chemical that carries the structure for a living thing. Dinosaurs have been gone too long for any of their DNA to remain in fossils. But there's a very real chance that we will be able to bring back more recently extinct species. This could even include Ice Age animals like the woolly mammoth. In 2003, a team of Spanish and French scientists re-created the Pyrenean ibex, which had gone extinct three years earlier. The new animal didn't survive long, but scientific advances should improve the success rate. In January, Australian scientists announced that they were on their way to bringing back the gastric brooding frog. That we can bring species back doesn't mean that we should. There may be benefits to reviving a species. But there's no way to know how it will turn out. For example, would a passenger pigeon fit into its old habitat? Or might it crowd out existing species? Environmentalists worry that our ability to bring species back might cut down support for the hard work of traditional conservation. Why worry about preserving a wildlife habitat or fighting poachers if we know we can just make up for our mistakes? But those extinctions are our mistakes to correct, which may give us an obligation to do so. As businessman and environmentalist Stewart Brand recently said, "Humans have made a huge hole in nature. We have the ability now to repair some of that damage." We would do well to remember the lesson of Jurassic Park: Proceed with caution. Why is the plot of Jurassic Park not going to become a reality? A) Because dinosaurs are forbidden to be brought back to life. B) Because it is impossible for scientists to bring back extinct huge animals. C) Because scientists are not interested in bringing back dinosaurs. D) Because it is impossible to find DNA of dinosaurs in fossils.
