Studies show that you may be lied to every day anywhere from 10 to 200 times. We say, “Nice song.” “Honey, you don't look fat in that, no.” But another study showed that strangers lied three times within the first 10 minutes of meeting each other. We lie more to strangers than we lie to coworkers. Men lie eight times more about themselves than they do about other people. Women lie more to protect other people. If you're married, you're going to lie to your wife/ husband in one out of every 10 communications. If you're unmarried, that number drops to three. But look, if at some point you got lied to, it's because you agreed to get lied to. Truth about lying: lying's a cooperative act. Not all lies are harmful. Sometimes we're willing to get lied to for social dignity(尊严), maybe to keep a private secret.

    Lying is complex. It exists in our daily and business lives. We're deeply disturbed by the truth. We explain it, sometimes for very good reasons, other times just because we don't understand the gaps between ideals and realities in our lives. We're against lying, but secretly we're for it in ways that our society has practiced for centuries and centuries. It's as old as breathing. It's part of our culture and history. Think the stories from Dante, Shakespeare, the Bible, News of the World.

    Lying has great value to the evolution of human beings. Researchers have long known that the more intelligent the species, the more likely it is to lie. We humans like to become leaders. It starts really early. How early? Well, babies will pretend to cry, pause, wait to see who's coming and then go right back to crying. One-year-olds learn hiding truth. Five-year-olds lie outright and try to control through flattery (奉承). Nine-year-olds, masters of covering up.

    So what do we do about lies? Well, there are steps we can take to guide our way through the bushes. Trained lie spotters (检测员) get to the truth 90% of the time. The rest of us, we're only 54% right. There are clever liars and stupid liars, but there're no real creative liars. While lying, we all make the same mistakes, and we all use the same techniques.

    A mechanical bicycle lock, like a U-lock, should be attached to a solid and immobile object like a rack (架子) to ensure safety. However, these racks are quite rare and popular, thus often occupied and although a bicycle lock prevents the bike from being carried away, as it fixes single parts like the frame or the wheels, other parts can be dismounted. Therefore an electronic system, consisting of several sensors, can extend the range of protection with only few components and less effort.

    The ‘FID Bikealarm' is a motion sensitive electronic alarm system that is attached to the rails of a bike saddle (座椅). Featuring omnidirectional (全方位) movement sensing to detect tiny movements or speeding-up and a small whistle emitting >120dB alarm sound to scare off potential thieves by arousing attention.

    The internal microcontroller uses a complex computer program to distinguish between a serious theft and harmless shaking movement as it senses and adapts to the environment. The usage is quite simple: identify yourself by holding the RFID tag close to the case to lock or unlock the alarm system signaled by feedback sounds. The RFID-technology is predestined for achieving this simple and secure interaction because it doesn't require any complex system, interaction or other devices—just a small tag.

    The ‘RFID Bikcalarm' is meant to be a useful add-on to mechanical bicycle locks as it massively extends the range of protection with few components. It is low-cost, durable and easy to use. The internal battery can be charged by USB.

    Painkillers (止痛药) are turning out to be a real pain: according to a new study in the British Medical Journal. Taking them for just a week can increase your risk of heart attack by 50%. The research suggested that the risk related to the use of certain drugs was greatest with higher doses (服用量) and during the first month of use. The potential risk may increase by 75% for medicines like ibuprofen (布洛芬) and naproxen, and more than 100% for rofecoxib.

    It all sounds bad but, your risk is very low, — say, one in a million — a 100% increase means you still only have a two in a million chance. Of course, all painkilling medication that works can have side effects — nothing is safe and effective. Paracetamol (扑热息痛) has very few unless taken too much, in which case it can cause serious liver danger, but it isn't very effective. Drugs like opiates are strong painkillers but easy to be addicted and often have other bad effects. Maybe you find that you are in a dilemma now. But don't despair; you can refer to a pain clinic for some professional guidance. For ongoing pain, music and exercise may be the best choices to help you reduce the feeling of it.

    Scientist at Harvard have recently done a quite horrible study on mice. They made the mice experience extremes of hot and cold, applied pressure to their back legs and injected the capsaicin (辣椒素) into their feet. And then they timed how long it took them to respond to the pain. Lack of sleep increased the discomfort, while stimulants (兴奋剂) such as caffeine made them less responsive to pain. This has been widely reported that a good night's sleep and a cup of coffee in the morning may help reduce pain.

    But anyway  don't throw the pills away because the study also shows taking small doses of drugs, such as for short periods of time can be effective and safe as long as your heart is in good condition.

    Rivers are earthly arteries(要道) for the nutrients, deposits and freshwater that sustain healthy, diverse ecosystems. Their influence extends in multiple dimensions—not only along their length but below­ground to aquifers(蓄水层) and periodically into nearby floodplains.

    They also provide vital services for people by fertilizing agricultural land and feeding key fisheries and by acting as transportation corridors. But in efforts to ease ship passage, protect communities from flooding, and draw off water for drinking and irrigation, humans have increasingly constrained and broken these crucial water ways. “We try to control rivers as much as possible,” says Gunther Grill, a hydrologist at McGill University.

    In new research published in May in Nature, Grill and his colleagues analyzed the barriers to 12 million total kilometers of rivers around the world. The team developed an index(指数) that evaluates six aspects of connectivity—from physical fragmentation (by dams, for example) to flow regulation (by dams or levees) to water consumption—along a river's various dimension. Rivers whose indexes meet a certain threshold(临界值) for being largely able to follow their natural patterns were considered free­flowing.

    The researchers found that among rivers longer than 1,000 kilometers (which tend to be some of those most important to human activities), only 37 percent are not blocked along their entire lengths. Most of them are in areas with a minimal human presence, including the Amazon and Congo basins and the Arctic. On the contrary, most rivers shorter than 100 kilometers appeared to flow freely—but the data on them are less comprehensive, and some barriers might have been missed. Only 23 percent of the subset of the longest rivers that connect to the ocean are uninterrupted. For the rest, human infrastructure is starving estuaries(河口) and deltas (such as the Mississippi Delta) of key nutrients. The world's estimated 2.8 million dams are the main cause, controlling water flow and trapping deposits.

    The new research could be used to better understand how proposed dams, levees and other such projects might impact river connectivity, as well as where to remove these fixtures to best restore natural flow. It could also help inform our approach to rivers as the climate changes, says Anne Jefferson, a hydrologist at Kent State University, who was not involved in the work. Existing infrastructure, she says, “has essentially been built to a past climate that we are not in anymore and are increasingly moving away from.”

My grandfather was born in a small town in Italy. He would wake up at four in the morning every day to work on the farm. Although he was a great student in school, he only went up to Grade 3 because he was required to help with the family farm. 

Later, my grandfather used his own hard-earned savings—the small amount was all he had—to travel to Canada. He was alone in a new country, not knowing anyone and not speaking English or French. At a farm, the owner quickly saw what a hard-working young man my grandfather was, so he paid my grandfather a much higher salary. Although the owner was very nice to him and treated him like family, he was not satisfied. He dreamed of being more successful, of better career advancements. 

One day, he got an offer to work in the construction industry. My grandfather, a newly immigrated young famer, who was eager to move up in the world, caught this opportunity and prospered( 发达 ) through hard work. Around 1967, however, he become overwhelmed(不知所措的)with stress, sleepless nights and anxiety from the business. He also had two young daughters to take care of and my grandmother was in the hospital at the time. The combined stress and anxiety unfortunately drove him into a major depression. During a medical check-up, his doctor warned him about his health. He knew it was time for him to make a change and decided to sell his shares in the company. 

He then began a smaller business of his own, which resulted in less stress and more time with family. Had he chosen not to quit his former job, he might have been a billionaire today. My grandfather will turn 95 in October; even at this ripe old age, he is still strong, well and high-spirited. Looking at his story as a life example, he teaches us to work hard, but at the same time not to forget to enjoy life and have a good sense of humour about it all. 

Work is important, sure, but there is much more to life than just that. Overall, this is the ultimate key to happiness.
