    Starting the day on an egg could keep your blood pressure under control, research suggests. Scientists have shown that eggs produce proteins with a function similar to that of powerful blood pressure-lowering drugs.

    The research, from the University of Alberta in Canada, showed that when eggs come in contact with stomach enzymes (酶) they produce a protein that acts in the same way as Ace inhibitors, but more work is needed to show the effects outside a lab and in the human body.

    Earlier this month, British researchers declared that, contrary to popular beliefs, it is healthy to go to work on an egg. They concluded that the type of cholesterol (胆固醇) found in eggs has little effect on increasing heart disease risks.

    Researcher Professor Bruce Griffin, from the University of Surrey, said, "The wrong beliefs linking egg eating to high blood cholesterol and heart disease must be corrected. The amount of fat in our diet has an effect on blood cholesterol that is several times greater than the relatively small amounts of cholesterol found in eggs. The UK public do not need to be limiting the number of eggs they eat. They can be encouraged to include them in a healthy diet as they are one of nature's most nutritious foods."

    The British Heart Foundation dropped its three-egg-a-week limit in 2005. However, almost half of Britons believe the limit still applies.

    First-time shoppers at Seattle-based Amazon Go may feel as though they were stealing. That's because the 1,800 square-foot grocery store, which opened its doors to the public on January 22, has no cashiers or even checkout counters. Instead, as the name indicates, customers merely grab what they need and go! But before you start celebrating, the goods are not free—the cost of the purchase(s) is/are calculated electronically using “Just Walk Out” technology.

    The process is simple. Upon entering the store, shoppers “sign-in” by scanning their smartphones. Every item selected gets added to the bill automatically. If the customer changes his mind, all he has to do is return the purchase to the shelf, and it will be removed from the final bill. Though consumers will not find everything they need, they will be able to buy basics like bread, milk, and drinks. There are also numerous ready-to-eat breakfast, lunch, and dinner choices made by chefs in the on-site kitchen. Those that prefer to cook at home can select from the wide variety of Amazon Meal Packages.

    Once the customer exits the store, the system processes the purchases and charges the cost to their Amazon account. Within seconds, the customer is notified of the deal with a digital receipt that lists each item bought, as well as the time spent in the store. The accurate tracking is possible thanks to multiple smart cameras that monitor everything the shopper is doing. Kumar explains,“Cameras figure out which interactions(互动) you have with the shelves. Computer vision figures out which items are taken. Machine-learning also determines which item it is.” The company insists that the system is so accurate that shoplifting(偷盗) is impossible. And they should know, considering that Amazon employees have been shopping there since 2015!

    The store has raised some concern about the jobs of the over 3.5 million cashiers in America. However, Amazon officials say they have nothing to worry about because human employees are not being displaced. They are simply assigned other essential tasks, like preparing meals, restocking shelves, assisting customers, and solving technical issues.

Urban Transportation in Canada

    Public transportation & Transit passes

    All cities and most major towns in Canada have a public transportation system with one or more modes of transportation (bus, subway, train, etc.). The bus is the most common form of urban transportation in Canada. To use public transportation, you must purchase a ticket or a transit pass. Transit passes allow you unlimited use of public transportation for a specific period (one month or more). They are usually cheaper than buying many tickets if you plan to use public transportation often.

    Transportation for people with disabilities

    Public transportation often has features to assist people with disabilities. In many cities and towns, there are also transportation services available specifically for people with limited mobility, such as specially equipped buses. You can find out about these services in the same way you would learn more about other public transportation options.

    Etiquette on public transportation

When taking public transportation such as a bus or train, it is important to understand the unspoken rules of conduct in the shared space. Here are a few things to note:

    Be polite and respectful to others around you. For example, maintain an appropriate noise level when talking or making a phone call.

    If you are carrying a backpack or a large shoulder bag in a crowded public transit vehicle, keep it close to you, preferably at your feet to avoid hitting people with it as you walk by.

    Avoid pushing or touching others in order to make more room for yourself. Sometimes public transit can become very crowded, but it is important to keep calm and give others appropriate personal space.

    Have your proof of payment accessible in case you are asked to show it.

    Liana nervously bit her nails while she waited for the exam to arrive. She looked around the room; hundreds of other law students sat in rows staring anxiously at the tables in front of them. Just as she began to take a deep breath to calm her anxiety, an exam booklet(册子) was placed in front of her. This was the moment she had been expecting ever since she began law school three years ago. She picked up her pencil, and opened to the first page of the bar exam, a test for all students wanting to become licensed lawyers.

    Liana never thought she would want to become a lawyer. Her parents were both artists. Law was something she had not been exposed to as a child. But art made for a tumultuous career—both of her parents had struggled to find jobs and worked round the clock when they were young. Even though they finally seemed successful and happy, Liana wanted something different.

    She was the anchor on her high school debate team, and consistently impressed her competitors with her analytical thinking. "Never argue with Ms. Lakes," her teachers would say. So she chose to major in law. In her mind, she pictured herself in a New York City courtroom(法庭) dressed in an expensive suit, with papers in her hand, waving at the jury(陪审团) in a speech on human rights.

    But now, with the bar exam sitting in front of her, she started to worry. "What if I don't pass? Did I study enough?" Her thoughts raced through her mind. On the first page were seven paragraphs detailing a law situation followed by a series of questions. Liana read through the paragraphs, and quickly scribbled down an explanation of the first question before moving onto the next question. The next few hours went like this as the clock ticked closer and closer to the lunch hour.

    At 12:00 p.m. sharp, a buzzer(蜂鸣器) sounded and everyone was told to put down their pencils and walked out for an hour-long lunch break. At lunch, Liana met her friend, Kevin.

    "How did it go?" she asked. "To be honest, I've no idea. I just kept writing." Kevin said. Liana laughed and said she felt the same way.

    After lunch, the two exchanged words of encouragement. They strolled back into the exam center a bit more refreshed. Liana finished the second half of the exam that day with a better feeling than what she started with in the morning.
