According to EMTP and Stat Gear CEO Avi Goldstein, every driver should be taught how to get out of a car when it becomes submerged in water.

“Accidents and natural disasters often occur so quickly that it's essential for drivers to be prepared,” says Goldstein. “In this case, preparation is simply knowing what should be done before it happens.”

        Goldstein offers the following lifesaving tips:

1.Try to stay calm. The worst thing you can do is become overly agitated and      panicked.

2. Don't try to open the door. This will cause the car fill with water very quickly.

3. Unfasten your seat belt or cut it if it's jammed.

4. Help free anyone else in the car.

5. Use a window punch — preferably spring-loaded. It's nearly impossible to break a car window with your hands or feet.

6. Exit through the broken window and swim up to safety.

      “Every car should be equipped with a window punch and seat belt cutter, but they are usually completely forgotten by car owners,” says Goldstein. For example, the T3 Tactical Auto Rescue Tool from Stat Gear features a 440c stainless steel serrated knife, seat belt cutter, spring-loaded window punch and LED light.

       Goldstein asserts that the T3 or another similar tool should always be within arms length of a driver. “If for any reason a driver becomes pinned into his or her seat, emergency tools need to be within reach--otherwise they are useless. They will do you no good in your trunk or backseat.” The following is a quick demonstration on how to escape a sinking car with a baby on board.

A few months after we moved to a small city in France, I wanted to meet my husband for lunch at the university where he worked. I got lost. I had to call him for help. One of his friends said to him later, "How could she get lost? She just needed to go straight."

Well, no. That's the problem. You never "just go straight", because France is the land of roundabouts (弯道). Highways, major streets, little village lanes – if you go straight long enough, you'll end up going in circles.

    Even after a year here, I'd still get lost going to the grocery store, or just about anywhere that wasn't within a hundred yards of my house.

I admit I have a horrible sense of direction, can't read a map, and am not such a good driver. Plus, I've been spoiled (宠坏) by living in American cities, where you just indeed need to "go straight". But in France, driving became my nightmare — the roads are roundabouts within roundabouts.

    Finally I found a solution: a GPS program on my smart phone. I rely on it to get anywhere, even places I've been.

    But it does leave me feeling very bad and helpless when, often, the program doesn't work, can't find a GPS signal, or gives wrong information. I'd have to wait until my GPS gets recovered, or else I use my old solution: I call my husband. Is the GPS making us more stupid, or helping us going around more? In my case, it's probably both.

    A Chinese scientist's attempt to produce the world's first gene-edited babies who are immune to HIV has caused floods concern.

    In an online video posted on Monday, He Jiankui, a biological researcher, announced that a pair of twin baby girls, Lulu and Nana, was born healthy a few weeks ago with genetic editing technology that can prevent them from being infected with HIV.

    He, who was believed to be in Hong Kong on Monday to attend the Second International Summit on Human Genome Editing, could not be reached for comment. But his announcement sparked a heated argument concarning medical ethics（伦理）and effectiveness.

    The Shenzhen Health and Family Planning Commission said on Monday evening that it had not received any ethical assessment application for the study, which is required as a prior condition for such experiments.

    More than 120 scholars from universities and institutes with high status from China and abroad,such as Tsinghua University and the Massachusetts Institute of Technology (MIT),strongly condemned the research in a signed statement, saying the “research” lacks effective ethics inspection, and it amounts to human experimentation,which is “crazy”.

    In the statement, published on Sina Weibo, the scientists said any attempt to make changes to human embryos with genetic editing and give birth to such babies involves high risk as an inevitable part, due to inaccuracies in existing genetic editing technologies.

    “Scientists all over the world dare not make such attempts due to the huge risks and more importantly, ethics. The government must make quick legal moves to strictly supervise（监督）such research. The Pandora's Box has been opened, and we may still have a chance of closing it before it is too late,”the statement said.

    Tsui Lap-chee, president of the Academy of Sciences of Hong Kong, said a lot of issues may occur in gene editing. If one gene is edited, it will affect others that interact with it. And the whole genome, a collection of genes, may also be affected.

    In the kitchen of my mother's houses there has always been a wooden stand (木架)with a small notepad(记事本)and a hole for a pencil.

    I'm looking for paper on which to note down the name of a book I am recommending to my mother. Over forty years since my earliest memories of the kitchen pad and pencil, five houses later, the current paper and pencil look the same as they always did. Surely it can't be the same pencil. The pad is more modern, but the wooden stand is definitely the original one.

    "I'm just amazed you still have the same stand for holding the pad and pencil after all these year." I say to her, walking back into the living-room with a sheet of paper and the pencil. "You still use a pencil. Can't you afford a pen?"

    My mother replies a little sharply. "It works perfectly well. I've always kept the stand in the kitchen. I never knew when I might want to note down an idea, and I was always in the kitchen in those days."

    Immediately I can picture her, hair wild, blue housecoat covered in flour, a wooden spoon in one hand, the pencil in the other, her mouth moving silently. My mother smiles and says, "One day I was cooking and watching baby Pauline, and I had a brilliant thought, but the stand was empty. One of the children must have taken the paper. So I just picked up the breadboard and wrote it all down on the back. It turned out to be a real breakthrough for solving the mathematical problem I was working on."

    This story—which happened before I was born—reminds me how extraordinary my mother was, and is, as a gifted mathematician. I feel embarrassed that I complain about not having enough child-free time to work. Later, when my mother is in the bathroom, I go into her kitchen and turn over the breadboards. Sure enough, on the back of the smallest one, are some penciled marks I recognize as mathematics. Those symbols have traveled unaffected through fifty years, rooted in the soil of a cheap wooden breadboard, invisible(看不到的)exhibits at every meal.

    In the ongoing battle between Tiger Moms, French Mamas, and everyone else who wants to know what is the best way to raise their kids, a new study adds evidence that the extreme Tiger-style may do more harm than good. Authoritarian parents are more likely to end up with disrespectful children with violent behaviors, the study found, compared to parents who listen to their kids with the goal of gaining trust.

    It was the first study to look at how parenting styles affect the way teens view their parents and, in turn, how they behave. The study considered three general styles of parenting. Authoritative parents are demanding and controlling while also being warm and sensitive to their children's needs. Authoritarian parents, on the contrary, are demanding and controlling without the appearance of caring, attachment and receptiveness. They take a "my way or the highway" approach to their kids. Permissive parents, the third group, have warm and receptive qualities, but they set few boundaries and carry out few rules.

    Using data on early 600 kids from an ongoing study of middle school and high school students in New Hampshire, researchers from the University of New Hampshire were able to find "my way or the highway" parenting with more violent behaviors like robbery, drug-taking, and attacking someone else with the intention of hurting or killing. Firm but loving parenting, on the other hand, led to fewer lawbreakers. Permissive parenting, surprisingly, didn't seem to make much of a difference either.

    To explain the link between parenting style and behavior in kids, the researchers suggested that what matters most is how reasonable kids think their parents' power is. This sense comes when kids trust that their parents are making the best decisions for them and believe that they need to do what their parents say even if they don't always like how their parents are treating them. When kids respect the power of their parents, the researchers reported in the journal of Adolescence, their behavior is better. Previous research has also linked firm but caring parenting with kids who have more self-control and independence.

    "When children consider their parents to be the reliable figure, they trust the parents and feel that they have a duty to do what their parents tell them to do," said lead researcher Pick Trinkner. "This is very important as the parent doesn't have to rely on a system of rewards and punishments to control behavior and the child is more likely to follow the rules when the parent is not physically present."
