When it comes to the Internet, people talk about the password most. Actually, it's been under fire for a long time. Research has shown that passwords are not a very good way to protect sensitive information.

    People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the longer and more complex passwords become, the more people are likely to forger them. Therefore, they use the same password for every service or application. These are all big no-noes and essentially defeat the purpose of a password.

    Google is trying to kill off passwords on Android devices by introducing the Trust API, which does what simple passwords cannot and gives developers a framework for securing their application using a number of security systems and metrics(衡量标准)on the device. A Trust Score will be generated based on a number of metrics including your device location, face scanning, fingerprints, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not secure. But taken together, these metrics will help recognize the real “you”.

    The good news is that Google has already been testing this on real world data. Google has proven the Trust API works. Next Google will run tests will some banks to see if the Trust API meets their needs before rolling out the system on Android phones later. It may take another year for apps and popular sites to start using the Trust API.

    This is a pretty exciting change. Passwords have been around for a lone time. Although the security of systems has been improved, the usability of systems hasn't been proved much. Google appears to have the best of them. Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

    It's a popular belief that a fish's memory lasts for only seven seconds. It may seem sad to think that they don't remember what they've eaten or where they've been, and they don't recognize you or any of their friends — every moment in their life would be like seeing the world for the first time.

    But don't be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago.

    In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again.

    Researchers used computer software to monitor the fish's movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.

    In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively（挑衅地） in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.

    Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild.

    “If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.

    For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

    We get it: You're tired. You're busy. And your shoes are away over there. Excuses are OK sometimes, but not every day—and especially not today. So put on your sneakers, get up off the couch, and let us kick your excuses to the curb (路边).

    “I…dislike…panting !”

    Being really out of breath may mean you're trying too much too soon, which will kill your confidence. But you don't have to be huffing and puffing to get a workout. Being active doesn't have to mean high-intensity. It's just about moving.

    “I hate exercise.”

    It may seem unbearable, but you just have to get started. Exercise releases endorphins (your brain's own feel-good chemicals), which can be habit-forming. What' s the best exercise? The one you'll do regularly. So you may hate running. Don't run! Ride your bike or just dance. Even cleaning your room is active. As long as you're moving and getting your blood pumping, it counts. So get creative.

    “I don't have time.”

    You may not have lots of time to spare when you're busy with schoolwork, but we bet you can find 10 minutes. Bonus: An activity break will send oxygen to your brain, making you super-alert and more creative too. Famous thinkers like Aristotle and Steve Jobs liked “walking meetings," and you can follow in their footsteps by moving around while you brainstorm about a tough task or memorize your English vocabulary.

    “I never see results!”

    Even if you train with the help of a professional, you won't see results right away. But you will feel them almost immediately. Don't focus on how your body looks—focus on how you feel. Keep a journal of when you exercise (or don't) and how you feel that day: Stressed? Focused? Tired? When you start noticing the amazing effects of exercise, you'll have no excuses.

    These days I am on my very best behavior whenever I leave the house. If I am wearing pantyhose(连裤袜), I double-check to ensure there is no hole on it. I drive thoughtfully as if I'm being tested for a license. I won't even allow myself to frown when another driver is blocking my path.

    My kids have noticed my fear in public. "Why are you looking all around, Mum?" they asked.

    "You can't be too careful," I said. "Every single person around us is hiding one of cell phone cameras. They are glad to catch somebody doing something stupid or embarrassing. Then they'll put it on YouTube and a million people will see. I'm not taking any chances."

    "But I don't think anyone is interested in filming you putting on your lipstick for a YouTube video." answered one kid.

    "Oh, really? Don't count me out so quickly." I said.

    Actually, in some cases, I am all for public shaming. For example, I admire the cleverness of the man who put up a website where he posts photos of cars and license numbers of people who occupy two parking spots. And I take secret pleasure in photos of politicians with their fingers in their noses. Throwing light on bad behavior can awake the sleepy conscience(良知).

    But what about the poor guy who has already had a bad day at work and then loses his temper at a rude store clerk? What about the woman whose only crime is a terrible judgment error at the hairdresser? Do they deserve to have their images uploaded onto the Internet for all the world to see?

    None of this is new, of course. Allen Funt pioneered the art of catching people during unguarded moments back in the 1940s with "Candid Camera". But there's a difference. On "Candid Camera", people are set up in staged situations, such as riding in an elevator that goes sideways. And they must give permission before they enjoy their fifteen minutes of fame. Now we are a nation of Allen Funts. This can't be a good thing.

New research from the University of Portsmouth has shown a marked increase in shipping in the North East Atlantic. Scientists now warn that more monitoring is required to help protect sea life. 

Researchers at the University of Ponsmouth have discovered that rates (率)of shipping in the North East Atlantic area rose by 34 per cent in a five-year period. The research is the first detailed survey of shipping activity in the North East Atlantic. Researchers used data from over 530 million vessel(船)positions recorded by Automatic Identification System(AIS). They looked at the change in shipping between 2013 and 2017 across ten different vessel types. In total the study area covered 1.1 million km², including waters off Belgium, Denmark, France, Germany,Iceland, Ireland, The Netherlands, Norway, Portugal. Spain, and the UK. 

Lead author, James Robbins said:"This change is likely to put more pressure on the marine(海 洋的)environment, and may influence the protection of at-risk species. Renewed monitoring effort is needed to make sure that protective measures are enough to save species under threat in a changing environment. "

Some of the greatest shipping increases were found in areas close to the Spanish coast. The Espacio Marino de la Costa da Morte saw a rise of 413 percent in vessel activity. It is an area used to protect seabirds. 

Dr. Sarah Marley, Visiting Researcher at the University of Portsmouth, said:"Shipping is the most widespread human activity in our oceans, carrying a set of threats-from unnoticeable effects like underwater noise pollution to serious results when ships hit whales. "

Professor Alex Ford. from the University's Institute of Marine Sciences, said:"Given the well- documented effects that shipping can have on the marine environment, it is necessary that this situation continues to be monitored-particularly in areas used to protect vulnerable(脆弱的)species which may already be under pressure. "
