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.

    The human brain remembers negative experiences more easily than positive ones. Our brains have developed this way because threats, like dangerous animals, had a more immediate effect on our ancestors' survival compared to positive things like food or shelter. As a result, you likely know what makes you unhappy, but do you know what makes you happy?

    Research suggests that our level of happiness depends partly on factors we cannot control—our genes and our life circumstances. But our level of happiness is also shaped by the choices we make. If you've been chasing wealth, fame, good looks, material things and power, you may be looking for happiness in all the wrong places. Psychologists suggest that the following habits make people happier.

    People who form close relationships tend to be happier than those who do not. The number of friends we have is not important. What matters is the quality of our relationships. Relationships that bring happiness usually involve the sharing of feelings, mutual respect, acceptance, trust and fun.

    People who exercise regularly improve both their physical and mental well being. Some research has shown that exercise can be as effective as medication in treating depression.

    When we are so interested in an activity we enjoy that we lose track of time, we are in a state of flow. The activity could be making art, playing piano, surfing, or playing a game. People who experience flow in their work or hobbies tend to be happier.

    People are more likely to be happy if they know what their strengths are and use them regularly, People who set goals and use their strengths to achieve them tend to be happier. People are especially happy when they can use their strengths to serve the greater good.

    People who think positively by being grateful, mindful and optimistic are more likely to be happy. Being grateful means being thankful, Bejing mindful means being open to, focusing on and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

    We arrived at the hospital to find Dad was very weak, but his smile was as sure as ever. It was another attack of pneumonia (肺炎). My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from the hospital and look after him. But I longed to be able to let him know that we cared too, even when we weren't with him.

    Then I remembered a family tradition when our children were small. When leaving their grandparents' home after a visit, each child would write a love note to their grandparents. They hid notes in the cereal (麦片) box, under a hairbrush, next to the phone or even in the microwave oven (微波炉). For days, their grandparents would smile as they discovered these signs of our love.

    So as I tidied Dad's kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, “Dad, I put the food in the fridge so it wouldn't spoil.” Some expressed my love, “Dad, I hope you will sleep well in your new bed.” Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, “Dad, if you have found this note, you must be feeling better. We are so glad!”

    Just like his medicines strengthened him physically, these “emotional vitamins” would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, “Pretty good. I just found your note under my pillow upstairs!”

German cities are redrawing road markings to create new cycle paths for the duration of the Covid-19 lockdown, as cyclists demand more space to physically distance on their way to work.

Local authorities in the Kreuzberg district of Berlin trialled (试行) temporary widening of two cycle paths on 27 March, arguing it would help cyclists keep the required 1.5-metre distance apart while car traffic was down owing to Germans' coronavirus (冠状病毒) restrictions.

On Friday, the council declared the plan a success because it had improved cycling safety while not blocking traffic.

The council said it had used removable tape and mobile signs to mark out the widened paths, which can be removed when the current restrictions on movement are lifted.

Residents in 133 other German cities have formally submitted applications for similar pop-up bike paths to their local authorities on the back of a campaign by Environmental Action Germany (DUH), an environmental NGO.

The campaign group cites new research linking air pollution to higher coronavirus death rates as an argument for redrawing road signs across the country. "The coronavirus is showing us that clean air is necessary," said DUH's chair, Jurgen Resch. "It is now especially important to temporarily make it more important for people to move safely on their bikes. This will help improve air quality, enable exercise in fresh air while keeping a safe distance and avoid unnecessary accidents."

In Germany, bike repair shops are allowed to work because of the Covid-19 going on. Three federal states, Berlin, Saxony-Anhalt and Mecklenburg-Vorpommern, have allowed bike shops to stay open.

After a decade of negotiations, nearly 200 countries have agreed to a new United Nations treaty（条约）to protect the world's oceans, the first of its kind in 40 years. The High Seas Treaty aims to protect 30% of the open oceans by 2030, setting a plan in motion to preserve this vast area.

Oceans cover about 71% of the Earth's surface and are home to countless species of animals and plants. They play a crucial role in maintaining a healthy planet. However, overfishing and pollution from ships and other sources have severely impinged on many marine （海洋的）species and ecosystems.

The last major UN sea treaty in 1982 described the "high seas"—the parts of the oceans that aren't controlled by any country—but it did not protect them. The high seas, which account for two-thirds of the ocean, currently have only 1. 2% of their massive area protected. A marine protected area（MPA）is an area in the sea with strict rules about fishing and other activities. While more and more countries have established MPAs in their waters, most are not connected, limiting their effectiveness for migratory（迁徙的）species.

Last December, over 110 countries committed to protecting 30% of their land and ocean areas by 2030. The High Seas Treaty now enables the extension of this goal to the entire ocean. It aims to make 30% of the high seas become protected areas by 2030 and requires that proposed activities on the high seas undergo assessment for their potential impact on the ocean environment.

Reaching the agreement was challenging due to differing views on ocean protection among countries, such as limits on fishing or pollution. Disagreements also arose over sharing resources between rich and poor nations, with the latter seeking an assurance that resources benefit everyone, not just those in wealthy countries.

The treaty is not yet final and must be officially accepted at a UN meeting. Then it must be approved and signed by enough countries before it takes effect.
