Starting the day on an egg could keep your blood pressure (血压) 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.

    Have you ever noticed that the more you have the more you want? Let's face it. Thinking our life is good enough doesn't come naturally to many people. When we have high expectations of everything in life we will run into disappointment. Only when we are aware that needs are different from desires can we live with satisfaction. Here are a few ideas to help you be happier with what you have and who you are.

    Focus on what you are thankful for. Most people want things to be better than they are, or when things are going well, we forget to appreciate what we have. Learn to reflect on how much better things are than they could be. Focus on what you are thankful for. Write down 5 things you are grateful for right now.

    When we hold onto regrets from decisions we have made, it can really poison our well-being. Many people regret something they can no longer change, which ends up holding them back from moving forward in a more positive manner. What happened in the past is done and gone, so work to stay present and be mindful of the current moment to find more joy and fulfillment.

    When we use other people as the measuring stick for our personal success and quality of life we are likely to be less satisfied. Social comparisons can provide useful information when we try to learn from others, but they also hold our perspective in a discontented position. Compare yourself less with others so you can be satisfied more.

    When you are focused on your big ambitions and future goals you might elide the daily pleasures that surround you. Learn to slow down and absorb the wonder and beauty around you. Stay present and focus on the task you're undertaking at the moment. Don't let the life pass you by because you're always on the go and distracted by ambition.

    Practice looking at life through the lens of contentment and it will become more natural.

    Researchers are trying to figure out exactly when and where a lizard got trapped in the sap(汁、液) of a tree. Over time, the tree sap turned into amber (琥珀), preserving the lizard's mains, which a man discovered and donated to the Miller Museum of geology at Queen's University. But the man didn't report the amber's age and where he got it.

    “The man who donated it died, unfortunately,” said Ellen Handyside, an undergraduate student at Queen's University. “We are really starting from scratch in determining its history Ellen Handyside is leading the research into the amber-surrounded lizard. She and her colleagues analyzed the chemical composition of the 4.7-inch -long piece of amber and learned some facts. “The amber wasn't actually artificial,” she told Live Science, “and we found that it did match up quite well to an amber sample.”

    The researchers analyzed the amber's carbon and hydrogen isotopes(同位素) and the results indicated that the amber was formed from the sap of a flowering tree. Moreover, the results suggested that the tree and the lizard, for that matter, lived in an area with a lot of rainfall and dated to the Neogene, a period that lasted from the end of the Paleogene Period 23.03 million years ago to the beginning of the present Quatemary Period. Next, the scientific team realized that the 2.7-inch-long lizard was likely a gecko(壁虎), according to a detailed, 3D, digital model of the animal's body that the researchers created through X-ray microscopy scans.

“We looked at the skull —the teeth are in place and the ear bones are there too. And we've even got some flesh, skin and its long toes,” Handyside said. “It's fantastic!” She said she hoped that they could figure out how the creature fit into the gecko family tree. “When you think of a gecko, you think of short and fat toes and sticky pads. That isn't what we're looking at, but it's more likely to live in trees. If it were a tree-living creature, then its death actually could make more sense,” Handyside said.

    If you have the opportunity to visit some places in New Zealand, then the list below is our recommendation.

    Fiordland National Park

    This park is part of the South Westland World Heritage Area and is New Zealand's largest national park and one of the largest in the world. The scenery in Fiordland is nothing short of extremely beautiful, with steep mountains, wild waterfalls, and abundant rain forests. Being able to come back and forth in its deep bay attracts most of the visitors.

    The area has some of the world's greatest walks including the world famous Milford Track, which was described as the finest walk in the world in the early twentieth century.

    Abel Tasman National Park

    Abel Tasman may be New Zealand's smallest national park, but the attractions are huge. Located in one of New Zealand's sunniest spots, the area also has the best beaches in the country.

    The popular Abel Tasman Walk is a great way to see this park. It takes 3-5 days to complete. Sea taxis are also available and can drop you off at any number of beaches within the park.

    Rotorua

    Accessible from New Zealand's biggest city, Auckland, Rotorua is famous for its volcanic activities. Rotorua is also famous for its plentiful lakes which are great for swimming and fishing. The surrounding area contains plenty of native bushes and some famous walks.

    Rotorua is also the best area in the country to experience and learn about Maori culture.

    Mt Cook National Park

    Mt Cook as well as the surrounding area is an alpine(高山的) park within the World Heritage listed in South Westland. The biggest peaks in all of Australasia are here. The park doesn't contain many trees or plants due to the altitude. Walks range from a two­hour walk to difficult tracks suitable for experienced mountaineers only.

    A helicopter or plane ride gives visitors excellent views of the mountains with the option of landing at the top of Tasman Glacier, a true permanent snow­covered alpine environment.

    The Eiffel Tower is very famous in France. It is visited by 7 million visitors a year. The Eiffel Tower was designed by Gustave Eiffel in the late 19th century. On Monday, March 31st, 2019, it turned 130.

    The look of the Eiffel Tower is greatly loved by people today, but things were different when the design was first shown to the public. Many French artists thought that the design was ugly. However, Eiffel did not change a thing. He believed that once it was completed, people in Paris and visitors around the world would love the tower. He was certainly right.

    The tower became popular with the public as soon as it opened on March 31st, 1889, two years after the construction began. Over 3,000 people came to look at this new tower and even made the effort to climb the 1,710 stairs to the top. The 984-foot-tall Chrysler Building in New York City beat it.

    Today, the tower houses a number of restaurants on its first and second levels. The third level has been turned into a vast platform (平台). From there visitors can see the entire city of Paris. While visitors are allowed to take the stairs to the first two levels, the platform can only be got to by taking the elevators.

    To ensure that the “Iron Lady” always looks good, the tower is cleaned and repainted every eight years. It's an effort that takes a team of 25 workers, an entire year. If you travel to Paris one day, don't miss it, the excellent achievement.

China's Tianwen 1 Mars probe (探测器) conducted its fourth orbital correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.

The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布) the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Tianwen I has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and I. I million km from Mars. Depending on the two planets' orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen I is seen in its first selfies in space on Oct. 1, 2020. The administration also published a black-and-white picture of Mars taken by Tianwen I, the first snapshot (抓拍的照片) from the Chinese craft.

Tianwen I, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

A successful landing would make China only the second nation to place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署) a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.
