    LONDON-A British judge on Thursday sentenced a businessman who sold fake(假冒的) bomb detectors（探测器） to 10 years in prison, saying the man hadn't cared about potentially deadly consequences.

    It is believed that James McCormick got about $77.8 million from the sales of his detectors-which were based on a kind of golf ball finder--to countries including Iraq, Belgium and Saudi Arabia.

    McCormick, 57, was convicted(判罪) of cheats last month and sentenced Thursday at the Old Bailey court in London.

    “Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people,” Judge Richard Hone told McCormick. “you have neither regret, nor shame, nor any sense of guilt.”

    The detectors, sold for up to $42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they “lacked any grounding in science” and were of no use.

    McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand.

    “I never had any bad results from customers,” he said

    If you have a long holiday to spend, where can you go?

Nikoi Island, Indonesia

    Less than 85 km – but somehow a whole world away – from Singapore's shining skyline lies Nikoi Island. Surrounded by white sandy shorelines and vivid coral reefs, Nikoi's centre is hidden in rainforest, resulting in amazing biodiversity seen in its native plants, animals and bird life. Marrying traditional Indonesian craftsmanship with contemporary design, Nikoi boasts just 15 stilted（建于支柱上的）beach houses, all with breathtaking sea views, guaranteeing privacy and total escape from the daily grind.

Amanpulo, Philippines

    The only property on Pamalican Island, the luxurious Amanpulo resort offers extremely impressive accommodation, with only access to over five kilometres of clean coral sand beach. Designed to resemble indigenous Bahay Kubo homes, Amanpulo's beachside, treetop and hillside villas all feature comfortable decks with hammocks（吊床）from which to enjoy the spectacular views of the greenish-blue sea below. Fill your schedule with Amanpulo's signature aquatic adventures (including diving, windsurfing and sailing), recharge in the award-winning spa or feast upon locally caught seafood – the choice is yours.

Song Saa, Cambodia

    Song Saa's incredible ocean views, and breathtaking sunsets are a very typical example of pure paradise. Its 24 villas – each with their own sea-view private plunge pool – are designed to reflect the natural beauty of Cambodia's coastline; built from recycled wood with straw roofs and driftwood furnishings, these presences are stylish proof of Song Saa's admirable commitment to sustainability（持续）and conservation. You can choose to do as much or as little as you want here, with rainforest tours, island safaris and reef snorkelling just some of the activities on offer that showcase this spectacular destination.

    Following news of the potential for life on the recently-discovered TRAPPIST-1 system, there may be another competitor ready to take its place.

    With the help of the Cassini spacecraft, NASA (National Aeronautics and Space Administration) scientists have picked up the first evidence that chemical reactions are taking place deep below the surface of Enceladus, Saturn's (土星的) sixth-largest moon. This means that there could be life in Enceladus' warm underground seas.

    An early study found that liquid oceans exist miles below Enceladus' surface. But to reveal what is happening down there, scientists must rely on the plumes (股) of water that spray (喷射) through cracks in Enceladus' icy surface. In October 2015, NASA sent Cassini into a deep dive into one of the plumes.

    Cassini's findings, published on April 13 in the journal Science, showed that hydrogen (氢) not only exists on Enceladus, but is also responsible for a chemical reaction between hot rocks and water in the ocean beneath its surface.

    This same process on Earth provides energy for entire ecosystems around volcanic vents (火山口). There, tiny creatures are able to survive without sunlight, using hydrogen and carbon dioxide as fuel in a process known as “methanogenesis (甲烷生成)”.

    The discovery of this chemical energy source on Enceladus means it could be a very good candidate to host life.

    “Confirmation (确认) that the chemical energy for life exists within the ocean of a small moon of Saturn is an important milestone (里程碑) in our search for habitable (可居住的) worlds beyond Earth,” Linda Spilker, Cassini project scientist at NASA, told the Daily Mail.

    Alien life was once only thought possible on habitable planets within the “Goldilocks zone” – far enough from our sun not to be a fireball, but not so far as to be freezing.

    Research on Enceladus is still in its early stages, but the recent findings have important meanings for future exploration.

    “At present, we know of only one genesis (诞生) of life, the one that led to us,” David Rothery, professor of planetary geosciences (行星与地球科学) from the Open University in the UK, told The Telegraph.

    “If we knew that life had started independently in two places in our solar system, then we could be pretty confident that life also got started on some of the tens of billions of planets and moons around other stars in our galaxy,” he said.

    Today, I felt upset, I decided to take a walk even though I didn't know where I would go. The most extraordinary thing happened when I was out on this walk. I saw an old man sitting on a chair. He was a seller of second-hand shoes. He seemed so tired and nobody was buying his shoes.

    I wanted to give him something but I had not brought anything with me. Then, a little girl came toward him. I heard the child say, ''Grandfather, may I polish your shoes?" That old man took pity on her, smiled and he gave her a shoe to polish. The girl said, I polish the shoe because I need money to buy my brother a new school uniform. The old man answered, "Oh, little girl. Just stop doing this. Come with me and I will buy you a uniform.”

    Then they walked to a market (I followed behind) and he bought her a uniform. The girl was so happy. She said, Thank you so much for doing this." Then she left, leaving the old man smiling. He walked away from the market, but I stopped him.

    I whispered in his ear, "You are a hero! Thank you for your kindness!” As I walked away, I glanced back and I could see him still smiling. I was blown away by the kindness I had just seen. Someone who had so little himself was able to show such incredible generosity! Amazing!

    My own sadness had completely disappeared, chased away by the light of this kind act. I began realizing that I have a lot to be thankful for.

    We hope you've finally made your peace with Pluto being downgraded from a planet to an ice dwarf (冰矮星)，because we have some more jarring news for you : It seems your teachers may have been wrong about the number of continents on the earth, too.

    Earlier this year, scientists published a report in the journal of the Geological Society of America detailing an eighth continent called Zealandia, roughly the size of India and almost completely hid itself under the Pacific Ocean east of Australia. Covering all of New Zealand as well as several nearby islands, Zealandia likely spent the best of its above-water days as part of the supercontinent Gondwana before fragmenting off Australia and Antarctica some 80 million years ago. This lost, underwater continent is just beginning to reveal its secrets, making for one of the most promising scientific discoveries this year.

    While researchers have been aware of the 1. 9 million-square-mile mass for two decades, Zealandia has only recently become the object of serious study since the Geological Society paper argued that it fits all the criteria for a proper continent, including a continental crust (地壳)that's distinctly separate from the seabed in terms of elevation, thickness, and geology. A team of 32 scientists from 12 countries just completed their first visit to six dig sites around Zealandia, where they drilled up more than 8,000 feet of sediment cores (沉积物岩心)that will help explain the lost continent's 80-million-year history.

    Because there is no official body that formally recognizes continents, whether or not Zealandia ends up in future geography textbooks will come down to its acceptance by the scientific community at large, possibly with a little help from travelers like you.
