England's highest main-line railway station is in serious trouble, deserted and unmanned since it was officially closed in 1970, Dent, located high in the hills of Yorkshire, wakes up on six summer weekends each year, when a special train unloads walkers, sightseers and people who simply want to catch a train from the highest station to its platforms.

    But even this limited being may soon be brought to an end. Dent station located on the Settel to Carlisle railway line, is said to be surrounded by the most beautiful scenery in the country. But no amount of scenic beauty can save the line because of the British Rail's money problems.

    It is now an open secret that British Rail sees no future for this railway line. Most of its trains disappeared some time ago. Bridges, built a century ago, are falling down. It is not alone. Half a dozen railway routes in the North of England are facing a similar threat. The problem is an old system and an almost total lack of cash to repair it. Bridges and tunnels are showing their ages, the wooden supports for the tracks are rotting（腐烂） and engines and coaches(车厢) are getting old.

    On main lines between large cities, the problem is not too bad. There lines still make a profit and cash can be found to keep them in good condition. But on the country branch line, the situation is different. As track wears out, it is not replaced. Instead speed limits are introduced, making the journey longer than necessary and discouraging travelers.

    If a bridge is dangerous, there is often only one thing for British Rail to do: go out and find money from another places. This is exactly what it did a few months ago when a bridge at Bridling station was threatening to fall down. Repairs were calculated at 200,000 pounds just for one bridge, so British Rail was pleased, and rather surprised when two local councils(理事会) offered half that amount of money.

    E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(伪装)itself as an “important message from a friend. In spite of a weekend of warnings，more than 50 000 computers at about 100 places around the world have been attacked by the virus，computer security experts said on Monday.

    The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被传染的)e-mails. Although the virus causes no serious damage to a computer，its effect was far reaching.

    To make matters worse，a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.

    The Melissa virus comes in the form of an e-mail，usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says，“Here is that document you asked for...,don't show it to anyone else.” Attached(附)to the message is a document file.

    Once the user opens that file，the virus digs into the user's address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(电子数据文件)file. When the user opens that file，the virus sends 60 infected e-mails.

    The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don't know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.

    Are you using a dating App to make friends? How do you know that Ben from London is really 25-year-old? Is his photo taken recently? Is his name even Ben? Dating apps can be tricky to operate, particularly when you're trying to know whether someone is trustworthy, but one thing you can't cheat is your gene, which is why a new dating app is using DNA as a basis for its match.

    A dating app named Pheramor requires all users to hand in a cheek sample, from which a team of in-house scientists using a specially-created tool can queue the specific genes connected with attraction and then identify which users might be suitable. The process works by separating the 11 genes that link to our pheromones（信息素）, the chemical signals that are believed to control one's attraction. Combining this data with the personal information allows the app to make very specific matches.

    “Pheramor uses both your biology and your social technology: we collect your genetic data through a cheek sample and collect your like, dislikes, and interest from your social media introductions like Facebook, Twitter, etc,” the app's website explains. “All of them will be used in our specific software, which is designed to learn what you prefer.”

    The co-founder Brittany Barreto, who has a PHD in genetics added that Pheramor's technology digs deeper than traditional dating apps, making it almost impossible for people to cheat their way to a date.

    The Houston-based app is already up and running but hopes to be officially put into market in February with 3,000 members.

    Most of us have looked up at the stars that fill the night sky and wondered whether we're alone in the universe. Indeed, the question of whether there's life out there has been something humankind's been asking itself for countless years. But thanks to China's Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

    The telescope has a huge round reflector, which measures 500 meters across and has a perimeter(周长)of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST's designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. "Panels can change their positions through connected wires and parallel (关联的) robots. We can control their position with an accuracy of 1mm," Zheng Yuanpeng, chief engineer of the telescope's panel project, told Xinhua News Agency.

    FAST's engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. "There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST's construction, told Xinhua.

    And although it wasn't yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars (脉冲星) have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.
