Phil White has just returned from an 18,000 ­mile, around­ the ­world bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised ￡70,000 for the British charity, Oxfam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out if he has broken the record or not.

    White set off from Trafalgar Square, in London, on 19th June 2004 and was back 299 days later. He spent more than 1,300 hours in the saddle (车座) and destroyed four sets of tyres and three bike chains. He had the adventure of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing! Just a bike and a very, very long road.

    The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escape with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1,000 kilometres he battled against the wind that was constantly pushing him. This part of the trip was slow, hard work and depressing, but he made it in the end. Now Mr. White is back and intends to write a book about his adventures.

BLOOD DRIVE ＆ MARROW（骨髓）REGISTRATION

    "These patients deserve a chance at a normal, happy future and they rely on the kindness of the strangers to make that happen.

    — Daisy, Isabelle's Mother

    Isabelle is the daughter of Daisy and Saman Mirzaei. In January 2008 Isabelle was diagnosed（诊断）with a genetic blood disorder，beta thalassemia. Isabelle's body is unable to produce healthy red blood cells. As a result, Isabelle has been receiving blood transfusions (输血) every 4-6weeks since she was 11 months old. A lifetime of regular transfusions can lead to serious medical problems. Her only chance at a normal, healthy life is to have a marrow transplant.  Isabelle is an only child, so doctors have started a search for an unrelated marrow donor through The Match Registry. The Mirzaei family asks that you consider helping patients like Isabelle by registering to be a marrow donor and give the gift of life, the gift of blood.

    BEIJING (News Agency) — Children in China today spend five times more money than their parents did when they were young.

    So what are all these children buying? The list is long: iPads, cell phones and jeans are typical items that children “have to” buy. And they will do anything to get them. They ask their parents over and over until they buy them.

    But parents also need to take the blame(责备) for spending so much money. They want their children to have the best things. They end up competing with other parents over whether their children have the latest products.

    So it's no wonder children find it hard to learn the importance of saving money rather than spending it all the time.

    And it's hard to save when companies use advertising (打广告)and clever slogans (口号) to encourage young people to buy their products. They even encourage children to keep asking their parents for something until they get it.

    Today, you don't even need to have money in order to buy something. Banks give out credit cards and loans (贷款) all the time, so people are saving less and less. We are used to carrying lots of money around. And if you don't have much, you can always borrow some.

    But this hasn't always been the case. When our grandparents were young, there was very little money and everyone had to save hard for things they bought. They only bought things they needed, not things they just wanted.

    The older generation made the wise expression, “Money doesn't grow on trees.” This is as true now as it was 50 years ago. They give money a great deal of value. And we all have a lot to learn from them.

    Tiny as they are, bats have the ability to “see” in the dark by using a special skill called echolocation(回声定位法). They make noises and wait for sound waves, or an echo, to bounce(反弹) back off objects. They can tell the distance of various objects by how quickly the sound waves bounce back off them. If no sound bounces back, they can then fly forward.

    This special ability has been simulated in the human world for a long time, such as in submarines and planes, whose sonar(声呐) systems are somewhat similar to echolocation. But apart from helping vehicles “see” where they are, what if blind people could use echolocation for themselves? It turns out, some already are.

    American Daniel Kish, who is blind, is known as “Batman”. This isn't because he walks around in a cape and a mask, but because he has a bat-like ability to locate where he is through sharp clicks he makes by moving his tongue against the roof of his mouth. Kish is so skilled at echolocating that he can ride a bike and hike on his own.

    Recently, research carried out at the University of Durham in England shed some light on the power of human echolocation.

    Kish worked with a group of scientists who studied the way blind people listen to the echoes that they produce from clicks.

    The team, which conducted experiments with other volunteers, found that people were capable of hearing even very faint echoes, ones far fainter than had been previously thought.

    Speaking to The Independent, Lore Thaler, lead scientist of the group, said, “We found that in some conditions, they were really faint – about 95 percent softer than the actual clicks, but the echolocators were still able to sense this.”

    Andrew Kolarik of the University of Cambridge is another expert in echolocation. Reacting to the Durham study, he told BBC News that echolocation “can be very useful at providing information at face or chest height” and could help people “avoid objects like low hanging branches that might not get detected by the cane or a guide dog”.

    Although Kish's skill is remarkable, there's hope for other blind people who want to use echolocation. According to BBC News, echolocation is a skill blind people can acquire and develop, just like learning a language. As Kolarik said: “Teaching echolocation skills could provide blind people with the means of exploring new places.”

    It has been described as art by some people, but to others it's an ugly part of modern life. What is it? Graffiti (涂鸦), of course. Look around cities in the UK today and you can see graffiti on buildings, walls, doors and even on buses or trains that have stayed in one place for too long. But where modern technology creates a problem, it also finds a way to deal with it. Last week, The Weekend West was shown around the factory of a small but successful company, Hubdean.

    Hubdean's achievement is a series of special paints which are graffiti-resistant. How do they work? It couldn't be simpler. Take any graffiti-covered surface. First, a treatment called Agproclear is used. Then, using a very hot pressure jet (压力喷嘴), this treatment is taken away and the graffiti disappears at the same time. Now you have a clean wall. But before this clean wall can be painted on by graffiti lovers, a new product, Agproshield, is used. This paint has a special surface which gives it two important advantages. Firstly, spray paint (喷雾颜料) won't stick to the surface very well, and secondly, the whole surface can be cleaned very easily, just using water. Once the surface is painted, no specialist equipment is needed to keep the area clean and graffiti-free.

    Not surprisingly, Hubdean's products are used by both local governments and private companies all over the UK, and now orders are being received from around the world. This brings the company a problem, however. Can they increase production to satisfy the needs? Of course, they can build a second factory or work with a large international company to make their products. The future is looking good for Hubdean!

Tests have shown robots can diagnose heart problems in as little as four seconds, as a review of artificial intelligence (AI) finds machines are now as good at spotting illness as doctors.

Analyzing a patient's heart function on a cardiac MRI (心脏磁共振成像) scan currently takes doctors around 13 minutes. But a new trial by University College London (UCL) showed an AI program could read the scans in less time with equal accuracy. There are approximately 150,000 such scans performed in the UK each year, and researchers estimate that fully using AI to read them could save 54 clinician-days (临床天数) at each cardiac centre per year. So it can make up for the shortage of doctors.

It is hoped that AI where computer systems are able to learn from data to identify new patterns with minimal human intervention will transform medicine by helping doctors spot diseases such as heart disease and cancer faster and earlier. However, most scans are still read by specially trained doctors.

Dr Charlotte Manisty, who led the UCL research, said, "Cardiovascular MRI offers in- comparable image quality for assessing heart structure and function. However, current manual analysis remains basic and outdated. Automated machine techniques offer the potential to change this and completely improve efficiency and accuracy, and we look forward to further research that could confirm the superiority to human analysis."

She added, "Our dataset of patients with a range of heart disease who received scans enabled us to demonstrate that the greatest sources of measurement errors arise from human factors. This indicates that automated techniques are at least as good as humans, with the potential soon to be 'super-human'—transforming clinical and research measurement precision."

Professor Alastair Denniston said, "Within those handful of high-quality studies, we found that by deep learning AI could indeed detect disease ranging from cancer to eye disease as accurately as health professionals. But it's important to note that it did not absolutely exceed human professional diagnosis. "
