Tu Youyou, 84, honored with the Nobel Prize in Physiology or Medicine on Oct 5, 2015. She was the first Chinese citizen to win a Nobel Prize in science for her work in helping to create an anti-malaria(疟疾) medicine. In 1967, Communist leader Mao Zedong decided there was an urgent national need to find a cure for malaria. At the time, malaria spread by mosquitoes was killing Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit was formed to find a cure f or the illness. Tw o years later, Tu Youyou was instructed to become the new head of Mission 523. Researchers in Mission523 pored over ancient books to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, over 240,000 compounds(化合物) around the world had already been tested, without any success.Finally, the team found a brief reference to one substance, sweet wormwood（青蒿）, which had been used to treat malaria in China around 400 AD. The team isolated one active compound in wormwood, artemisinin（青蒿素）, which appeared to battle malaria-friendly parasites（寄生虫）. The team then tested extracts（提取物） of the compound but nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she improved the drug recipe one final time, heating the extract without allowing it to reach boiling point.

After the drug showed promising results in mice and monkeys, Tu volunteered to be the first human recipient of the new drug. “As the head of the research group, I had the responsibility.” she explained.

Jennifer Fish, a weather forecaster may soon be replaced by something truly fishier—the shark.

    Research by a British biology student suggests that sharks could be used to predict storms.

    Laura Smith, 24, is close to completing her study on shark's ability to sense pressure.

    If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.

    Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.

    She then used their close relatives, lesser spotted dogfish (猫鲨), for further research at Aberdeen University.

Her work—thought to be the first of its kind to test the pressure theory—resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.

    Miss Smith said: “I've always been crazy about traveling and diving and this led me to an interest in sharks.”

“I was delighted to have been able to research in the area for my degree. I know there's so much more we need to understand—but it certainly opens the way to more research.”

    It has been discovered that a shark senses pressure using hair cells in its balance system.

    At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.

In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish—none of which were harmed. She also used a special lab which can mimic (模拟) oceanic pressure changes caused by weather fronts.

    She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.

    ARCHAEOLOGISTS (考古学家) GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities, then declined and disappeared quietly beneath the dense tropical forest.

    Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.

    This was surprising says an archaeologist, because we had a tendency to romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.

    All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.

    Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.

    "You could walk over the top of a major ruin and miss it, "says an archaeologist who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.

    Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.

    Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. "We still need to dig and hack our way through the jungle, but now we have a very accurate map to guide us."

    Today the Nobel Prize in Literature awarded journalist Svetlana Alexievich approximately $970,000 in recognition of a lifetime of excellence. The 67-year-old author of Voices From Chernobyl and War's Unwomanly Face was praised by the Swedish Academy "for her polyphonic(复调式的) writings, a monument to suffering and courage in our time."

    Prizes like the Nobel inspire much expectations before the announcement. People give their best guesses as to who will win, look back on past winners, and even place bets as if spectators at a Derby(赛马会).

    Literary prizes reward artistic brilliance. They help writers earn a decent living. But is the public's fascination with prize-winning authors healthy? Our impulse seems to increasingly contribute to a culture of turning authors into celebrities, where readers follow the author instead of the book.

    A story should stand on its own, as a considered, complete book, without biographical information from author. It's an idea perhaps best conveyed in Roland Barthes's 1968 essay The Death of the Author. "The image of literature to be found in contemporary culture is arbitrarily centered on the author, his person, his history, his tastes, his passions."

    Nearly 50 years later, a few still agree. "I believe that books, once they are written, have no need of their authors," New York Times bestselling author Elena Ferrante once wrote. "If books have something to say, they will sooner or later find readers; if not, they won't, "she continued. "True miracles are the ones whose makers will never be known."

    ①But the rules for submission for the Man Booker International Prize, for example, strongly encourage authors to "make themselves available for publicity". And the foundation behind the National Book Award requires finalists to participate in their "website-related publicity".

    ② In 2007, a reporter who showed up uninvited at Doris Lessing's house was the first to inform her that she had been awarded the Nobel Prize in Literature. Today the Twitterati came knocking on Alexievich's digital door hour before the award was even official. To be considered for a prize is to be a public figure.

    ③ Harry Potter series author J. K. Rowling, with over 5.6 million Twitter followers, has actively addressed readers through public appearances and social media, revealing much more than we could have imagined when we closed the final Harry Potter book. We now know the house Harry's children will be sorted into, that Dumbledore is gay," Voldemort" is actually pronounced with a silent "t", and a whole host of the other minor and major details about the backstory of the characters.

    The magical world Rowling created in her books—a relatively tight mystery with well-laid clues that led to a satisfying conclusion, which had to prove their merits to the reader based on an internal logic—is being unraveled by her own hand.

    ④ Of course, public attention also has very important benefits for authors. For three months after receiving the 2011 Pulitzer Prize in fiction, Jennifer Egan's A Visit from the Goon Squad sold about triple its print sales from before the prize, Publishers Weekly reports. On Oct. 5, 2010, in the first FT/Oppenheimer Funds Emerging Voices Awards, as Nigerian-born Chigozie Obioma accepted the prize for fiction with an easy smile, his excitement was appreciable. Given the cash prize of $40,000 for each winner, it's hard to downplay the importance of such an honor. Such awards bring necessary visibility and funding to writers facing a literary landscape dominated by white men.

    But our culture of celebrity is often too wrapped up in the way we read: How might the meaning of a work change if the author really didn't grow up in a poor neighborhood, or if he or she was abused in childhood? Readers studied the author's life as if it were the key to interpreting his or her novels.

    Behind our fascination is the question that drives all such questions: What did the author intend? By all means, let us praise brilliant work and in doing so trust that the author has already told us enough, and that the story he or she meant to tell ended with the final page.

    People have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, jiving for around 50 to 70 years.

    Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

    According to the research, the extra copies of the gene improved the animal's sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

    "An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals," the study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.

    This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox (悖论)”". Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.

    The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place.

    "Nature has already figured out how to prevent cancer," said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. "It's up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people."
