Guided Walking Week April 2016

          Dates: April 30th-May 7th 2016

          Location: Abdet, Costa Blanca

         A week of guided walking in the mountains around Abdet. Highlights include the climbing of Valencia's highest summit (Sierra de Aitana), traveling completely around the impressive Puig Campana, and several explorations in the Sierra de Aitana. Ancient trails lead through spectacular canyons(峡谷) to abandoned settlements situated high in the mountains. You will discover the snow trader routes which lead from the incredible snow holes high in the mountains down to the villages and towns on the coast. These years, golden eagles have made a return to this area, and you may also see other animals—wild goats, foxes, wild pigs and red squirrels.

         As part of the week you are invited to help clear some local walking paths. This involves clearing collapsed walls and rocks, cutting back fallen trees. This is of course optional and is just for half a day, it's actually great fun!

    Venom (毒液) from a local scorpion (蝎子) in Cuba is being used by Cuban scientists as an effective weapon to fight cancer. The venom, with stopping pain, anti-inflammatory (炎症) and anti-cancer properties, is the active ingredient in the medicine “Vidatox 30 CH,” which can be used to treat liver, brain, lung and other cancers. The treatment has been successfully used for more than four years in humans after being first tested in biological models. Labiofam, a Cuban laboratory, has breeding (繁殖) centers for both the Red Scorpion and Blue Scorpion. Each month, some 30,000 scorpions in Las Minas town, 270 km east of Havana are made to give the venom. After two years, the scorpions are released back into their natural habitat.

    Denyer Sanchez, a biologist from Labiofam, explained that the conditions are adjusted for reproduction, proved by the high number of breeding female scorpions. He said when the offspring (后代) becomes able to live in the environment, we release them because they do not have the necessary size yet to remove their venom, said Sanchez. Sanchez also said that there is still much to research on the exploitation process of scorpions, such as female death rate or the ability to survive of the released scorpions.

    Cuban research on the scorpion's venom began at the end of 1980s in Guantanamo province, the island's eastern tip, where a group of biologists and doctors became interested in the stories told by the peasants about the venom's benefits. However, the first discovery was made by Cuban biologist Misael Bordier. In 2001, Bordier visited Mexico's National Autonomous University (UNAM) and presented the research progress in a professional journal. Bordier died in 2005, one year before Cuba's Industrial Property Office gave Labiofam the rights to exploit the patent related to the venom.

    Daniel was born in New Orleans, LA., in 1962, slow to walk and talk, and short. He was the tiniest in his class, but he developed a warm, outgoing nature and was popular with his peers(同龄人). And he became skillful at sports.

    Baseball gave him his earliest challenge. He was an excellent players in Little League. At graduation, the coach named Daniel the team's most valuable player.

    His finest hour, though, came at a school science meeting. He entered an exhibit explaining how the circulatory system works. It was traditional, especially compared to（与…相比）the modern, computerized, blinking-light models entered by other students. My wife, Sara, felt embarrassed for him.

    It turned out that the other kids had made their exhibits. As the judges went on their rounds, they found that these other kids couldn't answer their questions. Daniel answered every one. When the judges awarded the Albert Einstein Plague for the best exhibit, they gave it to him.

    By the time Daniel left for college he stood six feet tall and weighed 170 pounds. He was in superb condition, but he quit baseball for English literature. I was sorry that he would not develop his athletic talent, but proud that he had made such a satisfactory decision.

    One day I told Daniel that the great failing in my life had been that I didn't take a year or two off to travel when I finished college. This is the best way, to my way of thinking, to broaden oneself. Once I had married and begun working, I found that the dream of living in another culture had disappeared. Daniel thought about this. After graduation, he worked as a waiter at college, a bike messenger and a house painter. With the money he earned, he had enough to go to Paris.

    The night before he was to leave, I tossed in bed. I was trying to figure out something to say. Nothing came to mind. Maybe, I thought, it wasn't necessary to say anything.

    Since his students began using Quizlet, English teacher Tristan Thorne has noticed an improvement in their ability to learn and use new words. Quizlet is a learning App, a computer program you use on your mobile phone. It can help users build and test their knowledge of English words. Quizlet has word sets for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.

    Thorne teachers at Columbia University in New York City. Thanks to learning Apps, Jeff Strack, another English teacher, has also notice improvement in his students' ability to remember information. He teaches at Hostos Community College, also in New York. He and Thorne are part of a growing number of language educators adding mobile Apps to their classes.

    Strack and Thorne seem to agree that the days when teachers would not permit the use of mobile phones are gone. When they use Apps, language learners communicate more differently than in a traditional classroom. Users act on or respond to something, instead of just listening to new information.

    Thorne believes that Apps can help learners become more active in learning. For example, each week, his students are required to add vocabulary words into Quizlet for others to use. He says some Apps also make it easy for students to know their language strengths and weaknesses.

    The biggest improvement Strack has seen in his students is that they are much more active inwhole-class or small-group discussions. “Apps let all students take part in the activity, whether it's a game, quiz or practice activity.” he says.

    Many existing learning Apps are designed for students of all ages and levels. Some are designed for group activities. Some support independent learning. Still some are good for homework. Thorne says he especially likes Quizlet and three other Apps: QR Codes, Socrative and Evernote.

    The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.

    Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

    I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

    The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote.

    "You must properly respect what you are after and shoot it cleanly and on the animal's own territory(领地)。You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals, Hunting is not a cruel and senseless killing - not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people."

    I can understand such beliefs, and can compare these hunters with those who hunted lions with spears(矛) and bravely caught them by the tail. But this is very different from many tiger-shoots I have seen, in which modern weapons were used. The so-called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

As the pandemic makes clear, cities are possibly humanity's greatest invention, but cities with huge populations also make us easily suffer from the rapid spread of disease. Yet humans aren't the only species that face this problem. Honeybees have lived social lives for tens of millions of years, making them some of the most experienced in the battle against infection. And over time, natural selection has given them quite a few impressive strategies for reducing transmission within bee groups.

However, these strategies are not enough to prevent every threat. Honeybees are battling their own global disease, for which they were totally not prepared. A parasitic mite (寄生螨) originally existed only in the groups of Asian honeybees, but later jumped to infect Western honey bees. Today, it has spread to every region where honeybees are kept except Australia and a handful of remote islands, quickly becoming a global disease of the bees.

If left untreated, a group of bees will typically die from the mites within two years. These infections, plus farm chemicals and poor nutrition, have forced beekeepers to struggle to keep their bees alive. Of the 2.6 million honeybee groups in the US, over half of them have parasitic mite.

And that's only the count of those bees that are tested and reported; the actual numbers are likely much higher. Beekeepers have still managed to slowly increase the number of groups they keep, on average, but at a much higher cost.

Western honeybees did not grow with parasitic mite, and the Western bees lack the behavioral features those Asian honeybees have, like permanently burying the members infested by parasitic mite and, perhaps the most extreme strategy, where the bees are so sensitive to parasitic mite that they completely die as soon as infected, sacrificing themselves to prevent the mite from reproducing.
