“Students who are used to working on well-structured problems struggle when confronted with the multiple challenges of more complex tasks.” writes Professor Ogilvie (Iowa State University), who not only assigns context-rich problems in his course but has also begun researching their effect on the problem-solving strategies adopted by students. The problems are implemented in a computer-assisted learning environment of his own design. When a student group logs into the system, a context-rich problem is presented with a selection of information resources that may or may not be relevant. The students are asked to write not just the solution, but describe their thought process in categories corresponding to the typical stages of expert reasoning: qualitative analysis, identification of relevant concepts, ongoing monitoring (evaluation of the solution as it progresses), and validation of the solution obtained. The beauty of this system is that it not only guides the student into a more ‘expert’ mode, it also tracks the time spent at each step, the resources accessed, and so on.So, has this learning environment helped train a new generation of experts?The answer is yes, with some caveats. First, as with any group project it is hard to track which students are working and which ones are learning. Second, Ogilvie’s course presents only five such problems to the students. (There is still all the core material to get through, after all!)As for the results, there is some good news and some bad news.In the first problem of the course, students completed the ‘qualitative analysis’ section an average of ten minutes before completing the assignment. In the last problem, this section was completed about twenty minutes beforehand. Another encouraging point is that very few students wasted time reading all the available information in later problems. “Taken together, the student groups show some progression towards expert-like behavior” Ogilvie writes, “earlier qualitative analysis and more selective requests for information.” By the end of the course, students were also identifying the most relevant concepts earlier.In other words, the students grew more likely to think about the problem before attacking it. That’s the good news!The bad news is that there is no evidence for improvement in one of the most important aspects of expert reasoning: ongoing monitoring. Monitoring is a form of critical thinking, the general (and highly useful) cognitive skill of evaluating the quality of information. Experts in a field will examine their solutions repeatedly as they work them out. Have any of their initial assumptions been violated along the way? Is the solution making progress, or is it getting sidetracked? Is the math becoming simpler or more complicated? If an expert senses that a solution isn’t working well, they may abandon it to look for a better approach.In all fairness, this is also probably the most difficult skill to measure. Computer tracking can only show that students usually filled in the “monitoring” summary right before completing the assignment. No doubt this skill can be taught as well, but it might lie beyond the scope of computer instruction. I still vividly remember one of my professors taking only ten minutes to solve a physics problem that had taken me hours to work out. Perhaps the lesson of monitoring solutions can only be learned by sincerely regretting the time you just wasted.Note: 1groups.physics.umn.edu/physed/ … rch/CRP/crintro.htmlCitation: “Understanding Student Pathways in Context-rich Problems” by Pavlo Antonenko, John Jackman, Piyamart Kumsaikaew, Rahul Marathe, Dale Niederhauser, Craig Ogilvie, and Sarah Ryan is available online at xxx.arxiv.org/abs/physics/0701284By Ben Mathiesen, Copyright 2007 PhysOrg.com.

Citation: Can expert reasoning be taught? (2007, February 9) retrieved 18 August 2019 from https://phys.org/news/2007-02-expert-taught.html In addition to mastering a large body of knowledge, successful researchers must acquire a host of high-level cognitive skills: critical thinking, “framing” a problem, ongoing evaluation of the solution as it progresses, and ruthless validation of one’s final answer. Some students pick these skills up on their own as they advance towards their degree, especially those who participate in research, but they rarely appear in a curriculum. Students working on a context-rich problem fall naturally into two groups. Teams above the line demonstrate expert-like behavior, in that they completed their qualitative analysis of the problem before accessing the relevant information and submitting a solution. Those teams below the line demonstrate novice-like behavior, in that they appear to read through as many resources as they can before attempting a solution and submit their analysis of the problem only after a solution has been recognized. Credit: Craig Ogilvie Expert mathematicians stumped by simple subtractions Explore further Professor Craig Ogilvie of Iowa State University has developed a problem-solving environment that not only encourages students to practice these skills but also monitors their progress.As a physics professor, I often find myself torn between competing educational goals. On the one hand, most courses have a laundry list of fundamental theories and techniques that must be taught if the students are to advance further in the subject. On the other hand, there are a number of higher cognitive skills that I would also like to emphasize. The cognitive skills are more useful in life, but how much subject matter can I reasonably sacrifice to make room for teaching them?Traditional teaching methods reinforce the course content by assigning busy work — practice makes perfect, after all. Homework assignments consist of simple “plug and chug” problems that students can solve easily by finding the appropriate formula. While such assignments do help students learn the main topics of a course and prepare for the inevitable final exam, they promote a very limited style of problem-solving. More importantly, they provide little motivation for students to absorb the lessons of scientific thought.One solution is to raise the bar on the problems. Why not strip them of their hand-holding language, and present information in a more realistic setting? The result may be too difficult for one student, but is probably suitable for a group of students. Researchers in physics education at the University of Minnesota, for example, have created an archive of such context-rich problems for their introductory physics courses1. Context-rich problems force students to practice some of the cognitive skills used by experts, in particular the skill of analyzing a problem qualitatively before looking for the proper formula.I don’t wish to bore my readers, so I will present the briefest possible example of this qualitative analysis. When confronted with a collision problem, students should ask themselves whether friction is an important factor before they look up Newton’s laws. Figuring out how a problem relates to known principles is the first step taken by experts when they approach a new situation. This document is subject to copyright.

What will Google bring to the project? Google will work on core platform development. Google’s Dan Clancy, Director of Research, said Tuesday, “We are taking our learnings from Course Builder and applying them to Open edX” for the latter’s new platform.By Course Builder, Clancy is referring to the open source experimental platform that Google started in 2012 with the similar spirit of support for online learning, providing the tools for those who want to create an interactive online course. Though it was Google’s first step into this kind of project, Course Builder attracted a community of education-focused people around the world. In 2014, however, the edX alphabet soup is going to have a key main ingredient, yet another catchy phrase to watch, called MOOC.org. This will go live in 2014 with courses.”We look forward to contributing to edX’s new site, MOOC.org, a new service for online learning which will allow any academic institution, business and individual to create and host online courses.” said Clancy. For those involved in Course Builder, questions remain as to what next year’s MOOC.org means for them. Google’s Clancy said Google will provide “an upgrade path to Open edX and MOOC.org from Course Builder.”According to the Course Builder site, in a notice titled Hi Course Builder community, “As we transition our focus to Open edX, we will minimize Course Builder feature development. However, we are committed to providing support to current and future Course Builder users in the interim.” For anyone who has customized Course Builder, “we cannot guarantee that these will transfer to Open edX. However, Open edX has a customization framework called XBlocks that may address some of these needs. Additionally, as an open source platform, Open edX can be customized at the source code level.”Meanwhile, Anant Agarwal, president of edX, welcomes the Google move because of the opportunity to work with Google’s world-class engineers and technology, which “will enable us to advance online, on-campus and blended learning experiences faster and more effectively than ever before.” The new site is to invite contributions not only from schools but businesses and individual course authors and instructors. MOOC is shorthand for Massive Open Online Courses. (Phys.org) —Free online courses continue to be a work in progress as the next upheaval in education. Google will be advancing progress momentum, based on Tuesday’s announcement from Google Research: Google is joining the Open edX platform. To get some of this lingo soup out of the way, we start with Open edX, which is a platform for creating courses that can be taken by anyone with Internet access. Behind this open source learning platform is edX, a group of 28 institutions, the xConsortium. Founded by Harvard and Massachusetts Institute of Technology, edX is dedicated to transforming online and campus learning. A nonprofit, edX distributes online courses for free.

The researchers, Yi-Fan Zhu, Xin-Ye Zou, Bin Liang, and Jian-Chun Cheng, from Nanjing University in China, have published their paper on the acoustic one-way tunnel in a recent issue of Applied Physics Letters.”One-way acoustic devices are believed to have deep implications in various situations by breaking through the conventional concept that sound always propagates symmetrically along a given path,” Liang told Phys.org, noting some of their previous related work here, here, and here. “The realization of an acoustic one-way tunnel goes further beyond simply breaking through this limitation, and enables one-way acoustic manipulation when the acoustic path is kept totally open to other entities. We envision our design with such novel capability and tunability to offer more design possibilities and have promising application potential in various scenarios where special manipulation of sound is desired.”The new tunnel takes advantage of the extraordinary reflection properties of recently developed acoustic metamaterials, which force sound waves coming from one direction to make a U-turn in the 10-cm-wide tunnel and travel back out. By strategically positioning two different acoustic metamaterials with different reflective properties along the insides of the tunnel, the researchers could asymmetrically manipulate the sound waves so that only those coming from one direction are reflected, while those coming from the other direction can pass through.

DOI: 10.1063/1.4930300 (Top) When an acoustic wave enters from the side of the tunnel with “acoustic metamaterial 1” (AM1), it makes a U-turn and reflects back out, whereas the majority of an acoustic wave traveling from the other side with “acoustic metamaterial 2” (AM2) can pass through. (Bottom) Simulated acoustic field patterns for the negative direction (ND) that does not allow acoustic wave passage and positive direction (PD) that does. Credit: Zhu, et al. ©2015 AIP Publishing The researchers printed the acoustic metamaterials using a 3-D printer with ABS plastic, which is the same material used to make Legos. They then imprinted multiple tiny grooves into the two metamaterials with different groove periods (0.84 cm and 2.36 cm), which gives them different reflective properties. The tailored groove designs affect the sound waves differently depending on which direction they’re coming from, which ultimately leads to the asymmetric wave manipulation and one-way transmission. Although other methods have been developed for the unidirectional control of sound, all of the previous designs have relied on bulk materials. The drawback of bulk materials is that they partially block the tunnel so that it’s not fully open to other entities, such as light and heat. Because the new tunnel allows light and heat to freely pass through from both directions while blocking the transmission of sound in one direction, it could lead to anti-noise windows that are see-through and ventilated, and may inspire research into the unidirectional control of other kinds of waves. “The acoustic one-way open tunnel may also enable conceptual devices like novel ventilating channels that block sound from one side but allow air or heat flow to pass freely, or serve as building blocks of more complex systems that reduce the reflected wave but do not affect the passage of other objects, which may find extensive applications in the fields of noise control or biomedical imaging/treatment, etc.,” Liang said.In the future, the researchers plan to improve the performance of the one-way open tunnel, for example by boosting the efficiency and broadening the bandwidth. They also want to devise methods for manipulating sound in even more unprecedented ways beyond the one-way manipulation demonstrated in the current work, while keeping the acoustic path fully open.

Credit: Zhu, et al. ©2015 AIP Publishing Designing an acoustic diode (Phys.org)—Scientists have designed and built an acoustic one-way tunnel that allows sound to pass through in one direction only while blocking it from passing through in the opposite direction. The tunnel is completely open to light and heat, which can pass through in both directions, but sound waves are blocked in one direction due to acoustic metamaterials placed on the sides of the tunnel. The acoustic one-way tunnel has potential applications for anti-noise windows and vent ducts, as well as medical ultrasound.

Read the whole story: Forbes From measuring shopper satisfaction to detecting signs of depression, companies are employing emotion-sensing facial recognition technology that is based on flawed science, according to a new study. … A new study in the journal Psychological Science in the Public Interest is challenging the basic science behind emotion-sensing tech and its claims to be able to infer a person’s mood from their facial expressions. The scientists behind the research, who hail from Northeastern University, Caltech, Ohio State, and the University of Wisconsin – Madison, also make clear precisely what’s at stake. If the idea of having your face recorded and then analyzed for mood so that someone can intervene in your life sounds creepy, that’s because it is. But that hasn’t stopped companies like Walmart from promising to implement the technology to improve customer satisfaction, despite numerous challenges from ethicists and other consumer advocates.
At times we all feel that life is very complicated but only a few of us are able to express the dilemmas in right manner. Artist Aarti Zaveri expresses the same through her art work at upcoming United Art Fair. The artist believes that, it is very easy to complicate a beautiful life and at the same time very difficult to simplify the essence of life. These thoughts are reflected in her paintings by the use of bold and vibrant colours. She has created a body of work around these figurative expressions. One can sense the attempt to convey her deep thoughts through the use of symbols and signs in a subtle and minimal manner in each painting. The canvas reflects the basic complexity of a human to find answers in the outside world when all the answers needed are already present within us.The last edition of her installations in United Art Fair, were based on the theme, how a person wears a mask to conceal various truths of life. Which was based on artistes belief that life is a paradox and a puzzle, the ones who solve it, makes it simple and the rest remains to be just a part of the puzzle.With her recent work she is giving out a beautifull message that everyone has an option to make their lives easy or difficult, it depends on us what we choose.
Kolkata: Police arrested a senior official of a nationalised bank on charges of sanctioning loan against “fake documents” furnished by a borrower. Police said a complaint was lodged against the 52-year-old official, Om Prakash Ram, with the Bidhannagar East Police Station on December 30 in 2017. Based on the complaint, police had initiated a probe and preliminary investigation revealed that the document against which the loan was sanctioned was fake. Also Read – Heavy rain hits traffic, flightsHe is a resident of Haridevpur area. A police officer stated that some borrower showed fake documents to get a loan and the official, who was then the manager of the particular branch of the nationalised bank, sanctioned it. It was alleged that “the man being manager of the branch was instrumental to materialise the loan without proper verification”.Based on the allegations, police had initiated a case under several sections of the Indian Penal Code (IPC) on charges of Forgery for purpose of cheating (468 IPC), cheating and dishonestly inducing delivery of property (420 IPC) and acts done by several persons in furtherance of common intention (34 IPC). Sources said the police questioned the person in this connection and he was arrested after discrepancies found in his statement.

Kolkata: Mystery has deepened on what prompted Ramakrishna Math and Mission to cancel the scheduled visit of Chief Minister Mamata Banerjee to Chicago. Banerjee was scheduled to visit Chicago to attend a programme of the Vivekananda Vedanta Society of Chicago of the Ramakrishna Math and Mission on August 26 to mark the 125th anniversary celebrations of the historic Parliament of World’s Religions that had catapulted Vivekananda to the world stage… and to a permanent place in global history. Also Read – Heavy rain hits traffic, flightsAlthough the Vivekananda Vedanta Society of Chicago mentioned in a letter to the Chief Minister that the programme has been cancelled due to the death of Assistant General Secretary Swami Abhiramananda and other “unforeseen difficulties”, it is not clear to many how his death in Howrah could be the reason behind cancelling the programme in Chicago.According to sources, Ramakrishna Math and Mission succumbed to the pressure of the Ministry of External Affairs as Prime Minister Narendra Modi is himself visiting Chicago to attend a programme on the 125th anniversary of the Parliament of World’s Religions that has been arranged by a Hindu organisation. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedIn the letter to the Chief Minister dated June 11, Vivekananda Vedanta Society of Chicago President Swami Ishatmananda stated, “We are thankful that you accepted our invitation to attend our programme celebrating the 125th anniversary of the Parliament of World’s Religions, which was to be held at the Art Institute of Chicago on August 26.”Explaining the reason behind cancellation of the programme, Swami Ishatmananda maintained in the letter, “We are sorry to inform you that due to the sudden demise of Swami Abhiramananda, Assistant General Secretary, Trustee of Ramakrishna Mission and member of the Governing Body of Ramakrishna Mission, as well as unforeseen difficulties, we have had to cancel the August 26 programme. We remain ever thankful for your support and regret any inconvenience this may cause you.” It may be mentioned that the body of Swami Abhiramananda was found in the river Hooghly near a ghat at Belur in Howrah on June 8.The Chief Minister’s scheduled visits to China and Chicago were cancelled within a gap of a few days and it prompted political observers to suspect that the developments are not just mere coincidences. Instead, they are conjecturing that there is a “strong enough political reason” behind the cancellation of Banerjee’s trip to Chicago as her visit was scheduled within a few days of Modi’s visit.Interestingly, the Chief Minister’s visit to China had to be cancelled just a few hours ahead of the journey on Friday as “the political meetings at appropriate level” could not be confirmed.This happened despite the fact that External Affairs Minister Sushma Swaraj had a couple of months ago recommended that Banerjee lead a delegation to China under the Union Government’s Exchange Programme with the Communist Party of China’s International Department.So political experts are considering “negligence” in the Centre’s part for “lack of confirmation of the meeting at the appropriate level”.It may be mentioned that the Chief Minister’s Chicago trip has been cancelled when her government has decided to take up character building programmes in schools as a part of the celebration of 125 years of Swami Vivekananda’s address at the Parliament of World’s Religion in Chicago.A programme will also be organised at Vivekananda Yuva Bharati Krirangan in which 1 lakh students and youths will be participating.

Kolkata: The state government will soon fill up the vacancies in the Mass Education Extension and Library Services department, Siddiqullah Chowdhury, Minister of State of the department said on Saturday.Chief Minister Mamata Banerjee tweeted: “Today is International Literacy Day. The issue of literacy is a key component of the UN’s Sustainable Development Goals and the UN’s 2030 Agenda for Sustainable Development. Our Govt is committed to spreading the light of education among all.” He was addressing a gathering to celebrate the International Literacy Day at Rabindra Sadan on Saturday afternoon. He said as per the 2011 Census, the literacy rate in Bengal is 76 percent but has gone up by at least another 9-10 percent. According to 2011 Census, literacy rate in Bihar is 55 percent, Odisha is 69 percent, Assam is 62 percent and Jharkhand 60 percent. He said steps have already been taken to expedite the literacy drive in all the districts. In Bengal, West Midnapore has the highest literacy rate that is 92 percent while in Uttar Dinajpur and Purulia, the rates are 69 percent and 64 percent respectively.

Winter leaves fashionistas with restricted options of experimenting with colours, designs and cuts but one can try out some smart ways like layering and opting for classic pieces to make winter wear stylish.As the Seventies make a comeback at the International Fashion front this season (Chloe, Marc Jacobs, Alexander Wang), the leather dress with its sculptural shape and a rock-chic look, has become a must have in our Fall/Winter 2016-2017 wardrobe. Also Read – Add new books to your shelf Layering of garments is the most creative and yet the safest way to look classy and stylish during winters. All you need is a strong sense of personal style and a tad bit of creative genes within you, and you can have a lot of fun mixing and matching pieces from your wardrobe, even those which have been rendered so very last season! While planning the winter wardrobe one cannot ignore the trends of the season and what’s trending this season are the patches, badges and embroideries. Also Read – Over 2 hours screen time daily will make your kids impulsive For those who are not so experimental and more adhering to the classic looks, we recommend few classic pieces to them, to form looks which are tried and tested as well as instantly chic. Styles such as a knee length wool coat – one of the most classic winter fashions, a knit cardigan – ideal for layering under heavy wool coats in the winter. When it comes to winter fashion, neck accessories play a very essential role. They can add that extra zing to the ordinary winter ensembles for the day. With sportswear trending in the business of fashion, bomber jackets are no more associated with so much of masculinity and mundane look. In fact it has transcended in daring and feminine range of colours and designs for those who care to explore beyond the classic black look. When all is settled, we can come down to basics – the bottom wear. Choose from the stylish lycrated leggings with zipper details, enzyme washed and beautifully crafted denims and formal trousers. When worn over leg warmers you can still enjoy our embellished and embroidered denim shorts and keep those biker boots handy to complete the look.
Kolkata: After the recent introduction of the Krishak Bandhu scheme which will grant Rs 2 lakh to the kin of farmers after their death irrespective of the cause, the farmers of Bengal are set to receive another good news. The state government has decided to expand the National Agriculture Market (eNAM) scheme to the markets of Bengal, in order to end the plight of small-scale, marginal farmers.Speaking at an event organised by the Merchants’ Chamber of Commerce and Industry (MCCI) on ‘Driving Agri-Business through electronic National Agriculture Market (eNAM) Platform & Farmer Producer Organisations (FPOs)’ on Monday, the agriculture advisor to the Chief Minister, Pradip Mazumdar said: “In a country where agricultural distress is at an all-time high, it is highly important to find a modern solution to address the problem of wastage of surplus produce. eNAM gives the platform to small-scale farmers to meet international buyers and also to sell their produce at the best possible price.” Also Read – Bose & Gandhi: More similar than apart, says Sugata Bose”We are all used to the concept of e-shopping, where we can buy products online while sitting comfortably in our living room. The same concept has been applied to eNAM, which opens up bigger opportunities for farmers who are often neglected,” Mazumdar said. The farmers of Bengal, who live even in the remotest part of the state, are not oblivious to the fact that they need to adopt modern technology or change the way they function. “In fact, the rate of adoption among Bengal farmers is extremely high but all they need is a bit of hand holding and the right kind of training,” he maintained. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataThe state at present has 17 large markets under the scheme of eNAM, under which 10,798 farmers, 1,742 traders and 62 Farmer-Producer Organisations (FPOs) have registered. Commodities like fruits, vegetables, sugarcane and jute are mainly dealt with on eNAM. The state government aims to double the numbers at the end of this year. Speaking about the hurdles faced by the scheme, Rajesh Kumar Sinha, secretary of West Bengal Agricultural Marketing, said that the eNAM scheme is giving efficient outcome in other states like Andhra Pradesh and Telangana but not in Bengal. “The scheme is not going good for small and marginal farmers with very small amounts of produce. For them, there is a need for an aggregation system that collects small lots. Even grading and assaying of vegetables and foods has not been done well in the state. We need a transparent and robust online interface for buyers and sellers to benefit,” he said. The state government has already spent around Rs 40 lakh on the scheme and another 40 lakh is needed to keep the scheme up and running. “Within a couple of weeks or months, eNAM will be getting the additional budgetary support from the government. This is a good scheme but it has teething issues,” Sinha added.
Undergoing bariatric surgery to combat obesity can prevent women from developing womb cancer also known as uterine or endometrial cancer, claims a study. The findings, led by scientists from the University of Manchester, showed that women who had gastric sleeve or bypass surgery for obesity found that precancerous tissue in their womb reverted to normal tissue when they lost weight. “For super obese women, quick access to weight loss surgery has benefits beyond improving diabetes and risk of heart disease. It can also reduce womb cancer risk,” said Emma Crosbie, clinical senior lecturer from Manchester. Also Read – Add new books to your shelf”Losing weight through dieting is also likely to be effective, but we know that dieting is very hard to do and weight lost is often re-gained,” she said. In the study, published in International journal of Cancer, the team examined nearly 100 women with an average BMI of over 50 – considered to be super obese – had biopsies taken from their wombs during gastric sleeve or bypass surgery. Obese post-menopausal women produce oestrogen from their fat stores. But as they no longer ovulate, the lack of progesterone allows the cells in the womb to grow, which increases the risk of cancer. Also Read – Over 2 hours screen time daily will make your kids impulsiveInflammatory responses and insulin production are also changed in obese women and can cause cells in the womb to grow. “Because the reversal of precancerous changes in the womb was so quick, we think the metabolic consequences of weight loss surgery was crucial,” said Crosbie. However, the researchers stressed that the surgical option was not for everyone, because it was no an easy choice. “It changes your relationship with food forever, as you’ll be eating smaller meals more frequently, and it is important to remember that surgery can be a hazardous procedure,” said Crosbie. “But for those that choose it, gastric sleeve or bypass surgery can now be seen as a preventative measure for womb cancer.”
Antibiotics can leave the lung vulnerable to flu viruses, leading to significantly worse infections and symptoms, according to a study. The research, published in the journal Cell Reports, discovered that signals from gut bacteria help to maintain a first line of defence in the lining of the lung. When mice with healthy gut bacteria were infected with the flu, around 80 per cent of them survived. However, only a third survived if they were given antibiotics before being infected.

This could be relevant not only in humans but also livestock animals, as many farms around the world use antibiotics prophylactically,” Wack said.

Among the genes switched on by interferon is a mouse gene, Mx1, which is the equivalent of the human MxA gene. This antiviral gene produces proteins that can interfere with influenza virus replication. Although often studied in immune cells, researchers found that microbiota-driven interferon signals also keep antiviral genes in the lung lining active, preventing the virus from gaining a foothold. “We were surprised to discover that the cells lining the lung, rather than immune cells, were responsible for early flu resistance induced by microbiota,” Wack said. “Previous studies have focused on immune cells, but we found that the lining cells are more important for the crucial early stages of infection,” he said. “They are the only place that the virus can multiply, so they are the key battleground in the fight against flu. Gut bacteria send a signal that keeps the cells lining the lung prepared, preventing the virus from multiplying so quickly,” he added. To test whether the protective effect was related to gut bacteria rather than local processes in the lung, the researchers treated mice with antibiotics and then repopulated their gut bacteria through faecal transplant. This restored interferon signalling and associated flu resistance, suggesting that gut bacteria play a crucial role in maintaining defences. “Taken together, our findings show that gut bacteria help to keep non-immune cells elsewhere in the body prepared for attack,” Wack said. “They are better protected from flu because antiviral genes are already switched on when the virus arrives. So when the virus infects a prepared organism, it has almost lost before the battle starts,” he said. “By contrast, without gut bacteria, the antiviral genes won’t come on until the immune response kicks in. This is sometimes too late as the virus has already multiplied many times, so a massive, damaging immune response is inevitable,” he added.
It was a small (slow) step for a tortoise, a giant leap for mankind… When the United States and USSR engaged in a race to the moon in the 1960s, it was one step at a time.Equipment had to be built and tested, experimental flights were performed, and studies of how plant and animal life reacted to the different environment of space were completed.Many animals such as monkeys, dogs and cats went up, but the very first travelers to the moon were reptiles — or to be more specific, Russian Steppe tortoises.Russian tortoise.On September 14, 1968 the Soviet Union launched Zond 5, occupied by not only two Russian Steppe tortoises but insects, mealworms, seeds and plants, and certain types of bacteria. A mock human embedded with radiation sensors was also sent along.The mission was to fly the remotely controlled craft around the moon and return it to Earth.According to NASA, the spacecraft got about twelve hundred miles above the surface and took photographs.The Soviet Union 1969 CPA 3733 stamp (Zond 5)When the craft returned it splashed down into the Indian Ocean and was retrieved by the Russians.The tortoises lost 10% of their body weight weight and had some minor issues with their livers and spleens but remained active and showed no loss of appetite.Hermann’s tortoises are small to medium-sized tortoises from southern Europe.In 1947 an American rocket took a group of fruit flies into space. The rocket went up sixty-eight miles to test radiation theories and came back with all of the fruit flies still healthy.Two dogs and a rabbit were launched into space by the Soviets in 1959 to test the effects of high altitude. When the spacecraft returned to Earth, all of the passengers were alive and fit.NASA Apollo moon landings conspiraciesIn 1970 the Orbiting Frog Otolith was sent into space by NASA to test sustained weightlessness with two bullfrogs aboard. The frogs were attached to electrodes to measure the effect on their inner ears which are much like human ears.The Orbiting Frog Otolith (OFO) spacecrafThe frogs were monitored and stayed in good health adapting to the changes of weightlessness. According to the archives of NASA, the flight lasted six days until the craft’s battery expired. The craft was not recovered.In 1973 two European garden spiders were launched on the second mission to Skylab. One of the spiders built the first web in space. It was spun normally but there were variations of thickness not seen on webs on Earth.Pleurodeles waltl, the species of newt which orbited the Earth on Kosmos 1667.

That particular species of newts are able to grow a new limb to replace one that is severely injured or missing. The newts had undergone surgery to amputate the front limbs and the results came as a bit of a surprise when it was found that the new limbs grew faster in space than if they had been on Earth.The most commonly known animals sent into space were monkeys, dogs and cats. On January 31, 1961, a chimpanzee named Ham was sent into space for NASA’s Project Mercury to measure life support systems in zero gravity.Chimpanzee Ham in his “space suit” before flight in 1961.The chimp was captured from what is now Cameroon in Central Africa at the age of four years and was taught how to work essential controls inside the spacecraft at Holloman Air Force Base in Alamogordo, New Mexico.Ham came home and seemed to be healthy. He died in 1983 at the age of twenty-five at the North Carolina Zoo, and his skeleton was preserved and stored at the National Museum of Health and Medicine of Washington, D.C. The rest of Ham’s remains were buried near the entrance of the International Space Hall of Fame at the Museum of Space History in Alamogordo, New Mexico.A “hand shake” welcome. After his flight on a Mercury-Redstone rocket, chimpanzee Ham is greeted by the commander of the recovery ship, USS Donner (LSD-20).In 1963 France sent a stray female cat with electrodes implanted into her brain into space.

Nearly four decades ago, Australia was shaken by an outlandish case in which two-month-old Azaria Chamberlain mysteriously disappeared. The tragedy unfolded on August 16, 1980, as Lindy and Michael Chamberlain took their three children in Uluru (Ayers Rock), an area in Australia which — besides its iconic monolith stone rock — is noted for the presence of dingoes.The day was supposed to easy-going, having a nice family time out in nature. But only shortly after setting up camp, the trip proved fatal for the Chamberlains. Hearing her baby crying, Lindy went to the tent to check on Azaria.This is an isolated part of a frame from the original video. Over five years after being given a life sentence for murdering her baby Azaria, new evidence is discovered leading to the release of Lindy Chamberlain.

Of Azaria, there was no sign.It must have been in that eerie moment when Lindy Chamberlain uttered her famous phrase that a dingo ate her baby.The media and pop culture were fast to assimilate the tragedy in sensational headlines or works of fiction. The 1988 film A Cry in the Dark in which Meryl Streep takes the role of Lindy and uses “The dingo’s got my baby!” as her grim punchline, assured the phrase was now equally as famous as “the dog ate my homework.”Meryl Streep portrays Florence in “Florence Foster Jenkins.”Photo by Dick Thomas Johnson CC BY 2.0In the meantime, Lindy and Michael Chamberlain were living a horror as they faced accusations of infanticide.The baby’s body was never found in the widespread search carried out in the area, and for some investigators, the story with the dingo seemed dubious.Many fellow Australians did not trust Lindy’s story either. Even though reports of dingoes attacking livestock were well-known, they found it hard to believe the animal would attack a human baby, too.1980 – FILE PHOTO TAKEN IN 1980 – LINDY CHAMBERLAIN’S BABY AZARIA WHO WAS TAKEN BY A DINGO WHILE THE FAMILY WAS ON A HOLIDAY NEAR AYERS ROCK ON 17 AUGUST 1980. (photo by Getty Images)In a follow-up investigation in 1981, traces of blood found in the Chamberlain’s car was taken as evidence of the murder.Prosecutors went on to allege that Lindy Chamberlain slit her daughter’s throat using scissors and, after getting rid of the body with her husband, she used the deceptive dingo story to justify her actions.The trial was vividly followed by Australian media. For the public, it was the most sensational news that a mother had killed her own child even in the absence of a strong motive.At the peak of the scandal, 77 percent of Australians polled said that they thought Lindy Chamberlain was guilty of murder, not any creature from wildlife, according to Time.Disappearance of Azaria Chamberlain (Photo by Russell McPhedran/Fairfax Media/Fairfax Media via Getty Images).The doubts stirred up by the press around Lindy’s story were somewhat murky. One thing was that her husband was a pastor of the Seventh-day Adventist Church, which was scarcely known across Australia at the time. Word quickly spread that the church was an obscure cult and embraced practices such as child sacrifice.The meaning of the baby’s name, Azaria, was also interpreted as “sacrifice in the wilderness.” According to the site huggies.com.au, however, the name means “rose, helped by god, or God helps.”Another thing was how Lindy Chamberlain was perceived when she appeared in court. Never once did the woman publicly yell in anger, she was always well turned out in smart clothes, and the press described her as seeming “cold,” attributes easily associated with someone who might be a cold-blooded killer.Dingo in Exmouth, Western AustraliaLindy was found guilty and sentenced to life in prison. Her husband, charged with being an accomplice to murder, received a lesser punishment. The Chamberlains appealed the decision, but they were denied by the High Court and commenced serving their sentences. Until 1986, when the case had a turning point.A jacket that belonged to Azaria was found in the area of Ayers Rock, the same area containing abundant evidence of dingo dens. The new find substantiated the Chamberlains story of what happened that dreadful August day in 1980.As the sentences for both Lindy and Michael were annulled at this point, a new wave of investigations was initiated. Suddenly it seemed very plausible that the Aussie native dogs were to blame for the girl’s demise, though the cause of death on Azaria’s death certificate was only amended to “unknown.”Azaria Chamberlain’s black clothes, which provoked lots of conspiracy therories, are going on display at the National Museum of Australia in a new exhibition.

SMH Picture by CHRIS LANE (Photo by Fairfax Media/Fairfax Media via Getty Images)It was not until the end of 2010 when the government took up Azaria’s case again after Lindy Chamberlain campaigned to list dingo attack as the official cause of death for her daughter. The case was finally resolved in 2012 when the coroner ultimately ruled exactly that — a dingo was responsible for the murder three decades ago.“The hearing was an ironic repeat of the first coroner’s inquest in 1980-81 when Michael and Lindy Chamberlain had sat together before coroner Dennis Barrett, who agreed to telecast his findings nationwide that a dingo had taken the baby,” wrote the Sydney Morning Herald on the occasion.Australians went on to express their regrets for having wrongfully assumed Lindy Chamberlain was a murderer. Comedians alike apologized for using her phrase in public appearances.Read another story from us: Cages Used to be Put Over Graves to Protect Against Body SnatchersSince Azalia’s case, several other fatal attacks involving the wild dog have been reported on Australian territory, which attests the animal is more than capable to attack even when not provoked.
The Hitchhiker’s Guide To The Galaxy is a British cult sci-fi classic and continues to thrill new generations of fans 40 years after it first appeared on British radio. The Guide originally aired as a radio series in 1978 on BBC Radio Four and went on to spawn a series of novels, TV shows, comic books, video games, and even a feature-length film.This tongue-in-cheek, irreverent sci-fi spoof mixed the themes of travel writing and space exploration to create a devastatingly sharp satire. The story follows the character of Arthur Dent, a British everyman who is lost in space after his home planet (Earth) is destroyed to make way for a hyperspace bypass.Flyer for a 1979 stage production of ‘The Hitchhiker’s Guide to the Galaxy’Dent is saved by his friend and traveling companion Ford Prefect, an alien tasked with updating and writing the eponymous Hitchhiker’s Guide To The Galaxy, a friendly electronic travel guide filled with helpful tips for intergalactic tourists. After teaming up with another surviving human, Trillian, and a paranoid android named Marvin, Dent traverses the galaxy armed with The Guide.AdChoices广告inRead invented by TeadsThe Hitchhiker’s Guide To The Galaxy was the brainchild of author and scriptwriter Douglas Adams. According to Adams himself, the idea behind the story and the title of the book came from an unexpected source.Douglas Adams as a keynote speaker at Internet Security Conference in San Francisco, March 15-17, 2000. Photo by John Johnson CC BY 2.0In 1971, Adams set off on a backpacking trip, hitchhiking across Europe to Turkey. Poor and on a very tight budget, he had stolen a copy of the recently published Hitch-hiker’s Guide To Europe and was using it to find cheap places to stay and eat. According to The Guardian, one night he found himself in Innsbruck, Austria, drunk and, in his own words “frantically depressed.”Related Video: Remembering the Great Stan LeeWhile watching the night sky, Adams was struck by a sudden revelation. According to The Guardian, he later wrote, “When the stars came out I thought that someone ought to write a Hitchhiker’s Guide to the Galaxy because it looked a lot more attractive out there than it did around me.”Artwork depicting the effect of the “Pan-Galactic Gargle Blaster”, an alcoholic beverage invented by Zaphod Beeblebrox which, according to The Guide, is the “Best Drink in Existence”. Photo by Nsh2g2 CC BY 3.0Adams woke the next day in a better mood and continued his journey, hitchhiking all the way to Istanbul. However, the idea stuck, and seven years later he found himself pitching an idea for a radio pilot show under the name The Hitchhiker’s Guide To The Galaxy.Adams was given significant freedom in the early episodes of the show, and the storyline often took unexpected twists and turns depending on his daily whims and ideas. However, he consistently riffed on the formulaic style and themes found in popular travel guides.Arthur Dent finally found the planning application to demolish Earth – on display in a dark cellar “in the bottom of a locked filing cabinet, stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard’”. Photo by Bogdan CC BY-SA 3.0In one long-running gag, Dent is advised to “bring his own towel,” which, according to The Guide, is the most important possession of any self-respecting traveler.The significance of the towel in The Hitchhiker’s Guide To The Galaxy was inspired by another trip taken by Adams as a young man. According to Pan Macmillan, on a holiday to Greece, Adams was the source of constant frustration for his friends and traveling companions because “every morning they’d have to sit around and wait for me because I couldn’t find my blessed towel. I came to feel that someone really together, one who was well organized, would always know where his towel was.”Towel Day 2005 in Innsbruck, Austria.

This festival, marked by people carrying towels with them wherever they go, is particularly celebrated in Innsbruck, the city where the inspiration for the story first struck.Read another story from us: The Writer of Jaws Regretted his Depiction of Sharks and Became an Ocean ActivistIn 1981, Adams recognized the debt he owned to the Hitch-hiker’s Guide To Europe’s Australian author, Ken Welsh. In a letter addressed to Welsh, he explained that he had read the guidebook and that it had inspired his own work, expressing his gratitude and telling him, “your book was really very useful to me.” While it may not have been exactly the outcome that Welsh intended, legions of Adams’ fans are very grateful too.
