Citation: Frog embryos associate the smell of predators with danger (2009, November 3) retrieved 18 August 2019 from https://phys.org/news/2009-11-frog-embryos-associate-predators-danger.html The aim of the experiments was to find out if woodfrog (Rana sylvatica) embryos could learn to associate the odor of injured tadpoles with that of their predator, and if they could discriminate between different levels of threat. They also aimed to find out if the time of day would be a factor.In the study, woodfrog egg masses were put into water containing the odor of tiger salamanders (Ambystoma tigrinum) and various concentrations of “injured tadpole” odor between the hours of 1500 and 1700 for five consecutive days. They were then raised for nine days after hatching.The scientists, Dr. Maud Ferarri, from the University of California at Davis, and Douglas Chivers from the University of Saskatchewan, created the olfactory cues by using water previously occupied by a tiger salamander, and water containing varying concentrations of crushed tadpoles. Both chemical cues were added to the water surrounding the frog egg masses.When the eggs hatched, the scientists tested the responses of the tadpoles by placing them in fresh water and measuring how much they moved. They then added water containing the salamander odor, and measured their movements again. They checked the responses at different times. The results revealed that the embryos had learned to associate the predator’s odor with danger.The results ranged from tadpoles swimming normally to freezing for several minutes. Tadpoles that had been exposed as embryos to higher concentrations of injured tadpole odor froze for the longest time, which the scientists say shows they had learned to associate the salamander odor with danger. (Freezing is a common behavior when faced with a threat.) Responses were stronger between 1500 and 1700 hours than they were if the tadpoles were exposed to the odor either earlier or later. The researchers said this type of learning has been found previously in larval amphibians, mosquitoes and fish, but had not been seen in embryos until now.Dr. Ferarri said the embryos presumably “smell” the cues in the water surrounding the eggs. She also said that learning to detect predators at such an early stage makes evolutionary sense and there must be selection for learning to detect predators in this way as it is often the only way they have to recognize them.The findings of the study were published in the Behavioral Ecology and Sociobiology journal.More information: The ghost of predation future: threat-sensitive and temporal assessment of risk by embryonic woodfrogs, Behavioral Ecology and Sociobiology, DOI:10.1007/s00265-009-0870-y© 2009 PhysOrg.com Explore further Time of Day Tempers Tadpoles’ Response to Predators This document is subject to copyright.

Increase in acidity may not be harmful to coral reefs after all

first_img © 2015 Phys.org More information: K. L. Yeakel et al. Shifts in coral reef biogeochemistry and resulting acidification linked to offshore productivity, Proceedings of the National Academy of Sciences (2015). DOI: 10.1073/pnas.1507021112AbstractOceanic uptake of anthropogenic carbon dioxide (CO2) has acidified open-ocean surface waters by 0.1 pH units since preindustrial times. Despite unequivocal evidence of ocean acidification (OA) via open-ocean measurements for the past several decades, it has yet to be documented in near-shore and coral reef environments. A lack of long-term measurements from these environments restricts our understanding of the natural variability and controls of seawater CO2-carbonate chemistry and biogeochemistry, which is essential to make accurate predictions on the effects of future OA on coral reefs. Here, in a 5-y study of the Bermuda coral reef, we show evidence that variations in reef biogeochemical processes drive interannual changes in seawater pH and Ωaragonite that are partly controlled by offshore processes. Rapid acidification events driven by shifts toward increasing net calcification and net heterotrophy were observed during the summers of 2010 and 2011, with the frequency and extent of such events corresponding to increased offshore productivity. These events also coincided with a negative winter North Atlantic Oscillation (NAO) index, which historically has been associated with extensive offshore mixing and greater primary productivity at the Bermuda Atlantic Time-series Study (BATS) site. Our results reveal that coral reefs undergo natural interannual events of rapid acidification due to shifts in reef biogeochemical processes that may be linked to offshore productivity and ultimately controlled by larger-scale climatic and oceanographic processes. To better understand what might happen with coral reefs if more carbon dioxide makes its way into the oceans due to an increase of the gas in the atmosphere caused by human emissions, the researchers set up monitoring devices along a coral reef offshore from Bermuda—information from the sensors was monitored for five years (2007 to 2012). The team also had access to data from an ocean chemistry monitoring station approximately 80 kilometers from their study site. The combined data offered a unique perspective on coral activity.In studying the data, the researchers noticed that spikes of phytoplankton blooms occurred during 2010 and again in 2011—those blooms made their way to the coral reef offering more food than normal for the coral. The coral responded by growing which caused them to pull more alkaline carbonate from the surrounding water, making it more acidic. Eating more also resulted in the corals emitting more carbon dioxide into the water. The result was a big increase in acidity—to levels higher than have been predicted for the future due to human emissions—yet, the coral continued to flourish.These observations contrast sharply with the prevailing view that an increase in acidity is harmful to coral—leading to death if it goes too far. But the levels seen by the researchers with this new effort suggest that is not the case at all, and therefore muddles theories regarding the impact on the oceans of higher levels of carbon dioxide and warmer temperatures. Another team with Western Australia noted that the results found by this new team appeared to agree with those of a small study they conducted where they put boxes around some coral and piped in carbon dioxide, to no detrimental effect.

Pulp friction

first_imgThe imminent ‘pulping’ of Wendy Doniger’s The Hindus: An Alternative History sounds an ominous bell. It is really two things at once: one, the relentless political pressure rising from the far-right religious groups, whether they be Hindu, Islamic or Christian; and the other, the shrinking of liberal space via a) censorship and b) self-censorship. The decision to opt for an out-of-court settlement and look for a quiet exit by Penguin, in this light, is no less criminal than Dinanath Batra’s feeling offended by Doniger’s innovative interpretation of Hinduism, particularly by its uncovering of neglected and subaltern histories – those of women, Dalits, Tantric yogis and other practitioners of pleasure and pain that go, strictly speaking, against the ‘bourgeoisie’ Vendantic tradition, favouring all the entrenched divisions and tiers within the religion. So while we feel embarrassed and offended by Batra’s lawsuit that describes Doniger’s ‘factual inaccuracies’, we should feel a million times more let down, and indeed we do, by Penguin India’s pusillanimous stand, its supine succumbing to a little pressure from a tiny group affiliated with the RSS. Also Read – ‘Playing Jojo was emotionally exhausting’Doniger’s tome is not alone in this tragedy of collective ineffectuality. We had A K Ramanujan’s stellar essay Three Hundred Ramayanas scrapped from the Delhi University’s MA English curriculum only three years back. Other works of historical reinterpretation, say Joseph Lelyveld’s Great Soul, based on M K Gandhi’s stint in South Africa, was dubbed unreadable and insulting for its frank explorations of sexuality. We have, of course, the epic case of book banning and burning in The Satanic Verses, the hounding flames of which still reach for the NYC-dwelling Salman Rushdie, making his India tours a matter of great political and public consternation. We also have Taslima Nasreen, whose books keep facing the axe at the same pace at which she pens them, choosing still to go with the gut rather than opting for safer thematic havens. Among artists, we have the grand catastrophe and historical blunder in the maestro, the late M F Hussain, picking exile in Qatar over the ‘creative chaos’ of India as a result of Shiv Sena’s constant vandalisation of his works, his nude Saraswatis and Mother Indias. Also Read – Leslie doing new comedy special with NetflixNo matter how we wish to look at it – whether as a grand dance of democracy which throws to the surface the obscene but often sidelined voices of the neo-natives, the hardline cultural nationalists, the patriarchal patriots, mostly all easily offended, or as a muzzling of truly liberal and radical voices, not just those dressed in seminar English and political correctness of the day, but those digging deep and excavating lost or buried tropes, shedding new light on the subterranean tunnels of history, politics and literature – there’s little joy in seeing a book waiting for the gallows. Much like capital punishment, pulping or burning of books reeks of an extreme punitive approach to dissent, to difference and to the other. It’s uncomfortable with non-conformity; hence perennially threatened. It’s rarely the exact occasion that ensues this angry bird’s hawkish ire – it’s more a mouldy and partisan convenience, whether of relevance or reiteration, that sets off the triggers, resulting in violence, intellectual, physical and cultural. It is in fact the same state-society complex that punishes people and ostracises them for thinking and expressing differently, say in their choice of sexual partners, or in their interlacing of words with loaded sexuality, particularly of the dissident variety, also goes for the theory of banishment – of ideas, of people, of lives. Hence, whether Doniger’s book is an erudite work of scholarly brilliance or a puerile mass of unsubstantiated conjectures is not the question. The real question is: why can’t Doniger’s book exist, be read, shared and critiqued, stirring, as the Chicago University-based ‘Indologist’ hoped, ‘creative controversy’? Why must debate be sacrificed at the altar of sameness, or interpretations that have ossified and exploited millions for thousands of years thwart ones that are new and contentious?  And, in this context, why can’t a publisher, one of the oldest and biggest, with liberal pretensions and self-aggrandising tone and tenor, also a global shark really with the latest merger with Random House, stand up to a small, literally insignificant tributary of the RSS stream?These are strange times. If world cities and mega malls have no room for libraries and if we run out of reading material, if we stop ourselves from coming out and reclaiming the streets, the bedrooms, the pages, the ink, the mind and the bodies, what good would that be? Perhaps, the mantra ‘publish or perish’ has a new meaning now.Is the Chicken listening?last_img read more

Govt to set up centre of excellence for agriculture

first_imgKolkata: The Bengal government is likely to set up a centre of excellence (COE) for agriculture and horticulture at Chinsurah in Hoogly district by the end of this year, department of Food Processing Industries and Horticulture secretary Nandini Chakravorty said on Tuesday.While addressing a seminar organised by the Merchants’ Chamber of Commerce and Industry in the city about the development of food processing industries and horticulture in West Bengal, Chakravorty said: “Agriculture is very technology-intensive and so there is a dire need to bring in new techniques and technologies. We have pondering for a while to set up a centre of excellence in Bengal. Earlier, it had not received approval from the government of India but now we are bringing the centre of excellence under a different scheme with the Israelis and the setup should be completed by 2019”.

Immediately, Rajjak was detained and grilled. During interrogation he admitted that the powder was a derivative of cocaine identified as Methaqualone which is being used as substitute of cocaine in many places outside India. Rajjak was arrested and later, cops came to know that the Methaqualone was destined for Hong Kong. According to the police, 60 bangles were found inside which Methaqualone was concealed. Sleuths also came to know that Rajjak with a few others were running the racket for a long time. They used to send the Methaqualone concealed in the cosmetic jewellery which are very popular in Hong Kong. The consignments were being sent via courier services. The seized Methaqualone is worth Rs 50 lakh. Each one gram of the narcotics substance is worth Rs 8,000 approximately. Rajjak is being interrogated to nab other racketeers.last_img read more

Childhood abuse worsens depression in adulthood

first_imgFacing trauma in childhood can significantly change the structure of the brain, which may result in severe depression which could even be recurrent in adulthood, say researchers. The results from MRI scan images suggest that both childhood maltreatment and recurring depression are associated with similar reductions in the surface area of the insular cortex, part of the brain that regulates emotion and self-awareness. This reduction could make a future relapse more likely, said the study, published in The Lancet Psychiatry journal, which found childhood maltreatment one of the strongest risk factors for major depression in adulthood. Also Read – Add new books to your shelf”Given the impact of the insular cortex on brain functions such as emotional awareness, it’s possible that the changes we saw make patients less responsive to conventional treatments,” said lead researcher Nils Opel from the University of Munster in Germany. The study included 110 patients aged 18 to 60 years. Of the 75 patients who experienced a relapse, 48 had experienced one additional episode, seven reported two episodes, and six experienced three episodes. Fourteen had a remission period of less than two months and could therefore be regarded as having chronic depression. The findings are to develop or improve risk-adapted interventions for people susceptible to a worse long-term clinical outcome. Future research should therefore explore how the findings could be translated into care and treatment that could improve patient outcomes.last_img read more

Fake news can be countered by identifying source credibility

first_imgEstablishing the credibility of the source of information can help combat the growing menace of fake news, a study has found. Misinformation or fake news is a threat to democratic institutions and false information can have far-reaching effects, researchers said. The study, published in Proceedings of the National Academy of Sciences, provides a roadmap for dealing with fake news. People’s beliefs about the source of information affects how they take in that information, even at the level of their automatic responses, researchers found. Also Read – Add new books to your shelfThey also found that new information can modify or even undo existing impressions caused by fake news. “We wanted to know whether offering information about the source of news matters for people’s gut-level, automatic reactions,” said Melissa Ferguson, a professor at Cornell University in the US. “Does knowing that something is fake have lingering pernicious effects that can later shape and influence our thoughts and behaviour toward the person? Our studies suggest that establishing credibility for news sources is the right policy to combat fake news,” Ferguson said in a statement. Also Read – Over 2 hours screen time daily will make your kids impulsiveResearchers conducted seven experiments with more than 3,100 participants to assess how the truth value of new information about others affected both their reported feelings and their gut-level, automatic reactions. The experiments ranged from using video games and narratives of intergroup conflicts to studies featuring an individual named Kevin. Researchers used Kevin to assess how attitudes toward him changed depending on what information was provided. In one experiment, Kevin was depicted positively. Participants were then told something disturbing, including that he had been arrested for abusing his wife. Researchers found that when news about the arrest came from police reports, gut-level attitudes toward Kevin immediately became more negative. However, when that information was attributed to a friend of Kevin’s ex-girlfriend, participants retained their positive attitude toward Kevin. “In other words, whether participants thought this new information was true determined even their automatic feelings,” the researchers said.last_img read more

A radical feminist shot Andy Warhol claiming that he controlled her life

first_imgFew artists have had more influence on modern pop culture than Andy Warhol. The shy, quiet man was one of the most popular artists in the 1960s due to his irreverence towards art convention and his ability to promote other artists, who were known as Warhol Superstars.Indeed, he would influence much of the art world with his art, such as the famous Campbell’s Soup Cans which simply portrayed soup cans.Some were delighted by his work, others were infuriated by what they believed to be the cheapening of the art world, but all were mystified by the man’s ability to rise to the top of the pop art world.Andy Warhol, between 1966 and 1977. Photo by Jack Mitchell CC BY-SA 4.0Warhol was no stranger to admiration and his studio, known as the Factory, was where many a celebrity and artist would congregate and socialize. Art was produced, films were made and relationships grew and blossomed between Warhol and the regulars who would attend the Factory.The productions made by the Factory were extremely counter-cultural at the time. Andy Warhol was an openly gay man and many of his film productions would include elements of brazen sexuality that would shock the conservatively minded individual.Andy Warhol (right) and Ulli Lommel on the set of Cocaine Cowboys. Photo by Hollywood House of Horror CC BY SA 3.0It was this reputation for creating shocking and offensive art that would lead a woman by the name of Valerie Jean Solanas to seek out his assistance with the production of a play. This play, titled “Up Your Ass,” was by all accounts a terrible and vulgar story that had little appeal to anyone.Valerie, upon meeting Warhol outside of the Factory one morning, gave him the script and asked for him to read it, in the hopes that he would agree to produce the piece. Warhol accepted the script but didn’t particularly care for the play itself.Actress Valeria Solanos. Photo by Bettmann/Getty ImagesThe themes of the play greatly reflected Valerie’s personal beliefs. As a radical feminist, she advocated the ultimate elimination of men in the world, believing that society was fundamentally broken and only the rise of a female government and the execution of all men would be the cure.This was reflected in the book she began writing known as the SCUM Manifesto, SCUM was short for the Society of Cutting Up Men. When Valerie Solanas contacted Warhol again, asking if he had read her play and was willing to produce it, he told her that it had been lost somehow.Warhol (left) and Tennessee Williams (right) talking on the SS France, 1967.She was outraged at this news and demanded that she be paid for the work. Warhol managed to smooth things over by offering her a part in his movie, I, a Man, with the pay of $25. She accepted and played a bit role in the production.This only appeased her for a short period of time. As she was working on the SCUM Manifesto, she made friends with the founder of Olympia Press, Maurice Girodias.An ad placed by Solanas in The Village Voice, April 27, 1967.In their conversations, Girodias offered Valerie $500 for her next book and other writings, which she accepted. They signed a contract, but the wording of the language caused Valerie to begin to worry about the life rights to all of her work. For some reason, she began to believe that Girodias would own the rights to all of the works that she would ever create. Worse, Girodias was a close friend of Andy Warhol’s, which led her to one conclusion: Andy was trying to steal her work.Portrait of the American artist Andy Warhol at his exhibition dedicated to Black transvestites in the U.S. Ferrara, November 1975.The idea might seem absurd, but Valerie Solanas connected the disappearance of her script to the new contract that she had signed. In her mind, Andy Warhol was out to take all of her work and leave her with nothing. This prompted her to go out and purchase a gun. She knew that there was only one way to protect her work, and that was to kill Andy Warhol.Warhol portraits set for up £22 million at auctionShe arrived at The Factory on June 3, 1968, looking for Andy. She was turned away, but due to her persistence, she was able to get into the building when Andy finally arrived around 2:00 pm.Not suspecting a thing, Warhol was congenial towards her, complimenting her. His associate, the film director Paul Morrisey, tried to get her to leave, but she wouldn’t have it.When Andy Warhol was taking a phone call, she drew her gun and fired three times at him, with one shot dropping him down hard.Detective Frederick Stepat and policewoman McCarthy with Valerie Solanas. Photo by Frank Russo/NY Daily News Archive via Getty ImagesAfter she shot Warhol, she shot an art critic and tried to kill Warhol’s manager, but her gun jammed. Then she left, satisfied that her opponent, the man scheming to steal her art was dead. But Warhol survived and was rushed into surgery. His lungs, liver, and spleen had been heavily damaged. Thanks to the surgeon’s efforts, after five hours Warhol was saved, but he would have to wear a surgical corset for the rest of his life.As for Valerie Solanas, she turned herself in, believing that she had been justified in her actions. In her testimonies, she maintained that she was only working to protect herself from Warhol’s influence and claimed that he had total control of her life. It didn’t take long for the court to rule that she suffered from paranoid schizophrenia and she was placed in a mental hospital for treatment.Andy Warhol tombstone, St. John the Baptist Byzantine Catholic Cemetery, Bethel Park, PA.Warhol survived and continued with making his art, but the attempt on his life profoundly changed the way that he saw the world. Security was beefed up at the Factory and he began to focus less on shocking the world and more on entrepreneurship, still achieving great success in the art world. He would die at the age of 58 after a gallbladder surgery.Read another story from us: Factory girl to blond bombshell: the life of Norma Jeane before she became Marilyn MonroeSome believe, perhaps rightly so, that the injuries he had incurred from the gunshot led to the complications in what should have been a routine surgery.Andrew Pourciaux is a novelist hailing from sunny Sarasota, Florida, where he spends the majority of his time writing and podcasting.last_img read more

Home Depot Says About 53 Million Email Addresses Stolen in Breach

first_imgNovember 7, 2014 Register Now » Home Depot Inc, the world’s largest home improvement chain, said hackers stole about 53 million email addresses in addition to customer data for 56 million payment cards previously disclosed by the retailer.The company, which confirmed the breach in September, said the files that contained the email addresses did not include passwords, payment card information or other sensitive personal information.Home Depot, which had estimated that the theft would cost about $62 million, was one of a string of U.S. retailers attacked by hackers over the past year.Criminals used a third-party vendor’s user name and password to enter the perimeter of its network, Home Depot said in a statement on Thursday.The hackers then acquired “elevated rights” that allowed them to navigate parts of Home Depot’s network and to deploy unique, custom-built malware on its self-checkout systems in the U.S. and Canada, according to the company.Home Depot said the stolen credentials did not alone provide direct access to the company’s point-of-sale devices.Since September, the company has implemented enhanced encryption of payment data in all U.S. stores and said the rollout to Canadian stores will be completed by early 2015.This, however, was “really lipstick on a pig” and the proper solution was to add chip and PIN, or EMV technology, to U.S. credit cards, said David Campbell, chief security officer at SendGrid, a cloud-based email delivery service.Home Depot said it was already rolling out the EMV technology.The company reaffirmed its 2014 sales growth forecast of about 4.8 percent and earnings per share forecast of $4.54.The forecast includes estimates for the cost to investigate the data breach, provide credit monitoring services to its customers as well as legal fees, the company said.”I think the big takeaway was that they are able to maintain their sales guidance for the full year, which means people are still showing up at the stores, still spending..” Joseph Feldman, analyst at Telsey Advisory Group, told Reuters.The company maintained that it has not yet estimated the impact of “probable losses” related to the breach.”Those costs may have a material adverse effect on The Home Depot’s financial results in the fourth quarter of fiscal 2014 and/or future periods,” the company said.Home Depot shares closed up 1.6 percent at $97.29 per share on Thursday on the New York Stock Exchange.Target Corp’s unprecedented breach saw hackers steal at least 40 million payment card numbers and 70 million other pieces of customer data in 2013.(Reporting by Devika Krishna Kumar in Bangalore; Editing by Rodney Joyce, Joyjeet Das and Cynthia Osterman) This story originally appeared on Reuters Growing a business sometimes requires thinking outside the box.
