The content is provided for information purposes only. In the study, led by George Whitesides of Harvard University, with other coauthors from Harvard, Tufts University, and DARPA, the scientists explain that their system transmits information in the form of coded pulses of light generated entirely by chemical reactions, without electricity. The system is self-powered, with power being generated by combustion. The power density of the system is higher than that of electrochemical batteries, and has the advantage of not discharging over time.As Whitesides explained to PhysOrg.com, the significance of the study is that it “demonstrates direct chemical to binary encoding, and transmission of information at a useful bit rate, without batteries.” The researchers hope that their prototype will one day make it possible to make systems that transmit useful information in circumstances in which electronics and batteries do not work, such as harsh environments and under water.As the scientists explain, the system consists of a strip or fuse of combustible material (nitrocellulose) about 1 mm long. When ignited, a yellow-orange flame moves along the infofuse. To encode information, the scientists patterned the fuse with various metallic salts, which could be done using a desktop inkjet printer or a micropipettor. With their different emission wavelengths, the salts created distinct emission lines in different regions of the electromagnetic spectrum, similar to how the colors of fireworks are made: blue (copper), green (barium), yellow (sodium), red (lithium, strontium, calcium), or near-infrared (potassium, rubidium, cesium). The infofuse, which burns at about 3-4 cm/sec depending on thickness and pattern spacing, is then read by a detector, such as a color CCD camera or fiber optic cable coupled to a spectrometer. The distance between the detector and burning infofuse was typically 2 m, but the detector could still detect a signal up to 30 m away in daylight. Explore further (PhysOrg.com) — While information technology is generally thought to require electrons or photons for transmitting information, scientists have recently demonstrated a third method of transmission: chemical reactions. Based on a flammable “infofuse,” the new system combines information technology and chemistry into a new area the researchers call “infochemistry.” By coding letters of the alphabet using patterns of metallic salts, the scientists transmitted the phrase, “LOOK MOM NO ELECTRICITY” on a single infofuse using the new technique. As the scientists explain, light pulses have several controllable variables that can be used to represent different letters and symbols. In addition to emission wavelength, other variables include pulse duration, time between pulses, and emission intensity. Using combinations of three alkali metals, the researchers demonstrated how to encode 40 different characters by varying some of these parameters. “It needs a flame, but it does not need additional batteries or power, or auxiliary devices, to convert a chemical signal to a digital one,” Whitesides said. “The power needed to generate the light is produced by chemistry directly, not by drawing power from a battery.”Although the current infofuses convert energy into light with only 1% of the efficiency of a battery-operated LED, the infofuses generate 10 times more energy per weight than an alkaline battery generates. In general, integrating information technology and chemistry could have certain advantages, possibly leading to systems that operate beyond binary schemes by using a variety of parameters that allow each information unit to carry more information than a bit. Also, since infochemistry is not bound by the principles of electronics (such as fixed circuitry), but rather the principles of chemistry, new systems could lead to novel architectures.The scientists hope that further improvements to their system could lead to lightweight, portable, self-powered systems that can transmit information and integrate with modern information technologies. Applications could include environmental sensing and transmitting the data optically over a distance. The system could also be used for message transmission in search-and-rescue type applications.More information: “Infochemistry and infofuses for the chemical storage and transmission of coded information.” Samuel W.

Study shows snakes use more force than necessary when climbing trees

first_img © 2014 Phys.org Credit: Western Pacific Tropical Research Center More information: Gripping during climbing of arboreal snakes may be safe but not economical, Biol. Lett. August 2014 vol. 10 no. 8 20140434. Published 20 August 2014 DOI: 10.1098/rsbl.2014.0434AbstractOn the steep surfaces that are common in arboreal environments, many types of animals without claws or adhesive structures must use muscular force to generate sufficient normal force to prevent slipping and climb successfully. Unlike many limbed arboreal animals that have discrete gripping regions on the feet, the elongate bodies of snakes allow for considerable modulation of both the size and orientation of the gripping region. We quantified the gripping forces of snakes climbing a vertical cylinder to determine the extent to which their force production favoured economy or safety. Our sample included four boid species and one colubrid. Nearly all of the gripping forces that we observed for each snake exceeded our estimate of the minimum required, and snakes commonly produced more than three times the normal force required to support their body weight. This suggests that a large safety factor to avoid slipping and falling is more important than locomotor economy. Explore further Citation: Study shows snakes use more force than necessary when climbing trees (2014, August 20) retrieved 18 August 2019 from https://phys.org/news/2014-08-snakes-climbing-trees.html Climbing trees is no easy feat for those that lack claws or other means of attachment—it generally means using brute force which requires some degree of strength. Humans for example, though well muscled in some respects are not well adapted for climbing tress when there are few or no tree limbs to use for assistance—it requires wrapping arms and legs and feet tightly around a trunk and inching upwards. Snakes use very much the same technique, wrapping their bodies around a tree trunk in a coil, then inching their way up by releasing, moving various parts at the appropriate time and then re-gripping. In this new effort, the researchers sought to learn more about how much effort the snakes put into tree climbing.To find out how tightly snakes must grip to climb, the researchers affixed pressure sensors to a pole, which they then covered with tennis racket tape—the combination provided enough friction for adherence by the snakes. They then coaxed five different snakes into climbing the pole, monitoring their progress as they went—four of the snakes were of the boid (boas) species the other a colubrid (a python).In examining their results, the researchers found that all five snakes clung much tighter to the pole than was necessary to prevent slipping or falling—they suggest this is because the snakes placed more importance on clinging to the tree than they did on conserving energy. What’s interesting is that the snakes had a choice—prior research has shown that climbing snakes have very fine control over the amount of squeezing they exert—and thus they are choosing to squeezer harder than they know they need to—and are doing so despite the fact that a fall from a tree in their native habitat would not likely cause injury. This suggests the added pressure is to ensure they don’t fall when predators are around or because they don’t want to have to climb the tree again.center_img Journal information: Biology Letters (Phys.org) —A pair of researchers, one with Siena College in New York, the other with the University of Cincinnati in Ohio, has found that climbing snakes tend to use much more force to hold onto trees than is needed to keep them from sliding back down. In their paper published in the journal Biology Letters, Greg Byrnes and Bruce Jayne describe how they tested snakes climbing in their lab and what they learned as a result.

New Research From Clinical Psychological Science

first_imgMathematically Modeling Emotion Regulation Abnormalities During Psychotic Experiences in SchizophreniaGregory P. Strauss, Farnaz Zamani Esfahlani, Katherine Frost Visser, Elizabeth K. Dickinson, June Gruber, and Hiroki Sayama Confirmatory factor analysis (CFA) is the statistical procedure commonly used to test the validity of different models of posttraumatic stress disorder (PTSD). CFA models allow the identification of symptom dimensions (or factors) that characterize PTSD. In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM–5), PTSD is characterized by four dimensions (e.g., intrusion, avoidance, negative alterations in mood and cognition, and hyperarousal), but since the publication of the DSM–5, CFA models of PTSD have become increasingly multidimensional, identifying six and even seven factors. To clarify why the models of PTSD are becoming increasingly multidimensional, Rasmussen and colleagues examined 23 publications that used CFA and DSM–5symptoms to study PTSD. They found that researchers have been finding support for multidimensionality of PTSD in their CFA analyses mostly because they have not been following basic premises concerning factor identification in CFA. More specifically, the multidimensional models may fit the data, but their factors are underidentified (i.e., composed of fewer than three symptoms) and are correlated with each other, which means they might not be meaningfully distinct. Two positive aspects of the CFA studies examined were that two thirds of them used external data to validate their factors and that most of them relied on large sample sizes. However, the authors suggest the need to improve CFA practices in the PTSD literature, and they offer some practical suggestions about how to do so (e.g., avoid underidentified factors). Thomas and Sharp argue that the dominant approaches to understanding psychological processes, despite helping to elaborate laws between hypothetical psychological constructs and observable data, do not describe links between psychological and biological phenomena or how to integrate them in unified explanations of the psychological constructs. To make up for this shortcoming, they propose the use of mechanistic science. This approach has the goal of explaining how particular psychological phenomena are implemented in living systems, which can be achieved by identifying mechanisms (i.e., structures defined by their component parts, operations, and organization), the functioning of which results in a particular phenomenon. This approach requires that psychological scientists constrain their conceptions of psychological functions to those that might plausibly be implemented by mechanisms in living systems. Thomas and Sharp give the example of biologists applying this approach to move their field from a descriptive to a causal science. They also explain in depth how to apply mechanistic science, giving examples that include a mechanistic explanation of vision processes and a mechanistic framework applied to psychopathology research. The authors suggest that mechanistic science can complement existing research approaches rather than replacing them and that it can facilitate collaboration across fields by providing a common framework for guiding future scientific investigation. Moreover, demonstrating how psychological processes are implemented in biological systems can lead to a better understanding of psychological phenomena and, consequently, more effective interventions in psychopathology. People diagnosed with psychotic disorders often experience symptoms, such as hallucinations or paranoia, that are usually associated with negative emotions that the individuals attempt to manage and regulate. This study examined how individuals with schizophrenia or schizoaffective disorder (SZ) regulate emotions during the presence and absence of psychotic symptoms. For 6 days, four times per day, outpatients with SZ received a message on a mobile device and were required to file the survey immediately. In each survey, participants (a) rated the intensity of their current positive and negative emotions; (b) reported how much they were using emotion regulation strategies; (c) provided information about their current whereabouts, activity, and companions; and (d) reported any psychotic symptoms they could be experiencing. When participants were experiencing psychotic symptoms, they rated their emotions as more negative and reported using emotion-regulation strategies; the type of strategy used depended on the symptom and context. However, emotion regulation at one report time did not result in decreased negative emotion in the next report, especially when negative emotion resulted from auditory hallucinations. During psychotic symptoms, emotions were more densely connected to each other, and denser networks of emotions were more difficult to regulate. These results suggest that emotion regulation failures in SZ result from problems in selecting and implementing regulation strategies but not from identifying the emotions, although denser connections among individual emotions may make it particularly difficult to implement regulation strategies effectively.

Pause a while to play with your imagination

first_imgA solo exhibition Pause and Play, by Puja Kshatriya is all about the inner strength and the complexities and dual nature of relationships. This exhibition is a series comprising of 11 canvases, is an unique interplay of monochromatic figures, emphasising the dual nature and complexities of our relationships. Headless figures, amputated or shifted limbs add an element of surrealism and deconstruction and repetition of images has produced some interesting works. It is almost like looking through a kaleidoscope, where forms join together and then melt away. Also Read – ‘Playing Jojo was emotionally exhausting”Strength and power are often wrongly perceived. Those who appear frail, may in fact be resolutely strong. Wars, as it is has been said, are not always won or lost on the battlefield, but often in the mind. This series called Pause and Play explores the power of mind and how we can we achieve inner strength by detaching ourselves,’ said the artist Puja.’There is no single factor that has inspired me to paint this series. I think, as one  evolves and grows spiritually one realises the power of the mind and how we can we achieve inner strength by detaching ourselves,’ added the artist. Also Read – Leslie doing new comedy special with NetflixHer series Pause and Play emphasises the importance of detachment and the need to build our inner strength. She added, ‘If we can learn to distance ourselves from the immediate surrounding, we can review our perceptions and transform our lives.”I am having an exhibition in Delhi after a hiatus of almost 12 years, my last three solo shows in 2003, 2005 and 2007 being in Mumbai. Since I am from Delhi, this is a special show for me; it’s almost like a homecoming exhibition,’ said the artist. ‘With the objective of creating an interface between Indian contemporary art and its various interpretations, Puja Kshatriya’s work is a vision, an interpretation, allowing the viewer to indulge in their imagination,’ said Ashwini Bahadur, founder of the Artspeaks India.Trying to innovate from the traditional style of painting, Puja uses blade scraping technique, where in two-three layers, oil colours are applied and then blade is used, to bring out the forms. The pressure while scraping is varied, bringing a sculptural effect to the figures.DETAILAt: Shridharani Gallery,Triveni Kala Sangam, 205, Tansen Marg On till: 12 November Timings: 11am to 7pm Phone: 23718833last_img read more

Mythology reinterpreted

first_img“I am a devotee of Goddess Durga and I believe in the feminine power she incorporates,” said Shobha Deepak Singh, producer and director of the ballet act Shree Durga performed at the ongoing Festival of Ballets at Kamani Auditorium on Tuesday. The dance reflected the necessity of emancipation of women in a time when cruelty against women is surpassing all limits. The divine presence of Goddess Durga took over the stage narrating a story from the past. Also Read – ‘Playing Jojo was emotionally exhausting’The act was set in mythological times when the boon, granted by the gods to their devotees, became nuisances and were misused. The dance emphasised upon the importance of bestowing power to women in proportion to men such that a balance is maintained and no evil rises which can cause destruction. Stree Shakti (feminine power) which rose after constant churning of power of the three gods Brahma, Vishnu and Mahesh led the fight against Mahishasur. The whole episode aimed at restoration of balanced power between the genders. Also Read – Leslie doing new comedy special with NetflixIn the next scene the audiences witnessed the rise of Raktabeej, another asur who harasses the gods and whose every drop of blood gives rise to its clone. Kali  (the goddess of destruction) fought with Raktabeej. She drunk the blood of Raktabeej before it fell on the ground.  The whole scene displayed the sheer madness of someone high with power. It was when Shiva intervened by throwing himself on her feet, Kali’s anger could be controlled. The facial expressions of the actor playing Kali, portrayed the rage and anger of the goddess. The performance was magnificent right from the beginning as it started from the contemporary context where common people indulge in worshipping Durga on Durga Puja, a festival of Bengal.The choreography was an amalgamation of various classical dance forms and martial arts technique called Kalaripayattu which is one of the oldest fighting systems in existence. Altogether, it gave graceful body movements to fighting scenes and facial movements for emotions. Other forms of dance like – Bharatnatyam, Chhau, Kathakali and other folk dances were also amalgamated that left the audiences spellbound. “As this is a ballet, we have incorporated ingredients and elements from various dance forms of our country including folk dances,” said Shashidharan Nair, choreographer. The five-day festival that opened on May 8 with the play titled Meera have two more performances Kaalchakra and Kumar Sambhava that will be staged on May 15 and 16 respectively.

The girl behind Who is Kalam

first_imgThe book titled Who is Kalam? may be intriguing but has a heart-warming story behind it. It is the story of a teenaged schoolgirl who posed a tough question to the former President. In turn, she was greeted with an answer that inspired her to become a scientist.It was in 2001, that Sudarkodi Sukumar, a 14-year-old from Tamil Nadu’s Vellore district, sent a question to Kalam in a Tamil monthly for children. She never knew that her question could inspire him so much that he would name a book after it.  Also Read – ‘Playing Jojo was emotionally exhausting’Her question was: “Please rank yourself among the following: Scientist, Tamilian, human being and an Indian.” Kalam’s answer was: “One can find all three in a human being”.In 2003, Sukumar got an invitation to New Delhi for the release of the book Who is Kalam? A Good Human Being, which was dedicated to her. The book by Kalam’s aide R Ramanathan, about the personal side of the scientist-turned-Indian president, was released by the then Prime Minister Atal Bihari Vajpayee.  Also Read – Leslie doing new comedy special with NetflixThe next day, Sukumar, along with her family were called by Kalam in the Rashtrapati Bhavan and the meeting changed her life. “I realised that one has to pursue the passion of one’s life.

Iran deal blocks every pathway for Nweapon

first_imgPresident Barack Obama has strongly defended the landmark Iranian nuclear deal, saying it blocks every pathway for Tehran to acquire nuclear weapons and was in the interest of both the United States and Israel.Addressing the concerns of the Jewish community ahead of a crucial congressional vote next month, Obama in a webcast from the White House said, “this deal blocks every pathway that Iran might take in order to obtain a nuclear weapon.” Because of the stringency of the deal, a vast majority of experts on nuclear proliferation have endorsed this deal, he asserted. Obama on Friday said the world is more or less united, with some exceptions of Israel around the deal.

Beard no longer weird

first_imgToday, among various trends coming in, the resurgence of beard is the most prevalent and pandemic one. Over the ages the tradition of beard has been prevalent and influencing. Although there had been breaks in the fad with the clean shaven look gaining more popularity, recently the beard has made its comeback. Teenagers and adults alike all over the world have begun treating facial hair as a complement to their features. The facial hair trend which gained popularity in the early 2010s continues to grow still showing no signs of decline. Also Read – ‘Playing Jojo was emotionally exhausting’Apart from good looks, beard provides men with cosmetic benefits as well, as it can hide acne or acne scars and strengthen a weak jaw line. So, it is a best substitute for make up for men. Moreover “full beards don’t leave a lot of face to pamper”. Men often use their beards to reflect strength, manliness, self-esteem, ‘swag’ and status. Beards are seemingly attached to just about every twenty-something male face you see. It is believed that a man with a beard generates dominance and lets a woman know that he can be a good protector.  Also Read – Leslie doing new comedy special with NetflixGrowing beard is not an easy task though, it involves patience and perfect grooming. It adds to a man’s personality as well, as it makes him calm and somehow conscious. A man with an endurance of taking care of his beard, grooming it daily is most likely to be a calm person and a good listener. Sporting beard adds to the versatility of looks in men. No matter what, it will always be fashionable to grow a beard. Women too are fond of men with hairy chins, as they are thought to be wise and mature than their clean shaven peers. With the growing concern among men to follow this interesting trend there are certain products available to remove the anxiety, like beard balm which makes the beard look thicker and darker. Beard also lessens the chances of skin aging process by preventing air borne microbes from infecting the skin and provides a lasting look of youth and masculinity. However growing beard needs more hygienic care which means perfect cleansing as beard harbours more germs because facial hair is denser and easily traps dirt and germs. Stating about the increase in the beard trends one can’t step forward without addressing “No-Shave November”, a month long journey during which participants forgo shaving and grooming in order to evoke conversation and raise cancer awareness, a month for all the men to reconcile their love for beards. The “World Beard Day” too has gained popularity, which is celebrated annually on an international level. It is held on the first Saturday of September and is characterised by the happiness of all people being with their beards and with each other. It is about promoting and elevating the global status of the beard. Arya Dev, 22, a DJ by profession sporting a full bearded face stated, “I feel so confident with my beard that I can’t imagine myself without my hairy chin. I think I am obsessed with it.” What if some day he wakes up and finds himself without his beard? He said that he would hide himself for months till his beard grows back.There is a relatively clear pattern of beards coming in and out of fashion. Like the animal inspired beard ‘Goatee’, from Abraham Lincoln to Johnny Depp, this style has found its way in and out of trends. The ‘Full Beard’, which is recently seen attached to Shahid Kapoor in Udta Punjab considerably known as the classic style is among the most tempting ones. ‘Garibaldi Beard’ also known as the statement beard, is best suited to those looking for a slightly more unkempt style. It is a wide and full beard with a rounded bottom and an integrated moustache. Spotted by many including Robert Pattinson and George Clooney, this style offers a vintage and authentic look. ‘Friendly Mutton Chops’ referred as sideburns owned by Hugh Jackman in X-Men seems to be convincing to acquire a different look. ‘Short Stubble’, which can be achieved by growing facial hair for a few days after shaving is one of the most popular and simple sorts of facial hair which seems to be attached to every other male.last_img read more

Loneliness predictive of preclinical Alzheimers disease

first_imgThe constant feeling of being lonely and isolated may be due to the increased amyloid levels in the brain and can be indicative of preclinical Alzheimer’s disease, researchers have found.Loneliness – characterised by subtle feelings of social detachment – may be associated with early brain changes in preclinical Alzheimer’s disease, prior to mild cognitive impairment.The findings showed that higher brain amyloid burden was associated with more frequent feelings of isolation, being left out, and lacking companionship, independent of sociodemographic factors, objective measures of social network, depressive and anxiety symptoms. Also Read – Add new books to your shelf“The study reports a novel association of loneliness and cortical amyloid burden in cognitively normal adults and present evidence for loneliness as a neuropsychiatric symptom relevant to preclinical Alzheimer’s disease,” said Nancy J Donovan, MD, of Brigham and Women’s Hospital and Harvard in Boston. Emotional and behavioural symptoms in cognitively normal older people may be direct manifestations of Alzheimer’s disease (AD) pathophysiology at the preclinical stage, prior to the onset of mild cognitive impairment, the study stated. For the study, the team included 43 women and 36 men with an average age of about 76 years. Out of these, 22 (28 per cent) were carriers of the genetic risk factor apolipoprotein, and 25 (32 per cent) were in the amyloid-positive group based on volume in imaging.  Also Read – Over 2 hours screen time daily will make your kids impulsiveThe participants’ average loneliness score was 5.3 on a scale of 3 to 12. Higher cortical amyloid levels were associated with greater loneliness after controlling for age, sex, genetic risk, socioeconomic status, depression, anxiety and social network. The participants in the amyloid-positive group were 7.5 times more likely to be classified as lonely than non-lonely compared with individuals in the amyloid-negative group. The association between high amyloid levels and loneliness was also stronger in APOE 4 carriers than in non-carriers. “The study will inform new research into the neurobiology of loneliness and other socioemotional changes in late life and may enhance early detection and intervention research in Alzheimer’s disease,” said Donovan.last_img read more

Survey reveals more onehorned rhinos sighted in N Bengal this year

first_imgKolkata: The population of one-horned rhinoceros in Jaldapara and Gorumara in North Bengal has gone up. The findings have come from a recent survey carried out by the department in the two national parks in the state in February.”This is for the first time when apart from direct sighting we have collected the dung of the animal to estimate the population. We have sent the sample for DNA anlaysis in Hyderabad which will be tallied with that of direct-sighting and the census will be released accordingly. The process will take at least six months but we are sure that the numbers will increase,” said state Forest minister Binay Krishna Barman. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseAbout 100 persons, including forest guards, were engaged for the census, along with 18 pet elephants. The earlier census was held in 2015 when 45 rhinos were counted in Gorumara and 214 in Jaldapara. A source in the Forest department said the number of rhinos have gone up to 237 while that of Jaldapara has increased to 53. “The DNA analysis this year will also help us to come up with the male and female population of the animals separately,” a senior official of the state Forest department said. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataThere have been sporadic incidents of poaching of the animal in the forests. However, the state Forest department have taken some significant measures for conservation of the animal which is evident from the population shooting up. The state Forest department has started work for developing the third habitat for rhinoceros at Patlakhawa in North Bengal. The third home for the one-horned rhino is being developed for balancing the rhino population that have increased by both at Jaldapara and Gorumara National Park in North Bengal. The Patlakhawa forest has a large wetland. “We are presently developing the infrastructure that includes boundary of the habitat, grassland improvement watch towers, deployment of security staff, construction of staff quarters , training of staff ,” Barman said. Bengal has the second highest population of rhinoceros after Assam.last_img read more

Cemeteries used to be a Place for Recreation and Fun – Then

first_imgUp until the early 20th century, cemeteries were a popular place to relax, picnic and get together near a loved one’s grave. Almost every major town had a beautiful Victorian cemetery with rolling hills, carefully landscaped grounds, family mausoleums and towering monuments carved into angels, obelisks and other types of statuary. Originally, Americans buried their dead in a churchyard, sometimes in the middle of town. In rural areas, people were often buried on the farm in a piece of land adjacent to the house. With population growth and the many diseases that ran rampant such as cholera and the flu epidemic of the early 20th century, a burial in nothing but a wooden box was not safe.Lower Manhattan cemetery. Photo by Library of CongressAs the cemeteries began to fill up, coffins were placed on top of each other making the ground so weak that storms would wash the dead out of the cemetery and into the road. Burial grounds were relocated or started outside of the town beginning in the 1830s.People usually died at home, and the body was laid out in the parlor where the funeral was held. In England, the body was kept in a bedroom for nearly a week. If a holiday was coming soon, the room would often be decorated to reflect the season. Many Victorians had family pictures taken with the body propped up as if the deceased was alive. These were most common with children.Victorian era post-mortem family portrait of parents with their deceased daughter.Before there were parks and museums in large cities, visiting the new, park-like cemeteries with a picnic lunch was very popular. Children played among the graves, people walked their dogs and families got together for birthdays and other holidays, including the deceased family member in the festivities. No one felt this was in any way disrespectful. Rules were posted as to what could or could not be done, and everyone had a great time.Some headstones were small with only a name and date, but they varied all the way up to fifteen to twenty-foot sculptures with symbolic icons carved into the stone. An anchor with a broken chain symbolizes the end of life; a broken column stands for a life cut short; a dove represents the transport of the deceased’s soul to heaven; candles symbolize the spirit or the soul; a weeping willow tree stands for sorrow; and a hand with a finger pointing upward symbolizes the path to heaven.Mission of Santa Barbara.Organizations’ symbols, such as Masonic, Eastern Star, Woodsmen, Odd Fellows, and Shriners were and still are found on headstones. In the 1800s, most tombstones were made from sandstone which does not hold up well over the years. There was a short fad of using zinc and mostly granite is used now. In the American southwest, simple wood crosses are often used as the weather is more agreeable for maintaining homemade markers.Different cemeteries have different rules. Some allow only flat markers so as not to mar the view, but these have a habit of sinking into the ground if not properly maintained. Within the past few years, granite markers have been lasered to etch a photo onto the stone.There are also custom grave markers made in the shape of motorcycles, sofas, teddy bears, benches, pianos and even automobiles. Large mausoleums hold an entire family within the walls. Mausoleums are popular in flood zone areas, such as New Orleans, keeping the dead above the ground.Cemetery Picnic, Gilliam Cemetery, Graton, CA. Photo by David BerryIn the 21st century, green burials have become popular. The unembalmed deceased is placed in the ground in a simple wooden or cardboard box and is allowed to return to nature.Another new feature is a computerized chip on the headstone that will allow a visitor to look up the deceased and find a biography, pictures and other information.There are companies that will turn cremated ashes into a vinyl record, a diamond or many other strange things. Burials at sea still take place, especially for cremated ashes.Cemeteries are no longer used for recreation, and many have come to regard children playing in a cemetery as disrespectful. Cemeteries have become “creepy” places and are rarely visited except by family members or vandals. Some are abandoned altogether.Read another story from us: The Macabre Story of Sin-EatersThis writer documents cemeteries, especially the older ones.

Scientists Find Lost City of the Monkey God with Rare Animals Thought

first_imgDeep in the Honduras rainforest, a team of scientists has found the archaeological site known as the “Lost City of the Monkey God”– and it is home to several species that were assumed to be extinct as well as many, many other incredible types of birds, reptiles, and mammals. It was once thought that this settlement was a myth dreamed up by conquistadors in the 16th century. There’s long been a rumor of a  pre-Columbian settlement in this region, sometimes known as the “Lost City of the Monkey God” or “La Ciudad Blanca.” Aviator Charles Lindbergh once said he saw it from the sky while he was flying over the area in the 1920s — and many explorers have tried to track down the legendary spot. In 2015, an archaeological site was identified.RAP in Honduras, 2017.The Ciudad del Jaguar (City of the Jaguar) area features a variety of freshwater habitats that support a wide diversity of life, from crabs to otters. Numerous small streams feed into the main river from the surrounding ridges, each creating distinct microhabitats that support unique plant and animal communities.The new team of scientists led by Conservation International’s Rapid Assessment Program (RAP) in coordination with the Government of Honduras arrived to make a survey and found rare species. In one area of the complex, called City of the Jaguar, they discovered at least three species thought to have been extinct. They also found one previously undocumented fish and many other amphibians and mammals close to extinction.AdChoices广告inRead invented by TeadsCamera trap images from Honduras, 2017.A thriving population of white-lipped peccaries, a pig-like species extremely sensitive to deforestation, not found in Central America anymore because they require vast areas of intact forest to survive. When startled or threatened, they produce loud barks and clacking noises with their teeth.“It’s so exciting to get to visit places where literally there’s so few ways to get there,” Trond Larsen, director of Conservation International’s rapid assessment program, told CNN.  “There’s no roads, there’s no logistical infrastructure to access, so you have to helicopter in. And when you do that, you end up visiting places where wildlife tends to be much more abundant.”RAP Honduras, 2017.In a rarely observed event, an Ornate Hawk-Eagle preys upon an endangered Great Green Macaw. Fewer than 2,500 mature Great Green Macaw individuals are thought to be surviving in the wild. Considered to be decreasing due to deforestation, the Ornate Hawk-Eagle is currently listed as Near-Threatened by the IUCN, and is rarely seen in Honduras.The government of Honduras wanted to know what wildlife was living in this undisturbed region and commissioned this extensive survey of the area’s biodiversity, with exciting results. Overall, the team recorded 246 species of butterflies and moths, 30 bats, 57 amphibians and reptiles, alongside many plants, fishes, mammals, and insects.RAP Honduras 2017.The Red-eyed Tree Frog (Agalychnis callidryas) represents one of 22 amphibian species that were documented, included rare and endangered frogs.Located in northeastern Honduras, the Honduran Mosquitia is the largest protected area in the country and constitutes one of the least explored and most pristine areas of lowland rain forest remaining in Central America. Its 865,000 acres supports the highest biodiversity in Honduras “yet the Honduran Mosquitia remains unexplored and poorly known scientifically,” the researchers wrote.The False Tree Coral Snake was rediscovered for Honduras, a species that had not been recorded in the country or for northern Central America since 1965. Eight of the species found were documented for the first time in the core of the Reserva del Hombre y la Biosfera del Río Plátano and several more are threatened, rare and poorly documented for Honduras.RAP in Honduras, 2017.The false tree coral snake (Rhinobothryum bovallii), discovered on the expedition, was believed to be extinct in Honduras since 1965.Forty small mammal species were identified, representing 30 bat species and 10 rodent species. Of the bats detected, one species is a new record for Honduras, three others have very restricted distributions and few previous records for the country, and another — the Pale-faced Bat — has not been reported in Honduras in more than 75 years. Larsen told CNN  that the creatures that live in the area aren’t used to human interaction, which allowed for some incredible moments of interaction.RAP in Honduras, 2017.The Pale-faced Bat (Phylloderma stenops) was rediscovered during this survey after more than 75 years since it was last documented in Honduras in 1942.“Large groups of monkeys, for example, hang out and try to figure out what you are and what’s going on, there’s an opportunity to see tremendous amounts of wildlife,” he says.RAP in Honduras, 2017.A venomous Eyelash Viper (Bothriechis schlegelii) uses its tongue to ‘smell’ thesurroundings.The salamander Bolitoglossa mexicana is an excellent climber and is usually found in trees and shrubs.While commonly seen in much of North America, salamanders are rare in the Neotropics.RAP in Honduras, 2017.Check out that long tail!
