After running simulations in their lab, the researchers found that neutron stars with lumpy “pasta-like” surfaces would slow to a certain point then stop slowing with periods remaining constant at near to 12 seconds.

DNA testing solves mystery of Titanic survivor claim

first_img Trove of 200,000 Titanic records goes online © 2014 Phys.org (Phys.org) —DNA testing has proven that Helen Kramer was not Loraine Allison, a two year old child who was believed to have died when the infamous ocean liner Titanic sank April 15, 1912. Ms. Kramer died in 1982—she rose to fame after claiming on a radio program in 1940 that that she was in fact the long lost toddler. Explore further Brave Nurse and the Babe She Saved: Alice Cleaver with Trevor Allison, survivors of the sinking of the RMS Titanic after disembarking from the RMS Carpathia Kramer apparently hung on to her claim for her entire life, thus it’s not clear if she herself perpetuated the fraud or if it was foisted onto her as a child. She claimed that she had been put aboard a life raft by none other than Thomas Andrews—the man that had designed the ill-fated liner. Loraine Allison and her mother were both believed lost when the ship sank though neither body was ever recovered. The child’s father also died when the ship sank but his body was eventually found. Kramer insisted that she’d been taken in and raised by a man, a fellow passenger in the lifeboat, who explained to her sometime later that she was the missing child.Adding to the sensationalism of the story was Debrina Woods, Helen Kramer’s granddaughter who claimed to have physical evidence that her grandmother was who she claimed to be and more recently said she was writing a book about the whole story. That was enough apparently for a group of Titanic aficionados to get together and create what they called the “Loraine Allison Identification Project.” That resulted in funding to undertake DNA testing of members of both of the involved families—a great niece of Loraine’s mother and Woods’ half-sister—the results show absolutely no connection between the two families.The story of the missing toddler took on more drama when it was revealed that she was believed to be the only non-adult housed in the first class section of the boat to have died when the ship sank. Various reports from survivors suggest the family remained on the ship looking for little Loraine’s younger brother, who unbeknownst to them, had been placed in a lifeboat by a servant. He was the only member of the family believed to have survived the sinking. This document is subject to copyright.

German researcher warns climate scientists to not kowtow to politicians

first_imgCredit: Alfred Palmer/Wikipedia (Phys.org)—Oliver Geden, a researcher with the German Institute for International and Security Affairs has published a Comment piece in the journal Nature, warning of the dire consequences of climate scientists bowing to pressure exerted by politicians and government officials. His admonitions come just a month before the UN is to meet to discuss and report on the progress of the 2C goal. Citation: German researcher warns climate scientists to not kowtow to politicians (2015, May 7) retrieved 18 August 2019 from https://phys.org/news/2015-05-german-climate-scientists-kowtow-politicians.html This document is subject to copyright.

More information: Policy: Climate advisers must maintain integrity, www.nature.com/news/policy-cli … in-integrity-1.17468 Journal information: Naturecenter_img © 2015 Phys.org The 2C goal aka the Copenhagen Agreement of 2009, refers to an agreement and signing of a document by multiple countries promising to attempt to prevent global temperatures from rising 2 °C—a threshold that some suggest was arbitrary and others derided as being far too reckless. Countries most likely to be the most heavily impacted by such a rise, such as small island nations worried about ocean’s rising, pleaded for a lower standard. In his comment piece, Geden suggests that some climate scientists are stepping outside their domain and into the domain of politics, and the results could be disastrous.One particularly galling example, Geden notes is the very idea of “negative emissions” where carbon emissions continue to pour into the atmosphere for a number of years, in the hope that some new technology or plan will come along that will offer a way of actually taking out more carbon than we add. Such a plan (BECCS: bioenergy) now calls for dedicating a piece of land the size of India to serve as a dump of sorts. The plan, dreamed up by some climate scientists Geden notes, has no basis in science. It is not known if such an approach would work, or if removing carbon after the fact would save the planet from the impact of years of high carbon levels.Talks next month at the UN, which are supposed to lead to another meeting in December in Paris, and perhaps the signing of another document, Geden suggests, should not include politicized science offered by researchers who have had to make a choice between offering watered down versions of reality, or being ignored. He very nearly begs climate scientists reading his words to consider whether they want to inform, or to be a part of the political process—such scientists, he cautions, and the scientific community as a whole needs to defend its independence from dominance or interference by governments, politicians and businesses with their own agendas.

Comet C2016 R2 PanSTARRS is rich in carbon monoxide and depleted in

first_imgC/2016 R2 (Pan-STARRS) is a comet abundant in carbon monoxide and lacking hydrogen cyanide, according to a new study conducted by researchers from the University of South Florida (USF) in Tampa, Florida.

We obtained spectra and maps of the CO J=2-1 rotational line at 230 GHz between 2017 December and 2018 January. We calculated an average production rate of Q(CO)=(4.6+/-0.4)x1028 mol s−1 at r ~2.9 au and delta ~2.1 au. The CO line is thin FWHM ~ 0.8 km s−1 with a slight blue-shift ~ -0.1 km s−1 from the ephemeris velocity, and we derive a gas expansion velocity of Vexp = 0.50+/-0.15 km s−1. This comet produced approximately half the CO that comet C/1995 O1 (Hale-Bopp) did at 3 au. If CO production scales with nucleus surface area, then the radius need not exceed ~15 km. The spectra and mapping data are consistent with CO arising from a combination of a sunward-side active area and an isotropic source. For HCN, we calculated a 3-sigma upper limit production rate of Q(HCN) < 8x1024 molecules s−1, which corresponds to an extraordinarily high abundance ratio limit of Q(CO)/Q(HCN) > 5000. We inferred a production rate of molecular nitrogen of Q(N2) ~2.8×1027 molecules s−1 using our CO data and the reported N2/CO column density ratio (Cochran & MacKay 2018a,b). The comet does not show the typical nitrogen depletion seen in comets, and the CO-rich, N2-rich and HCN-depleted values are consistent with formation in a cold environment of T < 50 K that may have provided significant N2 shielding. The first detection of CO emission in C/2016 R2 on UT 2017 Dec 22, when the comet was at r = 2.9 and ∆ = 2.1 AU. Credit: Wierzchos and Womack, 2018. Explore further Discovered on September 7, 2016, C/2016 R2 (Pan-STARRS) is an Oort Cloud comet orbiting the sun at a distance of about 740 AU, approximately every 20,000 years, on a highly eccentric orbit. The comet is known to have a deep-blue-colored coma and a very complex ion tail. The Oort Cloud is perceived by astronomers as a reserve of cometary nuclei that contain ices dating back to the early solar system. Therefore, studying such comets as C/2016 R2 could provide important hints about the origin and formation of planets and other objects orbiting the sun.C/2016 R2 was recently observed by USF's Kacper Wierzchos and Maria Womack. For their observations, conducted in December 2017 and January 2018, the astronomers employed the 10-m Submillimeter Telescope at the Arizona Radio Observatory. The observational campaign was focused on the search for carbon monoxide (CO) and hydrogen cyanide (HCN) emission in the comet."We used the Arizona Radio Observatory 10-m Submillimeter Telescope in order to search for CO J=2-1 (at 230.53799 GHz) and HCN J=3-2 (at 265.88643 GHz) emission in comet C/2016 R2 during 2017 December - 2018 January when its heliocentric and geocentric distances were r ~ 2.9 au and ∆ ~ 2.1 au, respectively," the paper reads.As a result of the observations, the researchers detected neutral carbon monoxide emission in this comet for the first time. They found that the production rate of CO is very high and when compared to other comets, this rate is half that of C/1995 O1 Hale-Bopp at this same distance from the sun. Hence, C/2016 R2 is described by Wierzchos and Womack as a CO-rich comet in which carbon monoxide emission is assumed to be the primary driver of activity.However, the researchers found that the production rate of hydrogen cyanide is much lower – about 100 times lower than observed for C/1995 O1 Hale-Bopp at the same distance. The researchers noted that the calculated CO/HCN production rate ratio of over 5,000 indicate an unusual chemical composition of C/2016 R2 that is difficult to understand in terms of typical comet compositions.To better understand the peculiarity of C/2016 R2 the astronomers measured the production rate of molecular nitrogen (N2). They found that this comet is also N2-rich, not showing the typical nitrogen depletion seen in comets.According to the authors of the paper, the calculated values underline the oddity of C/2016 R2. "R2's coma composition is clearly very different from other comets observed thus far, both in the high N2 abundance, and significant decrease in other typically abundant molecules, such as HCN," the researchers concluded.last_img read more

SHG dept bats for schemes for Kalimpong devp boards

first_imgKolkata: The Self-Help Group (SHG) department is preparing a blueprint to ensure that various development boards under the newly crafted Kalimpong district can avail the facilities of various schemes and benefits, which the department has been undertaking under the leadership of Chief Minister Mamata Banerjee.On his four-day visit to North Bengal recently, state minister for Consumer Affairs and Self-Help Group Sadhan Pande held a meeting with the top representatives of the development boards in Kalimpong and apprised them of the various schemes of the department.”The minister has directed the chairmans of the boards to submit a proposal highlighting certain areas in which the department can provide them training and create infrastructure for any production unit if required. They have to forward their proposal through the District Magistrate of Kalimpong, who along with the senior government officials at the district level were present in the meeting,” a senior official of West Bengal Swarojgar Corporation Ltd (WBSCL) said. Some of these development boards have informed the ministers that they have already formed Self-Help Groups.The minister visited a number of small units that have been doing activities like floriculture, horticulture, orchid plantation and urged them to form Self-Help Groups so that they too can avail the fruits of benefits. “Our basic aim is to set up micro, projects like poultry shed, goatery shed, poly green house, etc. for sustainable development and livelihood of the SHG members,” Self-Help Group minister Sadhan Pande said.Kalimpong, the 21st district in the state, was formed on February 14 2017, after splitting from Darjeeling. It consists of the Kalimpong Municipality and three community development blocks: Kalimpong I, Kalimpong II and Gorubathan. It may be mentioned that WBSCL under the SHG department has been providing training to the SHG members on various fields like tailoring, goatery, poultry, floriculture, hospitality management, handicrafts, jute crafts, food products, computer application, mushroom cultivation, beautician, etc.”We are also organising melas/fairs for marketing of SHG products and providing interest subsidy for these members by creating bank linkage in the nomenclature of West Bengal Swanirbhar Sahayak Prakalpa (WBSSP), an interest subsidy scheme of the state for the SHGs,” a senior WBSCL official maintained.The minister during his visit held a meeting with the SHG groups of all the six districts of North Bengal and the district administration and instructed them to speed up work for the ongoing projects and come up with new project proposals so that more number of people canavail the benefits. The minister also inaugurated the circuit bench of West Bengal State Consumer Dispute Redressal Commission in Siliguri.last_img read more

How the soothing sound of fathers typewriter inspired Thayil

first_imgThe clickety – clack from the typewriter of acclaimed writer-journalist T.J.S. George night after night was so soothing that it would lull his young son Jeet Thayil to sleep in the next room. “Perhaps that’s what first introduced me to the world of writing,” says Thayil, shortlisted in the past for the Man Booker Prize and whose latest offering, ‘The Book of Chocolate Saints’, was released in November.”For me, even now that’s a very soothing sound. If I hear it I can fall asleep… Because it is something that I heard a lot as a child… So I think, if you are a child and you see the adults in your life reading, you become a reader. In the same way, when you are a child and see the adults around you writing, you become a writer,” Sahitya Akademi recipient Thayil told in an interview.As a young boy, up till the age of 18, Thayil travelled a lot. Every time his father got a new job somewhere, the whole family would move with him. From Bombay to Patna, then to Delhi, back to Bombay, followed by Hong Kong and then New York, and back again to Hong Kong. But the inspiration too was continuous.”The first time I read poetry was from his bookshelf,” recalls Thayil – a hardcover first edition of the ‘Collected Poems of Dylan Thomas’. “I read Dylan Thomas, Ulysses and James Joyce when I was just 14 or 15.”Thayil said his travels shaped his perspective of the world. “When you are not in one place for very long and when you are exposed to many cultures as a child, I think it makes you more accepting, less judgemental; it makes you more open-minded about the world,” he elaborated.The author-poet’s self-discovery as a writer came at the age of 14 when he first read the English translation of a French poem ‘Le Léthé’ by Charles Baudelaire, which translates into ‘The River of Forgetfulness’.”I remember it had a physical effect on me, on my body. I felt it physically when I read this poem. My hair stood up. It had a very profound physical effect on me for a few seconds. I found it thrilling. And then I wanted to write something like that. Once that happened, you are changed. You are never the same person again,” Thayil maintained.What followed was a “totally natural process” of learning the art of writing. “In fact, it was so undisciplined because I was teaching myself. I had no idea, I just read everything that I could read. And then I tried to write. No one was there to tell me what’s good or what’s bad. And actually, that’s the only way to do it,” he added.Thayil’s literary works, particularly his poems, reflect a strong sense of grief and chaos, but he says he was very happy as a child. “But then childhood ended and so did happiness.” What also stopped was his conversations with his father. “We had a lot of problems,” he recalled about his late teens.After his return to India at 18, Thayil began experimenting with drugs. “And before I knew it, it had become a habit.” His addiction lasted for two long decades, the exact time that he worked as a journalist. “I financed my drugs from my journalism salary. So when I quit drugs at 40-something, I quit working, I didn’t need that job any more. I could just sit and write and write,” he explained.Thayil was back home in India but he no longer had a monthly salary and was working on a novel that would take five years to complete. When he first finished the draft of ‘Narcopolis’, it was an 800-page book, from which he carved out the 300-page version. From the 500 pages that were left, he started working on a new book. And split them into two other books, the first of which is ‘The Book of Chocolate Saints’.”It was much bigger than it is now; I deleted about half of the book and then wrote new stuff because once I started working on this, it became a totally different thing from it had been. And there was a moment in 2014 when I thought it was done. But it was nowhere near done. It was only in this last year that it really took its final shape,” he elaborated.Of course the father -son relationship is back to normal now. The only difference is that it is George who very often asks for Thayil’s feedback on his works these days. And why not, Thayil has come a long way! He won the DSC Prize for South Asian Literature in 2012 and a Sahitya Akademi award in 2013. He has also been shortlisted for the Man Booker Prize, the Man Asian Literature Prize and the Commonwealth Prize.One can just imagine the accolades that will come his way for arguably his best work so far – The Book of Chocolate Saints.
