50 million year old sperm cells found in fossilized cocoon

first_img Researchers find fossilized ciliate in 200 million year old leech cocoon (Phys.org)—A small team of researchers with members from institutions in Sweden, Argentina and Italy, has discovered fossilized sperm cells embedded in the walls of an ancient cocoon. In their paper published in the journal Biology Letters, the group describes how they came across the sperm fossils while studying a 50 million year old cocoon found on Seymour Island in Antarctica. © 2015 Phys.org Explore further Diagram illustrating the inferred mode of fossilization of microorganisms in clitellate cocoons, exemplified by a common medicinal leech (reproductive stages modified from Sims).

The distinctive egg cases (cocoons) of Clitellata, however, are relatively common in the fossil record, although their potential for phylogenetic studies has remained largely unexplored. Here, we report the remarkable discovery of fossilized spermatozoa preserved within the secreted wall layers of a 50-Myr-old clitellate cocoon from Antarctica, representing the oldest fossil animal sperm yet known. Sperm characters are highly informative for the classification of extant Annelida. The Antarctic fossil spermatozoa have several features that point to affinities with the peculiar, leech-like ‘crayfish worms’ (Branchiobdellida). We anticipate that systematic surveys of cocoon fossils coupled with advances in non-destructive analytical methods may open a new window into the evolution of minute, soft-bodied life forms that are otherwise only rarely observed in the fossil record.center_img Journal information: Biology Letters This document is subject to copyright.

Citation: 50 million year old sperm cells found in fossilized cocoon (2015, July 15) retrieved 18 August 2019 from https://phys.org/news/2015-07-million-year-sperm-cells-fossilized.html It is very rare to find fossilized examples of sperm cells because they are soft-bodied—they have no bones. Prior examples have mostly been found in amber. The fossils found by the researchers in this new effort were discovered by accident—the researchers were merely studying the intricacies of a fossilized worm, or leech (of the class Clitellata) cocoon they had found on the island to learn more about the creature that left it behind. In making their cocoon, the ancient worm would have applied jelly-like material to the walls, which would remain in that state for just a couple of days—sperm would have been deposited inside as a means of fertilization, and in a few cases become embedded in the cocoon wall, where it then became fossilized after the walls hardened.The fossilized sperm cells are tiny of course, just 60 micrometers long and resemble those of modern crayfish worms, the team reports, which is odd, because modern crayfish worms live only in the northern hemisphere. They have elongated head areas, a central region that holds the nucleus and extremely long tails. Dating has placed the age of the cocoon and its contents at 50 million years, which means the discovery is the oldest sperm cells ever found, by a margin of 10 million years.After hearing reports of nematodes being trapped in some other ancient cocoons, the team was encouraged to look closer at the specimen they had found—they used an electron scanning microscope to examine the walls of the cocoon and found multiple sperm cells, though the team notes, the fossils are not actual cells—there is no organic material there—instead they are impressions left by the cells which long ago deteriorated. To gain a better perspective of their find, they created 3D models. They also note that it is likely other such specimens exist in already found cocoons but have not yet been discovered because researchers have not looked close enough.last_img read more

Delhis date with Eve Ensler

first_imgStatistics say that one out of every three females in the world has faced some form of violence against her simply because she is a woman. But Delhiites need not know about statistics. Ask any woman around you and she will tell you of the harassment she faces day in and day out — if not at home then definitely once she steps out. While the Capital is protesting the recent gangrape and passing away of a braveheart, the fact remains that 16 rapes have happened since that fateful 16 December night. And in most cases, the rapists have been known to the victims — neighbours, uncles, cousins and even friends. Also Read – ‘Playing Jojo was emotionally exhausting’The fact remains that a woman is not safe. More so in the national capital. And therefore, there could not have been a more fitting stage for Eve Ensler — leading feminist and playwright — to launch her campaign 1 Billion Rising on 14 January. The movement, according to a statement from Poor-Box Productions (of which Mahabanoo Mody-Kotwal and Ensler are a part) and Make-A-Difference Foundation, is to ‘re-energise and refocus resources and attention on the scourge of violence against women’. Also Read – Leslie doing new comedy special with Netflix‘We at Poor-box Productions, who have had a long-standing relationship with Ensler and her work, will be working towards making 1 Billion Rising in India a huge success,’ it further states. Ensler will be coming to India in January to partner with Poor-Box Productions and others to energise and activate people towards this new movement and the objective will be to channelise the energy to end violence against women and girls. There will be a series of educational, informative and fund-raising events as part of the visit. The organisation also plans to rope in people from various strata of the society — from NGOs and corporate leaders to politicians, students, the media, lawyers and the civil society. The organisation also plans to raise funds for SNEHA (a shelter catering to survivors of violence in Dharavi in Mumbai) and give awards to some individual survivors of and warriors of violence against females.And this is not all. The Capital will once again get a chance to witness another performance of Ensler’s famous The Vagina Monologues (the Hindi version of the act  took place a couple of months back). The Vagina Monologues encourages women to be comfortable with their body and take away the stigma that women attach with the vagina.This time, it will be a celebration of 10 years of The Vagina Monologues in India. The play was brought here by Mahabanoo Mody-Kotwal and Kaizaad Kotwal as a way of using art to start a dialogue about ending violence against women and girls.The play brings along stories of various women and their brushes with sexual harassment. Kotwal and her team — Dolly Thakore, Dilnaz Irani, Rasika Duggal, Varshaa Agnihotri — Indianise the stories so that the audience can identify. So in place are the accents that are so common to various regions of the country.While getting the audience in splits, the play also manages to engage the audience and get the message across. They bring together experiences of girls and women of all ages. There are stories of a Maharashtrian woman who met a man who ‘loved to look at her’ to a Parsi woman who hasn’t been ‘down there since 1944’.  It is enlightening but not preachy. We would still recommend it to both men and women. It is therefore high time we leave the Victorian morality behind and be at ease with our bodies.DETAILAt: Blue Frog, One Style Mile, Mehrauli When: 8 January, 9 pm Phone:  30800300  Entry: Rs 1,000last_img read more

Step on the pedal eat up

first_imgThey call it the cafe for bikers. The perfect place to be when you want to take a break from a long drive and tuck in some good food. But well, if you aren’t a biker and all that you have ever done is perch precariously behind someone’s bike – Biker’s Cafe could still be the place for you.Nestled in the B8 market at Vasant Kunj, the cosy cafe is quite a welcome break away from the general buzz of the malls in that area. A little constrained in the number of people they can host inside, the cafe offers a cool set-up outside under big umbrellas. Enjoy the weather and tuck in – not the best option in summer. But the place is going to be a clear hit in winter.  Also Read – ‘Playing Jojo was emotionally exhausting’Eye-catching decor inside the cafe – parts of the Royal Enfield adorn the walls and gives it a wonderful laid back feel. Just the place to relax after a long day. Extremely reasonably priced food greeted us much to our surprise. In a posh locality, while the cafe should probably be making most of it since there aren’t others around to compete – Biker’s offers a meal for two in about Rs 500. Impressive!Starters were quite a filler as we got a taste of almost everything – dumplings, spring rolls and some really juicy chicken wings. The mushroom brushchetta get’s our thumbs up. When it comes to main courses – the chicken steak is a must try. The meat is wonderfully cooked and the mashed potatoes are perfect. They have an awesome ginger ale too. But the fire and loaded ice ball was the perfect end. A crust made of corn, museli and egg white covers a ball of ice cream served in a little bed of chocolate sauce in a martini glass. Approved. Head over. You won’t regret it!last_img read more

Poetry in clay

first_imgCeramic, unlike painting is poetic, while sculpture is more logical and scientific and as eminent artist Pablo Picasso said, sculpture is the art of the intelligence. Earth Echoes, a conglomerate of artistes, is organizing a four-day exhibition from January 6 to 9 at the Open Palm Court, India Habitat Center, Lodhi Road in the Capital where artistes will display creative works in clay. These artistes include Srirupa Sen, Sarika Malik, and Sneh Sharma. Arpita Bansal, Sandeep Marwah and Aruna Vasudev will be the Guests of Honour who will inaugurate the exhibition on January 6.

She has always been designing – from trousseau to calligraphy and lots more stuff like getting herself into ceramics which gives a three-dimensional touch to her thoughts. She puts her imagination to power into clay and produces tremendous art works. Also Read – Leslie doing new comedy special with NetflixHer current work includes The Ganesha and Serenity series. The Ganesha series is the expression of the eternal form of Ganesha and its essence, in a more abstract nature. The Serenity series is meditative and predominantly expresses her love for the abstract form and the balance and harmony that exists within it.It feels so fresh and pure when an experienced teacher adopts art as her child. Srirupa Sen is a teacher who has turned into innovative art. After teaching chemistry to University students for 25 years, she took voluntary retirement because of her love for art. After getting into ceramics, she got to know where she wanted to sink her hands, heart and soul. An artistic hobby turned into an obsession and this passion has not abated even after eight years. “The feel of moist clay whirling on the potter’s wheel and the vision of an indiscriminate lump of earth being transformed by my hands into an object of my imagination is a feeling which belies description”, says Srirupa Sen. Sneh Sharma from Delhi stepped into clay art work in 2009 at the Delhi Blue Pottery Studio. Clay is a mode of expression but for her it is like creating a piece of art by using different techniques. The love for Ceramics and sense of art grows bigger day by day, Sneh Sharmasays, adding, “I believe that every handmade work exudes spiritual beauty which significantly impacts the soul”.Where: Open Palm Court, India Habitat CenterWhen : January 6-9last_img read more

Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedJaya Sengupta, a resident of Action Area I in New Town, who owns a Labrador, said: “We need a good crèche for our pets. It is difficult to travel with them and most of the hotels in India do not allow dogs and private crèches are not up to the mark and do not treat animals properly.” NKDA has specified charges for keeping dogs in the crèche and for visiting the Out Patient Department (OPD) of the clinic. One needs to pay Rs 150 for the OPD services and Rs 750 a day for keeping large breeds and Rs 500 a day for keeping small breeds of dogs at the crèche. These apart, pet owners will have to pay Rs 10,000 as a security deposit. Apart from the clinic-cum-crèche, the development authority has come up with a cemetery for dogs where 25 animals can be buried. It becomes a major hassle for dog owners to get a suitable cemetery.

Depression anxiety may take same toll on health as smoking

first_imgLos Angeles: Anxiety and depression may significantly increase the risk of heart disease, stroke and arthritis, comparable to smoking and obesity, a study warns.Researchers from the University of California, San Francisco (UCSF) in the US looked at the health data of more than 15,000 older adults over a four-year period.The study, published in the journal Health Psychology, found that 16 per cent (2,225) suffered from high levels of anxiety and depression, 31 per cent (4,737) were obese and 14 per cent (2,125) were current smokers. Also Read – Add new books to your shelfParticipants with high levels of anxiety and depression were found to face 65 per cent increased odds for a heart condition, 64 per cent for stroke, 50 per cent for high blood pressure and 87 for arthritis, compared to those without anxiety and depression.”These increased odds are similar to those of participants who are smokers or are obese,” said Aoife O’Donovan from UCSF.”However, for arthritis, high anxiety and depression seem to confer higher risks than smoking and obesity,” O’Donovan said. Also Read – Over 2 hours screen time daily will make your kids impulsiveUnlike the other conditions investigated, the researchers found that high levels of depression and anxiety were not associated with cancer incidence.This confirms results from previous studies, but contradicts a prevailing idea shared by many patients, researchers said.”Our findings are in line with a lot of other studies showing that psychological distress is not a strong predictor of many types of cancer,” O’Donovan said.”On top of highlighting that mental health matters for a whole host of medical illnesses, it is important that we promote these null findings. We need to stop attributing cancer diagnoses to histories of stress, depression and anxiety,” O’Donovan said. The researchers discovered that symptoms such as headache, stomach upset, back pain and shortness of breath increased exponentially in association with high stress and depression.Odds for headache, for example, were 161 per cent higher in this group, compared with no increase among the participants who were obese and smokers.”Anxiety and depression symptoms are strongly linked to poor physical health, yet these conditions continue to receive limited attention in primary care settings, compared to smoking and obesity,” said Andrea Niles from UCSF.”To our knowledge this is the first study that directly compared anxiety and depression to obesity and smoking as prospective risk factors for disease onset in long-term studies,” Niles said.last_img read more

Bitcoin Breaks 1000 for First Time Ever

first_img This story originally appeared on CNBC Listen Now How Success Happens 3 min read Bitcoin continued its stellar rally on Wednesday, breaking above $1,000 for the first time and marking a rise of over 7,600 percent so far this year.Many analysts and investors have labeled bitcoin’s unfettered rise a bubble, yet greater awareness of digital currencies and relief following last week’s U.S. senate hearing have paved the way for fresh gains.Bitcoin traded as high as $1,030 on the Mt. Gox exchange, up 7,661 percent year-to-date from its December 31 close of $13.27.Digital currencies cleared a major hurdle when U.S. authorities signaled a willingness to accept them as legitimate payment alternatives at a November 18 U.S. Senate hearing on virtual currencies. The outcome allayed concerns that the government would take steps that could undercut mainstream adoption.”What we’re seeing is governments publicly announce and show that they recognize Bitcoin as a factor in the financial system and that they are considering how to regulate it – which is good for the currency,” Zennon Kapron, managing director of KapronAsiam, told CNBC.Comments from Federal Reserve Chairman Ben Bernanke were also seen as supportive. In an open letter to Senators before the Senate hearing Bernanke echoed comments from former Fed Vice Chairman Alan Blinder who spoke about digital currencies at a House of Representatives hearing in 1995.”Vice Chairman Alan Blinder’s testimony at that time made the key point that while these types of innovations may pose risks related to law enforcement and supervisory matters, there are also areas in which they may hold long-term promise, particularly if the innovations promote a faster, more secure and more efficient payment system,” Bernanke wrote.With much of the recent surge in Bitcoin demand coming from China, the U.S. senate hearing outcome has raised expectations that Beijing may steer away from heavily regulating digital currencies.”If either government were going to ban the currency outright, they would have made the decision now rather than later as it would really serve no purpose to delay beyond fueling speculation. So overly heavy-handed government regulation looks unlikely,” Zennon added.The digital currency has risen around 30 percent since its open on Tuesday, November 19, one day after the U.S. Senate hearing.Greater awarenessIncreased awareness also underlies bitcoin’s continued rise following a surge in mainstream media coverage and the preponderance of bitcoin-related events globally.Web-based searches for the term ‘bitcoin,’ which was added to Oxford Dictionaries Online this year, have seen a sharp increase since September according to Google data. On the day of the U.S. Senate hearing on virtual currencies, ‘bitcoin’ was the most popular search term, Google Trends showed.India will hold its first official Bitcoin conference in mid-December. According to a report in the Economic Times, the event is expected to see participation from the Reserve Bank of India – India’s central bank – as well as State Bank of India – the country’s largest bank.Billionaire entrepreneur Richard Branson said last Friday that his commercial space flight venture will accept bitcoin as payment.A test of whether the digital currency is being accepted more broadly could come with the second annual ‘Bitcoin Black Friday’ this week. The event will be held one day after the U.S. Thanksgiving holiday. According to the official promotional website for the event, merchants selling everything from web hosting to organic beer will offer special deals to anyone paying in Bitcoin.
