Twoheaded porpoise pulled from the ocean in the North Sea

The content is provided for information purposes only. Reports of conjoined twins in cetaceans (a family that includes whales, porpoises and dolphins) are rare, quite naturally because they occur in the open sea—it is also likely that most would die shortly after birth, like the specimen found by the fishermen. In this case, it appears the porpoise was born without the ability to swim.The fishermen knew the porpoise was a rare find, but because they were subject to rules preventing them from keeping caught mammals, they were compelled to throw it back into the sea—but not before taking multiple photographs, which they sent to the team at Deinsea.In studying the photographs taken by the fishermen, the researchers found signs that it had been born very recently—the dorsal fins were limp and the umbilical opening was still open—also, the tail had not stiffened, which meant it could not swim. Additionally, both of the heads still had rostrum hair, which disappears in healthy porpoises shortly after birth. The research team reports also that the porpoise was male, and that it had two heads that were fully formed. It also had individual pectoral fins, but just one body. They suggest it is likely the porpoise was symmetrically conjoined, which happens when two embryos fuse into one. In other cases, a single embryo does not split, preventing the development of separate twins.Though there have been nine previous cases of known conjoined sightings in cetaceans, this is the first for a porpoise. Researchers believe that twins, conjoined or otherwise, are rare in porpoises because porpoise calves in utero are too large. The development of conjoined twins would normally kill the mother, though it is not known if that was the case for the one found in the North Sea.

Evidence found for midsized black hole near center of Milky Way

first_img Over the years, scientists have found a lot of physical evidence of large and small black holes, but very little evidence for those in the mid-size range. This has led to an intense search, which until now, has come up mostly empty—mid-size black holes are exceedingly difficult to spot.The team reports that last year, they discovered a gas cloud near the center of the Milky Way that appeared to behave in odd ways—some of the gasses were moving faster than others. The cloud, named CO-0.40-0.22, was intriguing because not only did it represent the possibility of finding an intermediate black hole, but it could also explain how massive black holes come to exist at the centers of galaxies, such as our own Milky way.The team originally spotted the gas cloud using the Nobeyama radio telescope in Japan—but to learn more about what they had found required something bigger, so they ventured to Chile, where they gained access to the Atacama Large Millimeter/submillimeter Array. The researchers found that there was a dense part of the gas cloud near its center that also showed varying velocities. Better yet, just next to the clump, they found a source of radio waves that was very similar to those generated from the giant black hole at the center of Milky Way, but 500 times weaker. The two findings together suggested very strongly the presence of a mid-sized black hole. To add further evidence, the researchers built a simulation of the gas cloud and its characteristics, particularly the gas velocities, and found that it, too, pointed to a mid-sized black hole.These findings offer strong evidence of a mid-sized black hole, though it is not clear how it might have come to that location. But as more research is done and the find is confirmed, the mid-sized black hole could explain how giant black holes at the centers of galaxies are formed—by swallowing nearby mid-sized black holes, perhaps. More information: Tomoharu Oka et al. Millimetre-wave emission from an intermediate-mass black hole candidate in the Milky Way, Nature Astronomy (2017). DOI: 10.1038/s41550-017-0224-zAbstractIt is widely accepted that black holes with masses greater than a million solar masses (M⊙) lurk at the centres of massive galaxies. The origins of such ‘supermassive’ black holes (SMBHs) remain unknown, although those of stellar-mass black holes are well understood. One possible scenario is that intermediate-mass black holes (IMBHs), which are formed by the runaway coalescence of stars in young compact star clusters, merge at the centre of a galaxy to form a SMBH3. Although many candidates for IMBHs have been proposed, none is accepted as definitive. Recently, we discovered a peculiar molecular cloud, CO–0.40–0.22, with an extremely broad velocity width, near the centre of our Milky Way galaxy. Based on the careful analysis of gas kinematics, we concluded that a compact object with a mass of about 105M⊙ is lurking in this cloud. Here we report the detection of a point-like continuum source as well as a compact gas clump near the centre of CO–0.40–0.22. This point-like continuum source (CO–0.40–0.22*) has a wide-band spectrum consistent with 1/500 of the Galactic SMBH (Sgr A*) in luminosity. Numerical simulations around a point-like massive object reproduce the kinematics of dense molecular gas well, which suggests that CO–0.40–0.22* is one of the most promising candidates for an intermediate-mass black hole. (Phys.org)—A team of researchers with Keio University in Japan has found evidence of a mid-sized black hole near the center of the Milky Way galaxy. In their paper published in the journal Nature Astronomy, the group describes their study of a gas cloud cluster near the center of our galaxy and why they believe it offers evidence of a mid-sized black hole.

Outlook Uncertain On Gun Policy As Trump Signa

first_imgOutlook Uncertain On Gun Policy As Trump Signals Openness… Alex Brandon by NPR News Tim Mak 8.21.19 2:38pm President Trump said he’s willing to get behind some changes to background checks for gun-buyers as long as Democrats don’t move the goalposts and lead him down a “slippery slope.”The president told reporters on Wednesday that he continues to support new or altered checks without going into detail and he acknowledged that he’s been taking counsel on the issue from the National Rifle Association.Trump confirmed he’d spoken with NRA CEO Wayne LaPierre on Tuesday but not some news accounts that suggested the two men had agreed there would be no movement on background checks.Instead, Trump said he and LaPierre mostly talked about “concepts” and “certain weaknesses we want to fix” in the current process for buying guns. Trump suggested he was willing to negotiate something with Democrats: “Assuming they really want to get this done, we can get this done.”Precisely what “this” might involve isn’t clear as Trump and Democrats appear far apart on gun proposals following two mass shootings earlier this month in Texas and Ohio.Political leaders on either end of Pennsylvania Avenue have suggested they’d be open to new gun policies, including Senate Majority Leader Mitch McConnell, R-Ky. But one difficulty in understanding the state of play has been Trump’s own changing position. Two weeks ago, he wrote on Twitter that “Republicans and Democrats must come together and get strong background checks.” After his phone call with the NRA leader on Tuesday, Trump played down the need for such action.”We have very, very strong background checks right now,” Trump told reporters in the Oval Office. Continued Trump: “But we have, sort of, missing areas and areas that don’t complete the whole circle. And we’re looking at different things. And I have to tell you that it is a mental problem … It’s not the gun that pulls the trigger; it’s the person that pulls the trigger.”Then on Wednesday the president repeated some of those points and added that what he feared was a tactic by Democrats in which they opened negotiations but then insisted on elements that would take any bill beyond the point he was willing to support.Opponents call for new actionDemocrats say the recent shootings reinforce the need for significant new action; the House Judiciary Committee has announced it’s going to return early to Washington to take up legislation on “red flag” laws and assault weapons.”For years, Democrats have worked with the survivors of gun violence on legislation and promised that we would never stop until we got the job done,” House Speaker Nancy Pelosi wrote to lawmakers this month. “Public sentiment is in favor of gun violence prevention,” she said. “The American people must weigh in with the Congress and the president.”Democratic presidential hopefuls also faulted what they called Trump’s capitulation to gun rights groups. “Trump isn’t in charge — the NRA is,” wrote California Sen. Kamala Harris.Former Vice President Joe Biden vowed that if he’s elected not only would he pursue “universal” background checks but also reinstate the 1994 assault weapons ban.Trouble inside the associationThe president’s adoption of the NRA’s leitmotif that “guns don’t kill people, people kill people” underscored the enduring influence of the gun rights group even as it also undergoes significant internal turmoil. For example, on the same day that LaPierre spoke with the president, two NRA board members decided to resign. Country music singer Craig Morgan stepped down, as did NASCAR team owner Richard Childress. Childress did not refer to the internal power struggles or the multiple investigations taking place into the NRA’s finances. “It is necessary for me to fully focus on my businesses,” Childress wrote, in a letter obtained by NPR. “My hope is that the NRA will move forward with a focus on its important mission.”Amid allegations of financial impropriety, the New York and Washington, D.C. attorneys general have launched investigations into the gun rights group. This comes in addition to numerous congressional probes into the organization’s finances. Morgan and Childress’ resignations brings the total number of resignations from the board to seven, out of a total of 76 board members. A number of board members have resigned in recent weeks due in part to what they claim is an inability to get straight answers about the group’s financial situation.Copyright 2019 NPR.

Poor sleep leads to skin ageing

first_imgScientists have shown that lack of quality sleep can lead to ageing of skin, says a study. In a first-of-its-kind clinical trial, physician-scientists at University Hospitals (UH) Case Medical Centre, US, found that sleep quality impacts skin function and ageing.The recently completed study demonstrated that poor sleepers had increased signs of skin ageing and slower recovery from a variety of environmental stressors, such as disruption of the skin barrier or ultraviolet (UV) radiation. Also Read – ‘Playing Jojo was emotionally exhausting’Poor sleepers also had worse assessment of their own skin and facial appearance, reports Science Daily.The research team, led by lead investigator Elma Baron, director of the Skin Study Centre at UH Case Medical Centre, presented their data recently at the International Investigative Dermatology Meeting in Edinburgh, Scotland, in an abstract titled ‘Effects of Sleep Quality on Skin Ageing and Function’.‘Our study is the first to conclusively demonstrate that inadequate sleep is correlated with reduced skin health and accelerates skin ageing. Sleep deprived women show signs of premature skin ageing and a decrease in their skin’s ability to recover after sun exposure,’ said Baron.last_img read more

Donotcall

first_imgThe mobile subscribers are at the mercy of the unruly tele-callers who end up making calls at the most unwanted hour. It has been a daily routine for the subscribers to bear such calls and SMS’. According to data accessed from the telecom ministry 9,41,691 complaints  were received by service providers between 27 September, 2011 to 3 July, 2014 while the number of notices sent to unregistered telemarketers from 27 September, 2011 to 24 May, 2013 were 2,86,910. Also Read – A vintage affair with Shyam SundarA total of 4,94,688 of telephone disconnections of unregistered telemarketers were undertaken from September 7, 2011 to July 3, 2014. The data further shows that 8,25,404 connections were additionally disconnected on account of Unsolicited Commercial Communications (UCC) sent (proactive/call back numbers/entities). The number of notices sent to telemarketers with deduction in their security deposit and total amount deducted so far from 27 September, 2011 to 3 July, 2014 were 4,03,173. While 20 telemarketers were blacklisted during the same dates, 2,24,341 unregistered tele marketers were blacklisted for two years till 3 July, 2014. Given the high frequency of pesky calls, each mobile subscriber today looks for a solution to stop these unwanted messages and calls. Also Read – Melodious Mavericks – Jatin LalitFew years back the Telecom Regulatory Authority of India (TRAI), had introduced the DND (Do Not Disturb) service. A mobile subscriber could register his/her mobile number on DND and as per policy all unwanted messages and calls should have been stopped. But even after registering for the service, these calls and messages haven’t stopped even until now.  TRAI notified the ‘Telecom Unsolicited Commercial Communications (UCC) Regulations, 2007’ dated 5 June, 2007, putting in place a framework for controlling unsolicited commercial communications. It envisaged establishment of a National Do Not Call (NDNC) Registry to facilitate registration of requests from customers who do not wish to receive UCC. To improve the effectiveness of the framework, TRAI had subsequently amended these regulations from time to time by issuing amendments,’ said union telecom minister Ravi Shankar Prasad in the Rajya Sabha on 11 July, 2014.‘In order to make the regulatory framework for curbing UCC more effective, TRAI issued ‘Telecom Commercial Communications Customer Preference Regulations, 2010’ on 1December, 2010.  As per the provisions of the Telecom Commercial Communications Customer Preference Regulations, 2010, registration of telemarketers has started on the web portal www.nccptrai.gov.in from 15 January, 2011. Registration of customer preference on National Customer Preference Registry (NCPR) has started from 10 February, 2011. All the provisions of these regulations have come into force from 27 September, 2011,’ he added. Meanwhile the subscribers despite having the assurance from the operators, feel the heat of unwanted calls. ‘I receive so many spam SMS in a day that I have now lost interest in reading them. Sometimes even genuine text messages are kept unread or read after much delay due to this issue,’ says Om Prakash, an insurance company manager. Very few people have stopped receiving calls from every unknown number, he adds. A large number of telemarketers did not register with the Department of Telecommunications (DOT) as required, TRAI said earlier. Telemarketers have also shifted from voice calls to short message service (SMS), it added.The NDNC did not work very well also because many telephone users did not subscribe to the service. In a recent consultation paper, TRAI has proposed that subscribers should be instead offered an ‘opt-in’ option which requires them to register only if they want telemarketing calls, rather than the other way around. A number of countries are moving in this direction, according to TRAI. Another option proposed by TRAI is to make it easier for subscribers to register with the NDNC through the use of toll free special numbers, and interactive voice response systems.To force telemarketers to register with the DOT, TRAI is suggesting a ceiling on the maximum number of calls as well as SMS per day from a telephone number, wireless as well as wireline, so that it can force telemarketers to register with the telecommunications department. Analysts are however not sure how this will work. Mobile subscribers are a large and affluent market for telemarketers. Even mobile service providers cannot sometimes resist the temptation to SMS their subscribers with a variety of unsolicited offers, they add.last_img read more

Water level has depleted in Bengal but not reached dangerous levels

first_imgKolkata: State Water Resources Investigation and Development and Panchayat & Rural Development minister Subrata Mukherjee said on Thursday that ground water level in the state has depleted, but assured that it has not reached a dangerous level.”70 percent of the water used for agricultural activities is still procured from groundwater. There has certainly been a depletion in ground water level, but it has not reached dangerous levels yet. However, we are taking all possible measures to store water,” Mukherjee said, while speaking at an interactive session on “Assuring Irrigation to Small & Marginal Farmers of West Bengal” at Merchants’ Chamber of Commerce & Industry. Also Read – Rain batters Kolkata, cripples normal lifeThe minister said that in districts like Hooghly, West Burdwan and East Burdwan, they have found out that they need to go 200 feet below the ground for irrigation water. “We earlier had to put in two to three pipes underground for the purpose,” the minister said.He referred to “Jal Dharo Jal Bharo”, a unique state initiative to conserve rain water in all kinds of water bodies like tanks, ponds, reservoirs, canals etc. According to the minister, as of June 2018, 2,44,149 water bodies/water retention structures have been created in convergence with the state Water Resources Investigation & Development and Panchayat & Rural Development departments. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedHe also mentioned about a Rs 3,000 crore loan from World Bank for developing minor irrigation with a command area of 5 hectares and above.The Water Resource Investigation department has already constructed 1,500 check dams across the state, including a good number in the hilly areas for storing water for irrigation.”There are a number of rivers in the state that are of perennial nature. Water from the check dams are being used for irrigation in the areas where rivers dry up,” he said. The minister also spoke about a location-specific scheme for comparatively underserved areas of the state, named “Jalatirtha” since 2014-15, in five Paschimanchal districts of Bankura, Birbhum, Paschim Medinipur, Jhargram & Purulia, which was later extended to Sunderban areas and hilly areas of Darjeeling & Kalimpong.”The achievable minor irrigation potential in the state has been estimated at 44.34 lakh hectares, out of which 31.34 lakh hectares is expected to be drawn from ground water resources, with 13.00 lakh hectares from surface water. Owing to successful implementation of irrigation, the crop intensity has increased from 177 percent in 2010–11 to 188 percent,” Mukherjee said.According to the minister, the small and marginal farmers constitute 96 percent of the farmers and hold around 80.7 percent of the land, the average size of land holding being 0.77 hectare.last_img read more

Framing inspiration

first_imgCultural exchange has always benefited people around the world, be it through Fine Art or Performing Art forms. The 2nd edition of International Art Symposium is an upcoming event presented by ‘I Art’ and conceptually developed by two Delhi based emerging contemporary artists Sangeeta Kumar Murthy and Suchismita Sahoo. the duo are not only engaged  to paintings and art installations but also have a focus of bringing a little change towards Indian Art in the global platform through intercultural exchange programmes. Their togetherness has brought a new platform for emerging artists from India and abroad. Also Read – Add new books to your shelf Artists from six countries and another eleven artists from different corners of India are participating in the symposium. ‘I Art’ starts scouting for young and upcoming art talent throughout the world and invite them for a few days’ stay in India. During their stay at a private residence they can freely show and present their work. Separate workshops are arranged for every form of art (Painting, Sculpture, Art installation, Photography and Apparel designing).  Also Read – Over 2 hours screen time daily will make your kids impulsiveIt is intended that during their stay, the artists can show their capabilities and skills by making their own art. The presentations and works are discussed while a file of their work is laid out. Participating artists from around the globe include Lukaszk Rupski (Poland), Luka Radojevic (Serbia), Tg Thet (Myanmar), Sabiha Hadzimuratovic (Bosnia), Yura Tkachenko (Russia), Valentina Dusavitskaya (Russia) and Constantin Migliorini (Italy).Artists participating from India include Sudha Sama, Kamlesh Gandhi, Parveen Upadhaya, Ashish Bose, Barkha Jain, Ritu Gupta, Rajesh Harsh, Kavita Wig, Shraboni Banerjee and Manissha Khanna.  According to Rajesh Harsh, a participating artist, “This platform would help us in maintaining good relations with people who think differently, as inspiration can be drawn from anyone and anything. This platform would help the line blur between the artists of different countries. Sangeeta Kumar Murthy and Suchismitha Sahoo says, “We have always represented India in different countries in various symposiums and the cultural exchange that happens has always been enriching because it helps open avenues.It helps in understanding different cultures, traditions and minds of people. We conceived the idea of holding one in India as this would give an opportunity to Indian artists to showcase and discuss their work. It would open new horizons for artists who might not have got the kind of exposure they wanted. This time we have artists who are exhibiting paintings as well as sculptures. Also, the ratio of female participation is more.”last_img read more
