first_imgA federal judge in Texas issued a ruling Friday declaring the Affordable Care Act unconstitutional, apparently setting the stage for another hearing on the health care law by the U.S. Supreme Court.The ruling by U.S. District Judge Reed O’Connor invalidates what’s commonly referred to as Obamacare nationwide, and casts into doubt the survival of the law on the eve of the deadline for tens of millions of Americans to sign up for health care coverage in 2019.The ruling comes in a lawsuit brought against what was one of the major domestic achievements of the Obama administration. An alliance of 19 Republican attorneys general and a governor led by Texas Attorney General Ken Paxton challenged the law.As NPR’s Alison Kodjak explained on All Things Considered,”The lawsuit had to do with whether when Congress last year repealed or eliminated the penalty for not having insurance — it was a tax penalty for people who didn’t have insurance — whether that meant the rest of the law didn’t apply anymore. The court case argued that all of the pieces of the law were dependent upon each other, so by eliminating the penalty the rest of the law fell apart. The judge agreed with that opinion.”In his 55-page opinion, Judge O’Connor said the debate over the ACA’s interlocking provisions is “like watching a slow game of Jenga, each party poking at a different provision to see if the ACA falls.”In a statement, White House press secretary Sarah Sanders praised the ruling.”Obamacare has been struck down by a highly respected judge. The judge’s decision vindicates President Trump’s position that Obamacare is unconstitutional. Once again, the President calls on Congress to replace Obamacare and act to protect people with preexisting conditions and provide Americans with quality affordable healthcare. We expect this ruling will be appealed to the Supreme Court. Pending the appeal process, the law remains in place.”Shortly afterwards, President Trump tweeted, “As I predicted all along, Obamacare has been struck down as an UNCONSTITUTIONAL disaster! Now Congress must pass a STRONG law that provides GREAT healthcare and protects pre-existing conditions.”California Attorney General Xavier Becerra, who led the coalition of states that defended the ACA promised to continue the court fight to preserve the law.Rep. Nancy Pelosi, who is expected to be House speaker when Democrats come into the majority next month, tweeted, “Tonight’s absurd ruling exposes the monstrous endgame of the GOP’s all-out assault on people w/ pre-existing conditions & the ACA. When @HouseDemocrats take the gavel, the House will swiftly intervene in the appeals process to #ProtectOurCare!”Copyright 2018 NPR. To see more, visit https://www.npr.org.last_img read more

Disabled and older people have compared a council

first_imgDisabled and older people have compared a council’s plans to cut £5 million from its adult social care budget to “social cleansing” and have accused it of “treating people no better than animals in Longleat”.The comments were included in The Voice of those Affected, a report by Healthwatch Merton into proposed cuts by Merton council in south-west London.The report was commissioned by the council after heavy lobbying by campaigners, and was based on comments by 72 service-users and carers during a series of focus groups.The report was released as more than 20 campaigners – many of them disabled people – protested outside the council’s offices before a committee meeting this week at which councillors discussed the proposed cuts.The protesters had heard that members of the council’s ruling Labour group had already voted in secret – although not unanimously – not to increase council tax for 2016-17, or to take advantage of new powers allowing councils to increase council tax by two per cent a year to boost adult social care spending.Six speakers, including Lyla Adwan-Kamara, chief executive of Merton Centre for Independent Living (MCIL), and two disabled people affected by the proposals, spoke to the council’s healthier communities and older people’s scrutiny panel about the report and the likely impact of the cuts.Adwan-Kamara said afterwards that those speeches “brought to life what was in that report, what had been happening to them and even worse what was going to happen to them”.Following those and other presentations and discussions, the panel rejected three proposed cuts – to care and support packages, to staffing, and to scrapping a respite service – and agreed to send them back to the council’s cabinet for “review and reconsideration”.People who took part in the Healthwatch Merton focus groups said the cuts would damage their health, sever social connections, and affect every aspect of their lives, leaving some believing that life was no longer worth living.Words and phrases used to describe the cuts included “disgusting”, “devastating”, “wickedness” and “survival of the fittest”.One told a focus group: “It is like social cleansing, they are trying to get rid of the people they don’t need.”One man in his 80s said – apparently quite seriously – that he would now have to “start practising to eat less from now on”, while another contributor said: “I will end up in my flat like a hermit, self-harming again.”Another said: “I was placed in a care home. It feels like a prison. I pay £600 per week to live somewhere I hate and I don’t use any of the services.”One focus group member said the council had become “less and less supportive”, and accused it of “withdrawing help and taking things back to Victorian times”, while another said: “I had to beg social services to take notice of me. What chance is there going to be for people that don’t have a voice like I did?”The report calls for the council to commission a more detailed, independent evaluation of the impact of the cuts on disabled and older people, and concludes: “One of the key feelings voiced was a sense of betrayal and abandonment by Merton Council.“People talked of being left behind, being left on the scrapheap, and not being treated equally.”The report says there were people crying in nearly every one of the focus groups, and it warns that if the cuts go ahead, people will “potentially be making heat or eat type decisions as they may need to pay for their own care, or pay more for services that they need”.After the scrutiny panel meeting, Adwan-Kamara told Disability News Service that it was the first time the council had “really listened to our members”, but that the £5 million in cuts was “still hanging over people’s heads”.She said of the Healthwatch Merton report: “I had a fairly clear view of what people would say, because we have been hearing this through our casework.“As a centre for independent living, we knew what the issues were, but to see those comments written down in black and white and made so explicit and clear was really emotional.”She said the Labour group’s decision not to increase council tax was “unconscionable”.She said: “They have that opportunity and they are refusing to take it. They have made a choice not to raise council tax, so they have made a choice not to support the most vulnerable people in Merton.”A spokeswoman for Merton’s Labour group confirmed the scrutiny panel had asked the cabinet to look again at the three proposed cuts to adult social care, and said the budget would now be considered by the cabinet on 15 February, with a final decision taken by the full council on 2 March.She said that the Labour group “intends to keep its promise to residents to freeze council tax” and would not take advantage of the two per cent increase option.Cllr Stephen Alambritis, leader of the council, said in a statement: “I promised residents a four year council tax freeze and if there’s one thing you can say about me I keep my promises.  “I’m a business-man and I believe in running a business-like council, making what we do more efficient so we can continue to deliver the services people need the most.”Cllr Mark Allison, the cabinet member for finance, added: “The government have cut council funding by more than 40 per cent but in Merton we have done our best to protect adult social care services by ensuring it gets a lower share of the cuts than other departments, and by adding a further £12 million to its budget.  “As a result we have managed to keep the amount we spend on adult social care virtually the same since 2010.”last_img read more

Zuckerberg Some Tech Is Worrying but Not Facebook

first_img News reporter May 26, 2017 Zuckerberg: Some Tech Is Worrying, but Not Facebook Mark Zuckerberg The story of Facebook’s founding has entered American legend, but its founder and CEO Mark Zuckerberg couldn’t resist briefly rehashing its conception in a Harvard dorm room during a commencement speech at his alma mater on Thursday.Zuckerberg, who founded Facebook before dropping out of Harvard, also used his speech to explain his view of technology in starkly clear terms: he believes that technological progress as a whole is threatening to many people’s way of life, but certain individual technologies, including Facebook, actually change people’s lives for the better. It all comes down to a sense of purpose, according to Zuckerberg. Millennials like him have it, while many older people have lost it thanks to technological change.”When our parents graduated, that sense of purpose reliably came from your job, your church, your community,” Zuckerberg said. “But today, technology and automation are eliminating jobs. Membership in a lot of communities has been declining, and a lot of people are feeling disconnected and depressed, and are trying to fill a void in their lives.”His remarks echo those of many government and business leaders who are grappling with the prospect of robots taking over people’s jobs. The European Union is even considering a form of social security tax on automated factories to make up for an anticipated decline in wages being paid to humans. Others, including U.S. Secretary of Labor Steve Mnuchin, aren’t as worried about a robot revolution.To Zuckerberg, though, not all technology is menacing, especially not the world’s largest social network. Echoing the company’s motto, he explained that Facebook is the way the world connects, and he suggested that the world is a better place because of it. “This idea was so clear to us, that all people want to connect, so we just kept working on it,” he said, recalling early coding sessions in his dorm room.What Zuckerberg didn’t get around to in his speech is that more than 10 years after those sessions, Facebook is now a multinational company that snapped up many smaller ones, including Instagram, which the Royal Society for Public Health recently determined to be the “most detrimental” social media platform for young people’s mental health and wellbeing.

Study Window screens can suppress mosquito populations reduce malaria in Tanzania

first_img Source:https://www.thelancet.com/ Mar 22 2019In an article published today in Lancet Planetary Health, a team from the Ifakara Health Institute (IHI) and Liverpool School of Tropical Medicine (LSTM), provides evidence that even window screens with no insecticide suppressed mosquito populations and dramatically reduced malaria prevalence in the Tanzanian city of Dar es Salaam.The study team has also worked with local and national government partners for over a decade to develop practical affordable implementation systems for community-based application of environmentally-friendly biological insecticides that selectively kill mosquito larvae in puddles, drains, river fringes, ponds and other sundry stagnant water bodies. Dr Prosper Chaki, who co-led the study, says “We are pleased that our efforts over all these years have culminated in government-funded scale up of larviciding, first across all of Dar es Salaam, and then to all major urban centres in Tanzania. Also, our government has invested domestic treasury funding into construction of a manufacturing plant for biological control products in Kibaha, just outside the city, which is now fully operational.” However, previous external analyses of the first large-scale pilot in Dar es Salaam indicated that larviciding only reduced malaria prevalence by 21%. Furthermore, this previous analysis3 provided no explanation for the much larger reductions of malaria prevelance that occurred over the study period, which steadily declined from >28% in 2004 to <2% by 2008.The IHI and LSTM team therefore re-assessed these epidemiological data to see how much of this remarkable 97% drop in malaria prevalence could be attributed to other factors. Only the coverage of complete window screening consistently increased to levels high enough to have any meaningful impact. While only 40% of houses had complete window screening at the start of the study in 2004, coverage had more than doubled to 86% by 2008. This surprisingly rapid scale up of window screening coverage was unplanned and spontaneous, implemented by households at their own expense, using flexible plastic screening which they found easy to install. This steady rise in window-screening coverage was statistically associated with a 92% reduction of malaria prevalence amongst residents, accounting for most of the spectacular overall decline in malaria prevalence. "Good-quality housing is a crucial factor in reducing malaria transmission across the spectrum of malaria endemicity." says Dr Emmanuel Chanda at the World Health Organization Regional Office for Africa in Brazzaville, Congo. In his supporting editorial, he continues "Killeen and colleagues' findings fall within the context of research efforts to provide hard evidence for the public health value of house screening.". Interestingly, mosquito biting rates were also reduced by as much as 92%, and impact was greatest for the most efficient malaria vector species that depend heavily on human blood. "People who live with mosquitoes protect themselves by taking advantage of any products they can access and afford." says Dr Nicodem Govella, a co-author of the study who also develops new methods for measuring just how much mosquitoes prefer and depend on human blood. He continues "Here is an encouraging example from the citizens of Dar es Salaam, who spent millions of dollars of their own money to protect their houses and families, but also protected their neighbours by making life tougher for mosquitoes".Related StoriesSouthern Research team aims to discover new, safer antimalarial medicinesHuman liver cell protein aids development of malaria parasite, study findsMalaria free status for Algeria and ArgentinaIn addition to revealing the remarkable contribution of window screens to this near-collapse of malaria transmission, this re-analysis also yielded a more encouraging estimate for the impact of regular larvicide application. Larviciding halved malaria prevalence by reducing malaria vector abundance, consistent with subsequent evaluations of scale up across the remainder of the city.In addition to demonstrating that mosquito-proofed window screening may have far greater impacts upon malaria than previously thought, these observations also challenge the view that it is too expensive and impractical for widespread use in poor countries. "While Dar es Salaam is a big city, we think our observations also have important implications for rural Africa.", says Dr Gerry Killeen who led the study. "Historically, most rural African houses have been made with mud and sticks for the walls and grass thatch for the roofs. Mosquitoes readily entered through the eave gaps between the wall and roof, which were left open for ventilation because these simple house designs lacked windows. However, Africa is changing faster than ever before, and that picture is rapidly becoming outdated across much of the continent. Houses ventilated by windows and built with bricks, timber and iron sheets are increasingly common even in rural Africa. The people who live with mosquitoes and malaria invest as much as they can in better houses, which are easier to protect with readily-available netting materials". "This study shows how the relatively simple intervention of installing window screens was taken up beyond a research study setting and led to a remarkable reduction in malaria infections in the wider community. These findings demonstrate that it can take more than a decade for research to have a real impact on the communities that need it most", says Branwen Hennig, Senior Portfolio Lead at the Wellcome Trust one of the major sponsors for the study. The authors also note that ongoing housing improvements across rural Africa are closely associated with declining malaria burden and that even bigger reductions may be possible if they could be treated with insecticides.last_img read more

Nanovaccine boosts immunity in mice with gut microbiomemediated metabolic syndrome

first_img Source:http://news.cornell.edu/stories/2019/03/nanovaccine-boosts-immunity-sufferers-metabolic-syndrome Reviewed by James Ives, M.Psych. (Editor)Mar 29 2019A new class of biomaterial developed by Cornell researchers for an infectious disease nanovaccine effectively boosted immunity in mice with metabolic disorders linked to gut bacteria – a population that shows resistance to traditional flu and polio vaccines.The study is the first to explore the interrelationship among nanomaterials, immune responses and the microbiome, an increasingly important area of research. The microbiome – the collection of microorganisms living in the body – is believed to play a critical role in human health.”This paper highlights how the microbiome can impact our engineered vaccines and how we can overcome these problems by developing advanced materials,” said Ankur Singh, assistant professor in the Sibley School of Mechanical and Aerospace Engineering (MAE) and the Meinig School of Biomedical Engineering (BME).Singh is senior author of “Immunomodulatory Nanogels Overcome Restricted Immunity in a Murine Model of Gut Microbiome-Mediated Metabolic Syndrome,” which published March 27 in Science Advances. The paper’s first author is Matthew Mosquera, a doctoral student in engineering.”This work opens up a new, very exciting area of investigation into how biological factors and underlying disease conditions impact the performance of established nanovaccines,” said Singh, who is also a member of the Englander Institute for Precision Medicine at Weill Cornell Medicine and the newly formed Cornell Center for Immunology. “More importantly, it shows how you can use these engineered materials and make them more workable across a wider population to overcome immunity to vaccines.”More than a third of Americans and a quarter of people worldwide are believed to suffer from metabolic syndrome, an umbrella for several disorders including obesity, inflammation and insulin resistance.The gut microbiome is among the factors that can cause metabolic syndrome, and researchers are interested in microbiome-induced metabolic syndrome because of evidence linking both the microbiome and metabolic disorders to the immune system.”Understanding how the microbiome affects future engineered vaccines is of utmost importance from a public health perspective,” said Ilana Brito, assistant professor of biomedical engineering and a co-author of the paper. “This research will open up new avenues for exploring how specific components of the microbiome alter immune responses. When engineering new vaccines, it’ll be important to design materials that are effective across a diversity of microbiome compositions.”Previous research showed that traditional human flu and polio vaccines fail in mice that have metabolic disorders caused by disruptions to their gut biomes. “That motivated us to look into what happens with nanovaccines, which can be better than soluble vaccines, to better understand the role of underlying obesity and inflammation that develops in gut alterations,” Singh said.Related StoriesStructure of bacteria responsible for traveler’s diarrhea decipheredMetabolic enzyme tied to obesity and fatty liver diseaseAMSBIO offers new, best-in-class CAR-T cell range for research and immunotherapyNanovaccines, which are generally composed of nanomaterials, can be taken up by cells in the immune system and have been found to induce stronger immunity than traditional soluble vaccines in pre-clinical models.But researchers found that the most widely used type of nanovaccine, made of poly(lactic-co-glycolic acid) (PLGA), is not very effective in mice with gut-initiated metabolic syndrome. When researchers tested PLGA nanovaccines on the mice, it was less successful than they had expected, even with the addition of a widely used immune booster.”We asked, are there ways to overcome this restricted response by engineering new nanomaterial vaccines?” Singh said. “Then we looked deeper into a new class of material that modulates the immune system, pyridine functionalized poly(2-hydroxyethyl methacrylate), the potential of which we recently discovered.”The new material formed a stable nanogel with protein antigens, which was found to be effective under gut-initiated metabolic syndrome conditions. Working with Cynthia Leifer, associate professor of immunology in the College of Veterinary Medicine, the group discovered that this new material stimulates a receptor that recognizes pathogenic danger signs on microbes.”This study is important because it shows that these nanogels can supply both antigen and adjuvant without the need for an extra immune booster, which likely contributes to their stronger immune activation and ability to overcome limitations imposed by diseases or altered microbiomes,” Leifer said. “Immunomodulatory therapies are a hot topic, and materials-based immunomodulation approaches are in their infancy. There is so much that can be done with them.”While it has been established that the microbiome impacts the immune system, these findings suggest that nanovaccines can influence the microbiome in return.”Nanomaterials can modulate the composition of the gut microbiome – I think that’s of tremendous importance to the entire field and could have implications in material design,” he said. “Whether it’s a causative effect or the reason behind this is not very well understood – there are several hypotheses that remain to be tested, so this will be future work for us.”last_img read more

Maximal running shoes may raise injury risk even after transition period

first_imgReviewed by Kate Anderton, B.Sc. (Editor)Apr 16 2019A six-week transition period did not help wearers adjust to “maximal” running shoes, indicating that increased impact forces and loading rates caused by the shoe design do not change over time, a new study from Oregon State University – Cascades has found.The shoes, which feature increased cushioning, particularly in the forefoot region of the midsole, affect runners’ biomechanics, leaving them at increased risk of injury, said Christine Pollard, director of the Bend campus’s Functional Orthopedic Research Center of Excellence (FORCE) Lab and a co-author of the study.”These shoes may work for certain people, but right now we just don’t know who they are good for,” said Pollard, an associate professor of kinesiology at OSU-Cascades. “The findings suggest that people aren’t really changing the way they run in the shoes, even after a six-week transition, potentially leaving them at increased risk of injury.”The study was published recently in the American Journal of Sports Medicine. The lead author is J.J. Hannigan, a post-doctoral researcher in the FORCE Lab.Maximal shoes have been growing in popularity since being introduced in 2010. More than 20 varieties of maximal shoes are on the market, but little research has been conducted on the shoes to understand their effect on running biomechanics. Controlled studies, like the research at the FORCE Lab, help clinicians make science-based recommendations to runners.Researchers in the FORCE Lab previously conducted a study of people running in the shoes before and after a 5K treadmill run; the findings from that study suggested that the maximal shoes may increase impact force and loading rates, which indicate a greater risk of injury.The new study was designed to build on the previous research and see how a six-week transition to the maximal shoe might affect runners’ biomechanics.”We wanted to look beyond any novelty effect the shoe might have,” Pollard said. “It’s a very new area and we have a lot of work to do to understand how these shoes affect running mechanics.”Related StoriesSenate panel makes surprisingly fast work of ‘surprise medical bills’ packageExtremely strenuous exercise can overload the heart without increasing cardiac riskChildren living in the countryside have better motor skills than their peers in metropolitan areaThe researchers studied 20 runners, a mix of men and women, between the ages of 18 and 45, who ran at least 15 miles a week. The runners participated in two biomechanical testing sessions in the lab, each session about six weeks apart. They completed a series of running trials wearing maximal shoes and also wearing traditional running shoes.After the first testing session, the runners received a maximal shoe transition schedule to follow. They continued their regular running mileage but gradually increased the percent of their mileage run in the maximal shoe over the six-week period, with the last two weeks only in the maximal shoes.The results showed there were no changes in running mechanics over time in either type of shoes. The study did show increased impact forces and loading rates in the maximal shoe, supporting results of the earlier study. There was no difference in those biomechanics after the transition to the maximal shoes.”The concern in the maximal shoes is that you have this mass you’re repeatedly loading. How are you attenuating that?” Pollard said. “We also saw changes in ankle kinematics, or the angular movement in the joints. With the maximal shoes we saw prolonged eversion, which likely increases stress on the legs and could lead to injury.”More research is needed to understand how maximal shoes affect biomechanics, Pollard said. For now, runners and clinicians who work with runners should be cauti”We really don’t know enough to be recommending them,” said Pollard, who also is a licensed physical therapist. “If someone is going to try them out, I would suggest they try them out on a treadmill at a running store to see how they feel. How they feel then is how they’ll feel in six weeks.” Source:https://oregonstate.edu/last_img read more

Study proves that brains of pairs of animals synchronize during social situations

first_imgReviewed by James Ives, M.Psych. (Editor)Jun 24 2019FINDINGSUCLA researchers have published a Cell study showing that the brains of pairs of animals synchronize during social situations. The synchronized activity not only arose during various types of social behavior, but also the level of synchronization actually predicted how much the animals would interact. The team also found that brain synchrony arises from different subsets of neurons that encode the behavior of the self vs. the social partner, and that the dominant animal’s behavior tends to drive synchronization more than behavior of the subordinate.BACKGROUNDConsiderable research has been devoted to studying brain activity in individual animals behaving alone. Much of animals’ lives are spent interacting with one another — socializing, competing and so forth — and these social behaviors are generally quite complex, as an animal must not only react to other individuals, but actively predict their future behavior. Less is understood about how brain activity might function across interacting animals. Using sophisticated recording devices, the research team set out to simultaneously monitor activity in the brains of two interacting mice, making this the first study to use the technique in two animals behaving naturally together.Related StoriesStudy provides new insight into longitudinal decline in brain network integrity associated with agingNew therapy shows promise in preventing brain damage after traumatic brain injuryNeural pathways explain the relationship between imagination and willingness to helpMETHODThe researchers attached tiny, high-tech microscopes to the heads of each mouse, which recorded activity in hundreds of individual brain cells. Fitted with the devices, the mice were placed together in pairs, first in open arenas to freely interact, and later in plastic tubes — a common method of observing competition and social hierarchy, as the dominant mouse tends to claim more of the tube’s “territory” by pushing against the subordinate mouse, or pushing it out of the tube completely.When the mice interacted with each other, their brain activity was correlated, or synced up. The more engaged they were with one another, the more coupled were their brains. This brain synchronization arose from individual cells — interestingly, some cells responded preferentially to the behavior of the self, while other cells responded only to the behavior of the social partner. The dominant mouse’s behavior tended to have more of an effect on synchronization than that of the subordinate mouse, likely because both animals in a pair are paying attention to the dominant animal.IMPACTThis is the first time that interbrain synchrony has been observed in socializing mice. Researchers believe that the insights gained from this study may shed new light on how brain activity synchronizes across humans during social interaction. Beyond adding clarity to fundamental properties of brain function in social interaction, the findings may also enable researchers to understand more about certain psychiatric and developmental disorders, including autism spectrum disorder, since many of these conditions include symptoms such as social deficits.

This EagleNosed ShovelChinned Dinosaur May Be the Weirdest Thing You See Today

first_img The lower jaw and teeth of Aquilarhinus, showing the unusual upturned end of the mandible. Credit: Photo by Albert Prieto- Marquez; material housed at the Texas Vertebrate Paleontology Collections at The University of Texas at Austin. A newfound duck-billed dinosaur species that lived about 80 million years ago had a face so bizarre that scientists named the animal “eagle-nose shovel-chin.” Its jaws resembled a pair of gardening tools, with wavy ridges along the edges in a “W” shape. An arching crest in the middle of its face was curved like the majestic beak of an eagle, giving the dinosaur’s profile the appearance of a prominent, humped nose. Scientists found the unusual fossil skull and a partial skeleton of the animal in the 1980s in Big Bend National Park, a site in southwestern Texas, though the specimen was not analyzed in detail until recently. The duck-billed weirdo shared some features in common with other duck-billed and crested dinosaurs, the group Saurolophidae, but it was more primitive, offering intriguing new clues about how the group’s trademark crests evolved, scientists reported in a new study.

In this case, the researchers couldn’t resist calling out the dinosaur’s bizarre face. The genus name “Aquilarhinus” combines the Latin word “aquila,” for “eagle,” and the Greek word “rhinos,” which means “nose.” The species name “palimentus” comes from the Latin words for “shovel” and “chin,” according to the study. All known dinosaurs in this group (also called hadrosaurids) have beak-like jaws that expand at the end into a scoop shape, “hence the nickname ‘duck-billed’ dinosaurs,” said lead study author Albert Prieto-Márquez, a researcher with the Catalan Institute of Palaeontology Miquel Crusafont in Barcelona, Spain. “However, they differ from Aquilarhinus in that this ‘scoop’ is all concave. In contrast, in Aquilarhinus, there was a rise, a convex relief at the center of the ‘scoop,'” Prieto-Márquez told Live Science in an email. That ridged, scooping chin likely came in handy millions of years ago; what is now a dry and rocky landscape in Texas was back then a coastal swamp or marsh. Aquilarhinus probably used its peculiar jaws to scoop vegetation from the bottom of a muddy creek bed, the researchers wrote. However, it’s less clear what the dinosaur’s prominent nasal crest was for, though it may have been used as a display to help the dinosaurs recognize members of their own kind and compete for mates, Prieto-Márquez said. “The crest of Aquilarhinus is simpler in structure than that of most other hadrosaurids, except members of kritosaurini (a subgroup of hadrosaurids),” he explained. “In both Aquilarhinus and kritosaurins for which the crest is known, this is just a fold of the nasal bone, giving them a Roman nose appearance.” Photos: School-Bus-Size Dinosaur Discovered in Egypt Photos: Spiky-Headed Dinosaur Found in Utah, But It Has Asian Roots Photos: Duck-Billed Dinosaurs Found in Alaska Like other hadrosaurs, or duck-billed dinosaurs, Aquilarhinus had a bony crest on its skull.

But despite the superficial similarities, Aquilarhinus proved to be a more primitive hadrosaurid than Gryposaurus, taking up a position at the very base of the group’s family tree. This hinted that the diverse shapes of hadrosaurid cranial crests all stemmed from a structure that began as a simple arched nose, Prieto-Márquez said. Aquilarhinus, aka eagle-nose shovel-chin, also provides a missing puzzle piece concerning where hadrosaurids may have originated. These dinosaurs were common across Europe, Asia, North and South America, and Antarctica during the latter part of the Cretaceous period (145.5 million to 65 million years ago), and the appearance of this primitive specimen supports an increasingly popular hypothesis that hadrosaurids first appeared in the southern part of North America, the study authors said. The findings were published online July 12 in the Journal of Systematic Palaeontology.last_img read more
