Study explores demographic socioeconomic patterns linked with use of dermatologic services

first_imgReviewed by James Ives, M.Psych. (Editor)Sep 27 2018The odds of a black or Hispanic patient visiting an outpatient dermatologist are about half that of a white patient with the same skin condition, according to a new study in JAMA Dermatology. Patients most likely to receive outpatient dermatologic services in the study were white, educated women. The findings are among several that describe disparities in the use of outpatient dermatology services.The new study includes nine years of data from 183,054 dermatology patients across the country. Researchers from Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center analyzed the data looking for demographic and socioeconomic patterns associated with use of dermatologic services.”Patients who were male, uninsured, Midwestern, insured by Medicaid/Medicare, or had a lower income or educational status were least likely to receive outpatient dermatologic care,” said the study’s first author, Raghav Tripathi, MPH, medical student at Case Western Reserve University School of Medicine. The odds of a man seeking treatment for a dermatologic condition were about two-thirds that of a woman. Across all patients, service utilization increased proportionately with education level and income.More services for certain patients meant higher costs: the per capita expenditure for white patients ($210) was approximately three times that of black ($63) or Hispanic ($73) patients. While other variables might have had an impact, ethnic disparities still persisted after the researchers controlled for education level, income, insurance status and sex. “We were surprised by the magnitude of these differences,” Tripathi said.As demographics throughout the country become more diverse, understanding disparities in how patients use health services will be integral to developing policies that increase access to care. According to the authors, recent policies under the Patient Protection and Affordable Care Act increased access to care for low-income and low-education individuals, but did not significantly improve disparities for specific ethnic groups. It also did not increase access to specialized care, like dermatology, for many demographics.Said Tripathi, “We hope our findings will encourage hospitals and dermatology clinics to consider their own quality improvement measures, designed to increase access to care among their patients. These could include interventions for minority-specific care, such as having an onsite translator, including a financial counselor in the appointment, or increasing outreach in rural areas.”Related StoriesStudy explores pregnancy-related adverse events associated with acne medicationNew e-tattoo beats conventional methods at monitoring heart healthScientists develop accurate, wearable voice recognition deviceCase Western Reserve researchers identify who is getting care and who isn’tPatients may also benefit from interventions that target specific dermatologic conditions. Half of the patients in the new study had a diagnosed dermatologic condition, yet only 36 percent of diagnosed patients sought care. Most patients diagnosed with a skin condition did not seek care at all during the nine-year study period.The least likely to seek care were patients diagnosed with chronic skin ulcers. Nine out of ten patients with chronic skin ulcers did not see a dermatologist during the study period. Chronic ulcers are a common complication of diabetes and vascular disease. Dermatologists can help recognize such ulcers and get patients into proper treatment. Without seeking care, patients may be unaware of the root causes of their skin conditions.Patients most likely to seek care in the new study were those diagnosed with non-melanoma skin cancers. Three out of four of these patients had at least one outpatient dermatologist visit during the study period. High service utilization in this population could prevent their non-melanoma lesions from turning more serious.Previous research has shown the importance of visiting a dermatologist for patients with skin conditions. Early and accurate diagnoses can improve outcomes, and stave off deadly cancers. Patients least likely to seek care, whether due to demographics or diagnosis, could be at higher risk for serious skin conditions.”Differences in utilization of outpatient dermatologists may be a key predictor for increased mortality and detriment to quality of life in different groups,” Tripathi said. “By understanding the reasons behind these differences through studies like ours, we can begin to develop population-based, targeted interventions.” Source:http://casemed.case.edu/cwrumed360/news-releases/release.cfm?news_id=1465&news_category=8last_img read more

Influenza virus can evolve resistance to experimental antiviral drug

first_imgReviewed by James Ives, M.Psych. (Editor)Oct 25 2018The influenza virus can evolve resistance to an anti-flu drug currently in development for use in pandemics but only if there are multiple genetic mutations, a study has found.Scientists at Imperial College London, in collaboration with Public Health England, have discovered that two genetic mutations would be needed for the virus to develop resistance to favipiravir, an experimental antiviral developed in Japan.Favipiravir is not currently licensed in the UK for the treatment of flu but has shown to be effective in clinical trials to date and has the potential to be used in the event of a flu pandemic where other drugs, such as Tamiflu, might fail.The researchers caution that the influenza virus has only so far been shown to develop resistance to the drug in laboratory studies, and it is unclear if the same would happen in a pandemic. However, their findings highlight a mechanism by which influenza and other viruses could potentially overcome such drugs used in the event of an outbreak and so should be closely monitored.It was previously thought that the influenza virus was unable to overcome favipiravir, with laboratory, animal and clinical studies showing little evidence of resistance. However, the latest findings, published this week in the journal PNAS, are the first to show that influenza could develop resistance to the drug.Professor Wendy Barclay, from the Department of Medicine and Action Medical Research Chair in Virology at Imperial, who led the research, said: “We’re alerting the world to the fact that RNA viruses, like influenza, can readily adapt to their environment and evolve, and that while favipiravir could be a potentially important drug in a pandemic situation, resistance can emerge.”Favipiravir acts by targeting an enzyme called RNA polymerase used by influenza to copy its genetic material. Clinical trials have shown the drug to be effective in treating flu in humans and it has also been tested against other RNA viruses, like ebola and chikungunya, which rely on the same type of enzyme to replicate, showing promise in pre-clinical trials.In the latest study, Professor Barclay and colleagues from the NIHR Health Protection Research Unit in Respiratory Infections at Imperial explored how influenza might potentially evolve to counter the drug.Related StoriesStudy finds lower risk of Type 1 diabetes in children vaccinated against ‘stomach flu’ virus‘Stomach flu’ vaccine prevents type 1 diabetes in childrenVirus employs powerful strategy to inhibit natural killer cell functionWhen influenza was grown in the presence of favipiravir in cell cultures, the virus was able to evolve, uncovering a combination of two key mutations that enabled it to become resistant to the antiviral.The first of the mutations caused a change in the RNA polymerase enzyme itself, blocking the drug’s effect, but it came at a cost for the virus and affected its ability to reproduce.However, this loss of fitness was countered by the second mutation, which restored the virus’s ability to thrive and spread.According to the researchers, it is unclear whether this combination of mutations could occur readily in viruses in the wild, but their findings are the first to show a clear genetic mechanism by which resistance to the drug could potentially come about in influenza strains around the world.They add that while their work focused on flu, other research groups have reported the same mutation in chikungunya – another RNA virus which uses the same enzyme to replicate – suggesting that there may be a general mechanism by which other RNA viruses could become resistant to the drug.”Favipiravir is still an important drug and should be in the pipeline to be used in the event we need it, but we now know that viruses can develop resistance to it,” explained Professor Barclay. “We need to look out for these mutations and monitor for them, particularly if we are using this drug in outbreak situations and in patients that might have prolonged disease, as those are conditions where you might see resistance emerging.”Dr Maria Zambon, from Public Health England, said: “We have shown that resistance can emerge to this antiviral, which has not been shown previously and we need to factor this in to our pandemic preparedness. However, pandemic planning is multifaceted and includes vaccines, antivirals and good hygiene messaging.”Professor Barclay added: “This research is a great illustration of the success of NIHR Health Protection Research Units. Not only do the findings contribute to the scientific knowledge base, they also make an important contribution to our public health knowledge about how we use these drugs and the importance of surveillance to spot the emergence of such mutations.” Source:http://www3.imperial.ac.uk/last_img read more

New shoe insole technology could help diabetic ulcers heal better while walking

first_imgReviewed by James Ives, M.Psych. (Editor)Nov 16 2018Diabetes can lead to ulcers that patients don’t even feel or notice until the sight of blood. And because ulcers can’t heal on their own, 14 to 24 percent of diabetics in the U.S. who experience them end up losing their toes, foot or leg.Purdue University researchers have developed a shoe insole that could help make the healing process more portable for the 15 percent of Americans who develop ulcers as a result of diabetes.”One of the ways to heal these wounds is by giving them oxygen,” said Babak Ziaie, Purdue professor of electrical and computer engineering. “We’ve created a system that gradually releases oxygen throughout the day so that a patient can have more mobility.”Diabetic ulcers commonly result from high blood sugar damaging nerves, which takes away feeling from the toes or feet.Without the ability to feel pain, hits and bumps tend to go unnoticed and skin tissue breaks down, forming ulcers. A lot of sugar in the bloodstream, along with dried skin as a consequence of diabetes, further slow the ulcer healing process.”We typically treat ulcers by removing devitalized tissue from the surface of the wound, and by helping the patient to find ways to take the weight off the affected foot,” said Desmond Bell, a podiatrist in wound management and amputation prevention at the Memorial Hospital in Jacksonville, Florida, and the founder of the Save a Leg, Save a Life Foundation.”The gold standard for treating an ulcer is a patient wearing a total-contact cast, which provides a protective environment for the foot. If we could test how well this insole delivers oxygen to the wound site from within the cast, then this could be a way of aiding the healing process,” he said.Purdue researchers used lasers to shape silicone-based rubber into insoles, and then create reservoirs that release oxygen only at the part of the foot where the ulcer is located.The work aligns with Purdue’s Giant Leaps celebration, acknowledging the university’s global advancements made in health, longevity and quality of life as part of Purdue’s 150th anniversary. This is one of the four themes of the yearlong celebration’s Ideas Festival, designed to showcase Purdue as an intellectual center solving real-world issues.Related StoriesSome people treated for type 1 diabetes may have monogenic diabetes, study findsDiabetes medications mask euglycemic ketoacidosis at the time of surgeryDiabetes patients experiencing empathy from PCPs have beneficial long-term clinical outcomes”Silicone is flexible and has good oxygen permeability,” said Hongjie Jiang, a postdoctoral researcher in electrical and computer engineering. “Laser machining helps us to tune that permeability and target just the wound site, which is hypoxic, rather than poison the rest of the foot with too much oxygen.”According to the team’s simulations, the insole can deliver oxygen at least eight hours a day under the pressure of someone weighing about 53-81 kilograms (117-179 pounds). But the insole can be customized to take on any weight, the researchers say.The team envisions a manufacturer sending a patient a pack of pre-filled insoles customized to his or her wound site, based on a “wound profile” obtained from a doctor’s prescription and a picture of the foot.”This is mass-customization at low cost,” said Vaibhav Jain, a recent graduate from Purdue’s mechanical engineering master’s program and a current research associate in electrical and computer engineering.Next, the researchers want to create a way to 3D print the whole insole, rather than printing a mold first and then laser-machining a pattern. They also plan to test the insole on actual diabetic ulcers, to further gauge how well they advance the healing process.”We’re wanting to bring this technology to the user by addressing whichever technicalities would be required to simplify the manufacturing flow,” Jain said.The team published its work in the September issue of the Materials Research Society Communications, a journal by Cambridge Core. Funding for this work was provided by the NextFlex PC 1.0 Project.A patent is pending on the insole technology. The team is currently seeking corporate partners.

International study increases group of lung cancer patients who may benefit from

first_img Source:https://www.cnio.es/en/news/translational-en/an-international-clinical-trial-extends-the-effectiveness-of-immunotherapy-to-more-lung-cancer-patients/ Reviewed by James Ives, M.Psych. (Editor)Dec 4 2018The strategy for triggering the patient’s own immune system to attack cancer, immunotherapy, is proving effective for more and more tumor types, although to varying degrees. In lung cancer, immunotherapy had proven to extend survival rates for only some variants of the disease. Now, an international clinical trial led by the oncologist Luis Paz-Ares, head of the Lung Cancer Clinical Research Unit H12O-CNIO at the Spanish National Cancer Research Centre (CNIO), which also encompasses professionals from the University Hospital 12 de Octubre, has substantially increased the group of lung cancer patients who may benefit from immunotherapy.The clinical trial focuses on squamous cell carcinoma, in advanced stages of the disease presenting metastasis. The results have been published in the prestigious New England Journal of Medicine (NEJM) and show that immunotherapy, when administered alongside conventional chemotherapy, “significantly increases” patient survival. For Paz-Ares, this result “offers new possibilities against a subtype of lung cancer in which, over the past two decades, the possibilities of treatment have barely advanced”.Lung cancer is the leading cause of cancer deaths worldwide. In Spain, there were over 22,000 deaths from this type of cancer in 2016 (according to data from the Spanish Society of Medical Oncology, SEOM). Squamous cell carcinoma is a type of so-called non-small-cell lung cancer; it represents between 20% and 30% of all cases of lung cancer and has a worse prognosis than other variants. In addition, it is one of the cancers for which the least amount of progress has been made in terms of treatment, because, unlike in other tumors, in this form of carcinoma, molecular targets have not been identified that would be susceptible to therapeutic exploitation -i.e., molecules essential for tumor development and progression that can be blocked with specific drugs.The results of the new study represent, therefore, a significant step forward. The authors conclude that “in patients with metastatic squamous cell carcinoma, administering the immunotherapy drug pembrolizumab along with chemotherapy (…) significantly prolongs overall and progression-free survival,” compared to when only chemotherapy is administered.Related StoriesResearchers use AI to develop early gastric cancer endoscopic diagnosis systemStudy reveals link between inflammatory diet and colorectal cancer riskBordeaux University Hospital uses 3D printing to improve kidney tumor removal surgeryPatients who received chemotherapy and immunotherapy extended their survival by almost 16 months on average, – reducing the risk of death during treatment by 36% – compared to 11.3 months for those who received chemotherapy alone.These results open the door to investigate the effectiveness of immunotherapy in patients during the early stages of the disease – without metastases- when we can prolong survival much more and even attempt to eradicate the disease, explains Paz-Ares.One very important aspect is that the combination of immuno- and chemotherapy was effective in all patients, and not only in those who showed very high levels of the protein PD-L1. Pembrolizumab acts on this protein to revitalize the body’s defense systems against the tumor. In general, this type of immunotherapy in lung cancer had only proved effective in cases where PD-L1 protein is expressed.This study corroborates the results observed in another study conducted in parallel and similar in design, but on patients with advanced non-small-cell carcinoma of non squamous cell carcinoma varieties (for example, adenocarcinoma or large cell carcinoma). In this research, a benefit was also observed when pembrolizumab was administered, which also seemed to encompass all patients, including those affected by tumors without PD-L1 expression.The challenge now, says Paz-Ares, is to find new biomarkers to help predict in which patients immunotherapy might be more effective, and also to understand why many cancers become resistant to this therapy over time. Finally, “Our intention is to find the right immunotherapy strategy for each tumor and patient, alone or in combination,” says the oncologist.last_img read more

Sausage mislabeling in Canada is down new study finds

(Editor)Feb 15 2019Sausage mislabeling in Canada is down, according to a new University of Guelph DNA barcoding study.Researchers found mislabeling and cross-species contamination of meat ingredients in 14 per cent of sausage samples selected from grocery stores across the country. That’s down from a first-ever study conducted by the same researchers over a year ago that revealed a 20-per-cent mislabeling rate.”We have reassessed the rates of mislabeling and found lower levels,” said Prof. Robert Hanner, lead author of the study. “The Canadian Food Inspection Agency (CFIA) took follow-up action after our initial study, and it appears that it had an impact.”Published in the journal Food Research International, the study involved sausage packages labeled as containing only one type of meat.The researchers used DNA barcoding along with digital PCR technology to determine which meats were in the sausage samples.”There is DNA in nearly every cell of every organism, so barcoding can be applied to products such as ground meats that would be difficult to identify with other means,” said Hanner, integrative biology professor in U of G’s Biodiversity Institute of Ontario. “In this study, barcoding was used to identify the dominant meat type in the sausage samples.””Scientific innovation helps protect Canada’s food supply on many levels, and DNA barcoding plays a key role through species identification. The CFIA applauds the University of Guelph for their research and continued dedication to advancements in science,” said the CFIA’s Deputy Chief Food Safety Officer, Dr. Aline Dimitri.Researchers tested sausages labeled as beef, chicken, pork or turkey. They also tested the samples for sheep, goat and horse.Unlike the previous study that uncovered horsemeat in one pork sausage sample, researchers found no horsemeat this time.”We decided to also include sheep and goat in this most recent study because although they may not be consumed in the same quantities as beef, chicken, pork and turkey, they are commercially raised meats that are commonly present in our food supply chain,” said Hanner.Related StoriesRaw meat can act as reservoir for bacteria associated with hospital infectionsResearchers explain how ‘viral’ agents of neurological diseases ended up in our DNAResearch sheds light on sun-induced DNA damage and repairProducts were considered contaminated when more than one per cent of another meat was detected. This ruled out trace amounts that might have resulted from incomplete cleaning of processing equipment.Of the 30 beef sausages tested, five contained sheep, four contained pork and one contained chicken.Among the 20 chicken sausages tested, three contained turkey, one contained pork and one beef. Of the turkey sausages tested, one contained chicken and one contained pork. All the pork sausages samples had only pork, meaning no cross-species contamination.Sausages labelled as single-meat but containing more than one meat type contravene food labelling regulations. Consumers may buy these products because of health issues, such as allergies, or lifestyle choices, such as avoiding pork, said Hanner.Unknown contaminants may also allow transfer of food pathogens, he added.”In certain cases, it may be of concern when there is a recall on a specific type of meat, but it is not indicated on the label.”He said it is difficult to determine whether cross-species contamination was economically motivated.”We don’t know the exact cuts of meat that were found in the samples, so we can’t determine if the contaminant meat was purposely substituted because it was a cheaper meat.”The next step would be to test throughout the supply chain to determine where mislabeling and cross-species contamination happens.”We are looking at it from the retail market and finding that there are issues,” said Hanner. “But in order to get a full understanding, we need to look at it from multiple points within the food chain.”last_img read more

Despite 1991 ruling foes of new family planning rules see law on

first_img This article was reprinted from khn.org with permission from the Henry J. Kaiser Family Foundation. Kaiser Health News, an editorially independent news service, is a program of the Kaiser Family Foundation, a nonpartisan health care policy research organization unaffiliated with Kaiser Permanente. Reviewed by James Ives, M.Psych. (Editor)Feb 28 2019State attorneys generals and women’s health advocates hoping to block in court new Trump administration rules for the federal family planning program face one major obstacle: The Supreme Court upheld very similar rules in 1991.Those rules were summarily canceled after a change in administrations. But the court is arguably more conservative than it was 28 years ago.Still, those who oppose the rules say that the ground has shifted enough to help them succeed this time. They point to protections enacted in the 2010 Affordable Care Act and changes made by Congress in the mid-1990s in funding bills for the family planning program, known as Title X.”I don’t file a lawsuit unless I’m confident we will prevail,” Washington state Attorney General Bob Ferguson said at a news conference Monday to announce his plans to sue the Trump administration over the changes to the program. “We’ve filed 17 cases against this administration,” he said. “We have not lost a case yet.”The new rules for Title X, posted Friday by the Department of Health and Human Services, are aimed primarily at evicting Planned Parenthood from the program, a longtime goal of abortion opponents. Currently no Title X money can be used for abortions, but conservative groups argue that since many Planned Parenthood affiliates receiving Title X support also provide abortions, the federal family planning money could be improperly commingled with funds used for the procedure.Planned Parenthood affiliates serve about 40 percent of the program’s 4 million patients.Specifically, the rules would forbid family planning providers in almost all cases from referring pregnant patients for abortion. It also would rescind previous regulations requiring providers to give women with unintended pregnancies “nondirective” counseling about all their options, which means that providers neither encourage nor deter women from any specific action. Women’s health advocates, including Planned Parenthood, argue that this provision would hamper physicians and other providers from giving women unbiased advice, which they say is a violation of medical ethics.The new regulations also would require any providers that also perform abortions to make those facilities physically and financially separate from their clinics that receive federal funds.Planned Parenthood has not specifically announced that it will sue, but President Leana Wen was clear last week in a call with reporters that “Planned Parenthood cannot participate in a program that would force our providers to compromise their ethics.”And several other lawsuits are being lined up in anticipation of the rules’ formal publication in the Federal Register, expected next week.The American Civil Liberties Union announced it will sue on behalf of the National Family Planning & Reproductive Health Association, which represents publicly funded family planning providers and administrators, as well as the Cedar River Clinics in Washington state. The Center for Reproductive Rights has said it will sue on behalf of family planning providers in Maine.Several other state officials have said that they will sue, including those in New York, Oregon and California.Proponents of the administration’s move point to the 1991 Supreme Court case Rust v. Sullivan as proof that the rules are constitutional. In a 5-4 decision, the court said that very similar regulations issued by the Reagan administration in 1988 were an acceptable exercise of executive authority and did not violate the underlying law or the Constitution.Related StoriesExperts release scientific statement on predicting survival for cardiac arrest survivorsFainting during pregnancy could be more serious than earlier believed finds studyPsychiatric diagnoses deemed “scientifically meaningless” by expertsAlthough the rules were upheld, subsequent legal action meant they were in effect only for a month before again being blocked and then rescinded by President Bill Clinton in 1993.”The Protect Life Rule, which the U.S. Supreme Court has upheld, will prevent organizations like the nation’s largest abortion business, Planned Parenthood, from funding their abortion activities through the Title X program,” said a statement from Alliance Defending Freedom, a law firm that opposes abortion.Opponents of the new rules, however, insist that the situation is different now. For one thing, argued several members of Congress in a letter to HHS, the department may have violated the federal Administrative Procedure Act that governs the crafting of regulations. For example, the letter said, HHS “declined to deem the Title X rule economically significant — completely disregarding the considerable health-related costs the rule would impose — and failed to conduct a comprehensive regulatory impact analysis.”And while the court is more conservative than it was in 1991, “there are two new developments; two statutes passed by Congress, that impose new requirements,” Washington Assistant Attorney General Jeff Sprung told reporters.One is language added to the spending bill that funded HHS in 1995 and was renewed in subsequent years. It restates the ban on using family planning funds for abortion, but also stipulates that “all pregnancy counseling be nondirective.”In 2010, the Affordable Care Act added to that, with language barring HHS from issuing any regulation that “interferes with communications regarding a full range of treatment options between the patient and the provider” or that “restricts the ability of health care providers to provide full disclosure of all relevant information to patients making health care decisions,” among other things.Leah Litman, an assistant professor of law at the University of California-Irvine, said the now-more-conservative Supreme Court might not necessarily accept those arguments, as well as others likely to be raised, but there is no question that “the underlying scope of [the Title X program] has changed” since 1991.last_img read more

New fluorescent sensor can detect migrating cancer cells

(Editor)May 22 2019A new fluorescent sensor developed by researchers from the University of Adelaide can detect migrating cancer cells and could be used to target medication to stop metastasis in aggressive cancers.Metastasis – the uncontrolled migration of cancer cells which creates new tumours at different locations in the body – is a major cause of cancer-related deaths.Research at the University of Adelaide has shown mammalian proteins known as ‘aquaporins’ are essential for enabling rapid migration in certain classes of aggressive cancer cells.Aquaporin-1 (AQP1) facilitates movement of water and small solutes like ions across membranes. The levels of AQP1 in cancers rise as the severity of the disease worsens.Related StoriesStudy: Nearly a quarter of low-risk thyroid cancer patients receive more treatment than necessarySugary drinks linked to cancer finds studyNew protein target for deadly ovarian cancerThe new photoswitchable ion probe was developed by University of Adelaide researchers from the Adelaide Medical School, Institute for Photonics and Advanced Sensing, and the ARC Centre of Excellence for Nanoscale BioPhotonics.It allows real-time imaging of AQP1 function in living cells as they move, creating a new capability for streamlined drug discovery for these channels using optical screening.Postdoctoral researcher Dr Victor Pei, from The Aquaporin Physiology & Drug Discovery Laboratory at The University of Adelaide, said the discovery was applicable to many types of cancer, especially aggressive types like lung, bowel and brain cancers.

Auburn study explains link between habitat loss and global emergence of infectious

first_imgThe field of disease ecology is heavily based on a hypothesis known as the dilution effect, which was released at the turn of this century. It is essentially the idea that biodiversity conservation can protect humans from emerging infectious diseases. Zohdy said the dilution effect highlights the critical role that wildlife conservation can play in protecting human health and has transformed the understanding of zoonotic infectious diseases.Related StoriesAMSBIO offers new, best-in-class CAR-T cell range for research and immunotherapyResearch sheds light on sun-induced DNA damage and repairVirus killing protein could be the real antiviral hero finds studyHowever, until now, even after a wealth of research in the past few decades has explored that hypothesis and found associations between the loss of biodiversity and EIDs, there has been no explanation for where the microbes that cause EIDs come from and how they get to humans.”Through our hypothesis, we propose that as humans alter the landscape through habitat loss, forest fragments act as islands, and the wildlife hosts and disease-causing microbes that live within them undergo rapid diversification,” Zohdy said. “Across a fragmented landscape we would then see an increase in diversity of disease-causing microbes, increasing the probability that any one of these microbes may spill over into human populations, leading to outbreaks.”Oaks said he is encouraged that the research will impact the way these problems are perceived.”Our paper introduces an evolutionary mechanism to explain the association between habitat fragmentation and disease spillover into human populations, which we hope will complement the ecological perspectives on this global health challenge,” he said.School of Forestry and Wildlife Sciences Dean Janaki Alavalapati said the paper’s findings are compelling.”Dr. Zohdy and her fellow researchers provide noteworthy insights in the field of emerging infectious diseases and the driving forces behind them,” Alavalapati said. “Their findings could result in a significant shift in the way the origins of these diseases are perceived.” Source:Auburn UniversityJournal reference:Zohdy, S. et al.

The Auburn team developed a new hypothesis, the coevolution effect, which is rooted in ecology and evolutionary biology, to explain the underlying mechanisms that drive this association.Schwartz said the team integrated ideas from multiple aspects of biology, including disease ecology, evolutionary biology and landscape genetics, to develop the new hypothesis on why diseases are more likely to spill over from wildlife to humans in deforested habitats. We provide a testable hypothesis that we hope other researchers will try to test with their data, as we will be doing.

Why buy social bots For illusion of popularity researcher says

Provided by Northeastern University On Saturday, the New York Times published an article detailing its investigation into Devumi, a company that sells Twitter followers to celebrities, influencers, and anyone else willing to pay for online popularity. The purchased followers are automated social bots—fake Twitter accounts that exist solely to boost a user’s follower count or perform simple tasks like retweeting. The Times reported that about 55,000 of these bots were found to be using photos stolen from the profiles of real people. Spotting a social bot might be harder than you think Credit: Northeastern University Citation: Why buy social bots? For ‘illusion of popularity,’ researcher says (2018, January 30) retrieved 18 July 2019 from https://phys.org/news/2018-01-social-bots-illusion-popularity.html I think those numbers are creating the illusion of popularity. This is just one of the cognitive biases affect our judgement on accounts value or usefulness. Similarly, if your tweet is favorited or retweeted by 50 bots, a real human will look at it and say, ’50 people liked it, so maybe I should also share with my network so others can like the content.’Is purchasing followers against Twitter’s rules and regulations? If so, how are Devumi and its customers getting away with it?According to Twitter’s terms of service and developer agreements, the large-scale purchasing activities shouldn’t be allowed. As a result of the Times article, the New York attorney general started an investigation of Devumi for impersonation and deception, which are illegal under the state’s law. But the problem with these accounts is they are not really active—they just boost followers. They give visibility but they don’t really act. If you look at most of the fake accounts, they either haven’t tweeted yet or they replicate other real human beings’ existing accounts.Why isn’t Twitter doing more to regulate the use of social bots?It’s hard to say. I think Twitter could easily identify and deactivate bots. They have much more information and insight about user behavior, and they have better data about tweet deletions or profile changes. Practically, it’s a relatively easy task for them to do.I think the only reason Twitter is not proactive on addressing social bots is that if they say, ‘On our platform, 15 percent of the accounts are bots,’ that looks really bad for their investors. Their business plan relies on advertisement, they charge their customers based on the number of impressions, or the number of people who will see the ad.I think there will eventually be more tools like Botometer to succeed in this arms-race with bot creators. Then the platforms will become more aware of the public’s response to exceeding number of bots wandering in their platform and engaging randomly with their followers. If people start finding that significant fraction of their followers are fake, maybe Twitter will promise to take action. Otherwise, they won’t invest on deleting accounts because it doesn’t have direct effect and what they promise to their followers is more followers, more engagement, and larger networks, so they don’t want to pay attention. Instead, they assume these are genuine interactions. Luckily, we have been observing more Twitter users have become aware of social bot problems and engaging with research community to help them improve their tools by providing feedback, reporting bot accounts, and using browser plug-ins and tools like Botometer to analyze their own followers. Explore further Twitter recently confirmed that more than 3,800 Russian troll accounts were created and deployed during the 2016 U.S. presidential election to confuse and mislead voters. As the influence of social bots becomes more apparent, Congress and consumers alike are calling for increased oversight.Onur Varol, a postdoctoral research associate at Northeastern’s Center for Complex Network Research, has been studying the problem of social bots for several years. His research, which was cited in the Times article, found that between 9 and 15 percent of active Twitter accounts are bots. Varol even created a platform—Botometer—that analyzes Twitter accounts and scores them based upon how likely they are to be bots. Here, Varol explains why social bots have become so prominent and why Twitter isn’t doing more to combat them.The New York Times article pointed out that Twitter, unlike most online platforms, doesn’t require new users to complete a spam test before signing up. Why do you think that is?I think it’s a probably a platform design choice. They don’t want to dismay people from using the platform, so they try to make it as easy and user-friendly as possible. At some point early on, Twitter made those choices and now it’s harder for them to roll back. There is email validation, which can be easily bypassed, and then recently there is mobile phone validation. But even those mobile activations can be easily dealt with by, say, creating a Google Voice number to receive confirmation SMS during account creation.If social bots are fake, does buying them really help people grow their online influence? After all, the purchased followers aren’t real people.The point is not to expect anything from the bot accounts. Bots accessible to regular users for purchase are not very sophisticated. The simple bot accounts might not help users directly to be more influential or visible, but they create a cognitive bias. If I see that you have 100 followers compared with 1,000 followers, it makes a difference. If I see you have 1,000 followers, I might think, ‘Okay, this person is sharing something really interesting. One thousand people followed her, so I should follow her, too.’ But if I see you only have 100 followers, I might think, ‘Maybe this account is not worth following.’ This document is subject to copyright.

Stop worrying about how much energy bitcoin uses

first_imgThe word “bitcoin” is as likely to garnish feverish excitement as it is glaring criticism. The financial community sees speculative promise in the form of trade that currently has little to no regulation. Meanwhile, others argue that it’s a distraction that detracts from the overall longevity of U.S. financial institutions. Credit: CC0 Public Domain This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Provided by The Conversation Indeed, this is a lot, but not exorbitant. Banking consumes an estimated 100 terrawatts of power annually. If bitcoin technology were to mature by more than 100 times its current market size, it would still equal only 2 percent of all energy consumption. Power sourcesBitcoin is certainly consuming an increasing amount of power worldwide, but is it increasing the world’s carbon consumption? Bitcoin miners have traditionally set up shop in China, where coal supplies 60 percent of the nation’s electricity. Now, bitcoin mining is exploding in areas with cheap power, like the Pacific Northwest. Power there is mainly cheap due to the massive availability of hydropower, a low-carbon resource. Bitcoin mining in China, with a largely fossil-based electricity source, may indeed be problematic. China is already one of the world’s major contributors of carbon emissions. However, bitcoin mining in Oregon? Not the same thing. Not all types of energy generation are equal in their impact on the environment, nor does the world uniformly rely on the same types of generation across states and markets. In Europe, for example, Iceland is becoming a popular place for bitcoin mining. That nation relies on nearly 100 percent renewable energy for its production. An abundant supply of geothermal and hydropower energy makes bitcoiners’ power demand cheap and nearly irrelevant.Similarly, in the hydropower-driven Pacific Northwest, miners can still expect to turn a profit without contributing heavily to carbon emissions. The right discussionLike many other aspects of the energy industry, bitcoin is not necessarily a “bad guy.” It’s simply a new, and vaguely understood, industry. The discussion about energy consumption and bitcoin is, I believe, unfair without discussing the energy intensity of new technologies overall, specifically in data centers. Rather than discussing the energy consumption of bitcoin generally, people should be discussing the carbon production of bitcoin, and understanding whether certain mining towns are adding to an already large environmental burden. Although there has been extensive discussion in the media of bitcoin’s energy consumption, I’m not aware of any studies that actually calculate the comparative carbon footprint of the bitcoin process. Global electricity consumption is going up overall. The U.S. Energy Information Administration predicts that world use will increase nearly 28 percent over the next two decades. But increasing energy consumption is bad only if we aren’t shifting toward less carbon-dense power production. So far, it seems that only miners are currently shifting toward cleaner parts of the world. So perhaps people should quit criticizing bitcoin for its energy intensity and start criticizing states and nations for still providing new industries with dirty power supplies instead. Spotlight glare on Bitcoin as numbers show mining’s energy usecenter_img Explore further Bitcoin’s energy consumption has become a recent talking point in the debate. A Forbes article published May 30 indicates that bitcoin dramatically increases global energy consumption – and that electricity is its “Achilles heel.” I am a researcher who studies clean energy technology, specifically the transition toward decarbonized energy systems. I think that the conversation around bitcoin and energy has been oversimplified. New technologies – such as data centers, computers and before them trains, planes and automobiles – are often energy-intensive. Over time, all of these have become more efficient, a natural progression of any technology: Saving energy equates to saving costs. By talking specifically about just the consumption of energy alone, I believe many fail to understand one of the most basic benefits of renewable energy systems. Electricity production can increase while still maintaining a minimal impact on the environment. Rather than focusing on how much energy bitcoin uses, the discussion should center around who indeed is producing it – and where their power comes from. Counting consumptionUnlocking a bitcoin requires an intense amount of computational power. Think of bitcoin as sort of a hidden currency code, where its value is derived by solving a programmable puzzle. Getting through this puzzle requires computer brainpower. Electricity is 90 percent of the cost to mine bitcoin. As such, bitcoin mining uses an exorbitant amount of power: somewhere between an estimated 30 terrawatt hours alone in 2017 alone. That’s as much electricity as it takes to power the entire nation of Ireland in one year.

Leading journalists join call for EU copyright reform

The plans have been firmly opposed by big US tech firms such as Google and Facebook, as well as advocates of internet freedomcenter_img European Parliament lawmakers return in September to discuss the proposal, a first draft of which was rejected last month after a fierce debate.The so-called copyright and neighbouring rights law aims to ensure that producers of creative content—whether news, music or movies—are paid fairly in a digital world.But the plans have been firmly opposed by big US tech firms such as Google and Facebook, as well as advocates of internet freedom.An open letter signed by more than 100 prominent journalists from major news outlets warned Tuesday that “this fleecing of the media of their rightful revenue” was “morally and democratically unjustifiable”.”We have become targets and our reporting missions cost more and more,” said the letter written by AFP foreign correspondent Sammy Ketz and published in several European newspapers including France’s Le Monde.”Yet, even though (the media) pay for the content and send the journalists who will risk their lives to produce a trustworthy, thorough and diverse news service, it is not they who reap the profits but the internet platforms, which help themselves without paying a cent,” the letter said.”It is as if a stranger came along and shamelessly snatched the fruits of your labour.”The editorial urged the European Parliament to “vote massively in favour of neighbouring rights for the survival of democracy and one of its most remarkable symbols: journalism”.Major publishers, including AFP, have pushed for the reform—known as Article 11—seeing it as an urgently needed solution against a backdrop of free online news that has wiped out earnings for traditional media companies.But opponents have called it a “link tax” that will stifle discourse on the Internet.Resistance has been especially heated to Article 13: the proposal to make online platforms legally liable for copyrighted material put on the web by users.Music legend Paul McCartney as well as major music labels and film studios had lobbied politicians urging them to come together and back the changes.Critics, however, argue the reform will lead to blanket censorship by tech platforms that have become an online hub for creativity, especially YouTube.They say it will also restrict the usage of memes and remixes by everyday internet surfers.But the journalists on Tuesday rejected this as a “lie”.”Free access to the web will endure because the internet giants, which now use editorial content for free, can reimburse the media without asking consumers to pay,” the open letter said.

Navy engineer gets New Years Day patent for dual mode slotted antenna

Tonn received his twenty-eighth U.S. patent, according to the U.S. Patent and Trademark Office. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Patent talk: Wireless charging using Wi-Fi routers Titled “Dual Mode Slotted Monopole Antenna,” the novel antenna design could soon be connecting your cell phone to the internet. (U.S. Patent 10,170,841)Slotted antennas are commonly used in telecommunication towers and television broadcast antennas. Unlike a standard antenna, the slots allow the antenna to be pointed in a particular direction. The Navy uses these types of antennas for radar applications and communicating with towed sonar buoys.Until now, slotted cylinder antennas have been limited by what’s called a cutoff frequency, beyond which the antenna effectively shorts out. Tonn’s work has successfully given cylinder slot antennas the ability to also act as a monopole antenna beyond the cutoff frequency by “floating” the antenna above the ground plane with a capacitor.Tonn, an expert in maritime antennas at the Naval Undersea Warfare Center, tested his design using a 12-inch copper prototype, but the patent notes that it “can be scaled to other portions of the RF spectrum, making it useful in the realm of commercial communications, e.g., digital television, cellular telephone service, etc.”Businesses that want to bring the antenna to market can now acquire it by applying for a patent license from the Navy. Under the business-friendly umbrella of technology transfer, patent license agreements allow federal laboratories to assign their intellectual property rights to a business or entrepreneur and facilitate access to inventors and technical data.TechLink, a nonprofit organization that specializes in federal technology transfer, helps companies prepare a commercialization plan and patent license application at no charge. Since 1999, TechLink has helped hundreds of companies, large and small, realize commercial success with federal inventions through the development of new and improved products and services.center_img Explore further Citation: Navy engineer gets New Year’s Day patent for dual mode slotted antenna (2019, January 4) retrieved 17 July 2019 from https://phys.org/news/2019-01-navy-year-day-patent-dual.html Provided by TechLinklast_img read more

Now, they may face imminent extinction due to climate change. In a new study published June 3 in the journal Ecosphere, researchers and volunteer scientists surveyed nearly 4,000 trees in southern California’s Joshua Tree National Park to figure out where the oldest trees tended to thrive during historic periods of extreme heat and drought. (A single Joshua tree can live up to 300 years.) Then, the researchers estimated how much of these Joshua safe zones (or “refugia”) would survive to the end of the century based on a range of climate change predictions. [Desert Green: Images of Joshua Tree National Park] The study authors found that, if greenhouse gas emissions are seriously curbed and summer temperatures are limited to an increase of 5.4 degrees Fahrenheit (3 degrees Celsius), about 19% of the park’s Joshua tree habitat would survive after the year 2070.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65953-climate-change-destroying-joshua-trees.html?jwsource=cl已复制直播00:0000:3500:35  If no action is taken to reduce carbon emissions and summer temperatures rise by 9 F (5 C) or more, however, only 0.02% of the tree’s habitat would survive to the end of the century — leaving the rare tree a hair away from extinction. “The fate of these unusual, amazing trees is in all of our hands,” lead study author Lynn Sweet, a plant ecologist at the University of California, Riverside said in a statement. “Their numbers will decline, but how much depends on us.” Survivors in the sand Joshua Tree National Park covers 1,200 square miles (3,200 square kilometers) of sandy, hilly terrain in the desert between Los Angeles, Las Vegas and Arizona. The spiny-armed Joshua trees have survived millions of years of climate ups and downs by holding on to large amounts of water to carry them through the region’s harshest droughts. However, the study authors wrote, young Joshua trees and seedlings aren’t able to store enough water to weather these dry spells. During long droughts — such as the epic, 376-week-long one that lasted from December 2011 to March 2019 in California — various parts of the park became too parched to support young Joshua tree growth, preventing the species from reproducing properly. As global temperatures rise, more and longer droughts are expected to occur around the world, and that means fewer and fewer new Joshua trees surviving to adulthood. To find out which parts of the tree’s desert habitat were safest and which were most at risk of drying up, a team of park researchers and volunteers counted thousands of trees in various parts of the park, noting each tree’s height (which helped predict the tree’s age) and the number of new sprouts in the area. They found that, in general, trees growing in higher-elevation spots, which tend to be cooler and retain more moisture, survived much better than those in lower, drier regions. The team compared these survey results with historic climate records to predict how much of the Joshua tree’s habitat was likely to shrink as temperatures rise and rainfall decreases over the rest of the century. Under the best-case scenario, they found, just 1 in 5 Joshua trees will survive the next 50 years. Taking swift action to reduce greenhouse gas emissions is the only way to save the Joshua trees from extinction, the researchers found. However, even trees in the best-hydrated habitats will still face a serious threat from wildfires, which have also been occurring with greater frequency and intensity as the climate warms, they said. According to the researchers, fewer than 10% of Joshua trees survive when wildfires rush through their habitats — thanks, in part, to car exhaust coating desert shrubs with flammable nitrogen. This, at least, is a threat that can be addressed on a local level, right now. “Fires are just as much a threat to the trees as climate change, and removing grasses is a way park rangers are helping to protect the area today,” Sweet said. “By protecting the trees, they’re protecting a host of other native insects and animals that depend on them as well.”last_img read more
