    This could solve the shortage of available eye donors and help millions of blind people gain sight again.

    In a first, scientists have created 3D printed human corneas that could solve the shortage of available eye donors and help millions of blind people gain sight again.

    As the outermost layer of the human eye, the cornea has an important role in focusing vision. Yet there is a significant shortage of corneas available to transplant, with 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder.

    In addition, almost 5 million people suffer total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease. The proof-of-concept research, published in the journal Experimental Eye Research, shows how stem cells from a healthy donor cornea were mixed together with alginate and collagen to create a solution that could be printed, a ‘bio-ink’

    Pope Francis Is Beloved. His Papacy Might Be a Disaster.


    Bruce Kirkpatrick
    The New York Times

    ·

    Here is a look at the state of the Catholic, Orthodox, Episcopal, and a bit of Protestantism among each other, and how this author views the effect Pope Frances is having. . Certainly, few will accept entirely his views, but it gives me and others a different insight into this Christian world. Worth reading. Rare for the NY Times.

    The conversation has become predictable. A friendly acquaintance — a neighbor, a fellow parent, our real estate agent — asks about my work. I say I’ve been writing a book about the pope, and the acquaintance smiles and nods and says “Isn’t he so wonderful?” or, “That must be an inspiring thing,” or, “I have a friend who would love to read it.” And then eventually I find myself saying, uncomfortably, “Well, they should know that it’s not entirely favorable.”

    A pause, puzzled and slightly crestfallen. “But you’re writing about the nice pope?”

    The consistency of these exchanges is a testament to the great achievement of Pope Francis’ five years on the papal throne. He leads a church that spent the prior decade embroiled in a grisly sex abuse scandal, occupies an office often regarded as a medieval relic, and operates in a media environment in which traditional religion generally, and Roman Catholicism especially, are often covered with a mix of cluelessness and malice.

    And yet in a remarkably short amount of time — from the first days after his election, really — the former Jorge Bergoglio has made his pontificate a vessel for religious hopes that many of his admirers didn’t realize or remember that they had.

    Some of this admiration reflects the specific controversies he’s stirred within the church, the theological risks he’s taken in pushing for changes that liberal Westerners tend to assume Catholicism must eventually accept — shifts on sexual morality above all, plus a general liberalization in the hierarchy and the church.

    It’s OK to shoot down drones says Swiss Legal experts


    ‘It’s OK to shoot down drones’ say Swiss legal experts (but only Swiss drones?)

    If a drone is invading your personal privacy you are entitled to shoot it down and aren’t liable for damages, according to new findings by Swiss lawyers.

    Drones are increasingly popular with private individuals in Switzerland for recreational use and to take aerial videos.

    But the remote-controlled craft can also be used by for spying on individuals or taking unauthorized photos – for example of people sunbathing on their balcony.

    Until now legal opinion has held that victims of drone surveillance cannot defend themselves.

    But Basel lawyers Jascha Schneider-Marfels and Sebastian Kaufmann say that according to their interpretation of the law, people who are being spied upon by drones are justified in shooting them down, 20 Minuten reported.

    “A drone pilot who goes against the law by invading people’s personal privacy can expect that the person affected will defend themselves – whether with a high pressure water jet or a net gun,” Schneider-Marfels told the paper.

    If a private detective uses a drone to spy on an adulterous couple or a jilted lover takes topless photos of his ex on her balcony this constitutes an attack on the personal sphere in which case self-defence is justified, the lawyer said.

    There would be no liability for damage caused to the drone.

    “Personal rights outweigh property protection rights in such cases,” Schneider-Marfels said.

    But a drone must not be brought down where injury could be inflicted to people in the area, he said.

    In February a company in the south-eastern canton of Graubünden unveiled a net gun designed to bring down small drones. 

    The compact defensive weapon which resembles a pistol fitted with a large silencer has a guaranteed range of up to 30 meters and operates by “shooting” nets that entrap drones, bringing them to the ground.

    Also in February, police in Geneva said they were training two eagles to take down rogue drones.

    The plan is for the eagles to be fully operational by the end of the year.

    Sweden Plans to Ban All Religious Schools


    After lax immigration policies have enabled a flood of Muslim immigrants from war-torn countries such as Syria and Iran to take up refuge in Sweden, the European country must now contend with several troubling issues.

    Among those is the rise of Muslim schools in Sweden who are engaging in acts such as segregating male and female students on the bus and in the school. Instead of speaking out against these specific incidents, Swedish officials have instead moved to ban religious schools entirely.

    Thanks to this new policy, 70 religious schools must now close their doors. This includes 59 Christian schools and 11 Muslim schools. What’s worth noting is the fact that one religious school in Sweden – its sole Jewish school – will be allowed to remain open for the reason that Muslim students refuse to integrate with Jewish students, and having a Jewish school still in place will prevent Muslim-Jewish integration from becoming an issue.

    The way in which Sweden is handling the problems posed by certain Muslim schools is sickening. For 1,000 years, religious schools have existed in Sweden. Now, they are being forced to close their doors for good.

    Sweden officials believe that they have a problem with religion, when in reality it is a problem with immigration that is to blame for the issues they are facing.

    For more information on why Sweden is banning religious schools, be sure to check out the video below.

    90% of Chinese transgenders threatened and insulted, received ‘therapy’: survey

    90% of Chinese transgenders threatened and insulted, received ‘therapy’: survey

    (Global Times)    08:32, March 29, 2018

    Transgender people in China are not well-received by their families, and 83 percent of respondents of a survey said they were abused by their parents.

    The survey, published by Guangzhou-based NGO Trans Center and sent to the Global Times on Wednesday, includes 113 transgender respondents from 21 provinces, municipalities and cities in China.

    Eighty-three of those surveyed said they were abused by their parents, some by other relatives such as grandparents, uncles and siblings, the survey shows.

    Nearly half of the respondents were between 19 and 26 years old.

    A transgender woman, who requested anonymity, told the center that her parents not only verbally abused her, but also threatened to kill her, or kicked her out when she had no income at all, and was forced to shave her hair and nails.

    The survey shows almost 90 percent of transgender people were threatened or insulted by others and received “therapy” to “cure” them. About 1 percent were even forced to have sex with others.

    The 2017 Chinese Transgender Population General Survey Report released by the Beijing LBGT Center also found that while most transgender people would like to receive hormone therapy or sex reassignment surgery (SRS), they cannot, and around 71 percent said that safe, reliable hormone therapy or drugs are difficult to get. Many of those who would like to get SRS, around 89 percent, said they could not because of economic conditions and parents’ attitude.

    It is hard to officially ban LGBT conversion therapy as many people in China still believe sexual minorities are sick, Peng Xiaohui, a sexologist at Central China Normal University in Wuhan, Hubei Province, told the Global Times.

    He suggested the group should continue to campaign and provide psychological and legal help to those people.

    The organization said that an anti-domestic violence law is urgently needed for transgender groups, because most of them are being abused by their parents, while the current anti-domestic violence law focuses on couples.

    The world’s most impactful scientific researchers


    Clarivate Analytics names the world’s most impactful scientific researchers with the release of the 2017 Highly Cited Researchers List

    The rise of China in publication output and influence demonstrates a dramatic development

    Clarivate Analytics

    Nov 15, 2017, 00:01 ET


    PHILADELPHIA, Nov. 15, 2017 /PRNewswire/ — Clarivate Analytics, the global leader in providing trusted insights and analytics to enable researchers to accelerate discovery, today released its publication of its annual Highly Cited Researchers list.  The citation analysis identifies the most frequently cited researchers as determined by the extent to which their papers have supported, influenced, inspired and challenged other researchers around the globe. It identifies authors who have consistently won peer approval from international researchers in the form of high citation counts.

    For more than two decades the Web of Science has served as the basis for regular listings of researchers whose work is cited at a level markedly higher than average for their fields. Clarivate Analytics now presents the latest updates to these listings: the extensive roster of 2017’s Highly Cited Researchers, based on work published and cited over the last decade.

    Key findings show:

    • More than 3,300 Highly Cited Researchers in 21 fields of the sciences and social sciences. 130,000 papers aligned to 900 institutions were selected this year.
    • The USA fields the highest number of authors, at 1,661, a 13% increase on the 2016 listing. The UK ranks second with almost 350 entries.
    • China is gaining fast, in third place, with the highest increase of any nation, showing a 34% jump to 237 authors.
    • Several authors -147 in fact – are credited for Highly Cited Papers in more than one field of research.  Twenty authors appear in three fields.
    • Finland (25%) & Singapore (21%), whilst their respective overall totals of authors listed are <30, also posted notable percentage increases since 2016.
    • In terms of notable institutions on the list:
    1. Harvard University, USA tops the institutional table with 109 entries, followed by,
    2. Stanford University, USA  has 64
    3. Germany’s Max Planck Society, lists 47 authors
    4. The Chinese Academy of Science boasts 45 entries

    The two-part study also spotlights a ranking of Hot Papers that quickly accumulate a high number of citations soon after publication. The list of emerging research trends features 21 researchers who, since 2014, have each published at least 14 Hot Papers, according to citations tallied as of December 2016.

    Michael Grätzel of the Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland and Henry J. Snaith of Oxford University, UK share the top spot with 29 Hot Papers for multiple fields of research.

    “The rise of China in publication output and world share in internationally influential journals indexed in the Web of Science has been a dramatic development during the last 20 years,” notes David Pendlebury, Senior Citations Analyst at Clarivate Analytics. “What we are now seeing is China’s increasing presence among most cited authors and papers, especially in the physical sciences. This year, the number of Chinese scientists in the Highly Cited Researchers list is 237, 34% more than last year. That makes the nation third in number of highly cited researchers behind the USA and UK. China’s output of materials science papers is now more than twice that of the United States, and it is capturing a greater and greater share of top cited papers in the field. In some fields China has not only caught up, but it is now powering ahead.”

    The methodology that determines the who’s who of researchers draws on the data and analysis performed by bibliometric experts from Clarivate Analytics.  It uses Essential Science Indicators, a unique compilation of science performance metrics and trend data based on scholarly paper publication counts and citation data from the Web of Science, the premier web-based environment of scientific and scholarly research literature totaling over 33,000 journals.
