FANS BEG JUSTIN BIEBER TO CANCEL HIS CONCERT IN THE WAKE OF THE MANCHESTER ATTACKS
By Alex Riccardi - Yesterday at 4:23 pm

    No one should have to live in fear but right now, in the wake of the Manchester attacks, some teens and young adults are scared. And you have a good reason. Bombs went off just minutes after Ariana Grande's performance in England taking the lives of 22 people and injuring many others. But, it's important to remember that concert venues and staff try to do everything they can to keep the audience members safe.

    Ariana has officially postponed her "Dangerous Woman" until at least the beginning of June, however, there's no telling if she will cancel more shows after that. In the wake of all of this, fans are encouraging Justin Bieber to pull out of his performances in the U.K. The "Sorry" singer is set to headline at the British Summertime Festival on July 2nd. But, fans don't think it's a good idea.

    They have been expressing their concern on social media and even starting the trend, #nopurposetour. One fan wrote, "@scooterbraun please. We're so worried about Justin's Security.... please please cancel Justin's purpose tour #NoPurposeTour." Another fan said, "Justin, please cancel Purpose Tour, we want you to be safe, we want you alive! We love you! #prayersforManchester #NoPurposeTour." This is absolutely heartbreaking. A third Belieber wrote, "#NoPurposeTourUK @justinbieber I don't want you to die, please do something."

    Justin nor his manager Scooter Braun have yet to comment on the whole thing. However, we also must note that Scooter is Ariana's manager too. He definitely has his clients' best interest and their safety in mind. Now that Ariana has canceled some of her upcoming shows, Scooter definitely had a role in that decision. While fans may be scared for Justin, we have a feeling he is in good hands. If there was any chance of a threat or immediate danger, he wouldn't do the performance. However, the music can't be stopped because of evil in this world. Katy Perry, The Chainsmokers, and Lorde have all vowed to continue doing their upcoming shows in the wake of this tragedy.

  The UN Refugee Agency’s annual Global Trends study found that 65.6 million people were forcibly displaced worldwide at the end of 2016 – a total bigger than the population of the United Kingdom and about 300,000 more than last year.

  It noted that the pace at which people are becoming displaced remains very high. On average, 20 people were driven from their homes every minute last year, or one every three seconds.

  In each of the past five years, annual increases to the global displacement total have been in the millions. While the 2016 total is high – representing an enormous number of people needing protection worldwide – it also shows that growth in displacement slowed last year.

  The total figure includes 40.3 million people uprooted within the borders of their own countries, about 500,000 fewer than in 2015. Meanwhile, the total number seeking asylum globally was 2.8 million.

  However, the total seeking safety across international borders as refugees topped 22.5 million, the highest number seen since UNHCR was founded in 1950 in the aftermath of the Second World War.

  The conflict in Syria, was the world’s biggest producer of refugees (5.5 million). However in 2016 the biggest new factor was South Sudan, where the disastrous break-off of peace efforts in July of that year contributed to an outflow of 737,400 people by the end of the year. That number has continued to rise during the first half of 2017.

  Nyawet Tut, a South Sudanese mother of five in her 30s, described the situation:

  “My husband was killed in the war which, in addition to the shortage of food, made me decide to leave my home, everything, behind,” she told UNHCR staff during an interview at a temporary way station in Ethiopia.

  In terms of overall displacement, Syria still accounts for the biggest numbers, with 12 million people (65 per cent of the population) displaced internally or living outside the country as refugees.

  Particularly heartbreaking is the plight of children, who make up half the world’s refugees, and continue to bear a disproportionate burden of the suffering, mainly because of their heightened vulnerability.

  Tragically, 75,000 asylum claims were received from children travelling alone or separated from their parents, among them youngsters like Tareq, 16, who dodged armed combatants to walk out of Syria into neighbouring Turkey.

  “There was no future where we lived”, he told UNHCR. “There was no university and no work. There were troops grabbing young children like me, and they send them to war, and they get killed. I wanted to study”.

  Last year, much of the news coverage focused on refugee resettlement to developed countries, including efforts by some states to restrict access and even erect border barriers.

  However, figures in the report showed that, worldwide, most refugees – 84 per cent – were in developing or middle-income countries at the end of 2016, with one in every three (4.9 million people) being hosted by the world’s least developed countries.

  This huge imbalance reflects several things including the lack of consensus internationally when it comes to hosting refugees, and the proximity of many poor countries to regions of conflict.

  It also illustrates the need for countries and communities supporting refugees and other displaced people to be properly resourced and supported, the absence of which can cause instability, have consequences for life-saving humanitarian work or lead to secondary displacement.

TEXTO:

  Despite its fearsome, Velociraptor-like skull, a

161-million-year-old dinosaur the size of a duck would

have been a shining, shimmering and splendid sight to

behold — mostly because it sported gleaming,

[5] iridescent feathers that were rainbow-colored, a new

study finds. Iridescent feathers glistened on the

dinosaur’s head, wings and tail, according to an analysis

of the shape and structure of the creature’s

melanosomes, the parts of cells that contain pigment.

[10] “The preservation of this dinosaur is incredible — we

were really excited when we realized the level of detail

we were able to see on the feathers,” study co-

researcher Chad Eliason, said.

  After discovering its iridescence and noting the

[15] unique bony crest on top of the dinosaur’s head,

researchers gave it a colorful name — Caihong juji —

which is Mandarin for “rainbow with the big crest.” C.

juji isn’t the first dinosaur on record to have iridescent

feathers; Microraptor, a four-winged dinosaur also

[20] sported gleaming feathers. But that dinosaur lived about

40 million years after C. juji, so the newly identified

dinosaur is by far the oldest dinosaur on record to flaunt

iridescent plumage, the researchers said.

  C. juji is also the oldest animal on record to

[25] have asymmetrical feathers, which help modern birds

steer while flying. However, unlike modern birds, whose

asymmetrical feathers are on their wing tips, C.

juji sported these lopsided feathers on its tail. That,

combined with the fact that C. juji likely couldn’t fly, led

[30] ’the researchers to conclude the dinosaur likely used its

feathers to attract mates and keep warm. This “bizarre”

feature has never been seen before in either dinosaurs

or birds, which evolved from dinosaurs, said study co-

researcher Xing Xu.

New treatment can ‘halt’ multiple sclerosis, says study
June 10, 2016.

   In Multiple Sclerosis (MS) the protective layer surrounding nerve fibres in the brain and spinal cord – known as myelin – becomes damaged. The immune system mistakenly attacks the myelin, causing scarring or sclerosis. The damaged myelin disrupts the nerve signals – rather like the short circuit caused by a frayed electrical cable. If the process of inflammation and scarring is not treated then eventually the condition can cause permanent neurodegeneration.
   Aggressive chemotherapy followed by a stem cell transplant can halt the progression of multiple sclerosis, a small study has suggested. The research, published in The Lancet, looked at 24 patients aged between 18 and 50 from three hospitals in Canada. For 23 patients the treatment greatly reduced the onset of the disease, but in one case a person died. An MS Society spokeswoman said this type of treatment does “offer hope” but also comes with “significant risks”.
    Around 100,000 people in the UK have MS, which is an incurable neurological disease. Most patients are diagnosed in their 20s and 30s. One existing treatment is for the immune system to be suppressed with chemotherapy and then stem cells are introduced to the patient’s bloodstream – this procedure is known as an autologous haematopoietic stem cell transplant (HSCT).
    But in this study, Canadian researchers went further – not just suppressing the immune system, but destroying it altogether. It is then rebuilt with stem cells harvested from the patient’s own blood which are at such an early stage; they have yet not developed the flaws that trigger MS. The authors said that among the survivors, over a period of up to 13 years, there were no relapses and no new detectable disease activity.
   All the patients who took part in the trial had a “poor prognosis” and had previously undergone standard immunosuppressive therapy which had not controlled the MS – which affects around two million people worldwide. One person died as a result of the strong effects of the chemotherapy, the authors said.
    Lead author Dr. Mark Freedman admitted there were limitations to the study – such as the small sample size – and there was no control group used for comparison with those who were treated. He said: “Larger clinical trials will be important to confirm these results. Since this is an aggressive treatment, the potential benefits should be weighed against the risks of serious complications associated with HSCT and this treatment should only be offered in specialist centres experienced both in multiple sclerosis treatment and stem cell therapy, or as part of a clinical trial.”
    Dr. Emma Gray, who is head of clinical trials at the MS Society, said: “This type of stem cell transplantation is a rapidly evolving area of MS research that holds a lot of promise for people with certain types of MS. This treatment does offer hope, but it’s also an aggressive procedure that comes with substantial risks and requires specialist aftercare. If anyone is considering HSCT we’d recommend they speak to their neurologist.”

    Prof. Siddharthan Chandran at the University of Edinburgh described the work as “important and carefully conducted. It demonstrates that powerful chemotherapy-based treatment for a selected subset of MS patients with a very aggressive disease is effective in preventing further disabling relapses and, in a proportion, appears to render them effectively disease-free,” he said.
   Meanwhile, Dr. Stephen Minger, a stem cell biologist and independent consultant, described the study as “truly impressive”. He said: “It’s important to stress that this is a very early study, though with impressive long-term follow-up of treated patients. Nevertheless, the clinical results are truly impressive, in some cases close to being curative, though we need longer-term follow-up to know for certain whether the patients continue to do well or if there is a chance of relapse.”
