Your body’s superpowers

The remarkable abilities already inside us.

Norovirus might have laid you low for a short while, but you’re recovering, aren’t you? Your immune system is to die for. Researchers are still getting to grips with how it works but at every turn it has thrown out marvellous surprises. In the early days of vaccination against tuberculosis, for example, it was noted that it protected you not only from TB, but a host of other diseases, too.

We still don’t know why; it’s clear that we have yet to understand the full power of the human immune system. Just in December, for instance, we learned that the system’s T-cells, which fight viruses and bacteria, are not all created equal. Almost all of our knowledge of human T-cells has come from blood samples. But research using T-cells harvested from the organs of New York cadavers has shown that each region of the body has its own particular way of fighting invaders. Columbia University’s Donna Farber, who led the study, believes this discovery may open up the path to tightly focused vaccines that can activate the most appropriate of the body’s immune responses.

Her optimism is supported by another surprise the immune system has just delivered. New Scientist reported this month that there is now hope for a vaccine against age-related macular degeneration (AMD), an incurable condition that blinds millions of people around the world.

AMD comes from the build-up of proteins and other debris on the retina. In healthy people this is cleared away by specialist cells. Those cells stop working in people with AMD. This appears to have two consequences: the build-up of debris continues and the light-sensitive cells of the retina beneath the debris start to die off. The result is a slowly widening black hole at the centre of your field of vision.

Pioneering treatments with a laser can stimulate the nonfunctioning cells to get them going again, which is exactly what Robyn Guymer of the University of Melbourne was trying to do in his trial on 50 patients. The idea was to try the laser treatment in one eye and leave the other eye as a control. Then tests on each eye would show what improvements the procedure could give.

So, you could imagine it was a little frustrating that in the tests the lasered eye didn’t seem to be that much better than the one that had been left alone. But Guymer soon realised this was because the vision of the untreated eye had also improved. The laser surgery had stimulated the patients’ immune system to respond to alarm calls from the eye.

Your eyes are usually offlimits to your immune system. It seems a sensible evolutionary trick, because the immune system’s standard response causes inflammation, which could be catastrophic in an instrument as sensitive as the eye. However, the cells destroyed by the laser appear to send out a signal so loud that the immune system overrides the safety mechanism and sends in the troops – to both eyes – to restore order.

There is now hope that AMD can be treated with a routine procedure at a very early stage, and that those most at risk of developing it can have their immune systems stimulated before the symptoms appear. But there is a wider lesson: with various successes in vaccines against cancer – particularly colon cancer – looking likely in the next few years, it’s becoming clear that the most profitable path for medicine might be to explore partnerships with the remarkable abilities that already lie within us.

Clickbaiting terror: what it’s like to write viral news after a tragedy

Does the viral news cycle callously capitalise on terrorism, or is it allowing a different audience to access important news and facts?

On a normal day, Alex* will write anywhere between five to ten articles. As a content creator for a large viral news site, they [Alex is speaking under the condition of strict anonymity, meaning their gender will remain unidentified] will churn out multiple 500-word stories on adorable animals, optical illusions, and sex. “People always want to read about sexuality, numbers of sexual partners, porn habits and orgasms,” says Alex. “What is important is making the content easily-digestible and engaging.”

Alex is so proficient at knowing which articles will perform well that they frequently “seek stories that fit a certain template”. Though the word “clickbait” conjures up images of cute cat capers, Alex says political stories that “pander to prejudices” generate a large number of page views for the site. Many viral writers know how to tap into such stories so their takes are shared widely – which explains the remarkably similar headlines atop many internet articles. “This will restore your faith in humanity,” could be one; “This one weird trick will change your life…” another. The most cliché example of this is now so widely mocked that it has fallen out of favour:

You’ll never believe what happened next.

When the world stops because of a tragedy, viral newsrooms don’t. After a terrorist attack such as this week’s Manchester Arena bombing, internet media sites do away with their usual stories. One day, their homepages will be filled with traditional clickbait (“Mum Sickened After Discovery Inside Her Daughter’s Easter Egg”, “This Man’s Blackhead Removal Technique Is A Complete And Utter Gamechanger”) and the next, their clickbait has taken a remarkably more tragic tone (“New Footage Shows Moment Explosion Took Place Inside Manchester Arena”, “Nicki Minaj, Rihanna, Bruno Mars and More React to the Manchester Bombing”).

“When a terrorist event occurs, there’s an initial vacuum for viral news,” explains Alex. Instead of getting reporters on the scene or ringing press officers like a traditional newsroom, Alex says viral news is “conversation-driven” – meaning much of it regurgitates what is said on social media. This can lead to false stories spreading. On Tuesday, multiple viral outlets reported – based on Facebook posts and tweets – that over 50 accompanied children had been led to a nearby Holiday Inn. When BuzzFeed attempted to verify this, a spokesperson for the hotel chain denied the claim.

Yet BuzzFeed is the perfect proof that viral news and serious news can coexist under the same roof. Originally famed for its clickable content, the website is now home to a serious and prominent team of investigative journalists. Yet the site has different journalists on different beats, so that someone writes about politics and someone else about lifestyle or food.

Other organisations have a different approach. Sam* works at another large viral site (not Buzzfeed) where they are responsible for writing across topics; they explains how this works:  

“One minute you're doing something about a tweet a footballer did, the next it's the trailer for a new movie, and then bam, there's a general election being called and you have to jump on it,” they say.

Yet Sam is confident that they cover tragedy correctly. Though they feel viral news previously used to disingenuously “profiteer” off terrorism with loosely related image posts, they say their current outlet works hard to cover tragic news. “It’s not a race to generate traffic,” they say, “We won't post content that we think would generate traffic while people are grieving and in a state of shock, and we're not going to clickbait the headlines to try and manipulate it into that for obvious reasons.”

Sam goes as far as to say that their viral site in fact has higher editorial standards than “some of the big papers”. Those who might find themselves disturbed to see today’s explosions alongside yesterday’s cats will do well to remember that “traditional” journalists do not always have a great reputation for covering tragedy.

At 12pm on Tuesday, Daniel Hett tweeted that over 50 journalists had contacted him since he had posted on the site that his brother, Martyn, was missing after the Manchester attack. Hett claimed two journalists had found his personal mobile phone number, and he uploaded an image of a note a Telegraph reporter had posted through his letterbox. “This cunt found my house. I still don't know if my brother is alive,” read the accompanying caption. Tragically it turned out that Martyn was among the bomber's victims.

Long-established newspapers and magazines can clearly behave just as poorly as any newly formed media company. But although they might not always follow the rules, traditional newspapers do have them. Many writers for viral news sites have no formal ethical or journalistic training, with little guidance provided by their companies, which can cause problems when tragic news breaks.

It remains to be seen whether self-policing will be enough. Though false news has been spread, many of this week’s terror-focused viral news stories do shed light on missing people or raise awareness of how people can donate blood. Many viral news sites also have gigantic Facebook followings that far outstrip those of daily newspapers – meaning they can reach more people. In this way, Sam feels their work is important. Alex, however, is less optimistic.

“My personal view is that viral news does very little to inform people at times like this and that trending reporters probably end up feeling very small about their jobs,” says Alex. “You feel limited by the scope of your flippant style and by what the public is interested in.

“You can end up feeding the most divisive impulses of an angry public if you aren’t careful about what conversations you’re prompting. People switch onto the news around events like this and traffic rises, but ironically it’s probably when trending reporters go most into their shells and into well-worn story formats. It’s not really our time or place, and to try and make it so feels childish.”
