Goodbye Swipe Cards, Hello Microchips Embedded in the Skin?

As with almost all technology in our lives, as soon as we get used to something and how it works, a shinier, brand-new replacement comes out. The same can be said for swipe cards: we use them to get on buses, gain entry into our workplaces, buy our lunch... You get the picture. But an office complex in Sweden, called Epicenter, is taking it all to the next level with a chip embedded under the skin, between the thumb and forefinger. And implantation only has the fleeting sharpness of an injection because of the tiny size of the RFID chip (RFID stands for radio-frequency identification), only about the size of a grain of rice. Epicenter will become home to a number of companies, with the chip ultimately being offered to the 400 or so people who will be working within its hi-tech walls. To gain entry to the building, all these people will have to do is hold their hand against the main front door. The same can be done to gain access to their own office space. Even the smallest of tasks, such as operating the photocopier, simply involves waving their hand over the machine. And the further along the line, the more perks there will be for having the chip, such as being able to pay for items in the cafe with just the touch of their hand. The building has been built by AMF Fastigheter, a property company in Sweden. Epicenter has also been described as an innovation hub and workplace collective for members only. And innovative is certainly the word. The whole building is run on the internet, with the building and facilities management being run through Microsoft's "Internet of Things" (IoT). In fact, you won't be surprised to learn that Microsoft is a member of AMF Fastigheter! Emptying a meeting room or notifying someone that a plant needs to be watered might seem like some of the most insignificant notifications. But all of these things are connected through sensors and appliances and nothing gets left out. Just think: no more having to remember so many different pin numbers or passwords. No more frantic search for the swipe card that has inevitably pushed itself into the far recesses of your bag (even though you remember putting it in your purse...). No more having to fumble through a keychain holding what seems like a thousand different keys. "Today, it's a bit messy," said Hannes Sjoblad, one of Epicenter's organisers. "Wouldn't it be easy to just touch with your hand? That's really intuitive."

Learning to Love Yourself

Can you remember the last time you treated yourself and actually felt like you deserved it? Or - no matter how silly it sounds - when the last time said, "I love you" to yourself? You might think it sounds a little silly, but according a website called Happify, we can make ourselves happier. And we would be a lot better off if we started treating ourselves with the same amount of love and respect that we give our friends and family. Happify is dedicated to helping people create their own happiness and say that the best first step you can take is by learning to love yourself and building on your self-worth. The website cites previous studies that have shown that people, who have taught themselves the art of self-compassion, are actually more capable of feeling joy. Not only that, but these people have also been shown to be more optimistic and grateful, too. The website recommends activities for the user to participate in every day, but these are tailored to the user. This means that the activities will yield the best results suited for the user's goals. And the user will also be able to learn valuable skills to feel more peace of mind, as well as more engaged, motivated and excited about the future. Self-compassion, as defined by the website, involves being gentle and supportive of oneself, remembering that everyone makes mistakes (it's what makes them human) and being aware of your own suffering. But why do the people at Happify think we need to work on our self-compassion? Firstly, there is the matter that a lot of people out there feel that their life would be better if only they could just be better themselves. We tend to confuse self-compassion with narcissism, self-pity, self-indulgence and making excuses for bad behaviour. But, in fact, self-compassion involves us taking responsibility for our behaviour, even when that behaviour is bad, and accepting ourselves as a person. If we are able to take responsibility for ourselves, it gives us the chance to change our behaviour, so we can progress forward towards achieving our goals. Happify explains that being able to love oneself also allows us to be more compassionate to other people - if you can forgive yourself, you are better able to forgive other people. Embracing who you are without being self-critical about it lowers the risk of you suffering from stress, depression or other mental illnesses. It also enables people to implement better coping strategies, should we find ourselves taking a self backwards.

Boy Gets Best Birthday Present Ever!

There are some things we become really passionate about that other people just don't 'get' - perhaps something you got into when you were a child that you just never laid down. Dylan Johnson, from Virginia in the US, is like that. Ever since he was two years old, he has been fascinated with vacuum cleaners. He loves seeing how they work, what they can do, and he even has a favourite brand: the Kirby. Even now, as a teenager who has just celebrated his 14th birthday, spends nearly every waking moment thinking or talking about Kirby vacuum cleaners.Dylan, who has autism, loves vacuum cleaner so much that he even used to dress up as a door-to-door salesperson when he was younger. With his most recent birthday fast approaching, Dylan's mum, Jodie Greene wanted to do something awesome for her son. She had already arranged for him to have a special vacuum-themed cake, but knew that if she wanted Dylan to truly enjoy his birthday, she would have to get her thinking cap on. And then she had an amazing idea! Jodie decided to contact Kirby via email. "I'm reaching out to you in hopes for an answer to an unusual request for my son who is autistic," she opened with. She explained about Dylan's fascination with vacuum cleaners and that his favourite brand was their very own Kirby. She didn't want to buy an actual vacuum cleaner for her son because they can cost $400 (£260) and up. What Jodie was hoping for was to pay a flat fee for a demonstration to be carried out by a Kirby salesperson, perhaps even a trainee. "I do not want anything free," she added, "but as the mother of a special-needs child, it is so hard to find things to make my son happy." Kirby didn't send a trainee, and they didn't charge her. Instead, they sent some Kirby branded goods (a football/soccer ball, t-shirt and hat) and passed along the email to Al Archie, who lived in the same area as Dylan and Jodie. Al had been selling Kirby vacuum cleaners for 25 years, a real veteran. He turned up to the house on Dylan's birthday, and the teenager was obviously overjoyed at his birthday present. "He knew more about Kirby that I did!" exclaimed Al. "I have never experienced anything like that." He added that Dylan made him feel like a celebrity sports star meeting his fans. Al presented Dylan with his very own Kirby vacuum cleaner.And when the demonstration was over, the birthday surprise didn't stop there! He says that Dylan made him feel how Michael Jordan must feel when fans get to meet him. The company also gave him a Kirby branded soccer ball, hat and T-shirt. "I got a Kirby vacuum," said Dylan. "My best birthday present ever!"

MPs Vote in Favour of Three-Person IVF

Back in July, we told you about the UK's progression towards three-person IVF . The procedure in question involves creating a baby using DNA from three people, a man and two women. The buzz surrounding this contentious topic isn't something to be taken lightly, but the technique also isn't a way of paving the road for so-called "designer babies". The procedure would only be available to families with a history of mitochondrial disease. When a person has the condition, the tiny parts of a person's cells don't convert energy properly. This means that the cells in that person's body don't have the energy to function as they should. Mitochondrial disease can be genetic, and be passed down unknowingly from the mother. But if an extra egg, a donor egg, were used in the conception process, such conditions could be prevented, and the child could develop healthy mitochondria. Since mitochondria have their own DNA - that don't affect characteristics such as the child's appearance - some of this will be passed on to the child from the donor. While this is a permanent change to the offspring's DNA that will get passed on for generations, it only actually makes up about 0.1% of the DNA. Three-person IVF, developed at Newcastle University, combines the DNA of the two potential parents with the donor woman's healthy mitochondria in a modified version of regular IVF. But for the process to be given the go-ahead, a vote has to go through Parliament. And this week, that's just what happened. When three-person IVF was put to the vote in the House of Commons, MPs voted 382 to 128 in favour. Now the only step, before the technique can be put into practice, is for it to be approved in the House of Lords. And if everything goes ahead smoothly, the first baby as a result of three people's DNA could be born as soon as next year. The vote is a historic move that could see the UK becoming the first country in the world to introduce laws allowing the conception of children from three people. In the Commons debate, Public Health Minister Jane Ellison said that Parliament was taking a bold step with their vote, but it is something that they had all thought long and hard about. "This is world-leading science within a highly respected regulatory regime," she said. "And for many families affected, this is the light at the end of a very dark tunnel." There are, of course, people against the vote and campaigning against it, claiming it to be unsafe or immoral. But as former Health Secretary Frank Dobson pointed out, critics are all part of the "nature of medicine and science". He said that if absolute certainty had, in fact, been needed then IVF would never have gone ahead in the very first place. Professor Doug Turnbull, the leader of the team that devised the technique at Newcastle University, said the Commons vote was an important hurdle to overcome in the development of the new IVF technique. "I think the quality of the debate today shows what a robust scientific, ethical and legislative procedure we have in the UK for IVF treatments," he said. "This is important and something the UK should rightly be proud of."

Reading the Vesuvius Scrolls

Imagine, within your grasp, a scroll from the first-century AD, holding the secrets of the long-gone past. Unfortunately, this rolled-scroll was buried by Mount Vesuvius, the same volcano that obliterated Pompeii, and is nothing but a charred and burnt relic that could crumble if the wind blew the wrong way. The scroll is not the only one of its kind, either. It belongs to a remarkable library in Herculaneum, containing around 1,800 parchments. Like Pompeii, Herculaneum was buried by ash when Vesuvius erupted in 79AD. It wasn't until the 18th century that Herculaneum's library - the last standing ancient library, for that matter - was excavated. When that happened, various intact contents were brought to light for the first time in many many centuries. Of course, in the two hundred years since then, scientists have been trying to read the scrolls without damaging them. For example, several strategies involved delicately unrolling the scrolls and writing down what they could before the ink disappeared in the modern air, no longer preserved. Some of these fragments were even read successfully, mostly during more recent years, thanks to the help of infra-red camera technology. Most of the scrolls that have been unwound so far have been philosophical prose and poetry that had been lost to modern schools until now. But the method of unwinding the scrolls, even carefully, was damaging much of the ancient works, and it was decided that an alternative technique needed to be put in place. Since then, scientists have also tried looking inside the scrolls using CT scans. This technique was able to reveal the shape and layers of papyri, but, sadly, couldn't decipher the words inked upon them. Some other people tried to look inside the scrolls with CT scans, revealing the shape of the ancient, coiled layers, but they weren't about to decipher the contents. But the amazing thing about people is their curiosity, their thirst for knowledge - especially when it comes to history. And it is thanks to this inquisitiveness (and 3D X-ray imaging technology), that physicists were able to distinguish ink from paper, even deep inside the scroll. Using this kind of technology means that the scrolls don't have to be unfurled and, therefore, won't be damaged. The team is being led by physicist Dr Vito Mocella from Naples' CNR-IMM (Council for National Research for Microelectronics and Microsystems) and their work is published in Nature Communications . Dr Mocella came up with the idea of X-ray phase-content tomography being adapted for use on ancient scrolls when he was on a visit to France. "I was in Grenoble for a collaboration, and they explained to me some new developments using phase-contrast for science, for paleontology," he said. "They sounded like exotic applications, and I said, 'I have another idea.'" A regular X-ray machine works by measuring how much X-ray light shines through different parts of tissue in the body. But when X-rays pass through an object, they become slightly slowed or distorted, and it is this that the new X-ray takes advantage of. The distortion can occur because of the tiniest variations, and measuring the differences - "phase contrast" - can actually produce a very detailed, 3D picture of inside the scroll. The tiny bumps on the papyrus from a long-ago pen and ink were the key to revealing what the scrolls had to say. The team found that the carbon-based ink wasn't very chemically different to the carbonised paper it was used on. But because the papyrus didn't actually absorb the ink, the liquid sort of sat on the surface. When it came to deciphering what they found, a lot of time and guesswork had to be used. You have to remember, the scroll wasn't just rolled but also slightly crushed from surviving being blasted by 300°C (572°F) heat and the chaos ensuing Vesuvius' eruption. On top of this, the fibres of the papyri were in grid form, disguising many of the straighter strokes of the letters. This meant that curved letters were easier to pick out. "I don't think the technique is perfect," Dr Mocella pointed out, adding that he and his team are already working on ways to improve upon the method. The project is one that Dr Mocella and his team are very passionate for - it is not about the ability to read the individual scrolls, but what these parchments symbolise. "Regardless of the individual text, the library is a unique cultural treasure," Dr Mocella explained. "It is the only ancient library to survive almost entire, together with its books. "It is the library itself that confers the status of exceptionality."

India’s Tigers are Making a Comeback!

Our whole lives it seems we are told about the ever-decreasing numbers of endangered animals and how they will probably become extinct in our lifetime. But (as always) we have good news! Official figures from last week indicate that the population of tigers in India has boosted by almost a third in just three years. India is home to around 70% of all the wild tigers in the world, most of which live in one of the country's 50 wildlife reserves that have been created for the tigers since the 1970s. Environment Minister Prakash Javadekar said that the latest figures were proof that the current strategies to give the tiger population a boost were working. Mr Javadekar is putting the success down to creating wildlife reserves for the tigers, which are monitored by specialist government staff. "This is why we want to create more tiger reserves," he explained. "This [tiger boost] is proof of India's biodiversity and how we care for mitigating climate change. This is India's step in the right direction, which the world will applaud." The rise in numbers over the past three years - from 1,706 (2011) to 2,226 (2014) - with further encourage campaigners to carry on fighting to protect the endangered species. The problems lie in the fact that, even though there are reserves for the tigers, their habitat is still threatened by uncontrolled development and poaching. According to Belinda Wright from the WPSI (Wildlife Protection Society of India), a better focus on tiger conservation over the last few years could be responsible for this little surge in numbers. This focus has led to, among other things, better patrolling and monitoring of the reserves. "There still remains the habitat destruction and encroachment," she pointed out. "Hopefully, the new figures will increase the pressure on the government to tread carefully when it is a matter of development in tiger habitats." Outside of reserves, tiger habitats are dwindling terribly, to almost the point of non-existence. The creatures thrive in areas with evergreen, thorn, or deciduous forest, grass jungles or mangrove swamps. But even inside the zone designated for the big cats, food and space can become sparse tourism and other industries are left unchecked. Lots of tigers end up foraging in human-populated areas, which can lead to fatalities on both sides. "We must ensure that animal-human conflict does not happen," concludes Mr Javadekar. "We have proactively decided that we will create more grasslands and water storage in forest areas so that the animals can live well."

New Heart Attack Test for Women

According to experts, if both a man and women visited the emergency room complaining of chest pains, the male would be twice as likely to be diagnosed with a heart attack than the female. But this isn't because twice as many men suffer from heart attacks than women. All of the tell-tale signs of cardiac arrest that you hear about - they don't necessarily apply to everyone. So someone could be admitted with just chest pains and they could still be having a heart attack without any of the other well-known symptoms. Obviously a medical emergency, early diagnosis and treatment of a heart attack could mean the difference between life and death. But the team has found out that heart attacks may be harder to detect in women. This could be down to women having seemingly milder attacks that don't get picked up by the usual tests or ECGs, or simply that the symptoms differ. At the moment, the NHS uses standard troponin tests to check for a heart attack. Troponin is a protein that signals that they might have been damage to the heart muscle, and thus the patient has experience a heart attack. Doctors rely on troponin blood tests to help them judge whether or not a patient with chest pain is going through a heart attack. However, if the results of these tests come back as normal, then a heart-attack diagnosis could be passed over. Scottish researchers from the Royal Infirmary of Edinburgh wanted to see if a more sensitive troponin test would make any difference against these worrying results. They set up clinical trials at the hospital, examining more than 1120 people - both men and women - who had been admitted with chest pains, and published their findings in the BMJ . The study, funded by the British Heart Foundation, used to standard test to check out the troponin levels of all of the patients. The team found that 117 of the male patients (19%) were having a heart attack, compared to only 55 of the female patients (11%). Researchers then used the new, high-sensitivity troponin test to see if and how those number varied. Using the new test, the team found that the number of women diagnosed with a heart attack actually doubled, making it 111 women having heart attacks - 22%, not 11%. In addition, the more sensitive test managed to spot a couple of extra cases in the male patients. While this doesn't sound like a lot, it does mean that these people could be treated for the heart attack they were having, without having their condition otherwise overlooked. Analysing the results, the team realised that the additional cases picked up by the new test differed slightly than those using the standard test. These patients were actually at a higher risk of having another heart attack within a year - or even dying. Dr Anoop Shah is one of the study authors. He explained that the findings suggest the troponin-testing threshold is too high when testing women, and that these levels should be adjusted depending on the gender of the patient. "For some reason, women are less likely to have obvious symptoms," Dr Shah said. He went on to explain that if half of the women having heart attacks are sent home with a negative diagnosis, they could end up having another cardiac event soon after simply because their condition isn't treated. Two versions of the test - troponin I and troponin T - have already been approved by the relevant regulatory bodies, though not all hospitals in the UK have moved on to the high-sensitivity test just yet. The team said that more research, of which the trials have already begun, is required to verify that lowering the troponin threshold for women will actually save lives. This is what the British Heart Foundation believes, according to its Medical Director, Professor Peter Weissberg. "Using a high-sensitivity troponin test could save many more women's lives by identifying them earlier to take steps to prevent them dying or having another, bigger heart attack," he said. If you experience unusual chest pains, call an ambulance or get yourself to your local A&E. And it might be worth your while to ask whoever treats you if they have a high-sensitivity troponin test - it might just save your life.
