Forest fires: the good and the bad

Every year it seems like there’s another disastrous wildfire in the American West. In 2018, nearly 9 million acres were burned in the US alone. Uncontrolled fires often started accidentally by people, rampage and decimate forests. F

or most people, a forest fire is synonymous with disaster. But there are some kinds of forest fires that actually benefit the environment.

A controlled burn is a wildfire that people set intentionally for a specific purpose. Well-thought-out and wellmanaged controlled burns can be incredibly beneficial for forest management—in part because they can help stop an out-of-control wildfire. The technique is called backburning, and it involves setting a controlled fire in the path of the approaching wildfire. All the flammable material is burnt up and extinguished. When the wildfire approaches, there’s no more fuel left for it to keep going, and it dies out.

Controlled burns are also used to prevent forest fires. Even before human involvement, natural, low-intensity wildfires occurred every few years to burn up fuel, plant debris, and dead trees, making way for young, healthy trees and vegetation to thrive. That new growth in turn supports forest wildlife. Forest managers are now replicating this natural strategy when appropriate, starting manageable, slow-burning fires to make room for new life that will help keep the forest healthy in the long term.

The same method is one of WWF’s strategies for maintaining grassland habitats in the Northern Great Plains. Working with partners such as the U.S. Fish and Wildlife Service, WWF has intentionally burned hundreds of acres of prairie land to revitalize these key habitats. The fire burns off tall, aggressive vegetation that isn’t as hospitable to wildlife, and makes room for new growth that attracts bison, birds, and prairie dogs.

This doesn’t mean all intentional wildfires are good – far from it. Many of the fires intentionally set for agriculture and land clearing are at best ill-advised, and at worst devastating. Slash and burn fires are set every day to destroy large sections of forests. Of course, these forests don’t just remove trees; they kill and displace wildlife, alter water cycles and soil fertility, and endanger the lives and livelihoods of local communities. They also can rage out of control. In 1997, fires set intentionally to clear forests in Indonesia escalated into one of the largest wildfires in recorded history. Hundreds of people died; millions of acres burned; already at-risk species like orangutans perished by the hundreds; and a smoke and ash haze hung over southeast Asia for months, reducing visibility and causing acute health conditions.

That’s exactly why WWF helps governments around the world crack down on slash and burn deforestation. WWF also works with farmers and companies to stop unnecessary agricultural burns. And when our scientists think fire could be the best solution for revitalizing wild areas, we bring the right experts to the table to study the situation and come up with a plan.

All fire is risky. To minimize that risk as much as possible, controlled burns must be well-considered, wellplanned, and ignited and maintained by trained professionals. The bottom line? Fire can be a tool for conservation, but only when used the right way.

Digitizing Healthcare: How Technology Is Improving Medical Care 

                                                                                                                    by Tricia Hussung

A wide variety of digital innovations are revolutionizing healthcare — and technology in medicine is here to stay. How are these changes impacting the delivery of care, and what skills are needed to succeed in this bold new world? It’s no secret that, as a society, technology has become a part of our everyday lives. In fact, almost 60 percent of American adults own a smartphone, and 42 percent of that same population (American adults) owns a tablet computer. Though technology has been permeating almost every aspect of our lives, until recent years the medical field has been largely unaffected by the rapid pace of technological innovation that is characteristic of the Digital Age. However, this is changing.

This ubiquity of technology is beginning to extend into the medical field. Advances in medical technology are changing medicine by giving physicians more information — as well as better, more specific data. 

New Medical Technology: Innovations

So just what are these new advances in technology? The following are just a few of the many innovations that have occurred in medical technology over the past year alone. Some of these leading technologies are still being developed, while others are slowly being introduced into mainstream medical practice.

• The modern hospital experience: Several medical technology companies are looking to update hospital stays to keep pace with the needs of modern patients. To more easily integrate changing technology, these new rooms would feature interchangeable parts that are easily adapted to the specific situation of a patient. The seamless design would have a minimal impact on facility operations while increasing patient comfort and connectivity.
• Surgery simulation: The Roswell Park Cancer Institute has partnered with the University of Buffalo’s School of Engineering and Applied Sciences to create the Robotic Surgery Simulator (RoSS). This innovation allows real-world views of surgeries while eliminating the need for a live environment to train aspiring surgeons. It gives these medical professionals the space to experiment in a simulated environment, rather than risking making mistakes on real patients.
• Cloud-based data and software: Applications like referralMD help healthcare providers create referrals digitally and reach millions of patients and providers who are in search of treatment options. The current, paper method of referrals causes almost 50 percent of patient referrals to never actually result in doctor’s visits. This present gap in care “causes patients to lose treatment (and) the healthcare facility to lose money.” Software innovations like these are part of the relatively new field of health informatics, which aims to collect, store, analyze and present health data in a digital format. 

With widespread innovations like these affecting patient care practices, it is not surprising that the way medical records and information are stored and shared is changing as well. These technological advancements are costeffective and improve the ability of medical professionals to diagnose and treat health issues of all kinds. Two of the main changes that are revolutionizing the future of healthcare are electronic medical records and health information exchange. Future won´t be the same for medical field. Are you ready for what is coming?

Predictions for the future of 'smart' education

Posted by Charley Rogers - January 22, 2018

    A wave of new technology has been introduced into schools up and down the country changing the way teachers deliver lessons and how students learn.

    A research by Randstad Education found schools and colleges have adopted the latest tech to improve teaching and make lessons more interactive and engaging. Some of the innovations already in use include ‘gamifying’ lessons by incorporating game-like rules and tasks to increase motivation. For example, Shireland Academy in the West Midlands included Minecraft on its curriculum.

    Education, the research found, will become more project-based and include more interactive content to keep up with students’ changing attitudes towards traditional media. Classrooms, it is predicted, will join the Internet of Things – a network of devices like smartwatches that connect and share data with other items and systems – and create ‘smart schools’ where the teachers, students and devices become more connected.

    Pressure on teachers – 75% find their workload unmanageable – as well as rising student numbers means technology will play a larger role performing tasks to save time. Teachers are also reaping the rewards as lessons and assessments move out of the classroom and onto platforms that make it easier for them to chart progress and achieve a better work-life balance. Education experts have highlighted the importance of new techniques that help teachers do their jobs.

    However, while tech will become more commonplace in the classroom, it is expected to compliment teachers and not replace them. It´s important to understand that teaching tools have come a long way since the days when teachers used to write on chalkboards and present using an overhead projector.

    The research says that students today benefit from some of the most exciting technology available to schools, but it’s not just the pupils who benefit from these innovations through invigorating lessons and virtual learning. Teachers are also reaping the rewards as lessons and assessments move out of the classroom and onto platforms that make it easier for them to chart progress and achieve a better work-life balance.

    Technology has arrived and the teachers and classrooms of tomorrow are here today.

                                  Why so few nurses are men

      Ask health professionals in any country what the biggest problem in their health-care system is and one of the most common answers is the shortage of nurses. In ageing rich countries, demand for nursing care is becoming increasingly insatiable. Britain’s National Health Service, for example, has 40,000-odd nurse vacancies. Poor countries struggle with the emigration of nurses for greener pastures. One obvious solution seems neglected: recruit more men. Typically, just 5-10% of nurses registered in a given country are men. Why so few?

      Views of nursing as a “woman’s job” have deep roots. Florence Nightingale, who established the principles of modern nursing in the 1860s, insisted that men’s “hard and horny” hands were “not fitted to touch, bathe and dress wounded limbs”. In Britain the Royal College of Nursing, the profession’s union, did not even admit men as members until 1960. Some nursing schools in America started admitting men only in 1982, after a Supreme Court ruling forced them to. Senior nurse titles such as “sister” (a ward manager) and “matron” (which in some countries is used for men as well) do not help matters. Unsurprisingly, some older people do not even know that men can be nurses too. Male nurses often encounter patients who assume they are doctors.

      Another problem is that beliefs about what a nursing job entails are often outdated – in ways that may be particularly off-putting for men. In films, nurses are commonly portrayed as the helpers of heroic male doctors. In fact, nurses do most of their work independently and are the first responders to patients in crisis. To dispel myths, nurse-recruitment campaigns display nursing as a professional job with career progression, specialisms like anaesthetics, cardiology or emergency care, and use for skills related to technology, innovation and leadership. However, attracting men without playing to gender stereotypes can be tricky. “Are you man enough to be a nurse?”, the slogan of an American campaign, was involved in controversy.

      Nursing is not a career many boys aspire to, or are encouraged to consider. Only two-fifths of British parents say they would be proud if their son became a nurse. Because of all this, men who go into nursing are usually already closely familiar with the job. Some are following in the career footsteps of their mothers. Others decide that the job would suit them after they see a male nurse care for a relative or they themselves get care from a male nurse when hospitalised. Although many gender stereotypes about jobs and caring have crumbled, nursing has, so far, remained unaffected.

                          Can you learn in your sleep?

      Sleep is known to be crucial for learning and memory formation. What's more, scientists have even managed to pick out specific memories and consolidate them during sleep. However, the exact mechanisms behind this were unknown — until now.

      Those among us who grew up with the popular cartoon "Dexter's Laboratory" might remember the famous episode wherein Dexter's trying to learn French overnight. He creates a device that helps him to learn in his sleep by playing French phrases to him. Of course, since the show is a comedy, Dexter's record gets stuck on the phrase "Omelette du fromage" and the next day he's incapable of saying anything else. This is, of course, a problem that puts him through a series of hilarious situations.

      The idea that we can learn in our sleep has captivated the minds of artists and scientists alike; the possibility that one day we could all drastically improve our productivity by learning in our sleep is very appealing. But could such a scenario ever become a reality?

      New research seems to suggest so, and scientists in general are moving closer to understanding precisely what goes on in the brain when we sleep and how the restful state affects learning and memory formation.

      For instance, previous studies have shown that non-rapid eye movement (non-REM) sleep — or dreamless sleep — is crucial for consolidating memories. It has also been shown that sleep spindles, or sudden spikes in oscillatory brain activity that can be seen on an electroencephalogram (EEG) during the second stage of non-REM sleep, are key for this memory consolidation. Scientists were also able to specifically target certain memories and reactivate, or strengthen, them by using auditory cues.

      However, the mechanism behind such achievements remained mysterious until now. Researchers were also unaware if such mechanisms would help with memorizing new information.

      Therefore, a team of researchers set out to investigate. Scott Cairney, from the University of York in the United Kingdom, co-led the research with Bernhard Staresina, who works at the University of Birmingham, also in the U.K. Their findings were published in the journal Current Biology.

      Cairney explains the motivation for the research, saying, "We are quite certain that memories are reactivated in the brain during sleep, but we don't know the neural processes that underpin this phenomenon." "Sleep spindles," he continues, "have been linked to the benefits of sleep for memory in previous research, so we wanted to investigate whether these brain waves mediate reactivation. If they support memory reactivation, we further reasoned that it could be possible to decipher memory signals at the time that these spindles took place."

      To test their hypotheses, Cairney and his colleagues asked 46 participants "to learn associations between words and pictures of objects or scenes before a nap." Afterward, some of the participants took a 90-minute nap, whereas others stayed awake. To those who napped, "Half of the words were [...] replayed during the nap to trigger the reactivation of the newly learned picture memories," explains Cairney.

      "When the participants woke after a good period of sleep," he says, "we presented them again with the words and asked them to recall the object and scene pictures. We found that their memory was better for the pictures that were connected to the words that were presented in sleep, compared to those words that weren't," Cairney reports.

      Using an EEG machine, the researchers were also able to see that playing the associated words to reactivate memories triggered sleep spindles in the participants' brains. More specifically, the EEG sleep spindle patterns "told" the researchers whether the participants were processing memories related to objects or memories related to scenes.

      "Our data suggest that spindles facilitate processing of relevant memory features during sleep and that this process boosts memory consolidation," says Staresina. "While it has been shown previously," he continues, "that targeted memory reactivation can boost memory consolidation during sleep, we now show that sleep spindles might represent the key underlying mechanism."

      Cairney adds, "When you are awake you learn new things, but when you are asleep you refine them, making it easier to retrieve them and apply them correctly when you need them the most. This is important for how we learn but also for how we might help retain healthy brain functions."

      Staresina suggests that this newly gained knowledge could lead to effective strategies for boosting memory while sleeping.

      So, though learning things from scratch à la "Dexter's Lab" may take a while to become a reality, we can safely say that our brains continue to learn while we sleep, and that researchers just got a lot closer to understanding why this happens.

The true potential of technology to change behavior

    Technology could successfully change behaviours where decades of campaigns and legislation have failed. With the quantified self already walking among us and the internet of things within easy reach, digital technology is creating unprecedented opportunities to encourage, enable and empower more sustainable behaviours.

     If we are to unlock the power of technology we must be more ambitious than simply digitising analogue strategies or creating another communications channel.

    The true potential of technology lies in its ability to do things that nothing else can do. In behaviour change terms, the potential to succeed where decades of education programmes, awareness campaigns and product innovation have failed; to make a difference where government policy and legislation has had limited impact.

    Using behavioural insights, it is possible to highlight the bottlenecks, drop out points and achilles heels of traditional behaviour change efforts — the reasons why we have failed in the past — and apply the unique possibilities of technology to these specific challenges.

    Overcoming our limitations

    Luckily, the history of the human race is almost defined by its ability to invent stuff that bolsters its feeble capabilities. That stuff is, of course, what we generically refer to as 'technology'. And in the same way that the internal combustion engine and the light bulb allow us to overcome our relatively feeble powers of motion and perception, so digital technology can be directed to overcoming our relatively feeble powers of reasoning, selfcontrol, motivation, self-awareness and agency—the factors that make behaviour change so difficult.

    Herein lies the true potential of technology: not in the laboratory or the workshop, but in an understanding of the behavioural dynamics that define the human condition, both generally and within the context of a specific user-group, market segment or community.
