Aspirin is often considered a wonder drug due to its versatile use in treating inflammation, reducing pain, and helping to prevent heart-related disease. However, there is more to it. Aspirin is actually cancer-preventive. Studies have shown that a daily low dose of aspirin, medically prescribed for more than five years, lowers the risk of cancer-related deaths by at least 30%. So, should we all start taking aspirin on a daily basis to lower our chances of getting cancer?
No, not exactly. This is because many aspects of aspirin’s cancer-preventive effects are still poorly understood. Particularly, researchers have not yet pinpointed what enables aspirin to selectively kill early-stage cancer cells and not healthy cells. This is the scope of the research currently being carried out at the Yeast Molecular Biology and Biotechnology Laboratory (headed by Prof. Rena Balzan).
Maria Azzopardi
The secret behind aspirin’s tendency to kill certain cells but not others seems to lie in the physiology of the exposed cells. Aspirin exploits the natural differences between healthy and cancerous cells to eliminate malignant cells before they can take over.
Oxygen, if transformed into ‘Reactive Oxygen Species’, is known to cause DNA mutations that can lead to cancer. Through this research, we studied mutated yeast cells which are a relevant model of early-stage cancer cells due to their low tolerance to oxygen-associated stress. We then identified genes in these mutant yeasts which are affected by aspirin.
One of aspirin’s targets is a key metabolite required for the production of energy-rich compounds vital for cell survival. We found that aspirin creates a shortage of this metabolite in mutated yeast cells, causing them to run out of energy and die.
This implies that early-stage human cancer cells may suffer a similar fate and, more importantly, partly explains how aspirin prevents tumour formation. Such knowledge may prove useful in the development of novel anti-cancer treatments.
This research was carried out as part of Project “R&I-2015-001”, financed by the Malta Council for Science & Technology through the R&I Technology Development Programme. This research is being carried out as part of Azzopardi’s Ph.D. project at the Centre for Molecular Medicine & Biobanking and the Department of Physiology & Biochemistry, University of Malta
EcoMarine Malta’s boat tours are leading the way in environmentally sustainable tourism around the Maltese Islands. Founder Patrizia Patti talks to Edward Thomas about how economic success doesn’t need to be sacrificed in order to protect nature.
Aquarter of Malta’s GDP comes from the tourism industry. It accounts for €2 billion annually and shows no sign of slowing down. Tourist expenditure went up by 13.9% from 2016 to 2017 alone. It constitutes one in every seven jobs in the local economy and maintains a close link to development: better hotels, improved roads, more diverse shops and restaurants. Beyond the economic benefits, tourism promotes and celebrates local customs, food, traditions, and festivals, creating a sense of civic pride.
However, there are concerns. In July and August, Malta, Gozo, and Comino are covered by thousands of holiday-makers flocking in. This is a not only a burden on already strained island resources and infrastructure including water, waste management, and traffic congestion, but it pushes many coastal habitats and aquatic ecosystems to the breaking point, with drastic impacts on local biodiversity.
Patrizia Patti, founder of EcoMarine Malta
Marine biologist Patrizia Patti laments how ‘people go with speed boats to Comino carrying beers, drinking, throwing bottles into the sea, playing loud music… it disturbs everything.’ If larger tour companies made a small effort to be more responsible, it could have a large effect, she says. ‘Even a simple announcement on a microphone, reminding people they are in a protected area and to behave in a certain way, advising people to respect nature, would help. It’s only a small reminder but it would help a lot.’ Always looking to lead by example, and to show that small actions can have a great impact, Patti set up EcoMarine Malta. The start up organises responsible boat tours around the island, where the international code of conduct is followed and people can experience the joy of encountering dolphins, turtles, and seabirds in their natural habitat.
FACE TO FACE
Patti says their goal is to establish profound personal connections between people and the sea in the hopes that it will change behaviour. She has been passionate about marine biology since the age of 17, when she first encountered a dolphin. That happened during a school trip to an aquarium. She says ‘it was exciting because it was the first time I saw a dolphin, but it was terrible seeing it trapped in a small tank. It made me so sad.’ The emotional response was strong enough to move Patti to tears. ‘It was at that point I decided I wanted to become a marine biologist. I wanted to help.’
Patti went on to study the ecology of sperm whales in the Ligurian Sea before travelling far and wide, gaining experience working with marine mammals in Canada, the Maldives, and the Red Sea. In 2013, she cofounded Costa Balenae Whale and Nature Watching in Italy, a company, like Eco Marine Malta, which strongly focuses on bringing humans closer to marine wildlife, forming lasting memories that inspire them to consider their environmental impact and educating both children and adults about the natural biodiversity of the Mediterranean Sea.
How can you love something and want to protect it when you’ve never seen it?
Seeing these animals and experiencing their natural environment first hand is vital to establishing an emotional bond. This is what then engages people and inspires them to change their behaviour. ‘How can you love something and want to protect it when you’ve never seen it?’ Patti questions. By opening local and tourists’ eyes to the majesty of indigenous species, EcoMarine Malta create compassion and motivate people to take responsibility for the environment too. They also chip away at the sense of helplessness many feel when it comes to ‘actually making a difference.’ EcoMarine Malta provide education and information for their passengers to follow. Patti, who leads the tours herself, goes into how they can enjoy Malta’s beaches responsibly and sustainably, empowering them to take ownership for their actions and decisions before it’s too late.
MONEY PROBLEMS
Filming the dolphins swimming by the side of the boat
It’s not always been plain sailing for EcoMarine Malta and their boat trips. Patti firmly believes that environmental conservation can be a tool to increase economic growth and employment in Malta. ‘Even if we act like an NGO, we decided to be a private company
because we want to create job places and grow and be able to provide the best service possible,’ Patti says. But not everyone agrees. Patti has received plenty of push back from others in the field as she lobbies for best practices to be enforced around the islands.
Some views are severely narrow and short-sighted, rooted in the belief that any sort of restriction of operations is bad, even if inspired by respect and protection for the natural resources they use. ‘People have to understand that a protected area is to enjoy for a long time. Maybe not now, maybe for one or two years you have to be careful, you can’t do everything you want to do. But after those two years, you can enjoy a new beautiful area, rich in life,’ explains Patti. Setting up EcoMarine Malta as a for-profit enterprise to prove these people wrong, however, has led to another kettle of fish. Because they’re not an NGO, applying for sponsorship and funding is a major challenge. Potential benefactors often dismiss collaboration, telling Patti that the company should be able to support its own endeavours.
This lack of support saw EcoMarine Malta having to rent boats from various charter companies, a massive expense. Externally renting a boat brought with it uncertainty and inflexibility. Last-minute dropouts or weather changes forced them to cancel tours and lose a lot of money. ‘The boat rental still had to paid for,’ she says. But things are looking up. EcoMarine Malta purchased their own boat this summer, and Patti is working hard on getting all the permits in place to have it out on the water as soon as possible. ‘Now we will be able to plan our own routes and diversify the tours we offer. At the moment, we have six tours available to choose from, including a sunset tour when marine life is at its most active,’ she smiles.
GET THEM YOUNG
2018 might be EcoMarine Malta’s first full summer season, but that doesn’t stop Patti from dreaming big about their future. She and her team want to do more outreach and education and are working on offering a series of courses for students aged between 10 and 16 years old. These children will be able to participate in a day of hands-on classroom activities, discovering and learning about sustainability and the ecosystem of the Mediterranean, followed by a boat trip to implement their new knowledge, observing and identifying the variety of wildlife and nature surrounding them and their island. ‘We hope to inspire a whole new generation of marine biologists and environmental scientists,’ Patti says.
With an army of environmentalists in the making, Patti hopes they will take over her role in the future. That would allow her to refocus on a passion she is itching to pick up again: searching for evidence of sperm whales in the Mediterranean surrounding the Maltese Islands. Her eyes light up as she admits to me, ‘I love outreach, but my personal dream is to spot sperm whales in Malta.’ Researchers know that juvenile and female sperm whales in the Atlantic remain in warm waters while the males migrate to the poles to feed, but movements and social dynamics of pods in the Mediterranean are still unclear.
With an army of environmentalists in the making, Patti hopes they will take over her role in the future.
Looking forward, Patti is working hard to establish networks with other entities and NGOs who share the same vision. EcoMarine Malta already collaborates with the likes of Birdlife Malta and has been involved with beach ‘Clean Up’ projects in the past year. Patti asserts that despite everything, ‘the Maltese public and tourists are some of the most enthusiastic and passionate people we’ve worked with so far. It’s great to see people of all ages and backgrounds, coming together to work on a common goal.’
‘Everyone can contribute different things, and together, it adds up to make a big difference.’ Patti is keen to encourage people to help in whatever way they can. To cooperate with others and not feel overwhelmed or alone in their efforts. ‘It’s not possible to do it alone. We need to work together, holistically, caring about the land, sea, and air, to protect the island’s environment.

At face value, renewable energy seems the smartest choice for a cleaner tomorrow. But when green energy cannot be stored, what do we do during scorching summer afternoons and cold winter nights? Cassi Camilleri speaks to Prof. Joseph Cilia and his team to find out more about the innovative solution they are developing.
The movement towards sustainability has been ramping up over decades. Now, it feels like it has reached fever pitch. Headlines are hogged by the latest scary statistic on air, land, or sea pollution. People are rallying, demanding that new measures be implemented to reduce waste and clean up our streets. Despite this call, real advances on these issues always manage to find themselves obstructed by seemingly ‘rational’ arguments.
For one, renewable energy isn’t as reliable and cheap as fossil fuels. Overhauling the status quo is expensive and requires significant effort, both of which make people frown. Solar power depends on the sun, wind power depends on wind, both of which are quite unpredictable. But while this is true, it shouldn’t even be considered an issue. We live in a country on the receiving end of 550,000 GWh of solar energy annually, while we need only 3,484 GWh to cover all energy consumption. Let that sink in.
Of course, I hear your concerns about the quantity of solar panels needed to harvest that energy—Malta is so small and built up. But in reality, only 28% of our island is built up, and just 7% of the remaining land would be required to meet the total energy demand. So yes. There are solutions to our energy woes. And those solutions need to be combined to create the best results.
Thanks to support from Abertax Kemtronics and MCST (Malta Council for Science and Technology), Prof. Joseph Cilia and his team of researchers (Department of Industrial Electrical Power Conversion, University of Malta [UM]) have found that houses with a normal-sized photovoltaic system can supply more than 100% of the total energy they need during summer. During winter, that figure falls to 50%. To manage this drop, energy can be supplied through other sources. Enter the Micro-CHP.
A small combined heat and power (CHP) machine provides seasonal energy in two forms: electrical and thermal. It consists of a standard internal combustion engine coupled with a generator that produces electrical energy. The thermal energy resulting from the engine and exhaust is then recovered using water heat exchangers and reused to heat the house and domestic water.
While similar systems already exist, most are geared towards industrial applications. The rest cost, on average, around €15,000—pricing a large cross-section of society out. The system Cilia and his team have developed makes use of a grid PV system, combined with battery energy storage, a heating and cooling heat pump load, a CHP machine, and LED lighting. It is also an easy-to-install, plug-and-play solution that fits into your current setup, as opposed to a complex installation that would force everything to change with it. By the end of it, the team’s CHP will cost the consumer around €8,000.
Their study of Maltese households showed that in a typical medium-sized household, energy needs vary substantially. The energy fluctuations for a typical Maltese household are usually about 500 kWhr between the summer and winter seasons. In this case, storing this energy in a battery is not feasible. What is feasible is simply making more efficient use of the LPG gas tank that most people already have and use at home. If one wants to be renewable, one can also use ethanol or methanol to operate the CHP, which, if used in combination with a heat pump, can easily reach an efficiency of 150% to 180% in heating mode.
Added to this, the team’s system is unique compared to others on the market. It is connected directly to the main electricity supply, tapping into it whenever the system needs support, while not using mains electricity when enough energy is being produced by the system itself.
The system is scalable due to the plug-and-play concept the system is based on. It can be upgraded as more and more savings are made on electricity bills. ‘The idea is to provide a cost-effective solution that even low-income households can afford,’ says Cilia. This can not only trigger a widespread use of energy generation and storage for domestic use, but also turn consumers into suppliers of their own energy needs. Gone are the days of being dependent on the grid.

In the challenge of keeping our seas clean, plastics FAIL. And yet, during the last decade, we produced more of it than in the last 100 years combined. Dr Adam Gauciwrites about his team’s efforts to categorise the microplastics from Malta’s beaches and how those efforts will contribute towards the war on plastic.
Water is our number one resource. It not only sustains life, but also supports the economy and its development. And yet, water is taken for granted. Kirsty Callan talks to Marco Cremona, the man behind the revolutionary water treatment solution that promised to reduce Maltese hotels’ water use by 85%.
STEM subjects tend to intimidate, seeming inaccessible to the untrained eye. Dr Vanessa Camilleri, Dr Marie Briguglio, and Prof. Cristiana Sebu speak to Becky Catrin Jones about how they are challenging preconceptions by combining science and art at Science in the City, Malta’s national science festival.
It’s 2018. We live in a world where saliva samples sent out from the comfort of our own homes return to us with a sprawling outline of our ancestry and where some of the biggest social media influencers are robots. Despite this progress, utter the word ‘scientist’ and the outdated image of men in white lab coats still abound.
When advances in STEM (Science, Technology, Engineering, Mathematics) direct almost every aspect of life, why is it that so many still switch off the minute we mention science?
Researchers haven’t always had the best PR. In films and TV, science is often portrayed as a foreign language, gibberish to most. Real life is not always that much better, with some researchers needing to carry a jargon-busting dictionary around to translate what they study. To improve its reputation, we need a more creative approach that can break these stereotypes and bring science to the masses in a way that doesn’t send people running for the hills.
Science in the City (SitC), Malta’s science and arts festival, is the perfect opportunity for researchers at the University of Malta (UM) to bring their research to citizens in a way that doesn’t need subtitles.
Prof. Cristiana Sebu
Professor Cristiana Sebu (Department of Mathematics, UM) joined UM only three years ago, but has already made a firm mark. With a background in Applied Mathematics, she moved to the university as an Associate Professor, setting up a new course stream for undergraduate students in Biomathematics. Sebu’s interests lie in the practical applications of mathematics, particularly in biology, and in exploring how mathematics underpins essentially everything in life. ‘The links between mathematics and biology are strong,’ Sebu asserts. ‘We need to be able to make predictions and apply mathematical modelling to understand complex and intertwined biological systems such as signalling pathways in the body or ecosystems in the environment.’
That said, Sebu is still very aware that her love for mathematics is not often shared by the wider world. The word ‘mathematics’, however applied it might be, still strikes fear into the hearts of many. In an effort to counter this reaction and replace it with a more positive one, Sebu is joining the myriad of researchers at SitC and adding music to the mix.
‘Maths provides the building blocks and the structure of music,’ says Sebu. ‘Debussy, Mozart, Beethoven, and so many more used a mathematical pattern known as the Fibonacci Series in their scores.’ The Fibonacci sequence is an infinite pattern of numbers where the next number is the sum of the two previous ones, going from 1, to 1, 2, 3, 5, 8, where (1+1) = 2, (1+2) = 3, and so on. This sequence is closely related to what’s known as the Golden Ratio, an infinite number which can be found in so many examples throughout nature, from the composition of bee colonies to the shape of seashells and the patterns in sunflower seeds.
Debussy, Mozart, Beethoven, and so many more used a mathematical pattern known as the Fibonacci Series in their scores.
To highlight this elegance, Sebu has teamed up with jazz composer Diccon Cooper. The performance, entitled ‘Jazzing the Golden Ratio’, will feature presentations of the Golden Ratio in art, the environment, and the human body, accompanied by Fibonacci-inspired jazz music specially commissioned for the festival. Sebu herself will also be there, sharing her thoughts about the significance of this pattern in the world around us. ‘People see arts and science at odds, but the two are very much embedded in each other,’ Sebu states. ‘Hopefully we’ll be able to demonstrate the beauty of mathematics at Science in the City this year.’
Dr Vanessa Camilleri
The significance of this connection between arts and science is a notion shared by Dr Vanessa Camilleri (Faculty of ICT, UM). After working on a project combining Artificial Intelligence (AI) with behavioural studies at Coventry University, Camilleri found a niche research environment using immersive technology and design to influence our decisions and behaviours. Returning to the UM, she worked on a Virtual Reality (VR) headset allowing teachers to experience what it might be like for a child with autism in a classroom.
‘Unless you experience something, it’s very difficult to reach a deep level of empathy,’ Camilleri said of the idea behind the project. ‘We wanted to give [teachers] the opportunity to build new memories through VR, and help them understand the needs of the child in greater detail.’
For SitC this year, Camilleri is taking a different approach. The VR headsets are having the night off, and attendees will need nothing but their smartphones to see science brought to life in artistic form. Using Alternative Reality (AR) methods, she’s collaborating with artists Matthew Attard and Matthew Galea to bring a fourth Triton to the fountain for one night only through a project funded by Valletta 2018. By downloading the smartphone app, attendees will see the new fountain brought to life through their phones. In the build-up to the festival, the artists are using eye-motion tracking and heat mapping sensors on volunteers to see which bits of the current statue draw their attention. This is then translated into the final depiction, making the fourth Triton as eye-catching as the current three.
Prof. Cristiana Sebu
Lecturer Dr Marie Briguglio (Faculty of Economics, Management & Accountancy, UM) is also hoping to use art to bring her subject to life, albeit in a more sober manner. As a behavioural economist, Briguglio’s focus is on a population’s impact on environment and how we can police this. In particular, at SitC, she wishes to convey the ‘Tragedy of the Commons’—the notion that free or common assets such as public space or air are likely to be exploited by the masses due to sense of entitlement combined with lack of responsibility.
To do this, Briguglio recruited the expertise of Steve Bonello, a cartoonist with a political bent. ‘Working out how best to design environmental regulation underpins much of the research I am involved in. But it’s also very evident in many of the cartoons Steve draws,’ says Briguglio. ‘I soon realized that there was enough material to write a book.’ And so they did, combining the work of faculty with cartoons to produce the comic The Art of Polluting.
Home truths about how we personally damage the world we live in might not make for easy reading, but Briguglio hopes the fusion between arts and science will make this message easier to swallow. ‘It is intended to bring to light research on environmental pressures, status, and responses in a manner that is accessible and also fun.’ The book itself will be displayed as part of a larger instalment titled No Man’s Land, which will include a live action play, more detailed research, and even a free tree-planting stall.
Putting research on the main stage is no new concept to any of these three, and this year’s SitC is certainly not their first venture into science communication. The projects they’ve put forward have all stemmed from previous public engagement ideas. Camilleri worked with the same artists on an AR feature about Greek Mythology, and she regularly translates her research for mass media. A science communication event, Go For Research, which was spearheaded by the Faculty of Science and Directorate of Curriculum Management and aimed at the Junior Science Olympiads was where Sebu’s idea for highlighting the beauty of mathematics was born.
The passion for their subjects is infectious in all three researchers. Each one listed the prospect of inspiring their audience as their top goal for the festival. Shaking up science communication by presenting it in a way we wouldn’t expect, through musical maths, theatrical economics, and artistic AI, provides an opportunity for researchers and citizens alike to see science through a new lens. One where progress seems brighter and kinder.
Sharks are a vital part of marine ecology, keeping everything beneath them in the food chain in check. But they’re being caught and consumed at an alarming rate, and people aren’t even realising it. Randel Kreitsberg writes about Sharklab Malta founder Greg Nowell’s work in raising awareness and preserving these fantastic creatures.
I’ll pick you up at 2.45,’ Greg says casually. ‘AM?’ ‘Yes,’ he smiles.
There is a one hour gap, between three and four in the morning, before the Pixkerija (fish market) in Marsa opens to the public. This is the time when fishermen arrive with their catch, but their clients, chefs and managers of Maltese restaurants, have yet to appear.
It is also when Greg Nowell, founder of the Sharklab Malta elasmobranch conservation group, and a small crowd of volunteers inspect the shelves and boxes of fresh catch. They’re looking for two local catshark species—nursehounds and lesser spotted catsharks—so they can cut them open and save the viable eggs still inside the females in the hopes of releasing them back into the wild.
AN ENGLISHMAN’S LIVING ROOM
Greg Nowell is a diver whose ‘regular’ job involves electronics quality auditing and building renovation works. In 2011, while at a local fish market, Greg noticed something unusual. One of the catsharks on sale had an egg protruding from it. ‘I took it out, and it looked intact. I could see there was something inside,’ he says. He decided to put the egg in an aquarium to see what would happen, and while the shark pup inside developed successfully over the course of a few weeks, it eventually died before the two month mark. Looking back, Nowell can confidently say now that it had everything to do with temperature.
‘Originally, we didn’t know all the parameters we needed to develop the eggs. Temperature was the big eureka moment. Most of the eggs collected during the year’s early months started to develop nicely, but after some time most of them simply stopped – until we installed the cooling system! Now if we have an egg that starts to develop, it has a 95% chance of making back into the sea,’ Nowell says proudly.
It took two years to successfully release the first market-sourced shark pup. Nowell released the baby himself. ‘I don’t know if it was saltwater in my mask or tears—it was beautiful!’ More than 280 shark babies have been released into our seas since then.
MOVING ON
Today, a lot has changed. The Sharklab team and volunteers proactively check all the egglaying shark species in fish markets before they’re sold. The shark pup aquariums have also moved out of Nowell’s living room and into tanks in the Malta National Aquarium, where citizens can learn and foster an appreciation for them.
While the initial plan for our interview was to go to the fish market and save the eggs still alive in the female sharks, a storm put an end to those plans. The fishermen couldn’t go out to sea, so we made our way to the Malta National Aquarium instead.
The aquarium looks different from others I have visited over the years. Yes, there are some tropical species and colourful Japanese Koi Carps, but the majority of species there are local. This includes 20 to 30 cm nursehound pups and their empty egg-cases. It immediately strikes me that the focus of the aquarium is conservation and education, rather than the display of pretty fish.
Sharklab science officer Lydia Koehler praises the national aquarium for their support. She emphasises that with the help of the national aquarium, other countries are following suit and scavenging viable eggs from caught female sharks. Currently, there is a Sharklab in Bosnia Herzegovina, founded with Sharklab Malta, as well as activities in Spain and Greece, which are making strides. ‘In Spain they have a lot of Blackmouth Catsharks,’ Koehler says. ‘They had their first release couple of weeks ago.’
WHAT CAN WE DO?
‘A major part of what Sharklab Malta does is raise awareness and educate people,’ Koehler says. ‘And we have seen a change amongst younger people, appreciating the animals for what they are.’ But there are challenges too. ‘There is a generational gap,’ she notes. ‘Some older people don’t go into the water because there could be sharks in it. They are still very afraid of them.’
At the same time, shark is still a popular menu item with locals and tourists, which is why populations are heavily exploited in Malta. Koehler says that the volume of catches is astounding. ‘The first few times you go to the fish market, you don’t actually realise how many sharks they bring back. That was one thing that really shocked me. Especially for the small spotted catsharks. They come in boxes of 40 to 60 individual sharks. Once we saw them bring in 40 boxes in one day.’
Koehler says that most people don’t even know they are consuming shark. ‘Traditional Maltese fish soup, aljotta, often has several different species of shark in it,’ she says. ‘The issue is people don’t call them sharks—they call it fish soup. If you ask people whether or not they eat shark, their reply is: no, we don’t. But if you ask: do you eat mazzola? The reply is yes. They don’t know sharks are used in it,’ Koehler says, joking then that we should give up mazzola for good.
But there is more to Sharklab than the sharks themselves, Nowell notes. Towards the end of our trip to the aquarium, he highlights the need for better ecosystem management. ‘The animals, as fascinating as they are, live in an environment,’ he says. That itself deserves attention.
‘Plastic is a major issue for all marine life, and if you start affecting any part of it, you’re affecting sharks,’ Nowell says. ‘We also need to be knowledgeable about the species we’re consuming. Overexploitation of fish species because we like to eat them has a direct impact on sharks, because they can get caught accidentally as bycatch.’ Being apex predators, sharks have a critical role in maintaining the species below them in the food chain. They remove the weak and sick individuals, all while keeping competitors balanced to ensure species diversity. Sharks are essential for ocean health, and they have to be protected.
There is much to be done. And there are lots of opportunities to get started, as Nowell and his volunteers have clearly shown by empowering themselves and taking action. But as with every environmental issue, larger numbers make the loudest noise. And so it always boils down to a very simple question: Do we care enough to add our voices to the call?
A scientist and a linguist board a helicopter, and the scientist says to the linguist, ‘What is the cornerstone of civilisation, science or language?’ It might sound like the opening line of a joke, but it’s actually from the opening sequence of the film Arrival (2016). In the film, aliens have landed on our doorstep, and our scientist and linguist have been chosen as suitable emissaries to establish contact. The scientist, perhaps wishing to size up his new colleague, then poses the question. Whose field has been more important to the advancement of the human race? Science or language?
In reality, they are both wrong (or both half-right). It is true that language was necessary for us to organise as a species, forming complex networks of cooperation over vast distances and time. Without specialising our efforts and collaborating, we could not have built our great structures, supported large communities, or migrated over all continents. Yet, without science, without improving our understanding of the natural world, we would still be at its mercy.
Science is the tool we use to change circumstance. When populations are dying from an infectious disease, we create a vaccine. When we’re unable to grow enough food to support ourselves, we develop a better strain of crop. When we struggle to transport materials over great distances, we create machines that will do it for us. Science is our secret weapon, transforming problems into possibilities. However, science alone means little. If innovation dies with its creator, who does it help? Science must be communicated to others before it can make a difference in any meaningful way.
It would be incomplete to bestow language or science with the title of ‘the cornerstone of civilisation.’ It was science communication that really drove our development. And I don’t just mean this in the external sense. After all, is the transfer of genetic information from one generation to the next not science communication? What are we but a biological game of Chinese Whispers, the message mutating through each host but somehow continuing to make sense over millions of years?
The human race not only benefits greatly from science communication; we are the product of it. It is embedded into our biological and cultural history. Proof that it is not just knowledge but the sharing of knowledge that is the real root of power.
Unequal access to technology and the Internet is traditionally termed the ‘digital divide’. Both are expensive, which leaves some people behind. Today the situation has changed, with 98% of minors having home Internet access in Malta. Government targets digitally-deprived students by investing hefty sums to have tech at school. However, there is a new digital divide within formal education, and this time it is not about who uses technology but how they use it.
What is the attitude toward the technology that is being used in class? What is the goal that students are using that technology to accomplish? You can have countless schools on the receiving end of whole shipments of tablets and laptops, but the sad reality is that without an effective strategy, they are unlikely to reap the full benefits of that investment.
Dr Philip Bonanno
If technology is placed within a system that ignores students’ needs and is unresponsive, if not completely resistant, to new teaching and learning methods, the result is completely counterproductive. A teacher’s frustration with students being distracted by their devices is an everyday occurrence, and it needs to be addressed. The question is: Is this a technology-related problem or a more profound issue related to how humans discover and understand knowledge? Are these pedagogical conflicts arising from the presence of technology in class or from an epistemological clash between teachers’ and students’ beliefs about learning and knowledge sharing?
If we define pedagogy as ‘guidance for learning’, we need to provide guidance for a variety of learning methods. By focusing only on the ‘chalk-and-talk’ method of teaching delivery, we may actually limit access to different ways of acquiring knowledge. Besides using technology to enhance teaching, digital tools and resources need to be used to empower students: first to take over the management of their own learning, and second, to pursue different technology-enhanced learning avenues for acquiring, creating, and sharing knowledge. This gives the student better skills in digital and information (critical) literacy, in collaboration, and in networking, hence preparing them for the world of work.
To make this happen, challenges await both teachers and students. Teachers need to welcome new forms of learning, offering guidance and support rather than simply ‘giving students all the information they need to know.’ Students, on the other hand, have to overcome the mental conditioning that links learning directly to teaching so they can stand on their own two feet.
Students and teachers need to work together to adopt a more independent and customised approach to learning, enhanced and transformed through technology.

He decided to put the egg in an aquarium to see what would happen, and while the shark pup inside developed successfully over the course of a few weeks, it eventually died before the two month mark. Looking back, Nowell can confidently say now that it had everything to do with temperature.
While the initial plan for our interview was to go to the fish market and save the eggs still alive in the female sharks, a storm put an end to those plans. The fishermen couldn’t go out to sea, so we made our way to the Malta National Aquarium instead.
But there is more to Sharklab than the sharks themselves, Nowell notes. Towards the end of our trip to the aquarium, he highlights the need for better ecosystem management. ‘The animals, as fascinating as they are, live in an environment,’ he says. That itself deserves attention.
