Since the 1960s heavy fuel oil (HFO) has reigned supreme as the king of maritime fuels. It was efficient and cheap; its use spread far and wide. International shipping boomed on its success. Even today, this industry handles 90% of the world’s trade volume. For many, HFO is the lifeblood of the maritime shipping industry. But it has a dark side…
La Biennale di Venezia is the world’s biggest art event. Every two years, Venice erupts in a glorious art extravaganza as artists from all over the world descend on the city in celebration. This year marks the 57th edition of the International Art Exhibition. It also marks Malta’s return to the event. Emma Pettit tells us more.
Tourism has long been an integral part of the Maltese economy. But a big dose of change is sorely needed if we’re to keep the money coming in without selling our souls in the process. Julian Christopher Zarb explains why.
Not many Ph.D.s lead to a new programme of studies, but cardiac paediatrician Prof. Victor Grech’s did. His study on Infertility in Science Fiction inspired him and his supervisors, Prof. Ivan Callus and Prof. Clare Vassallo, (University of Malta) to start the HUMS programme: a space for researchers in the humanities, medicine, and sciences to meet and discuss the bridges between these areas.Continue reading
Ask any practitioner of the performing arts in Malta what their biggest cross to bear is, and a veritable list comes pouring out like burning lava. However, once you plough through the expected maladies that plague every small art scene—limited audiences, limited sources of funding available, unctuous reviews—in Malta, you’ll always arrive at this: a lack of viable spaces for productions and rehearsals.Continue reading
Thomas Huxley wrote, ‘The medieval university looked backwards; it professed to be a storehouse of old knowledge. The modern university looks forward, and is a factory of new knowledge.’ Continue reading
By Robert ZammitOne of the most common causes of total knee replacements is osteoarthritis, a disease which affects around 40% of Maltese senior citizens. The rise in age expectancy and obesity, compounded by injuries to patients, will see these numbers grow. All of this is expected to increase total knee replacement surgeries by 362% by the year 2030. The need for knee implants to have a longer lifetime is real.Continue reading
By Karl FiteniAn astronomer’s task is to provide insight into the nature of the universe through the observation of celestial objects. Stars are usually a few hundred, or even thousands, of light-years away—a problematic distance for direct study. Instead, people can study the light emitted by the star rather than the star itself.Continue reading
Triaxial testing rigs are used the world over to experiment on ground materials such as soils, rock, or powders. At the University of Malta (UoM), one such rig started being assembled in 2014 using existing equipment at the Faculty for the Built Environment, modernised with the help of the Faculty of Engineering. The rig is now complete, with plans to test rocks typically found in Malta, simulating the stresses created by big excavations and tall towers, steep slopes and deep underground tunnels.
The laboratory is used to investigate the engineering characteristics of weak ground materials such as clay, silt, sand, and weak rock (turbazz in Maltese building terminology). Space and economic pressures are pushing local buildings deeper and taller without the knowledge of how the local rocks can sustain the pressures created. Architects and engineers, now more than ever, are being asked to design excavations and buildings in these weak materials. Abandoning a site for a stronger one is now no longer an option. In-depth understanding of how ground materials behave, therefore, becomes fundamental if dangerous consequences are to be avoided.

The equipment is already being used to teach the next generation of architects and engineers. They now have the opportunity to experiment with the local ground materials. They can load them with imagined future buildings or unload them through simulated excavations, all the while observing the real-world effects.
The first real research effort is aimed at understanding what’s going on in Malta’s weak Globigerina limestone, which is currently loaded by heavy buildings. We need to be aware of their internal structure, the water within, how they crush and how long it takes. It’s likely to be a long story, but this is just the beginning.
