Mobile Air Quality Laboratory (MAQL)
The Mobile Air Quality Laboratory (MAQL) is the first of its kind on the Maltese Islands. Run by a team of geoscientists at the University of Malta, the MAQL can assess the quality of the air by continuously monitoring particulate and gaseous air toxics.
The particulates it can detect vary in size. The finer particles (PM1 and PM2.5) are usually the most dangerous respirable fraction but the instrumentation can also measure coarser sized particles (PM4 and PM10). The suite of gaseous pollutants that can be checked are sulfur dioxide, oxides of nitrogen, carbon monoxide, ozone, Volatile Organic Compounds (VOCs), organic and elemental carbon, and radon.

The MAQL is able to compare the air in indoor and outdoor spaces while recording meteorological conditions onsite. The comparison helps scientists understand from where the pollution originates. Is there so much pollution in our environs because of all the cars outside our window? Or is it because of the new sofa the family next door just bought? Or perhaps it is a result of the redecoration the building down the road recently underwent. Such data is vital for scientists to be able to figure out the root of a problem, to create a model of personal exposure to the pollutants, and to develop safer measures for the general public.
The MAQL facility will help scientists develop a clearer picture of the indoor air quality across the Maltese Islands. It will help other scientists interpret older data, and enable them to design new studies. Medics can match such data with population studies and assess disease rates around Malta. The MAQL can determine the sources of pollution inside buildings with the help of lifestyle and meteorological data, providing enough information for the construction of dwellings which have cleaner and safer air for everyone.

Time, Space, & the Ocean Wanders
As an archipelago, the Maltese Islands have been a hotspot for seabird nesting since time immemorial. Marie Claire Gatt talks about her research and a major EU project determining how to protect far travelling seabirds. Photography by Jean Claude Vancell.
The Hidden History of the Maltese Genome
By reading someone’s DNA one can tell how likely they are to develop a disease or whether they are related to the person sitting next to them. By reading a nation’s DNA one can understand why a population is more likely to develop a disease or how a population came to exist. Scott Wilcockson talks to Prof. Alex Felice, Dr Joseph Borg, and Clint Mizzi (University of Malta) about their latest project that aims to sequence the Maltese genome and what it might reveal about the origins and health of the Maltese people.
Heartbreakers
Every person possesses the same genes within every cell. Their DNA provides the information to first create an entire functioning body and then keep it running. While all humans share more than 99.9% of their DNA, it is the subtle differences in our DNA that ensure individuality. Many differences are superficial effects, like hair colour, but some can have disastrous health effects. Scott Wilcockson talks to Dr Stephanie Bezzina-Wettinger (Faculty of Health Sciences, University of Malta) about her research on these subtle differences and how they can contribute to heart attacks.
Sensory Apparatus
‘What does it really mean to sense something?’ That was the fundamental question Dr Libby Heaney (quantum physicist and artist) asked herself when she started working on Sensory Apparatus, currently on display at Blitz in Valletta. For almost a year she worked together with Bonamy Devas (artist and photographer) and Anna Ridler (designer working with information and data). For Libby sensing means the collection of data. Science tries to measure everything and is now through so-called ‘big data’ attempting to quantify subjective things, like happiness levels or the perfect online dating match.
Sensory Apparatus visualises the constant surveillance our data is under. In the first room a web of elastic black and white fibres represents a network of light and data. The experience of traversing the space and interacting with the structure is like simultaneously being sensed and sensing the internet. ‘Like the internet, you are missing out if you cannot make it past the first room’, Libby suggests.
The second room has circuit boards and speakers mounted to the walls. People curious enough will trigger a proximity sensor and a computerised voice starts talking. ‘Name. Country. Age. Address.’ What sounds like nonsense at first, quickly develops into the auditive representation of an algorithm. Passing consecutive speakers continuously reveals its different layers. These algorithms are complex programmes, designed to collect the footprints people leave while online. The information is used by marketers to direct and personalise adverts. ‘We wanted to reveal the technology. The actual objects represent the discussion we are trying to make.’
The last room is pitch black. Only when approaching the middle of the room a projector lights up, projecting advertisements directly onto people’s bodies. The commercial pieces, gathered from across Malta, follow every movement, change constantly and are reflected from the room’s glossy walls. At the exhibition opening, once people noticed they were being used as a billboard, they quickly moved away. ‘People change and behave differently in there’, Libby says, making it obvious how advertisements influence us online.
As a quantum physicist this change in behaviour reminded Libby of the Quantum Zeno effect, a phenomenon where an unstable particle will not decay while it is being observed. For Libby the concept of surveillance and the philosophy behind it led her to Sensory Apparatus. French philosopher Michel Foucault came up with the idea of panopticism, that inspired the exhibition. Panopticism is a social theory extending the panopticon, a prison designed to allow one person to observe all prisoners. Inmates would know they are possibly being observed, but could never be sure. This ultimately changes their behaviour. Sensory Apparatus’ first steps can be relived in the educational room near the artworks. The artists’ personal notes, inspiring articles, and other materials are laid out for everyone to explore.
The free exhibition opens every Tuesday–Thursday from 10am–3pm and Friday–Saturday from 3–7pm at Blitz, 68 St Lucia Street, Valletta, until April 6. For more information see thisisblitz.com
