Maniac: Two films. Two reviewers.

Noel: I recently saw William Lustig’s Maniac (1980) and Franck Khalfoun’s 2012 remake back-to-back. The latter is rather faithful to the original’s spirit. Frank Zito (played by Joe Spinell [1980] and Elijah Wood [2012]) is more of a textbook psychopath, and more brutal in Khalfoun’s film; but still remains faithful to its source.

Krista: I thought the first’s ‘rawness’ was more brutal. The second had a polished style despite the first person perspective. The 1980 film was grittier.

N: True. The remake looks slicker. For instance, the murder scenes are meticulously choreographed, operatic even. Lustig’s film is truer to life, scarier too, because in his lucid moments the killer acts normal.

K: The first person perspective didn’t convince me. Eventually I even forgot about it till it suddenly jumped to the fore again. It was inconsistent and uneasy without being very unsettling. It reminded me of Peeping Tom (1960), which made better use of the first person perspective.

N: Agree, but it didn’t distract me.

K: I hoped it would be more ‘distracting’. It would have been preferable if the first person perspective had been more defamiliarising, puncturing the viewer’s comfort zone — rather than just being ‘naturalised’.

N: The subjective point of view didn’t help me to get closer to the killer. I only saw this technique being used effectively in Enter the Void (2009). I find it a bit distracting because it can turn into a weird game (Spot the reflection in the mirror!). That said, in Maniac they were well aware of this and tried to have fun with it. The moments when the film veers away from the first person perspective, it sort of clicks into another gear.

K: Good point about the first person perspective being the default here, and the veering away from it becoming a ‘moment’ in itself. It calls to mind Bret Easton Ellis’ book American Psycho (1991).

N: I liked the fact that the remake created a deeper relationship between Frank and the mannequins. They are more than just a manifestation of his childhood trauma — a dysfunctional, promiscuous mother. The restoration of the mannequins is a genuine labour of love which underscores the affection that he nurtures towards the photographer (Anna, played by Nora Arnezeder). She is a mediocre artist unable to hold her camera properly. Frank is the real deal, getting his hands dirty.

K: That’s a well-noted criticism of the photographer. In the first movie, I couldn’t really ‘judge’ whether she was a good artist or not — there wasn’t a focus on her art, instead they showed the world she moves around in, which made me think she was a budding artist. In the second one she’s portrayed as an underwhelming artist. She tries to use the mannequins to underpin her art and to somehow appropriate his by projecting an image of her face onto their blank heads.

N: Besides Anna, two other victims in Khalfoun’s film are a dancer and an agent. In both murders the director abandons the first person perspective, suggesting that either Frank is seeing his actions as a form of art, or that we, the audience, should see Frank himself as a work of art.

K: Yes, perhaps even perverting the sublime into the brutally grotesque. Yet ‘getting his hands dirty’ is counterpoised by the film’s stylishness.

N: So which is better?

K: Both films ultimately do different things. This is down to stylistic differences, enjoyably the remake doesn’t try to ‘replace’ Lustig’s film.

N: Totally agree. They’re like brothers sharing one (hell of a disturbed)
mother, similar yet so different. •

Does Alcohol kill brain cells?

This myth is HUGE! Urban legend says that drinking kills cells, some even say: ‘three beers kill 10,000 brain cells.’ Thankfully, they are wrong.

In microbiology labs, a 70% alcohol 30% water mix is used to clean surfaces pretty efficiently. It seems our neurons are made of sturdier stuff.

Alcohol does affect brain cells. Everyone knows that and it isn’t pretty. Alcohol can damage dendrites, which are delicate neural extensions that usually convey signals to other neurons. Damaging them prevents information travelling from one neuron to another — a problem. Luckily, the damage isn’t permanent.

Treating stone to save Maltese Culture

Malta has three UNESCO world heritage sites which need constant conservation. Generally, it is better to preserve the original building material than replace it. The conservation method called consolidation can glue deteriorating stone material to the underlying healthy stone maintaining it, but few consolidants have been tested on local Globigerina limestone. Sophie Briffa (supervised by Daniel Vella) tested a new set of consolidants which are stronger than other compounds but affected the colour of the stone. She applied five different conditions on the stone. The first three were novel treatments. They were based on a hybrid silane (tetraethylorthosilicate (TEOS) and 3-(glycidoxypropyl)trimethoxysilane (GPTMS)) but one had nanoparticles, one had modified nanoparticles, and the other lacked them. The fourth was a simple laboratory-prepared TEOS silane. The fifth was untreated limestone samples for comparison.

The treatments successfully penetrated the stone’s surface. Microscopy coupled with other techniques including mercury intrusion porosimetry carried out in Cadiz, Spain, confirmed this infiltration and the stone’s physical qualities: strength, drilling resistance, and so on. Half of the treated stones underwent accelerated weathering. The consolidants with nanoparticles or modified nanoparticles were stronger than the other treatments. They also maintained the original surface colour and improved the stones’ ability to absorb water. On the other hand, they were less resistant to salt crystallisation that can damage the stone making it brittle.
The best consolidant for Maltese stone has not yet been found. Ideally, it should have a good penetration and good weathering properties that preserve the stone’s appearance. It should allow ‘breathability’ and be reversible. Current stone consolidation techniques are irreversible since they permanently introduce new material into the stone. These are only acceptable since consolidation is a last attempt to save the stone before complete replacement.

French writer Victor Hugo summed up the importance of this research when he said, ‘Whatever may be the future of architecture, in whatever manner our young architects may one day solve the question of their art, let us, while waiting for new monuments, preserve the ancient monuments. Let us… inspire the nation with a love for national architecture’.

This research was performed as part of an M.Sc. in Mechanical Engineering at the Faculty of Engineering. The research was funded by the Strategic Educational Pathways Scholarship (Malta).

Logical chemicals

Chemistry is not usually associated with logic gates, sensors, and circuits. However, a new breed of chemist — the molecular engineer — is adding a bit of chemical spice to them. Given the right tools, his/her hands can synthesize anything, from molecules that assemble into large structures to others that can display information about their environment.

Thomas Farrugia (supervised by Dr David Magri), created a molecule that could be toggled between an ON and OFF state using AND Logic. AND logic means that it needs two chemicals to switch state, adding just one chemical makes no difference. The states are easily recognised by shining UV light on the molecule since only the ON state produces blue light.

In the OFF state, the movement of electrons from two input sites prevents light being released. Stopping the electron transfer enables light release. The blue light shines when specific chemicals bind to the two input sites. The chemicals use up the electrons being transferred, letting the output of the molecule absorb UV light and shine blue light.

The two chemicals added were an acid and an iron (III) source (like what is found in rust). The acid provides hydrogen ions that bind to the nitrogen atom, whilst the iron (III) ions attack the molecule’s iron (II) atom (pictured as Fe). The molecule displays AND logic since it needs both the acid and iron (III) to turn on light emission.

The molecule was synthesised using a one step reaction and tested to determine the strength of the ON and OFF signals. Testing by fluoresence spectroscopy is essential to determine whether it would make a viable sensor, since the technique compares the strength of the ON and OFF state. The molecule will only work well if there is a large difference between the different states, since a machine needs to detect the change.

This molecule can sense the extent of acidity and iron (III) ions in a solution, and convey that information using light, which is easily measured. The molecule’s design could also be integrated into bigger and more complicated molecules so as to carry out other logical and mathematical operations using chemicals. These molecules are a step towards chemical computers.

This research was performed as part of a B.Sc. (Hons) Chemistry with Materials at the Faculty of Science.

Finding bats by listening

Sonar for navigation was implemented after the Titanic disaster in 1912. Bats have used this remarkable technique for the past 50 million years. These nocturnal animals emit ultrasonic signals and analyse the returning echoes to avoid obstacles or predators and find their prey. For humans, studying bats means long hours in the night spent tracking their movements or capturing them with nets. To avoid some of the bat research difficulties, conservation researchers identify and study bats by eavesdropping on the ultrasonic sounds they emit.
Clare Marie Mifsud (supervised by Dr Adriana Vella) has now studied bats in Malta linking specific sound patterns to specific bat species and their behaviour. Bats can be identified using acoustic detection because they all use different frequency patterns to suit their needs. The analyses can be used for further research and conservation monitoring of local bats.

Her study encompasses 38 research survey sites spread all over the Maltese Islands. Two bat detectors (a heterodyne and a real-time expansion detector) are used simultaneously to instantly identify and analyse the species. Nine different bat species are already confirmed to inhabit the Maltese Islands till now.
Three species (Rhinolophus hipposideros, Myotis punicus, and Plecotus austriacus) were recorded a few times (2% of survey time), since they use low intensity echolocation signals. Other bat species (Hypsugo savii, Pipistrellus pipistrellus, Pipistrellus kuhlii, and Pipistrellus pygmaeus) were detected more often (92% of survey time). All Maltese bats feed on insects and are found to spend most of their time in valleys followed by other habitats including cliffs, woodlands, agricultural land, shrublands and urban settlements. Valley biodiversity is important for local bat survival and needs to be preserved.
Through the use of bat acoustic detection systems and signal analyses, this detailed research is providing the first important set of data of its kind for all bat species detected in the Maltese Islands. This complements other bat research which has been ongoing since 1998 by the Conservation Biology Research Group (University of Malta). They have been involved in different bat studies including the ecology and genetics of local bat populations. These research efforts aim at reversing the trend of decreasing bat numbers. Mifsud’s research paves the way towards developing another effective long-term monitoring tool for the conservation of bats in Malta.

This research is part of an M.Sc. in Biology at the Faculty of Science. BICREF (The Biological Conservation Research Foundation) provided voluntary assistance during field work. The research was partially funded by the Strategic Educational Pathways Scholarship (Malta). This Scholarship is part-financed by the European Union – European Social Fund (ESF) under Operational Programme II – Cohesion Policy 2007-2013, ‘Empowering People for More Jobs and a Better Quality Of Life’.

The key to networking

I first heard about COST (European Cooperation in Science and Technology, a networking platform for scientists www.cost.eu) way back in 1996 during a pharmacokinetics meeting in Athens. Some participants mentioned that their attendance had been funded by COST. So on my return I contacted the Malta Council of Science and Technology to try and obtain more information. When I learnt that COST funds EU networking I quickly applied to become a member of a COST action (this is what COST calls a network). After bureaucratic leaps and bounds I become Malta’s representative on a COST action. It certainly opened new horizons to me and the networks I formed with top researchers in Europe were unique.

By 2010 my enthusiasm resulted in MCST nominating me as Malta national contact point for COST. It has been of huge satisfaction that in these three brief years Malta’s participation has risen from 6 actions to over 100. Over 150 Maltese researchers take part in COST.

Why is COST so important for Malta?

The complaint I hear most often in Malta, not only in academic circles but also among SMEs (small to medium enterprises), is that research in science is only for the elite, that it is too high brow and that it is not relevant to Malta. COST proves otherwise. What else could link disaster bioethics, to colour and space in cultural heritage to the comparison of European prostitution policies, with submerged prehistoric archaeology? Other links include the quality of suburban building stocks, integrated fire engineering and response, and language impairment in a multilingual society. COST also funds networks across a whole spectrum of research from the humanities to the fundamental sciences including string theory to childbirth in various cultures.

Participating in a COST action involves very simple administrative and funding procedures. For once, our small size is an added advantage since every COST country is allowed to nominate two members to participate in each action, putting Malta COST researchers at par with researchers from much larger countries. Achieving these results has not been easy, since many researchers hesitate and require persistent prodding. There are frequent reminders and one to one meetings to persuade them to participate. It has been a real eye-opener meeting researchers in Malta from different disciplines and learning about their research.

Deciding to participate in COST may seem a small step to some, an added administrative burden to others, while some see it as another travel commitment. COST offers the response to the conundrum of how to overcome our physical (and perhaps in some instances also mental) insularity. You should not let this opportunity pass…

Hotline Miami

Push start. Grab a weapon. Get shot. Repeat… ad infinitum. ‘Punishing’ hardly describes a session of Hotline Miami. Typically, within 10 seconds you could die three or four times. It is just as frustrating as it is challenging. Addictively, you will not give up until you pass that sneaky little passage.

Hotline Miami is an ultra-violent, psychotic game, where your only aim is to kill all the ‘bad guys’.

Yet, every little move counts, and deciding which weapons to use or which door to open first will reveal the deep strategic possibilities of the game’s intense experience. As you make your way through a pile of corpses, the suspense builds up to unbearable levels as you risk losing all in-game progress for just a little mistake. The massacre is only interrupted by brief moments that reveal details of our mysterious ‘hero’s’ back-story. Keeping true to expectation, even these interludes are awkward if not disturbing, and hardly shed light on our displaced, faceless avatar.

The excellent game tops it all with an irresistible ‘80s aesthetics and a neurotic electronic soundtrack. You’ll quickly find out why this game has stolen the show winning so many awards, and has hooked fans of Grand Theft Auto and of good old shoot’em up games. Hotline Miami is a joy in repetition, providing that being stuck in a Clockwork Orange–like scenario is your idea of joy.
