Following the herd: and why my world is getting smaller


he comments section of online news sites is intended to be a place where everyone can express their own opinion. But according to a study published in the journal Science, many people are heavily influenced by the positive opinions of others in such outlets, while less swayed by the negative ones. In order to see how perceptions of favourability affected people’s judgement about others’ comments, the researchers randomly altered the favourability ratings of 101,281 different comments. Through this approach, they could see how readers evaluated the same comments when those comments were given different ratings. They found that comments whose ratings were manipulated in a favourable direction saw their popularity snowball, becoming 32% more likely than untreated comments to receive a favourable rating from the next viewer of those comments and 30% more likely than untreated comments to obtain a very high favourable rating. The researchers said this “created accumulating positive herding that increased final ratings by 25% on average”. So what does this mean for me? While the researchers manipulated the ratings for their own ends, other parties with less well-meaning intentions may do the same, such as political operatives, marketers or anyone who stands to profit by creating an exaggerated appearance of popularity.  And then I’ll more than likely be taken in with the deception. Mate this effect with Amazon. Amazon regularly suggests books that it has calculated will appeal to me. All of these suggestions come with popularity ratings. If I select my reading material from these suggestions and choose the more popular offerings, my reading world becomes narrower and narrower. Once upon a time I walked into a bookshop or library and saw lots of titles - not just the ones that were supposed to appeal to me. Sometimes I selected different genres and the very act of choosing broadened my horizons. But now I am being categorised into a smaller and smaller box and I don’t like it. So I am suggesting all scientists confound the crowd-based opinion statisticians by refusing to follow the herd.

New imaging system uses unconventional way of focusing light 6

WHAT’S NEW IN LAB & LIFE SCIENCES - October/November 2013

For hundreds of years, optical devices like microscopes and telescopes have relied on solid lenses that slide up and down to magnify and to focus. In pursuit of ever-smaller imaging systems, researchers are now working to create entirely unconventional ways of focusing light.


o tune how much light is received, conventional devices use mechanical contraptions like the blades that form the adjustable aperture in cameras. Now engineers from the University of Freiburg in Germany have built a novel type of imaging system inspired by the elegance and relative mechanical simplicity of the human eye. The technology may one day lead to new imaging instruments and microscopes for use in medicine and scientific research, such as devices for detecting early signs of skin cancer or early visual cues for food spoilage. The new imaging system is the first to demonstrate the imaging capabilities of some of these unusual focusing techniques by replacing conventional, solid lenses with the combination of a malleable lens and a liquid iris-like component. And, the researchers report, their device focuses light almost as well as its biological counterpart in people. They described their new imaging system in a paper published in The Optical Society’s (OSA) journal Optics Letters. Though the image processing that happens in the human brain and eye is complex, the mechanical apparatus is relatively simple. It consists of muscles that deform a stretchable lens to change the focal length, the distance between the lens and the point at which rays of light are brought to a focus. The eye’s iris opens and closes to control the amount of light that can pass through the lens. But as engineers try to shrink the size and expand the capabilities of these instruments, the imaging systems they create become overly complex and expensive. Instead of using complicated mechanisms that require moving parts to tune the focus and adjust the aperture, the Freiburg researchers looked to the eye. “What we’re doing now is a completely different means of doing the tuning,” said Hans Zappe, the Gisela and Erwin Sick Professor of Micro-optics at the University of Freiburg and co-author of the paper. For their new device, the researchers used two imaging elements that they had demonstrated previously but had never

combined into a single system. They made a lens of silicone surrounded by several miniaturised motors that adjust the focus by deforming the lens. “You can squeeze and stretch it just like your eye squeezes and stretches its lens to adjust its focal length,” Zappe explained. In front of the lens they included an irislike component, which contains two liquids enclosed in a single flat chamber. One liquid is opaque and surrounds the clear liquid, forming what looks like a donut of black ink. Because the clear liquid is oil based while the dark liquid is water based, they stay separated. And since both liquids have exactly the same density, they remain in place even if you shake or rotate the device. Applying an electrical voltage to these liquids changes some of their properties, such as the way a droplet beads up on a surface. This behaviour, called electrowetting, allowed the researchers to manipulate the liquid, expanding and contracting the dark ring to let in more or less light through the clear liquid at the centre. Zappe and his team have tested and characterised the optics of their device in detail, analysing how much it would distort an image. Each of the two main components - the iris-like liquids and the deformable lens - can be designed to compensate for any aberrations in the other, resulting in better optical quality than would be expected if you were to consider the two components separately, Zappe said. While the new device may not be as good as the best conventional visual imagers, it is state of the art for a tunable lens, he said. The cylindrical device described in the new paper is roughly three centimetres in diameter and five centimetres long, and although the researchers plan to shrink the design a bit more, making a miniature version isn’t their primary goal, since optical quality is inherently limited with smaller sizes. Instead, Zappe said, they hope to add more functionality. “What we’re looking at is to make really high-quality images where we have the ability to image things that a normal person wouldn’t be able to see,” he explained.

Through-focus scanning optical microscopy A technique developed several years ago at the National Institute of Standards and Technology (NIST) for improving optical microscopes has now been applied to monitoring the next generation of computer chip circuit components, potentially providing the semiconductor industry with a crucial tool for improving chips for the next decade or more.


he technique, called through-focus scanning optical microscopy (TSOM), has now been shown able to detect tiny differences in the three-dimensional shapes of circuit components which, until very recently, have been essentially two-dimensional objects. TSOM is sensitive to features that are as small as 10 nanometers (nm) across, perhaps smaller - addressing some important industry measurement challenges for the near future for manufacturing process control and helping maintain the viability of optical microscopy in electronics manufacturing. For decades, computer chips have resembled city maps in which components are essentially flat. But as designers strive to pack more components onto chips, they have reached the same conclusion as city planners: The only direction left to build is upwards. New generations of chips feature 3D structures that stack components atop one another, but ensuring these components are all made to the right shapes and sizes requires a whole new dimension - literally - of measurement capability. "Previously, all we needed to do was show we could accurately measure the width of a line a certain number of nanometres across," explains NIST’s Ravikiran Attota. "Now, we will need to measure all sides of a three-dimensional structure that has more nooks and crannies than many modern buildings. And the nature of light makes that difficult." Part of the trouble is that components now are growing so small that a light beam can't quite get at them. Optical microscopes are normally limited to features larger than about half the wavelength


of the light used - about 250 nm for green light. So microscopists have worked around the issue by lining up a bunch of identical components at regular distances apart and observing how light scatters off the group and fitting the data with optical models to determine the dimensions. But these optical measurements, as currently used in manufacturing, have great difficulty measuring newer 3D structures. Other non-optical methods of imaging, such as scanning probe microscopy, are expensive and slow, so the NIST team decided to test the abilities of TSOM, a technique that Attota played a major role in developing. The method uses a conventional optical microscope but, rather than taking a single image, it collects 2D images at different focal positions forming a 3D data space. A computer then extracts brightness profiles from these multiple out-of-focus images and uses the differences between them to construct the TSOM image. The TSOM images it provides are somewhat abstract, but the differences between them are still clear enough to infer minute shape differences in the measured structures - bypassing the use of optical models, which introduce complexities that industry must face. “Our simulation studies show that TSOM might measure features as small as 10 nm or smaller, which would be enough for the semiconductor industry for another decade,” Attota says. “And we can look at anything with TSOM, not just circuits. It could become useful to any field where 3D shape analysis of tiny objects is needed.”

Immunoassay platform Cira by Aushon is an immunoassay platform that combines productivity with precision. It has the consistency of singleplex ELISA while delivering on the throughput and increased sensitivity of multiplexing. The product features several synergistic improvements. Cirascan combines astronomy-grade imaging with sophisticated Cirasoft software to enhance signal-to-noise ratio by analysing only the precise coordinates of the spots, thus improving sensitivity and dynamic range. Ciraplex assays have up to 12 analytes per well, printed in circular pattern by the company’s ultraprecise microarray printer. This geometry avoids the ‘black hole’ of lower signal in the centre of each well, leveraging static and dynamic fluid properties to provide consistent incubation on all 12 spots with low sample volume. As a result, Ciraplex can offer sensitivity greater than ELISA and high reproducibility in a multiplexing format. Cirareports summarises multiplate studies simply and quickly.

Biomolecule engineering with nanoparticle tracking analysis Particle & Surface Sciences has reported on how nanoparticle tracking analysis (NTA), from NanoSight UK, is being used in the research project ‘Engineering of Biomolecules’ at Lorraine University, based in Nancy. Dr Jordane Jasniewski works at the Laboratory of Biomolecules Engineering (LIBio) at Lorraine University and teaches in Food Chemistry at ENSAIA, an engineering school. He is a member of the research team working on the engineering of biomolecules to understand their structure and function to help develop new molecular architectures, to be applied in the areas of foods and agrichemicals, nutrition, pharmacology and cosmetics. The expertise of LIBio allows the study of stabilisation, functionalisation and targeting of active molecules such as probiotics, antibacterial peptides, phenolic antioxidants and polyunsaturated fatty acids (PUFAs). Based on vectors of rich marine DHA (docosahexaenoic acid, an omega-3 fatty acid), new dairy matrices, phospholipids and biopolymers are being developed. Dr Jasniewski described the reasons for his selection of NTA for the measurement of the hydrodynamic diameter, Dh, of his nanoemulsion samples. “Our samples, which include polysaccharides, milk proteins and lecithins, are polydisperse. Having used dynamic light scattering, DLS, without success, we decided on NTA as it makes measurements on a particle-by-particle basis and does not need the refractive index to determine Dh. We can also readily measure the concentration of our samples and data is produced in a convenient way to export and use for further study.” Particle & Surface Sciences Pty Ltd Contact info and more items like this at

Why taller people are smarter On average, taller people tend to be slightly smarter. The modest correlation between height and IQ has been documented in multiple studies stretching back to the 1970s. But the reasons for the relationship between the two traits have not been well understood.


esearchers at the University of Colorado Boulder have been investigating this phenomenon using twins and their families and have found that two factors are involved - the same genes affect both height and brain power and taller people are more likely than average to mate with smarter people. The study did not find that environmental factors contributed to the connection between being taller and being smarter, both traits that people tend to find attractive. The technique developed by the researchers to tease out those reasons may open the door for scientists to better understand why other sexually selected traits - characteristics that individuals find desirable in mates - tend to be linked. People who are attractive because of one trait tend to have other attractive traits as well. “Not just in humans but also in animals, you see that traits that are sexually attractive tend to be correlated,” said Matthew Keller, assistant professor of psychology and neuroscience at CU-Boulder and lead author of the study appearing in the journal PLOS Genetics. “So if you have animals that are high on one sexually selected trait they are often high on other ones, too. And the question has always been, ‘What’s the cause of that?’ And it has always been very difficult to tease apart the two potential genetic reasons that those could be related.” The key to the technique developed by Keller, also a fellow at CU-Boulder’s Institute for Behavioral Genetics, and his colleagues is using data collected about fraternal twins, identical twins and, importantly, their parents.

It has been common in the past to use information about identical twins and fraternal twins to determine whether a particular trait is inherited, caused by environmental factors or affected by some combination of both. This kind of twin study assumes that each twin grows up with the same environmental factors as his or her sibling. If a trait that’s present in one twin is just as often present in the other - regardless of whether the twins are fraternal or identical - then the trait is likely caused by environmental conditions. On the other hand, if a trait is generally found in both identical twins but only in one of a set of fraternal twins, it’s likely that the trait is inherited, since identical twins have the same genetic material but fraternal twins do not. Similar studies also can be done for linked traits, such as height and IQ. But while scientists could determine that a pair of traits is passed down genetically, they could not further resolve whether inherited traits were linked due to the same genes influencing both traits, called ‘pleiotropy’, or because people who have those traits are more likely to mate with each other, known as ‘assortative mating’. The latest CU-Boulder study solves this problem by including the parents of twins in its analysis. While this has occasionally been done in the past for single traits, information on parents has not previously been used to shed light on why two traits are genetically correlated. In part, that’s because existing twin registries, where information for heritability studies is drawn, don’t often contain information on the parents.

WHAT’S NEW IN LAB & LIFE SCIENCES - October/November 2013



Additionally, creating the computer programs that are necessary to crunch the data for multiple traits from twins and their parents in order to understand environmental effects and both types of genetic effects is difficult. “These designs have never taken off because they’re very difficult to code,” Keller said. “It’s a challenge. They’re very complicated models.” For this study, the research team used data collected from 7905 individuals - including twins and their parents - by the Colorado Twin Registry at CU-Boulder and the Queensland Twin Registry at the Queensland Institute of Medical Research in Australia. Keller and his colleagues found that for the twins in their study, the correlation between height and IQ was not impacted by environmental conditions. Though Keller cautions that in societies where there is more nutritional variation among families, environmental factors could come into play.

The research team found that pleiotropy and assortative mating were about equally responsible for the genetic connection between height and IQ. “It does look like there are genes that influence both height and IQ,” Keller said. “At the same time, it also looks like people who are taller are slightly more likely to choose mates who are smarter and vice versa. Such mate choice causes ‘IQ genes’ and ‘tall genes’ to become statistically associated with one another. There are a lot of exceptions, but there’s a statistical relationship that does happen more than would be expected by chance.” Now that the CU-Boulder team has built a computer model that is capable of disentangling the causes for linked traits, Keller said he hopes twin registries will begin to collect more data from parents and that other people in the field take advantage of the model.

Single analyte microarray Q-Plex Singleplex assays are single analyte microarrays used to measure a range of human cytokines. The kits adopt high dynamic range (HDR) technology to measure a significantly greater quantifiable range compared to traditional ELISAs. HDR technology involves the use of antibodies optimised for highand low-range measurement of specific analytes. The antibodies are printed in planar arrays at the bottom of each microplate well, along with a reference spot for convenient imaging. QView Software combines the data from all the microspots using a proprietary algorithm based on five-parameter logistic regression modelling. This ensures quality analyte readings with maximum low-end sensitivity and peak high-end quantification. Kits are efficient and easy to run, requiring only 50 µL per sample and using a protocol similar to traditional ELISAs. The expanded range across the standard curve means fewer dilutions per sample; better sensitivity than traditional ELISAs to capture low analyte levels; and the higher end range captures data for concentrated samples. The intra-well precision from replicate microspots also provides greater surety of results. Sapphire Bioscience Contact info and more items like this at

Automated colony counter speeds up vaccine testing Synbiosis, a manufacturer of automated microbiological systems, has announced that its ProtoCOL 3 automated colony counter is being successfully used at UK vaccine company ImmunoBiology (ImmBio) in Cambridge to speed up testing throughput of its bacterial meningitis vaccines. The purchase of the ProtoCOL 3 by ImmBio is supported by a research and development grant from the Technology Strategy Board as part of the government-backed Biomedical Catalyst. The scientists are using it to count thousands of small colonies of Neisseria meningitidis plated out post serum bactericidal assay (SBA). The ProtoCOL 3 is helping the researchers to rapidly determine the efficacy of new vaccines against bacterial meningitis. Claire Entwisle, Head of Laboratory at ImmBio, explained: “Regulatory requirements mean we have to use an SBA test to establish vaccine efficacy and, since we are testing a number of different prototype vaccines, we count around 100-150 colonies in each of eight streaks on a square SBA plate. We have around 70 of these plates to count every week so this would be timeconsuming and difficult to maintain consistency of results if we did it manually. We visited the NIBSC [National Institute for Biological Standards and Control] to see what their scientists used to quality assure bacterial vaccines. That’s when we saw the ProtoCOL software and knew this would help us speed up our testing efforts. “The ProtoCOL 3 is manufactured in Cambridge, giving us added confidence, and the system comes with a specific software program for analysing SBA plates, both of which swayed our decision to purchase the ProtoCOL 3 for our work. For us, the benefits of using the system are saving time, as well as accuracy and consistency of count. Many of our colonies are very close together or touching and the software copes well with interpreting these. We are so pleased with the way the ProtoCOL 3 performs that we even intend to use it in future for the more difficult application of counting Streptococcus pneumoniae colonies on blood agar plates as we know that the lighting options on the ProtoCOL 3 will allow us to distinguish and count the almost opaque red colonies on a red background.” Martin Smith at Synbiosis commented: “Bacterial meningitis is a serious illness and we’re delighted to hear the ProtoCOL 3 is helping scientists at this innovative Cambridge vaccine company to help improve the productivity of their important vaccine trials. The ProtoCOL 3 system’s unique lighting and software combination has been developed over a decade until it is now widely acknowledged internationally as the leading technology for post SBA colony count analysis. The studies at ImmBio further demonstrate how adding a ProtoCOL 3 automated colony counter to an SBA workflow can significantly speed up the development of novel bacterial vaccines.” Don Whitley Scientific Pty Limited Contact info and more items like this at

Six tips for selecting a laboratory workstation

James Anderson*

Buying technician workstations for your laboratory is a major capital expense, deserving of careful consideration to avoid making a costly mistake. The choice can be complicated and there are a number of factors that you should consider. The key ones include initial purchase price, long-term ownership cost, laboratory layout and workstation design, supplier support services and flexibility. This last one is especially tricky, since it requires a bit of a crystal ball to make sure your choice supports changing laboratory environments, due to expansion and consolidation, as well as changing trends in equipment design and usage.


ollow these six tips for selecting a laboratory workstation that meets all your current needs, while positioning you to adapt to whatever comes down the parkway.

1. Count up all the costs - not just the obvious ones Be sure to factor in all related costs - don’t just look at the bottom line for the workstation. To the purchase price you should add shipping costs; installation costs; time, cost and complexity of adjusting individual workstations; costs for addon accessories (eg, shelves, storage, and tool and equipment holders); reconfiguration costs (should you want to convert single-sided workstations to double-sided in future); and, of course, the expected lifetime of the product and the need to replace it. Consider how you might be able to reduce your floor space requirements (and costs) by maximising your use of vertical space, which minimises the workstation footprint.

2. Consider your future business plans Are you planning to expand, reorganise or relocate? Changes in processes and techniques also may mean changing workstation layout, so consider modular, movable furnishings that can be easily expanded or rearranged. If you are located in a rented or

leased space, built-in workstations may limit flexibility and result in additional costs for repairing walls and floors if you move.

3. Pay careful attention to ergonomics A comfortable employee is a productive employee. Laboratories can sometimes be the source of repetitive strain injuries (RSIs), which result in musculoskeletal disorders (MSDs) such as carpal tunnel syndrome. The number one factor in addressing these ergonomic concerns is selecting equipment that allows employees to rearrange and adjust workstation elements easily. Technicians come in all shapes and sizes, so make sure they can raise, lower or change the tilt angle of workstation shelves; add or remove shelves; change the height or tilt angle of work surfaces; change the height or direction of lighting; raise or lower the height of footrests; and mount or relocate tools, equipment and storage on either side of a workstation. Figure 1 is a graphic illustrating the preferred horizontal and vertical reach zones you should work with.

4. Consider how your laboratory will adapt to changing equipment use In recent years, the equipment used to execute essential tasks in laboratories has been changing dramatically. None of us has the proverbial crystal ball, but before putting down your hard-earned

dollars on a workstation, review this list of laboratory trends and try to determine which items may affect your operations. Then make sure the workstation you select can support them. • Increased use of high-speed electric and air hand tools • Central suction featuring variable port control • Laser welding replacing soldering • Vacuum-pressure induction casting • I ncreased use of computers featuring scanning and CAD systems • 3D printing (also known as additive manufacturing) technology

Avoid workstations designed around a single task or process, and instead opt for workstations that can address different applications within the laboratory. A flexible, modular design with common, interchangeable components and with provisions to accommodate a wide variety of work surfaces, drawers, shelves and other accessories can be used in a variety of departments and for numerous functions.

5. Build in flexibility

A reliable supplier can be your partner in selecting the right workstation. For laboratories that operate from multiple locations, be sure the supplier has support branches near all locations. Ask about support services, such as laboratory layout and design, ability to customise purchased products, installation services and training.

We discussed earlier the importance of making sure your laboratory adequately considers your future plans, but flexibility is so important that it deserves its own tip. Your workstations should be able to support any major layout redesign due to expansion, the changing nature of the work or departmental reorganisation. Don’t let your workstations present an obstacle to growth. Truly modular and flexible workstations permit a variety of layout designs by sharing interchangeable components. Your choices include inline, back-to-back, L, C or X configurations. Having said that, when building in flexibility, always keep in mind conversion costs associated with changing workstation layouts. Achieving flexibility without discarding parts you’ve already invested in is your goal. Figure 2 is an example of a Lista Modular Technician workstation that can be used for a variety of tasks.

Online rheometer for food products The OnLine Rheometer (OLR) continuously measures, plots and reports the flow properties of liquids in process pipes. It assists process monitoring, process control and quality control of liquids in the processing and manufacturing of food products. Flow properties that influence processability or mouthfeel like viscosity, tack, elasticity and body are important for a variety of products in the food industry. The OLR is able to make measurements that directly relate to these variables and provide feedback to the operator in real time. The operator can thus make informed process decisions about the quality of the material in the pipe and make changes as appropriate. The product can reduce or remove waiting times associated with laboratory testing, removing production bottlenecks and increasing effective production capacity. Consumer-critical parameters such as mouthfeel can be monitored online so that satisfaction with the final product can be better assured during production rather than post-production from a taste panel assessment.

Uncovering the best cab sav clones The local wine industry and consumers will both benefit following research to identify differences in the top cabernet sauvignon grape clones.


lthough the wines we drink today are from very similar varieties to those produced in Roman times, the varieties are not exactly the same. Subtle changes accumulate silently through generations of propagation. Now the wine industry is exploiting these differences to its advantage. Cutting-edge technology is being used by researchers at The University of Western Australia and Department of Agriculture and Food (DAFWA) to plot the sites of genes along chromosomes. Assistant Professor Michael Considine, researcher with DAFWA and University of Western Australia’s School of Plant Biology, is coordinating the joint project. Different forms within a variety are known as clones, and some leading French wine clones are sold worldwide under trademark protection. Until now, researchers could only speculate on the identity of different clones, but according to Considine, “New technology is now allowing us to plot precise changes that occur in clones and take advantage of new changes that benefit the wine industry and consumers. “Differences observed in the vineyard may be due to one or more influences on the DNA - whether a single DNA mutation or through decorations on the DNA, chimeric mutations or the influence of viruses.

“We now have the technology to distinguish these effects and, thanks to our industry partners, can make an important contribution to the Australian wine industry and benefit consumers.” Considine said wine producers would benefit from the outcomes of the research through improved crop management and productivity, and the selection of elite clones to suit grower requirements such as early ripening or the production of high-value wines. Consumers would also benefit from an improved range of wine choice and consistency, and the development of high-value wines. Cabernet sauvignon was chosen for the research because it is one of the Australian wine industry’s ‘regional heroes’ and a popular red wine variety. The project will apply cutting-edge techniques in genomics to several clones on which extensive knowledge is already available from Western Australian and South Australian improvement programs. In addition to the genomic component, the project will include vineyard studies. The three-year project has received total funding of $574,000 from the Australian Research Council. The research is supported by 24 companies represented by the WA Vine Improvement Association, prominent national retailer Yalumba and the Australian Wine Research Institute.

Making hydrogenation greener Instead of relying on heavy metals as catalysts, researchers have discovered a way to use iron which will make the process of hydrogenation both more environmentally friendly and less expensive.


esearchers from McGill University, Riken and the Institute for Molecular Science have discovered a way to make the widely used chemical process of hydrogenation more environmentally friendly - and less expensive. Hydrogenation is used in a wide range of industrial applications, from food products, such as margarine, to petrochemicals and pharmaceuticals. The process typically involves the use of heavy metals, such as palladium or platinum, to catalyse the chemical reaction. While these metals are very efficient catalysts, they are also non-renewable, costly and subject to sharp price fluctuations on international markets. Because these metals are also toxic, even in small quantities, they also raise environmental and safety concerns. Pharmaceutical companies, for example, must use expensive purification methods to limit residual levels of these elements in pharmaceutical products. Iron, by contrast, is both naturally abundant and far less toxic than heavy metals. Previous work by other researchers has shown that iron nanoparticles - tiny pieces of metallic iron - can be used to activate the hydrogenation reaction. Iron, however, has a wellknown drawback: it oxidises in the presence of oxygen or water. When oxidised, iron nanoparticles stop acting as hydrogenation catalysts. This problem, which occurs with so much as trace quantities of water, has prevented iron nanoparticles from being used in industry.


In research published in the journal Green Chemistry, scientists report that they have found a way to overcome this limitation, making iron an active catalyst in water-ethanol mixtures containing up to 90% water. The key to this new method is to produce the particles directly inside a polymer matrix, composed of amphiphilic polymers based on polystyrene and polyethylene glycol. The polymer acts as a wrapping film that protects the iron surface from rusting in the presence of water, while allowing the reactants to reach the water and react. This innovation enabled the researchers to use iron nanoparticles as a catalyst in a flow system, raising the possibility that iron could be used to replace platinum-series metals for hydrogenation under industrial conditions. “Our research is now focused on achieving a better understanding of how the polymers are protecting the surface of the iron from water, while at the same time allowing the iron to interact with the substrate,” says Audrey Moores, an assistant professor of chemistry at McGill and co-corresponding author of the paper. Co-author of the paper Prof Yasuhiro Uozumi of Riken and the Institute for Molecular Science says, “The approach we have developed through this collaboration could lead to more sustainable industrial processes. This technique provides a system in which the reaction can happen over and over with the same small amount of a catalytic material, and it enables it to take place in almost pure water - the green solvent par excellence.”

Water test kit The WaterTest Kit is used for the quantitative determination of water content in % of mineral and lubrication oils. The simple addition of two reagents to the contaminated oil causes an increase of pressure in the measuring cell. This pressure increase is read off via the digital display as water content in % or ppm. The measurement range can be selected from 0.02-1%, 0-10% and 100-3000 ppm. The time per measurement is approximately 2 min without sample preparation. The product’s plastic housing is lightweight, impact-proof and chemicalresistant. The pressure sensor is easily cleaned and has highly accurate measurement. There is high resolution in the lower measurement range. HYDAC International Contact info and more items like this at

Automated clinical sample concentrator system Promega has launched the Maxwell CSC instrument and integrated reagent kits for blood DNA and DNA FFPE. The solutions have been developed in compliance with the FDA’s Quality System Regulation and are intended as in vitro diagnostic (IVD) medical devices. Complying with these stringent requirements ensures consistent performance between instruments and runs. The technology extracts nucleic acid using novel paramagnetic particles, allowing optimal capture, wash and elution of the target material. Because there are no tubes or pipette tips involved, there are no clogs, drips, splashing or aerosols, reducing any contamination risk. Depending on which specific CSC kits are used (for blood or FFPE tissues), the instrument can purify DNA from up to 16 samples in under 45 min of processing time, providing high-quality nucleic acids appropriate for downstream analysis in amplification-based assays. The system’s Windows 7-based touch-screen interface provides laboratories with the ability to easily track samples, instrument selfcheck reports, kit lot number and expiration dates, and operator usage, and to document parameters and protocols.

Beaming up information with quantum teleportation University of Queensland (UQ) physicists have successfully ‘teleported’ an atom, transmitting it from one location to another inside an electronic chip. This marks the first time quantum teleportation has been achieved in a solid-state system.


he team includes Dr Arkady Fedorov and Dr Matthias Baur, who recently moved to UQ’s ARC Centre of Excellence for Engineered Quantum Systems from ETH Zurich, where the research was conducted. Other members from ETH Zurich include L Steffen, Y Salathe, M Oppliger, P Kurpiers, M Baur, C Lang, G Puebla-Hellmann and Andreas Wallraff. Dr Fedorov described quantum teleportation as “a process by which quantum information can be transmitted from one place to another without sending a physical carrier of information”. In this case, it was used to relay information from one corner of an integrated electronic circuit to the other in a way that is impossible in a classical world. “In this process the information just appears at the destination,” said Dr Fedorov, “almost like teleportation used in the famous science fiction series Star Trek.” Dr Fedorov said the team’s macroscopic quantum system uses a circuit “much like modern computer chips”. The quantum information is stored in quantum bits (qubits) - artificial structures which can be seen with the naked eye. In order to teleport the information one needs three qubits in total, with two being prepared in an entangled state. Entanglement is a special type of correlation shared between a sender and a receiver, said Dr Fedorov, and once it is created, “this ‘impossible’ information transfer becomes in fact possible thanks to laws of quantum mechanics”.

Dr Fedorov said the qubits allowed the researchers “to do teleportation with impressive speed and accuracy above the classical threshold”. While in other experiments teleportation occurs every few seconds, “our system allows us to teleport a quantum state more than 10,000 times per second”. The breakthrough was enabled through a measurement scheme that distinguishes between all four entangled Bell states in a singleshot measurement. The team’s device uses a crossed quantum bus technology that improves scalability in these systems and will lead to larger and more complex systems in the future. Dr Fedorov said the technology is being used in UQ’s Superconducting Quantum Devices Laboratory “to further enhance our knowledge of quantum information processing”. Eventually it will be used to create more powerful devices, he said, such as larger electronic networks and more functional electronic chips. This research indicates that questions relating to the physics of quantum communication can be addressed using electronic circuits at microwave frequencies. In future experiments, quantum entanglement may even be distributed over larger distances directly by microwave photons or using microwave to optical interfaces for quantum communication. Teleportation is expected to find applications in secure communication and in more efficient information processing based on the laws of quantum physics. The research has been published in the journal Nature.

Ultracompact refrigeration circulator Huber Ministats are small cooling circulators which have enough power to thermoregulate photometers, refractometers, viscosimeters, distillation apparatus, reactor vessels and mini plants. Their compact form allows them to be placed in areas where space is at a premium. They can be used to control external applications or objects that can be thermoregulated directly in the bath. The range consists of three models which are available as air- or water-cooled versions. Depending on the model, working temperatures from -45 to +200°C and cooling capacities of 600 W can be achieved. The maximum admissible environmental temperature for continual operation is +40°C. A powerful variable speed pressure/suction pump allows optimum circulation and can be controlled using an optional pressure sensor which protects delicate glassware. All models have Active Cooling Control for cooling power control at the maximum working temperature and an automatic cooling power regulation for energy-saving operation and reduced heat dissipation into the lab. Parts in contact with the thermal fluid are made of stainless steel or polycarbonate, guaranteeing long service life. The product is fitted with the Pilot ONE touch-screen controller, which provides comfortable navigation and advanced control technology. Operation is via a colour 5.7″ TFT touch-screen display with convenient menu prompts and full text menu guidance in 11 languages. Important parameters such as process temperature, jacket temperature, pump pressure and safety equipment are visible at a glance - the temperature processes are graphically displayed and shown in real time. Ease of use is facilitated with USB/LAN connections, which also benefits data recording or remote control. For example, temperature measurement data can be easily stored on a USB stick. The USB connection also allows a connection to a PC or notebook. Combined with the Huber Spy Software, requirements such as remote control or data transmission can be performed easily.

Scorpions and spectrometers to improve cancer surgery By Lauren Davis Scorpions could hold the secret to better cancer treatment, according to researchers from the Queensland Tropical Health Alliance (QTHA). The alliance recently acquired a $1.2 million nuclear magnetic resonance (NMR) spectrometer and facility to investigate the structure of promising molecules, some of which are found in scorpion venom. Professor Norelle Daly’s research into scorpion venom began as a collaboration with Professor David Craik at the University of Queensland (UQ) and Dr Jim Olson at the Fred Hutchinson Cancer Research Center in Seattle. She explained, “The scorpion toxin, chlorotoxin, has been shown to bind to tumour cells. Therefore, labelling the toxin with a dye allows the tumour cells to be visualised.” Such visualisation would help to more clearly distinguish the margin between cancerous and healthy cells during surgery, Professor Daly said. She hopes to find features in the scorpion toxin which “might one day help surgeons more accurately target cancers, including brain tumours”. After applying for an Australian Research Council Future Fellowship to join the QTHA at James Cook University (JCU), she learned that JCU’s Professor Alex Loukas and Dr Jason Mulvenna, who had recently established laboratories with high-end mass spectrometry equipment, were also keen to establish an NMR facility. “As my research requires an NMR, we put in an application for a LIEF grant from the Australian Research Council to partially fund an NMR spectrometer,” Professor Daly said. The researchers were awarded $630,000 to support the high-resolution, high-throughput NMR facility, while the rest of the money was put in by JCU. Dr David Wilson was also funded by JCU to manage the facility. Dr Wilson explained that NMR occurs when the nuclei of certain atoms, placed in magnetic fields, absorb and re-emit electromagnetic radiation. “Some nuclei experience this phenomenon and others do not,” he said, “so we can measure this to try and understand the structure of these molecules, including those in scorpion venom.” The facility’s NMR spectrometers, featuring cryogenically cooled probes, are also being used to study the structures of small proteins and small molecules isolated from creatures such as spiders, cone snails, jellyfish and hookworms, as “the structural information gained from these studies might be useful in the drug design process”, Professor Daly said. She further noted that NMR spectroscopy is “highly suited to studying the [3D] structures of small proteins that are often present in venomous creatures”, as it is one of only two techniques which can reveal a high level of structural detail (the second being X-ray crystallography). Meanwhile, outside the facility the original collaboration continues. Professor Daly and her research colleagues are doing some of the characterisation studies together, while Dr Olson is exploring whether tumour imaging can be used to help surgeons more effectively remove tumours.
