Cracking the case for non-glass wine bottles

Peer-Reviewed Publication

UNIVERSITY OF SOUTH AUSTRALIA

Would you be happy to pour your friends a glass of wine from a cask or sip your favourite red from an aluminium can?

Traditional glass bottles have long been the preferred choice of packaging among wine lovers due to the belief that wine looks and tastes better in glass. While glass bottles have been the wine industry’s go-to for centuries, they are not the most carbon-friendly option available.

Researchers from the University of South Australia’s Ehrenberg-Bass Institute for Marketing Science and the University of Adelaide’s Business School have explored people’s wine packaging choices, and how attributes such as price, brand, and messaging can influence them.

Lead researcher Jakob Mesidis says previous wine packaging research has largely focused on wine label and closure (cork or screw-top) preferences, but little attention has been paid to the format of the packaging.

“We knew that consumers weren’t buying alternatively packaged wine at the same rate they were buying it bottled, so we wanted to know what we should change to motivate them to choose more sustainable options,” he says.

Conventional glass wine bottles are the wine industry’s largest source of carbon emissions, with the manufacture of a single bottle generating 1.25kg of carbon dioxide. In total, the production and transport of glass wine bottles make up more than two thirds of the wine industry’s total carbon output.

Australia’s main alternative wine packaging formats are the ‘bag-in-box’ (i.e., cask wine) and aluminium cans, although new formats, such as flat plastic wine bottles, are gradually entering the market each day.

These alternative formats are up to 51% more carbon efficient than glass, but Mesidis says Australian consumers are resistant when it comes to these more environmentally friendly options.

“There are some underlying prejudices in relation to alternative wine packages as they are seen as the cheaper, low-quality option when compared to glass bottles, which come with a sense of heritage and luxury,” he says.

“Canned wine has seen a rise in popularity but is still a small portion of the market. Flat bottles have only recently been introduced to Australia but have grown in popularity overseas.”

So, what can the wine industry do to bring consumers on board?

In a survey of 1200 Australians, the Ehrenberg-Bass Institute found that cask wine and flat plastic wine bottles were the most preferred formats after traditional glass bottles. Cans were the least preferred, as they were closely tied to specific occasions, such as drinking outdoors.

Results also found that package format was the biggest influence on people’s choices. Price came second, while the importance of brand and eco-messaging varied depending on the respondent’s age and how many eco-friendly behaviours they claimed to engage in.

Alternative wine formats were also typically bought more by younger people. Consumers were found to be more likely to choose alternative wine packaging when it is priced at a mid-to-low price range and if it comes from a well-known, prestigious brand.

“If a smaller, less-known winery’s mission is to grow its brand as much as possible, relying solely on alternatively packaged wines is not the way to go. Most Australians—for the time being—are still going to reach for a glass bottle when they’re at the shops,” Mesidis says.

“Larger, more prestigious brands are likely to see more success with alternatively packaged wine. Ultimately, this research provides wine marketers with a foundation for their low-carbon wine packaging strategies, rather than blindly navigating this relatively new field.

“Research in this space is still young and there is exciting work to be done to better understand this burgeoning part of the wine industry.”

Scientists have found naturally occurring pathogenic fungi infecting the Eucalyptus snout beetle in Eucalyptus forest plantations, and characterised them to develop a bio-pesticide for controlling the beetle.

Gonipterus platensis, or the Eucalyptus snout beetle, has a heavy impact on Eucalyptus forest plantations worldwide, and it is mostly controlled using the micro wasp Anaphes spp., although control rates rarely become financially viable. This led a team of scientists to look for naturally occurring pathogenic fungi to tackle the Eucalyptus snout beetle problem.

Worldwide, the Eucalyptus forest covers more than 20 million hectares. In the Iberian Peninsula, the Eucalyptus snout beetle could cause defoliation levels of 100% and produce wood volume losses of up to 86%. Although Eucalyptus wood is important for paper pulp production, the biological control of the Eucalyptus snout beetle is far from total, and on some occasions chemical control is needed, too. 

The identification of fungi pathogenic to the Eucalyptus snout beetle is not new. What is remarkable in this new research is that the scientists collected the fungi from naturally infected beetles in the current distribution area in Colombia, so the fungi will be well-adapted to the environmental conditions, which is promising for controlling the beetle in forest plantations.

To ensure that the recovered fungi are suitable for developing a bio-pesticide, the scientists characterized them in terms of insecticidal activity, UV-B radiation tolerance and other parameters. This characterisation ensures that the fungi are suitable for mass production of a bio-pesticide and, when used in forest plantations, are resistant to the environmental conditions. Beauveria pseudobassiana and Metarhizium brunneum were the most virulent fungi. B. pseudobassiana was the most adapted for producing a bio-pesticide and tolerant to the environmental conditions.

The fungi could be used to develop a bio-pesticide, after trials in Eucalyptus forests. Later, the fungi could also be used in other countries where the insect is causing severe damage.

This work was supported by the Ministry of Agriculture and Rural Development, Colombia, through Corporación Colombiana de Investigación Agropecuaria – AGROSAVIA, as part of the project “Strategies for planning and management of forest plantations and agroecosystems in Colombia”. The scientists are looking for new funding to run tests in field conditions.

In the ongoing biodiversity crisis, large terrestrial animals are more threatened by extinction than any other group of organisms. The African continent holds an impressively intact large-mammal community, but there is still a lot we do not know about how these species evolved, became diverse and adapted to the changing climate and habitats. Many of these questions can be addressed by investigating the genomes and genetic variation across species.

New research, published in Nature Communications, uses genomics to answer these evolutionary questions that have been debated amongst scientists for decades: 1) how and when did bushpigs cross the Mozambique Channel and arrive at the island of Madagascar, 2) is there one or two species of bushpigs?

- “This study is a result of a large international collaboration with researchers from Africa and Europe. We sequenced 67 complete bushpig genomes and by using a range of different genetic analyses, we were able to address these long-standing puzzles in African evolution and biogeography”, explains one of the senior authors of the study, Associate Professor at the Department of Biology, Rasmus Heller.

 

Were pigs ferried across the channel during the Medieval era?

The island of Madagascar separated from the African mainland around 160 million years ago, resulting in a largely unique flora and fauna. Remarkably, the bushpig is the only large, wild terrestrial mammal species that has somehow historically crossed the 400-kilometer-wide Mozambique Channel and made it from mainland Africa to the island of Madagascar.

- “Our study establishes that the bushpig was introduced to Madagascar ≈1,000-5,000 years ago from South/South-East Africa”, Rasmus states. Their arrival therefore coincides with the arrival of humans to Madagascar from a region around southern Africa. Rasmus continues: “The likely explanation for this is that people transported these bushpigs across the channel. These results contradict previously published studies which dated the arrival of bushpigs ≈480,000 years ago, well before humans were present on the island”. It has been suggested that some endemic Madagascar species might have arrived by rafting as passengers on floats of vegetation.

- “Intriguingly, our results raise a host of new questions: was the bushpig actually brought to Madagascar as a somewhat domesticated species? There is no archaeological or other evidence of bushpig domestication ever occurring, despite them being an important source of protein for many rural communities. And who was it that transported these animals to Madagascar? Was it Bantu-speakers, Austronesian-speakers or both? These questions and others still remain to be explored,” explains Renzo F. Balboa, postdoc at the Department of Biology and one of the leading authors of the study.

 

Does two actually equal one?

African bushpigs, which primarily are found in East/Southern Africa, and red river hogs, which are found in West/Central Africa, were considered the same species in the past, but were subsequently redefined as two species around the 1990s, largely due to their quite distinctive looks.

The red river hogs are, as the name implies red, and have long, tufted ears reminiscent of a comical Star Wars character, while eastern and southern African bushpigs are greyish and look more like our own wild boar, although with a beautiful white mane thrown in for good measure.

Biologists have been arguing for decades about whether these two forms are actually one or two different species - a debate that is characteristic of similar scientific uncertainty surrounding many other African mammals.

- “In this study, we were able to conclude that red river hogs and bushpigs have had lots of gene flow, which means they are not only able to potentially interbreed, but they have in fact done so extensively when they have met in central Africa. Furthermore, the branching of the two types in the Tree of Life is not all that old, only a few hundred thousand years, which is not long in the evolutionary scheme of things. Hence, we now know that although there are two quite different-looking lineages of bushpigs, their biological separation is incomplete, depending on how you define species”, explains Laura D. Bertola, postdoc at the Department of Biology and the other leading author of the study.

Laura continues: “Genomic data can give us insights into patterns of biodiversity on a much higher resolution than previously possible. For example, we can infer detailed population structure, but also underlying processes like gene flow and selection. Gaining improved insights into patterns of biodiversity and the underlying processes that drive them, will be crucial for effective conservation measures”.

Africa is a unique continent regarding the diversity of the megafauna which is still around. Studying the evolutionary history of these species can give us important insights into African biodiversity, which is highly relevant at a time where biodiversity is being lost at an alarming pace. The new findings contribute to our understanding of prehistoric relations between Africa’s humans and wildlife, but also the very fundamentals about how much biodiversity there is on this amazing continent.

- “This study is a great example of how involving local researchers and wildlife management authorities can lead to more robust and inclusive scientific research”, co-author Vincent Muwanika, Associate Professor of Conservation Biology, at Makerere University, Uganda, concludes.

 

The study is part of the African Wildlife Genomics research framework led by research groups at the Department of Biology at the University of Copenhagen. This research framework is an associated partner project of the African BioGenome Project (https://africanbiogenome.org/) - an African-led initiative to use genomics in the service of conservation and capacity building in Africa.

Putting your toddler in front of the TV? You might hurt their ability to process the world around them, new data suggests

Peer-Reviewed Publication

DREXEL UNIVERSITY

Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviors, such as being disengaged and disinterested in activities, seeking more intense stimulation in an environment, or being overwhelmed by sensations like loud sounds or bright lights, according to data from researchers at Drexel’s College of Medicine published today in the journal JAMA Pediatrics.

According to the researchers, children exposed to greater TV viewing by their second birthday were more likely to develop atypical sensory processing behaviors, such as “sensation seeking” and “sensation avoiding,” as well as “low registration” — being less sensitive or slower to respond to stimuli, such as their name being called, by 33 months old.

Sensory processing skills reflect the body’s ability to respond efficiently and appropriately to information and stimuli received by its sensory systems, such as what the toddler hears, sees, touches, and tastes.

The team pulled 2011-2014 data on television or DVD-watching by babies and toddlers at 12- 18- and 24-months from the National Children’s Study of 1,471 children (50% male) nationwide.

Sensory processing outcomes were assessed at 33 months using the Infant/Toddler Sensory Profile (ITSP), a questionnaire completed by parents/caregivers, designed to give insights on how children process what they see, hear and smell, etc.

ITSP subscales examine children’s patterns of low registration, sensation seeking, such as excessively touching or smelling objects; sensory sensitivity, such as being overly upset or irritated by lights and noise; and sensation avoiding — actively trying to control their environment to avoid things like having their teeth brushed. Children score in “typical,” “high” or “low” groups based on how often they display various sensory-related behaviors. Scores were considered “typical” if they were within one standard deviation from the average of the ITSP norm.

Measurements of screen exposure at 12-months were based on caregiver responses to the question: “Does your child watch TV and/or DVDs? (yes/no),” and at 18- and 24- months based on the question: “Over the past 30 days, on average, how many hours per day did your child watch TV and/or DVDs?”

The findings suggest:

• At 12 months, any screen exposure compared to no screen viewing was associated with a 105% greater likelihood of exhibiting “high” sensory behaviors instead of “typical” sensory behaviors related to low registration at 33 months 
• At 18 months, each additional hour of daily screen time was associated with 23% increased odds of exhibiting “high” sensory behaviors related to later sensation avoiding and low registration.
• At 24 months, each additional hour of daily screen time was associated with a 20% increased odds of “high” sensation seeking, sensory sensitivity, and sensation avoiding at 33 months.

The researchers adjusted for age, whether the child was born prematurely, caregiver education, race/ethnicity and other factors, such as how often the child engages in play or walks with the caregiver.

The findings add to a growing list of concerning health and developmental outcomes linked to screen time in infants and toddlers, including language delay, autism spectrum disorder, behavioral issues, sleep struggles, attention problems and problem-solving delays.

“This association could have important implications for attention deficit hyperactivity disorder and autism, as atypical sensory processing is much more prevalent in these populations,” said lead author Karen Heffler, MD, an associate professor of Psychiatry in Drexel’s College of Medicine. “Repetitive behavior, such as that seen in autism spectrum disorder, is highly correlated with atypical sensory processing. Future work may determine whether early life screen time could fuel the sensory brain hyperconnectivity seen in autism spectrum disorders, such as heightened brain responses to sensory stimulation.”

Atypical sensory processing in kids with autism spectrum disorder (ASD) and ADHD manifests in a range of detrimental behaviors. In children with ASD, greater sensation seeking or sensation avoiding, heightened sensory sensitivity and low registration have been associated with irritability, hyperactivity, eating and sleeping struggles, as well as social problems. In kids with ADHD, atypical sensory processing is linked to trouble with executive function, anxiety and lower quality of life.

“Considering this link between high screen time and a growing list of developmental and behavioral problems, it may be beneficial for toddlers exhibiting these symptoms to undergo a period of screen time reduction, along with sensory processing practices delivered by occupational therapists,” said Heffler.

The American Academy of Pediatrics (AAP) discourages screen time for babies under 18-24 months. Live video chat is considered by the AAP to be okay, as there may be benefit from the interaction that takes place. AAP recommends time limitations on digital media use for children 2 to 5 years to typically no more than 1 hour per day.

“Parent training and education are key to minimizing, or hopefully even avoiding, screen time in children younger than two years,” said senior author David Bennett, PhD, a professor of Psychiatry in Drexel’s College of Medicine.”

Despite the evidence, many toddlers view screens more often. As of 2014, children age 2 and under in the United States averaged 3 hours, 3 minutes a day of screen time, up from 1 hour, 19 minutes a day in 1997, according to a 2019 research letter in JAMA Pediatrics. Some parents cite exhaustion and inability for affordable alternatives as reasons for the screen time, according to a July 2015 study in the Journal of Nutrition and Behavior.

Although the current paper looked strictly at television or DVD watching, and not media viewed on smartphones or tablets, it does provide some of the earliest data linking early-life digital media exposure with later atypical sensory processing across multiple behaviors. The authors said future research is needed to better understand the mechanisms that drive the association between early-life screen time and atypical sensory processing.

In addition to Heffler and Bennett, authors on this paper include Binod Acharya, who completed the work while at Drexel’s Dornsife School of Public Health’s Urban Health Collaborative, and Keshab Subedi from Christiana Care Health Systems.

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study published in Current Biology. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development.

In wild populations, infant survival is crucial for determining individual fitness and for maintaining viable populations in changing environments. For primates, agricultural areas adjacent to tropical forest habitat can be a mixed blessing: While crop plantations can provide easy access to food, they also come with increased exposure to various hazards, which is likely contributing to reduced infant survival in several wild primate species.

Exposure to palm plantations increases infant mortality

In a long-term collaboration between Universiti Sains Malaysia (USM), the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), and the Max Planck Institute for Evolutionary Anthropology (MPI EVA), researchers set out to investigate potential links between frequent visits to oil palm plantations and the particularly high infant mortality they observed among wild southern pig-tailed macaques in Peninsular Malaysia. In a habituated study population in this region, 57% of all infants born between 2014 and 2023 died before the age of one – a rate that far exceeds mortality rates reported in other wild primate populations.

For almost ten years, the researchers followed two groups of macaques living in a mosaic of rainforest and oil palm plantations. They found that prolonged exposure to oil palm plantations during infancy tripled the likelihood of infant mortality. This key finding could be explained by increased encounters with predators and humans, and potential exposure to harmful chemicals such as pesticides in this environment.

“Some of these risks are relatively clear: infant macaques are more likely to fall prey to feral dogs that roam in the plantations in packs or to be captured by humans and sold illegally as pets,” explains Dr Nadine Ruppert from USM, who established and leads the field site. “But the potential long-term effects of the pesticides used to manage the monocultures on mammalian wildlife are much less obvious and very poorly understood.”

Pesticides may affect foetal development

The study also found increased infant mortality rates when mothers gave birth for the first time or when there was a long interval between two consecutives births, which contradicts studies that report increased mortality when the interbirth interval is shorter. The accumulation or uptake of pesticides in the mother’s body may play a key role: “The literature suggests that certain harmful substances used in agriculture can cross the placental barrier and be passed on to the unborn offspring. We also know that certain fat-soluble molecules can be passed on through breastmilk,” says lead author Dr Anna Holzner (iDiv, MPI EVA, UL and USM). “Accordingly, the longer the chemicals accumulate in the mother’s body, the more they could influence foetal development during pregnancy and also during lactation.”

The study highlights the urgent need to address anthropogenic threats to animals in agricultural landscapes. “We know that the use of pesticides in agriculture has led to drastic declines in insect populations, so chemical analysis is essential to understand the effects of pesticides on mammalian wildlife,” says Professor Dr Anja Widdig (UL, MPI EVA and iDiv), senior author and leading PI in this iDiv Flexpool project. “Our findings underscore the critical need to implement environmentally friendly cultivation practices that minimise the risks to wildlife populations and also to people living near plantations.”

Exploring dimensions of justice in climate science

Peer-Reviewed Publication

INTERNATIONAL INSTITUTE FOR APPLIED SYSTEMS ANALYSIS

How can climate policy be made more just and fair? IIASA researchers have synthesized different dimensions of justice into a framework that can be used by climate scientists and policymakers, explaining how previous research has neglected many potential justice positions and how these can be implemented in policy contexts.

Dealing with climate change is not just about the environment – it is also about justice and fairness. This includes how we transition to cleaner ways of living, the different impacts on various groups of people, and who is responsible for what. Paying more attention to fairness and justice when making decisions will help policymakers to devise better climate policies that people can agree on.

Currently, people however don't always understand or talk about these concepts in the same way. While experts may think about justice and fairness when they plan ways to, for example, reduce carbon emissions, they often don't explain it clearly, instead using different words and measures, which can confuse both researchers and the public. This confusion makes it harder to share and understand the results.

In their new study published in Nature Climate Change, IIASA researchers propose a conceptual framework rooted in philosophical theory to address this gap in possibly the first systematic attempt to describe these different aspects or dimensions of justice for the climate domain in an interdisciplinary context. Their innovative framework synthesizes distributional, procedural, corrective, recognitional, and transitional justice that can be used by scientists and policymakers.

The framework aims to enhance interdisciplinary understanding of climate justice to prevent its mischaracterization and its misuse to justify delayed climate action. Recognizing that justice can either support or hinder decarbonization efforts, the researchers note that more research on justice-related issues is essential for the next cycle of the Intergovernmental Panel on Climate Change (IPCC).

“This framework aims to achieve three goals: improve clarity by using terminology from justice scholarship; promote awareness and consistency in examining justice concerns as part of a coherent whole; and enhance comparability across scenarios and modeling contexts, to facilitate discussions on these issues,” explains IIASA researcher Caroline Zimm, one of the study lead authors.

To implement this framework effectively, the authors propose the creation of a Justice Model Intercomparison Project (JUSTMIP) focused on mitigation scenarios.

“JUSTMIP would provide reporting templates for in-depth exploration of various research aspects, sectors, and model comparisons within the context of scenarios used by the next IPCC Assessment Report. This will raise awareness about the possibilities and limitations regarding justice considerations in these scenarios and enhance transparency,” notes IIASA Energy, Climate, and Environment Program Director, Keywan Riahi.

“It is important to note that our framework does not aim to evaluate what is just or unjust but rather provides a structured platform for identifying and discussing justice considerations. By bringing clarity and consistency to the discourse surrounding climate justice, this framework will empower both researchers and policymakers to navigate the intricate justice landscape and ensure that justice is a fundamental aspect of climate policy decisions,” concludes co-lead author Kian Mintz-Woo, a guest researcher at IIASA who is also associated with the Department of Philosophy and the Environmental Research Institute at University College Cork in Ireland.

This pioneering work is a significant step toward a more holistic and multidimensional understanding of justice in the context of climate change, offering a valuable tool to advance climate policy and research worldwide.

The spectacular explosion of the mine at Hawthorn Ridge – a fortified German front-line position in the First World War – marked the beginning of the Battle of the Somme, and remains one of the best-known pieces of film from the whole conflict.

More than 60ft below the surface, British miners had dug a gallery for more than 900 metres from their lines and packed it with 40,000 lbs of explosives. It was one of 19 mines placed beneath German front positions that were detonated on 1st July, 1916 to mark the start of the offensive.

But the detonation of the mine at Hawthorn Ridge, famously captured by film director Geoffrey Malins, took place 10 minutes before the whistles blew at 7.30am. The early detonation, later described as a ‘colossal blunder’, alerted the Germans the infantry attack was imminent and gave them enough time to take up defensive positions in the newly-formed crater, leading to heavy losses among the attacking British troops.

Now, findings from the first ever multi-disciplinary scientific investigation of the 107-year-old crater have been published in the Journal of Conflict Archaeology. The team of researchers, scientists and historians, led by Keele University, used a range of cutting–edge technology, including drones with imaging cameras, to examine the area like never before.

Researchers discovered and excavated two sections of trenches, known as fire bays, that were used to consolidate newly-formed craters, highlighting how the Germans successfully incorporated the crater rim into their front line after the blast. They also recovered probable communication wire and distinctive German barbed wire, and found evidence of a previously unknown shallow tunnel, believed to have been dug out from the crater by German forces to provide an advanced position in No Man’s Land. They say their findings reveal new details on the history of the crater, its capture by the Germans and how they successfully incorporated it into their front line after the blast.

Dr Jamie Pringle, a forensic geoscientist at Keele University, said: “The explosion of the mine was the very first action of the Battle of the Somme, intended to give Allied forces the upper hand. We found physical evidence for the first time of how German soldiers had consolidated part of the crater left behind after the explosion, and actually used it to their advantage as a new defensive position.”

The group were given exclusive access to the site in France after the Hawthorn Ridge Crater Association took on a 99-year lease from the local authority in 2018 to protect it for future generations. The association was set up as a Franco-British organisation dedicated to the preservation and protection of the site, and carried out extensive clearance works that provided the first opportunity for detailed study.

A second mine was blown by British forces on November 13th, causing a new crater to be formed. This explosion was much more effective, aiding the 51st Highland Division to capture the ridge and nearby village of Beaumont Hamel, which had been a prominent feature of the German frontline position.

The researchers were able to pinpoint the epicentres of the two separate mine detonation locations, and identified 27 post-explosion impact shell homes, fired from British lines as they tried to dislodge the Germans. They also found an unexploded British shrapnel artillery shell with its time-fuse still intact, representative of the large number that failed to explode on the Somme, and an empty ammunition box for a Vickers Machine Gun, reflecting the period of British occupation of the site.

Dr Kris Wisniewski, a lecturer in Forensic Science at Keele University, said: “The land had been in private ownership for almost 100 years, so this scientific study, the first to be carried out on this historically important crater, was both exciting and significant. Using a range of scientific methods, we were able to map out the epicentres of both blasts and the boundaries of the subsequent craters caused by the first and second explosions, as well as post-blast defensive positions and Allied shell impact craters.

“Using drones with imaging cameras, we were able to image remotely a probable sap or shallow tunnel to the northwest of the crater, showing the German mastery of No Man’s Land after the initial detonation.”

Professor Peter Doyle, a military historian at Goldsmiths, University of London, who was part of the team, said: “The Germans had quickly mastered the art of capturing craters and used this to their advantage. Though they lost many men in the initial blast, the crater became a part of the German frontline, meaning that the chance to break through the line here was lost.

“Our study has provided new evidence of the strongpoint the Germans built from the captured crater in the middle of No Man’s Land that doomed the British attack to failure. This reinforces the idea that blowing the mine ten minutes early, to give the earth time to settle, was a very bad idea. It was only with concerted effort four months later, and a new mine, that Hawthorn Redoubt was captured by the Highlanders.”

The research team included representatives from Keele University, London South Bank University, Staffordshire University, Atlantic Technological University, Goldsmiths, University of London, Stoke-on-Trent Archaeology Service and Cotswold Archaeology.
