Do people everywhere care less about their cats than their dogs?

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Previous studies have suggested that owners care more about dogs than cats — maybe because dogs are generally considered more affectionate and require more hands-on care. But these studies have used convenience samples and are only based in one country. Scientists surveyed representative samples from Denmark, Austria, and the UK, and found that people generally invest more emotionally and financially in their dogs than their cats, but that the difference is biggest in Denmark and smallest in the UK. This suggests that there is no universal preference for dogs based on their behavior. Do canines get more care? Some studies have suggested pet owners are less emotionally attached to and less willing to finance care for cats than dogs, possibly because of cats’ behavior: cats may be perceived as caring less about humans and needing less care in return. But these studies are often conducted on non-representative samples and don’t consider possible cultural differences in attitudes to pets. A team of scientists led by Dr Peter Sandøe of the University of Copenhagen decided to investigate further. “We and others have found that people are willing to spend much less on their cats […]

Do humans get lazier when robots help with tasks?

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com ‘Social loafing’ is a phenomenon which happens when members of a team start to put less effort in because they know others will cover for them. Scientists investigating whether this happens in teams which combine work by robots and humans found that humans carrying out quality assurance tasks spotted fewer errors when they had been told that robots had already checked a piece, suggesting they relied on the robots and paid less attention to the work. Now that improvements in technology mean that some robots work alongside humans, there is evidence that those humans have learned to see them as team-mates — and teamwork can have negative as well as positive effects on people’s performance. People sometimes relax, letting their colleagues do the work instead. This is called ‘social loafing’, and it’s common where people know their contribution won’t be noticed or they’ve acclimatized to another team member’s high performance. Scientists at the Technical University of Berlin investigated whether humans social loaf when they work with robots. “Teamwork is a mixed blessing,” said Dietlind Helene Cymek, first author of the study in Frontiers in Robotics and AI. “Working together can motivate people […]

Chronic pain may increase dementia risk: Here are five Frontiers articles you won’t want to miss

by Deborah Pirchner, Frontiers science writer Image: Shutterstock.com At Frontiers, we bring some of the world’s best research to a global audience. But with tens of thousands of articles published each year, it’s impossible to cover all of them. Here are just five amazing papers you may have missed. Chronic pain associated with increased dementia risk Alzheimer’s disease and related dementias (ADRD) make up approximately 80% of the more than 47 million cases of dementia worldwide. Looking into the future, cases are expected to increase sharply in the coming decades. A large percentage of the older population is also affected by chronic pain, a leading cause of disability that shares many risk factors with ADRD. These include advanced age, depressive disorders, diabetes, obesity, social isolation, and a low level of education. Now, researchers in France have assessed the impact of chronic pain on the incidence of ADRD. They published their results in Frontiers in Aging Neuroscience. They found that the presence of chronic pain is associated with a higher incidence and risk of developing ADRD when compared with older adults with no chronic pain. The researchers stressed the importance of prevention, diagnosis, and management of chronic pain to limit resulting […]

Caution, ocelot crossing: special wildlife exits on busy roads help protect endangered cat

By Mischa Dijkstra, Frontiers science writer Texas ocelot, Leopardus pardalis albescens. Image credit: Kline Lab, University of Texas Rio Grande Valley Traffic collisions are a major cause of death of endangered Texas ocelots. Researchers have now shown that recently designed wildlife exits, meant to allow ocelots to leave highways surrounded by fences, function as they are designed to do. 10 mammal species apart from ocelots learned to use them correctly. The authors concluded that these exits are a useful conservation measure in Texas, not only for ocelots. The Texas ocelot (Leopardus pardalis albescens) is endangered due to historic hunting, habitat loss, inbreeding, and traffic collisions. Today, only between 50 and 80 ocelots remain in the US, exclusively in Willacy and Cameron counties in southern Texas. These two populations are isolated from the larger one in northwestern Mexico by highways and urban development. “Here we show that a range of species, including middle-sized carnivores such as bobcats and coyotes, successfully use wildlife exits, a new type of mitigation structure specifically designed for the US endangered ocelot,” said first author Zarina Sheikh, a former graduate student at the University of Texas Rio Grande Valley, about their new study in Frontiers in Ecology […]

Cycling in school improves teenagers’ mental health, but wider social factors may impact benefits

by Deborah Pirchner, Frontiers science writer Image: Eric Arce for Outride Physical activity promotes mental well-being and finding activities that people are keen to engage in is key. For teenagers, cycling might be one of them – combining fun, competition, and transportation needs. Researchers in the US have examined if taking part in an in-school cycling program improves middle schoolers’ mental health and found positive effects. While they concluded that cycling programs may be a pathway to improved mental well-being of teenagers, they also noted that the conditions in which students are born and live in determine mental and physical well-being significantly. Physical activity has positive effects on mental health and yet, activity rates are declining. This is particularly worrying because the mental well-being of teenagers continues to deteriorate. In the US, one in six school children is diagnosed with some type of mental disorder. Riding bikes is a promising approach to introduce school-aged children to physical activity. Now, researchers in the US have investigated how adolescents’ psychosocial well-being changed after participating in a school-based cycling program. “Participation in a school cycling education program during the Covid-19 pandemic was associated with improved psychosocial well-being amongst middle schoolers in the US,” […]

Peregrine falcons set off false alarms to make prey easier to catch

by Angharad Brewer Gillham, Frontiers science writer Image: US Fish and Wildlife Service Pacific Southwest Region, public domain Can clever predators manipulate prey into taking bigger risks, making them easier to hunt? Scientists have found that, by carrying out attacks which force Pacific dunlins into exhausting evasive maneuvers, peregrine falcons increase the likelihood of successfully hunting those dunlins later. The prey birds are tired out or forced to forage at more dangerous times. Predators must eat to survive — and to survive, prey must avoid being eaten. One theory, the Wolf-Mangel model, suggests predators could use false attacks to tire prey out or force them to take bigger risks, but this has been hard to show in practice. Now, scientists observing peregrine falcons have found evidence that they deliberately exhaust their prey to improve later hunting success. “Although predators are imagined as clever in novels and movies, like the velociraptors in Jurassic Park, empirical biologists are generally not inclined to give much credence to such ideas,” said Dr Ronald Ydenberg of Simon Fraser University, lead author of the study in Frontiers in Ethology. “I have often been puzzled when watching raptors by aspects of their behavior, such as prominent perching […]

Our sense of smell changes the colors we see, show scientists

By Mischa Dijkstra, Frontiers science writer Crossmodal associations occur when people make unconscious but stereotypical connections between two or more senses. Here, scientists showed that associations between odors and colors can be particularly strong: powerful enough to distort our perception of colors. Our five senses bombard us with environmental input 24/7. One way our brain makes sense of this abundance of information is by combining information from two or more senses, such as between smells and the smoothness of textures, pitch, color, and musical dimensions. This sensory integration also causes us to associate higher temperatures with warmer colors, lower sound pitches with less elevated positions, and colors with the flavor of particular foods – for example, the taste of oranges with the color of the same name. Now, a study in Frontiers in Psychology has shown experimentally that such unconscious ‘crossmodal’ associations with our sense of smell can affect our perception of colors. “Here we show that the presence of different odors influences how humans perceive color,” said lead author Dr Ryan Ward, a senior lecturer at Liverpool John Moores University in Liverpool, UK. Sensory-deprived room Ward and colleagues tested for the existence and strength of odor-color associations in 24 […]

Can masculine marketing convince more men to eat vegan?

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Eating more plant-based dishes is good for your health and good for the planet – but the perception that these dishes are for women and not for men may be stopping some men from choosing plant-based meals. Scientists found that you can present vegan dishes with a masculine framing, altering the perception that these dishes are for women, but changing the perception doesn’t change people’s preferences. Eating more plant-based meals is better for our health and better for the planet. But cultural preferences are significant barriers to reducing meat consumption – especially for men, who are underrepresented among vegans and vegetarians. Studies have found that eating meat is associated with masculinity, and that gender stereotypes label plant-based diets as suitable for women but not men. So is it possible to change the perception of plant-based food with marketing, and convince men to eat more of it? “Men might be less inclined to consume vegan food due to the need to perform gender,” said Alma Scholz, lead author of a new study published in Frontiers in Communication. “However, with vegan food being framed in a masculine way, men might feel less resistance and […]

Mouthwash for dogs: water additive with pomegranate helps to keep canine teeth healthy

By Mischa Dijkstra, Frontiers science writer Veterinarian researchers performed a blinded randomized controlled trial to show that a commercially available water additive with pomegranate extract is effective in limiting the reformation of plaque and tartar on the teeth of dogs after a professional dental cleaning. This could help to prevent periodontal disease in the long term. Periodontal disease is one of the most common canine diseases, affecting at least 80% of dogs aged three and over. Periodontal disease begins as gingivitis, where gums become red and inflamed, and may bleed. Untreated, the disease can progress to periodontitis, where the alveolar bone is progressively damaged so that teeth may loosen or fall out. In turn, periodontitis is a risk factor for other diseases like cardiovascular and lung disease. A major cause of periodontal disease is poor oral hygiene, which can lead to the build-up of plaque and tartar. For this reason, veterinarians counsel owners to brush their dogs’ teeth regularly. Unfortunately, compliance with this advice is low, because it’s onerous or because some dogs won’t cooperate. “Here we show that an additive to drinking water, based on pomegranate extract, can reduce the accumulation of plaque and tartar in dogs,” said Dr […]

Swimming lessons often discourage kids from just having fun in the pool

By Mischa Dijkstra, Frontiers science writer Researchers rated the teaching style of swimming teachers in the Netherlands, focusing on the degree to which the need for autonomy, competence, and relatedness of children were thwarted or supported on the whole. They concluded that there is an opportunity to improve swimming teaching styles, especially by focusing more on the need for autonomy in children. It is expected that this will improve the enjoyment of children and their willingness to continue once they have become competent swimmers. Learning to swim is not just potentially life-saving: it also provides a full-body workout that promotes cardiovascular and lung health. While in high-income countries most children learn to swim, few join a swimming club afterwards. Here, authors from the Netherlands showed that the way that swimming lessons are taught in the Netherlands can be improved. This could stimulate more children to keep up the activity. The results are published in Frontiers in Sports and Active Living. Lead author Carola Minkels, a doctoral student at the Department of Human Movement Sciences of the Free University Amsterdam, said: “Here we show that swimming lessons in the Netherlands poorly support the intrinsic motivation of children: their need for autonomy […]

Why ecological restoration without Indigenous leadership won’t last

by Dr Jennifer Grenz, University of British Columbia Dr Jennifer Grenz. Image: UBC Dr Jennifer Grenz is the principal investigator at The Indigenous Ecology Lab at the University of British Columbia. There, researchers apply an Indigenous, relational worldview to ecological restoration. Grenz has nearly two decades of experience providing consulting services and on-the-ground management of invasive species for all levels of government as well as working with Indigenous communities on creating food security plans and land healing initiatives consistent with community values and needs. Her current research focuses on applying an Indigenous worldview to invasive plant species on landscapes in British Columbia, challenging us to think differently about our role in ecosystems management as we face a rapidly changing climate. Together with Dr Chelsey Armstrong of the Historical Ecological Research Lab at Simon Fraser University, Grenz is co-author of a recently published Frontiers in Sustainable Food Systems article. In it, they introduce the concept of ‘pop-up restoration’, meaning fragmented, disconnected, privileged restoration that perpetuates colonial notions of naturalness. In this latest Frontiers guest editorial, she wrote about their latest work. Imagine you’re sitting in your living room on a quiet evening with your family reading a book, when suddenly, complete […]

Holidays back to the home country could help bilingual children hold on to their family’s original language

by Angharad Brewer Gillham, Frontiers science writer Image/Shutterstock.com Holding on to a heritage language which isn’t widely spoken in the country of residence is difficult. Scientists find that using the heritage language at home, in daily life, is important to retaining it, but that some of the language skills which are most vulnerable — like vocabulary — are improved by visits to the country of origin. It’s hard to keep a language in the family. Many people who migrate to different countries find that their language of origin has become a heritage language, passed on to future generations with varying degrees of success. These languages come under pressure from the dominant language in a country as well as the lack of opportunities to practice and fluent speakers to practice with. So how do kids use or retain heritage languages? And can visits to their parents’ countries of origin help them increase their fluency? “The role of parental language use in the country of residence is well-established,” said Prof Vicky Chondrogianni of the University of Edinburgh and Dr Evangelia Daskalaki of the University of Alberta, authors of the study in Frontiers in Language Science. “Here we show how the opportunities to […]

Shading the Great Barrier Reef from the sun might slow bleaching-induced coral decline

By Deborah Pirchner, Frontiers science writer Image: Shutterstock As ocean temperatures rise, corals can lose their color due to heat stress. Bleaching does not kill corals immediately, but they become more vulnerable to disease and starvation. Shading reefs by covering them with cloth or fog, can protect them from excessive heat. Now, researchers have tested the shading response of two coral species and found that four hours of shade during the hottest time of the day can significantly slow bleaching. This knowledge can help with solar radiation management in marine ecosystems, including the Great Barrier Reef. Over the past two decades, coral reefs have declined at unprecedented rates. This is in part because of extreme weather events, which cause wide-spread coral bleaching, a process during which corals lose their color because of stressors, including changes in water temperature, light, or nutrient availability. One of the worst mass bleaching events occurred in 2016 and 2017 on the Great Barrier Reef, causing bleaching on 91% of the system’s reefs. As frequency and severity of mass bleaching events are expected to increase in the future, researchers are looking for ways to protect corals from excessive radiation and temperatures. As part of the Cooling […]
