The research team asked one group of participants to follow healthy eating accounts and another to follow interior design accounts After just two weeks, participants following healthy eating accounts ate more fruit and vegetables and less junk food Even minor tweaks to social media accounts could result in substantial diet improvements in young adults. Researchers from Aston University have found that people following healthy eating accounts on social media for as little as two weeks ate more fruit and vegetables and less junk food. Previous research has shown that positive social norms about fruit and vegetables increases individuals’ consumption. The research team sought to investigate whether positive representation of healthier food on social media would have the same effect. The research was led by Dr Lily Hawkins, whose PhD study it was, supervised by Dr Jason Thomas and Professor Claire Farrow in the School of Psychology. The researchers recruited 52 volunteers, all social media users, with a mean age of 22, and split them into two groups. Volunteers in the first group, known as the intervention group, were asked to follow healthy eating Instagram accounts in addition to their usual accounts. Volunteers in the second group, known as the control group, were asked to follow interior design accounts. The experiment lasted two weeks, and the volunteers recorded what they ate and drank during the time period. Overall, participants following the healthy eating accounts ate an extra 1.4 portions of fruit and vegetables per day and 0.8 fewer energy dense items, such as high-calorie snacks and sugar-sweetened drinks, per day. This is a substantial improvement compared to previous educational and social media-based interventions attempting to improve diets. Dr Thomas and the team believe affiliation is a key component of the change in eating behaviour. For example, the effect was more pronounced amongst participants who felt affiliated with other Instagram users. The 2018 NHS Health Survey for England study showed that only 28% of the UK population consumed the recommended five portions of fruit and vegetables per day. Low consumption of such food is linked to heart disease, cancer and stroke, so identifying ways to encourage higher consumption is vital. Exposing people to positive social norms, using posters in canteens encouraging vegetable consumption, or in bars to discourage dangerous levels of drinking, have been shown to work. Social media is so prevalent now that the researchers believe it could be an ideal way to spread positive social norms around high fruit and vegetable consumption, particularly amongst younger people. Dr Thomas said: “This is only a pilot intervention study at the moment, but it’s quite an exciting suite of findings, as it suggests that even some minor tweaks to our social media accounts might lead to substantial improvements in diet, at zero cost! Our future work will examine whether such interventions actually do change our perceptions of what others are consuming, and also, whether these interventions produce effects that are sustained over time.” Dr Hawkins, who is now at the University of Exeter, said: “Our previous research has demonstrated that social norms on social media may nudge food consumption, but this pilot demonstrates that this translates to the real world. Of course, we would like to now understand whether this can be replicated in a larger, community sample.” Digital Health DOI: 10.1177/20552076241241262

Exploring the Link Between Student Engagement and Deeper Learning
When students are engaged in their learning, they are more likely to dive deeper into the material. This is because they are actively participating in the process, asking questions, and seeking out answers. This is a concept that was recently explored by Amanda Jansen, a University of Delaware professor in the College of Education and Human Development. With attention to teachers’ first-person narratives and reflections, her study offers educators a model for understanding student engagement so that they can better facilitate deeper learning in their classrooms. Funded by the National Science Foundation (NSF), it was found that the majority of the teachers in Jansen’s study understood the primary function of student engagement to be deeper learning about a mathematics concept rather than classroom performance. These teachers talked more about engagement in terms of cognitive, affective and social processes, and they often spoke about more than one dimension. Jansen also emphasizes that how educators ask students to be engaged often reveals helpful information about educators’ instructional practices and their own assumptions. It can also send a message to students about their role in the learning process. These more engaged students are more likely to analyze and evaluate information, rather than just passively accepting it. This higher level of thinking leads to a deeper understanding of the material and allows students to apply their knowledge in real-world situations.

NASA selects University of Delaware’s CubeSat spacecraft for upcoming mission
It’s safe to say that not many students expect to lead a NASA-supported mission during their undergraduate studies. But at least a dozen from the University of Delaware will have done that by the time they collect their diplomas in the next few years. All are part of a team creating Delaware’s first orbital spacecraft, which was selected by NASA for launch in 2026 as part of its CubeSat Launch Initiative. The NASA program, which started in 2011, aims to give students an opportunity to be part of real missions and gain extraordinary experience in what it takes to do space research. CubeSats are small, modular, inexpensive satellites that carry experiments for science investigations and/or technology demonstrations. About 160 CubeSats have been launched in the NASA program over the years, many deployed from the International Space Station (ISS). Delaware’s mission — the Delaware Atmospheric Plasma Probe Experiment (DAPPEr) — will launch its CubeSat spacecraft from the ISS and orbit independently through Earth’s upper atmosphere. The CubeSat will be about the size of a loaf of bread, according to the team’s faculty mentor, Bennett Maruca, associate professor of physics and astronomy. It will gather data about the density and temperature of electrons in Earth’s upper atmosphere, recording changes observed at different latitudes and times of day. This data will inform future research on how the sun affects conditions there. Understanding the sun’s interaction with the Earth’s atmosphere is critical to development of satellite communications networks, global positioning systems (GPS) and national security. But the real objective is educational, Maruca said. The students are the “deliverables.” They’ll emerge from this work with an insider’s view of what it’s like to develop and work on a NASA mission.

New research shines a light on how expert mapmakers at Ordnance Survey see the world differently
OS Remote Sensing Services survey team updating OS MasterMap using the latest aerial imagery (Image credit: OS) Aston University psychologists worked with Ordnance Survey to assess how surveyors use 3D aerial images when making maps Humans naturally assume light comes from above, but experienced surveyors can interpret visual cues to assess topography regardless of the light direction It is the first time it has been shown that experience can radically alter natural human assumptions about lighting and could improve surveyor training. Researchers at Aston University have found differences between experienced Ordnance Survey (OS) mapmakers and novices in the way that they interpret aerial images for mapmaking, which could lead to improved training processes for new recruits. OS is well known for its travel and walking maps, but is also responsible for maintaining Great Britain’s national geographic database. Every time a building is demolished or developed, or a new road and path built, the map must be updated. Aerial photographs are taken of the area that has changed, either from a plane or using drones, and expert mapmakers, known as remote sensing surveyors, will examine the images to identify change and accurately redraw the map of the area. Image pairs are presented stereoscopically, one to each eye, allowing the remote sensing surveyors to see in 3D and correctly assess the topography, such as ditches, hills and hedges. Led by Professor Andrew Schofield, a team from Aston University’s College of Health and Life Sciences, together with Dr Isabel Sargent, previously at OS, carried out a study to understand how remote sensing surveyors interpret the shadows and highlights in images. The researchers asked six trained remote sensing surveyors and six novices to assess 10,000 stereoscopic aerial images of hedges and ditches, which had been heavily masked with image distortions. The stereoscopic images the aerial surveyors use for mapmaking are usually taken on sunny days. The human brain is naturally wired to interpret light as coming from above. However, the light does not come from above in the OS aerial images, it depends on the position of the sun. In the UK, north of the equator, light comes slightly from the south, thus appearing to come from below in images viewed by the surveyors. The researchers wanted to see how manipulating the direction of the light would affect the surveyors. Professor Schofield and the team swapped the image pairs between the eyes in half of the trials, so that hedges might look like ditches, and ditches look like hedges. The images were also flipped vertically on half the trials, changing the direction of the light source. Expert surveyors were found to rely on the stereoscopic cues – the difference in images seen by the two eyes – when performing the task. Novices were more likely to rely on lighting cues – highlights and shadows – to judge the shape and relief of an object, and assumed, as is natural, that the lighting came from above. With the manipulated images, this meant that novices frequently made mistakes. Experts were more accurate, even when the images had been turned upside down, and some had learnt to assume that the light source came from the south, or below. This is the first time anyone has shown that the natural assumption that light comes from above, which is common amongst many animal species, can be changed through long term experience. The researchers say that it could be used to develop new visual training techniques for remote sensing surveyors. For example, intensive exposure to repeated, difficult images can improve performance via a process called perceptual learning. Professor Schofield said: “This is a very exciting result. Others have shown that the light-from-above assumption can be altered by a few degrees, but no one has ever found complete reversals following long term experience. Dr Sargent said: “This result will help Ordnance Survey to understand the expertise of their staff and improve surveyor training and procedures.” Remote sensing surveyor Andy Ormerod, who worked on the study, said: “This research proves that experienced remote sensing surveyors can see the world differently. Whereas non-surveyors are used to seeing the world from one perspective, our brains have learned to view the world as seen from aerial imagery.” Journal of Vision DOI:10.1167/jov.24.4.11
