How a city walk may improve your mood: 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. Walking in the city might be just as good for our mood as walking in nature Time spent in urban environments is associated with depletion of cognitive resources and an increasing prevalence of mental illness. Few studies, however, have measured working memory capacity. Now, writing in Frontiers in Psychology, US researchers have compared memory performance and self-reported mood before and after a 30-minute walk in a natural or urban environment. The scientists assigned participants to either a nature or an urban condition and measured differences in self-reported affect and OPSAN, a complex measure of working memory capacity, before and after going on a walk in the respective environment. Their results showed that regardless of the setting, walkers exhibited an increase in positive affect and a decrease in negative affect, suggesting that going outside for a walk can boost mood regardless of environment type. They found, however, no significant changes in working memory […]

What does flattery do to our brains? 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. What praise and flattery does to our brains Both sincere praise and flattery are rewarding in different ways, but the various effects of these types of praise are not obvious. Now, researchers from Japan have published an article in Frontiers in Human Neuroscience in which they examined the brain activity of participants who received sincere praise or flattery after performing a visual search task. Using neuroimaging, the researchers found different effects of praise. The activation of the part of the brain modulating reward and pleasure processing was higher when participants received sincere praise than when they received flattery. The scientists also observed a socio-emotional effect, based on the positive feedback conveyed by praise. Altogether, they found that the neural dynamics of the rewarding and socio-emotional effects of different types of praise differ.

From microplastic waste to large, ancient squirrels: 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. UK seafloor sediments rich in microplastics For years, plastics have made up a large portion of the debris polluting the marine environment. Much of this plastic consists of particles under 5mm in any dimension. Writing in Frontiers in Marine Science, an international team of researchers from the UK and Norway examined the occurrence and abundance of microplastics in UK seafloor sediments between 2013 and 2021. The scientists used a fast-screening approach for the detection and quantification of microplastics in sediment samples. They detected microplastics in every sample collected from 15 sites around the UK, which supports the argument that seafloor sediments are suitable matrices for the long-term monitoring of microlitter. The adoption of seafloor sediments as a common indicator for microlitter for the north-east-Atlantic region would allow for future assessments at a regional level as well as regional action plans rather than isolated national remediation measures, the researchers pointed out. The […]

Five articles you need to check out on the future of astronomy and astrophysics

By Deborah Pirchner, Frontiers science writer Image: Shutterstock.com From uncovering the long-standing mysteries in extra-galactic astrophysics to understanding the properties of the sun’s outer atmosphere, astronomy research aims to help us understand what surrounds us. Frontiers highlights some of the top astronomy articles we have published recently. In a field as vast as space itself, cutting-edge work may be concerned with particles so small they are invisible to the human eye. Similarly, discoveries may be about whole galaxies. Those new findings, as well as advances in the theory, experiment, and methodology enable us to gain a better understanding of outer space. These five articles published recently as part of the Frontiers research topic ‘Horizons in Astronomy and Astrophysics’ cover important topics at the forefront of astronomy. Some Notes About the Current Researches on the Physics of Relativistic Jets Relativistic jets are powerful plasma jets emitted at the speed of light by black holes of some galaxies, massive stars, and neutron stars. In a review article published in Frontiers in Astronomy and Space Sciences, Italian researchers provided an effective critical review about one of the most long-standing mysteries in extra-galactic astrophysics: the origin of these ejections from the centers of galaxies.

From pylons to pandas: 5 Frontiers articles you won’t want to miss

by Angharad Brewer Gillham, 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, many often fly under the radar. Here are just five amazing papers you may have missed. Building better-looking pylons Pylons help support essential amenities – but they can be an eyesore. Italian scientists led by Dr Luca Di Angelo at University of L’Aquila investigated the best way to build a pylon with less visual impact on the landscape. As visual impact is subjective, reducing it requires consultation with residents who will see the pylons every day. But designs invented by residents without technical knowledge may not be able to meet safety standards. Di Angelo and colleagues used the development of new electrical pylons in the coastal regions of Italy to test a novel method of integrating visual impact minimization with the design process. They identified shapes which were related to the geography and culture of the area and streamlined enough for pylon design, and surveyed Italians from different coastal regions to determine which shapes were considered most recognizable and representative. A sail was chosen, and models were developed […]

5 articles you need to check out on the future of materials research

By Angharad Brewer Gillham, Frontiers science writer Image: Shutterstock.com In a fast-moving field of research like materials science, it can be difficult to keep up with the latest breakthroughs. Now at Frontiers, we highlight just five of the latest research articles to shed more light on the way we build our world around us, published by top researchers in the Frontiers in Materials Research Topic ‘Horizons in Materials’. Growing green technology: from trees to tech Scientists aiming to power the appliances of the future are developing special phenolic compounds from resins instead of petrol – a first step towards organic electrodes. Since biomass is the only green, renewable source of carbon materials, carbon-based electrodes for new-generation metal-ion batteries could be a more eco-friendly replacement for lithium-ion batteries. Some of the methods to make these compounds currently available are problematic because they require dangerously high temperatures and pressures and hazardous chemicals, but new methods are being developed which use mechanical forces instead. If these compounds can be developed into renewable sources for electronics, Dr Javier Quílez-Bermejo and his team at the Université de Lorraine point out, the potential for revolutionizing electronic devices would be huge, opening the way for greener fuel […]

From ghost gear to microbe memories: 4 Frontiers articles you won’t want to miss

by Angharad Brewer Gillham, 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, many often fly under the radar. Here are just four amazing papers you may have missed. The hunt for ghost gear 25-30% of the plastic waste in the sea is lost fishing gear, or ‘ghost gear’, some of it now up to 60 years old. This ghost gear devastates the environment not only through continuing to trap fish, but also by shedding microplastics into the environment which then enter the food chain. Once it sinks as far as the sea floor, it becomes invisible from above – a hidden threat to the marine ecosystem. A team led by Andrea Stolte from the World Wildlife Foundation, writing in Frontiers in Marine Science, reported a successful ghost-hunting collaboration between fisherfolk, scientists, and divers in the Baltic Sea. This coalition of stakeholders had several options for hunting down the ghost gear. Traditionally, when lost gear is spotted, fisherfolk use search hooks and other similar tools to try to retrieve it. However, this proved to be inefficient and damaging to the […]

From chili-heat pain relief to blue whale migration: 5 Frontiers articles you won’t want to miss

by Angharad Brewer Gillham, 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, many often fly under the radar. Here are just five amazing papers you may have missed. Chili to the rescue: Modulating capsaicin as a treatment for chronic itching Pain and itching are both signals that help humans protect themselves, by prompting us to end contact with whatever causes us pain or make us itch. However, they are also key symptoms of many disorders, and can be frustratingly difficult to treat. Scientists from the Universidad Miguel Hernández, writing in Frontiers in Molecular Neuroscience, investigated whether transient receptor potential channels, which pick up sensory cues ranging from the taste of wasabi to changes in pH, could help treat pain and itching. Previous attempts to exploit these channels to stop pain and itching have not been successful because they cause overheating as a side effect, so the authors suggested that ‘soft’ modulation of the channels might be more patient-friendly, targeting only the channels that aren’t working correctly. While there are several existing medications which use capsaicin to target these channels, […]

But with tens of thousands of articles published each year, many often fly under the radar. Here are just five amazing papers you may have missed. Scientists eavesdrop on minke whale conversations in Hawai’i Scientists writing in Frontiers in Marine Science used hydrophones to study hard-to-spot minke whales in Hawai’i, learning that they use their ‘boing’ calls more frequently when they are close to other members of the same species. Minke whales who visit this area are hard to study because they are small, solitary, and visit outside the times when most ship-based surveys are conducted. Passive acoustic monitoring, using hydrophones mounted on the sea bed, allows scientists to listen in on whales all year round. The authors used 47 hydrophones to record thousands of calls between 2012 and 2017. These calls were analyzed to detect individual whales and monitor their behavior in the study area. The minke whales used their ‘boing’ calls only between fall and spring, and called more rapidly when other minke whales were nearby. Because minke whales are so enigmatic, it isn’t […]

Researchers challenge claim of historic human brain ‘shrinking’ and 3 other papers you don’t want to miss

By Colm Gorey and Mischa Dijkstra, Frontiers science writers 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, many often fly under the radar. Here are just five amazing papers you may have missed. Researchers challenge idea that human brains shrank 3,000 years ago Last year, an article published to Frontiers in Ecology and Evolution made headlines across the world after it claimed human brains shrank in size approximately 3,000 years ago. This, according to the authors, may have driven by the externalization of knowledge in human societies, thus needing less energy to store a lot of information as individuals. As a result, we developed smaller brains. However, in a recent article, also published to Frontiers in Ecology and Evolution, another team of researchers challenged this notion, questioning several of the original paper’s key hypotheses. Speaking to his university, the University of Nevada, Las Vegas, anthropologist Brian Vilmoare said that “human brain size has not changed in 30,000 years, and probably not in 300,000 years”. In fact, he added, “based on this dataset, we can identify no reduction in brain size in modern […]

Key to life found at the centre of our galaxy and bee ‘waggle dances’: Most viewed articles of July 2022

By Colm Gorey, Frontiers science communications manager Image: Shutterstock.com Each month, Frontiers shines a spotlight on some of the leading research across a wide range of topics. Here are just some of the highlights that resonated strongly with readers on our news site in the month of July. Building blocks for RNA-based life abound at center of our galaxy Nitriles, a class of organic molecules with a cyano group, that is, a carbon atom bound with an unsaturated triple bond to a nitrogen atom, are typically toxic. But paradoxically, they are also a key precursor for molecules essential for life, such as ribonucleotides, composed of the nucleobases or ‘letters’ A, U, C, and G, joined to a ribose and phosphate group, which together make up RNA. Now, a team of researchers from Spain, Japan, Chile, Italy, and the US show in Frontiers in Astronomy and Space Sciences that a wide range of nitriles occurs in interstellar space within the molecular cloud G+0.693-0.027, near the center of the Milky Way.

But with tens of thousands of articles published each year, many often fly under the radar. Here are just five amazing papers you may have missed. Impact of Alzheimer’s on the brain may be greater than previously thought A significant review of more than 200,000 scientific publications has shown that the effects of Alzheimer’s disease on the brain are far broader than initially thought. Writing in their review article in Frontiers in Aging Neuroscience, the international team of researchers said that they wanted to understand the breadth and diversity of biological pathways – key molecular chain reactions that drive changes in cells – that contribute to Alzheimer’s disease by research over the last 30 years. They found that while nearly all known pathways have been linked to the disease, the most frequently associated biological mechanisms have not significantly changed in the last three decades, despite major technological advances. These include those related to the immune system, metabolism, and long-term depression. They also found that the top-ranked 30 pathways most frequently referred to in literature remained relatively consistent […]

But with tens of thousands of articles published each year, many often fly under the radar. Here are just five amazing papers you may have missed. Daily eating of cranberries may give us a memory boost and lower ‘bad’ cholesterol The famous proverb says that an apple a day keeps the doctor away, but a recent study published to Frontiers in Nutrition has found that significant health benefits may come from eating a cup of cranberries a day. A team of researchers from the UK, the Netherlands, and Italy set out to see what benefits this daily dose of the popular berry would have on those aged between 50 and 80. Of those taking part in the study, half ate freeze-dried cranberry powder equivalent to 100g of fresh cranberries, while the other half were given a placebo. The results showed that those who were eating cranberries daily saw a significant improvement in their memory of everyday events, neural functioning, and delivery of blood to the brain. The researchers hope that their findings could have implications for […]
